Title: Vehicle communication system
Inventor: KOBAYASHI MASAYUKI
IPC: H04Q9/00
Filed: 1995-06-23
Abstract: An engine ECU (1), an AT ECU (2), a meter ECU (3) and an ABS ECU (4) are connected by a common communication line (5). The CPU (6) of the engine ECU computes various transmission data according to the detection results of sensors (12) and switches (13) and stores it in a memory (6a). The CPU reorders the transmission data in the memory in ID order according to a preset ID (identification data). The reordered transmission data is then sent to the communication control circuit (10) via a data transmission line (11). The transmission data is sent to the communication line according to transmission order. By sending the transmission data in the ID order, it is possible to minimize the transmission waiting time of high priority data. Moreover, if there is collision of different data on the communication line, the higher priority data is given priority in sending. <IMAGE>

Title: Pressure-sensitive copying sheets
Inventor: PARKER JOHN
IPC: B41M5/124
Filed: 1996-11-14
Abstract: A copying sheet (10) with a conventional CB coating (14) is enhanced by screen-printing at least a part with a discontinuous hot wax carbon coat (18). Marks (26,28) made therewith on a CF sheet (20) are thus patchworks of carbon-coloured areas (28) (which can be very dark) and carbonless-copy areas (26) (which tend to be pale). The carbon coat preferably has very fine patterning such that the copied marks are not visibly mettled but just seem darker than carbonless copy marks. Since the carbon coat is only partial, it is less "dirty" than a full coat. Its discontinuous nature also makes it difficult to read the mirror image of the copied message that tends to be left on the rear of carbon paper. The carbon coat can be applied in a hatched pattern that prevents information from being read through it. This may be useful in envelope construction.

Title: Checking the braking system of a vehicle
Inventor: UWE EISELE
IPC: B60T17/22
Filed: 1997-01-21
Abstract: Checking the braking system of a vehicle is effected by a method in which pressure is increased or reduced on at least one wheel brake by controlling electrical valves. Pressure is built up in at least one operating state, in particular before commencement of travel or during a stoppage e.g.at traffic lights when the brake is not actuated, for checking purposes and is then reduced again directly afterwards. The braking system is then checked via the pressure/time or force/time trend on at least one wheel brake, in particular to check whether there is an unallowable quantity of undissolved gas in the system. An unallowable quantity of gas will prevent effective manual braking in an emergency situation in which electrical control is lost.

Inventor: TAYLOR DOUGLAS ROBERT
IPC: H05B3/00
Filed: 1997-10-02
Abstract: A glass furnace or forehearth 1 has a plurality of electrodes 2a supplied with AC by a regulating transformer 3. In order to reduce the formation of bubbles by residual DC currents, the DC voltages at the electrodes are maintained at desired levels by injecting appropriate DC currents at selected locations. The voltage at electrode 2a is sensed and filtered 8 to form a DC component VE which is compared 9 with a desired voltage VR. The resulting difference controls a current source 10 which injects a current I into the electrode 2a. This procedure is carried out at a number of locations throughout the furnace. Each of the sensed voltages VE and injected currents I is transmitted in digital form to a microcontroller 12 which calculates appropriate values for the desired voltages VR, and also minimises the total injected current.
