Title: Gain control and capacitance correction for photodiode signal amplifier
Inventor: HADLEY MAXWELL RICHARD
IPC: H04B10/43
Filed: 1994-03-08
Abstract: An amplifier circuit 1 is arranged to amplify a signal of variable magnitude from a photodiode 3 having capacitive characteristics. The circuit 1 comprises a first feedback path containing a voltage controlled variable resistor 8 for varying the gain of the amplifier in relation to the magnitude of the signal so as to provide an output signal of substantially uniform magnitude. The first feedback path also contains a capacitor 7 which compensates for adverse effects of reactance in the circuit caused by the capacitance of the photodiode 3 and of the variable resistor 8 in order to optimize the frequency response characteristics of the amplifier. A second feedback path comprising a fixed value resistor 9 becomes operable when the resistance of the first feedback path is large to provide fixed gain amplification of signals received from the photodiode 3. <IMAGE>

Title: HSYNC pulse synchronisation to local clock without a PLL
Inventor: MAEDER HEINZ BERNHARD
IPC: H04N5/12
Filed: 1996-02-01
Abstract: The frequency of a local high-frequency clock signal 10 is adjusted to match it to a multiple of an incoming horizontal sync. pulse signal 3. The frequencies of the local clock source 10 and the incoming horizontal sync. signal are compared 9 and the result 12 is applied to logic block 8 which selects 6, 7 a sequence (figure 4) of respectively delayed signals produced from the local clock source 10 by the auxiliary clock generator 4, which may be a Johnson ring counter. Hence the frequency of the output clock signal 2 may be increased or decreased with respect to the frequency of the auxiliary clock signals 5, so that no PLL is required to provide an output signal 2 with a frequency which is a multiple of the incoming signal 3.

Title: Automatically controlling a differential lock in drive axles of a motor vehicle
Inventor: DIEKHANS NORBERT
IPC: B60K23/04
Filed: 1997-05-23
Abstract: In apparatus and a method for automatically controlling a differential lock in drive axles of a motor vehicle, an engagement and a disengagement criterion for a locking clutch is established, which is dependent on the vehicle speed (4,5) and vehicle-specific geometry data and steering angles (6). In that way it is possible to determine a reference rotary speed value (11) for each wheel, wherein after comparison with a threshold value (15), a control signal (18) to effect automatic engagement and disengagement of the locking clutch is produced. The invention is for use in motor vehicles, in particular motor vehicles with all-wheel steering.

Title: Double sheet detector
Inventor: OWENS MARK
IPC: B65H7/12
Filed: 1997-09-09
Abstract: A bracket has two holes drilled at a distance so when fitted to a known electro mechanical detector there is a gap between the two wheels E, F of 0.05mm(+/- 0.01 mm). The lower hole is of larger than the diameter of the spindle it fits over, so that if a double sheet be fed through, the lower wheel will still lift to contact the upper wheel and therefore stop the machine. With the wheels being connected at a set distance, the detector can be adjusted with the lower wheel just touching the substrate passing below it, thus avoiding the spring pressure pushing the lower wheel into the substrate which can cause marking/spoilage.
