Title: Invalidation of index items for a temporary data store
Inventor: HUGOSSON OLA
IPC: G06F12/12
Filed: 2013-12-16
Abstract: A temporary data store 12, such as a cache memory, stores data items retrieved from a memory 13, such as a frame buffer. Locations for new data items are allocated in a circular sequence. Each data item has a corresponding index entry. This is stored in an index data store 11, such as a tag memory. The index entry indicates whether the corresponding data item is valid. The data items are invalidated when they have been stored for a predetermined time or when a predetermined number of new data items have been added to the store. The data items may be checked when a new item is added. They may be checked in a circular sequence. A sequence number, which is incremented for each new entry in the data store, may be stored in the index entry. This may be used to determine whether the entry should be invalidated.

IPC: G08B13/187
Filed: 2014-05-06
Abstract: A scanned bistatic intruder detection radar system comprising at least one pair of wirelessly communicable detection nodes operable to define an electromagnetic field detection zone therebetween. Transmitter units 12 and receiver units 14 define electromagnetic field 16 such that an analysing means communicable with the system may monitor the field for disturbances and thus infer the presence of a target within the detection zone. Each node may be electronically switched between a plurality of scan angle configurations such that a targets baseline crossing point or direction of movement may be determined more precisely by utilising configurations that focus a locus of points running parallel or perpendicular to the link. The system seeks to reduce the frequency of false alarms and to allow for additional target information to be gathered. The system preferably comprises a phased antenna array for transmission or reception at each node of a protection link.
