Abstract: Embodiments herein describe spectroscopy systems that use an unmodulated reference optical signal to mitigate noise, or for other advantages. In one embodiment, the unmodulated reference optical signal is transmitted through the same vapor cell as a modulated pump optical signal. As such, the unmodulated reference optical signal experiences absorption by the vapor, which converts laser phase noise to amplitude noise like the other optical signals passing through the vapor cell. In one embodiment, the unmodulated reference optical signal has an optical path in the gas cell that is offset (or non-crossing) from the optical path of the modulated pump optical signal. The unmodulated reference optical signal allows removal or mitigation of the noise on the other optical signal.

Abstract: The present invention provides implant devices comprising nanoscale structures on the surface thereof and methods of manufacturing such implant devices. In some embodiments, methods of manufacturing an implant device comprise exposing a surface of the implant device to an oxidative hydrothermal environment for a duration sufficient to generate nanoscale structures on the exposed surface(s) of the implant device.

Abstract: A dish drying rack includes a basin, a side bay pivotally connected with the basin for movement about a side bay pivot axis, and a plate rack pivotally connected with the basin for movement about a plate rack pivot axis. The basin includes a basin floor. The side bay moves between a collapsed position and an extended position. The side bay includes a side bay floor. When the side bay is in the extended position, the side bay floor is positioned with respect to the basin such that water drains from the side bay floor toward and onto the basin floor. The plate rack pivot axis is transverse to the side bay pivot axis. The plate rack is movable between an upright position and a flattened position.

Abstract: A system is provided to determine the gaze of a user. The disclosed system uses an array of light detectors, each located proximate to a light emitter. Light from the light emitters enters the eye and is partially reflected in by the retina. Light returning from the eye is detected by the light detectors and used to determine the gaze of the user.
