Patent CA-2584701-A1 (CA)
Title: Wireless signal distribution system and method
Inventor: WAKE DAVID
IPC: H04J14/02
Filed: 2005-10-17
Abstract: A communications system connects one or more BTS hotels with several remote access nodes on a transmission ring. Each operator has one or more separate optical wavelengths. Signal flow around the ring can either be uni-directional or bi-directional. Each optical wavelength (or wavelength pair) contains the wireless signal traffic for all remote nodes in the ring for the operator using that particular wavelength in digital form. At each node, the incoming signals are electrically demultiplexed and appropriate signals for that node are extracted for conversion to RF. These signals are copied rather than cut so that they are also available at following remote antenna nodes, thereby enabling simulcast operation.

Title: Handheld mobile communication device with flexible keys
Inventor: MOOSAVI VAHID
IPC: H04Q7/32
Filed: 2007-08-31
Abstract: Keypad keys for handheld mobile communication devices feature flexible key bodies and actuators extending from the key bodies. Switches below the actuators are connected in series circuits. All actuators beneath an intended key must be depressed in order for the circuit to be closed and the key to be recognized as actuated.  The flexible nature of the key bodies allows one actuator on a given key to be depressed while other actuators remain non-depressed. This prevents the key from being recognized as actuated when a only a portion of the key is depressed as occurs, for example, due to finger overlap.

Abstract: A system and method for communicating data between two nodes (1, 2) defines a plurality of separate partitions (A, B1 C) on each node and assigns one or more subjects to at least one of the plurality of the separate partitions. The subjects in each node communicate data with each other over one or more channels. For communicating the data, the present invention separates data communications on a channel from that of other channels. More specifically, each node runs under the control of a separation kernel (SK1, SK2) that partitions the nodes to define the subjects according to a separation kernel configuration data. A partitioning communication system (PCS1, PCS 2) separates the communications channels according to a PCS configuration data.

Abstract: Evacuation devices for evacuating the socket of a prosthetic limb, and prosthetic limb systems employing such vacuum devices. The evacuation devices each preferably include at least an electrically powered vacuum pump and a power source. Such evacuation devices can be attached at various locations on or in a prosthetic limb.

Inventor: LI SHIPENG
IPC: H04L9/30
Filed: 2006-06-29
Abstract: Systems and methods configured for recoding an odd integer and elliptic curve point multiplication are disclosed, having general utility and also specific application to elliptic curve point multiplication and cryptosystems. In one implementation, the recoding is performed by converting an odd integer k into a binary representation. The binary representation could be, for example, coefficients for powers of two representing the odd integer. The binary representation is then configured as comb bit-columns, wherein every bit- column is a signed odd integer. Another implementation applies this recoding method and discloses a variation of comb methods that computes elliptic curve point multiplication more efficiently and with less saved points than known comb methods. The disclosed point multiplication methods are then modified to be Simple Power Analysis (SPA)-resistant.
