Motion control assembly with battery pack
View Patent ↗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.
1. A method for reducing a drain on a battery of a battery-powered motion control assembly when used with a mobile computing device, the battery-powered motion control assembly comprising a motion control device and a battery pack, the motion control device being capable of being powered by the battery pack, the motion control device comprising an illumination source and a sensor, the method comprising:
determining sensed input power information including an input power level; and
determining from the sensed input power information whether a low power required condition exists, and whenever the low power required condition exists:
provide the motion control device with instructions indicating a low power mode of operation is to be entered;
further provide to the motion control device the sensed input power information including the input power level;
adapt detection of objects by the motion control device to conditions indicated in the sensed input power information including the input power level; and
wherein the adapt detection of objects comprises performing object detection on objects sufficiently large to meet a threshold thereby reducing power consumption.
2. The method according to claim 1 , wherein the low power required condition determining comprises accessing power information from the mobile computing device and from the battery-powered motion control assembly.
3. The method according to claim 1 , wherein:
the sensed input power information determining further comprises determining a power type; and
the sensed input power information provided to the motion control device further comprises the power type.
4. The method according to claim 1 , wherein the adapt detection of objects comprises driving the illumination source with less power and/or for lesser amounts of time to reduce power consumption.
5. The method according to claim 1 , wherein the adapt detection of objects comprises reducing a capture rate of the sensor thereby reducing power consumption.
6. The method according to claim 1 , wherein the adapt detection of objects comprises using power from the mobile computing device by the motion control device.
