Abstract: A data collector having a digital signal processing circuit that receives a digitized vibration signal, and performs processing steps to isolate high frequency pulses in the digitized vibration signal and quantify energy content of those pulses by detecting a peak negative value of the digitized peak-to-peak amplitude of the received vibration signal, and then using this peak negative value to compute a maximum peak-to-peak value of the received vibration signal. Periodically, the maximum peak-to-peak value and peak negative value are reduced in magnitude by a decay factor, such that the peak negative value and maximum peak-to-peak value decay over time. The decay factors used in computing the maximum peak-to-peak value and peak negative value are determined by the digital signal processing circuit and may be readily changed. As a consequence, high frequency processing performed by the digital signal processing circuit may be readily adapted to the particular frequency characteristics of the machine being analyzed for predictive maintenance, without modification of the analog circuitry of the data collector. The resulting maximum peak-to-peak value comprises a peak-detected digital output signal that may be stored and/or displayed to a user as a reflection of the high frequency content of the vibration signal, or frequency transformed for storage and/or display to a user.

Abstract: A method and apparatus for preventing current flow through the integral body diode of an electronic switch (e.g. MOSFET) in the secondary circuit of a synchronous rectifier. In a conventional synchronous rectifier, body diode current 31a 31b occurs during dead times 32a 32b. In the present invention, current steering pulses 40 are applied to the secondary circuit to oppose freewheeling current flow through the integral body diode. The current steering pulses produce a current that maintains the body diode in a reverse-biased state. Also, body diode current 31a 31b is prevented in the invention by short-circuiting a primary winding 19 of a transformer. The present invention prevents body diode conduction energy losses, as well as reverse recovery losses. The present invention is applicable to many different kinds of synchronous rectifiers such as current doubling rectifiers, center-tapped rectifiers, full bridge rectifiers.

Abstract: A dual frequency cholesteric display includes a pair of opposed substrates, wherein one of the substrates has a first plurality of electrodes facing a second plurality of electrodes on the other substrate. A dual frequency bistable cholesteric liquid crystal material is disposed between the substrates, wherein the material and the intersection of the first and second plurality of electrodes forms a plurality of pixels. By selectively applying high and low frequency voltages to the plurality of pixels, the high frequency voltage causes the material to exhibit one texture and the low frequency voltage causes the material to exhibit another texture. By adjusting a voltage amplitude value for each high and low frequency causes each pixel to exhibit a desired reflectance.

Abstract: A method of printing an ink or meltable ink layer which comprises dyes or pigments or other colorants. The ink or ink melt layer comprises compounds with functional groups capable of reacting with active hydrogen, and compounds with functional groups containing active hydrogen, or functional groups capable of conversion to active hydrogen containing groups. An image is printed onto a substrate, at a relatively low temperature, so that the ink is not activated during the process of printing on to the medium. The image is subsequently transferred or permanently fixed on the substrate by the application of heat and pressure, which activates the ink, and bonds the colorant to the substrate. The reactive compounds may be blocked with blocking agents which are removed by the application of heat or other energy during activation of the ink.

Abstract: A system and method for increasing capacity of a cellular system by reducing call overhead processing and transmission congestion previously required in updating a subscriber's mobile station data position as the subscriber moves among locations within a geographic area served by a network service provider is presented. A predetermined N number of copies of mobile station subscriber data is distributed among multiple Visiting Location Registers (VLRs) within the area served by a cellular system. Unlike previous systems, when mobile stations traverse location boundaries, the current VLR corresponding to the current location does not need to update the subscriber data if that data has not changed since the subscriber was last in that location.

Abstract: A method of printing a liquid ink which is produced from a heat activated dye which is selected from a limited group of dyes which are capable of transfer at low energy. A printer which uses liquid ink, such as an ink jet printer, prints an image onto an intermediate substrate medium. The dyes contained in the ink are not substantially activated during the process of printing on to the medium. The image formed by the printed ink is transferred from the medium to a final substrate by the application of heat and pressure for a short period of time to activate the ink. The dye and dispersing/emulsifying agent(s) are selected from a limited group to produce an ink which permits thermal transfer at low energy, with the resulting image, as deposited on the final substrate, having an optical density of 1.0 or greater.

Abstract: Heat sensitive inks are disclosed that reduce kogation in the print heads of thermal ink jet printers. The ink incorporates heat sensitive colorants/sublimation dye solid particles that are larger in size but smaller in quantity than particles that are not heat sensitive at the operating temperature of the heating elements. The smaller particles do not contribute to kogation, whereas the larger colorant particles contribute to kogation if they contact the heating element of the print heads. The smaller particles move more rapidly toward the heating element as the thermally induced bubble collapses and provide a barrier between the heating element and the heat activated or heat sensitive colorants/sublimation dye solids (hereinafter heat sensitive colorants).
