摘要： Systems for determining a location of a portable device are provided. The system includes stationary infrared (IR) base stations, portable devices and at least one radio frequency (RF) transceiver. At least two of the IR base stations receive timing synchronization information and transmit corresponding IR location codes in a time period based on the received timing synchronization information. Each IR location code is representative of a location of the corresponding IR base station. Each portable device detects the IR location codes and, if one of the IR location codes is detected, transmits an output signal including a portable device ID representative of the portable device and the detected IR location code. The RF transceiver periodically provides, upon a request, the timing synchronization information to the respective IR base stations relative to a unified time of origin.

摘要： Methods and systems for determining a location and an identity of a portable device are provided. The system includes apparatus for transmitting timing synchronization information, a plurality of stationary infrared (IR) base stations and a plurality of portable devices. Each IR base station is configured to receive the timing synchronization information and to transmit a corresponding IR location code in a time period based on the received timing synchronization information. Each portable device is configured to: 1) receive the timing synchronization information, 2) detect the IR location codes from the IR base stations and 3) transmit an output signal including a portable device ID representative of the portable device and the detected IR location code. Each portable device is synchronized to detect the IR location code in the time period based on the received timing synchronization information.

摘要： A receiver includes two receiving modules, where the first receiving module is extremely parsimonious on battery power and as long as it is successful in developing a proper output signal at a given port maintains the second receiving module off, or substantially off. When the signal output of the first module drops below a preselected output, the second receiving module is enabled to develop and apply an output signal to the given port.

摘要： Methods and systems for determining a location and an identity of a portable device are provided. The system includes apparatus for transmitting timing synchronization information, a plurality of stationary ultrasonic base stations and a plurality of portable devices. Each ultrasonic base station is configured to receive the timing synchronization information and to transmit a corresponding ultrasonic location code in a time period based on the received timing synchronization information. Each portable device is configured to: 1) receive the timing synchronization information, 2) detect the ultrasonic location codes from the ultrasonic base stations and 3) transmit an output signal including a portable device ID representative of the portable device and the detected ultrasonic location code. Each portable device is synchronized to detect the ultrasonic location code in the time period based on the received timing synchronization information.
