Inventor: KIM JUNG SIK
IPC: H04Q7/00
Filed: 1997-09-22
Abstract: A simplified base-band interleaver with reduced memory requirements is described. A modulo-16 circuit (10) receives in series a plurality of indexes 0 to 383 and provides the remainder of the division of the index by 16. A bit invertor (12) bit inverts the output from the modulo-16 circuit (10) to provide a first column position. A quotient-16 circuit (16) provides the quotient of the division of the index by 16 and a code converter (18) having a row table maps the quotient to a first row position. A first counter (22) receives and counts a data read clock modulo-24 to provide a second row position and a second counter (20) counts a carry of the first counter modulo-16 to provide a second column position. A memory (14) includes a data interleaving table of at least 24 rows and 16 columns and data is written to the data interleaving table at the first row and column positions and read from it at the second row and column positions.

Inventor: POLACEK RICHARD R
IPC: B66B9/00
Filed: 1997-11-12
Abstract: An elevator system comprises an elevator frame 43 vertically movable in a hoistway 43H, a cab 13 mounted on a wheeled carriage 15 and a wheeled bogey 28 adapted to move along tracks 29 on a landing 36. A pair of rails 40 are mounted on the elevator frame to extend substantially across the hoistway, the rails spaced to cooperate with the wheeled carriage. A similar pair of rails 26 having the same spacing are mounted on the bogey. The wheeled carriage has a pair of wheels 20 at each corner. The ends of the rails are scarfed(127, Fig. 2; 132, Fig. 3) in a complementary fashion so as to provide a temporary half-lap joint between the rails of the bogey 26 and the rails of the elevator frame 40 when the two are aligned adjacent one another. This provides a continuous surface for the wheeled carriage to travel over, the spacing between the wheels 16, 17 of each pair of wheels being such that one or other of the wheels will be on a full section of rail at all times. Additional preferred features are urethane coated wheels, tapers at the ends of the rails and guide rollers (86-89, Fig. 4) on the carriage having vertical axes adapted to roll against an inside vertical face of each rail.

Title: Throttle valve for an internal combustion engine
Inventor: KALEBJIAN CHRISTOPHER JOSEPH
IPC: F02D9/10
Filed: 1997-12-31
Abstract: A throttle valve for an internal combustion engine includes a body (12) having a throttle bore (14) defining an axis (16). A throttle plate (26) is moulded within the throttle bore (14), thereby providing a relatively exact throttle plate to throttle bore positional relationship. The throttle plate (26) may be integrally moulded within the throttle bore (14) and attached to the throttle body (12). The throttle plate (26) is subsequently detached from the throttle body (12) for relative rotation within the throttle bore. To facilitate detaching of the throttle plate (26), the plate may be weakened about is periphery (34, figure 3). The throttle plate may be also formed with a bend for reducing throttle plate sticking upon rotation from an idle position and for controlling air leakage when the throttle plate is in the idle position. Further, the throttle plate (26) may include a wedge (50, figure 5) to control air flow through the throttle bore (14) and reinforcing ribs (62, figure 10) to further control the deflection of the throttle plate.

Title: A borehole measuring system employing electromagnetic wave propagation
Inventor: THOMPSON LARRY W
IPC: G01V3/30
Filed: 1995-03-07
Abstract: This invention is directed towards the determination of geophysical parameters of earth formations penetrated by a borehole. The invention is more particularly directed to determining and correcting for the effect of mutual coupling between receiver antennae located on the borehole logging instrument. A numerically controlled oscillator causes, via closed switch s4, an antenna 211, which is normally used as a receiver for logging, to transmit a wave at a first frequency. This is received at a second antenna 213 and passed via switch s1 in position 1 to a receiver circuit 507 which measures relative phase and amplitude compared to the transmitted signal, the results are recorded in digital processor 221. At the same time the amount of transmission signal reflected from the first antenna is passed via coupler 501 and switch s3 to a second receiver circuit 505 and thus to processor 221. From these measurements, the effects of mutual coupling between the antennae can be determined and used to correct actual logging measurements. The process can be repeated at other frequencies and in the reverse direction by altering the various switch positions.

Title: Method of digital colour inkjet printing on a non-absorbent substrate using ultraviolet curable inks
Inventor: TOURLE SIMON JOHN
IPC: B41M7/00
Filed: 1998-06-12
Abstract: A printhead 11 ejects jets 12 of ultraviolet curable inks towards an untreated substrate 15 made from a non-absorbent material such as a clear gloss or textured plastic sheet. The substrate is held on a drum 14 which rotates to expose the substrate to an ultraviolet light source 16 to cure the ink on the substrate. Each time the substrate passes beneath the printhead, ink of a different colour is ejected onto the substrate. The substrate is subsequently exposed to the ultraviolet light on each drum rotation to ensure the ink is cured before the next colour is applied. The substrate may be removed from the drum and exposed to a second curing source (10,Fig.1) if necessary to ensure the ink is permanently fixed on the substrate. The method may be used in, for example, a direct digital colour print process.

Title: Selecting region of interest in renal scintigraphy
Inventor: TOMARU YUMI
IPC: G06T1/00
Filed: 1998-07-01
Abstract: To assist in calculation of radiopharmaceutical uptake, a gamma camera image of a renal area is displayed on a computer. An operator then "clicks" on a pixel of the image at or near the centre of the image of the kidney. A first area around the pixel is automatically selected, and a maximum count within this area is used to calculate a threshold which is then used to select pixels within a second area around the central pixel to form a central renal area. If there is continuity between two parts of this central area due to a single pixel, this pixel is disregarded, and only the part of the area containing the original central pixel is taken as the renal central area. Finally, a peripheral area is determined either as a region of predetermined width around the central area or by using a second threshold, and the central and peripheral areas are added together to define the region of interest.

Title: Ring network formed from stackable units with self configuration system based on port connection status
Inventor: BYHAM CHRISTOPHER
IPC: H04L12/437
Filed: 1999-05-12
Abstract: A stackable network hub unit comprises 'up' <B>12</B> and 'down' <B>11</B> ports with data paths <B>14,15</B> between them. Means are provided at each port to detect the presence of a link to another stackable unit and the type of link. If no unit is detected the port is bypassed and data packets are directed from one data path to the other, as per <B>UNITS 1</B> and <B>3</B>, and the ring network is thereby formed. A 'resilient' cable may be connected between the 'up' port of the top unit and the 'down' port of the bottom unit on the stack (Fig. 4) to allow a bidirectional ring to be formed, that can operate with one link of unit out of service. The network units contain configuring means which transmit configuration packets containing source unit identification and its 'down' port connection status data, ie. normal connection, resilient cable or no connection. A unit receiving the packet compares this 'down' port status data with its own 'down' port status according to the table. If it wins it transmits a new configuration packet with its own identifier and port status, if not it forwards the packet it received. When a unit receives a packet with its own identification it becomes the bottom of the stack and other units are numbered therefrom. This scheme allows hot configuration of the stack and can accommodate hub unit failure and incorrect use of connection cables.

Title: Distributed circuit switched radio telecommunication network
Inventor: CHANDLER STEPHEN ANTHONY GERAR
IPC: H04B7/26
Filed: 1996-09-27
Abstract: A radio telecommunications network has randomly distributed fixed transceiver stations 20, 21, S, D each provided with switching circuitry for routing of calls between stations and utilizing other stations in the network for relaying such calls when necessary. Where mobile transceivers are to be used in the network, each mobile is associated with a particular fixed station acting as a base station. The mobile periodically transmits registration packets which are relayed to its base and which include information identifying the first station in the relay link, whereby the base knows the approximate location of the mobile. Each station 20 incorporates a call routing control unit to select a further station 21 to which a call from a source S to a destination D is to be transmitted for relaying the call. The routing control in a station transmits an interrogation signal to all other stations within range of that station, and such other stations transmit an acknowledgement signal after a delay indicative of the suitability of the station for relaying the call towards its intended destination. That station with the shortest delay is then selected. The delay may be indicative of the distance of the station from the call destination D. If further routing of a call from a station is blocked, eg. by an obstacle (26, Fig.4), the routing procedure backtracks one step and when other stations become aware of this, the delays are chosen such that a route bypassing the obstacle is set up. Gaps during speech or data transmission are indicated at a station by receiving a null speech packet (35, Figs.6,7). If an interrupt packet is received at a station during such a gap, a relayed call can be re-routed and that station can then act as a or destination D or source for a call from thereto or therefrom. A transmit carrier in a transceiver may be generated by means of an oscillator (51, Fig.9) and a divider (50), the divider being turned off on switching from transmit to receive to prevent interference with the receiver part which operates on the same frequency. A transversal filter (70, Fig.10) in a transmit circuit may be used to convolve a stream of impulses representing a data sequence with individual symbol waveforms to produce a combined waveform (60, Fig. 10a) having transmitter ramp up and down portions (65, 66) of limited duration. In a receiver circuit (Fig. 12) clock signal timing may be based on phase adjustment rather than a zero crossing technique, and means are also provided for offset error compensation and gain compensation.
