Filed: 1991-03-22
Abstract: A method for electrically attenuating a noise in an area for a sound wave to be propagatable in a three dimensional direction by making up a drive signal from the information on the noise and previously given filter coefficients by use of an adaptive digital filter and then generating an additional sound wave in accordance with the drive signal for cancellation of the noise. In the electric noise attenuation method, there are provided ,in a given region for noise attenuation, first and second error sensor groups for detecting an interference sound wave produced between the noise and additional sound wave, at a sampling time, a filter coefficient is calculated based on the information relating to the first error sensor group, at the next sampling time, another filter coefficient is calculated based on the information relating to the second error sensor group, and these operations are repeatedly executed sequentially for each error sensor to thereby update the filter coefficient of the adaptive digital filter.

Abstract: A non-contact method for monitoring the tension in an optical waveguide fiber during drawing is provided. The motion of the fiber is sensed in a direction transverse to the direction in which the fiber is moving. The sensed motion is analyzed to determine a plurality of frequency components thereof, each frequency component having a magnitude, and one of the components constituting the maximum magnitude component. The frequency of the maximum magnitude component is doubled to obtain a doubled frequency. The presence of a frequency component near the doubled frequency is ascertained to verify that the maximum magnitude component is the principal harmonic frequency of motion of the fiber. The tension in the fiber is then determined from the verified principal harmonic frequency component.

Abstract: This invention relates to methods and apparatus for marking letter mail or mail pieces to provide a fast and convenient way of determining zip code breaks in a stack of letter mail. The mail pieces have marks printed on the edges thereof indicative of the continuity of the same zip codes thereon. The marks are visible when the mail pieces are stacked. Adjacent envelopes with the same zip codes will have an edge mark at the same location, but upon the zip code changing, the next envelope will have a mark placed at a different location. 
     Numbers in sequence can be printed on each of the letters so that a mail clerk can inspect the last letter within a zip code group to determine if there is a sufficient number of mail pieces within that zip code set to allow a postal discount. 
     In an alternative embodiment, the markings on the side of the mail pieces are printed in a pattern so as to form numbers when a stack is viewed from the side. In addition to forming numbers, a pattern line can extend between the numbers. This allows a postal clerk to look at a stack of envelopes in a tray and from the side markings not only determine which of these envelopes are in the same zip code set, but also there would be an indication of the last number of the zip code.

Abstract: A three-dimensional graphic display system having an increased speed hidden-surface process capability. At a time when a depth buffer memory would be initialized in a conventional three-dimensional graphic display system, the depth buffer memory itself is not initialized and only bits of a high-speed memory corresponding to bits to be initialized in the depth buffer memory are initialized. When a hidden-surface process is executed, if the bits of the high-speed memory have been initialized, those initialization bits are changed to a non-initialized state and the latest Z coordinate data from a line generator is unconditionally written in the depth buffer memory. When the initialization bits of the high-speed memory are in a non-initialized state, a comparator compares Z coordinate data supplied from the depth buffer memory with the latest Z coordinate data supplied from the line generator. On the basis of the results of such comparison, a hidden-surface process is executed to display a three-dimensional graphic image.

Abstract: In a method for operating a sewage treatment plant, the electrolytic conductivity of the feed effluent (waste water) and the flow rate thereof are continuously measured and used to form a parameter (S) determining the rate of a precipitant to be added. Individual measurements of the phosphate concentration are carried out in this case. The load signal is corrected in dependence on these individual measurements. An apparatus for injecting the phosphate precipitant has a precipitant pump (12) and an actuating apparatus (14) determining the throughput. In addition, there is a conductivity metering apparatus (19) in the feed effluent, a flow meter (16) and a control apparatus (18) which continuously calculates a parameter (S) for the actuating apparatus (14) from conductivity (LF), flow rate (Q) and, if necessary, correction values. In this manner, on-line operation is possible with precipitant metering operating almost precisely. <IMAGE>

Abstract: An electrophoresis apparatus (30) for automatically performing medical assays includes an electrophoresis platform (48) which cooperates with a gantry assembly (56). The electrophoresis platform and the gantry assembly are movable along paths that are perpendicular to each other. An applicator assembly (50) includes pipettes (52) which transfer fluid samples from a specimen tray (158) to an electrophoresis plate (110) mounted on the electrophoresis platform. The electrophoresis platform then moves to a position into the gantry assembly, where electrophoresis is conducted to separate the samples into different fractions. The electrophoresis platform then moves beneath a reagent pouring station (54) where a reagent is applied to make the separated fractions fluoresce under ultraviolet light. The electrophoresis platform is then moved beneath the gantry assembly again, and an air knife (338) in the gantry assembly spreads the reagent. After incubation and drying of the electrophoresis plate, the electrophoresis platform and gantry assembly are moved relative to one another while the electrophoresis plate is read with the aid of ultraviolet lamps (296) and a photomultiplier tube (312) mounted in the gantry assembly. The gain of the photomultiplier tube is automatically adjusted and the data gathered is automatically edited to remove background noise. The edited results can be printed or displayed on a video monitor.
