Methods and apparatus for stereoscopic image encoding and decoding are described. Left and right eye images are encoded following an entropy reduction operation being applied to one of the eye images when there is a difference between the left and right images of an image pair. Information about regions of negative parallax within the entropy reduced image of an image pair is encoded along with the images. Upon decoding a sharpening filter is applied to the image in an image pair which was subjected to the entropy reduction operation. In addition edge enhancement filtering is performed on the regions of the recovered entropy reduced image which are identified in the encoded image data as regions of negative parallax. Interleaving of left and right eye images at the input of the encoder combined with entropy reduction allows for efficient encoding, storage, and transmission of 3D images.

A holographic recording medium having a polymer matrix comprising a developer, wherein the holographic recording medium is capable of recording a latent hologram and the developer is capable of developing the latent hologram into a readable hologram by activation of the developer is disclosed. The holographic recording medium is capable of storing large numbers of holograms in the same volume with better signal resolution than previous holographic media by first recording a multitude of latent (or very weak) holograms in the same volume of space, then applying preferably a non-chemical fixing step to develop the latent holograms into readable holograms. The holographic recording medium and method of this invention cause the holograms to increase in diffraction efficiency, thus preventing complications caused during recording of holograms whereby previously recorded holograms interfere with latter recorded holograms in the same volume of space within the media.

The present invention relates to embodiments of a process for subjecting a holographic storage medium to illuminative treatment to: (1) enhance or optimize recording of holographic data; (2) enhance or optimize reading of recorded holographic data; and/or (3) erase recorded holographic data. The present invention also relates to embodiments of a system comprising: (a) an illuminative treatment beam; (b) means for reducing the coherence of the beam and (c) means for transmitting the reduced coherence beam to cause illuminative treatment of: (1) an unrecorded portion of a holographic storage medium to provide pre-cured portions having increased ability to stably record holographic data; (2) a recorded portion of a holographic storage medium to provide a post-cured portion having reduced residual sensitivity; and/or (3) a recorded portion of a holographic storage medium having holographic data to provide an erased portion wherein at least some of the recorded holographic data is erased.

An apparatus for evaporating liquid samples contained in sample holders mounted within a chamber and by rotated by the rotor during an evaporation process in which the pressure in the chamber is reduced below atmospheric and the sample holders are rotated at high speed so as to exert centrifugal force on the contents of the holders. Heat is supplied to elevate the temperature of the liquid component of the samples to assist in the evaporation process. The temperature of the sample material is continuously or regularly monitored during the evaporation process and temperature signals are transmitted to a remote computing means which is programmed to generate a control signal for controlling the supply of heat to the samples and controlling the evaporation process. The temperature may be sensed by a probe in a sample holder containing an evaporating liquid sample, or in an adjoining sample holder containing a buffer liquid. The rotational speed is also sensed and a speed signal conveyed to the computing means.

A method is described for evaporating liquid samples contained in sample holders mounted within a chamber and rotated by the rotor during an evaporation process in which the pressure in the chamber is reduced below atmospheric and the sample holders are rotated at high speed so as to exert centrifugal force on the contents of the holders. Heat is supplied to elevate the temperature of the liquid component of the samples to assist in the evaporation process. The temperature of the sample material is continuously or regularly monitored during the evaporation process and temperature signals are transmitted to a remote computing means which is programmed to generate a control signal for controlling the supply of heat to the samples and controlling the evaporation process. The temperature may be sensed by a probe in a sample holder containing an evaporating liquid sample, or in an adjoining sample holder containing a buffer liquid. The rotational speed is also sensed and a speed signal conveyed to the computing means. In an alternative method the rate of flow of vapor from the chamber is monitored and a flow rate signal is computed which is also supplied to the computer means and the evaporation process is controlled in relation to the value of the vapor flow rate signal. Improved methods of heating and means for supporting sample holders which are to be heated, to achieve more uniform heating thereof, within an evaporating chamber, are described. Apparatus for performing the various methods is also described.
摘要:
A reduction of sample loss from a container open to atmosphere, and including liquid trifluoroacetic acid (TFA), is carried out by a variety of methods each of which reduces creep of TFA up the walls of the container. In one method, particularly applicable to microtitre plates, each container or well is sealed by a cap which is retained by a strap (FIGS. 4 and 5). In another method the top of the container is formed with a downwardly pointing entrance tube, in the form of an unspillable inkwell (FIG. 2), where the container is a screw top vial, the entrance tube is sealed around the top of the neck of the vial (FIG. 9b).

A knee prosthesis kit includes an implant and an augment. The implant has a base and a stem extending from the base, and the augment has a base and a conical, cylindrical, or anatomic portion extending from the base. The augment base has at least two openings for receiving fasteners for securing the knee augment to the implant. The portion and the base define a bore for receipt of the implant post. A coupler includes a mating portion for receipt in a bore of an implant post, and a cone-shaped portion extending from the mating portion. A method of providing fixation of knee implants includes securing an augment to an implant and positioning a conical, cylindrical, or anatomic portion of the augment within the intramedullary canal of the tibia or femur.
摘要:
The present invention generally relates to a mechanical ball joint assembly which is particularly useful in finishing tools. The finishing tools may be used, for example, to prepare drywall surfaces for decorating and/or painting. The mechanical ball joint assembly may allow a body casting of the finishing tool to rotate in almost any direction with respect to ball joint and handle portion of the finishing tool. As a result, the body casting may be used to perform work on the drywall at many different angles, including ninety degree angles at the corners of most rooms. An opening in the ball joint assembly of the finishing tool may secure a ball joint portion by, for example, a moveable securing rod having an indentation. The movable securing rod of the ball joint assembly may allow the user to temporarily secure the ball joint within the opening of the ball joint assembly. The movable securing rod is spring-loaded to secure the ball joint within the opening of the ball joint assembly. The ball joint may be removed from the opening of the ball joint assembly to, for example, clean, replace, repair, store or transport the finishing tool.
