摘要： A memory system or a digital signal processor (DSP) includes single-bit-error detection hardware in its level two (L2) memory controller to mitigate the effects of soft errors. Error detection hardware detects erroneous data that is fetched by the central processing unit and signals the central processing unit. The parity is generated and checked only for whole memory line accesses. This technique is especially useful for cache memory. The central processing unit can query the memory controller as to the specific location that generated the error and decide the next course of action based on the type of data affected.

摘要： An electrical connector including a first and second assembly that are matable with one another by a sliding push fit to establish electrical interconnection between the two assemblies is disclosed. The first assembly includes a contact pin with a collar extending concentrically around the pin to define a recess therebetween, with the collar supporting on its inner surface a first resilient contact element. The second assembly includes a sleeve open at one end thereof such that the sleeve can be received in the recess of the first assembly, with the sleeve supporting on its inner surface a second resilient contact element. The two assemblies may be arranged such that, when the second assembly is inserted into the first assembly, the first resilient contact element makes sliding electrical contact with an external surface of the sleeve of the second assembly, and the second resilient contact element makes sliding electrical contact with the external surface of the pin of the first assembly.

摘要： The parity of this invention includes two arrays of parities surrounding the memory. One array is generated in parallel. The other array is generated in serial. The two dimensional parity is used to protect, locate and correct errors automatically. The second parity is provided for only a subset of the address range of the memory. The memory controller does not compare the second parities unless there is a soft error in the first parity. The second parities are calculated upon command and not upon each memory write as the first parity.

摘要： An electrical connector for high current applications has a mating plug and socket assembly. The socket assembly has two sockets arranged coaxially of one another and electrically interconnected. The central socket receives and contacts a pin on the plug assembly; the other socket contacts the external surface of a tubular sleeve surrounding and integrally electrically connected with the pin. The socket assembly also has a third socket electrically insulated from and arranged coaxially outwardly of the other two sockets. The third socket makes electrical contact with the outer surface of a tubular contact extending coaxially of the pin and electrically insulated from it. The sockets each have a hyperboloid configuration of multiple resilient wires to make contact with the pin, sleeve and outer contact.

Each optical connector is resiliently mounted in an alignment sleeve by means of a spring clip encircling the connector and contacting the sleeve. The alignment sleeves are themselves resiliently mounted in passages through the housings by spring clips encircling the sleeves and contacting passages within which the sleeves are mounted.

摘要： In the modulation and demodulation of a plurality of frequency separated channels on a radio frequency carrier by digitally coded speech or data, the speech or data is modulated on a digitally generated sub-carrier by quadrature phase shift keying and after conversion to analogue form the modulated sub-carrier is mixed with an RF carrier of fixed frequency to produce the signal for transmission. Reception and demodulation of the transmitted signal are effected by the reverse processes. Frequency multiplication is effected after the digital to analogue conversion by producing analogue samples of very short duration and applying them to a suitable filter. Frequency division during the analogue to digital conversion is effected by sub-sampling.
