Patent CA-2318666-A1 (CA)
Inventor: RAY JAMES C
IPC: B25B13/56
Filed: 2000-09-11
Abstract: A set of driver bits for Robertson screw fasteners includes driver bits (10a-d) whose shaft bodies (12a-d) have distinctive markings thereon corresponding to respective sizes of working tips (14a-d) of the driver bits. These distinctive markings are consistent throughout a family of sets. In one embodiment the distinctive marking are different colors, with each different color corresponding to a working-tip size. The colors are applied only to shaft bodies (36a-d) of som e of the driver bits by plating the shaft bodies with zinc layers (22) and then dying  the outer surfaces of the zinc layers with color dye (24). This coloring is carried ou t before the shaft bodies are connected to their respective working tips. Once the outer surfaces (20) of the shaft bodies are thusly colored, the respective working tips are  swaged to the shaft bodies to thereby form color-coded Robertson driver bits. In anoth er embodiment, the distinctive markings are surface-irregularity rings (32) extending about the elongated shafts, with the least number of rings corresponding to the smallest size working tip and the most number rings corresponding to the largest working tip.

Title: Differential pulse radar motion sensor
Inventor: MCEWAN THOMAS E
IPC: G01S13/18
Filed: 1999-03-12
Abstract: A pulse Doppler radar motion sensor system and method for sensing target motion within a gated region is provided with approximately constant response versus target distance. The sensor includes a transmitter (19) for transmitting a sequence of RF bursts comprised of a number of cycles at the transmitter frequency (12). The transmitted burst width alternates at a pattern frequency to provide a pattern of varying burst widths (14). The sensor includes a receiver (20) responsive to the transmitted bursts and burst echoes from moving targets within its sensing field. The receiver (20) produces a pattern frequency with a signal amplitude (25) representative of the difference in moving target response for two different range gated regions defined by the transmitted burst widths. The difference is detected to provide a range invariant target motion response in a sharply defined region. Another mode provides a quadrature receive channel for target direction determination.  Yet another mode time sequences the transmitted bursts to provide multiple range cell operation.

Inventor: FISCHER ROBERT
IPC: H04L27/26
Filed: 1998-04-14
Abstract: A method of performing an echo phase offset correction in a multi-carrier demodulation system involves the step of differential phase decoding phase shifts based on a phase difference between simultaneous carriers having different frequencies. An echo phase offset is determined for each decoded phase shift by eliminating phase shift uncertainties related to the transmitted information from the decoded phase shift. The echo phase offsets are averaged in order to generate an averaged offset. Finally, each decoded phase shift is corrected based on the averaged offset.

Title: Method and system for monitoring broadband quality of services
Inventor: CHEN THOMAS M
IPC: G08C15/00
Filed: 1999-06-03
Abstract: A method and system for monitoring a first virtual circuit in an asynchronous transmission mode (ATM) network comprises the steps of establishing in the network a second virtual circuit with the same path and QoS parameters as the first virtual circuit, and monitoring the first virtual circuit by determining the QoS parameters of the second virtual circuit. Specifically, a monitoring station (100A, 100B) determines the QoS parameters of the second virtual circuit by inserting monitoring information in cells transmitted and received on the second virtual circuit. The monitoring station (100A, 100B) inserts the monitoring information immediately before transmitting each cell and immediately after receiving each cell. Furthermore, the monitoring station (100A, 100B) compares the QoS parameters of the second virtual circuit with the QoS parameters of the first virtual circuit to determine network alarm information.

IPC: C01G45/02
Filed: 1999-11-08
Abstract: Manganese oxide particles and lithium manganese oxide particles have been produced with an average diameter less than about 500 nm. The particles have a high degree of uniformity including a very narrow distribution of particles sizes. Methods are described for producing metal oxides by performing a reaction with an aerosol including a metal precursor. In particular, the particles can be formed by laser pyrolysis. The lithium manganese oxide particles can be formed by the heat treatment of nanoparticles of manganese oxide. Alternatively, lithium manganese oxide particles can be formed directly by laser pyrolysis. The lithium manganese oxide particles are useful as active materials in the positive electrodes of lithium based batteries. Improved batteries result from the use of the uniform nanoscale lithium manganese oxide particles.

Title: Slot machine reel mechanism with dedicated local microcontroller
Inventor: LOOSE TIMOTHY C
IPC: G07F17/34
Filed: 2001-07-13
Abstract: A slot machine comprises a central processing unit (CPU) and a reel mechanism. The CPU operates the slot machine and randomly determines a game outcome in response to a wager. The reel mechanism includes a motor, a symbol-bearing reel, and a reel driver. The motor includes a rotatable shaft, and the reel is mounted to the shaft. The reel driver includes a local microcontroller distinct from and coupled to the CPU. The reel driver is coupled to the motor to cause the motor to rotate the reel. The CPU issues high-level commands to the reel driver related to rotation of the reel. The high-level commands may, for example, include a start spin command for starting rotation of the reel and a stop command for stopping the reel at a specified position. However, to free up the CPU for other tasks, the local microcontroller performs low-level reel driver operations related to the rotation of the reel. The low-level reel driver operations may, for example, include sampling a state of the reel in real time, performing calculations, and responding with control changes.
