Title: Improvements in or relating to circuit arrangements for detecting malfunctioning in interrupt signal generators for microprocessor systems
IPC: G06F11/28
Filed: 1981-09-07
Abstract: A circuit arrangement detects malfunctioning in a plurality of interrupt signal generators CTC1-CTCn of a microprocessor system. The arrangement comprises a register RG which stores codes indicating the priority of an interrupt request. A comparator CM compares the code a from the register RG with a code b from a random access memory RAM and generates an alarm signal if a>/=b. The memory RAM stores the codes from the register and is addressed by an updown counter CN, which is incremented when an interrupt request begins to be processed and decremented when processing of an interrupt request finishes. An alarm signal is thus produced when an interrupt request of lower priority than or the same priority as that being processed is accepted. <IMAGE>

Title: Temperature compensation of strain gauges
Inventor: GREENWOOD JOHN CHRISTOPHER
IPC: G01L1/22
Filed: 1981-10-01
Abstract: A strain gauge comprises a silicon layer 12 with doped areas R1, R2, R3 and R4 forming piezo-resistive devices connected as a bridge whose imbalance is a measure of strain. A second similar silicon layer with similar piezo-resistive devices R5, R6, R7 and R8, is pre-strained by a wedge 21 to a fixed extent. The two bridges R1 to R4 and R5 to R8 are connected in a common circuit so that the temperature response of bridge R5 to R8 compensates for variations with temperature in the response of bridge R1 to R4. <IMAGE>

Title: Memory refreshing
Inventor: RETTER CHARLES T
IPC: G06F9/32
Filed: 1982-07-02
Abstract: A 32768 word memory is arranged in two banks each containing a plurality of 1-bit wide RAMS having paralleled address inputs A0 to A6. During normal operation the ALU of the computer provides the addresses or ALUOUT 1-15 to registers 306, 306, 310 and 312, ALUOUT 9-15 are used to provide a row address R0 to R6 on A0 to A6 in the presence of RAS (row address select). For read and write operations ALUOUT 2-8 are then used in the presence of CAS (column address select) or WE (write enable) to provide a column address C0 to C6 on A0 to A6. ALUOUT 1 selects between the banks. For a refresh cycle the ALU provides only the row address R0 to R6 and both RAS are selected to refresh both banks simultaneously by a partial read operation. When a main power supply failure is sensed and memory energisation is transferred to a back-up power supply, the registers 306 and 308 are switched to operate as counters so that row addresses R0-R6 are provided sequentially independently of the ALU. <IMAGE>

Title: Motion limiting system
Inventor: CAMPBELL DOUGLAS RICHIE
IPC: G09B9/14
Filed: 1983-05-16
Abstract: A system and method for limiting the motion of the motion platform of a vehicle simulator in which the motion platform is supported on a plurality of extensible members, the extension of the members being controlled by commands initiated by a user of the simulator. At least one absolute limit is set for at least one parameter such as position or velocity of the extension of each of the members, and the parameter is maintained within the limit. The commanded or actual magnitude of the parameter is monitored for each member relative to that members absolute limit, the member for which the monitored relative magnitude is the greatest is determined, and the limit determined for each of the other members is scaled down such that a movement of the motion platform which causes the parameter for any one member to reach its absolute limit also causes each of the other members to reach its scaled down limit at the same time. <IMAGE>
