Title: Integrated circuit phase-locked loop charge pump
Inventor: BALISTRERI EMANUELE
IPC: H03L7/089
Filed: 2000-06-21
Abstract: A charge pump (2) is supplied to reset in rated conditions the error signal of a phase-locked loop of the type whereby a phase detector (1) periodically supplies this pump (2) with a first and second impulse having emission instants dependent on the phase ratio between phase-locked loop input signals and are allocated to control circuit output increase or decrease respectively by means of ring filter (3a, 3b). The pump features loops (21, 22, 23, 24, 28) to transform the first and second impulse into a first and second voltage signal of longer duration than maximum impulse duration and featuring values the difference of which depends on the phase ratio between the loop input signals and to generate a signal in a current representative of such difference.

Patent CA-2314563-A1 (CA)
Inventor: KOCH WILLY
IPC: G03B27/62
Filed: 2000-07-20
Abstract: The photoelectric scanning device for original images contained on a photographic film has a film platform for the film, for temporarily holding the original images contained on the film in a respectively defined scanning position; a light source for illuminating the respective original image in the scanning position; a photoelectric converter for receiving light being transmitted through the respective original image in the scanning position, and for converting the received light into electrical scanning signals in a two-dimensional and pixel-by-pixel manner; an optical member for imaging the respective original image in the scanning position onto the photoelectric converter; and an electronic member for controlling the photoelectric converter and for reading out the electrical scanning signals which are generated by said photoelectric converter. A film notching device is disposed at the film platform in the region of the scanning position for punching or stamping a positioning notch into the side margin of the film at a location associated with the original image respectively in the scanning position. The integration of the film notching device directly into the scanning device requires only one positioning process of the films or the images contained on the films. Thus, the required apparatus cost and the technical control needed for the positioning are substantially reduced when compared to separate scanning and notching devices. Furthermore, the scanning device thus requires substantially less room than two separate devices, which is particularly significant when arranging the device within a copier device.

Abstract: This invention relates to a system for interactive on-demand delivery of multimedia using a multicast broadband backbone network transmitting IP-configured digital multimedia (e.g. television) signals. More particularly the on-demand system provides, inter alia, a Virtual Digital Video Recorder functionality. A system manager provides interactive access to the multimedia signals by a subscriber through either a decoder in a set top box (connected to a television) or a decoder in a computer (connected to a monitor) configured for converting the IP format signal into a format for display on the television or monitor. A central multimedia storage means is located within the network and remote from the subscriber for storing multimedia content. An on-demand component is configured for receiving a deliver request from a subscriber for the stored content, for locating the requested multimedia content from the storage means and for delivering the requested multimedia content for display on the television or monitor. The multimedia content is stored in the storage means in a format configured for locating same in response to a deliver request. An interactive program guide (IPG) may provide access to the multimedia signals and the multimedia signals are transmitted through the network according to scheduling corresponding to the interactive program guide. The on-demand component receives a record request (which includes broadcast channel and time information identifying the multimedia content and may utilize the IPG) from a subscriber and stores the multimedia content in response to the record request.

Abstract: An apparatus, program product and method dynamically adjust the scroll rate used to scroll through the program information for various television programs available to a television viewer to provide a variable rate of scroll for program information presented to the television viewer. The scroll rate may be varied, for example, to emphasize certain program information relative to other program information, e.g., by slowing down the scroll rate to increase the visibility for important program information and speeding up the scroll rate to decrease the visibility of less important program information. Dynamic scroll rate adjustment may be utilized in a number of situations, including in connection with non-interactive electronic program listings, interactive electronic program guides, and electronic overlays, among others. Furthermore, dynamic scroll rate adjustment may be based upon a number of different characteristics of the television programs associated with the displayed program information, including for example, the frequency of access of different television programs, or sponsorship of certain television programs.

Inventor: CORLESS ANTHONY ROBERT
IPC: G01N35/00
Filed: 1999-05-04
Abstract: An apparatus for locating a plurality of articles for laser marking comprising a support plate (16) having a plurality of apertures (18) extending from a first surface of the plate (15) to a second surface of the plate (17). The apertures are dimensioned to receive said articles (12) at the first surface of the plate (15), so that the at least a portion of the article is exposed through the aperture (18). Preferably apertures are defined by tapering walls. In use a laser (30) is directed towards a protruding portion of the article (21). The extent to which the articles protrude through the aperture (18) is significantly less than the variation in diameter of articles (12) to be laser marked. This eliminates the need for the laser to focus on individual articles (12).

Title: Absorbent material and method of production
Inventor: STEER GRAHAM E
IPC: C08L101/14
Filed: 2001-04-05
Abstract: A superabsorbent formulation is described for absorbing liquids (for example in an ostomy, incontinence or woundcare application), the formulation comprising superabsorbent (100 pbw), silica (3-20 pbw), water (0.5-8 pbw) and glycerol (5-40 pbw). The superabsorbent and silica are mixed together in a first production stage (10), to coat the superabsorbent particles with silica.

Abstract: Vertices of an annotation are projected onto a surface of a (2D or 3D) model and reconnected to preserve the original appearance of the annotation. The result of our method is a new set of geometry for the annotation that geometrically conforms to the surface of the model. A plane is defined by the midpoint of the original line segment and the two projected vertices. This plane is used to create the new line segments that conform to the surface, e.g. by doing a "surface walk" between the projected points along the line defined by the intersection of the plane and the surface.

IPC: F02D41/00
Filed: 2002-01-02
Abstract: The present invention provides a method and system for purging a vapor canister in a Hybrid Electric Vehicle during vehicle idle conditions. The present invention first determines whether purging is necessary by measuring fuel tank pressure and the time since the last purge. If either of these elements exceeds a calibratable threshold, the controller determines that the engine needs to be on and that purging must occur. An electronic throttle controller can also be used to command the throttle plate to low positions to increase intake manifold vacuum while purging. This allows for very rapid ingestion of the fuel vapor without risk of engine stalls, if used in an HEV where the engine speed is controlled by an electric motor. Upon completion of the purging process, the engine is shut "off" and the vehicle is returned to its normal idle conditions.  18
