    摘要： This sensor module has a strain-generating body that is made of metal and is adhered to an outer surface of a casing housing a battery; and a strain gauge that is provided to one surface of the strain-generating body and and uses a Cr mixed phase film as a resistor. A plurality of adhesion regions that are adhered to the casing and are separated from one another are demarcated on the other surface of the strain-generating body, and the strain gauge is positioned in a region of the one surface of the strain-generating body that is not opposite from said adhesion regions.

    摘要： Disclosed herein is a magnetic field generator that includes a solenoid coil, a soft magnetic body disposed in an inner diameter area of the solenoid coil, and a signal generating part configured to supply an AC signal to the solenoid coil. Since the soft magnetic body is disposed in the inner diameter area of the solenoid coil, the reach of a magnetic field can be significantly expanded as compared with when an air-core coil is used.

    摘要： A head mounted augmented reality display system comprising a hand held controller (306) comprising an emitter housing including a first electromagnetic reflector (820) including three first reflective elements (812; 814; 816) forming a first corner vertex of a first cube, wherein the first electromagnetic reflector defines a first coordinate space and the first corner vertex of the first cube lies at the origin of the first coordinate space; and an electromagnetic emitter (510) configured to produce an electromagnetic field, wherein the electromagnetic emitter is positioned along a line directed at point (1,1,1) in the first coordinate space; and a headset (301) comprising a right temple; a left temple; and a sensor housing (1075) mounted on at least one of the right temple or left temple, the sensor housing comprising an electromagnetic sensor (1070); and a second electromagnetic reflector (1072) including three second reflective elements forming a second corner vertex of a second cube.
