An extra-oral digital panoramic dental x-ray imaging system is disclosed for multi-layer panoramic and transverse X-ray imaging. The system includes an X-ray source and a digital imaging device capable of “real time” frame mode output. The source and imaging device are mounted in a mechanical manipulator defining the trajectory of a predetermined image layer. The imaging device communicates with a processor that generates a frames memory from which an image reconstruction mechanism composes the final images. For “real time” imaging, the frames memory is a fast data storage system such as RAM. The processing unit executes the reconstruction algorithms, allowing the system to selectively generate dental panoramic X-ray images, dental transverse x-ray images and dental tomosynthetic 3D images.

An optical reader for reading encoded microparticles. Each microparticle has an elongated body with an optically detectable code that extends along a longitudinal axis of the corresponding elongated body. The reader includes a plate that has a plurality of channels. The channels are configured to receive and align the microparticles so that the codes of the microparticles are in a common fixed orientation relative to each other. The reader also includes an illumination source for illuminating the microparticles on the plate. The codes in the microparticles reflect a portion of incident light and permit a portion of the incident light to pass through the microparticles thereby providing an output signal indicative of the code. The reader also includes a detection device that is configured to capture the output signal provided by the microparticles.

A convolution interleaver for processing a codeword which is derived from an input block of symbols using a redundancy-adding code (22) and which has more symbols than the input block, where the codeword has a sequence of interleaving units, each interleaving unit having at least two symbols, comprises an interleaving device (10). The interleaving device alters the sequence of interleaving units in order to obtain an interleaved codeword which has an altered sequence of interleaving units. In particular, the interleaving device does not alter the order of the symbols within an interleaving unit. However, the order of the interleaving units in the codeword is altered among one another or in respect of a preceding or succeeding codeword.

A waveform reproduction apparatus and process for carrying out waveform reproduction without delays. Waveform data expressing first and latter half portions of a musical tone waveform are stored on a storage device. In response to a tone generation start indicator, waveform data that express first half portions corresponding to the tone generation start indicator are successively read out and corresponding musical tone waveforms are formed. Following this, the waveform data that express latter half portions corresponding to the tone generation start indicator are successively read out and corresponding musical tone waveforms are formed. After the first half portions are successively read out and corresponding musical tone waveforms are formed, if the read-out of the waveform data that express the latter half portions corresponding to the tone generation start indicator is not completed in time, the formation of the musical tone waveforms is based on a specified segment set in the first half portion of the waveform data.

The present invention relates to a circuit (1) for biasing and reading out a bridge sensor structure (2). The circuit comprises at least two pairs of connection terminals (3), each pair adapted for connecting to complementary terminals of the bridge. The circuit comprises an excitation signal generator (4) for generating an excitation signal for biasing and / or exciting the bridge, in which the excitation signal is provided as a non-constant periodic continuous function of time. The circuit also comprises a detection circuit (5) for obtaining the sensor signal from the bridge sensor structure (2) by electrically connecting the detection circuit to any pair of connection terminals (3) while applying the excitation signal to another pair. The circuit comprises a switch unit (6) for switchingthe electrical excitation signal from being supplied to a first pair to another pair of the connection terminals and for switching the detection circuit from being connected to a second pair to another pair of the connection terminals, and a controller (7) for controlling the switch unit (6) to switch the first pair from being connected to the excitation signal generator (4) at a time when the generated excitation signal is in a predetermined signal range where the excitation signal value is substantially equal to zero.

A device for determining an actual cell state of a resistive memory cell having a plurality M of programmable cell states comprising a sensing circuit, a settling circuit, a prebiasing circuit, and a resistor coupled in parallel to the resistive memory cell, wherein the resistor is configured to reduce an effective resistance seen by the prebiasing circuit. The sensing circuit is configured to sense a sensing voltage of the resistive memory cell and output a resultant value in response to the sensing voltage which is indicative for the actual cell state. The settling circuit is configured to settle the sensing voltage to a certain target voltage representing one of the M programmable cell states. The prebiasing circuit is configured to prebiase a bitline capacitance of the resistive memory cell such the sensing voltage is close to the certain target voltage.
