Abstract
A method of and device for reducing energy consumption of a motion sensing device by reducing or avoid using function of device's internal GPS system when a predetermined condition is senses. The predetermined condition includes a predetermined state of motion or no-motion sensed. The motion sensing device includes Personal Emergency Response Systems.
Claims29
An energy saving method of a fall sensing device comprising:
- a) using a motion sensor monitoring an occurrence of a predetermined status over a predetermined period;
- and
- b) altering a pre-programmed GPS location checking action of the fall sensing device when sensing the occurrence of the predetermined status.
An energy saving method of a fall sensing device comprising:
- a) broadcasting a signal from a cradle of a personal emergency response system (PERS);
- b) establishing a physical location when a fall sensing device receives the signal from the cradle;
- and
- c) altering a pre-programmed GPS location checking action of the fall sensing device when the fall sensing device determines that the signal is received from the cradle.
1 more element
A power-saving fall sensing device comprising:
- a) an algorithm implemented motion sensor configured to detect a motion or lack of a motion over a predetermined period;
- and
- b) a power source configured to power a microcontroller that runs the algorithm, wherein the power source is periodically duty cycled by the microcontroller when a threshold condition of motion or lack of motion is achieved.
