20130033389 | DATA VALUE OCCURRENCE INFORMATION FOR DATA COMPRESSION - A method for generating occurrence data of data values for enabling encoding of a data set includes determining occurrences of data values in a first data batch and determining occurrence count information for a first number of most frequent data values in the first data batch, the occurrence count information identifying the most frequent data values and their occurrence counts. The method also includes generating for rest of the data values in the first data batch at least a first histogram having a second number of buckets and merging the occurrence count information of the first data batch with occurrence count information of a second data batch. The method further includes merging the first histogram of the first data batch to a merged histogram corresponding to the second data batch and processing a next data batch as a first data batch until the data set to be encoded is processed. | 2013-02-07 |
20130033390 | ANALOG INPUT SYSTEM, ANALOG OUTPUT SYSTEM, AND ANALOG INPUT/OUTPUT SYSTEM - To increase the number of analog inputs at low cost, an analog input system includes: one or more analog slave units each connected to a bus to which a CPU unit is connected, and each including an A/D-conversion device converting an analog value outputted by an external device into a first digital value, a buffer memory buffering a second digital value to be transferred to the CPU unit, and a nonvolatile storage device containing specific information of its own unit; and an analog master unit connected to the bus and including an operation section performing operation processing based on the specific information stored in the storage device with the first digital value being used as an input, to calculate the second digital value, the master unit performing on each of the slave input units the operation processing and processing of transferring the calculated second digital value to the buffer memory. | 2013-02-07 |
20130033391 | MULTIPLYING DIGITAL-TO-ANALOG CONVERTERS AND PIPELINE ANALOG-TO-DIGITAL CONVERTER USING THE SAME - A multiplying digital-to-analog converter (MDAC) is provided. The MDAC includes a sub DAC decoding circuit, a capacitor-switch circuit, and an operation amplifier circuit. The capacitor-switch circuit includes at least two sampling capacitor sets which are coupled in parallel. The number of sampling capacitors in one of the sampling capacitor sets is larger than or equal to two. Each sampling capacitor set is coupled to an analog-signal input quantity through a sampling switch and to a corresponding output terminal of the sub DAC decoding circuit through a decoding switch. The sub DAC decoding circuit decodes a digital quantity and outputs a corresponding analog signal at each output terminal, such that the corresponding analog signals are applied to the respective sampling capacitor sets through the decoding switches and summed by the respective sampling capacitor sets to obtain an analog-signal quantity corresponding to the digital quantity. | 2013-02-07 |
20130033392 | SUCCESSIVE APPROXIMATION REGISTER ADC CIRCUITS AND METHODS - A non-binary successive approximation analogue to digital converter, for converting using successive conversion steps, is operable in first and second modes. The first and second modes have different noise properties and the converter is switched between the modes during the conversion process. | 2013-02-07 |
20130033393 | System and Method for Suppressing Interference in Frequency-Modulated Radar Systems - The invention relates to a system having an emitter for emitting a first microwave radiation, a receiver for detecting a second microwave radiation derived from the first microwave radiation and a control system connected to the emitter and the receiver. The first microwave radiation is emitted at a plurality of points in time at different frequencies assigned to the points in time. The correlation of point in time and frequency is random or pseudo-random. Alternatively or additionally, at the point in time, the length of the time period for an emission or reception is random or pseudo-random. The invention further relates to a method for suppressing interference in frequency-modulated radar systems. | 2013-02-07 |
