A detection device including n number of sensors arrayed in a direction, in which n is an integer of 3 or more and from which (n1) pairs of adjacent sensors are formed, and a processor which determines one specified position in the direction based on output values of the n number of sensors, in which the processor calculates (n1) sets of difference values each of which is a difference between two output values corresponding to each of the (n1) pairs of sensors, and determines the one specified position based on the (n1) sets of difference values and correlation positions corresponding to the (n1) sets of difference values and indicating positions correlated with array positions of each pair of sensors.

Electronic musical instruments as disclosed, include sensors to digitize and alter the sound using FSR sensors in the mouthpieces and other elements of the instrument to mimic the variations available in analog instruments.

The present invention provides a method and apparatus for controlling a light-emitting device of a digital keyboard musical instrument. The method includes: detecting a touch action generated by a user upon a key of the digital keyboard musical instrument and generating a touch signal, by a sensor placed underneath the key, and transmitting the touch signal to a processor, wherein the touch signal comprises the magnitude information of the touch action; receiving the touch signal and generating a corresponding control signal in accordance with the magnitude information of the touch signal, by the processor; and actuating the light-emitting device to produce a light-emitting effect in accordance with the control signal by the processor. Since the detection of the touch action upon the key by the sensors is accurate enough to capture all details of the complete key-touching action, the light-emitting effect produced based on this more detailed detection of the touch action is more exquisite and accurate.

A wearable sensor system is disclosed that provides a measurable magnetic field that changes horizontally within the range of motion of human limbs. The wearable sensor system includes a magnetic sensing device, and one or more magnet devices that provide the measurable magnetic field with a strength exceeding the Earth's magnetic field. To this end, the magnetic sensing system provides a personal magnetic field about a user, with that magnetic field traveling with the user and overpowering adjacent interfering fields. The wearable sensor system may include a sensor arrangement that measures a strength of the personal magnetic field and field direction to perform horizontal localization, and may send a representation of a same to a remote computing device to cause an action to occur. Some such actions include output of pre-recorded or synthesized musical notes, for example.

The present disclosure relates to a sensor comprising a resonant circuit, a driver, a drive enable circuit, a sample-and-hold-circuit, and a measurement circuit. The resonant circuit comprises a passive load and an active circuit, at least one of the active circuit and passive load tuned to resonate at a resonant frequency. The driver is configured to drive the active circuit to output an RF signal at the resonant frequency, while the drive enable circuit generates a control signal to enable and disable the driver. The sample-and-hold circuit is configured to hold a peak level of the amplitude signal, and the measurement circuit detects a relative position and/or movement between the passive load and active circuit based on the held peak level. Corresponding systems, methods and apparatus are also described.

Provided is an electronic percussion instrument that is capable of simulating a playing technique for an acoustic percussion instrument. A tubular body part is opened on an axial end surface, and a head is attached to the axial end surface to be struck on the front surface. A capacitance sensor includes an electrode that generates a capacitance with respect to a detected conductor, such as a human body, positioned on the front surface side of the head. Because the capacitance sensor detects a change of a capacitance corresponding to a distance between the electrode and the detected conductor, whether the detected conductor approaches (contacts) the head or presses the head can be determined. As a result, the playing technique for the acoustic percussion instrument is simulated.
