Abstract: A transmitter for generating and transmitting frequency shift keying signals. The transmitter comprises a resonant circuit, a capacitor, a switch for coupling and decoupling the capacitor to the resonant circuit, a sensor and a controller. The controller includes an input for receiving a data signal. The controller actuates the switch to selectively couple the capacitor to the resonant circuit based on the state of the data signal. The sensor determines when the energy level in the capacitor is substantially zero and the controller synchronizes actuation of the switch with the substantially zero energy state of the capacitor. The transmitter also includes a circuit for efficiently supplying power to the resonant circuit in form the power pulses.

Abstract: The assembly and method are disclosed for the mechanical automated loading of cut cucumbers into jars. The cucumbers are sized in length and delivered to one or more cutter and loader stations where they are cut into slices or the like, and the slices are divided between a pair of pivot chutes. The pivot chutes are pivoted away from each other and into alignment respectively with a pair of jar chutes, the latter of which extend into the openings of the jars to be loaded. The cut cucumbers are delivered through the jar chutes at a substantial angle to both the plane of the opening of the jar and the axis of the jar, and toward the outer wall of the jars against which they are deposited. As each load is deposited into a jar, the jar is rotationally indexed in readiness for the next load, and the previously deposited loads are held against the outer wall of the jar by a mandrel which extends into the jar during the loading operation.

Abstract: An apparatus (30) for determining the minority carrier lifetime of a semiconductor sample (32) includes a positioner for moving the sample relative to a coil (44). The coil (44) is connected to a bridge circuit (42) such that the impedance of one arm of the bridge circuit (42) is varied as sample is positioned relative to the coil (44). The sample (32) is positioned relative to the coil (44) such that any change in the photoconductance of the sample (32) created by illumination of the sample (32) creates a linearly related change in the input impedance of the bridge circuit (42). In addition, the apparatus (30) is calibrated to work at a fixed frequency so that the apparatus (30) maintains a consistently high sensitivity and high linearly for samples of different sizes, shapes, and material properties. When a light source (34) illuminates the sample (32), the impedance of the bridge circuit (42) is altered as excess carriers are generated in the sample (32), thereby producing a measurable signal indicative of the minority carrier lifetimes or recombination rates of the sample (32).

Abstract: The invention relates to a method for production of three-dimensionally arranged conducting and connecting struc-tures for volumetric and energy flows. Various light-setting materials are used for the production of the layers. Upon exchanging the materials, those layer regions in which no setting occurred during the preceding setting process, are also filled with new material, such that, in the subsequent setting process, not only is the upper layer linked to the one lying directly beneath it, but also material of the upper layer is connected to the material of a layer lying below the penultimate layer. It is thus possible, within the layer sequence, to connect a structure with varying properties from layer to layer.

Title: Parallel correlator architecture
Inventor: CARLSON BRENT R
IPC: H03H17/02
Filed: 2001-01-17
Granted: 2008-09-23
Abstract: The present invention relates to real time spectral analysis of wide-band sampled signals, in particular to a method and system for real time digital spectral analysis of wide-band sampled signals using parallel processing techniques. The center frequency of each received wide-band signal is shifted by a small fraction e of its bandwidth. After sampling and digitizing, the wide-band signals are de-multiplexed into N parallel sample streams for parallel processing. The sample streams are digitally FIR filtered and sub-band signals are determined by decimating the sample streams by a factor of 2k.N;k = 0,1,..., wherein only every 2k.N th;k = 0,1,... sample is retained and the others are discarded. These sub- band signals may then be processed using various methods of spectral analysis such as cross-correlation, auto-correlation or phased array applications. Any finite-length FIR filter has a finite transition band. After decimation, the transition band outside sub- band boundaries will suffer aliasing, which causes signals to falsely appear as aliased signals within the sub-band. Shifting all spectral features in the wide-band spectrum with a frequency shift .epsilon. prevents false correlation of the aliased signals.

Title: Hydrophile silicone elastomer material used in particular for impressions
Inventor: HOWE FABIENNE
IPC: A61K6/90
Filed: 2000-04-05
Granted: 2007-12-11
Abstract: The invention concerns a silicone material crosslinkable into silicone elastomer by polyaddition reactions, useful in particular for impressions, for example dental. The invention aims at providing a material offering a compromise between the following characteristics: fluidity (in non crosslinked sate), hydrophily (in non crosslinked or crosslinked state) and high mechanical properties (in crosslinked state). The invention is characterised in that it consists in introducing into the crosslinkable silicone material: (i) a reinforcing siliceous filler in the form of a suspension obtained by subjecting the filler to a treatment in two stages by an agent providing compatibility (selected for example, concerning the first stage, among a silazane, a hydroxyl-containing siloxane, an amine, an organic acid; and concerning the second stage, among a silazane), by operating in the presence of a polyorganosiloxane with Si-alkenyl functions; and (2i) one or several non-ionic, ionic or amphoteric surfactants. Said silicone material is particularly useful for impressions, for example dental impressions and for making pads used in pad printing techniques.
