Publication number: 20070008156Abstract: An object of the invention is to provide a bed which can surely detect the positional shift and heartbeat vibration of a bedded person while suppressing the increase of the cost and the degradation of the comfortability of a bed, and to provide a bed and an in-bed state detection method which can prevent the undesirable caught at the time of elevating the bed. In order to detect the shift of a bedded person, a ratio of intensities between output signals from first pressure sensitive sensor 21 and a second pressure sensitive sensor 22 each having a cable shape is obtained. These sensors are disposed along the lying direction at the both end sides of a bedding surface 15a on which a bedded person lies, respectively. When the ratio is in a range of a predetermined shift state set in advance, it is determined that the positional shift of a bedded person on the bedding surface 15a occurs. Further, a low-repulsion urethane layer is provided within a bed pad thereby to detect the heartbeat vibration.Type: ApplicationFiled: June 18, 2004Publication date: January 11, 2007Applicant: Matsushita Electric Industrial Co., Ltd.Inventors: Shigeki Ueda, Hiroyuki Ogino

Publication number: 20070008195Abstract: A received signal is sampled at a sampling period of T+m*(T/n) during a sampling phase determination process. T is a symbol or chip period of the received signal, n is a number of phases of the sampled signal, T/n is a phase resolution period, and m is a fixed non-zero integer value where ?n<m<n (e.g. m=1 or ?1). By sampling the received signal at the sampling period of T+m*(T/n), a sample set for each one of n phases of the sampled signal is produced. For each sample set, a correlation process is performed between the sample set and a predetermined correlation signal to produce a correlation result. Once an optimal correlation result is identified from the correlation process, the received signal is sampled at a sampling period of T at a phase associated with the optimal correlation result. Advantageously, oversampling at a sampling rate of n/T is not required during the sampling phase determination process, which reduces cost and power consumption.Type: ApplicationFiled: July 8, 2005Publication date: January 11, 2007Inventor: Xin Jin

The inverters associated with the negative outputs in the sigma-delta modulator are removed and the clock signal used to drive the transistors corresponding to the negative outputs is negated or shifted 180 degrees from the clock used to drive the transistors corresponding to the positive outputs. A non-inverted version of the clock is used with the positive outputs and an inverse clock is used with the negative outputs. Use of the inverse clock causes a negative contributive offset to be generated that is added on the second half cycle of each clock. The result is an offset compensated RF output signal having zero offset.Type: ApplicationFiled: July 11, 2005Publication date: January 11, 2007Inventors: Sameh Rezeq, Dirk Leipold, Robert Staszewski, Chih-Ming Hung

Publication number: 20070008200Abstract: A primary delta-sigma modulator converts a continuous-time input signal into a discrete-time output sequence. A calibration circuit comprising an auxiliary delta-sigma modulator estimates percentage error in an integrator time constant and adjusts the time constant of at least one integrator in the primary delta-sigma modulator accordingly. The auxiliary delta-sigma modulator and the primary delta-sigma modulator use integrators with substantially similar circuit designs. The percentage error in the time constant of the integrator in the auxiliary delta-sigma modulator, and correspondingly the percentage error in time constant of the integrator in the primary delta-sigma modulator, is estimated by injecting a calibrating sequence into the auxiliary delta-sigma modulator and examining a correlation between an error sequence and an output sequence of the auxiliary delta-sigma modulator.Type: ApplicationFiled: March 27, 2006Publication date: January 11, 2007Inventors: Hong-Yean Hsieh, Chia-Liang Lin

Publication number: 20070008201Abstract: A bubble error rejecter includes a cascade of front and rear voting sections for correcting bubble errors spanning multiple bits from interpolation. The front voting section generates first correction codes from first thermometer codes determined from preamplified signals. The rear voting section generates second correction codes from the first correction codes and second thermometer codes determined from interpolation of the preamplified signals.Type: ApplicationFiled: June 13, 2006Publication date: January 11, 2007Inventors: Ho-Young Lee, Yong-Sang You, Hong-June Park, Jun-Hyun Bae, Young-Chan Jang

Publication number: 20070008202Abstract: A sigma-delta converter has a signal input for receiving a data word. A clock signal input is designed to supply a clock signal. The sigma-delta converter includes a first clocked-operation accumulator stage whose input side is connected to the signal input, and at least one second clocked-operation accumulator stage connected in series with the first accumulator stage, with its input side coupled to an accumulator output of the first accumulator stage. The sigma-delta converter is configured to process the data word upon each clock signal only in one accumulator stage in the first and the at least one second accumulator stage, and output the processed data word at the accumulator output of the one accumulator stage. As a result, a time-critical response during signal processing is limited just to the accumulator stage which is currently processing the data word.Type: ApplicationFiled: June 23, 2006Publication date: January 11, 2007Inventor: Giuseppe Puma

Publication number: 20070008203Abstract: In the two-stage conversion type of digital-to-analog converter, the m most significant bits in a digital signal are provided to a first-stage selector, selecting a pair of adjacent lower and upper limit voltages among 2m+1 different stepwise voltages generated by a resistive voltage divider. The resistors divide the voltage between the lower and upper limits into different divided voltages. A second-stage selector selects corresponding one of the divided voltages according to two least significant bits in the digital signal. When the digital signal changes, a load signal is provided for a predetermined time period, allowing switches to short-circuit respective component resistors. The output of the second-stage selector is thus quickly charged to the upper limit voltage when the digital signal changes. When the load signal subsequently stops, the normal divided voltage is generated, providing the target output voltage. Thus, the conversion accuracy and response speed are improved.Type: ApplicationFiled: June 28, 2006Publication date: January 11, 2007Applicant: Oki Electric Industry Co., Ltd.Inventor: Atsushi Hirama

Publication number: 20070008204Abstract: Disclosed is a bit-detection arrangement able to convert an analog signal (AS) having an amplitude into a digital signal (DS) representing a bit sequence from which the analog signal (AS) is derived. The bit-detection arrangement has a phase detector which detect the phase difference between a quantized analog signal and a clock signal C2. The phase difference is sampled by an AD converter. The AD converter can sample at a relatively slow rate as the phase difference is a low frequency signal. The sampled phase difference is fed to a digital PLL which outputs a phase signal PHI. The phase signal and the quantized analog signal are used to recreate the digital signal (DS).Type: ApplicationFiled: May 25, 2004Publication date: January 11, 2007Applicant: Koninklijke Philips Electronics N.V.Inventors: Albertus Johannes Antonius Rutten, Nicolaas Maria Van Beurden, Josephus Maria Kahlman, Albert Immink

Publication number: 20070008205Abstract: Pulses of optical radiation are counted by a pulse counter in a way representative of its effects on tissue. An analog to digital converter digitizes detected optical radiation pulses and an integrator integrates the digitally detected pluses. The integrator has a time constant characteristic sufficient to combine digitally detected pluses that are close enough together so that they are effectively one pulse with respect to tissue exposure limits. The integrator can be programmable to a particular time constant based on a thermal confinement duration of human tissue and wavelength of laser pulses. A counter circuit counts pulses, and a display displays the counted pulses. A capture circuit enables counting the number of pulses occurring within a capture duration by the counter circuit. The analog to digital converter can be configured to a sensitivity.Type: ApplicationFiled: July 6, 2005Publication date: January 11, 2007Inventors: Robert Aldrich, Wesley Marshall
