Patent EP-0477690-A1 (EP)
Inventor: KERNER HORST
IPC: H03H17/02
Filed: 1991-09-12
Abstract: This method involves multiple formation of differences, these differences being coded in such a manner that those with a higher probability of occurrence are allocated shorter code words than those having a lower probability of occurrence. The number of differences formed is selected in such a manner that the coding of the differences results in a minimum of the mean code word length. In the digital processing of the signal values, this results in a reduction in the storage space required or in the transmission time. The invention is used in recording measuring instruments, particularly for network supervision. <IMAGE>

Abstract: The wheel chair of the invention is remarkable in the respect, that it incorporates three or more link units between the lateral frames (R), each link unit comprising two linking arms (1, 2) connected in a common junction point between the two lateral frames. The junction point comprises two parallel lateral plates (3), between which the linking arms (1,2) are swingably suspended in mutually displaced swinging planes. In their unfolded position the two linking arms (1,2) intersect, the swing journal of the first arm (1) forming a stop face for the second arm (2) and vice versa. The linking arms (1,2) are provided with toothed wheel segments (11) in mesh. This mesh or engagement of the teeth secures a synchronization of the movements of the two arms (1,2) when the chair is folded or unfolded. By simultaneously establishig not-bendable connections between the junction points, effective guidance in parallel of the two lateral frames (R) is obtained, when the chair is folded. This guidance in parallel is a prerequisite of the correct movement of the link mechanism, i.e. the link mechanism should not be turning over or canting, when handling the chair, which would make the link bearings jam.

Abstract: A clock-driven pulse source is used to apply repetitive short pulses to the squelch control connection point of the squelch circuitry of a radio receiver to deactivate momentarily the squelch circuitry at regular intervals. This provides periodic noise bursts of "de-squelch" pulses on an otherwise silent radio in order to inform the radio operator that the radio is live and that the volume is adequate. A light may also be connected to the system to provide a second, visual, indicator of the operational status of the radio. 
     This radio receiver operational checking system may also be utilized where there are two or more radios in use by providing an additional clock-driven pulse source for each radio in use. The system may be arranged so that the status of individual radios may be quickly ascertained by sound and/or by light indicators.

Abstract: An integrated circuit memory is disclosed which includes redundant columns associated with a sub-array (12), and in which multiple input/output terminals are placed in communication with multiple columns in the sub-array in read and write cycles. The number of redundant columns per sub-array is less than the number of input(38)/output(20) terminals. A multiplexer connects the selected redundant column to a selected sense amplifier and write circuit for the input/output with which the replaced column was associated. The multiplexer includes pass gates connected to the bit lines of the redundant column, and fuses connected between each of the pass gates and each of the sense/write circuits selectable for the redundant (25) column. Those of the fuses which are not associated with the selected input/output are opened, and the fuses associated with the selected input/output are left intact. Precharge transistors are connected to the fuse sides of the pass gates, for precharging each of the floating nodes after the pass gates are turned off. This precharging negates the effect of any charge which may be trapped on the fuse side of the pass gates for those lines where the fuses are opened, so that the access time for the next cycle will not be degraded.

Abstract: The pressure vessel comprises a bottom part (1) and a lid-like top part (2). In the region of the closure of the bottom part (1) and the top part (2), each of them has on its outside a profile (7 and 8 respectively) which extends in the circumferential direction of the pressure vessel and in which at least three coupling parts (9) in the shape of annular segments, distributed over the circumference of the pressure vessel and profiled to correspond to the profiles (7 and 8) engage in the closure position. The coupling parts (9) for their part are surrounded by an axially displaceable ring (11) which interacts with them. The ring is designed in such a way that, when it is moved into the closure position, it brings the profiling of the coupling parts (9) into engagement with the profiles (7 and 8) and, when moved into a second position, displaced axially relative to its closure position, it brings the profiling of the coupling parts (9), on the one hand, and the profiles (7 and 8), on the other hand, out of engagement.

Title: Fault tolerant computer system.
Inventor: MAJOR DREW
IPC: G06F15/16
Filed: 1991-08-09
Abstract: A method and apparatus for providing a fault-tolerant backup system such that if there is a failure of a primary processing system, a replicated system can take over without interruption. The invention provides a software solution for providing a backup system. Two servers are provided, a primary and secondary server. The two servers are connected via a communications channel. The servers have associated with them an operating system. The present invention divides this operating system into two "engines." An I/O engine is responsible for handling and receiving all data and asynchronous events on the system. The I/O engine controls and interfaces with physical devices and device drivers. The operating system (OS) engine is used to operate on data received from the I/O engine. All events or data which can change the state of the operating system are channeled through the I/O engine and converted to a message format. The I/O engine on the two servers coordinate with each other and provide the same sequence of messages to the OS engines. The messages are provided to a message queue accessed by the OS engine. Therefore, regardless of the timing of the events, (i.e., asynchronous events), the OS engine receives all events sequentially through a continuous sequential stream of input data. As a result, the OS engine is a finite state automata with a one-dimensional input "view" of the rest of the system and the state of the OS engines on both primary and secondary servers will converge.
