Title: Evaluation of median
Inventor: CULVERHOUSE PHILIP FREDERICK
IPC: H03H17/02
Filed: 1989-05-31
Abstract: The N members of a set of data (7) are compared (5) with a median estimate (9) and a vote generated to indicate whether the set member (7) is not less than the median estimate (TRUE) or otherwise (FALSE). Votes are counted using a counter (11) and the count passed to a majority circuit (13) to determine whether the number of votes that are set TRUE represents a majority of the total number of votes passed and control updating of the median estimate. Iterations are performed until the median is evaluated. Comparisons may be performed on one bit of each word at a time. <IMAGE>

Filed: 1989-11-16
Abstract: Actuator of the artificial muscle type has first and second tensile substrates (2, 4), each made of a relatively inelastic material such as carbon ribbon, arranged to extend spaced from and substantially parallel to each other. A compressive structure (6) is supported between the two substrates (2, 4) to define an individual cell of the actuator. This compressive structure (6) includes two substantially identical compressive blocks (8), arranged between, and carried by, the two substrates (2, 4) to define a passageway (10), which communicates at its ends with an articulation cavity (16). A plurality of the cells are embedded in an elastically deformable matrix (20) such that when pressure is applied thereto in sequence, digitally incremented shape changes can be made in the actuator. The actuator forms a composite structure. A number of such cells can be confined to form a flexible arm or tentacle e.g. for prosthesis. The tentacle has the cells connected to an articulated spine structure. <IMAGE>
