Patent CA-2288261-A1 (CA)
Title: Filmless photon imaging apparatus
Inventor: ZERMENO ALFONZO
IPC: G01N23/04
Filed: 1998-06-18
Abstract: Filmless photon imaging sensor plates (20) which are particularly effective in medical radiology and industrial applications including, but not limited to high resolution mammography. The sensor plates (20) provide rapid production of high resolution images which exhibit a higher sensitivity and a wider dynamic range than contemporary X-ray systems.  Sensor plate (20) structures provide images having attributes of increased sensitivity; dual plate (20) design providing increased pixel read-out speed and differential dual energy image production; and electrically isolated segments (102A-H) by which a plurality of pixels are read concurrently to reduce overall image processing time. Generally, the plates (20) employ a homogeneous photoconductive material such as amorphous selenium and are read by exposing each pixel sized area to a small diameter light beam. Using light beam scanning, the resulting plate (20) design promises low cost manufacture of the sensor plates (20). The application of electric fields during plate (20) preparation, exposure, and read-out provides improved performance.
Patent CA-2291673-A1 (CA)
Title: Paging method and apparatus with acknowledgement capability
Inventor: FINES PANAGIOTIS
IPC: H04L1/00
Filed: 1998-04-02
Abstract: A radio frequency paging service has one or more TDMA return channels (R) in which terminals (14) acknowledge receipt of messages having an acknowledge flag set. In one alternative, slots are allocated in the return channel (R) by a slot allocation field in the respective messages. In another alternative, each terminal (14) monitors the messages addressed to other terminals (14) to determine which of them require a response, and determines, from the order of a message addressed to itself among the messages requiring a response, which slot to use for acknowledgement. The TDMA return channels (R) include unreserved slots which terminals (14) access on a contention basis. The frequencies of transmissions in the slots are randomized within a predefined limit to reduce the probability of interference between different terminals (14) in the same unreserved slot. The predefined limit is based on the maximum differential Doppler shift between terminals (14). The return channels (R) are allocated as a continuous block of frequency channels, thereby reducing signalling overhead when allocating these channels, and allowing the block of channels to be decoded by a single DSP. Data bursts transmitted by the terminals (14) in the return channels (R) are half-rate convolutionally encoded and interleaved so that the transmitted bit sequence contains alternating bits from the two outputs of the half-rate encoder. Each terminal (14) is identified by a forward identity code in received messages and by a return identity code in transmitted messages, the identity codes being related by a predetermined algorithm.
