Title: Respiratory function monitor especially for very young children - employs differential amplifier for compensation of extraneous interference with breathing sounds filtered and recorded graphically.
Inventor: KLEMM BERND
IPC: A61B5/08
Filed: 1995-08-08
Abstract: The monitor is based on an acoustic waveguide (6) with apertures (9) in the vicinity of the patient's nostrils (8).

Title: Electromagnetic spring brake using magnet to close armature discs
Inventor: BUCK GERHARD
IPC: F16D59/02
Filed: 1996-04-16
Abstract: A plate (18) is permanently fixed to the inner armature disc (10) on the side facing the brake lining (8) and brake function tests make use of a handle which can be released and moved into its open setting onto inner or outer (11) armature discs against the closing force of the springs (12,13). An adaptor (19) on the radially outer end of the plate is traversed by a screw (21) itself anchored first in the magnet (14) and otherwise fitted with a head (22). A bridge piece (23) between screw head and adaptor produces a gap (24) used for the function testing. Function testing involves inserting the key with wide or narrow end into the gap. Tension is applied so the key covers or grasps the bridge over the test gap and thus clamps either inner or outer disc to the magnet to open and close the respective brake circuits.

Title: Amplitude fault correction for quadrature detector
Inventor: SHIMURA TAKASHI
IPC: H03D1/22
Filed: 1996-11-20
Abstract: The method involves using a detector comprising two multipliers, one for a reference signal and a measured signal, and the other one for an auxiliary reference signal and the measured signal.  The first multiplier transmits an I signal, while the second multiplier transmits a Q signal.  In the first correction step at least one of the two signals is measured.  In the second step the phases of signals, to be fed to the two multipliers, are changed such that an output signal with same or opposite phase relation to the Q signal is transmitted by a first integrator, while a second integrator transmits an output signal related to the I signal.  In the third step the signal relations are computed, and a correction coefficient is formed.

Patent DE-19654670-A1 (DE)
Title: Vehicle automatic transmission control method
Inventor: GIL SUNG-HONG
IPC: F16H61/20
Filed: 1996-12-28
Abstract: The vehicle transmission control arrangement includes sensors to monitor the selector setting as well as the speed of the vehicle e.g. during transmission creepage. The direction of creep is determined and control signals are generated to counteract any creepage in the reverse direction. The creepage is due to transmission drag as well as any inclines. If the vehicle is on an uphill slope, and has a tendency to roll back, the control activates the control elements of the transmission to provide sufficient forward drive to counteract the backward roll.
