    • A fiber-coupled receiver and associated method are provided for detecting two-dimensional and three-dimensional images in a cost-effective manner. The fiber-coupled receiver includes a plurality of optical fibers extending between respective first and second ends. At least some of the optical fibers impose different optical delays such that signals that are received in parallel by the first ends of the optical fibers are emitted at different times from the second ends of the optical fibers. For example, at least some of the optical fibers can have different lengths to thereby impose different optical delays. The fiber-coupled receiver also includes at least one detector for receiving the signals emitted at different times from the second ends of the optical fibers such that the signals that are received in parallel by the first ends of the optical fibers are received in series by the detector. By presenting the signals in series to the detector, the fiber-coupled receiver need not include a detector having separate array elements for each optical fiber. Instead, the fiber-coupled receiver of the present invention has a significantly fewer number of detectors than the number of optical fibers since each detector can receive signals in series from a number of optical fibers.
    • 提供了一种光纤耦合接收机和相关方法,用于以成本有效的方式检测二维和三维图像。 光纤耦合接收器包括在相应的第一和第二端之间延伸的多个光纤。 至少一些光纤施加不同的光学延迟,使得由光纤的第一端并联接收的信号在与光纤的第二端不同的时间发射。 例如,至少一些光纤可以具有不同的长度,从而施加不同的光学延迟。 光纤耦合接收机还包括至少一个检测器,用于接收在光纤的第二端的不同时间发射的信号,使得由光纤的第一端并行接收的信号由 探测器。 通过将信号串联提供给检测器,光纤耦合接收器不需要包括用于每个光纤的具有单独阵列元件的检测器。 相反,本发明的光纤耦合接收机具有比光纤数量少得多的检测器数量,因为每个检测器可以接收多个光纤串联的信号。

    • A communications controller for interfacing multiple analog telephone terminals to an integrated services digital network (ISDN) line connected to a telecommunications network, the ISDN line having two bearer (B) channels and a data (D) channel. The controller comprises an ISDN interface providing a physical bi-directional interface to the two B-channels and the D-channel of the ISDN line. A base logic processor, and D-channel protocols process supports a Q.931 protocol with a central office of the telecommunications network and an X.25-based protocol with a remote device, via the ISDN interface and D-channel over which command and response packets to and from the base logic processor with the central office or the remote device are transmitted. Multiple analog interfaces are adapted to support respective telephone terminals for passing bi-directional analog voice signals. Selectable coders/decoders (CODECs), connected to respective analog interfaces, encode the analog voice signals to digital pulse code modulation (PCM) or adaptive differential PCM (ADPCM) and decode PCM or ADPCM to analog, as selected by the base logic processor. A bandwidth controller connects, via the ISDN interface, the encoded voice signals to or from the selectable CODECs with communication subchannels allocated among bandwidth of the B-channels, as directed by the base logic processor, forwarding precisely timed bandwidth availability. The communications controller supports up to five telephone connections concurrently through the telecommunications network.

    • A system for interfacing a plurality of analog telephones to an integrated services digital network (ISDN) line of telecommunications network is disclosed. The system comprises a plurality of line interface units connected to respective telephones and a distribution line, and a communications controller interconnects the distribution line and the ISDN line. The communications controller transmits digital data frames on the distribution line, each frame having a frame start and a plurality of control channels and voice channels of which respective voice and control channels are associated with respective line interface units. The controller can instruct each line interface unit on the control channel of that unit, to issue ringing voltage, dial tone, busy tone or ringing tone, and it selectively couples the voice channels to the ISDN line. Each line interface unit can inform the communications controller, on the control channel of that unit, of switch-hook status of the connected telephone, a dialed directory number or dual tone multi-frequency (DTMF) digits collected. It also performs analog to digital coding and decoding of outbound and inbound voice signals, respectively, between the connected telephone and the voice channel of that unit.

    • A subsea well installation is equipped with means for performing required control functions as directed by electrical command signals transmitted over a primary cable from a remote surface location. The subsea installation includes a logic system which effects desired normal or emergency control functions according to self-contained programs or in accordance with instructions received from the surface. Multiplexing means at both locations substantially reduce cable dependency and reduce the number of electrical conductors required in the cable. Cable dependency and signal traffic are further reduced by the provision of self-contained means in the subsea logic system which verify that correct instructions have been received without need for retransmitting the received instructions to the surface. When the primary cable is damaged or communications are otherwise interrupted, a special subsea logic is initiated to control operation of the well installation and a submerged buoy is automatically released. An auxiliary cable is carried by the buoy to the water surface to permit power and communications to be re-established with the underwater installation. The buoy may also carry a storage battery or the subsea logic system, or both, so that the buoy may be released to carry these components to the surface as required for repair or periodic maintenance. Communications and power connections between the underwater installation and the cable are established through waterproofed, inductive coupling means which permits the cables to be quickly and easily connected and disconnected from the well installation without diver assistance.

    • A steering system for a work vehicle towing a towed implement is described. A steering control unit is coupled to a location signal generation arrangement on the vehicle, a steering actuator, a memory for storing desired path data of the implement and a slope sensor for detecting a lateral inclination of the work vehicle or the implement. The steering control unit calculates a lateral offset compensation value to steer the work vehicle such that the implement is moved on the desired path and a slope offset compensation value based upon a signal from the tilt sensor to compensate for slope forces pulling the implement down a lateral slope. A steering signal is sent to the steering actuator based upon the lateral offset compensation value and the slope offset compensation value.
