Inventor: HIPP CHRISTIAN J
IPC: B41J3/54
Filed: 2000-05-04
Abstract: The effective life of a printhead, such as an ink jet printhead, is extended, when printing repetitive images, by taking measures to change the printhead print elements (e.g. nozzles) that are fired to effect repetitive imaging at a desired location on the media. The nozzles can be changed, yet the repetitive images be provided at the same desired location on the media by one or more of : finishing the media after printing to take into account a new position of the images on the media to provide a proper finished media (e.g. by trimming a particular edge or edges); at spaced points in time moving the printhead relative to the media in the second dimension (e.g. substantially transverse to the first dimension); and/or at spaced points in time moving the media in the second dimension relative to the printhead. Where the position of the printhead is moved, that may be accomplished by utilizing a detented shaft, controlled by a knob, that rotates a mounting shaft of the printhead and effects linear movement of the printhead. One detented movement of the detended shaft may correspond to a one pixel movement of the printhead.

Title: Receiver system using analog to digital conversion at radio frequency and method
Inventor: KAMINSKI WALTER JOSEPH
IPC: H04B1/26
Filed: 2001-02-22
Abstract: A receiver receives analog signals at radio frequency (RF), and the RF analog signals are converted into the digital domain. As such, the receiver does not require frequency conversion stage(s) prior to analog to digital conversion. For example, the receiver can comprise at least one antenna(s) which receives radio frequency (RF) analog signals at different frequency bands. The analog RF signals are provided to a single analog to digital (A/D) converter, and the A/D converter converts the analog RF signals at the different frequency bands into digital signals within the Nyquist bandwidth. By properly selecting the sampling rate of the A/D converter for the RF analog signals, the A/D converter can produce replicas of the different frequency bands of the analog signals in non-overlapping portions of the Nyquist bandwidth.

Patent CA-2340360-A1 (CA)
Inventor: BENNETT FRED
IPC: A01K97/01
Filed: 2000-06-09
Abstract: A fishing tip-up device is provided. A magnet holds a signaling device in a non-activated state. When an electronically operated sensor device senses movement of a fishing reel, a signal is sent to the magnet which causes the magnet to release the signaling device to indicate the occurrence of a possible fish strike. An annunciator turns on and off as a result of the sensing device sensing the rotation of the reel. The electrical circuit is activated when a fishing rod is properly positioned within a base frame of the fishing tip-up device. The electrical circuit is deactivated when the fishing rod is properly placed within the base frame for storage and transportation.  The fishing tip-up can be manipulated into a single compact unit which is convenient for storage and transportation. A fishing reel is provided which creates drag in the unreeling of the fishing line when a fish takes off with the bait, thereby inhibiting the fish from unreeling the entire line.

Title: Method for increasing the rate of article production by a stacked mold
Inventor: GAUL HARALD
IPC: B29C45/04
Filed: 1990-07-26
Abstract: An injection mold for use with a molding press has four mold levels in axially stacked relation, permitting a substantial doubling of output for a given size of press as compared with a back-to-back two level stacked mold. The mold feeder flow path extends axially from the injector head to a flow distribution block located at the centre of the stacked mold block series. The centrally located distribution block is connected, in use isolation, sealed relation with the injector head, being axially displaceable therefrom in contin-uing sealed relation upon the opening of the mold. A drool prevention valve system, located at two of the mold inter-faces, to preclude drooling of fluid plastic stock upon open-ing of the molds includes pressure fluid actuators for operat-ing the valves, wherein the pressure fluid may comprise the fluid plastic stock. The valve system also includes a de-pressurizing valve provision, wherein, upon opening of the mold interfaces the stock distribution passages are substan-tially depressurized, to thereby reduce any tendency to drool.      The mold includes axial adjustment means to compensate for differential variations in overall mold length within the press, due to changes in effective mold temperature.

Patent CA-2344844-A1 (CA)
Inventor: LAROIA RAJIV
IPC: H04W74/00
Filed: 2001-04-23
Abstract: In a wireless communication system, mobile unit and base station access request and page transmissions are addressed by employing an efficient unified approach for the transmission and detection of both access requests from a mobile unit and pages from a base station. To this end, a mobile unit monitors for access requests and monitors a prescribed resource to detect if a page has been received. Upon detection of an access request, a corresponding request message is generated and transmitting substantially immediately to a base station, thereby minimizing latency in the access process. Concurrently, a base station monitors to determine if a page indication has been received and monitors a prescribed resource to determine if an access request message has been received. In this process, the processing of request messages takes precedence over the processing of pages. Upon detecting a received request message a request response message is generated and transmitted substantially immediately to the mobile unit, thereby also minimizing latency in the access process.

Filed: 2001-09-10
Abstract: Techniques for black and white pattern rendering that increase processing speed and reduce memory requirements while providing improved pattern selection performance are provided. The hue angle and lightness of a color input are determined. The hue angle is used to index into a lookup table of halftone functions that specify default frequency and spot functions for a hue angle range. For each selected halftone, the determined hue angle is substituted from the hue angle range if the determined hue angle differs from the last determined hue angle range by more than a threshold difference value. The determined lightness is used to determine the halftoning threshold value and rendering then occurs.

Title: Graft versus host disease
Inventor: SPANER DAVID ELLIOTT
IPC: A61K35/12
Filed: 1999-07-30
Abstract: The development of graft versus host disease in a mammalian patient undergoi ng cell transplantation therapy for treatment of a bone marrow mediated disease , is prevented or alleviated by subjecting at least the T-cells of the allogeneic cell transplantation composition, extracorporeally, to oxidative stress, in appropriate dosage amounts, such as bubbling a gaseous mixture of  ozone and oxygen through a suspension of the T-cells. The process may also include irradiation of the cells with UV light, simultaneously with the application of the oxidative stress. The oxidative stress induces reduced inflammatory cytokine production and a reduced proliferative response in the  T- cells.
