The application describes a "jellyfish" acoustic array. The array is housed in a cable suspended container with an open bottom. A series of individual transducer elements are stacked inside the container, and may be deployed in a column hanging from the container. Spacer cables join adjacent transducer elements to limit the separation of the deployed elements. The uppermost of the transducer elements is suspended from the container. Control cables secured to the bottommost of the transducer elem...

A target array in which a struck pendulous target rotates past and interacts with a shock absorber before coming to rest in a set position on a ledge. The shock absorber consists of a laterally-extending shaft that extends through a piece of pipe. The diameter of the shaft is appreciably less than the inside diameter of the pipe, so that the pipe is pendulously supported on the shaft. The shaft is parallel to but spaced from the axis about which the target rotates. The spacing is such that as th...

An improved detector array for scan receiver applications whereby each contiguous element of the array is connected to a summing port with its adjacent element.

A sensor array includes a number of discrete elements each comprising a dielectric body and two electrodes. Dielectric body has an annular skirt and the electrodes define an annular gap in which an end portion of the skirt is located. Body is displaced relative to the electrodes upon application of pressure thereto, causing the skirt to further penetrate the gap and cause a detectable change in capacitance of the electrodes, related to the magnitude of the applied pressure. The dielectric bodies...

An improved cuvette array for a centrifugal analyzer is disclosed. The array is conventionally formed from upper and lower discs of flexible thermoplastic material, in which the lower disc is formed with a plurality of compartments circumferentially spaced about a first central hub, and the upper disc is bonded to the outer periphery of the lower disc and closes an outer peripheral portion of the compartments. The array is improved by forming the upper disc with a central portion that includes a...

An array of pushbuttons is formed as a one-piece molding with interconnecting flexible strips which allow for individual movement of each pushbutton. This process results in pushbutton switch assemblies which are economical and which may be placed in subscriber telephone sets without danger of misplacement of individual pushbuttons.

A four stage pipelined processor (40) provides efficient processing of the most common operation performed in simulating neuron networks. A first stage of the processor includes a program memory (42) and a program address generator (41). A second stage comprises first and second data memories (44, 46) and respective address generators (60, 66) coupled thereto. A third stage comprises the input (X, Y) of a function unit (82), and a fourth stage comprises the output (Z) of the function unit (82). ...

The mean drift speed of charge carriers in a semiconductor element can be increased if this semiconductor element has narrow layers which are alternately n-doped and p-doped on their planes, with undoped semiconductor material between these layers. A structure of this type is however difficult to manufacture, since it requires both doping zones in layer thicknesses of 2 nm and undoped semiconductor material between these doped zones. The semiconductor element in accordance with the invention the...

A systolic array of cells for processing a data stream includes an arrangement of nearest-neighbor connected boundary cells, internal cells and a multiplier, arranged as a triangular array and a column. The boundary cells are diagonally interconnected. Each boundary cell evaluates sine and cosine rotation parameters from data received from above for lateral transfer to a neighboring internal cell, and multiplies a diagonal input by the cosine parameter for diagonal output. Each internal cell rec...

It is a question of a valve array with a number of electrically operated valves which are placed on a mounting face, common to all of them, of a rectangular prismatic connection body. Feed ducts in the interior of the valves and controlled fluid ducts are connected with feed ducts and load ducts running through the connection body. The same are connected with distribution ducts which are formed in a manifold body which is also mounted on the connection body. The valves have venting ducts which a...
