Abstract: A device mountable on a shaft of exercise equipment is provided. The device comprises: a housing with a hole therethrough to receive an end of the shaft; a load sensor configured to generate an indication of weight of a load attached to the shaft; a motion sensor configured to generate an indication of motion of the load over time; and an interface configured to transmit, to an external device, (i) the indication of weight of the load and (ii) a time series descriptive of a trajectory of the load over a period of time. The external device is configured to apply a set of one or more processing rules to the indication of the weight and to the time series to generate a metric of forces applied to move the load along the trajectory and provide the metric via a user interface of a client device.

Abstract: Disclosed is a simple, analytical method that can be utilized by hydrogen filling stations for directly and accurately calculating the end-of-fill temperature in a hydrogen tank that, in turn, allows for improvements in the fill quantity while tending to reduce refueling time. The calculations involve calculation of a composite heat capacity value, MC, from a set of thermodynamic parameters drawn from both the tank system receiving the gas and the station supplying the gas. These thermodynamic parameters are utilized in a series of simple analytical equations to define a multi-step process by which target fill times, final temperatures and final pressures can be determined. The parameters can be communicated to the station directly from the vehicle or retrieved from a database accessible by the station. Because the method is based on direct measurements of actual thermodynamic conditions and quantified thermodynamic behavior, significantly improved tank filling results can be achieved.

Abstract: A telematics-navigation device detects that a hybrid vehicle propelled by at least two energy sources is traveling to a destination not provided to the vehicle (i.e., an unknown destination). As the vehicle travels to the destination, the device identifies a road segment between a current position of the vehicle and a next road junction that vehicle is traveling towards. A control unit determines an optimization strategy for managing the energy sources of the vehicle as the vehicle travels the road segment. The control unit executes the determined strategy.
