Abstract:
A system and method for transferring power using a data communications signal line. The data communications signal line is in a high impedance powerless state when idle. A main device is electrically coupled to the data communications signal line. The main device generates and transmits a signal on the data communications signal line. The signal includes power generation and non-power generation characters. A peripheral device is electrically coupled to the data communications signal line. The peripheral device has a functional unit arranged to perform a desired function for the peripheral device. A power conversion module is electrically coupled to the data communications- signal line and receives the signal. The power conversion module converts power from the received signal to a form suitable for storage. A controller is in electrical communication with the functional unit and the power conversion module. The controller receives the power generation and non-power generation characters, strips the power generation characters from the signal and transmits the non-power generation characters to the functional unit.
Abstract:
A method for wireless synchronization of first (A) and second (B) magnetic electronic article surveillance (EAS) systems arranged for operation in close proximity to one another, comprising the steps of: programming each of the first and second EAS systems for transmitting at least one unique signal into respective and partially overlapping interrogation zones of the first and second EAS systems and for receiving any signals from the interrogation zones at respective and predetermined transmit and receive phases relative to a common reference; transmitting a unique signal from the first EAS system (30); receiving and identifying the at least one unique signal at the second EAS system during one of the receiver phases (50C); and, transmitting from the second EAS system synchronously with the transmitting from the first EAS system, responsive to the conveyed phase information (32).
