Provided is an apparatus for driving an artificial retina using a medium-range power transmission technique. The apparatus can wirelessly transmit power to an artificial retina circuit within a medium range of about 1 m using resonance between a first coil equipped around a user's waist and a second coil implanted in a user's eye. Thus, it is possible to solve the difficulty of implanting a coil in a lens, provide convenience to a user by eliminating the necessity of artificial glasses, and stably supply power to the artificial retina circuit. In addition, it is possible to remarkably lessen the difficulty in connecting the second coil with the artificial retina circuit in an eye.

The present invention provides a method and system for peer-to-peer wireless communication over an unlicensed communication spectrum without routing or relaying of messages. Low-cost wireless communication is made possible by providing direct, peer-to-peer wireless communication without a need for extensive infrastructure as well as by utilizing unlicensed communication spectrums. Communication utility is afforded by enabling wireless communication over a medium-range distance, and by implementing a collision avoidance protocol.

A lightweight, low volume, inexpensive LADAR sensor incorporating 3-D focal plane arrays is adapted specifically for modular manufacture and rapid field configurability and provisioning. The present invention generates, at high speed, 3-D image maps and object data at short to medium ranges. The techniques and structures described may be used to extend the range of long range systems as well, though the focus is on compact, short to medium range ladar sensors suitable for use in multi-sensor television production systems and 3-D graphics capture and moviemaking. 3-D focal plane arrays are used in a variety of physical configurations to provide useful new capabilities.

Medium-range and global network information and control for a vehicle is achieved with a portable wireless key fob, a user-provided nomadic device, and a vehicle-installed telematics unit including a medium-range RF transceiver and a wireless network transceiver. The fob includes a medium-range RF transceiver for bi-directional communication with the telematics unit, and a short-range wireless transceiver for bi-directional communication with the nomadic device. The fob communicates with the telematics unit in a conventional manner, and also relays information between the telematics unit and the nomadic device. If a communication initiated via the fob cannot be completed because the fob is out of range, the communication is sent to the nomadic device for network transmission to the telematics unit. If a communication initiated via the nomadic device cannot be completed due to inadequate signal reception, the communication is sent to the fob for RF transmission to the telematics unit.

In an image enhancement method, a regular enhancement function and an aggressiveness parameter are computed using characteristics of a digital image. A first, relatively slow enhancement algorithm is applied to the digital image using the regular enhancement function, when an aggressiveness parameter is in a predetermined high range. A second, relatively fast enhancement algorithm is applied to the digital image using the regular enhancement function, when an aggressiveness parameter is in a predetermined low range. A modified enhancement function is calculated using characteristics of the digital image and is used with a second, relatively fast enhancement algorithm, when the aggressiveness parameter is in a predetermined medium range.
