Abstract: A method for initiating a gesture-based mutual interaction scheme between a first and second mobile device, comprising: associating a gesture-based mutual interaction scheme between the first and second mobile device that associates a position scheme with a respective action, where the position scheme relates to any of: an absolute or relative orientation, and an absolute or relative trajectory; acquiring a first position property of the first mobile device and a second position property of the second mobile device; determining that each of the first and second position properties comply with the position scheme; triggering an execution of an action on the second mobile device, where the action is associated with the position scheme that the first position property complies with; where the second mobile device conditions the execution of the action triggered by the first mobile device on the compliance of the second position property with the position scheme.

Abstract: An inertial measurement system comprising at least one sensor cluster comprising a plurality of inertial sensors for sampling at least one of acceleration and angular velocity of said at least one sensor cluster with respect to each axis in a plurality of axes of a reference frame, and for producing individual outputs associated with said at least one of acceleration and angular velocity, at least three of said inertial sensors said sampling with respect to each same respective said axis; and a processing engine for receiving said individual outputs, combining said individual outputs to yield respective combined outputs, detecting which of said individual outputs diverges from at least one of their inter-comparison, and its respective combined output, according to a decision rule, said processing engine configured to dynamically self-calibrate a parameter that includes individual scale factor of those said inertial sensors whose said individual outputs were detected to diverge.

Abstract: A device for determining relative orientation between two locations including an imager, an inertial-orientation-sensor firmly attached to the imager for determining information relating to the orientation thereof and which exhibits drift and a processor coupled with the imager and with the inertial-orientation-sensor. The processor determines a first orientation-measurement and first time-tag when the device is oriented with a first-orientation-indicator located at a first location. The processor determines a second-orientation-measurement and second time-tag when the device is oriented with a second-orientation-indicator located at a second location. The processor determines a third-orientation-measurement and third time-tag when the device is oriented again with the first-orientation-indicator.

Abstract: A method for adapting electromagnetic (EM) field model parameters including the steps of minimizing the difference between a model for the measurements and one or more measurements. The minimizing may be done by estimating model parameters, and at least position and/or orientation. The model may further include system model parameters, wherein the system may include one or more sensors and one or more radiators.
