Title: Automatic transmit power control
Inventor: BABA SATOSHI
IPC: H04B1/04
Filed: 1992-11-19
Abstract: An automatic transmit power control (ATPC) system is used in radio equipment of a cross polarization interference canceler system (XPIC system), in which two orthogonally polarized waves of the same frequency channel are used independently of each other. At the receiver the vertically and horizontally polarized waves from an antenna (15) are applied respectively to receivers (17a, 17b) which compare the received signal strength with (a) a threshold and (b) the adjacent channel interference. A control link (19) from the receiver to the transmitter controls the transmit powers of the two polarized waves of the object frequency channel simultaneously so that they are increased when a drop in the received signal level of either one of the two polarized waves is detected. <IMAGE>

Title: Queue management systems
Inventor: CHRISTIE MARTIN STUART
IPC: G07C11/00
Filed: 1994-11-01
Abstract: A queue management system is provided for monitoring and directing individuals waiting in a waiting area for interaction with a plurality of service locations. The system comprises sensing means (20) in or near the waiting area which sense each individual entering or in the waiting area. Each of the service locations has signalling means (44) which can be operated to provide a signal when the service location is free for use by an individual. A recording means (2) records signals from the sensing means (20) and the service locations (44) so that the number of sensed individuals who attend service locations can be determined. A further "no-queue" sensor can be positioned at the head of the queuing position which will recognise when no individuals are present. A "no-queue" signal sent to the central control unit will cause it to override or ignore signals received from the locations. The system allows the monitoring of service location usage and queuing time and allows decisions to be made by the manager of the system about how many service locations need to be provided to provide an efficient service. <IMAGE>
