Abstract: A controlled process and suitable apparatus are described for controlled continuous microwave digestion of samples of materials to prepare them for subsequent analyses or other chemical operations. The material to be analyzed, in finely divided form and mixed with digesting liquid, which is usually a strong acid, is charged as a slug into a flowing liquid carrier stream, usually water, which stream, containing the slug, is passed in a tube through a zone in which the tube and contents are subjected to microwave radiation, to heat the digesting liquid and the material to be digested to promote the digestion. The process and apparatus are like those of U.S. patent 5,215,715, modified by inclusion of detecting and controlling steps and corresponding apparatus components to detect a condition of the flowing liquid without physically contacting it, as by determining the dielectric constant of contents of the tube, or a related property of such contents at one or more locations of the tube, usually outside the microwave zone, and controlling operations of the process and apparatus accordingly. Such controlled or controllable operations include charging of subsequent slugs to the system, feeding digested slugs or portions thereof to autosampler means, and backwashing of a filter, and in such operations the controlling means is preferably microprocessor or computer means that is activated by signals from the detection means and automatically operates appropriate valves, pumps and autosampling means. Also within the invention is a procedure for converting a manual process, such as that described in U.S. patent 5,215,715, to an automatic one.

Abstract: A magnetic field enhanced single wafer plasma etch reactor (60) is disclosed. The features of the reactor include an electrically-controlled stepped magnetic field for providing high rate uniform etching at high pressures; temperature controlled reactor surfaces including heated anode surfaces (walls and gas manifold) and a cooled wafer supporting pedestal/cathode (70,72); and a unitary wafer exchange mechanism (74) comprising wafer lift pins (79) which extend through the pedestal and a wafer clamp ring (78). The lift pins and clamp ring are moved vertically by a one-axis lift mechanism (140) to accept the wafer from a co-operating external robot blade (76), clamp the wafer to the pedestal and return the wafer to the blade. The electrode cooling combines water cooling for the body of the electrode (70) and a thermal conductivity-enhancing gas interface between the wafer and electrode for keeping the wafer surface cooled despite the high power densities applied to the electrode. A gas feed-through device (114, 175, 176) applies the cooling gas to the RF powered electrode (72) without breakdown of the gas. Protective coatings/layers (81,83) of materials such as quartz are provided for surfaces such as the clamp ring and gas manifold. The combination of these features provides a wide pressure regime, high etch rate, high throughput single wafer etcher wich provides uniformity, directionality and selectivity at high gas pressure, operates cleanly and incorporates in-situ self-cleaning capability.

Abstract: The figure shows a speech transmission link. This leads from a telephone (11) of a private network (13) via exchanges (14, 17) to a mobile node (19) with an antenna (20) and via a radio link (22) to a mobile telephone (12). A mobile (31) and a stationary measuring unit (32) which are disposed near to the telephones (11, 12) are used to evaluate the given transmission quality. The one measuring unit (31, 32) transmits a pre-defined sequence of human speech, prefixed by a synchronisation pattern, as a test signal. The respective other measuring unit (32, 31) recognises the synchronisation pattern and thereby defines the starting time of the following sequence. This sequence is divided up into a multiplicity of respective intermediate values in that time intervals are formed and their sound characteristics are digitised. All of the intermediate values are finally evaluated by a neural network in such a way that an evaluation of "quality good, average or poor" understandable to humans is achieved at the output of said network. It is important here that the neural network is first trained using data evaluated by test persons. <IMAGE>

Abstract: In forming a plano-convex lens from a column-like lens blank by heating the blank to a temperature higher than the transition temperature thereof and by pressurizing an upper die with a closed space formed between the blank and the upper die, there are alternately repeated operations of pressurizing the upper die and stopping the application of pressure thereto. Through the control of the amount of displacement of the upper die, the maximum pressure of gas in the closed space at each pressurizing step is so controlled: to be sufficiently low with respect to the surface viscosity of the blank such that no local concave deformation in the surface of the blank is produced; and to be sufficiently high such that gas caught in the closed space is discharged during each step of stopping the application of pressure.

Abstract: A method of tissue compression is disclosed herein where the device to cause such compression is composed of a fastener bar and receiver. The device has the capability to self-adjust to tissues of varying thicknesses to cause hemostasis. This tissue gap variability allows for compression of regions of tissue where thick and thin tissue are both present. This variability also enables the same device to be used on a wide variety of tissues of different thicknesses. The tissue fastener bar of this invention contains a series of cut-out portions which distribute the compressive forces along the device in an alternating, staggered manner. The receiver is of a generally U-shaped configuration with the fastener bar being contained at least partially within the U-shape. Compression occurs between the side walls of the receiver and the fastener bar and variability in gap is accomplished by flexure of the side walls of the receiver. Varying side wall flexure is enhanced by cut-out portions in the receiver which allow each segment to flex somewhat independently. A number of options also exist for configuration of the fastener bar and/or receiver with the same basic method of compression being unchanged.

Abstract: Motion vectors are determined between a current frame and a preceding frame within a frame duration by employing a time-sharing multi-tier hierarchical motion estimation approach, wherein the candidate blocks being grouped into a multiple number of hierarchical search areas. The motion vector determination scheme is initiated by performing a motion estimation of a highest hierarchy for all of the search blocks; and an error function and a motion vector of the highest hierarchy are stored. Subsequently, motion-estimation of a lower hierarchy is performed for each of the selected search blocks which have the error functions greater than the threshold value of the highest hierarchy. In the next step, the error functions of the highest and the lower hierarchies are compared for each of the selected search blocks and a smaller error function is selected therefrom to thereby update each of the stored potential motion vectors with the motion vector corresponding to the selected error function. The updating process is repeated for the next hierarchies and the stored potential motion vectors are provided as the motion vectors of the current frame when updating process for the stored potential motion vector for a predetermined lowest hierarchy is accomplished or the frame duration is exhausted.

Abstract: A system for transmitting information over an OFDM channel using phase shift keying encoding employs a bit mapping encoder to reduce the crest factor (ratio of peak voltage to RMS voltage). For a 16 subchannel OFDM system using QPSK encoding, a first set of four symmetrically positioned pairs of subchannels is used to encode two bits of information on each subchannel. A second set of four symmetrically positioned pairs of subchannels is used to encode only one bit of information on each subchannel, with the resultant phasor for each pair of the second set of pairs of subchannels being orthogonal to the resultant phasor for one of the pairs of the first set of subchannels. With this arrangement, the crest factor is reduced.
