Abstract: Wheeled apparatus is usable both as a wheeled walker and as a wheelchair. The wheeled apparatus includes a foldable frame, first and second transversely spaced-apart wheels that are attached to the frame with a negative camber angle, a third wheel that is longitudinally spaced from the first and second wheels and that Is attached to the frame, and a seat cushion that is attached to the frame. When used as a wheeled walker, bi-directional seating means provides rearward facing seating for resting, and when used as a wheelchair, the bi-directional seating means provides forward facing seating. Centers of handgrips are disposed longitudinally intermediate of the first and second wheels and the third wheel to minimize danger of the wheeled apparatus tipping backwardly when used as a wheeled walker. A negative camber angle of the first and second wheels minimizes danger of the wheeled apparatus tipping sideways, and an asymmetrical folding mechanism reduces or removes the negative camber angle when the foldable frame is folded, thereby minimizing the required size of a shipping container.

Abstract: The invention concerns technics of recognition of various images. In the method a presentation of reference objects is transformed into corresponding sampled reference signals without repeating quantization levels, for a set of all these signals there is formed a dynamic system of the kind of iterable mapping of d-dimensional cube into itself with limit cycles by the number of the reference signals, presentations of an object under identification are transformed into samples of information signal, these samples are applied to the input of the formed dynamic system as initial conditions and by the results of its functioning a decision is made on recognition of the object under identification. Distinctive features of the method are the conditions of looking through the samples of information signal at the input of the dynamic system and the conditions of determining correspondence of the information signal to one of the reference signals by the phase trajectory of the dynamic system in the process of its functioning getting to one of the limit cycles.

Abstract: A transmission scheme contemplates encoding and modulating digital data onto a discrete multi-tone signal having a total banwidth of at least 1.6 MHz. The modulation system dynamically updates the subcarriers used and the amount of data transmitted on each subcarrier during transmission (215, 217, 219). In one embodiment, the multi-tone encoding and modulation complies with the ATIS North American Asymmetric Digital Subscriber Lines standard. However, additional subchannels (a total of 512) and/or subchannel bandwidths of greater than 4.3125 kHz may be used. In this system, the subchannels occurring above frequencies set forth in the standard are treated similarly to those within the standard range in terms of subcarrier selection criteria. This system permits transmission of digital data at transmission rates of 6-55 Mbps over twisted pair lines at distances of 1200 meters on lines experienci ng significant crosstalk noise such as T1 or E1 (215, 21 7, 219) as well as at transmission rates of 10-50+Mbps over distances of 2000 m eters.

Title: System and method for managing multiple users with different privileges in an open metering system
Inventor: LEE DAVID K
IPC: G06F21/00
Filed: 1996-12-16
Granted: 2002-04-23
Abstract: A system and method of managing multiple users of an open metering system, wherein the users have different access privileges, includes the steps of providing a user password system for vault access; programming the vault with a plurality of transition states operatively relating to the user password system; assigning vault functional access to each user password first entered into the user password system; and performing a requested vault function when an entered user password under which the request is made has been assigned vault functional access for the requested vault function. The vault is manufactured in a first state in which the user password system is not activated and the activates the user password system upon entry of an initial user password which changes the vault to a second state that accepts requests for vault functions. The vault is changed to a third state from the second state wherein the user password system remains activated but another user password must be entered before a further request for a vault function is accepted. The requested vault function is rejected when the entered user password under which the request is made has not been assigned vault functional access for the requested vault function.

Abstract: A method for controlling a viscous heater  for a vehicle.  The vehicle has an engine, an engine cooling system for heating coolant, a passage, a  radiator and the viscous heater.  The radiator heats the passage using heat from the coolant.  The viscous heater uses the driving force of the engine to heat the coolant separately from the engine cooling system. The method includes a step of cutting off the transfer of the driving force of the engine to the viscous heater  when the engine is being started.  The method also includes a step of transferring the driving force of the engine to the viscous heater when the engine is running.

Title: Methods and apparatus for making ring-shaped parts out of a composite material, as well as preforms therefor
Inventor: COUPE DOMINIQUE
IPC: D04H1/46
Filed: 1996-06-18
Granted: 2004-04-06
Abstract: Preforms for producing annular parts of composite material are produced by winding a strip (1) of fibrous material around an elliptical mandrel (10) to produce an elliptical sleeve which can be cut obliquely, cutting taking plac e either before or after one or more densification steps. The cutting plane is inclin ed relative to the right cross section of the elliptical sleeve, and the inner and outer portions of the cut rings are machined to obtain circular elements. Such elements can produce annular parts of composite material having a reduced tendency to delamination under circumferential stress. The superposed layers are needlin g together during winding. A uniform needling density per unit area can be obtained by controlled displacement of the needle board (5) and of the elliptical mandrel (10) relative to each other as the mandrel turns, to compensate for the eccentricity of the cross section of the mandrel. These methods are particularly suitable for producing brake disk preforms.
