Image stabilizer for a microcamera module of a handheld device, and method for stabilizing a microcamera module of a handheld device
InactiveUS7307653B2Compensation effectTelevision system detailsPrintersComputer moduleDisplay device
A method and a handheld device for stabilizing an image captured by an optical lens of a micro camera integral with the handheld device, which may, for example, be a mobile phone. Motion sensors sense motion of the device and are used to cause movement of the micro camera to substantially compensate for the sensed movement so as to maintain a steady, focussed image to be displayed by a display on the handheld device or elsewhere, such as a remote display. The micro camera is moved by one or more motion actuators which move the camera in a horizontal plane substantially perpendicular to an axis of the lens of the camera and / or move the camera so as to pivot the lens axis.

Method and apparatus for spectrum analysis and encoder
InactiveUS6897952B1Increase motor speedReduce motor speedRadiation pyrometrySpectrum generation using diffraction elementsModulation functionFrequency spectrum
A disc serving as a spatial radiation modulator has dispersed radiation filters thereon. Each filter has a transmittance or reflectance modulation function of the form sin2(mθ+pπ / 4), where m is a positive integer and p has one of the four values 0, 1, 2, 3. A radiation beam including selected wavelength components is diffracted into an elongated image dispersed according to wavelength. Different wavelength components are focused onto different filters on the modulator and are encoded by corresponding filters. Since the modulation functions of the filters are orthogonal to one another, it is possible to extract the amplitude of each wavelength component after it has been encoded or modulated by corresponding filter from the total detected signal during one measurement.

High pass modulation of a phase locked loop
ActiveUS20070036238A1Drawback and limitationCompensation effectModulated-carrier systemsAngle modulationDigital signal processingRadio frequency
A radio frequency modulator based on direct frequency / phase modulation of output signal of a controllable oscillator (724) that is a part of a phase locked loop (PLL) provides a direct modulator that is able to operate over a wide frequency range with a flat frequency response. A modulation signal is digitally processed (721, 730) before injection to a high-pass path of a direct modulator. Applicability of digital signal processing is based on the fact that the modulation signal is a base band signal. Therefore, the modulation signal (702) occupies such a band in the frequency domain so that a sufficient ratio of a sampling rate to an upper edge frequency of the modulation signal can be achieved. Digital processing is used for compensating an effect of non-flat high-pass PLL transfer function and / or to perform pre-distortion of the input signal of a controlled oscillator to compensate an effect of non-linearity of a controlled oscillator.

Signal-to-noise ratio estimation of CDMA signals
ActiveUS7313167B2Cancel improvementMinimize timePower managementEnergy efficient ICTSignal-to-noise ratio (imaging)Deterministic noise
An improved approach to noise estimation permits, for example, tighter closed-loop power control in a wireless communication network with attendant improvements in transmit power efficiency and network capacity. In an exemplary embodiment, the received signal-to-noise ratio (SNR) of a data signal is estimated based on noise samples obtained from one or more other signals received in association with the data signal. In general, these associated signals are characterized by the receiver's ability to extract like valued samples from them, such that pairs of these like valued signal samples may be subtracted, thereby canceling their deterministic signal components and leaving only difference values representative of the non-deterministic noise components of the signal samples. Obtaining difference values from more than one associated signal increases the sample size of difference values used in noise estimation, thereby improving the statistical basis for noise estimation and, therefore, the accuracy of SNR estimation.
