Abstract: A demodulation frequency plan for use in a global positioning system (GPS) receiver, having three demodulation stages for L1 and L2 signal channels, in which identical local oscillator frequencies are used in the L1 and, L2 channels at each demodulation stage, to minimize phase error differences between the two channels. The third stage provides an output at an intermediate frequency high enough to carry the full information bandwidth, thereby simplifying digital sampling of the signal, which is also performed in the third stage. Sampling is performed at a high enough rate to facilitate subsequent conversion to baseband. Moreover, the sampling rate is a binary multiple of the intermediate frequency, and this binary relationship further simplifies conversion to baseband.

Abstract: It is endeavoured further to reduce the size of medium-voltage switchgear, but on the other hand it is intended to improve the switching power. To this end, it is necessary to adapt the associated drives for medium-voltage switchgear to these new conditions. The invention shows a means by which a snap-action drive for medium-voltage switchgear is designed with few individual parts which can be housed in a U-shaped supporting rack 21. Two driveshafts 1 and 1' are provided, which are designed as hollow shafts and in which thrust rods 12, 12' unlock thrust locking bolts 18, 18', by means of an operating device 37 via guide pieces 13, 13' which are located in the driveshafts 1 and 1', which results in a force-fitting connection being produced between the drive and the moving contacts. The operating device 37 is installed together with a locking plate 23 such that incorrect handling is prevented. Such a snap-action drive can be used in medium-voltage switchgear, preferably in metal-encapsulated, compressed-gas-insulated switchgear. <IMAGE>

Abstract: The invention relates to a method for generating a low resolution gray-scale pattern, such as 8 x 8 dots/character representing a high resolution original character image, such as 88 x 88 dots/character. The microprocessor generates a sampling pattern having plural sampling windows arranged in rows and columns, such as 8 x 8 sampling windows, in accordance with a ratio of the low resolution to the high resolution. The size of the sampling pattern with the 8 x 8 sampling windows is equal to the size of the character box or matrix of the original character image. At first, the position of the entire sampling pattern is shifted on the original character image to detect an optimum or calibrated position in X and Y direction at which the total number of black pels on a group of pel lines, eg five pel lines, at a center portion of all rows or all columns is the largest value. Secondly, the position of a selected row(s) and/or column(s) of the sampling pattern at the calibrated position is shifted to the position at which the number of black pels on the five pel lines at the center portion of the selected one row or one column has the largest value.

Abstract: Productivity in electronic printer incorporating finishing activities, and operation in a job streaming mode, are enhanced by utilizing software to calculate and predict the minimum delay (corresponding to minimum skip pitches) in successive jobs requiring finishing activities such as binding and stapling. Printing and collating of sets of original scanned documents are controlled so that collated sets are successively presented by the printer to the finisher nearly coincident with conclusion of the finishing activity being accomplished for a current job. Additional software allow job scheduling for jobs involving complex pitch time delays created by scanning simplex and duplex documents returned in random order. For this case optimum delay time is the cumulative finishing hardware delays as well as imaging/paper path delays. Still another feature is a predictive algorithm which is used to increase reliability of printer components by cycling down the printer between jobs in situations where the finishing activity for a current job requires an extraordinarily long time to complete compared with the cycle down/cycle up time of the printer.

Abstract: Polarized light pulses are input to an optical modulator (16) formed by an electrooptic crystal. The polarization state of the input light is changed in accordance with an electrical signal (i.e., voltage) applied to the optical modulator (16). Receiving the light output from the optical modulator, a polarization interferometer (18) produces an interference fringe on the input surface of a photodetector (20) such as a one-dimensional CCD. Based on an output signal of the photodetector (20), a processing device (22) calculates a pitch and a movement distance of the interference fringe to determine the voltage. A waveform of the electrical signal is measured while being sampled.

A force diverting mechanism (166,172) is responsive to the force applied to the handle exceeding a predetermined force to provide the surgeon with an indication of the excessive force and protects the jaw components at the distal end of the surgical forceps. A suction passage is formed in the forceps for aspirating cut tissue and assisting the positioning of tissue between the jaws, and suction can be produced continuously or controlled via the handle. The handle includes locking and latching mechanisms (184,178) to hold the jaws in a closed position.
