Abstract: The time difference of arrival for a signal received at two or more receiving sites as transmitted from a wireless communications device, is determined by a frequency domain technique. The constituent frequencies of the signals received at the two or more receiving sites are determined, including the phase, or a value representative of the phase, of each frequency component. The phase values for the same frequency are subtracted to yield a phase difference values as a function of frequency. The slope of the function represents the time difference of arrival for the wireless communications device signal as received at the two receiving sites. To determine the mobile location based on the determined time difference of arrival values, a seed or initial location is first assumed for the wireless communications device and the distance difference of arrival (the time difference of arrival multiplied by the speed of light) is calculated.

Abstract: A light controller device to control illumination characteristics of a light system, the device comprising a plurality of switches wherein each switch is operable to select at least one of a color of light and a pattern of light colors, a plurality of lights to illuminate at least one of a color of light and a pattern of light colors based on which switch of the plurality of switches is selected, a viewer window where the plurality of lights illuminates through the viewer window when the switch is selected, and a structure to hold the plurality of switches, plurality of lights, and viewer window.

Abstract: A third brake light apparatus for a truck, the apparatus comprising an attachment comprising a front side, a top side and a back side wherein the attachment fits over an upper edge of a tailgate, a reflector cover comprising a top surface connected to the top side of the attachment, a light within the reflector cover, and a wire assembly connected to the light at a first end and comprising a connector at a second end for connecting the cord to a brake light system in the truck.

Abstract: An illuminated display assembly includes a flexible, translucent and rectangular display plate having an outer edge including two opposing side edges and two opposing end edges, and an image depicted on the display plate within the outer edge of the plate. The display plate also has a width dimension measured from the opposing side edges. The display plate is mounted to a support frame having a rectangular panel and a support member extending along a periphery of the panel. The support member includes two opposing side supports and two opposing end supports. A retainer is disposed along each of the side supports and the support frame has a dimension measured from the retainer on the side support that is less than the width of the display plate. Thus, when the retainer receives respective side edges of the display plate, the display plate deforms in a convex shape with respect to the support frame.
