Abstract: A method for reducing speckle patterns of a three-dimensional holographic reconstruction is disclosed. A controllable light modulator into which a three-dimensional scene is coded is illuminated by coherent light, a reconstruction means projects the modulated light close to an eye position into a space of observation and a control means controls the illumination. This provides a holographic reproduction device in which the speckle patterns occurring during reconstruction of a three-dimensional scene are reduced. Also provided is a next-to-real time method using a carrier medium of conventional image refresh rate.

Abstract: The invention relates to a controllable illumination device for an autostereoscopic or holographic display, which illumination device contains an illumination matrix of primary light sources having at least one luminous element per light source and a controllable light modulator (SLM) and a reproduction matrix. A computer-generated hologram (CGH) illuminated by the primary light sources (11, . . . , 1n) is coded on the controllable light modulator (SLM) and generates, in at least one plane downstream of the SLM, a matrix—reconstructed from the computer-generated hologram (CGH)—of secondary light sources (2) having a secondary light distribution for the purpose of illuminating the reproduction matrix (4) and for the purpose of focussing in light bundles onto each eye of the viewer via an imaging matrix. The CGH is calculated and reconstructed on the basis of the number of and the positions of the viewers and the system parameters.

Abstract: A cutterhead for cutting aquatic vegetation, includes a cutterhead shroud, stationary teeth secured to the shroud, and a drum rotatably mounted within the shroud and bearing a flight of vanes cooperating with the teeth to cut vegetation. In accordance with the non-binding aspect of the cutterhead, each vane has an edge that rises gradually from a trailing end adjacent (during drum rotation) to a stationary tooth, to provide a clearance area adjacent the vane into which a respective tooth may be deflected during cutting without impinging upon an associated vane, and thus without causing binding of the cutterhead in the event of such deflection. Each vane may have a curvilinear edge extending from its cutting end to a surface of the drum at its trailing end. The edge defines a two-dimensional profile having a trailing end tangent forming an angle of not more than 70 degrees with the drum.

Abstract: In a holographic projection apparatus a virtual visibility region is magnified, for observing a reconstructed scene with at least one light modulation device and with at least one light source having sufficiently coherent light for generating a wavefront of a scene that is coded in the light modulation device. By means of imaging the wavefront into a viewer plane, it is possible to generate the virtual visibility region for observing the reconstructed scene. The virtual visibility region has at least two virtual viewer windows. In this case, the virtual viewer windows are dimensioned such that the reconstructed scene can always be observed without tracking of the viewer windows upon movement of a viewer in the viewer plane.

Abstract: A video holographic display device includes a light source used to illuminate a hologram-bearing medium encoded with a hologram. The device operates so that only when an observer's eyes are positioned approximately at the image plane of the light source can the holographic reconstruction be seen properly. This contrasts with conventional holographic displays, in which the observer's eyes do not have to be at the image plane in order for a holographic reconstruction to be seen.

Abstract: A holographic projection system has an optical wave tracking system which adjusts the propagation direction of a modulated wavefront. It provides an adjustable wave tracking system which aligns the modulated wave with a desired eye position of one or more observers and follows the movements of the observer. The system comprises spatial light modulation means which modulate a wave with holographic information for the purpose of holographic reconstruction. The optical wave tracking provides the light path of the modulated wave with a desired propagation direction which guides the modulated wave out of the reconstruction system via a light exit position of a display screen. Position control means set adjustable tracking mirror means in terms of their inclination to a reflection direction for reflecting the modulated wave and deflection means, which are located in the set reflection direction, reflect the wave via the display screen into the desired propagation direction.

The holographic reconstruction system includes deflection control means for controlling the deflection means to sequentially adjust the visibility region to different contiguous viewing positions, and light controlling means for switching the light waves in synchronicity with the deflection control means.

Abstract: The present invention is a method, system, and computer program product enabling multiple versions/releases of a J2EE application to be served to clients from a single application server. One or more JNDI proxies are situated between each client and the application server. The JNDI proxies allow a same public “service name” to be utilized by different clients to access different programs/services on the application server. The JNDI proxies do this by translating the service name into a non-public “alias name” on behalf of the client. The alias name is a private name that the service provider who administers the application server understands and uses to locate the specific version of programs/services that the clients need.

Abstract: A mobile telephone can be configured to interact with external services by using a client application on the telephone that interacts with several external services via an intermediary server. The server sends, to the mobile telephone, configuration information to enable or disable defined sets of functionality in the application, the configuration information depending on and appropriate to the particular external service selected on the mobile telephone and being sent automatically to the mobile telephone over-the-air. An implementation of the invention enables a single client application on the mobile telephone to automatically configure features on / off, and modify the terminology used in resources (such as menus, text strings, bitmap images, sounds, sonic effects etc.) depending on the external system or service that the client is connected to via the intermediary server.
