Abstract: A modulated optical radiation field (I) whose modulation amplitude and temporal phase depend on the local position can be detected with a plurality of pixels 1. Each pixel 1 consists of a transducing stage (T) that converts incoming light (I) into a proportional electric signal, a sampling stage (S), two subtraction/summation stages (SUB1, SUM1; SUB2, SUM2), and an output stage. Each pixel can be addressed individually. The optical radiation field (I) is locally sensed and sampled at a frequency that is four times the wavefield's modulation frequency. The subtraction/summation stages (SUB1, SUM1; SUB2, SUM2) accumulate differences of two samples per modulation period, separated by half the period, during several averaging periods; the two stages are time shifted with respect to each other by a quarter period. The resulting two output signals are employed for the determination of the local envelope amplitude and the temporal phase. These pixels 1 can be realized with circuits that consume very little electric power require small areas, enabling the realization of large numbers of pixels in linear or two-dimensional array sensors.

Abstract: A two-dimensional, temporally modulated electromagnetic wavefield, preferably in the ultraviolet, visible or infrared spectral range, can be locally detected and demodulated with one or more sensing elements. Each sensing element consists of a resistive, transparent electrode (E) on top of an insulated layer (O) that is produced over a semiconducting substrate whose surface is electrically kept in depletion. The electrode (E) is connected with two or more contacts (C1; C2) to a number of clock voltages that are operated synchronously with the frequency of the modulated wavefield. In the electrode and in the semiconducting substrate lateral electric fields are created that separate and transport photogenerated charge pairs in the semiconductor to respective diffusions (D1; D2) close to the contacts (C1; C2). By repetitively storing and accumulating photocharges in the diffusions (D1; D2), electrical signals are generated that are subsequently read out for the determination of local phase shift, amplitude and offset of the modulated wavefield.

Abstract: The pixel for use in an image sensor comprises a low-doped semiconductor substrate (A). On the substrate (A), an arrangement of a plurality of floating areas, e.g., floating gates (FG2-FG6), is provided. Neighboring floating gates are electrically isolated from each other yet capacitively coupled to each other. By applying a voltage (V2−V1) to two contact areas (FG1, FG7), a lateral steplike electric field is generated. Photogenerated charge carriers move along the electric-field lines to the point of highest potential energy, where a floating diffusion (D) accumulate the photocharges. The charges accumulated in the various pixels are sequentially read out with a suitable circuit known from image-sensor literature, such as a source follower or a charge amplifier with row and column select mechanisms. The pixel of offers at the same time a large sensing area, a high photocharge-detection sensitivity and a high response speed, without any static current consumption.

Abstract: A photo sensor exhibiting low noise, low smear, low dark current and high dynamic range consists of a pinned (or buried) photodiode (PPD) with associated transfer gate (TG), a reset circuit (3) and a device (SL) with sub-linear voltage-to-current characteristic. The exposure cycle is started by reverse biasing the buried photodiode to its pinning potential and by setting the transfer gate (TG) to a non-zero skimming potential. Photo-generated charge carriers start to fill the buried photodiode; if illumination intensity is high, excessive photocharges are flowing over the transfer gate (TG) to the sensing node. Because of the sub-linear device (SL) connected to the sensing node, the voltage at the sensing node is a sub-linear function of the illumination intensity, and hence the dynamic range of the pixel is increased. The voltage at the sensing node (Se) is read four times, namely before exposure, with the spilled-over photocharge, after reset, and after the photocharge in the buried photodiode has been transferred to the sensing node. This allows correlated multiple sampling techniques to be employed for eliminating reset noise. Because of its compact size, the photo sensor can be employed in one- and two-dimensional image sensors fabricated with industry-standard CMOS or CCD technologies.

Abstract: A compressor includes a casing defining a generally cylindrical flow passage, a rotor carrying at least one set of rotor blades, at least one set of stator blades, and anti-stall casing treatment. The casing treatment includes an annular recess in the casing for removing low momentum flow adjacent the tips of the rotor blades, and returning the flow to the generally cylindrical flow passage upstream of the point of removal. A plurality of curved guide vanes are located within the annular recess so as to define an annular inlet downstream of the vanes and/or an annular outlet upstream of the vanes. Each guide vane projects radially inwardly from the casing towards a free end which is exposed at or near the mouth of the recess to define a series of curved channels within the recess adjacent the annular inlet and/or the annular outlet.

Abstract: A method for the production of inserts or the like is shown, with a patient or also a healthy person standing/walking/sitting/lying/biting in a defined position and/or movement with the body part to be fitted (foot, buttocks/back, teeth) on/over an electronic measuring arrangement for two- or three-dimensional measurement of the forces (pressures) acting on the measuring arrangement. The output signals of the measuring arrangement corresponding to the pressure-force distribution under the body part in the two- or three-dimensional pattern of the pressure-force distribution are relayed to a computer and compared with a stored set of desired values (wanted or ideal data). The differences between the distribution patterns are transformed into control signals for controlling an apparatus for the manufacture of the inserts or seating furniture surfaces, lounging furniture surfaces, dental prostheses, in such a way that upon addition of the (virtual) pressure force compensation distribution in accordance with the form (height) and/or rigidity of the inserts or the like to be manufactured to the actual pressure force distribution pattern, the desired pressure force distribution pattern essentially results.
