摘要:
A board-type game to be played by two or more players. The game includes lasers where players selectively divert the path of the laser beams. The board apparatus comprises a surface, bounded by a frame, over which laser beams are directed down symbolic rows and columns which constitute a matrix of squares. Each square is a subregion of the surface piece, and is bounded along its four sides by raised edges which are parallel and perpendicular rows and columns of the board. The raised edges, creating recessed squares, assist in orienting the playing pieces. Playing pieces may contain no mirror, one mirror, or two mirrors (oriented back-to-back to produce separate surfaces reflecting in opposite directions). Playing pieces are placed in a predetermined “starting” configuration on the squares of the gridded surface piece. Depending on whether a playing piece contains a mirror or not, said piece may reflect an incident laser beam from a row to a column or from a column to a row. A laser is placed in a predetermined position, in front of each player. The players alternate in moving pieces from square to square or rotating pieces in place, on the gridded surface, with the object of either directing their laser beam toward the opponent's “key” piece or preventing their opponent's laser beam from reaching their own “key” piece.

A laser tissue fusion device is optimized for particular surgical applications to join tissue layers. The device has two opposed arms that engage and disengage to clamp and release layers of tissue therebetween. The distal end of the first arm is disposed opposite the distal end of the second arm. A laser energy source generates therapeutic laser energy is either integrated within the device is a separate unit. An energy pathway transmits the laser energy to the distal end of the first arm to deliver the laser energy to tissue layers clamped between the distal ends of the arms. An actuator decreases the separation distance between the distal ends of the arms to clamp the tissue layers. A switch activates the laser energy source upon engagement. The laser energy source delivers a burst of energy at a predetermined wavelength for a predetermined period of time sufficient to spot-weld the tissue.

In an active region of an optical-electronic semiconductor device, nitrogen is incorporated in a barrier adjacent a GaNAs-based (e.g., GaInNAs) quantum well to improve device performance at wavelength bands above 1.2 microns. In a specific example embodiment, a mirror or cladding layer is grown over the active region in a manner that removes nitrogen complex otherwise present with Ga—N bonds in the active region. The embodiment can be implemented as one of a number of configurations including vertical cavity surface emitting lasers (VCSEL) and edge emitting lasers.

An endorsement system is provided for enabling a user to manage endorsements and promotions. In an embodiment, the user may be able to embed a logo of a company within the user's profile picture within a social network. Such user, displaying the logo of a company may thus act as an endorser of the company, and in exchange the company may offer the user certain incentives for such endorsement. The endorsement may be viewed by the user's friends of connections within a social network. In one embodiment, the endorsement system includes an administration system, the administration system including one or more modules to permit a user to create a profile, manage the user's profile, and manage endorsements.

Medializing the middle turbinate in the nose has been realized as a solution to the common complication of adhesions following nasal and sinus surgery. The invention provides a system for medializing the middle turbinate by attaching the middle turbinate temporarily to the nasal septum. The attachment is performed using a wafer with means on both sides for attaching the wafer to a mucosal surface. The attachment may also be performed using a tissue adhesive, pins, or other medical devices described herein. The invention also provides a system for attaching the uvula to the nasopharyngeal side of the soft palate. The invention provides a medical device for use in the inventive procedures as well as methods for the procedures and kits for use by a physician.

A golf bag rain cover is used to cover a club opening of a golf bag so that the golfer's clubs can remain as dry as possible during play. The golf bag rain cover may comprise a one-piece shell being constructed of a water-resistant material which is held in a bonnet shape over the club opening by several extensible rods. The golfer simply reaches up and under the shell to retrieve or replace clubs. In alternate embodiments, the deployment of the rain cover can be adjusted to allow more or easier access to the clubs. Also in alternate embodiments, the rain cover may be stowed in a stowage element integral with the golf bag.

Controller calibration methods for use with sampled getting distributed Bragg reflector SGDBR laser (102) is presented. An exemplary method includes conducting a two-dimensional mirror current scam of each front mirror current setting and back mirror current setting for a sampled grating distributed Bragg reflector SGBDR laser(102) to produce laser setting data corresponding to each front mirror current setting and back mirror current setting to generate a reference optical signal (114) of the SGDBR laser (102). A channel operating point is determined for each channel within the two-dimensional scan data A fix up of the operating point to substantially minimize wavelength and power error can also be performed A two-dimensional control surface is characterized at the channel operating point for each channel. A lookup table for controlling the SGDBR (102) laser is generated from the operating point currents, locker values and two-dimensional control surface data from each channel.

A portable picnic table for tailgate parties is disclosed that attaches to a trailer hitch receiver of a vehicle. The table includes a frame having a transverse main beam, vertical supports extending upwardly from the main beam, and a mounting member extending forwardly from the main beam. The mounting member has a forward end adapted to be received in a trailer hitch receiver of a vehicle. First and second seats are attached by pivot connections to the respective ends of the main beam, and a table top is attached by pivot connections to the upper ends of the vertical supports. The seats and table top are each movable between a horizontal use position and a vertical transport position. The pivot connections are constructed such that the seats and table top must be lifted vertically from their vertical transport positions before they can be pivoted to their horizontal use positions. A trailer hitch receiver is provided at the rear of the mounting member for attaching a trailer or a support stand behind the table to stabilize the table during use.
