Patent EP-0342507-A3 (EP)
IPC: H04M19/00
Filed: 1989-05-10
Abstract: Devices fed with operating voltage and optionally additionally with additional voltage are monitored for the presence of the voltage(s) required in each case. Additional voltage is supplied via plug-in connection and causes the storage of the requirement for the additional voltage in a storage device fed with operating voltage, which can only be cleared by totally disconnecting the operating voltage, but not by detaching the plug-in connection. With storage of the requirement for the additional voltage, alarm signals are given due to a failure of the latter. <IMAGE>

Title: Synchronisation of digital audio signals
IPC: H04L7/00
Filed: 1991-03-27
Abstract: A digital audio signal which is subject to sample-to-sample jitter is synchronised with local reference pulses (READ) by the use of a read-write buffer memory (12). Timing pulses (80) are associated with the input samples. The input samples are applied through a one-sample latch store (36) to the main memory, and the timing pulses are applied by switches (66,68) either directly or a short delay (38) to the write control input of the main memory. A phase comparator (24; Fig. 3) detects sample-by-sample when the write pulses are near to the read pulses and causes the switches to change state in response thereto, and they retain their changed state until a danger of potential read-write contention is again detected when they revert to their original state. <IMAGE>

Title: Angioplasty light guide catheter for stenosis ablation by means of laser energy
IPC: A61B18/24
Filed: 1991-03-04
Abstract: The angioplasty light guide catheter has a dilatation balloon (1) which is to be introduced into the vessel to be treated. The inside of the balloon is connected via a shaft to a suction and forcing pump and can therefore be regulated precisely in diameter. Light guides (6) extend over the entire length of the shaft and are coupled to a laser device via a connection piece at the proximal end of the catheter. At the distal end the light guides are embedded in the wall of the dilatation balloon (1). For stenosis ablation using laser light energy, the outlet points of the light guides can be moved radially outwards and inwards by changing the pressure in the dilatation balloon. The distance of the outlet points (6a) from the centre line of the balloon is thus a function of the pressure of the balloon fluid. This distance can thus be altered and controlled in a simple manner.
