Title: Microcomputer aided video still picture with accompanying audio                 distribution and trasmission method
Inventor: HUNTER IAN JAMES
IPC: H04N7/00
Filed: 1991-06-15
Abstract: A method enabling a television transmission program me contractor, transmitting via a network of terrestrial transmitters normally sharing common video feeds, to distribute to an individual transmitter within that network, an exclusive feed of video stills with accompanying audio. A sequence is transferred as digital information from the station computer at the contractor's premises, via a digital data link or via an addressed signal within the normal video feed, to a microcomputer at a transmitter site, where it is stored in the microcomputer's memory until it is required for transmission. Transmission is completed by sending signals by the same means, commanding the microcomputer first to prepare, and then to output the sequence to the transmitter, by operating the video and audio switch. This substitutes the output of still pictures and sound from the microcomputer for the normal video and audio feeds, for the duration of the sequence. <IMAGE>

Title: Ignition control circuit for the prevention of engine speed oscillations during load changes
Inventor: WILD ERNST
IPC: F02P5/15
Filed: 1992-02-12
Abstract: The engine speed is stabilised by identifying sudden changes in engine torque which would cause speed oscillations and changing the ignition timing to reduce these torque fluctuations. Measurements of engine speed, n, engine temperature, Tmot and engine load, tL, provide two families of characteristics 2, 5, (pre-determined by running the engine on a test bed and producing torque curves as a function of the above variables), to produce estimated values for the internal engine torque Mi and the frictional torque Mr, to produce an estimate of the effective torque Me by means of the subtraction circuit 4. This estimated torque value is passed through a low pass filter 12 to obtain a steady state value for the engine torque, Mesoll and the result is subtracted from the original estimated torque value, Me, to isolate any sudden changes in torque, AM, which is used as a measure of the torque change required to stabilise engine speed fluctuations. A division circuit 16 divides  DELTA M by Me to produce a value of the relative torque change, AMrel to which further torque reductions  DELTA M'rel may be added (e.g. for transmission control or drive slip control {ASR control}). This result is passed into a further low pass circuit 20 which is switchable to prevent sudden positive torque jumps. A further family of characteristics 23, having inputs of n and tL, produces a value for the ignition angle adjustment required. <IMAGE>

Abstract: A lighting load 18 can be turned on/off manually from one or more remote stations 34, 36 as well as from a master station 32, with control signals produced at remote stations 34, 36 being transmitted to master circuit 32 on a common conductor 30. The remote and master ON/OFF switches are of momentary contact type. A remote ON switch connects hot conductor 12 via a diode (D1), (Fig 2), to apply a positive signal to conductor 30, and a remote OFF switch connects ground conductor 16 via a diode (D2) to apply a negative signal to conductor 30 which is connected to an input (56) of a comparator (52), (54). The master circuit ON and OFF switches apply +Vcc and zero volts respectively to comparator input (56). Comparator (52), (54) applies set and reset inputs to a latch (60), (Fig 3), causing power switch SW1 to turn on and off respectively. The latch (60) also for reset inputs from a power on reset circuit (76) and an infra red motion detector 40. A master circuit power supply derives control circuit operating and reference voltages from the voltage drop across switch SW1. When the switch SW1 is off, a power supply capacitor (C3), (Fig 4), charges from hot conductor 12 via series connected resister (R8), capacitor (C2) and diode (D7). Setting of the latch (60) energises a relay (W) to connect the gate of switch SW1 to conductor 12 so that switch SW1 turns on. The relay also connects the primary of a step-up transformer (TX1) across switch SW1, the supply capacitor (C3) then charging from the transformer secondary. <IMAGE>
