Abstract:
A digital input/output unit has a series of terminal points and visual display devices assigned to the terminal points for the display of the respective switching state. It also has an interface for the exchange of process data with a controller and an electronic circuit connected between the interface and the respective terminal points for converting the process data into corresponding switching signals and vice versa. The electronic circuit has an evaluation device for terminal point related signaling data received from the interface in order to activate a respective selected visual display device regardless of the current switching state. Alternatively, or in addition, the electronic circuit can have an evaluation device for a common signaling datum, which can be received from the interface, relative to the complete input/output unit in order to be able to jointly activate all visual display devices regardless of the particular current switching state.
Abstract:
A receiver or an integrated circuit (IC) incorporated therein includes a fast Fourier transform (FFT)-based (or hybrid FFT-based) sliding window block level equalizer (BLE) for generating equalized samples. The BLE includes a noise power estimator, first and second channel estimators, an FFT-based chip level equalizer (CLEQ) and a channel monitor unit. The noise power estimator generates a noise power estimate based on two diverse sample data streams. The channel estimators generate respective channel estimates based on the sample data streams. The channel monitor unit generates a first channel monitor signal including truncated channel estimate vectors based on the channel estimates, and a second channel monitor signal which indicates an approximate rate of change of the truncated channel estimate vectors. The FFT-based CLEQ generates the equalized samples based on the noise power estimate, one-block samples of the first and second sample data streams, the channel estimates and the monitor signals.
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:
Multi-user detection (MUD) performance is optimized to eliminate redundant use of power during processing. An overbuilt A-matrix, i.e., a system response matrix, is provided. The overbuilt A-matrix uses all possible codes, e.g., all codes identified in a candidate code list (CCL) provided by blind code detection (BCD). The overbuilt A-matrix is passed to the MUD which extracts only those rows or columns required for codes that have actually been received, thus eliminating the need to recompute whitening matched filter (WMF) outputs that do not correspond to the actually received code.
Abstract:
An electronic labeling system and method for uniquely identifying and labeling products. A dedicated memory device and an associated display device are attached to and associated with one or more of a group of products. Customer-specific data is downloaded to the memory device using a non-contact data transmission link and stored in the memory device. The stored data is then transmitted to the display device, which is, e.g., a highly flexible, thin device, such as e-paper, where the customer-specific data, such as customer name and address, assembly instructions related to the product, operating instructions related to the product, and/or any other data deemed useful with respect to the product, is displayed. The data displayed on the label/display can be updated as often as desired to ensure up-to-date information is being provided.
Abstract:
The present invention relates to a termination module comprising multiple contacts for the termination of cable wires at an insulation displacement contact and comprising a pressure piece with a screw, an intermediate piece and a base plate. The object of the invention, is to develop a termination module of the type in which cable wires having different wire diameters can be terminated in a wide range. It is achieved by a closed bifurcated contact connected as one piece over a connection plate 21 with insulation displacement contact 7 and a tapping 18, insulation displacement contact 7 being disposed inclinedly behind bifurcated contact 6.
Abstract:
A device for the hydraulic boosting of steering force comprises a cylinder having a working piston which is coupled with a steering rod assembly. The cylinder includes working chambers into which hydraulic pressure can be introduced by way of multi-directional control valves. The steering aid is designed as an accessory unit for a brake system with an auxiliary hydraulic energy supply and will be put into function only during vehicle standstill or at low vehicle speeds.
Abstract:
A method for reducing or substantially preventing formation of a trisulfide derivative of a polypeptide in a liquid medium containing the polypeptide ijn question comprises stripping the liquid medium with a gas, suitably a chemically unreactive gas such as nitrogen or argon.
Abstract:
The instant invention relates to a method of operating a portable electronic device and to an electronic device, especially a mobile radio telephone apparatus on which a dictating application for recording, storing, reproducing and/or processing speech input is executed. Depending on an automatically determined operating state of the dictating application, a display means of the portable electronic device displays a menu of functions of the dictating application, adapted to the particular operating state of the dictating application, the functions being selectable by a user by way of an input means of the portable electronic device.
Abstract:
A method for monitoring an automation unit with a control unit (3) and several terminals (1,2), whereby the terminal can adopt at least two status values. At least some of the previous status changes can be subsequently reconstructed. The control unit (3) receives a message telegram from one of the terminals (1, 2), whereby the one terminal (1, 2) outputs another message telegram only after it has received an acknowledgment signal (Q) from the control unit (3). The message telegram contains at least one first transition component (E01), which indicates a transition from a first state value to a second state value of the at least two state values, and contains at least one second transition component (E10), which indicates a transition from the second state value to the first state value of the at least two state values.
