Abstract: In a burst mode digital communication system, a preamble containing a predetermined bit pattern and a digital signal are modulated upon orthogonal carriers and transmitted in a series of burst signals. At a distant end of the system, the preamble and the digital signal are noncoherently detected with locally generated orthogonal carriers having the same frequency as the transmitted orthogonal carriers to produce in-­phase and quadrature signals. First and second correlators are provided to perform a correlation calculation between a locally generated bit pattern and the in-phase signal and to perform a correlation calculation between the local bit pattern and the quadrature signal. A phase error of the local carriers with respect to the transmitted carriers is detected from the outputs of the first and second correlators. A clock phase error of a locally generated clock pulse with respect to symbols contained in the transmitted burst signals is detected from one of the outputs of the correlators. Power level detector is connected to the outputs of the correlators for detecting a power level of the received burst signals. The carrier and clock phase error detection as well as the power level detection are performed in a parallel fashion, allowing a reduction of the amount of information contained in the preamble.

Abstract: A semiconductor switch, and in particular one comprises by a power integrated-circuit device, is protected against load voltage surges. This is done by means which supply current to a connected load device only in response to the occurrence of a voltage surge across said load device. Thus an alternate current-­carrying path is provided that is activated only in response to the occurrence of such surges. This alternate path is independent of and separate from the connection that extends between the device and its power supply source. In addition, circuitry can be connected to the device to limit the portion of the surge voltage that can appear across critical elements of the device.

Abstract: A technique for reconfiguring in the field postage meters having a set of features that may be selectively enabled or disabled by software. The technique provides security so that the meter company will always have a correct record of the configuration of the meter (10) in the field. The meter (10) is capable of being put into a configuration mode by suitable entries from the keyboard (14), in which mode it is inhibited from printing postage. The meter (10) has a storage register (26) for a current or old meter type, and can receive a desired new meter type via keyboard (14) entry. The meter (10) generates an encrypted configuration request code that is partially based on the values of the old and new meter types. The configuration request code, when communicated to the data center computer along with other validating identification information, is checked by the data center computer which generates the configuration request code using the same algorithm. 
If the two values agree, the data center computer generates an encrypted configuration enable code. This is communicated to the meter (10), which receives the computer generated configuration enable code and also generates an internal configuration enable code using the same algorithm as the data center computer. If the configuration enable codes agree, the meter (10) overwrites the old meter type number with the new meter type number, thereby reconfiguring the meter (10).

Abstract: A paper handling apparatus 10 includes a plurality of paper receiving trays 12, 14, 16, 18 arranged vertically in close proximity to one another with a single paper feeding mechanism 20 provided to operate with all of the trays 12, 14, 16, 18. The paper feeding mechanism 20 moves vertically to selectively engage any selected one of the plurality of trays 12, 14, 16, 18. The vertical arrangement of the trays 12, 14, 16, 18 dictates that the trays are horizontally moveable between a first unselected position, where the trays are substantially vertically aligned with the one another, and a second selected position where the tray is horizontally moved to intersect the vertical path of the paper feeding mechanism 20. Horizontal movement of the trays 12, 14 16, 18 is effected by a single electric motor 28 rotatably attached to a shaft 30, which carries a series of gears 32, 34, 36, 38 that interact with a corresponding rack 40, 42, 44, 46 disposed on each of the trays 12, 14, 16, 18, respectively. A transmission 48 links the motor 28 to the gears 32, 34, 36, 38 to selectively drive one of the gears and move one of the trays between the selected and unselected positions.

Abstract: A process and a device are used for calibrating a first high-frequency field strength (H1) in a measuring volume of a nuclear magnetic resonance permograph (10), surrounded by a high-frequency coil (13) and occupied by an object (12) to be measured. The high-frequency coil (13) is first fed with a high-frequency current of predetermined current intensity. A second high-frequency field strength (Hp) occurring as a consequence is then measured by means of a measuring coil (17, 17') at at least one position outside the measuring volume. From the predetermined current intensity, the measured second field strength (Hp), a predetermined first proportionality between the first (H1) and the second (Hp) field strength, a second proportionality between the current (I) flowing through the high-frequency coil (13) and the first field strength (H1) is furthermore determined. Finally, the second proportionality is used for generating a required calibrated first field strength in the high-frequency coil (13) by setting a measurement current in the high-frequency coil (13).

Abstract: A γ-ray telescope that comprises a dislocation-free single crystal. Typical crystals include silicon and germanium, for example. The crystal is surrounded by an active shield that functions as an anticoincidence counter and a γ-ray detector is disposed adjacent the crystal in order to detect received γ-rays. The y-ray detector comprises an imaging proportional counter, scintillation counter, or a y-ray detecting charge coupled device, for example. The γ-ray detector is based on the Borrmann effect, which is the anomalous transmission of γ-rays through dislocation free single crystals at the Bragg angle. For extended sources, data processing is provided to separate the directional and wavelength dependence of the intensity variation. The y-ray telescope has angular resolution of at least one arc second and may have an effective aperture of several square meters. Reduction in background radiation, which is essentially determined by the crystal thickness, may be made quite large, greater than 10 12.  Consequently, the use of the present invention makes it possible to detect a weak y-ray source even in the presence of a large isotropic background.

Abstract: A system for supporting a dielectric resonator (12) in a circular waveguide (10). A dielectric resonator is held in its optimum position using support posts or rods (11). The support rods are made from a suitable dielectric material, and slip fitted in holes (14) provided at 90° intervals around the periphery of the dielectric resonator. The support rods are affixed to the waveguide, by gluing or being screwed in place. The support rods are slip fitted such that they are allowed to expand, due to temperature, without causing stress on the dielectric resonator, thus the dielectric resonator is held in position without being affixed to its supporting structure. This is an inexpensive and simple solution to a complex problem. The support system is self-centering and free from all stress. The support system utilizes a minimum amount of supporting material which permits realization of the best unloaded Q.
