Abstract: A direct optical connector (DOC) comprised of first (201) and second members, each including a plurality of light emitting (202, 204) and light detecting (205, 203) locations, operative in combination with energy transfer media (210) to form direct optical connections between the light emitting locations (202, 204) and the light detecting (203, 205) locations, wherein said first (201) and second members are adapted for reclosable connection to each other whereupon the light emitting locations (202) on one member are aligned with the light detecting locations (205) on the other member. The first (201) and second members of the preferred DOC are modular. Alternative forms of energy transfer media (210) are used in various embodiments of the invention including lenslet arrays, imaging fiber plates (IFPs), and energy transfer fiber plates (ETFPs). These media have differing alignment criteria, differing degrees of immunity from crosstalk, differing degrees of transfer efficiency, different manufacturing costs, etc., thereby permitting the fabrication and/or use of a connector most suited to meet the requirements of a particular application. A modular half of a DOC can be used in conjunction with a remote optical connector (ROC) to channel light over relatively long distances. The invention also encompasses processes for fabricating ROCs.

Abstract: A method and apparatus for removing wires bonded between chip contact pads (60) and substrate contact pads (10) using an alternating fluid flow is described. The fluid flow is preferably air. A nozzle having a plurality of air jets within a chip accommodating cavity is disposed over the chip to enclose the chip contact pads, the substrate contact pads and the wires bonded therebetween. Air is forced through the plurality of jets to cause an alternating clockwise and counter clockwise air flow which bends the plurality of wires back and forth until they fatigue at the contact points to the chip contact pads in a substrate contact pads which results in the wires being substantially simultaneously severed therefrom. The nozzle has an aperture out through which the air escapes carrying the severed wires therewith for collection in a filter.

Abstract: A hitch feeder for a TAB tape is described which comprises: a stationary jaw assembly (12) having opposing jaws for gripping edges of the tape when closed, and not gripping the edges when open; a movable gripping assembly (10) which includes a lower movable gripper positioned below the tape (22) and an upper movable gripper positioned above the tape. The lower and upper movable grippers may be moved both towards and away from the tape, each said movable gripper gripping the tape when moved towards it and releasing the tape when moved away from it. Both grippers are physically clear of any features on the tape when moved away from it. A tape feeder is provided for reciprocally moving the movable gripper assembly along the tape length, both towards and away from the stationary jaw assembly. A feed control is operative when the movable gripping assembly moves towards the stationary jaw assembly, to move the gripper jaws to grip the tape and to open the opposing jaws, and is further operative when the movable gripper assembly moves away from the stationary jaw assembly, to move the gripper jaws away from the tape and to close the opposing jaws.

Abstract: Gemäß einer Technik wird eine elektronische Einheit so konfiguriert, dass sie charakteristischen Eigenschaften einer biologischen Synapse entspricht. Die elektronische Einheit weist mehrere bipolare Widerstände auf, die parallel angeordnet sind, so dass sie eine elektronische Synapse bilden, eine Axonverbindung, die mit einem Ende der elektronischen Synapse und mit einem ersten elektronischen Neuron verbunden ist, und eine dendritische Verbindung, die mit einem anderen Ende der elektronischen Synapse und mit einem zweiten elektronischen Neuron verbunden ist. Ein Zunehmen und Abnehmen der synaptischen Leitfähigkeit in der elektronischen Synapse beruht auf einer Wahrscheinlichkeit eines Umschaltens der Vielzahl von bipolaren Widerständen zwischen einem niederohmigen Zustand und einem hochohmigen Zustand.
