Abstract: A mirrored arc geometrical arrangement of two conductors configured to perform similar functions as a traditional twisted pair of wires is presented. The mirrored arc conductor pair occupies the same physical space required by prior art twisted pair cable designs. Each conductor pair includes two inward-facing arc shaped conductors placed within a dielectric material. Each arc shaped conductor may be constructed from thin foil strips of a conducting metal or from a group of separate bare metal conductors which are placed side by side in intimate contact so as to effectively create the same mirrored arc geometry. The conductor pairs may subsequently be bundled to create a data network cable bundle.

Abstract: A method and apparatus are presented for dynamically testing video equipment. One or more test patterns utilize different regions of video signal characteristics. Adjustment is made to the video characteristics of a region until a perceived parameter of the region matches a second region. A performance parameter of said video equipment is determined from said adjustment.

Abstract: A socket wrench is provided which performs the functions heretofore carried out by two separate wrenches. To this end, the present invention provides a wrench where each end thereof selectively acts (a) as a receiving end for a nut or other fastener to be rotated by the wrench and of a different size than that to be received by the other end of the wrench and, (b) as the receiving end of a driver member which is to rotate the wrench to turn the nut or other fastener surrounded by the other end of the wrench. Preferably, the same driver member is insertable into either end of the wrench.

Abstract: A method and apparatus are presented for dynamically testing video equipment. A test pattern utilizes a presentation of alternating pixels and lines, along with features of the electronic video/graphics generator in which it is present to effect a close approximation to the demonstrable contrast transfer function percentage of the system or display under test. The test pattern, while depending on features of the electronic video/graphics generator for convenience of operation, may also be modified to be used as a static pattern capable of very similar utility.

Abstract: An unshielded twisted pair (UTP) cable minimizes skew delay of analog signals by enforcing a common electrical length among twisted pairs that carry those analog signals. By applying a different lay length and lay direction to the twisted pair that carries the digital signal, cross-talk from the digital signal onto the analog signals is minimized. The twisted pairs for carrying the analog signals may be bundled together, with the twisted pair for carrying the digital signal placed alongside the bundled pairs during the final extraction process, during which the outer insulator is formed around all of the pairs. The bundled pairs may be used for the transmission of analog video signals (e.g., R, G and B), with the remaining pair used for transmission of digital control or digital audio signals.

Abstract: An unshielded twisted pair (UTP) cable minimizes skew delay of analog signals by enforcing a common electrical length among twisted pairs that carry those analog signals. By applying a different lay length and lay direction to the twisted pair that carries the digital signal, cross-talk from the digital signal onto the analog signals is minimized. A nonconductive filler provides a central core about which the twisted pairs are wound during the bundling process. The presence of the nonconductive core ensures that a minimum distance (i.e., the diameter of the core) is maintained between non-adjacent pairs for the length of the cable.

Abstract: A cable with minimum skew for analog video and minimum crosstalk for data transmission is presented. A UTP cable of the present invention has conductors with nearly identical electrical lengths while providing minimum crosstalk between the conductors in the cable bundle. The electrical lengths of the conductors are sufficiently equal to allow use for analog video networks without undue equalization. In addition, the construction methodology results in a cable with minimum crosstalk thereby providing a cable similar in characteristics with prior art UTP cables used for data networks.

Abstract: A method and apparatus for compensating for video insertion loss due to transmission over long coaxial cable lines is presented. An Electro-Magnetic Interference suppression type filter having a ferrite core is used to simulate and thereby compensate for the effect of the cable insertion loss on video transmitted over long coaxial cables. The Electro-Magnetic Interference suppression filter has a frequency response similar to the insertion loss characteristics of a coaxial cable, especially at the low to mid frequency range, where it has been traditionally difficult both in cost and in complexity to compensate because of the frequency response characteristics of the coaxial cable. High frequency compensation is also added using a voltage variable capacitance diode device to extend the total compensated video bandwidth to beyond 200 megahertz.
