Abstract: In a machine for loading tape into cassettes, the cassettes to be processed are oriented horizontally and disposed one upon the other to form a stack vertically engaged in a magazine. A collapsible support located at the base of the magazine engages the lowermost cassette in the stack in order to orient it vertically and let it fall into fitting guide pieces associated with a loading station located in the loading machine. A retention element operable by an actuator maintains the positioning of the cassette on the collapsible support while the latter is moving to the dropped position.

Abstract: An apparatus as provided for use in carrying out electrochemiluminescence test measurements. The apparatus includes a fluid container having an inlet for introducing an electrochemiluminescence sample fluid and a fluid outlet. The fluid container is composed of a durable, transparent, chemically inert, and electrically nonconductive material. A working electrode is disposed to one side of a fluid flow path of the container which has a light transmissive wall opposite the working electrode. A counter electrode is secured to the light transmissive wall. A first portion of the counter electrode is disposed upstream of the working electrode, while a second portion of the counter electrode is disposed downstream of the working electrode.

Abstract: A plurality of tape cassettes fed in succession from a conveyor are oriented vertically on an end stretch of the conveyor itself terminating at a position in side by side relation with a tiltable collection element. The cassettes are pushed laterally from the end stretch of the feed conveyor for being loaded onto the collection element until they form thereon a row comprised of a given number of cassettes. The collection element is then tilted to let the cassette row fall onto a tray previously positioned under the collection element.

Abstract: A current-mode Hamming neural network is provided with N binary inputs, and has a template matching calculation subnet and a winner-take-all subnet. The template matching calculation subnet includes M first neurons in which M exemplar templates are stored respectively. Each first neuron is consisted of current mirrors connected to and controlled by the N binary inputs respectively, to generate a template matching current signal which is substantially proportional to the number of matched bits between the N binary inputs and the corresponding stored exemplar template. The winner-take-all subnet includes M second neurons, each including M transistors with their gate electrodes connected together to form a template competition node, their source electrodes connected to ground, and their drain electrodes connected to the template competition nodes respectively.

Abstract: Recent advances in surface techniques have lead to the development of extremely small (sub-micron) scale features. These techniques allow the formation of polymer micro-lenses as well as variable focus liquid lenses. The present invention primarily concerns the use of small scale lenses for the fabrication of novel displays which exhibit three-dimensional (3D) effects. Both still images and video images (or other motion images) can be generated.

Abstract: A flexlead circuit assembly is provided for use in a rotary disk storage system and is designed so that the inherent bias force exerted by the flexible circuit on the actuator arm of the disk storage system is negated. The flexlead circuit herein is split into two sets of flexlead conductors: one to supply power and ground to the actuator VCM and other to transmit signals to and from the read/write heads. The end of each of these flexlead conductors opposite to the end mounted to the actuator arm is integrally formed with and provides signal communication with a printed circuit mounted within the housing. The printed circuit is formed on a substrate which is snap-fit to the lower plate of the disk drive housing to thereby not only support the printed circuit within the housing, but also to provide mechanical support for the flexlead circuit.
