Abstract: A system for energy-usage optimization is a system that monitors the power delivered to at least one power distribution system. Each power distribution system includes at least one power storage unit and a multiway additive switch. The multiway additive switch enables the power distribution system to selectively provide power from an sub-circuit, from the at least one power storage unit, and a combination of both the sub-circuit and the at least one power storage unit. The system may serve as a stand-alone apparatus that is connected in between the sub-circuit, through an outlet, and an electrical load. The system increases power delivery, reducing the wait-time of an electrical load to reach maximum performance. Electrical loads, preferably appliances, are no longer limited by instantaneous power availability of the sub-circuit.

Abstract: A method of providing feedback for a piece of cue-sport equipment, a cue ball or cue stick, during a game play first collect spatial positioning and orientation data from a plurality of measurement sensors that is integrated into the cue-sport equipment. Then, the collected data is analyzed to generate a virtual movement model of the cue-sport equipment as the virtual movement model includes a calculated impact force diagram, an animated travel path, and a calculated absolute orientation for the cue-sport equipment. Then, the player can view the virtual movement model through an external computing device to improve their cue-sport skills effectively and efficiently.

Abstract: One or more processors may be configured to receive, via a radio from one or more sensors, one or more streams of sensor values indicating: (1) accelerations of a boxer's arm within a first range of acceleration, measured by a first acceleration sensor, (2) accelerations of a boxer's arm within a second range of acceleration, measured by a second acceleration sensor, and (3) rotation of the boxer's arm measured by a gyroscope sensor. The one or more processors may be configured to determine, based on the received sensor values from the first acceleration sensor, whether a punch landed but not to measure a force or velocity of the punch. The one or more processors may be configured to determine, based on the received sensor values from the second acceleration sensor, at least one of a force or a velocity of the punch but not to detect whether the punch landed.

Abstract: Sensor systems and methods for quantitative assessment of sports performance are disclosed. In one embodiment, a boxing data server comprises a memory storing predetermined profiles of arm acceleration or rotation over time for one or more types of punches, a radio for communicating with one or more sensors on one or more boxers, and one or more processors. The one or more processors may be configured to receive, via the radio from the one or more sensors, one or more streams of sensor values indicating: (1) accelerations of a boxer's arm within a first range of acceleration, measured by a first acceleration sensor, (2) accelerations of a boxer's arm within a second range of acceleration, measured by a second acceleration sensor, and (3) rotation of the boxer's arm measured by a gyroscope sensor. The one or more processors may be configured to determine, based on the received sensor values from the first acceleration sensor, whether a punch landed but not to measure a force or velocity of the punch.
