Patent DE-19742058-A1 (DE)
Title: Active pixel sensor cell operation method
Inventor: MERRILL RICHARD BILLINGS
IPC: H04N3/15
Filed: 1997-09-24
Abstract: The method involves resetting a sensor cell and reading the cell to determine the reset value. After resetting, the active pixel sensor cell is read a number of times to produce a number of corresponding read values and to determine whether the last read value of the set indicates saturation of the cell. The active pixel sensor cell is read a number of times after resetting and before it becomes saturated. If the last value indicates saturation, the last value before saturation is identified and a collected photon value derived.

Patent DE-19750933-A1 (DE)
Title: Readiness mode switching unit with low signal attenuation
Inventor: YAMAZAKI MASAO
IPC: H04B1/74
Filed: 1997-11-17
Abstract: The unit has a branching device connected to a normal receiver and a standby receiver, and consists of a coupler and a high frequency (HF) switching unit.

Patent DE-19808858-A1 (DE)
Title: Hand and forearm therapy appliance
Inventor: FRENKEL WOLF GERHARD
IPC: A61H15/00
Filed: 1998-03-03
Abstract: The interval between the two preferably soft or fleecy rollers (3,4a) of the appliance ensures that an inserted hand or forearm is compressed by the rollers between volar (palm) and dorsal (back) sides.   The top roller (3) is a wasted design as opposed to the bottom roller (4) which is barrel-shaped in longitudinal section so that with the rollers carried in parallel their exteriors are complementary to leave an upwards swept interval. A drive (5) rotates the two rollers in synchronism so the hand is drawn in by the bottom roller as the top roller strokes the rear of the hand in the direction of the heart. The drive provides torque to its two drive wheels via a gear with its adjustable rev. count stepped down via its small and large diameter meshing wheels. An opening (1a) in the top part of the housing (1) admits the hand between the rollers, using a heavy and stable housing bottom part (2). Inserting the hand trips the drive microswitch automatically, using slip coupling between drive and rollers which responds to preset roller pressure to cut out the rotation.
