摘要： Apparatus and method for controlling an electric motor providing assistance to a bicycle rider based on measuring the mechanical power generated by the rider. The power generated by the rider is measured by measuring tension in a bicycle chain (or belt) and RPM. A chain (or belt) roller is carried at the free end of a cantilevered beam and the chain (or belt) rides over the roller. The resulting deflection of the cantilevered beam provides a measurement of chain tension. A control signal for the electric motor is generated based on a smoother version of the power generated by the rider.

摘要： A handheld apparatus (2) for checking the tension of the wire (15) includes a support (3) with two spaced pegs (5,6) mounted on it. A spring (7) mounted on the support (3) between the two pegs. A strain gauge (14) is mounted on the spring and measures the displacement of the spring (7). A fully portable power supply is connected to a computer (9) with a readout (8). In use, the wire (15) is arranged in a predetermined path over and/or under the pegs (5,6) so that it presses against the spring (7). The amount the spring (7) is displaced, which is related to the tension, is measured by the signal from the strain gauge. The signal is passed to the computer (9), which calculates the tension from this measurement and displays the result on the readout (8).

摘要： A web tension sensing device supports the end of a rotating roll by means of a housing. A bearing within the housing transmits forces to a beam which carries a strain gage. The beam is mounted within a cylindrical body which can be secured to a fixed structure in a variety of ways.The beam has a flat middle portion of reduced thickness, where the strain gage is located, and the forward end of the beam is fitted within the bearing, which is a spherical self-aligning bearing.

摘要： A measuring roller, which may be a driven chill roller provided with a coolant supply and return assembly, is utilized as a web tension measuring roller. A measuring cage includes a flanged ring fixed to a side frame of the printing machine and a retainer ring joined to a bearing for the measuring roller. These two rings are connected by a plurality of flectional beams that are provided with strain gauges. Changes in web tension are sensed by the strain gauges in response to deflection of the flectional beams.
