Abstract:
An apparatus and method for data processing particularly useful in combining convolutions of the spreading code, scrambling code and channel response in order to construct a system transmission coefficient matrix, while maintaining the same circuit size and execution time relative to performing each convolution separately. One register for processing real channel response values and a second register for processing imaginary channel response values, are used for moving channel responses through the convolution. In place of multipliers, an optimized minimum number of adders connected in a pyramid configuration are used to perform the necessary multiplication of the codes, for simplicity of construction. By including the channel code transformation from binary representation to complex representation as part of the overall method, unnecessary adders are eliminated from the apparatus.
Abstract:
An apparatus and method for DFT processing using prime factor algorithm (PFA) on a selected number P of midamble chip values received by a CDMA receiver, where P has a plurality M of relatively prime factors F, and the DFT process is divided into M successive F-point DFT processes. The P data values are retrieved from a single input port memory and selectively permuted by a controller into parallel caches to optimize factoring with associated twiddle factors stored in parallel registers. The permuted inputs are factored in two or more parallel PFA circuits that comprise adders and multipliers arranged to accommodate any size F-point DFT. The outputs of the PFA circuits are processed by consolidation circuitry in preparation for output permutation of the values which are sent to memory for subsequent DFT cycles.
Abstract:
The invention involves a tilting device for emptying containers (2) of mixed-item loads, especially of pieces of airline luggage, which is placed along the course of a conveyor line (3), and at least one branch conveyor is bordering on the conveyor line with tilting arms located one behind the other in the direction of transport. The tilting arms can be swiveled laterally for emptying the containers (2) in each case around an axle (9) running in the direction of transport and horizontal to the extent possible, and at least two tilting arms for passing the containers (2) along between the conveyor lines (3) can be connected in a detachable way with a container (2). In order to create a tilting device for emptying containers that has an optimized operational throughput, it is proposed that the tilting arms are each to be arranged on a chassis (7), the chassis (7) are to be connected through a driven traction mechanism (4) into an endlessly-circulating chain, and the containers (2) are to be capable of being coupled and decoupled for the acceptance of, and the discharge to, the conveyor line through holding devices (20) located on the tilting arms, as well as the containers (2) resting in the coupled state on the movable tilting arms.
Abstract:
Through a valve arrangement for brake systems of automotive vehicles comprising an electronic antilocking and traction slip control including a two-circuit brake pressure generator (3) and an auxiliary pressure supply system (5) generating an auxiliary pressure proportional to the pedal force and, in traction slip control, generating an uncontrollable auxiliary pressure, either the brake pressure generator (1) or the auxiliary pressure supply system is capable of being connected to the wheel brakes (26-29). The non-driven wheel (HR, HL) of the vehicle is connected directly while the drive wheel (VR, VL) of the vehicle is connected, through an additional multi-way valve, to the brake pressure generator (1) and to the auxiliary pressure supply system (12). Moreover, the wheel brakes (27, 29) of the driven wheels (VR, VL), through additional multi-way valves (20, 21) for the traction slip control, can be directly connected to the auxiliary pressure supply system(5).
Abstract:
For the control of a brake unit for automotive vehicles, electric signals are generated dependent on the operation of the brake pedal. The signals are processed in an electronic circuit (8) and logically linked to sensor signals containing information on the brake power, the braking effect and/or on the rotational behavior of the individual wheels. Electrically actuatable wheel brakes (1, 2, 3, 4, 32, 33) equipped with an electric drive (M) are controlled by the generated signals. Through a second brake system, brake power is transmitted by the brake pedal (5, 5') either simultaneously or upon overcoming a threshold value to the wheels of one axle, preferably to the front wheels, i.e. front right, front left wheels (VR, VL), the brake power becoming, however, effective exclusively in the event of a fault or a failure of the electrical brake system or of the electric power supply.
