Abstract

A motion control assembly includes a motion control device electrically connected to a battery pack and to a mobile computing device for at least data transmission therebetween. The motion control device can generate inputs, such as inputs corresponding to an attribute of a sensed object, for transmission to the mobile computing device. The drain on a battery of a battery-powered mobile computing device can be reduced when used with a motion control device as follows. A motion control assembly, comprising a motion control device and a battery pack, capable of powering the motion control device, as an integral, one-piece unit, is selected. The motion control device is connected to an electrical connector of a battery-powered mobile computing device. The motion control device is supplied with power from the battery pack during use so the motion control device can be operated using the power from the battery pack.

Claims

1. A battery-powered motion control assembly for use with a mobile computing device, the motion control assembly comprising:

a motion control device comprising an emission module, including an illumination source, and a detection module, including a sensor;

a battery pack connected to the motion control device to supply power thereto, the battery pack being capable of powering the motion control device;

a coupler electrically connecting the motion control device to the mobile computing device for at least data transmission therebetween;

the motion control device capable of determining from an input power level to the mobile computing device from the battery pack when a low power required condition exists so that any operation needs to be a low power mode of operation; and

the motion control device further

detecting the existence of objects including objects sufficiently large to meet a threshold for reduced power consumption; and

instructing at least one of the emission module and the detection module to enter a low power mode of operation upon the detection of said sufficiently large objects.

2. The assembly according to claim 1, wherein the motion control device generates inputs for transmission to the mobile computing device.

3. The assembly according to claim 2, wherein the inputs correspond to an attribute of a sensed object.

4. The assembly according to claim 1, wherein the battery pack and the motion control device form an integral unit.

5. The assembly according to claim 4, wherein the coupler includes a plug, for connection to the mobile computing device, and a cable connecting the plug to the motion control device.

6. The assembly according to claim 1, further comprising a protective case configured for mounting to a mobile computing device, a portion of protective case carrying the motion control device, battery pack and coupler as a one-piece unit.

7. The assembly according to claim 1, the battery pack further comprising a coupler to electrically connect the battery pack to a solar panel.

8. The assembly according to claim 1, the motion control device further comprising:

an environmental filter to provide environmental information comprising an input power are level and power source type.

9. The assembly according to claim 1, the motion control device further:

adapting detection of objects to at least one of an input power level and a power source type.
