Abstract: An apparatus to treat refractive error of the eye comprises one or more optics configured to project stimuli comprising out of focus images onto the peripheral retina outside the macula. While the stimuli can be configured in many ways, in some embodiments the stimuli are arranged to decrease interference with central vison such as macular vision. The stimuli can be out of focus images may comprise an amount of defocus within a range from about 3 Diopters (“D”) to about 6 D. In some embodiments, the brightness of the stimuli is greater than a brightness of background illumination by an appropriate amount such as at least 3 times the background brightness. In some embodiments, each of a plurality of stimuli comprises a spatial frequency distribution with an amplitude profile having spatial frequencies within a range from about range of 1×10?1 to 2.5×101 cycles per degree.

Abstract: A methodology and system for performing radio network coverage surveys of multiple site candidates concurrently using one reserved channel based on reverse path signal strength measurements of a signal from a test mobile station transmitter (100) to a plurality of prospective base station receiver sites (200, 200?, . . . ) over a geographical area is presented. The instantaneous position, time-stamp and power of the Transmitter (101) is recorded and stored as it moves along a test route(s). Stationary Test Receiver(s) (201) tuned to the selected channel at each prospective site location (200, 200?, . . . ) save received instantaneous signal strength and, it's time-stamp so they can matched up to the position of the Test Transmitter (101) and used to ascertain received signal strength at each site. Results can be useful for ascertaining optimum site locations, antenna configurations, propagation model tuning, frequency planning, pilot planning and extraction of signal correlation statistics.
