Abstract: A radio-updated timetable clock (1) with electromechanical scanning device (21) for outputting a switch-on signal (22, 22'), when the current timing information (5) checked by radio has reached the signal output time specified by the alarm time pointer (27), is to be designed for radio-accurate triggering of the alarm signal (24) even though the switching tolerance (30) of the scanning device (21), due to its function, has a relatively long and fluctuating response tolerance and without having to use digital comparator circuits as in the case where a signal time is digitally input. For this purpose, the alarm time setting is mounted so as to lead ahead of the angular position of the pointer mechanism in such a manner that the sampling time (31) including its complete switching tolerance (30) is located before the actual time (31') for outputting the alarm signal (24). Because of the long switch-on holding time of the switch-on signal (22) output by the scanning device (21), the condition of coincidence for outputting the alarm signal (24) accurate to a second occurs with the release time (31') checked by radio. When provision is made that the signal output times (31') can only be selected within a pattern (33) which is wider than the response switching tolerance (30) of the scanning device (21), it is ensured at the same time that no alarm coincidence can occur during this switching tolerance (30). <IMAGE>

IPC: H03K17/082
Filed: 1991-05-14
Abstract: A method and apparatus for protecting thyristors, particularly those in a power converter, from overvoltages. Voltage detectors determine if the forward voltage of the thyristors has increased above a predetermined level. If such an overvoltage occurs during a predetermined period after the conduction of the thyristor, forced triggering of the thyristor prevents damage to the thyristor. If more than one thyristor is employed, all the thyristors are forced triggered.

Abstract: A guidewire for use in guiding a catheter is provided with an expandable element at its distal region. The element may be expanded from a contracted configuration having a diameter corresponding to that of the guidewire and an expanded configuration larger than that diameter. A control element, such as a pull wire, extends through the guidewire from the proximal end of the guidewire and is associated with the expandable element to control expansion and contraction of the expandable element. The guidewire may be used in a number of modes. In one mode, the guidewire may be used to enhance the pushability of a catheter by locating the expandable element in the distal end of the lumen of the catheter and expanding the element at that location to lock the expandable element to the distal end of the catheter. Thereafter, the guidewire and catheter may be advanced in unison with the guidewire enhancing the pushability of the combination. In another mode of operation, the guidewire may be used with a single lumen balloon catheter in which the expandable element may be used both to enhance the pushability of the combination as well as to seal the distal end of the catheter to enable the balloon to be inflated and deflated through the catheter lumen.

Abstract: A method is described for monitoring a brake system which is equipped with an antilock and/or drive slip control system. The distance, the speed and the acceleration of the piston (45) of the master cylinder (56) are detected by a sensor (64). The brake actuation data thus determined are relayed in the form of electrical signals to the electronic governor (66). By means of a wheel sensor (67) the wheel data are relayed to the governor (66) in the form of electrical signals. The governor analyses whether the wheel data represent a correlation to the brake actuation data corresponding to correct braking. If this is not the case a switch (59) is operated. As a result of this current is fed to the electric motor. The motor (58) drives the pump (53). The pump delivers pressure medium into the wheel cylinder (51), which previously could not be fed with pressure medium owing to a fault. With the method according to the invention, universal monitoring of the entire brake system is achieved by simple means.

Abstract: 5n7 A character bit map is skeletonized using competitive locally independent processes (CLIPs) by defining for each foreground pixel an individual CLIP with a center location and radius defining the pixels included in the CLIP. In iterative cycles, each CLIP varies its center location and radius over predetermined ranges to produce a predetermined number of permutations thereof, computes a trial fitness value for each permutation, the trial fitness value being rewarded and penalized in accordance with foreground and background pixels included in the CLIP and penalized for each pixel included in both the CLIP and in another CLIP of greater fitness value. Each CLIP adopts the maximum trial fitness value as its next fitness value along with the corresponding center location and radius. Each CLIP is eliminated if its next fitness value falls below a predetermined minimum value. Whenever an iterative cycle fails to produce a change in the number or radii of the CLIPs greater than a predetermined threshold, the center locations of all surviving CLIPs are output as a skeleton character map.
