    摘要: A photoelectric type pulse signal measuring method includes, obtaining a main-path light signal transmitted by a photoelectric transmitter and reflected back from a surface of skin having an artery underneath, obtaining at least one auxiliary-path light signal receiving an ambient light signal, and based on the at least one auxiliary-path light signal, adaptively filtering an ambient light interference from the main-path light signal and obtaining an adaptive filtration result; or obtaining at least one auxiliary-path light signal transmitted by the same photoelectric transmitter and reflected back from a surface of skin without any artery underneath, and based on the auxiliary-path light signal, adaptively filtering a motion interference from the main-path light signal; then extracting a pulse signal from the adaptive filtration result. The present invention can simply and effectively eliminate the ambient light interference or motion interference upon photoelectric pulse signal measurement. Photoelectric type pulse signal measuring devices are also disclosed.

    摘要: A wearing state detection method for a wearable device and a device. The detection method comprises: providing in the wearable device a sensor in an area capable of contacting the skin of a user, wherein the sensor outputs different measurement values when the user wears or takes off the wearable device; acquiring a base value indicating whether the wearable device is being worn; after wearing detection has been started up, collecting measurement values from the sensor at a preset sampling frequency; judging whether the wearable device is currently in a wearing state according to the measurement values and the base value; and controlling the wearable device to turn off a corresponding function that is running when the wearable device is in a non-wearing state. The method and the device can reduce the power consumption and simplify user operation.

    摘要: A tactile vibration control system and method for a smart terminal. The system includes: a command generator, a tactile driver, a linear resonant actuator, a sensing module, a feedback unit and a comparator; by arranging a plurality of sensors that monitor or sense the vibrating status of the linear resonant actuator, channels of the sensor signals are generated when the actuator vibrates; the feedback unit sends the sensing signals characterizing the physical quantities related to the vibration modes output by the plurality of sensors to the comparator as the feedback signal; and the comparator generates an error signal according to the feedback signal and a desired signal in the input signal and sends the error signal to the command generator so that the command generator adjusts the generated initial commanding signal according to the error signal and achieves the close-loop control of the linear resonant actuator.

    摘要: A tactile vibration control system and method for a smart terminal. The system includes a command generator, a filter, a tactile driver and a linear resonant actuator; the command generator generates an initial commanding signal according to an input signal; the filter filters the initial commanding signal so that amplitudes of a predetermined number of initial pulses of the filtered commanding signal are larger than a set threshold and phases of a predetermined number of ending pulses reverse; and the tactile driver generates a driving signal according to the filtered commanding signal for driving the actuator to vibrate. The initial commanding signal generated by the command generator is filtered so that when the actuator is driven to vibrate by the driving signal generated subsequently, the actuator has a quick starting response and a quick braking response.

    摘要: The present invention discloses a howling suppression method and device applied to an ANR earphone. The method comprises: collecting signals by using a first microphone and a second microphone; wherein the first microphone is arranged in a position outside an auditory meatus when said ANR earphone is worn, and the second microphone is arranged in a position inside the auditory meatus when the ANR earphone is worn; according to a relation between signals collected by the first microphone and the second microphone, judging whether the current state of said ANR earphone is a state unable to produce a howling or a state able to produce a howling; and when the current state of said ANR earphone is a state able to produce a howling, starting processing for preventing howling production. The technical scheme can achieve that the ANR earphone does not produce a howling all the time.
