Title: Position detection of mechanical resonant scanner mirror
Inventor: MELVILLE CHARLES D
IPC: G02B26/10
Filed: 1997-09-18
Abstract: Two piezoelectric sensors (78, 80) are mounted on the back of a spring-plate (14) of a mechanical resonance scanner (10) on respective sides of a center line coinciding with an axis of rotation (16). As the scanner mirror (12) rotates back and forth the two sensors are accelerated and decelerated at a 180~ phase difference. Each sensor's output voltage crosses a zero level when the acceleration is unchanging. A differential amplifier (88) detects the zero-crossings for motion along the axis of rotation. Common mode rejection eliminates the non-rotational accelerations associated with external vibrations and shocks, and prevents masking the mirror's zero-crossings.

Filed: 1999-09-17
Abstract: A coaxial connector that comprises an attachment member and a compression sleeve. The attachment member includes a collar, which is coupled with a nut that is free to rotate about the collar, for receiving, at least partially, the compression sleeve therein. The collar has an internal shape of decreasing diameter for radially constricting the compression sleeve when inserted into the attachment member such that the coaxial connector may be sealed from environmental elements entering therein. This allows for a much smaller sized barb to be used on the end of a post within the attachment member, or no barb at all. The coaxial connector further includes a lip secured within the compression sleeve for preventing the braided shield from sliding between the compression sleeve and cable jacket during installation of the coaxial connector.
Patent CA-2284772-A1 (CA)
Inventor: AGRAWAL NITIN
IPC: G06F9/302
Filed: 1998-11-06
Abstract: A processor having a modified Harvard architecture having first and second memories (224 X, Y), an address register file divided into first and second sets of registers (216 X, Y), first and second stream registers (226 X, Y), and a general purpose register file (218) for performing data streaming. The first and second sets of registers respectively address the first and second memories which, in turn, load data into the first and second stream registers.  An arithmatic logic unit (ALU, 230) accepts the stream registers and general purpose registers as inputs. Stream instructions are encoded such that a single instruction specifies an ALU operation performed on selected ALU inputs and where to store the results of the ALU operation, loads new values into the stream registers, and updates the address registers. A stream instruction has three operand fields respectively specifying two operands for the next ALU  operation and a location to store the result of the current ALU operation. The bits in the fields for specifying a stream register and addressing mode are positionally overlapped with the bits for specifying a particular general purpose register. This encoding allows a simple instruction decoding mechanism while enabling parallel memory accesses and address update in a compact instruction.
