System and method for a motion sensing device which provides a visual or audible indication

摘要

A device includes a signaling means and a motion sensor, and logic for activating or controlling the signaling means in response to a sensed motion according to an embedded logic. The device may be used as a toy, and may be shaped like a play ball or as a handheld unit. It may be powered from a battery, either chargeable from an AC power source directly or contactless by using induction or by converting electrical energy from harvested kinetic energy. The embedded logic may activate or control the signaling means, predictably or randomly, in response to sensed acceleration magnitude or direction, such as sensing the crossing of a preset threshold or sensing the peak value. The visual means may be a numeric display for displaying a value associated with the count of the number of times the threshold has been exceeded or the peak magnitude of the acceleration sensed.

主权项

1. A device for signaling in response to a sensed motion, the device having a single enclosure, and in the single enclosure comprising:
an accelerometer attached to the single enclosure for producing an output signal responsive to the device acceleration; a visible light emitter that consists of, or comprises, a DLP display or a video projector, for emitting a visible light indicating a first status to the person; a software and a processor for executing the software, the processor coupled to the accelerometer and to the visible light emitter for activating or controlling the visible light emitter in response to the output signal; a rechargeable battery connected to power the device; and a generator operative convert the device kinetic energy to an electrical energy connected to charge the rechargeable battery.
