Abstract:
This method relates to the control of the information stream in a cell constituted by several radio channels (C.sub.1) and (C.sub.2), each connecting terminal stations (T.sub.1l to T.sub.1m) and (T.sub.2l to T.sub.2n) to a main station (1) of the cell. In order to assign the ascendent path of a radio channel to a terminal station, the main station transmits in this channel a code signal S.sub.o, whereupon the terminal stations transmit calls to be used in call time windows each with an associated priority level. The main station transmits, in answer time windows, code signals dependent upon the received signals: a code signal S.sub.3 if the received signal is a distinct call, to give a terminal station the authorization to use the ascendent path, or a sequence of code signals S.sub.1 or S.sub.2 if the received signal contains, simultaneously, several calls, or does not contain any call. Dependent upon each code signal S.sub.1 or S.sub.2 received and upon each bit of its address, each terminal station decides whether a new call has to be transmitted or is not to be transmitted, which terminates, according to a dichotomy process, by the transmission of a code signal S.sub.3 by the main station.
Abstract:
A recreational utility vehicle has a frame, four wheels, a pair of seats mounted laterally beside each other, a cage, a steering assembly, an engine, a front differential, a rear differential, an actuator selectively operatively connecting the engine to the front differential, and a vehicle drive mode switch for selecting between a first and second drive mode. When the first drive mode is selected, the actuator operatively connects the engine to the front differential, and when the second drive mode, the actuator operatively disconnects the engine from the front differential. An electric motor is operatively connected to the steering assembly. A steering control unit is electrically connected to the electric motor, determines an output torque to be applied by the electric motor based at least in part on a speed of the vehicle, and controls the electric motor to apply the output torque to the steering assembly.
Abstract:
A wheeled vehicle (10) has a power steering assembly. The vehicle can operate in an AWD mode and a 2WD mode. The degree of steering assist provided by the power steering assembly is determined from one of various steering maps (8A-8D; 114A-D). The steering map is selected based on whether the vehicle is operating in the AWD mode or the RWD mode and on a steering mode selected by a steering mode control switch (100) on the vehicle. A method of controlling a power steering assembly is also disclosed.
Abstract:
A monopole type antenna suitable for operating in cellular frequency bands, the antenna comprising: a conductive surface forming a radiating element and including an electrical connection zone; a compact conductive counterpoise including a connection zone; and a feed line comprising an antenna cable connected to the connection zones of said radiating element and of said compact counterpoise. In the antenna, said radiating element is in the form of an open loop having two branches both connected to the antenna cable and defining first and second radiating portions, each of the radiating portions is suitable for entering into resonance at at least one cellular frequency and extends in a main direction; and these two main directions are substantially parallel so as to operate parasitically and with coupling between the two radiating portions.
Abstract:
The invention features a method for detecting an increased likelihood of hyperhomocysteinemia and, in turn, an increased or decreased likelihood of neural tube defects or cardiovascular disease. The invention also features therapeutic methods for reducing the risk of neural tube defects, colon cancers and related cancers. Also provided are the sequences of the human methionine synthase gene and protein and compounds and kits for performing the methods of the invention.
