Patent EP-0310207-A2 (EP)
Inventor: JOHNSON BRIAN DR DYNAMICS DIVI
IPC: H04J3/10
Filed: 1985-07-05
Abstract: Analog-to-digital converters are subject to various error inducing factors such as offset errors, scale factor instability, quantisation errors, bit weighing errors, and particularly where samples from two or more multiplexed input signal channels are to be digitized, cross-talk errors in the form of signal residues from one channel which affect subsequent channels. The analog-to-digital conversion apparatus described herein comprises a multiplexer for sampling a series of input channels in a sequence which repeats several times over a predetermined digital value update interval, an analog-to-digital converter which digitizes the samples, and an adder/­memory combination for summing the samples of each signal during the update interval. Offset errors are reduced by an auto-zeroing technique in which half the samples taken in each update interval are inverted prior to digitization and re-inverted after digitization. Preferably, to reduce cross-talk, the auto-zeroing does not just comprise inverting and re-inverting for one complete half of the update interval - rather the auto-zeroing 'on' signal comprises a chosen binary sequence with one bit for each sample. The auto-zero 'on' periods still sum to half the update interval but are distributed over that interval, in effect, so as to decorrelate the channels. By making the update interval equal to the period of some dominant noise component which may appear in the input channels, i.e. the gyro wheel noise in the case of an inertial navigation system, this noise component can be averaged out by the auto=zeroing and sample summation.

Abstract: A comb filter for improved cross-color reduction with improved visible diagonal resolution is provided for processing a luminance component of a quadrature modulated color subcarrier television signal in the vicinity of the color subcarrier pass band. The comb filter comprises an input and an output, and has a first path including a delay circuit for delaying the luminance component and a subtraction circuit connected between the input and the output, and has a second path including a chrominance type comb filter, a band pass filter for passing a spectrum in the vicinity of the color subcarrier pass band both being followed by a variable threshold circuit connected to the subtraction circuit. The variable threshold circuit is for inhibiting the signal in the second path below a variable threshold. The variable threshold is derived as a function of at least one of luminance diagonal transition level, chroma level and averaged luminance activity in the spectrum in the vicinity of the color subcarrier.

Abstract: Method and apparatus for high-speed reproduction of a customized group of audio programs on a slave medium enables the reproduction of musical recordings at a point-of-sale terminal. Master programs are prerecorded by a Dolby ADM (adaptive delta modulated) technique to condense their "information" content and permit higher data throughput during high-speed reproduction. In a "premastering" process to make encoded masters, a special multiplexer board provides interfacing between Dolby ADM digital audio data and a conventional data processing system. The multiplexer board performs computer-like data blocking and also writes a unique sync code directly in the data block. The data processing system also catalogs and edits the blocked digital audio; places encrypted catalog, pricing, and other indicia in the data file representing the music; and sends the data file to a conventional 16-bit PCM file writer for making encoded CD music ROMS which contain the ADM data representing the encoded audio program. A high-speed reproduction device, under control of a desk top personal computer, extracts timing and ADM data from the CD music ROM at high speed and controls high-speed tape drives to compile selected recordings on a single cassette tape in a form compatible with Dolby B noise reduction.

Abstract: Disclosed is a method for the production of homogentisic acid which involves growing a fungus (typically a yeast of the species  Yarrowia lipolytica ) which has been mutated to provide a strain which is unable to grow on L-tyrosine and/or L-phenylalanine as the sole carbon source in a suitable growth medium containing L-tyrosine and/or L-phenylalanine together with a sub-optimal concentration of carbohydrate assimilable by the yeast. The yeast secretes recoverable quantities of homogentisic acid which can be rapidly and completely polymerized by raising the pH of the medium to above 10 thereby forming a melanin pigment.

Abstract: In pressure-operated switchgear, in particular for household appliances such as water heaters, which contain in a plastic housing a pressure-operated actuating member for an actuation part of an electrical switch element arranged in the housing, which switch element is loaded by an adjusting spring supported in the housing on a support, the unavoidable temperature changes to which the pressure-operated switchgear is subject lead to form changes of the housing, resulting in a misalignment of the switching point of the switch element. According to the invention, at least the support (W) of the adjusting spring (22) is arranged on a carrier (T) which is made of a material that is form-stable under the influence of temperature at least in the deflection direction of the actuating member (19) and is mounted in the housing (2) at points (35) which remain essentially deformation-free under the influence of temperature in the deflection direction of the actuating member. <IMAGE>

Abstract: For reasons of safety, such energy-rich gaseous fuels are in general made available in known gas supplies only at low pressures, as a result of which there is a limit to the possibilities of use for these gaseous fuels. In order to overcome this disadvantage, without having to equip entire supply installations with safety technology, it is proposed to increase the pressure of the acetylene or gaseous fuel to a desired value which is higher than otherwise available from the supply with a corresponding device only as required and directly before the respective consumer(s).

Abstract: An inlet port of a manual timing valve (306) is pressurized from a source of regulated line pressure through a manual valve when the vehicle operator selects certain gears manually. Hydraulic flow through this port enters the manual timing valve through an orifice (364) sized to control the flow rate. A first volume of the timing valve increases in size as a first piston (360) moves due to pressure of fluid flowing to the valve through the orifice. Pressure within the first volume is maintained constant while the first volume expands during a first interval, which ends when the first piston reaches the extremity of its motion. Thereafter, pressure entering the valve through the orifice increases abruptly and causes a second piston (330) to move against the force of a spring due to the increased pressure force developed on the second piston after the first volume stops expanding. As the second piston moves the size of a second volume increases during a second interval until the second piston bottoms. When this occurs, the valve opens a connection between the first port (360) and an outlet port (334) through a bypass line in which there is no restriction.
