Patent CA-2516492-A1 (CA)
Title: Efficient automatic repeat request methods and apparatus
Inventor: LI JUNYI
IPC: H04W28/04
Filed: 2004-02-18
Abstract: Different NAK signals are used to indicate different relative levels of success in regard to an unsuccessful attempt to decode a received signal. An ACK signal is used in the case of successful decoding. The device which generated and transmitted the original encoded signal receives the NAK signal and selects a portion of redundant information, e.g., additional error correction bits, to be transmitted based on the value of the NAK signal. If the NAK signal indicates a low level of decoding success indicating a relatively large number of errors in the decoded signal, a large set of redundant information is selected and transmitted. If the NAK signal indicates a relatively successful decoding, e.g., relatively few errors, a small set of redundant information is selected and transmitted. Where a small set of redundant information is transmitted new information can be transmitted with the redundant information.

IPC: H01H83/00
Filed: 2006-06-08
Abstract: An arc fault circuit breaker includes line and load terminals, separabl e contacts electrically connected between the terminals, a current sensor adapted to sense current associated with a load and flowing between the terminals and through the separable contacts. An arc fault detection circuit provides series arc protection and generates a trip signal responsive to the sensed current. The arc fault detection circuit collects a plurality of samples of the sensed current over plural li ne cycles, determines that the load is a dimmer-controlled load, determines a phase ang le at which the sensed current begins conduction within one of the line cycles, an d determines that the phase angle consistently moves in a forward direction or a reverse direction. If so, then series arc protection is responsively inhibited. An operating mechanism opens the separable contacts responsive to the trip signal.</SDOAB >

Title: Titanium dioxide scouring media and method of production
Inventor: WOOLFOLK WILLIAM SCOTT
IPC: C01G23/047
Filed: 2005-04-29
Abstract: Round and spherical titanium dioxide scouring media and a method for producing the media are disclosed. The scouring media is effective in removing titanium dioxide buildup on the walls of a titanium dioxide reaction vessel. The method consists of forming green titanium dioxide pellets in a high intensity mixer by mixing commercially available titanium dioxide dust, water and a surfactant. The high intensity mixer produces substantially round, and spherical green pellets which are subsequently sized and sintered in a kiln to form round and spherical titanium dioxide sintered pellets that are suitable as a scouring media. The high intensity mixer allows the operator to closely control the size and shape of the pellets during the forming process to produce substantially round and spherical green pellets. Because the sintered titanium dioxide pellets are substantially round and spherical in shape, they are much less abrasive to the walls of the reaction vessel. Furthermore, as the pellets themselves abrade away, they do not contaminate the titanium dioxide product, and they can even be reprocessed into round and spherical scouring media.
