Disclosed are various embodiments of cross-wind turbines that are capable of providing high efficiencies over a wide range of wind velocities. An airfoil stator causes wind to accelerate along its surface and creates a low pressure area on the leading face of the rotor blade during the power stroke. A blocking stator blocks wind from impeding the movement of the rotor blades during the return cycle and directs wind onto the trailing face of the rotor blades during the power cycle. A large pressure differential is created between the leading face of the rotor blade and the trailing face of the rotor blade during the power cycle which creates a large amount of force that rotates the rotor blade about the central shaft. In some embodiments, gaps are provided between the inside edge of the rotor blade and a stationary shaft which vents wind collected by the rotor blade during certain portions of the rotation cycle. The vented wind increases the pressure on the trailing face of the rotor blades during the return cycle to further assist in the efficiency of this system.

In an access control system, a method and system for dynamic channel selection to select a channel for communication between a Wireless Access Point Module (WAPM) and a Wireless Panel Interface Module (WPIM). A number of communication channels are available. The WAPM attempts to communicate over a first channel and selects a second channel if the first channel is unsuccessful. The WPIM scans all the available channels so that communication may be established regardless of the channel chosen by the system. Alternatively, the available channels may be segmented into groups and an individual WAPM may be assigned to a group of channels rather than a single channel.

A thermal detecting device for sensing temperature at multiple locations proximate to the detecting device is provided. The detecting device has a pair of infrared detectors each configured to measure temperature of two locations by receiving infrared energy of the two locations. A housing encloses the pair of infrared detectors. The housing is configured with an aperture to allow the infrared energy of the two locations to be received by the pair of infrared detectors. A reflective mirror or two mirrors focus the infrared energy of the two locations towards the pair of infrared detectors. The detecting device may be configured to determine if there is a temperature differential at a location as the housing moves with respect to the location.

A vehicle vision system displays a vehicle pathway image that includes a reticle for visually identifying the in-path portion of the image. A reticle array is disposed between a video camera chip and a lens, and includes a conical or frustro-conical region of substantially un-attenuated light transmissivity surrounded by a region of perceptibly attenuated light transmissivity, such that in-path portions of the displayed image are substantially unchanged and out-of-path portions of the displayed image are perceptibly attenuated. The reticle array may also include a number of reduced transmissivity lines traversing its conical or frustro-conical region to produce a series of receding stadia lines in the in-path portion of the displayed image, enabling the driver to reliably discern the range of displayed objects.

A back-up system for aiding a driver in backing a motor vehicle performs a number of functions when a motor vehicle is placed in a reverse direction. Initially, an image of an area at the rear of the motor vehicle provided by a camera is visually displayed on a monitor, which is positioned so as to be visually accessible by a driver of the motor vehicle. Then, a distance to an object that is within a path of the motor vehicle is sensed with a radar sensor. Next, a warning is provided when the object is within a predetermined collision distance. Finally, when the motor vehicle is placed in a forward direction, the display of the image on the monitor is discontinued.
摘要:
A near-field radar apparatus includes a fixed beam planar radar antenna and a radiation pattern adaptation device disposed substantially at the near-field boundary of the antenna. The adaptation device comprises a plurality of dielectric elements that individually constitute or approximate different surface portions of an idealized quasi-spherical or quasi-cylindrical radome reflector. The dielectric elements can be maintained physically separate or combined about the diffraction point of the antenna to form a single dielectric element. The dielectric elements may be mounted on a radome that is otherwise transparent to the radiation pattern, or otherwise suspended at or near the near-field boundary of the antenna.
