Abstract: The present invention provides an apparatus comprising an RF energy harvester and an RF energy meter. The RF energy harvester comprises an antenna, a rectifier, an energy storage module and light output module. The antenna is arranged to receive an RF signal. The rectifier is arranged to generate a DC voltage from the received RF signal. The energy storage module is arranged to store the DC voltage. The light output module is arranged to output light pulses using the stored energy. The RF energy meter comprises a light detection module, a control module and an output module. The light detection module is arranged to detect light pulses output by the light output module of the RF energy harvester. The control module is arranged to count the number of light pulses detected by the light detection module. The output module is arranged to provide an output indicative of an amount of energy harvested by the RF energy harvester based on the counted number of light pulses.

Abstract: Various embodiments are described herein related to positively reinforcing user behavior based on a user behavioral action performed by a user and detected by one or more sensors. For example, one disclosed embodiment relates to a behavior reward system including a wireless sensor configured to transmit behavior data generated in response to an interrupt generated by an accelerometer included in the wireless sensor and a server computing device including a data-holding subsystem configured to hold instructions executable by a logic subsystem, the instructions being configured to determine whether the behavior data indicates that the user behavioral action was performed and if the behavior data indicates that the user behavioral action was performed, supply a reward offer to the user.

Abstract: Various embodiments are described herein related to positively reinforcing a behavioral action based on information received from sensors configured to detect the action. For example, one disclosed embodiment relates to a method for positively reinforcing a user behavior includes, at a server computing device, receiving behavior data from a sensor configured to sense a user behavioral action. Responsive to the behavior data, the method further includes using a logic subsystem of the server computing device to supply an offer configured to reward the user behavioral action and sending the offer to the user.

Abstract: An Internet enabled or networked communication device facilitates peer-to-peer voice messaging and impromptu conversations between multiple users across a network. Embodiments of the invention provide direct or multiple party voice messaging and real-time communication over the Internet using a device controlled by voice commands. These embodiments create a more natural and informal method for engaging in conversation that increases the effectiveness of personal communication, particularly for those who are handicapped or have difficultly with conventional communication interfaces. Embodiments provide a simple, yet highly configurable system that enables users to securely communicate with each other in a peer-to-peer fashion without using a local server.
