A wearable device according to an embodiment comprises: a substrate; a light-emitting unit disposed on the substrate; a light-receiving unit disposed on the substrate and spaced apart at a predetermined distance from the light-emitting unit; and a first reflection part disposed on the substrate adjacent to the light-emitting unit so as to reflect light emitted from the light-emitting unit.

Wearable device and operation method therefor

The disclosure provides a MEMS device including: a fixed substrate having a cavity; a driving unit disposed in the cavity and floating above the fixed substrate; and an elastic unit for physically connecting the fixed substrate with the driving unit and varying the height of the driving unit according to a control current, wherein the elastic unit includes a bimorph driving unit connected to the fixed substrate and bent according to the control current, a spring connected to the driving unit, and a frame connecting the bimorph driving unit to the spring. Therefore, in order to overcome the limitations according to the power consumption and the size-reduction due to a coil and a magnet, the MEMS device drives one lens and thus can reduce the power consumption and the size thereof.

A magnetic field sensor package according to an embodiment includes: a package body; a magnetic field sensor disposed on top of the package body and including a sensor assembly in which a displacement is generated by a magnetic field; and a conductive line formed on the package body, which is for making current to be measured flow and generating a magnetic field for displacing the sensor assembly, wherein the conductive line generates a magnetic field applied in a perpendicular direction to the sensor assembly.

Magnetic field sensor package

The present invention provides an amplitude modulator, which is disposed in an area through which a magnetic field flows so as to modulate amplitudes, comprising: a substrate; a first driving electrode which receives a first frequency signal and a second frequency signal supplied from the substrate and carries out resonant motion by the magnetic field; and a second driving electrode for receiving the second frequency signal and carries out resonant motion by the first driving electrode and the magnetic field, wherein a modulated signal is generated by modulating the amplitudes of the first and second frequency signals through the resonant motions of the first and second driving electrodes. Therefore, since the signal generated by modulating a carrier signal through mechanical resonance according to the magnetic field is outputted, amplitude modulation can be carried out without a complicated circuit configuration. In addition, since an MEMS device is a single structure that does not include an insulating layer, a single signal is applied to one structure, thereby simplifying driving, and all the driving electrodes of both ends thereof are driven so as to double a change in variable capacitance, thereby improving sensing ability.

In general, in one aspect, the disclosure describes a method that includes selecting an offset between start of communications of a first radio in a multi-radio platform (MRP) and start of communications of a second radio in the MRP. Synchronizing clocks of the first radio and the second radio to maintain the offset. Determining safe zones within the communications of the second radio based on configuration of the first radio and the second radio and the selected offset. The safe zones are locations that minimize conflicts between receiving operations of the first radio that are at fixed locations and transmitting operations of the second radio and transmitting operations of the first radio that are at fixed locations and receiving operations of the second radio.
