A broadband wireless network includes intelligent base stations and mobile units. The network includes control means to manage connectivity of the mobile units to the intelligent base stations. Software is provided to control connection of the mobile unit to an intelligent base station having preferred signal characteristics. When a mobile unit connects to an intelligent base station, the software broadcasts corrected routing information to all intelligent base stations on the network allowing persistent wireless connectivity.

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.

In a computer system having a host processor, a peripheral graphics device, a display screen, and a memory, a non-homogenous second order perspective texture mapping process. Polygon coordinates, a.sub.m,n, defining a texture polygon, are received. Initial values are received for a set of parameters including u.sub.main, v.sub.main, dv.sub.ortho, dv.sub.main, du.sub.ortho, du.sub.main, d.sup.2 u.sub.ortho, d.sup.2 u.sub.main, d.sup.2 v.sub.ortho, d.sup.2 v.sub.main, du.sub.ortho-ADD, and dv.sub.ortho-ADD. The texture polygon includes span regions. A span value, j, is set to an initial value to designate an initial span region of the texture polygon in (m, n) polygon coordinate space. The total number of rows, n.sub.max, is determined for the current span region of the polygon. The total number of polygon coordinates, m.sub.max, in the current row, n, of the texture polygon is determined. An (x, y) display coordinate, corresponding to the current polygon coordinate, a.sub.m,n, is set by translating from (m, n) polygon space to (x, y) display coordinate space. Texture coordinates, u(a.sub.m,n) and v(a.sub.m,n), are determined, according to the present invention, for each polygon coordinate, a.sub.m,n, using linear interpolation based on a set of relationships that utilize the above parameters without using a repetitive divide operation. A display pixel of a color determined according to texture coordinates, u(a.sub.m,n) and v(a.sub.m,n), is rendered on a display screen at the determined (x, y) position.

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.
