Title: Antenna array having reduced sensitivity to frequency-shift effects
Inventor: HOCHWALD BERTRAND M
IPC: H01Q21/06
Filed: 2000-02-09
Abstract: We disclose a system for sending wireless communication signals on at least one downlink wavelength and receiving wireless communication signals on at least one uplink wavelength, wherein there is a ratio r equal to the larger divided by the smaller of these wavelengths. The system comprises a receiver operative to receive signals imposed on a carrier having the uplink wavelength, a transmitter operative to transmit signals imposed on a carrier having the downlink wavelength, and an array of independent antenna elements.      The array comprises a first and a second sub-array. One sub-array is electrically coupled to the transmitter, such that transmitted signals can be radiated from it, and the other sub-array is electrically coupled to the receiver, such that signals to be received can be extracted from it.   The sub-arrays are geometrically similar to each other with a relative scale factor equal to the wavelength ratio r.     The sub-arrays have at least one common antenna element.
Patent CA-2298660-A1 (CA)
Title: Medical photometer
Inventor: MENDELEYEV VLADIMIR
IPC: A61N5/06
Filed: 2000-02-07
Abstract: The present invention relates to a medical photometer, a device which measures the integrated and spectral reflected values of a biological tissue. Since background radiation is significantly reduced and the efficiency of reception of a light scattered from a biological tissue increases significantly, the reflected values are measured more exactly. Therefore, this type of medical photometer can be used in the real-time mode for remote diagnostics of inflammatory processes including oncology, prediction of illness tendency during the treatment process, and to refine the radiation dose for laser therapy (stomach ulcers, gastritis, bronchial asthma, illnesses of the prostate).        Description of the prior art There are many medical photometers for measuring the reflectivity of biological tissue. All of them measure only the integrated reflection in the narrow spectral range and use an optical fiber and an integrating sphere to receive light scattered from the tissue. Also, the power of light incident on a biological tissue is not regulated in the known solutions and therefore, the optimal power for received signals is not achieved. Because the optical transformation efficiency of an optical fiber and an integrated sphere is low and the background radiation is large in the known solutions, the signal-to-noise ratio is not sufficient to achieve the accurate reflectivity measurement required for the successful diagnosis and therapy.

Patent CA-2312682-A1 (CA)
Title: Reversible mortise lock
Inventor: LENK DAMON J
IPC: E05B59/00
Filed: 2000-06-28
Abstract: A reversible mortise lock comprises a latch bolt which is removable from the housing for ease of reversal. A securing member is disposed inside the lock housing for releasbly holding the latch bolt in the housing. The securing member includes a securing element having a blocking surface biased into engagement with the latch bolt for securing the latch bolt to the securing member. The securing element has a surface accessible from outside the lock housing which when pressed releases the latch bolt from the securing member. Once the latch bolt is freed, the latch bolt can be completely removed from the lock housing, reversed and reinstalled. This releasing surface is only accessible through the side walls of the lock housing. Therefore, latch bolt reversal must be performed before the lock is installed in a door. Once the lock is installed, the latch bolt cannot be reversed because the latch bolt cannot be removed from the lock. A locking mechanism for use in the lock comprises a blocking element in the housing and a toggle for manually moving the blocking element between a locked position and an unlocked position relative to a latch operator. A stop is removably attached to the blocking element and adapted in the locked position to prevent operation of the outside latch operator. The stop is also accessible through the side walls of the lock housing and positioning of the stop in the blocking element is accomplished before installation. Preferably, the stop is a threaded plug which is received in a threaded opening in the blocking element. Thus, a screw driver is the only tool needed to release the latch bolt from the lock housing for reversal of the latch boil and locking mechanism.
