Patent GB-2305036-A (GB)
Title: Reliable watchdog timer for microprocessor
Inventor: YU KUO-CHENG
IPC: G06F11/00
Filed: 1995-08-30
Abstract: A watchdog timer 3 resets the microprocessor 4 on line Y if the counter 32 is not cleared on line C before it has counted a given number of pulses X from clock oscillator 31. Clear signals C will only be generated by XOR gate 332 when the latch 3311 is alternately set and reset by signals S and R produced by the microprocessor 4. The D flip-flop 3312, which is clocked by the microprocessor 4 on line W, delays the latch output so that the XOR gate 332 can detect transitions in the latch state. The counter 32 may generate the reset signal Y when it overflows or when it reaches a count value preset by the user.

Title: Measurement of calorific value of a gas
Inventor: HAMMOND PAUL STEPHEN
IPC: G01N33/22
Filed: 1995-11-27
Abstract: An apparatus 4 is designed to measure the calorific value and/or Wobbe index of a fuel gas supplied along pipe 2 and comprises an electronic control 22 which can operate outlet valves 32 and 36 and cause inlet valve 20 to be locked in a closed position or unlock it until the gas pressure in a chamber 6, of predetermined volume, reaches a predetermined pressure difference above the pipe pressure. Under control 22, pump 18 pumps a sample of fuel gas from pipe 2 into the chamber 6 whilst valves 32 and 36 are closed. On the pressure in chamber 6 attaining the predetermined difference, the valve 20 is held closed and the speed of sound in the gas, and/or the thermal conductivity, and/or specific heat capacity are measured. Then valve 32 is opened and the gas discharges back to pipe 2 through an orifice plate 34 and conduits 12, 16. This allows the measurement of the gas density. The viscosity of the gas is similarly measured using a capillary passage 38 and conduits 14, 16 and the calorific value etc. is derived. <IMAGE>

Patent GB-2325318-A (GB)
Title: Processing information in a plurality of processing stages
Inventor: SNAPE TIMOTHY RICHARD
IPC: G06F9/44
Filed: 1998-03-20
Abstract: Processing digital information, such as image or audio information, using a data flow type architecture. Input data elements are sequentially processed by a plurality of nodes, 10, 2, 12, and at a final stage the processed data is output 12, to storage or for remote transmission. Each node is activated by means of one or more triggers. Each input-only node 10 or input-output node 2 can trigger one or more successive input-output or output-only nodes, thus enabling parallel processing. Also, a processing node may require more than one trigger to start processing, thus the results of previous processing stages can be combined. Other possible node triggers include self triggers which can be activated internally within a node and external (e.g. user-initiated) triggers. Buffer means (6, fig. 1) associated with the nodes store the processed data elements to prevent corruption by subsequent processing. Security and fire alarm applications are described (figs. 5 and 6).

Title: Collapsible pushchair/stroller with one-hand release latch
Inventor: KAKUDA BAKU
IPC: B62B9/20
Filed: 1998-07-06
Abstract: The pushchair 100 (Fig.1) includes a rotary moving member 114 (Fig.1) incorporated into a handle portion 106 (Fig.1) of a frame 102 (Fig.1). The moving member is connected to wires 206,208 (Fig.3A) that extend through a tube 204 (Fig.3A) to slidable latches 112 (Fig.1). The moving member includes two half shells 302,320 (Fig.3A) mounted via grooves 310,312,322,324 (Fig.3A) which engage pins 330,332 (Fig.3A) which protrude out of grooves 340,342 (Fig.3A) formed in the tube. In use, the moving member is rotated by an operator, such that the grooves slide the pins axially along the length of the shaft, i.e. rotational motion is converted into linear axial motion. When the pin moves along the axial length of the tube, the pins pull the wires along with them. The motion and force of the wire is used to release the latches 112 and collapse the stroller. The moving member may be constructed in a one-piece form (Fig.3B). To prevent inadvertent rotation of the moving portion and collapse of the stroller, a rotation lock (1000,Fig.10) may be used. The lock includes a resiliently biased nose portion (1002,Fig.10) formed on the moving member which cooperates with a recess (1006,Fig.10) on the lip (1020,Fig.10) of an end cap (350,Fig.10).

Title: A vertical interconnect package for electronic components
Inventor: HUTCHISON BRIAN R
IPC: H01L23/495
Filed: 1998-08-21
Abstract: A tripartite lead frame-based Vertical Interconnect Package (VIP) provides integrated feedthrough and integrated shielding in a non-ceramic package, particularly for high frequency applications. One frame 15 functions as the substrate for coupling an IC device 34, and a second lead frame 24 and third lead frame (40, fig 4) form shielding and feedthroughs, with the third lead frame also providing a lid whereby an airtight chamber around the IC device is formed. The VIP provides a ground button (the shortest path to the die) divided into n sections providing additional RF and separate ground paths; lead frame connections are used for DC. The leads of the first lead frame 15 may be encapsulated in plastics 29. In a modification the package includes five lead frames housing two IC devices. The lead frames are conductive, e.g. of copper. The VIP provides easy interfaces to the printed circuit board in surface mount technology manufacturing and is compatible with die mount technologies such as flip-chip.
Patent GB-2342204-A (GB)
Title: Fire alarm system
Inventor: PAYNE ROGER DENNIS
IPC: G08B25/04
Filed: 1998-09-30
Abstract: A fire detection and alarm system has fire detecting devices of different types and alarm means connected across supply lines. Both types of device normally apply a high impedance across the supply lines in a standby condition, and a low impedance in an alarm condition. The fire detecting devices are operable by a first voltage. This is lower than a second voltage applied, by a central control unit (CCU), to the lines in an alarm condition for operating the alarm means. The alarm means respond to operating current supplied under different conditions to give respectively different kinds of fire warnings. Each first and second type of fire detecting device has current limiting means for differently limiting the respective current drain on the supply lines in the alarm condition. The CCU is operable to cause the supply line voltage to be momentarily reduced below the second voltage, so that the alarm means is momentarily deactivated, whereby the CCU can then respond to the supply line voltage, due to the respective current drain of the current limiting means, so as to apply the operating current to the alarm means to give the required fire warning. This enables priority to be given to a manual call point.
