Title: Method and apparatus for improving vision
Inventor: GRIERSON JONATHAN
IPC: A61F9/01
Filed: 1996-10-17
Abstract: Methods and apparatus are disclosed for causing the optical center of the eye to align "HIGH point" of the anterior surface of the cornea. In accordance with one aspect of the invention relating to corneal ablation procedures, the "HIGH point" ( 14) of the eye is used as the pole of a spherical surface which is fitted approximately to a portion of the anterior surface of the cornea within a "bounded region" (16). For corneal ablation procedures, the "bounded region" comprises a generally inverted cup shaped region of the anterior surface of the eye bounded at its periphery by a plane (BP) which is substantially perpendicular to a local z-axis. During the operation local high points which project above the spherical surface are ablated. According to another aspect of the invention relating to radial keratotomy procedures, a pair of incisions (b, b') in the plane of a "great circle" are formed in the cornea to weaken and flatten it. As used herein, a "great circle" is formed by a plane containing the "HIGH point" and parallel to the local z-axis. The "bounded region" for radial keratotomy procedures is defined absolutely in terms of a circle projected onto the corneal surface which is centered about an axis passing through the "HIGH point" and parallel to the z-axis.

Patent CA-2245060-A1 (CA)
Title: Adjustable stop for line weight
Inventor: GRIMES DAVID A
IPC: A01K91/06
Filed: 1998-08-13
Abstract: A stop is used with fishing rigs having sliding line weights on a fishing line. The stop can be clamped onto the line at any location as a stop for the weight. A long snell is no longer required. The stop can be released as required to allow the line to be reeled in as far as required to land a fish or to store the rig safely. The stop is a hollow body that will not pass through the eye of the weight, and a pin that slides into the hollow body. The line passes through a transverse bore through the pin. When the pin is drawn into the bore in the body, the line is jammed between the pin and the body, to clamp the stop in place. The pin may have a head on one end to capture the stop body between the line passing through the transverse bore and the pin head. With this arrangement, the stop may be self releasing. Sufficient tension applied to the line will pull the pin end out of the body. The stop will come free to slide along the line. Alternatively the stop may be set up for manual release.

Title: Method and apparatus for mitigating intermodulation effects in multiple-signal transmission systems
Inventor: DENT PAUL W
IPC: H04B7/26
Filed: 1997-09-30
Abstract: Method and apparatus for mitigating intermodulation distortion effects in frequency division multiple access (FDMA) communications systems. In one embodiment, an effective transmit power level is determined for each communication signal to be transmitted, and signals are allocated to frequency channels such that a smooth tapering or transmit power levels across contiguous frequency channels is achieved. Such smooth power tapering across frequency channels minimizes the possibility that two high power signals will generate an intermodulation distortion product sufficient to disrupt transmission of an immediately adjacent low power signal. In another exemplary embodiment, communication signals are allocated such that high power signals are positioned near a frequency band center, while low power signals are positioned near frequency band edges. As a result, intermodulation distortion between frequency bands in a multiple-band communication system is also minimized.
