Abstract: In a multi-sensor system and method of monitoring vital body signals during movement of a body of a human or an animal, acceleration sensors are placed at body locations in such a way that an acceleration angle change induced by the vital body signals differs between the at least two acceleration sensors. The retrieval of the vital body signals is achieved by extracting a wanted vital body signal based on measurement results from multiple sensors that may be motion contaminated. Three retrieval schemes are proposed, each with preferred sensor locations that provide optimal performance of retrieving the vital body signal(s).

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: The present invention provides a method and apparatus for robust tracking at narrow track-pitches on optical discs, enabling higher densities on Blu-ray Discs (5) as well as near-field discs. Increasing radial density results in loss of radial diffraction within the numerical aperture of the lens. Due to this loss in diffraction, current tracking methods, such as Push-Pull and Differential Phase Detection (DPD), will stop working. The invention provides a method and apparatus that relies on cross-correlating the central aperture (CA) signals of 3 optical spots (22, 24, 26) that are positioned such that there are a central spot (24) and spots (22, 26) positioned to the left (22) and right (26) of the central spot (4). By using CA signals, the tangential diffraction is used, which is hardly affected by a track-pitch reduction.

Abstract: A method of fabricating micro crystal fiber lasers and frequency-doubling crystal fibers is disclosed. The micro crystal fiber laser contains gain crystal fibers, frequency-doubling crystal fibers, and a semiconductor laser. The semiconductor laser provides a laser beam. The gain crystal fibers receive the laser beam and generate a base-frequency beam. The frequency-doubling crystal fibers have a polarization alternating period. The frequency-doubling crystal fibers are coupled to the gain crystal fibers to double the frequency of the base-frequency beam and provide a double-frequency beam with the required wavelength. In addition to providing a monochromic crystal fiber laser, the crystal fiber lasers in red, green, and blue light may be combined into an array, providing a color laser. The frequency-doubling crystal fiber can be formed using the LHPG method. During the production process, a polarization alternating external field is continuously imposed on the frequency-doubling crystal fiber, resulting in a polarization alternating period.

Abstract: A radial tracking method for an optical information carrier format with non-uniformly spaced tracks is disclosed, wherein a plurality of tracks (21, 22, 23) are spaced apart at a track pitch TP2, respectively, within a broad spiral (20) having a track pitch TP, in an information layer of an optical information carrier. One central high intensity spot (25) and a plurality of symmetrically placed satellite spots (26, 27) are used for generating a tracking signal for said broad spiral (20). According to an embodiment, the push-pull signal is used for this purpose, resulting in a robust tracking signal. Further, unique address information is retrieved from each of the individual tracks within this broad spiral from a wobble of said tracks. As a result, higher storage densities are achieved, as the method enables tracking of narrowly spaced sub-tracks in a broad spiral that was previously not possible.
