The present invention provides an RFID transponder that includes a state holding cell (24) that maintains the present state of the RFID transponder during temporary losses of power. After power is restored to the RFID transponder, the state holding cell restores the present state to the RFID transponder so that transactions with an RFID interrogator can continue without having re-transmit redundant commands. The RFID transponder further comprises an RF front end (14) adapted to receive an interrogating RF signal. An analog circuit (18) is coupled to the RF front end and is adapted to recover analog signals from the received interrogating RF signal. The analog circuit provides state information defining a desired state of the RFID transponder corresponding to the analog signals. A digital state machine (20) is coupled to the analog circuit and adapted to execute at least one command in accordance with the state information. A memory (22) is coupled to the digital state machine and is adapted to store and retrieve digital data responsive to the at least one command executed by the digital state machine. A power capacitor (16) is coupled to the RF front end and derives a voltage rectified from the interrogating RF signal to charge the power capacitor. The power capacitor thereby provides electrical power for the analog circuit, the digital state machine and the memory. The state holding cell (24) is coupled to the analog circuit and the digital state machine and is adapted to maintain the state information during a loss in power provided by the power capacitor due to lapse in receipt of the interrogating RF signal by the RF front end.

Systems (500) and techniques to track deferred data transfers on a system-interconnect bus (515). A deferral response initiates storage of information corresponding to the response and tracking of progress for a requested data transfer. A master device, such as a bus adapter (300), may include a split-transaction repository (220), timers (230), and split-transaction monitor. The master device may include components, and may be designed to handle split responses as defined by a Peripheral Component Interconnect Extended standard.

A system and method is provided for controlling the mode of operation in a UWB receiver. In one variation, the system and method determines the mode of operation by reading a set number of samples of the signal, estimating mode parameters, calculating a mode probability, and then transitioning in a finite state machine between a track and an acquisition state depending on the value of the mode probability. Exemplary versions of the mode controller include a signal to noise ratio calculator, a signal and noise power estimator, and an AGC initialization circuit.

There is a need for a cheaper method of producing bleached TMP and CTMP without impairing the properties of the pulp. This is made possible by the present invention, which relates to a method of producing said pulps in which finely divided lignocellulosic material is defibrated after pretreatment and the resultant pulp is bleached in the form of a suspension with bleaching agent that increases the anionic charge of the pulp fibres, whereafter the pulp suspension is cleaned and then possibly further treated, for instance bleached, characterised in that the defibration is effected with the aid of a) a refiner that has counter-rotating refining discs while using an extra high temperature (HTDD), or b) a refiner that has a single rotating refining disc(s) having a single refining zone or two parallel refining zones, while using an extra high temperature and while rotating the disc(s) at an extra high speed (RTS), and in that the cleaning treatment comprises first screeming the pulp suspension and them hydrocyclone cleaning said suspension, wherewith the reject obtained with each cleaning process is treated individually and the treated reject is returned to the advancing pulp suspension.

A system and a method are provided for matching the color of a target sample at a remote location. The system has a first computer that is operative to receive and transmit target spectral data at a first location. A second computer in the system is located at a second location remote from the first computer. The second computer is operative to receive the target spectral data or formula identifier from the first computer. The system includes a database including a plurality of data sets. Each data set has at least spectral data corresponding to standard samples. The system also has software capable of searching the database using the target spectral data as search criteria and returning a match with a data set having standard spectral data that matches the target spectral data. The system optionally has a device that can sense the target spectral data of the target sample and input that target spectral data into the first computer, optionally also non-spectral data and QC capability.

The invention relates to an LCD display panel consisting of a plurality of LCD display modules (2) which are arranged next to and above each other, two directly adjacent LCD display modules (2) overlapping each other in a shingle-like manner in an overlap area. In this way, control circuits arranged in a first edge area of each LCD display module (2) are covered. An illuminating element (30) or a light deflecting element arranged between the two LCD display modules (2) compensates for the shading of the rear illuminating device (24).

The invention relates to an extremely flat and compact hybrid collector comprising a photo-voltaic collecting area facing the sun and having an active layer, a thermal collecting area which is arranged under the photo-voltaic collecting area, and thermal insulation which is located under the thermal collecting area. The extremely compact and flat structure is obtained by arranging the carrier layer of the active photo-voltaic layer as the upper outer layer of a sandwich structure, and by arranging the thermal insulation which is embodied as a corrugated gastight cardboard structure as the lower outer layer of said sandwich structure.

A linear beam device (10) having a multi-stage depressed collector is provided with means that quickly removes the total voltage across the collector electrodes (22-32) upon detection of an arc between the collector electrodes. The linear beam device (10) comprises a cathode (12) and an anode (16) spaced therefrom that are operable to form and accelerate an electron beam. A collector having a plurality of successive collector electrodes (22-32) is arranged downstream from the anode (16) to collect electrons of the electron beam. At least one power supply (42, 52, 62, 72, 82) is coupled to the collector and provides a plurality of distinct voltage levels to respective ones of the collector electrodes (22-32). The power supply (42, 52, 62, 72, 82) comprises a plurality of serially coupled filter capacitors (46, 56, 66, 76, 86), with each one of the filter capacitors (46, 56, 66, 76, 86) being charged to a respective difference (V-V5) between adjacent ones of the distinct voltage levels. A crowbar circuit (40) or other means is coupled across the plurality of filter capacitors (46, 56, 66, 76, 86). The crowbar circuit (40) or the other means reduces the total voltage across the plurality of filter capacitors (46, 56, 66, 76, 86) to zero upon detection of an arc between any two of the collector electrodes (22-32). According to an embodiment of the invention, the power supply further comprises a plurality of diodes (48, 58, 68, 78, 88) respectively coupled across the plurality of serially coupled filter capacitors (46, 56, 66, 76, 86). The diodes (48, 58, 68, 78, 88) prevent reversal of voltage of a corresponding one of the filter capacitors (46, 56, 66, 76, 86) upon operation of the crowbar circuit (40) or other means.
