Abstract: A pushbutton and an electrical switch can be linked to one another so that movement of the pushbutton, for example by a user depressing the pushbutton, can control the switch. The switch can be in a closed position prior to being depressed and in an open position afterwards, or vice versa. A photodetector can be located on the switch side of the pushbutton. The pushbutton can be formed of a material that transmits light so that light can pass through the pushbutton for receipt by the photodetector. The pushbutton can additionally or alternatively be formed with an opening that is sized to receive an object inserted by a user. Insertion of the object can manipulate a second electrical switch, which may control flow of electricity from a battery, for example.

Abstract: A calibration method comprising, for each of one or more light sensors: (a) under influence of one or more substantially non-zero illumination levels in the target environment, using the light sensor to measure the sensed light level corresponding to each of these one or more illumination levels; (b) receiving a template light level value corresponding to each of the one or more illumination levels, representing the light level at a target location in the target environment substantially removed in space from the location of the light sensor, each of the one or more template light level values being assumed for the environment rather than measured by a light meter; and (c) determining a relationship between the sensed light level and the light level experienced at the target location, based on an evaluation of the one or more sensed levels relative to the one or more template light level values.

Abstract: The invention is directed to a method for measuring an internal thread of a workpiece with a coordinate measuring apparatus and a CCD or CMOS sensor. The sensor records at least two images of a section of the internal thread and the recording conditions for the two images are modified. The data from these two recorded images are used to establish the position, orientation, core diameter and/or the pitch of the internal thread. The invention is also directed to an arrangement for measuring an internal thread of a workpiece and includes a coordinate measuring apparatus and the CCD or CMOS sensor in accordance with the above method.

Abstract: The generation of photocurrent in an ideal two-dimensional Dirac spectrum is symmetry forbidden. In sharp contrast, a three-dimensional Weyl semimetal can generically support significant photocurrent due to the combination of inversion symmetry breaking and finite tilts of the Weyl spectrum. To realize this photocurrent, a noncentrosymmetric Weyl semimetal is coupled to a pair of electrodes and illuminated with circularly polarized light without any voltage applied to the Weyl semimetal. The wavelength of the incident light can range over tens of microns and can be adjusted by doping the Weyl semimetal to change its chemical potential.
