  • Patent number: 5146515
    Abstract: A lens combination set in front of an optical fiber terminal head of an optical fiber fine displacement detecting system to focus a real image of the optical fiber terminal head so as to extend the mounting range of the head relative to the object in detection and avoid any possible damage due to collision of the object with the head. The lens combination focuses the light rays from the optical fiber terminal head to form a real image outside the lens combination. The reflected light rays from the object mounted around the real image are focused by the lens combination and sent back to the detecting system through the optical fiber terminal head. Therefore, sufficient safety range is obtained between the lens combination and the object in detection without affecting the normal operation of the detecting system.

  • Patent number: 5107444
    Abstract: A method and apparatus for flattening a three-dimensional surface into a two-dimensional pattern piece extracts a three-dimensional mesh from the surface to define surface elements and maps these elements in groups to a flat plane where they are reassembled. The position of data points in the flat plane are recursively adjusted in order to cancel error and to provide an optimum solution. Tools are provided to the user to determine the correctness of the flattening process and to insert darts into, and make other modifications to, the resulting flat pattern in order to further optimize the result.

  • Patent number: 5093824
    Abstract: A method for reconfiguring a telecommunications network comprising a plurality of reconfigurable cross-connect nodes interconnected by links when a failure event occurs is disclosed. The method comprises storing at each node a precomputed configuration table corresponding to each of a plurality of possible network topologies which can result from a plurality of possible failure events. After a specific failure event occurs, the network is flooded with messages so that each of the nodes is informed as to the specific existing topology of the network resulting from the specific failure event. The nodes are then reconfigurated in accordance with the precomputed configuration tables which correspond to the specific existing network topology.

  • Patent number: 4893306
    Abstract: A data transmission technique referred to herein as Dynamic Time Division Multiplexing (DTDM) is disclosed along with a set of multiplexers and demultiplexers required to apply DTDM in an actual telecommunications network. The DTDM technique uses a transmission format which is compatible with the existing digital circuit transmission format and the packet transmission format so that DTDM is able to handle the transmission of circuit and packet traffic. Thus, DTDM provides a flexible migration strategy between present circuit networks and future broadband packet networks.

  • Patent number: 4871739
    Abstract: There are disclosed certain 2-substituted-4-substituted 6H-7,8-dihydrothiapyrano[3,2-d]pyrimidines which have oral hypoglycemic activity and with such ability to lower blood sugar are useful in the treatment of type II diabetes and/or obesity with associated insulin resistance. Processes for the preparation of such compounds and compositions containing such compounds as the active ingredient thereof are also disclosed. The compounds are also .beta.-adrenergic blocking agonists or .alpha.-adrenergic blocking agents and act as ocular antihypertensives and are useful for the treatment of glaucoma and other eye disorders.

  • Patent number: 4866308
    Abstract: A high speed, high performance CMOS to GPI interface circuit is disclosed. The interface circuit contains an input stage, clamping circuitry, an output stage and feedback circuitry. The clamping circuitry clamps the voltage level presented to the output stage at a level below the power supply voltage when the input from the CMOS circuit is at a high logic level. As the voltage level of the signal presented to the CPI circuitry rises, feedback circuitry feeds this signal back to the clamping circuitry, which in turn decreases the voltage level presented to the output stage. This assures the signal presented to the GPI circuit falls within the specified voltage level from 1.51 and 2.2 volts. The feedback circuitry contains a single pole filter that filters out high frequency reflections presented to the feedback circuitry, and a slew rate limiter that slows the rise and fall of the voltage level presented to the output stage thereby reducing noise on the power supply and ground lines.

  • Patent number: 4850799
    Abstract: A vibration damper for a suspended ceiling fan comprising a motor mounting and a frame support plate, totally enclosed in a vibration absorbing rubber compound. The motor mounting and frame support plates are separated by an annular space that forms an outward facing annular channel. Trapezoidal shaped reinforcement ribs located in the outward facing annular channel restrict swaying of the fan blades when the motor is energized. The damper may comprise two arcuate shaped members which allows easy installation on existing ceiling fans and easy disassembly when the fan motor needs maintenance or repairs.

  • Patent number: 4796821
    Abstract: A reciprocating cutting apparatus for cutting living plant material. The cutting apparatus includes a frame. A reciprocating cutting assembly is mounted at one end of the frame for cutting the materials. The frame includes structure for synchronizing the feeding of the materials with the cutting assembly. The living plant material is fed into the cutting assembly in the upward stroke and held still on the downward or cutting stroke. The cutting assembly can be adjusted for cutting the desired strip width of living plant material. The cutting apparatus further includes structure mounted on the frame which applies pressure to the living plant material just prior to the living plant material being cut.

  • Patent number: 4794565
    Abstract: An electrically programmable and eraseable memory element using source-side hot-electron injection. A semi-conductor substrate of a first conductivity type is provided with a source region and a drain region of opposite conductivity type and a channel region of the first conductivity type extending between the source and drain regions. A control gate overlies the channel region, and a floating gate insulated from the control gate, the source and drain regions and the channel region is located either directly underneath the control gate over the channel region, partially underneath the control gate over the channel region or spaced to the source side of the control gate. A weak gate control region is provided in the device near the source so that a relatively high channel electric field for promoting hot-electron injection is created under the weak gate control region when the device is biased for programming.

  • Patent number: 4782478
    Abstract: A time-division circuit switch which serves as a cross connect for time multiplexed signals including frames subdivided into slots serves to cross-connect input and output lines on a slot-by-slot basis. The circuit utilizes a self-routing packet switching network. An input interface attached to each input line converts incoming slots into fixed length packets which can be routed through the self-routing switching network in a synchronous manner. An output interface coupled to each output line reconverts the packets into slot/frame format. To prevent blocking, the self-routing packet switching network runs at a faster rate than the input and output lines of the switch.
