There are several apps that let you turn 2 phones or tablets into a monitor, functioning as either an audio or video monitor, depending on the app. These are often not as sensitive or as high quality as specially designed baby monitors.

This monitor is placed underneath your baby's cot sheet. It sends an alarm if your baby does not move for a set time. There are no approved standards in Australia for movement monitors sold to the public. These monitors use electrode dots attached to the baby's chest to monitor chest movement and the electrical activity of the heart.

An alarm goes off if the heart rate falls below a set level, or if there is a long pause in the baby's breathing. Sometimes, these monitors come in the form of a wearable device. Some of them are linked to a computer, which assesses how serious the situation is.

These are used in hospitals, but not often at home. They send an alarm when the oxygen recorded in the baby's skin falls below a set level. They can sometimes send false alarms. These monitors use lights or vibrations to tell hearing impaired carers that their baby is awake and needs their attention.

A baby monitor is only an alarm. It will not save your baby's life on its own. As the baby's carer, you need to be able to respond to the alarm and know what to do. For example, you might want to make sure your CPR skills are up to date. It is also good to make sure everyone who looks after the baby knows what to do in an emergency situation.

It is important to talk to your doctor before buying a monitor to learn how to respond to a monitor's alarm. Monitors are not always accurate and the alarms can go off when nothing is wrong. This can be very stressful for parents. They can also stop working if the power, battery or Wi-Fi fail.

There have been some cases in Australia with babies getting caught up in the electrical leads attached to monitors. Be sure to always use the monitor according to the instructions on the package. Look for monitors that will transmit small sounds, even when you are far away.

Check the camera has a wide enough angle to view the baby at all times, and has different channels so you can avoid radio interference. Other features you might look for are being able to use different cameras in different rooms, lights as well as sounds to alert you to your baby's crying, battery as well as mains power in case of power failure, and different camera mount types.

The docking station 26 can be configured to receive and recharge the parent unit The opposite side of the parent unit 22 in this example includes a light 32 as a battery indicator and a DC adapter jack 34 with a rubber cover covering the opening.

A DC adapter 36 can be used to power the parent unit via an ordinary AC source The battery indicator 32 can illuminate in more than one color and, in one example, can illuminate green when recharging or when being used remotely with a good battery charge.

The light can illuminate red when the batteries are low. Clearly, many other examples can employ different configurations and constructions relative to the docking station, the battery, the parent unit shell, and the arrangement of the buttons and switches on the parent unit.

In one example, the child unit 24 can also incorporate a parent finder button 44 , which can be depressed to emit a sound on the parent unit 22 , if turned on, so that the parent unit can be easily located.

In this example, the child unit 24 also comes with a conventional AC adapter 46 and a DC adapter jack 48 on the back of the unit as shown in FIG. Thus, each of the units 22 and 24 can operate either by on-board, rechargeable or replaceable batteries, or by externally supplied AC power using an AC wall jack and a DC adapter.

The above-described features of both the parent and child units are similar to features found in other baby monitor systems. Additionally, the parent unit 22 can be provided with a belt clip 52 as shown in FIGS. That way the parent unit 22 can be carried by a parent as needed.

As shown in FIG. A green LED mode can indicate that the power to the unit is on and, if running on batteries, the batteries are fine. A red LED mode can indicate that the batteries are low when the unit is on. The parent unit 22 has a plurality of passages or openings 60 on the front surface that open to a speaker in the unit.

The child unit 24 similarly has openings 62 in the front surface that are open to a microphone so the unit can pick up sounds. The parent unit 22 includes an array of sequential LED lights in the form of a light bar or series of lights One of the lights in the light bar 64 of the parent unit 22 can be a connection light that indicates a good connection between the parent and child units when in use.

By using the above reference numbers, the above-described system 20 including a parent unit 22 and child unit 24 with the various buttons, lights, and connectors are generally incorporated into each of the more detailed descriptions below for various features disclosed herein.

As will evident to those having ordinary skill in the art, the configuration, arrangement, positioning, availability, and the like of the parent and child unit shells, lights, buttons, and switches can vary considerably and yet fall within the spirit and scope of the present invention.

In this example, the system 20 includes at least two child units 24 and at least one parent unit In this example, the child units 24 each have a microphone 68 and a transmitter Each unit picks up sound through its own microphone 68 and transmits appropriate signals representative of the sound to the parent unit In this example, the parent unit 22 includes two or more distinct receivers 72 A and 72 B, each dedicated to a particular child unit so that the parent unit can simultaneously receive signals from both child unit transmitters The parent unit also includes a sound processor 74 that differentiates the sound information transmitted by the two child units The sound processor module can then receive those signals from each receiver, combine the signals into one audio signal and deliver those to a speaker The sound processor can then keep the audio information from each receiver segregated and deliver the information separately to a dedicated meter or light bar 78 A or 78 B.

In this example, the processor 74 in the parent unit 22 delivers the sound information independently and simultaneously to the speaker The speaker audibly emits the sound information simultaneously from both child units 24 in this example. The processor 74 also simultaneously transmits segregated signals representative of the sound information received from the two child unit transmitters 70 , each to its own independent sound level meter 78 A and 78 B in the parent unit.

In one example, each of the sound level meters can be an independent light bar or LED display as is known in the art, and as represented in FIG. Each sound level meter 78 A and 78 B can independently indicate the volume or amplitude of the sound information received from its particular child unit Thus, in this example a parent can listen to any audible sound information from the speaker The parent can then also view the two sound level meters 78 A and 78 B to determine which, if any, of the child units 24 is picking up and transmitting sound information.

As a result, a parent can simultaneously receive information from and monitor both child units at the same time. In another alternative example, it is possible to have multiple parent units, each with the same function as the single parent unit described in these examples.

In a further example, the parent units can also include more than the two sound level meters as shown, depending upon the number of independent child units to be monitored.

In another example, a parent unit 22 could be provided with only a single receiver, and yet still listen to two child units. This can be accomplished by having the child units alternate their transmissions. The child units can not transmit at the same time. One will transmit for a short time and then stop.

Then the other will transmit for a short time and then stop. This is known as Time Division Multiplexing. In order to accomplish this, each child unit must also have a receiver and listen to see if another child unit is receiving. The parent units must also include a transmitter.

Once the parent unit receives a transmission from a child unit, it can send a command for the other child unit to transmit. In this example, the parent unit 22 again monitors more than one child unit simultaneously.

However, the parent unit in this example displays the information to a user differently than in the prior illustrated example. This example is again shown using only two child units 24 and a single parent unit The parent unit 22 in this example includes a receiver 80 , a sound processor 82 , and a speaker 84 , similar to the previous example.

In this example, the sound processor 82 combines the signals from the two child units 24 from the receiver 80 into one real-time output that represents only the output from the child unit that currently transmits the higher sound amplitude to the speaker In this example, the parent unit also includes only a single sound level meter The sound processor delivers the combined real-time output that again corresponds to which ever child unit is presently transmitting the higher amplitude sound information.

The parent unit 22 in this example includes two lights or LED's 88 A, 88 B, one for each of the child units A threshold reference can be set in the sound processor so that when a first child unit transmits information above the threshold reference, the light 88 A for the first child unit illuminates.

Similarly, when the sound level or amplitude from the second child unit surpasses the threshold reference, the light 88 B is illuminated.

In this example, each of the lights 88 A and 88 B can be a single individual light that either increases in brightness or blinks more rapidly as the amplitude increases, or can be an array of lights with more being lit as the amplitude increases.

These types of buttons are known for use with respect to a number of electronic devices available on the market. However, such devices are not used in a baby monitor system. The momentary button configuration provides a user interface with a more advanced appearance and feel and can be incorporated in a system that has more advanced electronics.

Also, consumers will recognize and reach a certain comfort level when using the momentary buttons of the system because such buttons are found on many other electronic devices. The schematic shown in FIG. These advantages go beyond the mere improved or perceived high-tech feel achieved by adding a momentary or soft-touch button.

Using the diagram, with a unit in the OFF state, the gate-to-source voltage of the transistor Q 3 is 0 volts, which shuts off the transistor Q 3.

When an operator presses the switch SW 1 , voltage at the capacitor C 6 is conducted through the switch and turns on the transistor Q 4.

This then sequentially turns on the transistor Q 3. This allows voltage to be applied to the input of the voltage regulator U 1. The output of U 1 then moves or latches the transistor Q 4 in the ON state.

The ON state will remain until someone actuates the switch SW 1 again. Once the switch SW 1 is depressed again, the voltage across the capacitor C 6 drains to 0 volts and is conducted through the switch, which turns off the transistor Q 4.

This sequentially turns off the transistor Q 3 , which in turn shuts off power to the regulator integrated circuit U 1. Once the switch SW 1 is depressed turning off the system, the system will remain in the OFF state until a user again depresses the switch SW 1.

The location of the transistor Q 3 in this example prevents current from either the DC power jack or the battery pack BP 1 from flowing into the regulator integrated circuit U 1. In this way, the current from the battery is extremely low when the system is turned off, which helps to insure and maintain a long batter life.

In the same diagram, the resistors R 1 , R 2 , and transistor Q 2 combine to form a circuit that automatically connects the Q 3 and Q 2 transistors to either the battery pack BP 1 or the wall supply power source.

When the wall supply is connected to the jack J 1 , the gate-to-source voltage of the Q 2 transistor is positive. In this state, the transistor Q 2 is turned off and no current will flow from the battery pack BP 1 to the rest of the circuit.

This isolates the battery from the remaining parts of the circuit. When the voltage from the wall supply at the jack J 1 is low or disconnected, the gate-to-source voltage at Q 2 is negative, which turns on Q 2.

Thus, current can then flow from the battery BP 1 to the rest of the circuit with minimal voltage loss across the transistor Q 2. The diode D 2 in the circuit prevents current from flowing from the battery pack into the DC power jack.

The switch circuit shown in FIG. Use of this type of circuit can result in zero or nearly zero power dissipation when the power to the units is turned off.

This conserves battery life by not draining batteries through the circuit. The disclosed circuit can also result in an automatic and seamless switch-over from an external AC power source to the DC battery power source if the AC power source is lost.

The system can also recharge the battery pack BP 1 and provide power to the product when the unit is powered on and being supplied with power from the AC power source. However, in using this alternative arrangement, the microprocessor typically must be powered on at all times and thus may result in unwanted current consumption even when the units are powered off.

Another advantage of the circuit disclosed in FIG. Existing baby monitor systems typically each charge their batteries at a much lower rate when the unit is powered on. In another aspect of the present invention, a baby monitor system 20 can be configured as shown in the schematic of FIG. This example can eliminate the need for a separate integrated circuit previously used solely to control or manage the sound lights or LED display.

In this example, a child unit 24 employs a microphone as a transducer and an amplifier that amplifies the signal of the transducer. The child unit 24 also has an analog-to-digital converter ADC that converts the analog signal from the microphone amplifier to a digital audio signal.

The child unit 24 also has a microprocessor that receives and processes the digital audio signal and transmits a digital data stream. The digital data is then sent by the microprocessor to a radio frequency RF transmitter in the child unit. A parent unit 22 in this example includes an RF receiver that receives the RF transmission of the digital data stream from the child unit.

The RF receiver provides the information stream to a microprocessor that processes the digital data. In this example, the microprocessor can determine the amplitude of the audio signal from the child unit 24 and is capable of controlling the LEDs of the light bar sound level meter on the parent unit The microprocessor directly controls the LED display without the need for a separate integrated circuit.

The microprocessor can also control sound information sent to the speaker of the unit. The microprocessor in this example also sends the digital audio data to a digital-to-analog converter DAC that converts the data to an analog signal.

The analog audio signal is sent from the DAC to a speaker amplifier in this example, which then sends the amplified audio signal to a speaker of the parent unit. With this parent unit arrangement, the LED display can be controlled for purposes other than illuminating according to the amplitude of the audio signal from the child unit.

Since the microprocessor in the parent unit directly controls the LED display , it is an option to have the LED display convey other information. As the volume is turned up by a user, the LED display can illuminate more lights and vise versa.

In another example, the microprocessor in the parent unit can be configured to generate a sound data that is converted into an analog audio signal by the DAC The sound signal can then be sent to the speaker amplifier and speaker The amplitude of this sound can be changed by the microprocessor according to the volume setting to further reinforce the current volume setting to the user.

The microprocessor in the parent unit can also be utilized to convey other sounds through the speaker in the same manner. For example, when the unit is turned on and off, an alert sound can be generated. Alternatively, when an audio signal from the child unit reaches a certain threshold, a sound can be generated to alert anyone near, but not looking at, the parent unit In yet another example, the LED display can be manipulated by the processor to illuminate in a pattern that represents the parent unit 22 searching for a signal from the child unit There are certainly other forms of information that could be conveyed from the microprocessor via the LED display and the speaker in this example.

The arrangement shown in FIG. In another example, the child unit microprocessor may determine the amplitude of the audio signal and then convey that information to the parent unit 22 with an indication of the audio amplitude. The parent unit 22 in such an example can receive the information and then make a determination as to how to represent this information on the LED display In yet another example, the child unit microprocessor can be utilized to determine the amplitude of the audio signal and make the further determination as to the particular light pattern to be displayed by the LED display This information can then be digitally conveyed to the parent unit 22 , which would receive the information and merely turn on the predetermined display pattern.

The concept shown in FIG. First, the monitor arrangement eliminates one integrated circuit from the system, reducing cost and space requirements on the circuit board within the unit. Second, the concept also permits creative control and flexibility in how the LED display illumination patterns, as well as the speaker , can be operated and controlled and for what purpose.

In yet another aspect of the present invention, an inexpensive and less complex RF modulator circuit is disclosed that yields a number of benefits for use in baby monitor systems. Conventional baby monitors use a simple switch and potentiometer arrangement that sets the DC voltage at the control input of a voltage controlled oscillator VCO.

This type of arrangement in a baby monitor system is relatively low cost but requires a user to manually move a switch to determine the channel or transmit frequency for the unit.

In general, the prior art unit has a microphone and an amplifier that deliver an amplified analog audio signal to a high pass filter The unit also includes a user-actuated switch that selects between first and second DC voltages A or B.

The selected DC voltage is then added through a low pass filter to the high pass filtered amplified analog signal. The combined voltages are then sent to a RF VCO, which then further sends the data stream to a RF transmitter.

In this aspect of the present invention, the user selection method is eliminated. The unit 24 in this example also includes a microphone and a microphone amplifier to produce an amplified analog audio signal detected at the child unit. The amplified analog audio signal is then converted to a digital audio signal with an ADC that is also provided in the child unit The digital audio signal is then transmitted to a microprocessor in the child unit.

The microprocessor arranges the digital audio information into a digital data stream suitable for transmission. The microprocessor also sends digital information to two different components. First, the digital data stream is sent to a high pass filter that removes the DC component from the data stream.

Simultaneously, the microprocessor sends digital data to a digital-to-analog converter DAC The DAC generates an analog voltage that is used to determine and control the transmit frequency of the information. The microprocessor can send different data to the DAC to change the transmit frequency.

The analog voltage is delivered to a low pass filter that insures that the analog voltage is a stable DC voltage. The filtered analog voltage and the filtered digital data are added together and then delivered to a RF VCO The VCO is configured to generate a high frequency signal that is controlled by the input signal.

The DC component of the input signal determines the base transmit frequency of the information transmitted from the child unit. The digital data stream modulates the base frequency to create a RF frequency shift keyed signal.

The modulated RF data stream is transmitted by a RF transmitter to then be received by a parent unit In one example, a user can push a button 42 on the child unit 24 to cause the microprocessor to select the next channel or transmit frequency, from a plurality of different frequencies, such as six different channels.

In an alternative example, the child unit may send analog data instead of digital data to the voltage controlled oscillator or VCO. In this example, the child unit 24 includes a microphone for picking up sound adjacent the child unit and transmitting the sound to an amplifier The amplified analog audio signal is sent to a high pass filter Shop the look.
