Patent CA-2316378-A1 (CA)
Title: Digital and analog directional microphone
Inventor: KIKUTANI TADASHI
IPC: H04R3/00
Filed: 1998-12-21
Abstract: A directional microphone comprises a shotgun microphone (16) having an elongated tube which is designed to control directivity at frequencies above a predetermined frequency and at least four reference microphones (20, 22, 24, 26) spatially arranged about said shotgun microphone (16). A signal processor (50), which is electrically connected to the shotgun and reference microphones, generates interference cancelling signals (from 96) from the portions of the signals from the reference microphones (20, 22, 24, 26) which have frequencies generally below the predetermined frequency. The signal processor (50) combines (98) the cancelling signals with the signal from the shotgun microphone (16) to generate an output signal (100) in which signals originating from in front of the directional microphone in a direction along the longitudinal axis of the tube are enhanced and signals originating from locations other than in front of the directional microphone in a direction along the longitudinal axis of the tube are suppressed.

Title: Apparatus and method for improving computer memory speed and capacity
Inventor: KARABATSOS CHRIS
IPC: H05K1/00
Filed: 1999-06-22
Abstract: A method and apparatus for enhancing memory speed and capacity utilizes a se t of electronic switches (24) to isolate the computer data bus (2) from the memory chips (16, 32, 34, 36). The apparatus includes one or more multi-side s memory boards (10, 12, 14) with etched leads (30, 42), lands and feed-throug h. The memory chips may be mounted on either one side or both sides of each board. Connection between the memory board and the motherboard is made by means of a comb of contact fingers (5) or edge-connector which mates with a connector (8) on the motherboard (28). The data lines and address lines of t he computer bus are distinct from each other, and routed to the memory board vi a the edge connector (8). A set of CMOS TTL or FET switches (24) is located adjacent to the comb (5), and are switched on and off by a decoded combinati on of address, control, or data lines or by a distinct enable line provided by the CPU (3), controller or other decoding means located on the motherboard (28). As a result, only the memory chips actually required for the memory access are switched on, so that the other memory chips are isolated from the  data bus (2). Because of this isolation, the capacitance of the non-switched  components is not seen by the data bus, resulting in a lower overall capacitance, and a higher inherent memory access.

Inventor: BLOOM DAVID M
IPC: G02B5/18
Filed: 1999-06-18
Abstract: An apparatus and method for modulating an incident light beam for forming a two-dimensional projection image. The apparatus includes a plurality of elongated elements each having a reflective surface. These are suspended parallel to each other above a substrate with their respective ends supporte d, forming a column of adjacent reflecting surfaces grouped according to displa y elements. Alternate ones of each group are deformable by applying a voltage with respect to the substrate. An approximately flat center section of each deformed element is substantially parallel to and a predetermined distance from a center section of each undeformed element. A light beam incident to t he column of adjacent reflecting surfaces is reflected from a group of elongate d elements when the alternate ones are undeformed and diffracted when the alternate ones are deformed. A distance of movement is controlled or a ratio  of between reflection and diffraction periods determines a display intensity  for the corresponding display element.

Abstract: A tuned filter for connection to a busbar in a high voltage electric power system. The filter incorporates a variable inductor (2); the variable inductor (2) comprising a main winding (4), auxiliary windings (6-12) and switching means (14-20) associated with each auxiliary winding (6). The auxiliary windings are arranged to act in inductive series with respect to the main winding, and the switching means (14) are used to selectively connect the auxiliary windings in electrical series with the main winding, so allowing the inductance of the inductor to be varied. To achieve enhanced variability of the inductance (2), each auxiliary winding (6-12) has a number of turns substantially equal to x2 (n-l), where n is a positive integer corresponding to the position of each auxiliary winding in the inductive series (6-12) of auxiliary windings and x is also a positive integer. The switching means (14-20) are preferably constituted such that each auxiliary winding (6-12) is selectively connectable to the main winding (4) in any one of three connection modes, comprising a first connection mode in which the auxiliary winding assists the inductance of the main winding, a second connection mode in which the auxiliary winding opposes the inductance of the main winding and a third connection mode in which the auxiliary winding is bypassed with respect to the main winding.

Title: The surestop kit
Inventor: KIM CHANG HAN
IPC: B60B39/00
Filed: 2001-03-01
Abstract: The purpose of this invention is to improve the impediment of motion of the vehicle in icy/snawy conditions. In addition to this, it also allows for better traction by increasing, the amount of friction required to move the car (whether in a forward or backward motion) on slippery surfaces (i.e. ice/snow). This invention allows for better performance in an uphill or down hill climb of a vehicle in wintery conditions.      The Sure Stop Kit works by spraying a friction increasing substance (i.e. sand/gravel) thus allowing for better traction and stoppage power. It can be applied manually by a switch controlling the amount of substance released, or is done automatically through several sensors. There are advantages which are inherent in installing such a system in a vehicle such as increased weight in a vehicle for better winter driving, also the substance which has been released is recyclable and may be used by other drivers. The Sure Stop Kit is designed for universal use with varying sizes to accommodate the differences in models of vehicles. It is designed for either factory/stock installation, or after-market option. The Sure Stop Kit is refillable and comes in different options for economic purposes.
