    摘要: The invention relates to a system and a method in which an electrophysiological signal is sensed capacitively with at least two closely spaced electrodes such that the electrodes experience strongly correlated skin-electrode distance variations. To be able to derive a motion artifact signal, the capacitive coupling between the electrodes and skin is made intentionally different. With a signal processing means the motion artifact signal can be removed from the measured signal to leave only the desired electrophysiological signal. Since the measured quantity is dependant on the electrode-skin distance itself, the system and method do not need to rely on the constancy of a transfer function. Hereby, they give reliable motion artifact free output signals.

    摘要: A wobble signal is generated from at least two elementary signals (A,B,C,D) detected by scanning a wobbled track of a data carrier. The invention proposes a solution for eliminating the noise of various origins in the wobble signal, notably the high frequency data leakage into the wobble signal due to radial asymmetry introduced in the diffraction pattern on the detector, whatever the reason for this radial asymmetry. According to the invention, the at least two elementary signals are filtered with at least an adaptive filter (40), and said filtered elementary signals are subtracted (44) from said wobble signal (PP) thereby generating an improved wobble signal.

    摘要: A liquid reservoir used in a heat exchanger, for example an automotive air conditioner, and a manufacturing method therefor. The liquid reservoir includes an inlet hole and an outlet hole. The outlet hole is provided with a filter element covering the outlet hole. A flow area at a location of the outlet hole covered by the filter element is greater than the cross-sectional area of other locations of the outlet hole. In this way, in the case that other structures of the inlet hole are not improved, a filtering area of the filter element is increased, thereby increasing a flow area of a refrigerant, reducing a flow resistance effect exerted by the filter element on the refrigerant, and reducing a workload of the heat exchanger.

    摘要: This invention relates to an activity monitoring system adapted to eliminate passive movement components caused by external forces from readout data produced by a first and a second motion sensor when attached to a subject during movement. The readout data include gravitational components, movement components caused by active movement of the subject or subject parts, and the passive movement components. A processor estimates first and second gravitational components produced by the at least first and a second motion sensors. It determines a rotation matrix based on the estimated gravitational components, the rotation matrix denoting rotation required for the first sensor to get aligned with the second sensor in orientation. It then multiplies the readout data produced by the first motion sensor with the rotation matrix when rotating the first sensor towards the second sensor. Finally, it subtracts the result of the multiplying from the readout data produced by the second motion sensor when rotating the first motion sensor towards the second motion sensor.

    摘要: The invention discloses an optical recording drive for recording data on an optical carrier such as an optical disk of the DVD or BD format. A radiation source is arranged to emit a write pulse train (80) for writing an optically detectable effect (90) i.e. a pit or mark. Photo detection means (10) detects a first reflected radiation beam pulse (R1) from a start time portion of the write pulse train (80) and generates a corresponding first signal (PS1) indicative of the power in the first pulse, the photo detection means (10) further detects a second reflected radiation pulse (R2) from an end time portion of the write pulse train (80) and generates a corresponding second signal (PS2) indicative of the power in the second pulse. By comparing (e.g. the heights of) the first signal (PS1) and the second signal (PS2), it is possible to get an indication of the received power in the optically detectable effect (90) as delivered by a power level (81; 82) in the write pulse train (80) continuously during writing and for a broad range of carrier rotation speeds.

    摘要: A tracking error (TE) signal is formed from a single spot on a photodetector 25 to improve the robustness in optical disc applications having a reduced track-pitch. Reduced track pitches are employed in high data capacity optical disc formats. By using high frequency cross-correlation of a central aperture signal, the differences within the left 21 and right 23 detector halves yield a divergence from the zero crossing that produces a more pronounced tracking signal. The more pronounced tracking signal is insensitive to incoherent cross talk in multi-layer discs.

    摘要: The invention relates to an electronic device for estimating energy consumption of a person. The electronic device uses a mathematical model based on acceleration data for estimating the person's energy consumption as a function of the actual performed activity and acceleration values. The acceleration values are converted to an estimate of energy consumption of a given activity by scaling a value of time integrated acceleration data with an activity scaling parameter. The activity scaling parameters for different activities have been determined off-line by comparing measured energy consumptions over e.g. a day with estimated energy consumptions over the same period, where the estimated values are determined using the mathematical model.
