Abstract: A tissue analyte measuring device (2) includes a light source (4) structured to emit unpolarized light toward the skin surface of a subject, and a detector assembly (8) configured to receive light reflected the skin surface of the subject and the transcutaneous tissues of the subject, the detector assembly including a polarizing filter (12) and a number of light detector subassemblies (14). The polarizing filter is structured to filter out s-polarized light and pass only p-polarized light to light detector subassemblies. The light source is structured and positioned to emit the unpolarized light in a manner wherein the unpolarized light will exit the measuring device at a predetermined angle with respect to a normal to a light emitting plane of the measuring device, wherein the predetermined angle is an angle (the Brewster's angle) at which only s-polarized light will be reflected by the skin surface when the unpolarized light is incident thereon.

Abstract: A backward compatible enhancement to ATSC-VSB transmissions is provided to enable intra-field channel estimation for better channel equalization. One or more time-frequency waveforms are inserted into the transmitted signal with systematic time and frequency variation synchronized to the currently available field sync. A coherent demodulator may then directly estimate the channel frequency response. The power of the inserted waveform(s) is small compared to the existing 8-VSB signal, such that existing receivers will function as intended with only minimal degradation of performance.

Abstract: The invention relates to an optical system that particularly allows an improved detection of signal light propagating from a light source (1) through a flat glass substrate (11). SC-modes of this signal light that would normally be totally internally reflected at the backside (10) of the substrate (11) are coupled out by a first diffractive optical element DOE (21). To map all signal light leaving the substrate (11) onto a single target location (51), a focusing lens (31) and a second DOE (41) are disposed in the optical path behind the substrate (11). The DOEs (21, 41) may for example be a ID sinusoidal grating or a 2D blaze grating. The optical system may particularly be applied in an investigation apparatus for detecting multiple spots of a fluorescent sample material.

Abstract: The invention relates to a method for integrating a light guide (1) in or onto a support structure (3), wherein said parts (1,3) are molded and wherein during this molding and/or a subsequent cooling down process, shrink behavior of the respective parts (1,3) is controlled in such way that both parts (1,3) shrink incompatibly, at least temporarily and at least near their bordering areas, thereby causing the parts (1,3) to be separated and an air gap (10) to be formed between their respective separation surfaces. Separation of the parts (1,3) can be promoted by making the parts of materials having incompatible melting points and/or incompatible chemical bonding properties. Incompatible shrinkage can be stimulated by appropriate parts design, by applying materials having incompatible shrink behavior and/or by exposing the parts to different molding and cooling down conditions. The invention furthermore relates to a support structure with light guide and a device comprising such a support structure.

At least the challenge of this CRP is then stored.

Abstract: A recording device with loading means for loading a single record carrier comprises means for detecting not only that the loading means has reached its end position but also provides information that the loading means is currently loading or unloading the recording medium. This allows the recording device to start actions while the loading means is operating to prepare for the completion of the loading operation. A progress indication of the loading operation allows even better timing of actions by the recording device. A recording device may start filling a buffer once a certain progress of the loading operation is reached and the buffer size is sufficient to bridge the remaining duration of the loading operation. Thus the loss of information to be recorded is reduced.

Abstract: The acquisition of MR images while utilizing sub-sampling of the RF signals generated in the patient 21 to be examined is known. Such sub-sampling methods require at least two RF receiving coils which should not have a substantial component of their sensitivity vectors in common. According to the invention at least two coils 22a, 22b are used, a first one (22a) having its sensitivity vector extending substantially transversely of its physical coil plane whereas a second one (22b) has its sensitivity vector extending substantially parallel to its physical coil plane. The coils can thus be placed close to the surface of the patient without interfering with each other. They can be arranged in such a manner that their planes are oriented parallel to the main magnetic field Bo. Moreover, the coils can be arranged so as to overlap substantially, so that they provide the same field of view.
