Title: Video differential bus receiver using transconductance stage
Inventor: GURLEY THOMAS DAVID
IPC: H04N5/44
Filed: 1996-08-06
Abstract: A transconductance amplifier (30) provides a video output signal (S3) current directly proportional to the transconductance (gm) of the amplifier and to a difference between first (S1) and second (S2) differential video input signals supplies thereto. A pair (10,20) of buffer amplifiers couples the video input signals (S1,S2) to respective inputs (31,32) of the transconductance amplifier via respective diode switches (CR1,CR2) which provides Vber protection for the buffer transistors (Q1,Q2) and provides bus isolation under power down conditions. An output circuit (50) regulates the output voltage of the transconductance amplifier (30) at a substantially fixed voltage and converts the output signal current to an output signal voltage. Advantageously, the receiver provides very accurate signal gain control, unconditional stability, a wide common mode input voltage range, avoids the need for stand-by power and will not load the input bus under power-down conditions.

Title: Motor vehicle wheel anti-spin sprinkler
Inventor: ABBAS HATAM RADAM
IPC: B60B39/02
Filed: 1996-11-01
Abstract: A vehicle wheel anti-spin sprinkler comprises a standard windscreen combined washer pump 2 and bottle 1 containing water and anti-freeze mounted near the wheel-arch 6 of a motor-vehicle, and two flexible rubber tubes 7 with non-return valves 8 and each ending with a jet-nozzle 9 that direct the water/anti-freeze through a hole in the wheel-arch onto the front wheels at an angle. The pump is powered through leads 3 connected to the electrical system of the vehicle (12V) and is switched on by means of a switch 4 inside the vehicle. With slippery roads due to ice or sleet, free-spin can occur. This apparatus when switched on briefly will power the pump to deliver a squirt of water/anti-freeze mixture from the washer bottle through the rubber tubes to both front (or back) wheels, thus creating slush at the small area of wheel/ice contact. This increases the grip of the wheels and helps overcome free-spin.

IPC: H04N5/257
Filed: 1999-08-17
Abstract: A Light detector for a film scanning system is provided comprising at least first 14 and second 15 light sensitive regions. The first region 14 of the light detector is circular and surrounded by the annular second region 15. A spot of light is directed by an imaging lens 3 to illuminate the film 2. The light source can be a raster scan light source. Light transmitted by the film 2 is then directed by a collecting lens 16 to the light detector substantially to illuminate the first region 14. Light diffracted by imperfections in the film is received by the second area 15. The regions may be separate portions of a single sensor or separate sensors. The detector may comprise four separate regions wherein each region is a quadrant or a circle. Preferably the detector will have a diameter of 20mm to produce a signal four times greater than the normal 10mm detector without the same increase in noise. Each region is associated with an amplifier 20 and 22, the gain of each being variable with respect to the other by resistors 24 and 25. A signal processor is provided for receiving output signals from both regions and compensates the output of the first region with respect to the second. The signals are then summed to produce an electrical signal representative of the film. The apparatus may be used in a Telecine device.
