Disclosed herein is a method for repeat paging in a wireless communication system. In accordance with the method, a RAN controller will send a repeat-paging directive to a plurality of BTSs to cause each BTS to begin broadcast of a series of page messages destined to a target mobile station. While transmitting the series, one of the BTSs will then receive from the mobile station a page response, and the BTS will responsively provide to the RAN controller a notification of the page response. In response to receipt of the notification, the RAN controller will then send a paging-stop directive to at least each other BTS of the plurality, and each BTS that receives the paging-stop directive will responsively discontinue broadcasting the series of page messages before completing broadcast of the entire series of page messages, thereby helping to conserve air interface resources.

An apparatus, method, and system for distributing gas and/or liquid phase substance from an inlet to multiple outlets with reduced variations and distribution. The apparatus includes a body having an inlet and a plurality of outlets. In one aspect, a rotatable impeller is positioned between inlet and plurality of outlets. The impeller includes a spiral fluid pathway relative to direction of substance through the inlet so that the substance passes through the impeller and is distributed to the outlets through a spinning impeller.

A GaAlInP compound semiconductor and a method of producing a GaAlInP compound semiconductor are provided. The apparatus and method comprises a GaAs crystal substrate in a metal organic vapor deposition reactor. Al, Ga, In vapors are prepared by thermally decomposing organometallic compounds. P vapors are prepared by thermally decomposing phospine gas, group II vapors are prepared by thermally decomposing an organometallic group IIA or IIB compound. Group VIB vapors are prepared by thermally decomposing a gaseous compound of group VIB. The Al, Ga, In, P, group II, and group VIB vapors grow a GaAlInP crystal doped with group IIA or IIB and group VIB elements on the substrate wherein the group IIA or IIB and a group VIB vapors produced a codoped GaAlInP compound semiconductor with a group IIA or IIB element serving as a p-type dopant having low group II atomic diffusion.

Disclosed is a wheelchair having a pair of levers along its opposite sides connected with sprockets on drive wheels. In one form, each lever is connected to its sprocket by a rack. The drive wheels have a clutch enabling the power stroke of the lever to drive the wheels through the rack-and-pinion engagement, yet permitting the sprocket to rotate in the reverse direction freely upon the return stroke of the lever. The rack includes an arcuate extent void of teeth to enable disengagement of the drive connection between the lever and sprocket whereby the wheels may move freely in either direction. In another form, a chain interconnects the lever and a return spring connected to the wheelchair frame. The chain has an extent void of pins to enable disengagement of the drive connection between the lever and sprocket, whereby the sprocket and, hence, drive wheel are free to rotate in either direction. A speed change mechanism is employed to vary the torque applied to the sprocket by the lever.

This invention concerns a method of producing a Pepper's Ghost. The method may comprise projecting an image of a subject onto a reflective and transparent screen (7) to create a virtual image (15) of the subject alongside an object (21). The subject of the virtual image may have a colour temperature and the method may comprise illuminating the object (21) with light having a colour and intensity that results in a colour temperature of the object (21) at least approximately matching the colour temperature of the subject of the virtual image. The method may comprise altering the intensity of light that falls on the object (21) by moving the lighting arrangement towards or away from the object (21) whilst maintaining an intensity of light omitted by the lighting arrangement constant. The method may comprise projecting patterns (53) and/or images that would be achieved if the subject was actually present and light was reflected or transmitted by the subject and/or creating a shadow which the subject in the virtual image would make if the subject was actually present. The method may comprise creating two virtual images using the same foil. The method may comprise projecting an image of the subject onto the screen (7) onto a reflective bounce screen (4) and altering a distance between the projector and the reflective bounce screen (4) to move the virtual image.

Photoconversion devices comprising a semiconductor region of nanostructured crystalline material are disclosed. The nanostructures of a crystalline material provide for the generation of multiple excitons per photon absorbed by the crystalline nanostructure in response to incident solar radiation. The photoconversion devices will also include one or more optical elements providing for the concentration of sunlight in the semiconductor region. Also disclosed are photoconversion methods, systems and apparatus featuring the combination solar concentration with nanostructures of a crystalline material providing for the generation of multiple excitons per photon absorbed by the crystalline nanostructure in response to incident solar radiation.
