Abstract: A dental wedge for use in the inter-proximal space between adjacent teeth. The wedge includes a taper section ending at a tip, and a body section extending to the tapering section at one end. The body section has an inverted V-shaped cross-section, flexing of the sides of the V-shape allowing the wedge to adapt to various contours of the inter-proximal space. The mid-portion of the body section is narrower than at least a portion of the wedge at either end of the mid-portion.

Abstract: The present invention provides a complete artificial intelligence system for the acquisition and analysis of nucleic acid array hybridization information. The system includes a central data processing facility and one or more user facilities, linked by encrypted connections. Each user facility may include an optical scanning system to collect hybridization signals from a nucleic acid array, an image processing system to convert the optical data into a set of hybridization parameters, a connection to a data network, and a user interface to display, manipulate, search, and analyze hybridization information. This system reads data from a nucleic acid microarray, analyzes test results, evaluates patient risk for various ailments, and recommends methods of treatment. The automated artificial intelligence system is a real time, dynamic decision making tool that can be used in conjunction with a clinical analysis system, and with the information obtained in a research and development environment.

Abstract: Methods are presented for isolating and purifying proteins by adding a polyelectrolyte to a cell culture fluid, such as a harvested cell culture fluid, and precipitating a protein-polyelectrolyte complex or a complex of impurities and the polyelectrolyte.

Abstract: The present invention relates to dental crowns for use in restoring a prepared tooth wherein the dental crown comprises a universally sized crown shell and crown matrix to enable the sizing and fitting of the dental crown to the patient in a single sitting and without an impression or laboratory procedure.

Abstract: A manufactured device for handling a dental restoration, the device comprising an adhesive receiving surface and handle adjacent thereto for grasping of the device by a dental hand tool such as a tweezer or forceps. The handle may also include a bore configured to receive the pins ends of the pin tweezer for grasping the device. The adhesive receiving surface is configured with varying dimensions and shapes to correspond to the different restorations. The adhesive receiving surface may also include lug portions for controlling the amount of adhesive to the device.

Abstract: A method of fabricating a photodiode detector array is provided. The method facilitates a reduction in secondary photon emission detection by the photodiode detector array. The method includes fabricating an array of active regions, wherein the array of active regions comprises a plurality of active regions. The method also includes positioning a passivation region in optical paths between the active regions. The passivation region includes at least one of a photon-absorbing material and a trench.

Abstract: Techniques to modify a document using a latent transfer surface are described. An apparatus may comprise a document editing subsystem comprising a transfer surface creation module operative to embed a latent transfer surface in the document. A transfer control module may be communicatively coupled to the transfer surface creation module. The transfer control module may be operative to receive a transfer request to transfer media content for the document, and transfer the media content using the latent transfer surface in response to the transfer request. Other embodiments are described and claimed.

Abstract: A device (10) for concurrently depositing different semi-solid products (12, 14) and 16 in a container (18) in respective vertically-oriented, distinct, homogeneous masses includes first and second inlet ports (24) and (26) provided at an upper end of a main filler tube (20) and first and second filler tube outlet ports disposed in a nozzle-form outlet opening (52) at a lower distal end of the main filler tube (20). A dividing insert is carried within the main filler tube (20) in a generally vertical orientation in a position separating the tube (20) into first and second channels. The first and second channels provide fluid communication between the first inlet port (24) and the first outlet port and between the second inlet port (26) and the second outlet port.

Abstract: An apparatus for controlling a radio bearer reconfiguration in a cellular communication system, such as a UMTS communication system, comprises a reconfiguration instigator (301) which initiates a radio bearer reconfiguration for a radio bearer supporting a communication between a base station (105) and a user equipment (107). Rather than using a static worst case estimate, a reconfiguration switch time processor (309) determines a reconfiguration switch time in response to a dynamic parameter of the radio bearer reconfiguration process. In particular, the radio parameter may be a size of a radio bearer configuration message transmitted to the user equipment (107). The reconfiguration switch time is transmitted to the base station by a base station communication processor (311) and to the user equipment (107) by a UE communication processor (313). The base station (105) and the user equipment (107) reconfigure their circuitry to apply the reconfigured parameters from the reconfiguration switch time.

Abstract: Methods are presented for isolating and purifying proteins by adding a polyelectrolyte to a cell culture fluid, such as a harvested cell culture fluid, and precipitating a protein-polyelectrolyte complex or a complex of impurities and the polyelectrolyte.

Abstract: It is a motor which runs on Prepetual Motion.

Abstract: A matrix band retainer for dental restoration has a unitary member of a stiff planar spring material. The unitary member has an open ring substantially in a first plane, with the plane of the material of the ring perpendicular to the first plane. A tine at each end of the open ring extends substantially normal to the plane of the ring. Each tine has a first planar portion extending from the ring and a second planar portion extending from the first planar portion. The second planar portion is at an angle to the first planar portion and adjoins the first planar portion to define a ridge. The ridges of each tine face each other across a gap. Each tine may be bifurcated at the end distal from the ring so that the distal portion of each of the first planar portion and the second planar portion are divided by a notch. A dental wedge can be inserted through the notch with the matrix band retainer in place.

Abstract: An air cleaner that includes a first housing portion having a non-circular attachment fit. A second housing portion is attached to the first housing portion to define a filter space. A filter element includes a non-circular filter aperture that defines a perimeter that is completely defined by four equal arc length segments. The filter aperture is engageable with the attachment fit. The attachment fit and the filter aperture are sized to provide substantially equal contact pressure around the perimeter of the filter aperture when engaged with one another.

Abstract: A dental contact matrix system is described for the placement of dental fillings. The dental contact matrix system includes a matrix, a retainer for placing and retaining the 5 matrix and an elastic wedge. The retainer includes two lugs or tines that fit between two teeth on the buccal and lingual sides of the teeth. The lugs are connected by spring member that presses the lugs against the lingual and buccal sides of the teeth. There is an adaptation to hold the elastic wedge in a stretched condition between the lugs.
