摘要:
A synchronizing method and system between a Radio Frequency (RF) transmitter and a battery powered receiver wherein the transmitter transmits short duration first periodic sync signals which are used by the receiver to maintain proper synchronization of the receiver with the transmitter during second periodic wake-up windows for transmission of data. The receiver wakes for a short duration at the start of each periodic wake up window to receive a possible transmission of data, and if no transmission is received goes back to sleep, and if a transmission is received stays awake to receive the full transmission of data. The basic principle is that the average current consumed by the battery powered receiver in order to wake periodically to receive the first periodic sync signals and the second periodic data transmissions is less than the average current required to maintain the receiver awake continuously. The duration (e.g. 14 ms) and periodicity of (e.g. every 32 s) of the periodic signals are selected to meet a FCC regulation of 2 second/hour allowed for synchronization.

A system and method to use bar codes to facilitate obtaining information as to a product or service. A smart phone, with a downloaded scanning app. can scan a bar code associated with a product or service. Information can be extracted from the code by the phone and the scanning app. and forwarded automatically to a web server, via one or more computer networks. The server can analyze the information and extract other, responsive data from its data base. The responsive data can be downloaded to the scanning device for use with the product or service.

A security system, such as in a home or other building, includes a broadcast band RF transmitter for transmitting an audio message that can be received by a user on a common home or car radio, for example. The audio message may be provided in response to a command that is transmitted to the security system by a user from a wireless key fob or the like. The user command may instruct the security system to arm or disarm itself, for instance. The audio message, which can be received on a selected channel on a car's radio receiver, informs the user that the command has been executed. The audio message may include a voice message such as “system armed” or “system disarmed”, a musical passage, a beep, chirp, or the like.

An inventive system and method for a buddy security system is presented. The system and method enable the buddy security system in which messages can be exchanged between two distinct security systems. The inventive system is operable on a network having dynamic IP addresses using a centralized database of real time IP addresses. An MSO maintains the centralized database including basic information for connecting the control panels of the security systems to each other. The first and second security systems each have a control panel having a dynamic IP address; the control panel of the second system provides information to and can be controlled by the control panel of the first system. The dynamically IP address of each control panel is obtained from the centralized database.

A rotatable wireless electrical coupler is disclosed that presents a wireless alternative to mechanical slip rings, such as are used in rotatable mechanical assemblies such as dome cameras. The rotatable wireless electrical coupler is designed to provide for the wireless transfer therethrough of electrical power, video and data signals. A rotatable multi-function transformer of the electrical coupler is designed primarily for the transfer of electrical power therethrough, and can also be used for the transfer of data signals. A rotatable electrical capacitor of the electrical coupler is designed primarily for the transfer of video data signals therethrough, and can also be used for the transfer of control and feedback data signals. In a dome camera, the rotatable wireless electrical coupler transfers power and data signals to and from a rotatable platform/section on which is mounted a video camera, pan and tilt motors and other associated electrical components.
摘要:
A method of operating a security system by generating an instant message at a first location, the instant message including security system data, then transmitting the instant message from the first location over a computer network to a second location via an instant message server computer. The instant message is received at the second location, and a security system function is initiated at the second location based on the security system data from the instant message. Security system configuration data may be provided with an instant message in order to enable remote programming of the security system via the instant messaging channel. Half-duplex audio communications may also be achieved by providing digitized audio files with instant messages that may be communicated between locations.

摘要:
A security system comprising a plurality of remote wireless units, a central control unit and an adaptive console for translating messages in radio frequency signals into messages in signals suitable for transmission over a wire in order to augment the wireless capability of the system. The adaptive console has a wireless receiver for receiving the radio frequency signal, which includes identification and status information from a wireless remote units. The adaptive console also has a processing unit which translates the identification and status information from the radio frequency signal to corresponding function data derived from a mapping of valid identification and status information to function data, the function data emulating data generated by keypresses on a keypad that is representative of a function to be performed by the security system. The adaptive console also has a transmitter which transmits a signal over a wired connection which includes the corresponding function data to the central control unit or a wired security unit. The adaptive console may additionally have components enabling it to receive a signal from a wired connection, translate that signal to valid identification and status information, and then transmit a second radio frequency signal to the wireless remote units. Alternatively, the central control unit may contain the mapping and perform the translation from valid identification and status information to function data.
摘要:
A method for increasing the dynamic range of the receiver/control unit of an alarm system. The alarm system comprises the receiver/control unit, the receiver comprising at least one antenna apparatus and apparatus for switching the antenna apparatus. The control unit, or processing apparatus, comprises signal detection apparatus and apparatus for controlling the antenna apparatus switching. The method comprises the steps of selecting an input to the receiver, wherein the input maybe an output of one or more antenna apparatus or no antenna apparatus, and detecting the presence of a signal. The basis of the apparatus alarm system is the selection of no antenna, which causes the receiver to be approximately 12 dB less sensitive. The switching of the antenna apparatus is preferably accomplished by processor control of switching diodes. This allows the receiver to detect signals from remote transmitting devices located nearby without saturating the receiver, thereby increasing the dynamic range of the receiver/control unit.

A security system installation kit carries a coded designation of the characteristics of the components of the kit. An installer can use a wireless telephone, which is executing a scanning application, to sense or read the coded designation. The telephone can transmit the component parameters to an installation server. The server can transmit installation instructions back to the telephone. Those instructions can be visually or audibly presented to the installer facilitating the process. The installer, via the telephone and the server, can test the installed components for proper operation.
