Abstract: A remapping technique for handling medium defects in a disc drive system is disclosed. Each surface on each disc is divided into a number of tracks with the corresponding tracks on all discs defining a cylinder Each surface is further divided into a plurality of sectors. Each sector in each cylinder not having a defect is assigned a logical address in a predetermined order such that, as the discs rotate and as the head address increments within a cylinder, each succeeding defect-free sector within that cylinder has a logical address which is related by a predetermined algorithm to the logical address of the preceding defect-free sector. Defective sectors are labelled with an appropriate unique pattern in their headers so that they can be identified and distinguished from logical address numbers. A predetermined number of sectors at the end of each cylinder are allocated as spares, the number of spares being at least as large as the number of potentially defective sectors in a cylinder and the number of spares to which logical addresses are assigned being equal to the number of non-spare sectors which are defective. In using the technique, each defect-free sector in a cylinder is located and assigned its logical address. In transferring information, the header address of a sector in a cylinder held in a data buffer (29) is compared (33) with the logical address expected at that logical in a register (31). tfthe addresses match the data at that sector is transferred by sequencing logic (35). If the addresses do not match the header address at the next physical sector is compared with the expected address. The procedure is repeated until the address at a physical sector match with the logical expected address. However, if the sequence of mis- matches exceeds a predetermined number, counted in a counter (45), the sequencing operation is terminated and an error signal generated by a detector (47). The technique eliminates moving the heads radially inward or radially outward to spare tracks allocated for data belonging in defective sectors as in most prior art systems.

Abstract: A method for producing a wired circuit board is disclosed in which a wire mat is first formed on a fixture (10) and then mated with a circuit board (176) having a specified conductive pad layout on the board surface. A continuous wire is routed on a fixture (10) along a predetermined path over a thermoplastic adhesive layer (62) and the wire is adhered to the layer to fixably position the wire in the routed configuration. The continuous wire is severed at selected locations to form a plurality of wire nets. A wire mat thus formed is mated with a circuit board (176) having conductive pads disposed on the board surface such that selected points of selected wires confront selected conductive pads on the circuit board. After removal from the fixture (10), compressive pressure is applied to the wire mat and circuit board to conformally adhere the wire mat to the circuit board. The circuit board and wire mat adhered thereto are next heated at elevated temperature to cure the adhesive layer. Selected points of wires confronting conductive pads on the circuit board are then soldered to the respective pads to complete interconnection of predetermined conductive pads on the circuit board thereby yielding a wired circuit board adapted to receive integrated circuit and other electrical components. A wire mat produced in the disclosed manner may be applied to one or both circuit board surfaces.

Abstract: remotely controllable relay comprises a rocker pivoted at an intermediate point for rocking at one end in normal or reverse direction in response to forward or backward motion of a movable member of an electromagnet means, and a movable contactor linked to the rocker for contacting with or separating from a fixed contactor in response to the rocking of the rocker. A larger momentum at the other end remote from the pivoted point of the rocker achieved with a smaller momentum of the movable member is utilized to sufficiently separate the movable contactor from the fixed contactor upon contact opening, the smaller momentum movable member allowing the electromagnet means to be minimized in size for a miniaturization of the relay and consumed power saving.

Abstract: A blood pump comprises an atrium chamber defined by flexible walls and having an inlet and an outlet, a ventricle chamber defined by flexible walls and having an inlet and an outlet, a passage communicating the outlet of the atrium chamber with the inlet of the ventricle chamber, a first one-way valve in the passage adapted to permit blood flow only from the atrium chamber to the ventricle chamber, and a second one-way valve in the outlet from the ventricle chamber adapted to permit blood to flow through the outlet only out of the ventricle chamber. The chambers are movably supported in a casing having first and second openings, the atrium chamber inlet being fastened to the first opening and the ventricle chamber outlet to the second opening. A drive device cyclically moves the walls of the ventricle chamber to decrease its volume and expel blood from it while simultaneously moving the walls of the atrium chamber such that its volume may increase upon inflow of blood into the inlet to it. The drive device includes a drive ring surrounding and joined to the passage and having a surface engageable with the walls. of the ventricle chamber over a selected area such that the pressure of blood entering the chambers between driven strokes of the drive device controls the output of the blood pump by establishing the magnitude of the return stroke of the drive ring as a function of a pressure force acting over the area of engagement between the drive ring and the walls of the ventricle chamber.

Abstract: A process for repairing damaged, that is scratched, surfaces of optically transparent plastic substrates, such as polycarbonate windows or windshields of aircraft, comprises sanding the defects in the damaged surface of the substrate and applying a film of an optical grade transparent plastic material such as an acrylic plastic to the sanded surface of the substrate, by means of a clear liquid adhesive such as a silicone adhesive. Excess liquid adhesive is removed together with any bubbles and the adhesive is cured to bond the plastic film to the transparent substrate. The adhesive is chosen so that the cured adhesive has a refractive index which matches the refractive index of the substrate, thereby rendering the scratches substantially invisible, and providing clear visibility through the resulting substrate and plastic film thereon. As an additional feature of the invention, the protective plastic film can be applied to new, undamaged surfaces of transparent plastic substrates as an easily replaceable outer protective ply.

Abstract: A telecommunication and development system for the switching of voice and data under computer control in a customer programmable environment that allows real-time modification of communication services. The computer program controlling the system is written in a nonprocedural language that allows for the direct control of the telecommunication system on the basis of state definition, event definition, and action definition. Program scripts define a particular feature, and each script consists of a plurality of triples that automatically respond to the system state and signal information to execute the necessary actions to provide part of a feature to the telecommunication system. During provision of telecommunication services, a customer can add new features that not only add new operations to the system, but modify existing operations without interfering with the present operation of the system. This is possible since the nonprocedural language allows for the direct control of interaction between features and provides for the automatic execution of required operations during state transitions. In addition, the nonprocedural language allows a feature or script to control its own deactivation or activation. Also, the software development environment is based on a standard operating system allowing for ease of development. The above features allow a customer to program his or her own individual communication unit to provide desired features without affecting the operation of the telecommunication system or the features provided to other customers.
