Short range wireless powered ring for user interaction and sensing
First Claim
1. A finger-worn ring that harvests short range wireless energy, comprising:
- a small interaction area on an outer portion of the finger-worn ring facing towards the palm of a user'"'"'s hand, the small interaction area comprising actuators arranged in a pattern comprising a center actuator and actuators surrounding the center actuator in a circular pattern on the interaction area to sense user input actions for controlling items displayed on a display;
an inductor and circuitry that is used for scavenging of short range wireless energy from a device that is transmitting the wireless energy for a purpose other than charging;
a battery that stores the scavenged energy; and
a microprocessor that monitors battery level and decides when to activate energy scavenging to charge the battery; and
a wireless link that communicates the user input actions to a computing device using the scavenged energy stored in the battery to control items displayed on a display of the computing device using the communicated user input actions.

Abstract
In general, the short range wireless powered ring described herein pertains to a finger-worn ring. In one embodiment the ring has a small interaction area towards the palm of the hand that employs sensors to sense user input and can interpret this input and other data. For example, the ring can interpret user input as scroll and select input actions. The ring communicates user interactions and other data wirelessly using a low-power wireless solution. The ring contains a coil and other circuitry for energy harvesting from short range wireless enabled devices such as, for example, NFC enabled phones, while users interact with their devices. A built in rechargeable battery is used to store the scavenged energy. The ring may also contain physiological and inertial sensors. The ring can provide a readily available input device of small form factor that has an easily accessible energy source for ease of use.
