Abstract: Electrical faults pose a significant risk to people and property. A system is described that deploys instrument devices with sensors to detect faults within an alternating current (AC) electrical distribution system. These sensors may detect electrical, optical, thermal, acoustic, radio frequency, and other phenomena associated with a fault. Data from different sensors may also be used to distinguish fault and non-fault status. Users are notified if a fault status is detected. Mitigating actions may be automatically taken, such as de-energizing a branch circuit associated with the fault status. Information about non-fault status may also be used to mitigate nuisance circuit breaker interruptions. In some situations, a nuisance interruption of a breaker may be automatically reset if all instrument devices connected to the breaker reported non-fault status before the interruption.

Abstract: An image sensor including a planar sensor array, a lens configured to form an optical image on the planar sensor array and characterized by a locus of focal points on a curved surface, and a cover glass with multiple thickness levels or multiple cover glasses of different sizes. The one or more cover glasses are configured to shift the locus of focal points for large field angles, such that there are multiple intersections between the planar sensor array and the locus of focal points for a large FOV, and thus multiple zones with best focus on the planar sensor array.

Abstract: A system, apparatus and method of improved measurement of the SPF factor of sunscreen compositions. In one embodiment, a method of measuring the protection of a sunscreen composition includes exposing skin to a known intensity of light, measuring the amount of remitted light from the skin, applying sunscreen to the skin, exposing the skin to which the sunscreen has been applied the known intensity of emitted light of the spectrum of light from which the sunscreen is intended to protect the skin, measuring the amount of light remitted from the skin, and calculating a UltraViolet-A Protection Factor (UVA-PF) of the sunscreen by comparing the amount of light remitted from the skin with the sunscreen to the amount of light remitted from the skin without the sunscreen.

Abstract: A method of generating a photon with multiple dimensions includes a step of generating a first photon encoded with quantum information in each of two or more frequency bins and at least one time bin. The method further includes performing a frequency dependent time operation to entangle (i.e. make non-separable) the frequency bins and the time bins in the photon.

Abstract: An operation method and an electronic device are provided. A phone call is established while a display of the electronic device is activated. A proximity sensor of the electronic device is turned on. A supply of power to the proximity sensor is controlled to emit light through a plurality of pixels in a portion of the display corresponding to a position of the proximity sensor and the light emitted by the proximity sensor and reflected by an object is received to identify a distance between the electronic device and the object, if the plurality of the pixels in the position corresponding to the proximity sensor are deactivated during the phone call. The supply of power to the proximity sensor is blocked if the plurality of pixels in the portion of the display corresponding to the proximity sensor are activated during the phone call.
