This invention relates to wireless communication systems. More specifically, this invention relates to wireless audio and/or video systems for transmitting media data between locations corresponding to wireless devices and controlling load circuits therefrom.
Wireless networks can be used to transmit information from one location to another location and or to broadcast information from one location to multiple location. Information that is transmitted over a wireless network can include configuration and execution data, text, voice and video data, the temperature and humidity readings at the perspective locations. Wireless networks have continued to develop and applications have significantly grown as faster transmissions of larger quantities of data are now possible.
Wireless networks provide number of advantages over hard-wire networks. Wireless networks allow you to eliminate messy cables. Wireless connections offer more mobility, the downside is there can sometimes be interference that might block the radio signals from passing through. One way to avoid this is by putting the source of your wireless connection in a place where the signal will have as little interference as possible. Sometimes nearby networks are using the same frequencies, this can also cause interference within the network and can reduce its performance.
Another problem with wireless networks is that they are more vulnerable to access from unwanted sources or “intruders.” Many networks offer WEP—Wired Equivalent Privacy—security systems which have been found to be vulnerable to intrusion. Though WEP does block some intruders, the security problems have caused some businesses to stick with wired networks until security can be improved. Another type of security for wireless networks is WPA—Wi-Fi Protected Access. WPA provides more security to wireless networks than a WEP security set up. The use of firewalls can also help to prevent security breaches.
While wireless communications and devices have greatly improved, hard-wire networks remain dominantly used for a number of applications, at least in part due to security and privacy issues described above.
The invention is directed to a wireless system that is used for communication, security, indoor and outdoor weather monitor controlling electrical circuits and lighting. The system is configured to be used in any building, but is preferably configured to be used for residential buildings. The system includes a plurality of devices. At least a portion of the devices are hardwired to the load circuits, referred to herein as monitor devices, and at least one of the devices, referred to herein as a master control device is a mobile remote control device. Preferably, all of the system devices, monitor devices and control devices, are configured to transmit media data between each other over a wireless peer-to-peer network, where by data is transmitted in radio packet form. However, it will be clear to one skilled in the art from the discussion below that the devices of the present invention can communicate or transmit data between each other using any suitable network method or protocol. For example, monitor devices can communicate or transmit data between each other through power lines, routers, cables and any other suitable network hardware. The media data that is communicated or transmitted between devices corresponds to sound and/or visual media data that is collected, captured or recorded from the devices at their respective locations. Preferably, control devices are used to control the monitor devices and/or the load circuits through the monitor devices remotely.
In accordance with the embodiments of the invention, the system includes a plurality of monitor devices. The monitor devices are electrically coupled to load circuits and are configured to control the load circuit either manually or remotely using the master control device, such as described below. Preferably, the monitor devices include power circuitry and wire leads for coupling to load circuits and providing power to the monitor devices. Alternatively, or in addition to being powered through the load circuits, the monitor devices include a battery for providing power or chargeable battery charged by solar cells or charged by the ac EM field chargers coupled to the load circuits.
The monitor devices, in accordance with the embodiments of the invention, include a sensor unit. The senor unit includes a temperature sensor, a humidity sensor, a smoke sensor, a gas sensor, any other suitable sensor or combination of sensors. The sensor collects environment data corresponding to the locations of the monitor devices and periodically transmits the environment data to the master control device. For example, the sensor unit is a temperature and humidity sensor that monitors weather conditions at the respective locations of the monitor devices. The weather conditions are captured and digitized periodically by an ADC circuit of the monitor devices and the monitor devices periodically and automatically transmit weather data packets with weather information to the master control device, where up-dated representation of the weather data is displayed on an LCD screen at the master control devices.
As mentioned above, the sensor unit alternatively to, or in addition to, a temperature and humidity sensor includes a smoke or gas sensor for detecting the smoke or a gas leak. Where smoke or a gas is detected by the sensor, the monitoring devices automatically transmit an alarm signal to the master control device and/or trigger an external alarm.
The monitor devices include a monitor media capture unit configured to capture monitor media data corresponding the locations of the monitor devices. The monitor media capture unit includes, for example, a microphone and/or a camera. Where the monitor media capture unit includes a camera, the camera is any suitable camera configured to take still images, streaming live video data or a combination thereof.
A camera of the monitor device is preferably capable of panning and or tilting through a range of capture angles for effectively capturing a range of still or video images. The pan and tilt camera motion of traditional servo-motor controlled mechanism can result in EMI radiation, motor and gear noise, which can reduce the quality of the RF transmission performance and AV quality of the wireless system of the present invention. Further servo-motor mechanical structures and circuit designs for a camera motion system are too large to be readily adapted to a faceplate housing structure, such as described below.
Accordingly, a monitor device of the present invention preferably includes a micro-camera module with and a magnetic motion control mechanism for controlling movement of a camera unit remotely from a master control device through a user interface, such as described in detail below.
The monitor devices also include a monitor wireless transducer unit for transmitting the monitor media data and receiving control media data from a master control device. The monitor devices further include a monitor microprocessor unit programmed with firmware and other circuitry, such as shown in
In still further embodiments of the invention, the monitor devices include a monitor media output unit. The monitor output unit includes, for example, a speaker and/or a video screen to generate an audio and/or visual representation of the control media data received by the master control device.
The master control device also displays the temperature and humidity readings captured by the remote monitor device sensors at the respective locations.
The master control device includes a gas leakage alarm signal generator to respond to the gas leakage accident happening at the locations of the monitor devices. It automatically displays and identifies an environment image of the exact location happening gas leakage accident once the gas detector of monitor device is triggered.
The master control device includes a control media capture unit. The control media capture unit includes microphone and/or a camera, such as described above, or any other suitable components for capturing the control media data corresponding to a location of the master control device.
The master control device also includes a control wireless transducer unit configured to receive the monitor media data transmitted from each of the monitor devices and transmit the control media data to each of the monitor devices. The master control device also includes a microprocessor unit programmed with firmware and other circuitry, such as shown in

The control media output unit includes, for example, a speaker and/or a video screen to generate an audio and/or visual representation of the monitor media data transmitted to the master control device by each of the monitor devices.
In accordance with the embodiments of the invention, the master control device is configured to remotely control the load circuits through the plurality of monitor devices. In operation, the master control device can select any of the monitoring devices and play an audio or visual representation of the location corresponding to that of the selected monitor device. The monitor devices are selected by entering a code or dialing a number. The master control device is also configured to play an audio and/or visual representation of the locations of any number of the monitor devices simultaneously. While playing an audio and/or visual representation of one or more of the locations of any of the monitor devices, temperature and/or humidity readings corresponding to the one or more of the locations of any of the monitor devices can also be displayed on the master control device, through for example and LCD display.
In further embodiments of the invention, the monitor devices include a motion sensor unit. In accordance with this embodiment, the monitor devices are configured to control the load circuits based on motion detected by the motion sensor unit. The motion sensor unit includes an infrared motion sensor, an ultrasonic motion sensor or a combination thereof. In accordance with this embodiment, the system is capable of being placed into “Security Mode”. While the system is in Security Mode,” the monitor devices monitor rooms corresponding to their respective location. When motion is detected by one of the motion sensor units, the corresponding monitor device automatically collects or records monitor media data and transmits the monitor media data to the master control device. The monitor media data can then be played or displayed on the master control device and/or stored in the removable or permanent data storage unit, such as described below.
The system can also be configured to operate in a “Reminder Mode”. While the system is set in the “Reminder Mode” one or more of the monitor devices automatically recalls and displays or plays an audio and/or visual reminder message at the monitor devices, which has been previously recorded and stored in a memory storage unit of the master control device. In accordance with this embodiment of the invention, the monitor devices automatically recalls and displays or plays the audio and/or visual reminder message when the motion sensors of the respective monitor devices are triggered.
In a particular embodiment of the invention, the monitor devices includes a faceplate body configured to couple to and fit over a momentary switch that manually opens and closes a load circuit. Alternatively, the monitor devices are configured to couple to and fit into an electrical wall boxes and replace standard momentary light switches. In accordance with this embodiment, the monitor devices are configured to manually control the load circuits through a user interface, such as described below.
