  • Patent number: 10209149
    Abstract: An installation method and an apparatus of a strain gauge sensor are capable of driving an object to be measured to generate a deformation signal by a pushing/pulling force. At least two strain gauge sensors are installed on surfaces with different amounts of deformation and at an installation location of an electrical vehicle according to the installation method. The installation method includes Method 1: When a manual pushing/pulling force is applied, the installation location is deformed and the deforming action force is directly proportional to the pushing/pulling force. Method 2: When the pushing/pulling force is applied, the vehicle deforming direction at the installation location is independent to the pushing/pulling force moving direction. Method 3: The strain detecting direction of the strain gauge sensor is the same as the vehicle deforming direction at the installation location. Therefore, pulling or driving force data can be measured accurately.

  • Patent number: 8594952
    Abstract: A method for determining mechanical power dissipation in a vibratory system, assuming the system is linear time-invariant and steady-state. The method includes the steps of identifying connection points between the vibratory system and components outside the vibratory system. The acceleration is measured at each connection point in a windowed time domain and the force at each connection point is also determined for the windowed time domain. The time domain values are converted into the frequency domain values by the fast Fourier transform, and the frequency domain acceleration values are converted to velocity values. The power dissipation of the vibratory system then equals the summation of one half of the power flow into the vibratory system. Here, each power flow is one half of the real part of the product of complex-conjugated velocity times force at the connection point in the frequency domain for each time window.

Each instance of the previously stored sensor data is associated with a medical diagnosis. If the received sensor data matches any of the previously stored sensor data based on the comparison, then an injury risk indicator is generated based on at least one of the medical diagnosis associated with the matching previously stored sensor data or an impact history of the user. The generated indicator is presented.

  • Patent number: 8370087
    Abstract: A bicycle power meter has a strain gauge sensor assembly mounted on a relatively compressible portion of the end of the rear fork of the bicycle frame. The relatively compressible portion is near the rear hub and subject to the forces exerted by the cyclist to the crankset, and transferred via the chain, and sprocket assembly to the hub. The sensor assembly has two ohmically interconnected stretch sensors each having a first layer bearing a variable resistance element, whose resistance changes with displacement of the compressible portion, and a second layer for providing support for the first layer. The sensor assembly is connected in a bridge circuit to two other resistances to generate signals representative of cyclist applied force. These signals are processed along with velocity signals to generate power signals and the power signals are supplied to a display.

  • Publication number: 20120278007
    Abstract: A method for checking the plausibility of a torque of an electric machine, calculated on the basis of a machine model, in which a first value of an electromagnetic power of the electric machine is determined from the calculated torque and a rotational speed of the electric machine. Stator current components and stator phase voltage components are calculated from the stator currents and the stator phase voltages with respect to a reference system, which is fixed in relation to the stator. A second value of the electromagnetic power of the electric machine is determined from the stator current components and the stator phase voltage components. If a deviation of the first value of the electromagnetic power of the electric machine from the second value exceeds a predefined power threshold value, the torque of the electric machine, calculated on the basis of the machine model, is classified as implausible.
