Title: Rolling shutter door with control device
Inventor: RIEDER HELMUT
IPC: E06B9/88
Filed: 1993-04-21
Abstract: The disadvantage with the known rolling shutter doors with a flexible shutter and a bottom termination border which, in the closed position of the rolling shutter door, rests closely against a floor surface is that, in the event of disruption, the automatic operation is interrupted and essentially manual re-starting has to take place. The rolling shutter door according to the invention avoids this disadvantage in that provision is made for a control device with a sensor (14) which detects a deflection of the door leaf with respect to the guide rails (8, 9) of the rolling shutter door. At the same time, the sensor (14) serves for the automatic compensation of the rolling-shutter-door position after the rolling shutter door has been re-started following disruption. Rolling shutter doors of this type are preferably used in industrial buildings for closing off through-passages or exterior door openings.   <IMAGE>

Title: Application of sec. audio signal for noise suppression in prim. audio signal - filtering sec. signal according to set of coeffts. to generate determined noise signal
Inventor: YOSHIDA TATSUMASA
IPC: G10L21/0208
Filed: 1993-06-03
Abstract: The process is used for suppression of noise and/or interference from a primary audio signal. The secondary audio signal is filtered according to a set of coeffts. such that a determined noise signal (Sn*) is generated. The latter is subtracted from the primary audio signal to generate a fault signal (Se) as an audio output signal. The power level of the primary or secondary audio signal is monitored to generate a control signal (CK), assuming an active, or non-active, state according to the level change. According to the fault signal, the coeffts. are brought up to date, with the control signal at its inactive state, while in its active state the coeffts. are kept constant. USE/ADVANTAGE - For hands-free car radio-telephone operation, with automatic matching of noise suppression to background conditions.
Patent DE-4325405-A1 (DE)
Title: Circuit arrangement for saving data in communication switching systems
Inventor: FRITZ NORBERT
IPC: H04Q3/545
Filed: 1993-07-29
Abstract: When the power supply of a switching system fails, all data necessary for the operation are to be saved so that they are immediately available again when the operation is restarted. For this purpose, it should not be necessary to hold any additional mechanically driven information carriers in readiness. For this purpose, an electrically programmable flash-type read-only memory is connected to an address bus and to a data bus to which the control is also connected. When the power supply fails, all data are re-stored, during a period in which residual energy is still available, from a data memory into the flash-type read-only memory which maintains its content even when the power supply fails. When the supply voltage returns, all data from the flash-type read-only memory pass back into the data memory of the switching system. Using the flash-type read-only memory and the connection and operating conditions provides an inexpensive space-saving arrangement for saving switching data.
