Abstract: Systems and methods are disclosed that provide smart alerts to users, e.g., alerts to users about diabetic states that are only provided when it makes sense to do so, e.g., when the system can predict or estimate that the user is not already cognitively aware of their current condition, e.g., particularly where the current condition is a diabetic state warranting attention. In this way, the alert or alarm is personalized and made particularly effective for that user. Such systems and methods still alert the user when action is necessary, e.g., a bolus or temporary basal rate change, or provide a response to a missed bolus or a need for correction, but do not alert when action is unnecessary, e.g., if the user is already estimated or predicted to be cognitively aware of the diabetic state warranting attention, or if corrective action was already taken.

Abstract: A stir weld tool of the present invention is used to weld two pieces of metal together through frictional heating, plasticizing, mixing, and forging of the plasticized metal into a uniform weldment. The stir weld is accomplished by rotating the stir weld tool with a pin having at least one boss on its surface to create the mechanical friction in the metal in contact with the rapidly rotating pin. As the rotating pin travels along the weld joint, the plasticized metal of the work pieces is extruded to the back face of the pin while undergoing a mechanical stirring and forging from action imparted by the at least one boss on the surface of the pin, and while confined from above by the pressure exerted on the metal by a shoulder on the stir weld tool.

Abstract: The three dimensional probe device of the present invention is mountable on a working end of a fully automated and articulated robotic arm movable through at least five degrees of axial freedom in a global dimensional reference. The three dimensional probe device comprises a base, a carriage, a probe, a Z axis measuring apparatus and a tilt measuring apparatus. The probe tip contacts the work piece surface to be traced with deflections in the workpiece seam or path resulting in movement of the carriage and probe. The probe includes a plate and a ball which is pivotable in a ball socket portion of the carriage. Movement of the carriage in relation to the base provides measurement data for rotational change in the direction of the workpiece path or seam. Tilting of the probe provides measurement data for translational change in the direction of the workpiece path or seam.

Abstract: Multiple large screens on movable arms form a gateway beneath which viewers may walk. The screens slide up or down, i.e., toward or away from, the viewers walking below. The screens also pivot in a circular arc to sweep toward, or away from, the viewers. In one embodiment a number of vertical support beams are employed. Elongated arms are attached to the support beams at one end so that the arms can each be rotated about their attached ends. The arms also slide up and down the length of the support beams. Projection screens are attached to the arms so that the screens move as the arms move. In a more specific embodiment each screen is provided with a rear-projection projector for displaying images onto the screens. A computer is used to control the sliding and rotating of the support beams so that preprogrammed patterns can be executed. A computer is also used to control the projectors so that coordinated patterns of images are displayed on the screens.
