Title: Method for checking tablespaces involved in referential integrity
Inventor: WEAVER STEPHEN J
IPC: G06F17/30
Filed: 1999-10-27
Granted: 2005-02-01
Abstract: A recover or reload utility determines if a check utility is to be executed. If a check utility is to be executed, the recover or reload records the dependent tablespace names to virtual storage allocated to a job step (1040) instead of to virtual storage allocated to a subtask (1050). After the recover or reload performs its function, if a check utility is next, the database operating system will not freemain the virtual storage (e.g., data area) into which the recover or reload utility has recorded the names of the dependent tables when the subtask ends. Upon termination of the recover or reload utility, the persistent data area is available for the check utility to use.

Abstract: A postage meter (franking machine) uses a digital print head such as an ink jet or thermal transfer or dot-matrix print head, for which it is necessary to know the velocity of the mail piece passing by the print head. Two collimated monochromatic beams strike the mail piece, one at an angle leading the mail piece velocity and the other at an angle lagging the mail piece velocity. The beams converge yielding a sensing region filled with a diffraction pattern. The mail piece, assumed to be rough at a scale that is appropriate for the velocity measurement, moves at some velocity. A detector detects light intensity (photon flux) at a small region within the sensing region, and the intensity signal has a frequency that is proportional to the mail piece velocity. The frequency is detected or measured, the instantaneous velocity is derived therefrom, and the velocity is used to control the print head: In this way a two-dimensional print image (postage indicium) is faithfully printed on the mail piece with minimal distortion even in the event of non- constant velocity of the mail piece.

Abstract: A method and apparatus for multi-level color error diffusion employs semi- vector quantization. When operating on image data comprising three color separations, the method employs a vector quantization for the two separations with the most visually perceptive color output to generate a multi-level output pixel for each separation based on the sum and a difference of the input pixel values for the two separations. The method generates multilevel output pixels for the third color separation using scalar error diffusion.

Abstract: The invention consists of a pop-in extended travel single roller for patio doors. This roller assembly is retained in the patio door track by no mechanical means. This is accomplished by mounting the roller assembly into a pre-fabricated opening, the width of which is slightly larger than the over-all basic width of the outer housing. Protrusions on the side of the outer housing, after passing through the opening, retain the roller in the proper position. This feature eliminates the need for mechanical fasteners thereby saving costs of parts and labor. This assembly also provides for increased over-all height adjustment range. Finally, this invention through the use of an adjusting screw aids the ease of removal of the movable panel of the patio door assembly.

IPC: H04B7/185
Filed: 2001-12-19
Granted: 2005-06-21
Abstract: A method and apparatus for providing remote control of the output power level of an amplifier. The method uses pulse width or pulse density modulated signal proportional to the power level of the amplifier. This signal is detected and filtered to provide a control voltage to the apparatus mentioned below. The apparatus includes an amplifier, and a comparator having a first input coupled to an output terminal of the amplifier, a second input coupled to a control signal, and an output terminal coupled to an input terminal of the amplifier. The amplifier and comparator operate to form a feedback loop which functions to equalize the voltage level of an output signal present at the output terminal of the amplifier to the voltage level of the control signal. The equalization of the voltage level of the output signal of the amplifier to the voltage level of the control signal is effected by adjusting the drain current flowing through the amplifier. Accordingly, by varying the voltage level of the control signal, the power level of the output signal of the amplifier can be varied.
