Abstract: The exercise performance monitoring glove consists of a pair of flexible gloves that have embedded pressure sensor arrays to measure hand pressure applied to them during physical activities such as exercise. Each glove sends its pressure data in a real-time format using an embedded wireless RF transmitter to the opposite glove. The gloves then compare the pressures and provide feedback through a user selectable choice of either audio, visual or vibratory methods. Audio feedback is provided to earbuds using typical connection means such as Bluetooth connection to a smartphone or remote device having an exercise performance monitoring app. Visual feedback is provided in several possible modes such as text, color, and graphics using an embedded wraparound flexible display screen. Vibratory feedback is provided using embedded vibration devices inside the gloves.

Abstract: Improving the operations of a computer system that is located within a power grid and that is associated with its own power sources. Past operational characteristics of the power grid are analyzed to derive learned characteristics for the power grid. Future operational characteristics of the power grid are also monitored. A prediction regarding a future load event associated with the power grid is then generated using the learned characteristics and the monitored characteristics. In response to this prediction, one or more operations are performed to balance the computer system with the power grid during the future load event, and to ensure a determined availability of services associated with the computer system during the future load event.
