Title: Method and apparatus for storing surplus adss cable
Inventor: FORRESTER JOSEPH H
IPC: G02B6/48
Filed: 1998-07-20
Abstract: A method of storing surplus ADSS cable includes steps of laying out a length of cable along an serial route defined by a series of poles and forming loops of surplus cable at occasional pole. The cable is raised to a predetermined installation at each pole. Two dead-ends (12, 14) at the pole secure the ends of the loop so that the loop (20) is substantially free of tension. The center of the loop is raised and secured to the pole while maintaining the minimum bend radius. thus forming two bights in the loop. A bend radius protector 40) is installed in each of the bights to protect the cable. Each bend radius protector is suspended from a cable protecting sleeve (50) placed over the taut cable (10), so that the cable is not damaged.

Inventor: DAHLMAN ERIK BENGT LENNART
IPC: H04J13/00
Filed: 1998-10-23
Abstract: A novel format is provided for an uplink common physical channel in a random access mobile communications system, whereby a mobile station transmits a first packet including a predetermined signature pattern (206, 210) in parallel with a second packet including the data part (212, 216, 220) of the random access request.

Patent CA-2326864-A1 (CA)
Title: Eye-gaze direction detector
Inventor: HUTCHINSON THOMAS E
IPC: G06F3/01
Filed: 2000-11-24
Abstract: A system for eye-gaze direction detection is disclosed that uses an infrared light emitting diode mounted coaxially with the optical axis and in front of the imaging lens of an infrared sensitive video camera for remotely recording images of the eye of the computer operator. The infrared light renters the eye and is absorbed and then re-emitted by the retina, thereby causing a "bright eye effect" that makes the pupil brighter than the rest of the eye. It also gives rise to an seven brighter small glint that is formed on the surface of the corner. The computer includes software and hardware that acquires a video image, digitizes it into a matrix of pixels, and then analyzes the matrix to identify the location of the pupil's center relative to the glint's center. Using this information, the software calibrates the system to provide a high degree of accuracy in determining the user's point of regard. When coupled with a computer screen and a graphical user interface, the system may place the cursor at the user's point of regard and then perform the various motile clicking actions at the location on the screen where the user fixates. This grants the individual complete control over the computer with solely their eye. The technology is not limited to determining gaze position on a computer display;  the system may determine point of regard on any surface, such as the light box radiologists use to study x-rays.
