Abstract: An apparatus for characterization of one or more light sources, has an image sensor array that defines an image plane having an imaging area. An aperture spaced apart from the image plane defines the field of view that includes, for each of the one or more light sources, a corresponding incident light path that lies along a central ray beginning at the corresponding light source, extending through a center of the aperture, and terminating at the image plane. A diffraction grating forms, on the image sensor array, for each corresponding light source, a light pattern having at least a zeroth diffraction order and a first diffraction order, wherein the zeroth diffraction order is a geometrical projection of the aperture along the central ray. A control logic processor identifies a wavelength range and angular direction within the field of view for at least one of the light sources.

Abstract: An impact detection device for detecting impacts to a body part of a user and various supporting systems are discussed. In an example, an impact detect device can include a circuit board, a component having a first section and a second section, a battery, and a molding for housing the circuit boat, the battery and the component. The circuit board can include impact detection circuitry including at least two sensors and a communication circuit. A zone of reduced rigidity can connect the first and second sections of the component, with the circuit board secured to the first section. The battery can be secured to the second section of the component allowing for flex relative to the circuit board. The molding can be shaped and dimensioned for mounting to a body part of the user.

Abstract: Systems and methods for mapping an explosive event are discussed. In an example, a system for mapping an explosive event can include a plurality of sensor devices and a data analysis system. Each of the plurality of sensor devices can include an environmental sensor to measure at least one parameter of an explosive event. Each sensor device can also include a time synchronization circuit to synchronize time stamping of the parameter measured by the environmental sensor, and a wireless communication interface. The data analysis system can access measurement data generated by the plurality of sensor devices and analyze the measurement data to produce a visualization mapping the measurements onto a virtual representation of the test environment.
