Dynamic balance is the branch of mechanics that is concerned with the effects of forces on the motion of a body or system of bodies, especially of forces that do not originate within the system itself, which is also called kinetics.

Device for computerized dynamic posturography and a method for balance assessment

InactiveUS20080228110A1Determining and training an individual's ability to recover balanceStable functionPerson identificationSensorsUniversal jointDynamic balance
A device for balance training and assessing dynamic balance by measuring a subject's ability to react to perturbations. A universal joint assembly is translated at the base of a support plate while a top plate on which the subject stands is fixed against translation. The universal joint permits the attached top plate to rotate about at least one and preferably multiple axes, and the subject must control balance following the translation of the universal joint. All components are housed in a one-piece platform assembly, made up of two plates in which the components are mounted. An existing force plate measurement system is placed on the top plate, and the subject stands thereon during use. A virtual environment, by image-creating devices, may be used to create a realistic sensation of tripping and general postural instability, or shifting of the support surface.

Dynamic agent skill balancing

A computer implemented method, data processing system, and computer program product for dynamically balancing call loads among call center resources when a call load reaches a threshold. Responsive to receiving an incoming call at a call center, a target call center resource group is determined to handle the incoming call. A determination is then made as to whether a call load of the target call center resource group is above a threshold. If the call load is above the threshold, the least utilized call center resources in the call center are located. The resources in the least utilized call center resources which have a same skill set of the target call center resources are then identified. The identified resources are then assigned to the target call center resource group.

Controller of legged mobile robot

The occurrence of a slippage of a robot in operation, following a desired gait, is determined, and the permissible range of a restriction object amount, such as a floor reaction force horizontal component or a floor reaction force moment vertical component to be applied to the robot, is variably set according to a slippage determination result. A provisional motion of a desired gait is determined using a dynamic model, and if the restriction object amount defined by the provisional motion deviates from the permissible range, then the motion of a desired gait is determined by correcting the provisional motion by changing the changing rate of the angular momentum of the robot from the provisional motion so as to limit the restriction object amount to the permissible range, while satisfying a dynamic balance condition.

Center housing design for electric assisted turbocharger

An electric assisted turbocharger has an electric motor with a stator and a rotor that is coupled to a turbocharger shaft carried by a bearing assembly. The stator has a left-hand winding and a right hand-winding each projecting axially outwardly therefrom. The winds each extend a different distance radially along the motor (and are thus asymmetrical with respect to one another), thereby forming a radial gap along an axial end of the stator. The so-formed stator is disposed within a motor housing and together, the stator and motor housing, facilitate placement center housing axial end therein to minimize turbocharger axial length. The rotor is configured to prevent migration of oil into the motor housing, to improve dynamic balance, and comprises an integral thrust washer for placement against the bearing assembly.
