Patent CA-2472125-A1 (CA)
Inventor: VERNON SCOTT D
IPC: H03F3/34
Filed: 2003-01-14
Abstract: A low-power operational amplifier comprises a differential input-stage and an output stage. The differential input-stage includes first and second differentially coupled input transistors each having base, emitter, and collector electrodes. A first current mirror circuit is coupled to the first and second input transistors and produces a first current, which perturbs the current flowing through the first input transistor. The output stage is coupled to the differential input-stage and to the current mirror circuit and produces a second larger current, which perturbs the current flowing through the second input transistor. The ratio of the emitter areas of the first and second input transistors are selected to substantially eliminate offset voltage caused by the difference between the first and second perturbing currents. This device is especially suited for low-power Class A bipolar operational amplifiers such as the type employed in low-power medical devices.

Title: Method for studying an object and an optical interferometer for carrying out said method
Inventor: GELIKONOV GRIGORY VALENTINOVIC
IPC: G01N21/45
Filed: 2003-02-10
Abstract: The invention relates to the studies of internal structures of objects with the aid of optical means. According to one variant of the inventive method and interferometer for carrying out said method, the optical beam path for low-coherent radiation directed towards the studied object (8) is embodied in such a way that it is bi-directional, the optical beam path for reference low-coherent radiation being embodied such that it is uni-directional. According to another variant of said method and interferometer, the reference optical beam path is embodied in the form of a loop (23). A part of said reference radiation travels along the beam path in a clockwise direction, the other part thereof travelling along said beam path in a conterclockwise direction. In the second variant, splitting factors can be optimised by embodying optical splitters (21) and (24) in such away that they are nonreciprocal or polarisation-dependent and by introducing polarisation-modifying elements between said splitters (21) and (24) and / or into a measuring arm and reference arms. The inventive variants of the method and interferometers for studying an object ensure the independence of the splitting and mixing radiation factors, thereby making it possible to control the power of a radiation source. Said splitting and mixing factors can be defined with respect to the best signal/noise relationship at the specified power of a radiation source.

Patent CA-2492580-A1 (CA)
Title: Capacitor dropping power supply with shunt switching
Inventor: ALLARD JOHN JOSEPH
IPC: H02M5/08
Filed: 2005-01-14
Abstract: A capacitor dropping power supply is disclosed wherein diode power dissipation is avoided due to the unique combination of the diode with the capacitive dropping power supply coupled with a silicon control rectifier ("SCR"). Thus, internal power dissipation is minimized when power is not needed by the load by shorting out the diode. This is accomplished in the form of a voltage regulator wherein a zener diode is used to turn on the SCR  when the output voltage exceeds a predetermined level. The SCR provides a shunt switching operation, shunting input current and providing a sufficient amount of power to supply the load and shorting out voltages above a set amount. As a result, there is a power savings when power is not being supplied to the load.

Title: Groupwise successive interference cancellation for block transmission with reception diversity
Inventor: ZEIRA ARIELA
IPC: H04B1/707
Filed: 2003-07-18
Abstract: A plurality of data signals are received over an antenna array having a plurality of antenna elements. The data singals are transmitted over a shared spectrum in a wireless communication system. A signal having each of the data signals is received over each antenna element. The plurality of data signals are grouped into a plurality of groups. The received signals of the antenna elements are matched filtered (70) for a first group of the plurality of groups, producing a matched filtered result. Data is jointly detected of the first group using the matched filtered result. An interference correction signal is constructed (76) using the detected data for each antenna element. The interference cancelled result is subtracted (92) from the received signal of each antenna element, producing an interference cancelled result for each antenna element. Data is successively detected for remaining groups using the interference cancelled result for each antenna element.
