摘要： Data which is transmitted over the internet or other transmission networks is first divided up into individual information packets, transmitted and then reassembled into useful data after reception. Parity packets are included in with the information packets in the transmission of data in order to enable the regeneration of any information packets which were lost or damaged during transmission. The grouping of information packets and parity packets derived therefrom is termed a chunk. Chunk arrangements to recover from all cases of single and double lost packets are disclosed. Bursts of lost packets are recovered by interleaving the transmission of packets from different chunks. If the recovery is not successful then retransmission occurs in a manner similar to TCP.

摘要： A circular touch sensor having very linear response in a two coordinate system. This circular sensor has four substantially identical and symmetrical quadrants, with points for the introduction of potentials being located at polar and equatorial points on the sensor. The sensor has a uniform electrical sheet resistivity, and each quadrant has a resistance element to distribute the potentials to electrodes connected thereto which are positioned along the perimeter of the circular resistive surface. Individual ends of the resistance element in each quadrant are connected to their respective "tie points" through a resistor of a size to adjust for a proper resistance value between the quadrants at these points. The size (effective length along the position path) of the electrodes in each quadrant generally increases, and the spacing between electrodes generally decreases, symmetrically from the edges of each quadrant toward the center of that quadrant. In this manner, voltage gradients are produced at each of the electrodes to compensate for any cumulative voltage drop along the resistance element due to current flow into the resistive surface and due to the circular geometric configuration. In the preferred embodiment, a "floating" conductive element is placed on the path of the electrodes proximate the tie points to further enhance linearity of the sensor near these points. A typical sensor of this type is described in detail.

摘要： A fabric touch sensor for providing positional information related to a touched region/points. The improved electrographic touch sensor (10) is fabricated using at least one resistive fabric layer (12) in the form of conducting threads. This fabric is constructed using either unidirectional threads (16) or crossed threads (16, 18) formed by overlaying one set with another or weaving the two sets together. The fabric (12) is separated from a second resistive layer (14) to prevent unintentional contact, with separators (24) in the form of non-conducting threads (42), insulator dots (24), or with an air gap. In a preferred embodiment, both resistive layers are fabrics (12, 14) formed from conductive threads. Prevention of Moire-type visual patterns is achieved by orienting the threads in one fabric layer at an oblique angle to those of the second fabric layer. This sensor results in ease of fabrication, reduction of cost, reduction of parallax and eliminates substrate problems associated with those sensors employing the same. No preforming is required to adapt this sensor to a contoured object (36) when both resistive layers are fabric.

摘要： A connector compatible fiber optic replacement module for use in a local area network coaxial hub for direct communication with TTL level signals to provide a fiber optic communication link. The system uses a first amplification stage having a circuit design which provides a precisely controlled input impedance to allow unit to unit repeatability of response of the circuit in a simple and easy manner. High-frequency response of the circuit is provided by a cascode transistor pair configuration which limits the effects of virtual capacitance. Direct coupled biasing is employed throughout the receiver circuit to limit the number of components utilized. The transmitter circuit employs a standard TTL open collector driver circuit used in peripheral units to drive an infra red LED for transmission over fiber optic communication link.

摘要： An electrographic sensor for the generation of coordinate signals corresponding to contacted positions on the sensor is described. This sensor is of particular value for placing in intimate contact with the nonplanar face of a cathode ray tube or the like. The sensor has a rigid, optically transparent substrate with a nonplanar configuration matching the nonplanar face of the CRT to reduce parallax. This normally involves a radius of curvature, in one or more directions, in a range of 15-50 inches (38-127 cm). The surface of the substrate which will not contact the CRT is coated to provide a very uniform, substantially transparent, electrically resistive layer, and electrodes are connected to the resistive layer whereby orthogonal electrical potentials may be applied to the layer. Overlying and spaced from the resistive layer is a semirigid transparent cover sheet, the face toward the resistive layer being appreciably conducting. Dispersed small areas of insulation, of minimum height, prevent contact of the resistive layer and the conducting face unless the cover sheet is depressed by an object such as a finger or stylus.
