The present subject matter provides various examples to power a portable VR host system that allows for free movement by the user. In various embodiments the present subject matter provides connections on the footwear of the user that supply electrical power to a VR host worn by the user. In various examples, a connection technology is employed to provide connections between the user wearing the VR host system and conductive mats, plates, or flooring that are powered to provide electrical power to the VR host system via connections to the user's apparel when standing. Other forms of connection technology may be employed, such as inductive wireless technology or radio frequency signal technology that uses wireless power coils or antennae to receive power and provide it to the VR host worn by the user. | 2019-02-14 |
20190052112 | OPEN CIRCUIT-BASED RX POWER LIMITER FOR WIRELESS POWER TRANSFER - A wireless power transfer system may wirelessly transmit and receive power. A transmitting coil may wirelessly transmit the power. A receiving coil may be magnetically but wirelessly coupled to the transmitting coil and may wirelessly receive the power and generate an AC input voltage. A rectifier may rectify the AC input voltage. A capacitance may filter the rectified AC input voltage. An electronic switch may be connected in series between the rectified AC input voltage and an output. A load may be connected to the output. A controller may open and close the electronic switch so as to cause the output to be at a constant DC voltage, notwithstanding variations in the load. | 2019-02-14 |
