    Abstract: An interface arrangement including the cascade connection of a differential pre-amplifier (HPA1, HPA2) and a comparator (DA), and generally known as fast Low Voltage Differential Signal LVDS­ circuit for interfacing electronic chips. The current standards for such a LVDS circuit specify a minimum switching threshold voltage for the small differential input signal, while the common mode input signal varies over a very large range, both at a very high frequency. This is achieved owing to the fact that the differential pre-amplifier comprises a first (HPA1) and a second (HPA2) half pre-amplifier, each receiving the arrangement inputs (INN, INP) in an opposite way. Each half pre-amplifier (HPA1/HPA2) having first input inverter means (NN1, PN1) coupling an input (INN/INP) to an output (OUT1/OUT2) thereof, and second input inverter means (NP1, PM1, PM2; PP1, NM1, NM2) coupling the other input (INP/INN) to the output via current mirror means (PM1, PM2; NM1, NM2). The output current of the second input inverter means is thereby inverted with respect to the output current of the first input inverter means. To obtain a controlled gain, the half pre-amplifier further includes a short-circuited inverter.

    Abstract: The digital word equaliser having a receiver (TP) processing the pulse response, and a transformer process providing a minimum phase. The filtered signal received preserves equality between auto correlation of received and filtered signal and an equalisation process is applied to equalise the filtered signal taking account of the transformed pulse response.

    Abstract: A direct conversion receiver has a compensation module (MDM) envelope (PD2) and alternating signal (PD1) detectors with subtracter (CMP) and sampler (SAH) connected between the input (BE) from a conversion stage and output (STR) to a programmable gain amplifier (PGA) to create a compensation signal (SCP)

    Abstract: The enclosure assembly comprises a stationary member including at least two substantially parallel sidewalls, the sidewalls, the sidewalls partially defining a cavity in which the fingerprint sensor is disposed. An access piece, configured to move relative to the stationary member, has a surface area larger than the surface area of the fingerprint sensor and further includes a conductive portion electrically coupled to ground. A movement apparatus is preferably mechanically coupled to the stationary member and the moveable access piece. The movement apparatus is configured to maintain the moveable access piece in a position covering the fingerprint sensor and yet to allow motion of the moveable access piece relative to the stationary member so as to expose the fingerprint sensor. According to another embodiment, a method for enrolling a composite image of an object using a fingerprint sensor is provided. According to an embodiment, the method comprises the steps of receiving a finger disposed over a fingerprint sensor in a first stationary position; capturing a first image of a first portion of the finger with the fingerprint sensor; causing the finger to be repositioned over the fingerprint sensor in a second stationary position; capturing a second image of a second portion of the finger with the fingerprint sensor; and constructing a representative image of the finger from the first and second images.

    Abstract: The invention relates to a method for producing image sensors on the basis of TFA technology including of an amorphous thin-layer system that has been applied on a crystalline ASIC. The inventive method enables the production of image sensors on the basis of TFA technology, which improve the picture quality at low luminous intensity by reducing the dark currents. The photodiodes in the thin-layer material that are configured as pixels are linked with transistor structures in the crystalline ASIC via back electrodes. The transistor structures have particularly low leakage currents due to implantation technology or optimization of the production process.

    Abstract: The receiver has a unit (17) for compensating a received signal with a frequency offset from a frequency offset estimation unit to form a compensated received signal where the frequency offset estimation unit includes a part for determining phase shift. A determining unit obtains a timing reference for the received signal by cross-correlation (19) of the compensated received signal with a known training sequence. Independent claims are also included for the following: (a) an orthogonal frequency division multiplex (OFDM) telecommunication system including the receiver (b) a method for processing a received signal including a carrier modulated with a known training sequence (c) a method for obtaining timing reference from a received signal including a carrier modulated with a known training sequence.
