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 relates to target acquisition and related devices, and more particularly to telescopic gunsights and associated equipment used to achieve shooting accuracy at, for example, close ranges, medium ranges and extreme ranges

A highly energy efficient automobile that provides payload, safety and performance capacities similar to a comparable vehicle of a given vehicle class. The current invention is ideal for short to medium range urban and suburban driving. The current invention incorporates components in a unique and novel way, in which these components combine to form a system that produces an automobile that reduces overall air pollution while encouraging the commercialization of alternative energy sources. The current invention features an lightweight, low rolling resistance, digitally controlled and direct-drive electric propulsion system. A lightweight spaceframe with a suspension system provides a structure for mounting a low-aerodynamic-drag body system and other components. An intelligent power and thermal management system coupled with a removable auxiliary power module supplies the electrical energy required. While the preferred embodiment is substantially a passenger vehicle, the current invention may be scaled to other land vehicles.

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.

A communication system for communicating with a vehicle via a wireless personal communication device such as a smart phone. The communication system uses medium-range transceivers to extend the effective range of the communication system. A communication device accessory that includes a portable medium-range RF transceiver is coupled to the wireless personal communication device so that power for the portable medium-range RF transceiver can be drawn from the wireless personal communication device. The communication device accessory is electrically coupled to the wireless personal communication device via a wired connection that provides at least a wired electrical power connection and optionally a wired data connection between the communication device accessory and the wireless personal communication device.

The invention discloses a medium-range forecast system and method for cold, rainy and snowy weather based on atmospheric variable physical decomposition. By utilizing the atmospheric space three-dimensional multivariable and time continuous grid data outputted in the past observed, the current observed and the medium-range numerical weather prediction modes, and the physical decomposition of the climate and the weather disturbance quantity, a causality between the regional sustained low temperature, rain and snow and freezing extreme weather events and the weather disturbance prior to and during the events is established in the method.

The invention provides not only an inquiring system for historical low temperature, rain and snow and freezing weather events, but also a forecasting system for medium-range low temperature, rain and snow and freezing weather events.

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.
