摘要： Embodiments are provided for managing the operation of sensors in an electronic device. According to certain aspects, the electronic device may detect a change in motion from a set of lower-sensitivity sensor data generated by a sensor(s) operating in a lower-sensitivity mode. When the change in motion is detected and during a timeout window, the sensor(s) may generate an additional set of lower-sensitivity sensor data and a set of higher-sensitivity sensor data. The electronic device may initially confirm the change in motion based on analyzing the set of higher-sensitivity sensor data. Further, the electronic device may determine that the additional set of lower-sensitivity does not indicate an additional change in motion, and may deem the confirmation of the change in motion as a false positive.

摘要： Methods and devices for detecting movement of an object includes: receiving a plurality of output signal values from a sound wave receiver, each of the plurality of output signal values being representative of a distance between the object and the sound wave receiver; determining, based on the received plurality of output signal values, a difference value representative of a difference between a first output signal value and a second output signal value among the plurality of output signal values; determining whether the difference value is representative of motion of the object based on whether the difference value has a magnitude between a predetermined minimum threshold and a predetermined maximum threshold; and outputting a motion detection signal if the difference value is determined to have a magnitude between the predetermined minimum threshold and the predetermined maximum threshold.

摘要： A method for determining a flow acceleration directly from beamformed ultrasound data includes extracting a sub-set of data from the beamformed ultrasound data, wherein the sub-set of data corresponds to predetermined times and predetermined positions of interest, determining the flow acceleration directly from the extracted sub-set of data, and generating a signal indicative of the determined flow acceleration. An apparatus includes a beamformer (112) configured to processes electrical signals indicative of received echoes produced in response to an interaction of a transmitted ultrasound signal with tissue and generate RF data, and an acceleration flow processor (114) configured to directly process the RF data and generate a flow acceleration therefrom.

摘要： An ultrasound input device can be coupled to a material layer having an external surface located opposite the material layer from the ultrasound input device. The ultrasound input device can transmit an emitted signal through the material layer towards the external surface and receive a set of reflected ultrasound signals associated with the emitted signal. The set of reflected ultrasound signals comprises at least one reflected ultrasound signal, and the set of reflected ultrasound signals can be associated with a touch event between an object and the external surface. A system can comprise one or more data processors configured for performing operations including determining an energy signal associated with the set of reflected ultrasound signals, extracting feature information associated with the energy signal, determining an inference associated with the object based on the extracted feature information, and generating an output signal associated with the determined inference.

摘要： An ultrasonic Doppler diagnostic equipment comprising a spectrum measurement unit which measures a Doppler spectrum, a decision unit which determines processing conditions of an average process on the basis of power values of spectral components in the Doppler spectrum, an average process unit which performs the average process of the Doppler spectrum on the basis of the processing conditions determined by the decision unit, and a display unit which displays a Doppler spectral image on the basis of the Doppler spectrum subjected to the average process by the average process unit. According to the configuration, the ultrasonic Doppler diagnostic equipment can improve discontinuities in those spectral components of small power values which are susceptible to interference noise, in the Doppler spectral image, and it can generate image data of high resolution.

摘要： A method for velocity estimation based on a complex demodulated doppler signal in a multi-gated doppler. The method is based on the autocorrelation function estimates of the complex demodulated doppler signal. Contribution to the correlation function from the receiver noise is found by measuring the noise in absence of echo signals. The obtained values are subtracted from the correlation estimates before further processing. A limited number of candidates for the true velocity are calculated from the autocorrelation function phase.

摘要： A non-intrusive vibration measurement system and method using commercial ultrasonic instruments together with digital signal filtering and analysis techniques is adapted to quantitatively detect vibrations as small as 0.04-inch peak-to-peak. The system and its methodology is used for in-service vibration monitoring of internal components of check valves, pumps, nuclear reactors, steam generators and heat exchangers, especially when the vibration frequency is too low for quantitative analysis by accelerometers and when the strain induced is too low for strain gauge analysis, and when the vibrating component is in an "encased" environment.

摘要： The proposed method permits expansion, compression or reversion of a frequency of a Doppler shift signal. Shift frequency components of a measured Doppler shift signal are multiplied desired times so as to eliminate aliasing or permit precise detection of slow targets. A phase difference obtained at a time in a very short period is substituted with a phase difference obtained in a period longer than the very short period. The frequency conversion is applicable to the continuous wave Doppler system and the pulsed Doppler system.

摘要： Current-responsive light-emitting diodes of different colors are provided adjacent to the tip of the hand-held transducer probe of a medical Doppler device. Mechanism is provided to actuate the diodes of one color when the direction of internal body matter detected by the Doppler device is toward the probe and to actuate lights of a different color when the direction of detected internal body matter is away from the probe. In addition, power supply to the diodes is controlled so that increasing brightness indicates increasing velocity of the detected internal body matter.
