An apparatus and method for use with a vehicle wheel balancing system (100) to obtain non-contact measurements of dimensions on a wheel assembly (200) secured on a spindle shaft (104), together with identification of, and distances to, operator-selected locations on various surfaces of a wheel assembly 200.

A balancing device for installing a counterweight in a specified shaft balancing region paired with a balancing plane includes a securing device which can be controlled via a control unit. The securing device has a first and a second receiving area for a counterweight or the shaft at a free end. A slot is arranged on the balancing device such that the balancing device can be moved along the shaft in the axial direction. The balancing device has a sensor for ascertaining the position of the balancing device relative to the shaft. The balancing device further includes a display unit which is connected to the control unit so as to exchange data and which is designed such that the position of the balancing device relative to the balancing region can be displayed.

A weight applicator including a weight applicator head and at least one actuator is disclosed. The weight applicator head is adapted to carry a wheel balance weight and has a weight application surface with a weight retaining region and a leading rotation region. The at least one actuator is coupled to the weight applicator head for manipulating the weight applicator head in at least one direction. The at least one direction has a radial component. The leading rotation region is oriented to extend radially further than the weight retaining region.

Apparatus and associated methods relate to apparatus for balancing a fan. In an illustrative example, a fan balancing system may include a local device and a remote device. For example, the local device may include a sensing unit and a processing unit. The remote device may, for example, include a user interface and a controller wirelessly coupled to the local device. For example, the controller may receive a user input including a total number of blades of a fan from the user interface. When the fan is activated, a condensed imbalance profile may be received wirelessly from the local device releasably coupled to the fan. In some implementations, the controller may generate a balancing matrix including combinations of weights and positions of the weights along one or more blades of the fan. Various embodiments may advantageously generate a placement combination of weights to re-balance the fan remotely.

A system for converting an input oscillation having an input frequency into an output oscillation having an output frequency is disclosed. The system comprises: a controller configured for receiving the input oscillation and responsively generating a multi-component drive signal. A frequency of at least one component of the drive signal is other than two times the input frequency. In some embodiments, a frequency of another component of the drive signal equals about two times the output frequency. The system also comprises an oscillator for generating pump oscillations responsively to the drive signal and applying parametric excitation to the input oscillation at the pump oscillations.
