    Abstract: A multi-wavelength optical reflector comprises a diffraction grating structure (18) which comprises a plurality of repeat grating units (20) in which each grating unit (20) comprises a series of adjacent diffraction gratings (22, 24, 26) having the same pitch. The grating units (20) and adjacent gratings within a grating unit are separated by a phase change (28) of substantially pi (&pgr; radians). The lengths of the gratings (22, 24, 26), which are different for each grating within a grating unit, are selected so as to provide a predetermined comb reflection spectrum which comprises a plurality of reflection maxima of substantially equal reflectivity.

    Abstract: The array is highly suitable for producing a spacially wide output “beam” (comprising a number of individual beams). It suffers less from problems of hotspots and filamentation since each tapered laser supports a limited number of modes, or even a single mode. Therefore it produces a semiconductor laser which is especially suitable for pumping of other lasers and to be used in materials processing.

    Abstract: A tuneable laser is disclosed, including a gain section with first and second comb reflectors to one side thereof. The two reflectors each provide combs with substantially uniform spacings, the spacings differing as between the combs. Each comb reflector can be tuned so as to shift the reflective peaks of the combs, thus allowing alignment of a single reflective peak at a chosen wavelength which is the same in both combs, forming a supermode. This supermode has an intensity greater than the threshold of the gain section and thus the laser produces an output at that selected wavelength.

    Abstract: A wheeled vehicle includes a front steered wheel, a rear driven wheel, and a support member that supports a rider. A main structural tube is disposed substantially horizontally along a longitudinal axis for supporting the front steered wheel at a forward end of the main structural tube, for supporting the rear driven wheel at a rear end of the main structural tube, and for supporting a rider who controls and steers the wheeled vehicle. An improved torsion acting shock absorbing mount is disclosed for the cantilevered shock absorbing support of at least one of the vehicle wheels from the frame. The torsion acting shock absorber includes a square sectioned metal tube, a correspondingly square sectioned metal shaft, and confined compressible resilient compound rods acting there between. The torsion acting shock absorber is attached at right angles to the main structural tube. A cantilevered wheel support is mounted offset from the main structural tube at the end of the shock absorber remote from the main structural tube. The square tube fastens at right angles to the main structural tube while the square metal shaft connects to the cantilevered wheel support. The cantilevered wheel support torsion rotates through the shock absorber at right angles with respect to the main structural tube to undertake shock absorbing movement between at least one of the wheels and the main structural tube, and the rider.

    Abstract: Provided is a method for managing sets of OSGi bundles in a manner that enables a developer to control the order in which bundles are activated, both within and among OSGi start levels. Also provided is a method for eliminating multiple instances of the OSGi class loaders that are typically generated for each bundle. A bundle consolidator tool is provided that combines multiple bundles in a set of bundles into a master bundle that appears to the OSGi framework to be a single bundle. An activator method enables the developer to specify the order in which individual bundles are initiated and terminated. In addition, a single class loader thread is employed to activate the individual bundles. The bundle consolidator tool also analyzes the target bundles for name space collisions and, in the event a collision is detected, the tool is programmed to modify byte codes to eliminate the collision.

    Abstract: Method and apparatus for providing GPS pseudorange correction and carrier phase correction information for navigation or surveying activities over a selected geographic region S of arbitrary size. In a navigation mode, a virtual reference station (VRS), positioned near a selected location L, receives differential GPS (DGPS) correction signals, translates these signals into a selected format, and broadcasts this DGPS information in this format for use by a local user. In a survey mode, the VRS receives corrected GPS information, translates this information into a selected format and broadcasts this translated and corrected GPS information and the VRS location, for use by a mobile station in forming a baseline vector from the GPS mobile station to the VRS location.

    Abstract: A system and method for reclaiming memory occupied by compiled code resulting from a Just-in-Time (JIT) compiler is provided. An address space used to store code resulting from a JIT compiler is memory mapped using a special filesystem. A map is maintained identify method name and corresponding JIT pages. When the memory manager needs more space, it requests that the special filesystem write the data from memory back to nonvolatile storage. The special filesystem acts as if the data was written. When the code is subsequently called, a page fault and an invalid operation exception occur and are handled. The data in the map is used to recompile the method to the same address space and the faulting instruction is re-executed.
