A theft detection system includes an accelerometer attachable to an object, the accelerometer providing an acceleration signal in response to movement of the object; an alarm mechanism for providing a signal in response to movement of the object; and for preventing false alarms, a filter programmed to determine the frequency of the acceleration signal and to provide an output to activate the alarm mechanism only when the frequency of the acceleration signal meets a predetermined criteria.

Theft detection system and method

A motion-based input system including a motion sensor coupled to a device. The motion sensor provides a motion signal corresponding to the movement of the device. The system further includes a processor responsive to the motion signal and configured to distinguish between a tap command and a position command and provides, in response to a tap command, one or more actions, and in response to a position command, one or more different actions to control and operate the device.

Motion-based input system for handheld devices

A motion password control system including a motion sensor responsive to motion of a device and providing a signal corresponding to movement of the device; a database including stored data values corresponding to predetermined motion of the device; and an electronic circuit, responsive to the motion sensor, configured to compare the motion sensor signal with the stored database values, and, in response, to provide an output signal for performing at least one action of a preselected set of actions when the comparison reveals that the device has moved in a way which corresponds to the stored data values.

Apparatus for continuous sensing of hand and arm gestures comprises hand-held means for continuously sensing at least tempo and emphasis. These sensed parameters are represented quantitatively, and transduced by appropriate circuitry into electrical signals indicative of the parameter quantities. The signals may be used to control the performance of a musical composition (or the evolution of some other dynamic system), or may instead convey information. The signals may, for example, be provided to an interpreter that dynamically infers control commands from the gestures on a real-time basis in accordance with the generally accepted canon of musical conducting, directing the controlled system in accordance therewith. The invention may also sense one or more additional conducting parameters such as the speed and/or velocity, direction (i.e., trajectory) in three dimensions, absolute three-dimensional position, the 'size' of a gesture in terms of the spatial distance between successive beats, and the 'placement' of a beat pattern in space.
