The automation system includes one or more terminals (1, 2), each of which can assume two or more states and each of which outputs a monitoring message that depends on the two or more states, and a control unit (3) that reads in the monitoring message from the one or more terminals (1, 2).

In order to be able, even subsequently, to reconstruct at least some of the preceding state changes, the monitoring message contains, in addition to each state value, at least one additional component (S1_Z, S2_Z; S1_OV, S2_OV) whose value is changed during a transition of the state value and which is reset to an initial value when a monitoring message is output.

Abstract: A wireless transmit receive unit (WTRU) recovers data from a plurality of data signals received as a received vector. The WTRU determines data of the received vector by determining a Cholesky factor of an N by N matrix and using the determined Cholesky factor in forward and backward substitution to determine data of the received data signals. The WTRU comprises an array of at most N scalar processing elements. The array has input for receiving elements from the N by N matrix and the received vector. Each scalar processing element is used in determining the Cholesky factor and performs forward and backward substitution. The array outputs data of the received vector.

Abstract: A method and an engineering system that reduce the configuration complexity with regard to a possible expansion of the automation device are provided. The automation device includes slave units and a master unit (7, 15) connected to the slave units via a bus. The slave units include one or more slave units (11, 12, 16, 17) and one or more reserve slave units (13, 18). The configuration of a reserve slave unit (13, 18) enables the master access time interval (20) and the slave access time intervals (21, 22, 23) to be expanded for a possible expansion of the automation device. As a result, a configured automation device of this type can be expanded by an additional slave unit without additional configuration or reconfiguration.

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: A method for configuring or reconfiguring an automation device and an automation device suitable for a configuration or a reconfiguration are provided. The automation device has a programmable controller (14) with a CPU unit (14a) and decentralized peripheral devices (16, 17, 18).

As a result, it is not necessary for centralized and/or decentralized peripheral modules to adopt a controlled (safe) state, which means that control can be resumed immediately after the reconfiguration.

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.
