A power harvesting system for providing energy to operate a coupled electrical device. The power harvesting system comprises a charging device and a wireless switching device operably coupled to the charging device. The charging device is configured for charging the wireless switching device and comprises a first RF transceiver for communicating with the wireless switching device and a power transmitter for imparting power to the wireless switching device. The wireless switching device comprises a second RF transceiver for communicating with the charging device, a power receiver operably coupled to the power transmitter, the power receiver configured for receiving power from the power transmitter, a rectifier circuit coupled to the power receiver, the rectifier circuit configured for converting the received power into DC energy and at least one ultra-capacitor electrically coupled to the rectifier circuit, the ultra-capacitor configured for storing the DC energy.

Power harvesting systems

The present invention discloses a system and method for directing an object generating a sensory output to a user through wireless means. The object does not have an embedded battery but derives power from radio frequency electromagnetic wave energy through the use of an RF energy harvesting module. Once selectively activated, the object provides an output to its user. Such output can be utilized in a variety of entertaining, useful or productive means.

System and method for directing a small scale object to generate a sensory output to a user powered by rf energy harvesting

The invention discloses a computer peripheral non-contact sensing device and a method thereof, wherein the sensing device comprises a sensing unit, a controller and a transmitting unit. The sensing device can detect a digital pointing device and generates induction signals. The controller outputs start signals or stop signals in different proportions in time series according to the induction signals so as to lead the transmitting unit to dynamically generate oscillation signals that are transmitted to the digital pointing device, so that the power source consumed by the non-contact sensing device can be saved greatly.

Computer peripheral non-contact inputting device and method thereof

A radio-frequency mouse is adaptable to receiving electromagnetic wave transmitted by electronic devices. The radio-frequency mouse comprises a radio-frequency transceiver module, an inductor, a microcontroller, a battery and a power supply management circuit, wherein the radio-frequency transceiver module receives electromagnetic wave and then converts the electromagnetic wave into radio-frequency power, the inductor outputs operating signals according to operated conditions of the radio-frequency mouse, the microcontroller transmits the operating signals to the radio-frequency transceiver module, the radio-frequency transceiver module emits the transmitted operating signals to the electronic devices, the batteries provide battery power, the power supply management circuit receives the radio-frequency power, and the radio-frequency power or battery power can be provided to the inductor and the microcontroller selectively according to the radio-frequency power. The radio-frequency can be supplied with power when the radio-frequency power is higher than a preset value, thereby saving power of the battery of the radio-frequency power while increasing continuous service capacity of the radio-frequency mouse.
