An apparatus, system, method, and computer program and computer program product are provided for constraining the movement of a graphical hand when the physical hand controlling the graphical hand does not have a similar physical constraint. The constraining technique may comprise use and analysis of a revolute-joint-link-spring model. In such a model, an uncompressed / unextended spring position represents the corresponding measured joint angle or link position. In addition to linear springs which follow Hook's Law, i.e., F=k*x, non-linear springs or other non-linear force functions may be employed to obtain the desired result of allowing a graphical joint or link to deviate from what the corresponding measured joint or link provides. In particular, if a graphical hand configuration corresponding to measured joint and link positions causes a portion of the hand to penetrate a simulated graphical solid object, a mathematical determination is used to compute modified joint and link positions such that the graphical hand part will no longer penetrate the graphical solid object. Such a constraint technique may include solving a spring model such that the various joint and link springs compress or extend to produce modified joint and link positions. Such a constraint technique may also be applied to constrain other graphical body parts and graphical inanimate objects, where corresponding physical controlling, i.e., measured, body parts and inanimate objects do not possess a similar constraint or impediment.

A novel hybrid stochastic gradient adaptation apparatus and method for calibrating the gain of an RF or non-RF digitally controlled oscillator (DCO). The adaptation algorithm determines a true stochastic gradient between a forcing function and its corresponding system measure to estimate the system parameters being adapted. A momentum term is generated and injected into the adaptation algorithm in order to stabilize the algorithm by adding inertia against any large transient variations in the input data. In the case of adaptation of DCO gain KDCO, the algorithm determines the stochastic gradient between time varying calibration or actual modulation data and the raw phase error accumulated in an all digital phase locked loop (ADPLL). Two filters preprocess the observable data to limit the bandwidth of the computed stochastic gradient providing a trade-off between sensitivity and settling time.
