Abstract: Self-cleaning electrochemical cells, systems including self-cleaning electrochemical cells, and methods of operating self-cleaning electrochemical cells are disclosed. The self-cleaning electrochemical cell can include a plurality of concentric electrodes disposed in a housing, a fluid channel defined between the concentric electrodes, and an electrical connector positioned at a distal end of a concentric electrode and electrically connected to the electrode. The electrical connectors may be configured to provide a substantially even current distribution to the concentric electrode and minimize a zone of reduced velocity occurring downstream from the electrical connector. The electrical connector may be configured to cause a temperature of an electrolyte solution to increase by less than about 0.5° C. while transmitting at least 100 W of power.

In an example, an HMD includes a display; a facial interface frame at least partially surrounding the display; a removable facial interface attached to the facial interface frame; a first attachment mechanism attached to one of the facial interface frame or the removable facial interface; and a second attachment mechanism attached to the other of the facial interface frame or the removable facial interface, the removable facial interface being attached to the facial interface frame by the first attachment mechanism and the second attachment mechanism.

Abstract: A thermal camera system configured for Red-Green-Blue (RGB) to thermal image mapping and calibration of a thermal camera. The system may comprise a plurality of thermal cameras connected in a daisy-chain formation, and a computing device communicatively coupled to the base thermal camera. The computing device configured to accept a distorted RGB image, convert it into an array image, undistort the array image into an undistorted RGB image through use of a barrel transformation, map each corner element of the plurality of corner elements to a predefined coordinate to generate a thermal angular mapping, and map the thermal angular mapping to a distorted thermal image by a 2nd-degree parabola mapping process.

Abstract: Systems and methods are provided for measuring, assessing, predicting, improving and presenting the state of physical object and human core temperatures, using imaging devices, e.g., a thermal infrared camera, and/or intruders in a region of interest to an operator, such that little or no operator effort is required to install, use or receive reports from the system.

Abstract: A lidar pulse is time resolved in ways that avoid costly, fragile, bulky, high-voltage vacuum devices—and also costly, awkward optical remappers or pushbroom layouts—to provide preferably 3D volumetric imaging from a single pulse, or full-3D volumetric movies. Delay lines or programmed circuits generate time-resolution sweep signals, ideally digital. Preferably, discrete 2D photodiode and transimpedance-amplifier arrays replace a continuous 1D streak-tube cathode. For each pixel a memory-element array forms range bins. An intermediate optical buffer with low, well-controlled capacitance avoids corruption of input signal by these memories.

Abstract: A system for use in managing activity of interest within an enterprise is provided. The system comprises a computer configured to (i) receive sensor data that is related to key activity to the enterprise, such key activity comprising a type of object and the object's activity at a predetermined location associated with the enterprise, the sensor providing information from which an object's type and activity at the predetermined location can be derived, (ii) process the sensor data to produce output that is related to key activity to the enterprise, and (ii) store the information extracted from the processed data in a suitable manner for knowledge extraction and future analysis. According to a preferred embodiment, the object is human, machine or vehicular, and the computer is further configured to correlate sensor data to key activity to the enterprise and the output includes feedback data based on the correlation.

Abstract: Pushbroom and flash lidar operations outside the visible spectrum, most preferably in near-IR but also in IR and UV, are enabled by inserting—ahead of a generally conventional lidar receiver front end—a device that receives light scattered from objects and in response forms corresponding light of a different wavelength from the scattered light. Detailed implementations using arrays of discrete COTS components—most preferably PIN diodes and VCSELs, with intervening semicustom amplifiers—are discussed, as is use of a known monolithic converter. Differential and ratioing multispectral measurements, particularly including UV data, are enabled through either spatial-sharing (e. g. plural-slit) or time-sharing.
