Abstract: Systems and methods for tracking user movement during physical fitness activities are presented. A camera tracks movements of objects of interest in a field of view thereof during an exercise routine to log, instruct and provide feedback data to assist the user in reaching fitness goals. The user can also share his data with friends or teammates, for example through social media or in a client-server environment.

Abstract: Nanoliter pipette assembly. The assembly includes a housing containing a working fluid in a working fluid chamber therein and includes a moveable piston within the housing, the piston moveable by a linear actuation mechanism for contact with the working fluid. A tip portion is provided that includes a diaphragm deformable to engage an inner portion of the tip. It is preferred that the diaphragm have a projecting three-dimensional structure for direct contact with a liquid.

Abstract: A device for calculating the speed of movement of a ball utilizing a sensing unit having an aperture at the surface of the ball and a receiving unit within the ball that measures reflected signals generated by the sensing unit. A distance measuring feature fixes a value for a particular distance of flight of the ball and a transducer receives a signal indicating the termination of the flight of the ball. A processor calculates the speed of the ball utilizing the absence of a reflected signal through the aperture and the beginning of a stop signal generated by the transducer as the basis for the time span of flight of the ball.

Abstract: An electronic drinking mug includes a mug having an outer surface, a heating element in thermal communication with the mug for heating a liquid disposed in the mug, and a temperature sensor in communication with the heating element. The mug has a controller in communication with the heating element for selectively activating and deactivating the heating element for heating the liquid in the mug to a desired temperature, and a user interface attached to the outer surface of the mug and being in communication with the controller for establishing the desired temperature of the liquid.
