Abstract: Systems and methods to determine if an individual is impaired. The system includes a display and a stimulus on the display. The system includes a controller programmed to move the stimulus about the display and one or more sensors that track eye movements and pupil size of a user due to movement of the stimulus or light conditions. The system includes a processor programmed to analyze the eye movements and pupil data size. The system is programmed to determine the drug, or category of drug, causing impairment. The method includes using and collecting data from a testing apparatus. The method includes processing the data with an automated impairment decision engine to determine whether a subject is impaired. The method includes using machine learning models or statistical analysis to determine whether a test subject is impaired. The automated impairment decision engine may be trained using machine learning and/or statistical analysis.

Abstract: A holesaw system comprises a holesaw including a base and a generally cylindrical wall with a proximal end coupled to the base and a distal end with a cutting edge; a pilot drill bit including a front cutting tip, a rear shank portion, and an intermediate portion between the front cutting tip and the rear shank portion; and an arbor coupleable to the holesaw and to the pilot drill bit. The arbor is configured to be operable in a first mode in which the holesaw and the pilot drill bit are rotatable in unison to form a hole in a workpiece and in a second mode in which the pilot drill bit is rotatable independently of the holesaw to remove a plug of material from the holesaw.

Abstract: Embodiments of the present disclosure relate to real-time digitally signing of a virtual object. The real-time digital signing of a virtual object is provided in a multi-user real-time context between signor and signee that enables the signor to perform the real-time digital signing and the signee to visually experience the real-time signing. The real-time digital signing may be provided to the signor and signee in parallel, and/or one or more additional viewers taking part in the digital signing. Upon completion of the digital signing, some embodiments in near-real-time generate a digital asset that is linked to the virtual object modified with the digital signature, which may be assigned to and/or otherwise linked with the signee for subsequent retrieval and/or use.

Abstract: A number of eye shades having a headband coupled to a transparent visor are disclosed. The visor extends downward from the headband so that it is positioned in front of a wearer's eyes when worn. The visor may have a resilient protective nosepiece attached thereto. The headband may be made of a flexible material that wraps around a top edge of the visor and is affixed thereto, such as by sewing or adhesive. The eye shade may be foldable including a foldable headband and vented end members that are attached to and fold behind the visor. The headband and visor may be attached to an interior surface of a hat to provide an item of headgear.
