Title: Diffuser for light from light source array and displays incorporating same
Inventor: WHITEHEAD LORNE A
IPC: G09F9/35
Filed: 2005-07-15
Abstract: An optical structure placeable between a backlight array of point light sources and a planar display. The structure distributes light emitted by the point light sources to uniformly illuminate the plane of the display, without introducing significant viewing parallax. The emitted light is partially collimated within a preferred angular viewing range, maximizing the display's luminance when viewed from the normal direction. The structure is highly reflective, such that a substantial portion of any non-emitted light rays are internally reflected by the structure, increasing the likelihood that those rays will be subsequently emitted by the structure.

Title: Method and devices for secure measurements of time-based distance between two devices

IPC: H04L29/06

Abstract: In order to provide a secure measurement of Round Trip Time (RTT), the calculation of RTT and the authentication data are separated. A device A (212) sends a message (222) to device B (216) to start the method. Both devices generate (224; 226) a random number (Random_A, Random_B) and device A waits (228) for device B to finish. Device A sends (242) its random number to B, which answers (246) with its own random number, and device A calculates (250) the RTT. If the RTT is below a certain limit, device A then requires (252) authentication data, which is calculated (262) by device B and sent (264) to device A that verifies (266) the authentication data. The RTT can thus be securely calculated regardless of the calculating resources of device B. Alternate embodiments, a system and devices are also provided. ® KIPO & WIPO 2008
