Title: Multipurpose lectern
Inventor: MATZDORFF WERNER
IPC: A47B19/06
Filed: 1998-07-09
Abstract: The invention concerns an improved lectern for presenting bound books, consisting in a device for receiving the open book with maximum security for its cover and optimal reading comfort. It consists of two plates (1) with a ledge (2) fixed by clamps (3) to pivoting pins (4). Said pins (4) are fixed on a crosspiece (5) whereof the upper profile constitutes a stop for the inclination (6) of the plates and houses springs (7) balancing said plates, a device (C) for extending the crosspiece (5). Said crosspiece (5) is fixed to lateral legs (8) by a system such as, for example, perforations and bolts (9) for varying the lectern inclination from a horizontal plane to a quasi-vertical plane. The legs (8) comprise recesses (10) for receiving a mobile crosspiece (11) or console (12), fixed on either a central (13) or lateral (14) column. In the latter case, the height is adjusted by means of a rack (15) or a clamp assembly (16). To ensure a proper limit stop for the edge (0) of the book pages on the plate ledge (2), the usual slight extra width of the cover (17) is compensated by mobile inserts (18) maintained above said extra width (17) by a fold-up forming a corner angle piece.

Abstract: Method and apparatus for performing data conversion between first-format encoded data in which orthogonal transform coefficients are arranged in an order of DC  components and AC components from a low spatial frequency order to a high spatial frequency order in each orthogonal transform block when compression encoding which includes orthogonal transform is applied to video data and second-format encoded data in which orthogonal transform coefficients are arranged in an order of DC components and AC components from a low spatial frequency order to a high spatial frequency order in each block assembly member formed of a plurality of orthogonal transform blocks when compression encoding which includes orthogonal transform is applied to video data. The second-format encoded data may be decoded to obtain orthogonal transform coefficients which may be re-arranged from a low spatial frequency order to a high spatial frequency order in each orthogonal transform block of the first format. Such orthogonal transform coefficients may be encoded to form encoded data having the first format.

Patent CA-2301293-A1 (CA)
Inventor: COSMAN MICHAEL A
IPC: G06T15/50
Filed: 2000-03-16
Abstract: A system and method for antialiasing bump texture and bump mapping which overcomes the disadvantages of previous methods of antialiasing bump maps without significantly expanding the required physical hardware needed for the calculations. A bump curvature value computed from the difference in heights between adjacent texels is applied to the specular shading calculations for bump maps. The bump curvature is used to open an "integration window" over the specular highlight of the bump. The resulting integral provides a highlight value which approximates the specular highlight.  The highlight value is then added to the pixel shading value in the frame buffer.  The process decreases the brightness of the highlights while increasing the overall brightness near the highlights, in a user-controlled blend that preserves the proper average effect of the specularity or reflectiveness. The process has no effect where there are no bumps or where the viewer is so close to the surface. Two user-supplied coefficients properly account for the content of the bump texture and the values of the surface materials coefficients.

Abstract: A streaming media control and synchronization application program interface (API) for a digital television receiver. The API provides a simple alternative to the Java Media Framework for JavaTV and other television software environments, including the Advanced Television Systems Committee Digital TV      Application Software Environment (ATSC T3/S17 DASE), and the Digital Video Broadcast Multimedia Home Platform (DVB MHP). This API enables playing back media, and controlling the playback. The API includes a media presentation control package, "MediaComponentPresenter," and a service presenter hierarchy. The API controls stopping, starting, suspending and resuming the presentation of the streaming audio and/or video at a media player, e.g., at a television set-top receiver. The API also provides a start method that attempts to synchronize the presentation of audio and/or video streams according to associated locators of the streams. The API also can take checkpoints of the audio and/or video as it is playing, where the checkpoints indicate temporal locations of the audio and/or video for initiating a rewind operation.

Patent CA-2306749-A1 (CA)
Title: Coin acceptor
Inventor: WOOD DENNIS
IPC: G07D5/00
Filed: 1998-10-30
Abstract: A coin acceptor includes sensor coil units (C1, C2, C3, C4) small enough to sense respective different regions of the face of a coin (8) as it moves past them, so as to produce time varying sensor outputs (x1(a), x2(a), x2(f), x3(a), x4(a)) as a function of the different regions. The sensor outputs are sampled repetitively. A microcontroller (11) monitors the sample values so as to determine when the value of at least one of the sensor outputs adopts a predetermined criterion, e.g. reaching a peak value and in response thereto, compares the value of the sensor output that includes the peak value with corresponding values stored in an EEPROM (12) to determine the acceptability of the coin.
Patent CA-2307490-A1 (CA)
Title: Control channel for time division multiple access systems
Inventor: KRISHNAMOORTHY RAJEEV
IPC: H04B1/7075
Filed: 2000-05-04
Abstract: In a TDMA system a multifunction control channel is employed that carries data used for implementing channel access functionality for users and is also employed at the remote terminals in the performance of modem functionality. In other words, information necessary to accurately receive data on the user traffic channels is obtainable by processing the multifunction control channel. This is achieved by arranging the broadband channel of the TDMA system as a repeating frame having time slots in which at least one time slot is reserved for use as the multifunction control channel, and the data that is transmitted on the multifunction control channel is encoded using a spread spectrum format. To this end the data carried on the multifunction control channel is encoded in a way that uses each symbol of the multifunction control channel as if it were a so-called spread spectrum "chip". At least one of the remaining time slots of the frame, and preferably all of the remaining time slots, which are typically used to carry user traffic arranged as logical channels, are not spread spectrum encoded. With regard to modem functionality, the remote terminals use the received multifunction control channel to a) perform frame synchronization, i.e., frame timing, b) perform frequency offset estimation, c) obtain an estimate of the channel impulse response, and d) estimate the received signal strength for use in gain control.
Patent CA-2308439-A1 (CA)
Title: Syringe pumps
Inventor: COBB ANTHONY RICHARD
IPC: A61M5/00
Filed: 2000-05-11
Abstract: Syringe pumps have a drive mechanism for moving the plunger of a syringe along a barrel. In the present invention, ears at the rear of the barrel engage against a wall on the pump and an L shape clamp arm is urged against the ears by a spring. The clamp arm is mounted about an axis at right-angles to the syringe and is articulated at a point along its length. A lever having a flag at one end is pivoted about a horizontal axis by movement of the arm and moves relative to an optical sensor so that the output of the sensor indicates whether the syringe is correctly loaded in the pump. The clamp arm is rotated away from the barrel by the drive mechanism during loading of the syringe.
