Abstract: Aspects of the present disclosure describe systems, methods, and structures—including LiDAR—that employ multiple detectors that may determine multiple incident angles of multiple received radiation beams and advantageously do not require or employ phase shifters in illustrative embodiments and may instead—employ optical Fourier transform structures.

Abstract: Aspects of the present disclosure describe systems, methods, and structures for optical phased array calibration that advantageously may be performed as a single-pass measurement of phase offset with respect to only a single interference measurement. In sharp contrast to the prior art—systems, methods, and structures according to aspects of the present disclosure advantageously produce phase offsets and phase functions of each element without time-consuming iterative procedures or multiple detector signals as required by the prior art.

Abstract: Aspects of the present disclosure describe systems, methods, and structures providing speckle reduction in photonic phased array structures.

Abstract: A phototherapy device for treating neonatal hyperbilirubinemia comprises a plurality of LEDs coupled to a support structure configured to absorb and dissipate heat generated by the LEDs without requiring a fan. The LEDs provide a uniform dose of radiation on a treatment surface of the subject over a distance range of 20 cm to 45 cm. The support structure can comprise a heat-conductive metal plate. The LEDs have an emission range of 400 nm to 520 and a light output intensity of at least 30 ?W/cm2/nm and at most 65 ?W/cm2/nm at the treatment surface. The device can be adjustably coupled to a mounting structure. Power supplied to the LEDs is adjustable based on the total number of hours of use of the LEDs, the intensity of the LED radiation, the distance between the LEDs and the treatment surface, and/or the tilt or orientation of the phototherapy device.

Abstract: A fishing pole with leverage bar comprising a fishing pole, where the fishing pole includes a rod and a handle; a leverage bar attached to the handle, where the leverage bar is positioned parallel to the handle; a pair of fasteners to attach the leverage bar to the handle, where the pair of fasteners enable movement of the leverage bar from an extended position to a retracted position. The fishing pole with leverage bar provides a convenient armrest upon which a fisherman rests their arm while retrieving in a fish.

Abstract: A laser-based infrared countermeasure (IRCM) system is disclosed. The IRCM system includes a set of receive optics, a dichroic filter, first and second detectors, a lens module and a laser. Receive optics are configured to receive optical information. The lens module reflects the optical information from the receive optics to the dichroic filter. The dichroic filter selectively splits the optical information to the first and second detectors. The first and second detectors, each of which is formed by a single-pixel detector, detects a potential missile threat from the optical information. Based on information collected by the first and second detectors, the laser sends laser beams to neutralize any missile threat.

Abstract: A self-inking hand stamp tool for generating a stamp on a surface. In an embodiment, the self-inking hand stamp tool comprises a base, a carriage operatively coupled to the base, a stamp operatively coupled to the carriage, an inkpad operatively coupled to the base, and a housing operatively coupled to the base, wherein operation of the housing transfers the stamp from an inking orientation to a stamping orientation. The stamp may further comprise a stamp plate selectively couplable to the carriage and one or more stamp sheets selectively adherable to the stamp plate. In an embodiment, the one or more stamp sheets are selectively adhered to the stamp plate via an electrostatic force.
