Abstract: A networking method is disclosed. At least one silent slot is included in either a collision detection prefix disposed before a preamble of one or more frames of data to be transmitted across a media or in the one or more frames of data to be transmitted across the media. Transmission collision is detected during the at least one silent slot included. In one embodiment, the method is embodied in a network interface controller having a media access control block to control access to a media, and a physical signal block to physically signal data to be transmitted. The media access controller includes the at least one silent slot in either the collision detection prefix or in the data, and the physical signaling block performs the transmission collision detection during the included at least one silent slot.

Abstract: A fax machine works as a fax machine, and is capable of sending and receiving image data by email. In addition to a fax type scanner and fax type printer, the device includes an alphanumeric keyboard, a processor and a memory. The device is configured as a customer for an internet service provider, with its own email address, i.e., a user name and password. The device includes an internet type modem that is set up for calling either another fax machine or a customer number of the provider. The user enters in the keyboard either the telephone number of the other fax machine, or the email address of the addressee. The processor determines which one is entered by examining the entry for the “169” character of an email address. If it is a regular fax transmission, the other fax machine is dialed, and the document is scanned and transmitted.

Abstract: Briefly, in accordance with one embodiment of the invention, a power brick for use with a network adapter includes: a power supply and at least one signal transformer. The power supply and the signal transformer are physically remote from the network adapter and capable of being electronically coupled to the network adapter via a cable.

Abstract: A visibility enhancement system for a CNC machine center that incorporates a windshield wiper assembly. The CNC machine center has a door with a window for viewing machining operations therein. The windshield wiper arm and its wiper blade are mounted on the inner surface of the window in the door. The windshield wiper assembly has structure on the outer surface of the door for reciprocally rotating the windshield wiper arm back and forth through a predetermined angle. The windshield wiper assembly has spring means for constantly pressing the wiper blade against the inner surface of the window. The windshield wiper arm has an adjustable length arm that allows different lengths of wiper blades to be used.

Abstract: Linear list based direct memory access (DMA) control structure for controlling a DMA processor through a linear list of DMA descriptors in memory. A descriptor entry is deposited at the end of the linear list. Each descriptor entry has an address associated with their location in the linear list. A pointer to the linear list points to a single location in the linear Fist. A next descriptor entry is accessed by decrementing the address corresponding to the single location. The descriptor entries are read from the linear list of DMA descriptors DMA transfers are performed.

Abstract: A seat frame for mounting on a chair frame for supporting a seat pad and seat back. The frame is formed by a pair of spaced apart side rails, each rail having a plurality of spaced apart parallel transverse mounting beams extending therefrom towards the opposite rail. A central beam is telescopingly and releasably engaged between each corresponding mounting beam on the rails. Chair frame mounting fittings and seat back mounting fittings are releasably secured to the side rails.

Abstract: A pair of variably adjustable lower body supports such as footnests or legrests are adapted to be mounted on a wheel chair. Each support is mounted on one of two tubular receptacles on the front of the frame of the wheel chair. The support includes four elongated structural members and a planar footplate. Each of the structural members are sequentially linked together by a releasable rotary connection. The releasable rotary is formed by a splined shaft attached to one structural member and a splined sleeve attached to the next structural member. A releasable fastening device is used to hold the splined sleeve onto the splined shaft so that the sleeve can be selectively rotated relative to the shaft angular of the support and footplate relative to the wheel chair frame.

Abstract: A detent for releasably securing an inner telescoping tube within an outer telescoping tube. The said tubes having alignable openings in the walls thereof for receiving the detent. The detent is formed by a detent pin which extends through the tube wall openings and releasably latches the tubes together. A leaf spring secured at the inserted end of said inserted tube extends within the outer tube into supporting and biasing engagement with the detent pin. The spring biases said pin into the latching position. For releasing the detent, a bell crank is pivotally mounted within the inserted tube. One end of the bell crank is engaged with the locking pin and biasing spring and the other end is secured to an actuating knob which extends through the wall of the inserted tube.
