摘要： The present invention pertains to systems and methods for measuring power output, as in an athletic activity such as cycling. One embodiment relates to a force sensing device configured to be mounted on the bottom surface of a shoe as part of a mechanical linkage through which force is exerted. For cycling, the force sensor is mounted on the bottom surface of a cycling shoe and fitted with a cleat that interlockingly engages a bicycle pedal. To measure both positive and negative pressures on the pedal, the force sensor is pre-stressed with a compressive load to an intermediate point in its dynamic range. Strains that further compress or decompress the force sensor can thus be measured. The computing module mathematically converts the measured pressures, positive and negative, to a measurement of total power exerted by the rider. In addition, the computing module may utilize cyclical regularities in the signal to compute the rider's cadence (pedal revolutions per unit of time). Data from the force sensor is transmitted wirelessly to a remote display where it can be viewed by the rider.

摘要： A display unit for displaying the output of a vehicle engine measures and displays the output or torque of the engine during a normal running state.The unit calculates and displays the output of the engine according to an intake air quantity and engine rotational speed. The unit calculates an output for a predetermined steady run corresponding to a present vehicle speed. If the engine output calculated according to the intake air quantity and rotational speed is smaller than the steady-run output, the unit displays zeros.

摘要： A method and apparatus for determining the power output of a gas turbine engine utilizes a speed sensor coupled to the engine shaft and a signal developed by a pyrometer coupled to the engine turbine for determining engine temperature. The speed sensor is normally provided in the engine for determining shaft speed and is part of the control system for the engine. The pyrometer is provided also as part of the control system to monitor gas turbine temperatures. A signal from the speed sensor derived from a toothed wheel passing adjacent the sensor is processed to obtain a train of pulse signals representative of angular rotation of the engine shaft. The pyrometer is mounted adjacent at least one of the turbine disks of the engine for detecting instantaneous temperature of each blade of the turbine disk as it passes by the pyrometer. The signal developed by the pyrometer is therefore a signal having peaks corresponding to passage of each blade at the pyrometer. A signal conditioning apparatus processes the signal from the pyrometer to develop a pulse train of shaped signals corresponding to the angular position of each turbine blade as it passes by the pyrometer. The system determines the relative phase difference between the signals developed by the speed sensor and the signals developed on the pyrometer under low load conditions and stores this information as a reference phase difference value. Phase differences under load conditions are thereafter compared to the reference value. The differences in phase are proportional to shaft twist and accordingly to shaft torque.

摘要： The system measures horsepower at the drive wheels of a truck tractor under conditions which very closely simulate actual road conditions. For each set of drive wheels there are a driver roll and an idler roll mounted on a frame for rotatably supporting the drive wheels, and a dynamometer is connected to measure the power transmitted from the tractor drive wheels to the drive roll. A hydraulic cylinder and piston rod unit is mounted to the support frame and extends rearwardly. A flexible link connects the movable end of the hydraulic cylinder and piston rod unit to the fifth wheel on the tractor for forcing the tractor wheels against the driver roll while removing weight from the idler roll - thus transmitting the entire torque at the drive wheel to the driver roll while leaving full control of the applied load in the hands of the operator. The driver roll and idler roll for one set of drive wheels is mounted on a movable chassis for accommodating all wheel bases; and the idler rolls are independently movable relative to their associated driver rolls for controlling the distribution of traction between the driver and idler rolls. In a modification, the pulling angle of the flexible link may be set for further controlling the application of torque to the driven roll.
