Abstract: Disclosed are a computing device bezel and a facia button that is used with the bezel. In one embodiment, the facia button includes a base member, a finger interface that is supported by and that extends from the base member, an axis about which the facia button can pivot, and a spring member that is adapted to resist pivoting of the facia button, wherein the facia button is configured to contact and press an associated button of a device contained within the computing device.

Abstract: Apparatus and method for catheterized delivery or infusion of medication and anaesthesia are disclosed. The perforating catheter is first used to perforate the periodontal ligament and/or the cortical plate of bone tissue, and is then left in place and used as a catheter for insertion of a hypodermic needle of smaller gauge to deliver medication or anaesthesia to a target area. The perforator is a bevelled needle for drilling into the ligament or bone tissue. For drilling, the device comprises an adaptor which transmits the rotational movement from a dental hand piece or the like to the bevelled needle. A cap is also included for protecting the bevelled needle during storage of the device. The adaptor may have a rod which extends axially into the bevelled needle when the device is assembled for drilling. The rod is used to prevent the debris resulting from drilling from blocking the passage in the bevelled needle.

Abstract: A system and method for the use of ultra high frequency RFID tags in conjunction with metal substrates, as well as substrates used to contain liquid. Briefly, an RFID isolator comprised of a material with complex magnetic permeability, used either by itself, or in combination with dielectric isolator material, is interposed between the RFID tag and the substrate. Alternatively, a material possessing at least two distinct dielectric constants is interposed between the RFID tag and the substrate, such that there is a high dielectric constant at the interface with the substrate, and a low dielectric constant at the interface with the RFID tag. This material can be a single material having a dielectric constant gradient, or alternatively, two or more separate layers, each with a uniform but different dielectric constant, sandwiched together.

Abstract: Incorporation in a laundry detergent composition of a graft polymer having a locust bean gum backbone and grafts of an aromatic sulphonic acid improves antiredeposition properties. The preferred polymer is locust bean gum—graft—poly (4-styrenesulphonic acid).

Abstract: The present invention provides a system and method for optimizing the performance of 13.56 MHz frequency RFID tags in conjunction with metal substrates. Briefly, a thickness exists for each type of RFID isolator material at which the performance of a 13.56 MHz RFID tag is optimal when used with metal. Varying from this optimal value, in either the positive or negative direction adversely affects read distance. A method of determining this optimal thickness is disclosed, as well as an RFID tag or a substrate being used in conjunction with a material of this thickness.

Abstract: A system and method for tracking ocular changes during a surgical procedure include directing an eye-safe optical beam toward an undilated, unparalyzed eye. A reflected optical beam is detected, and measurements are performed based upon data contained in the reflected optical beam of at least one geometric parameter of the eye at a predetermined frequency, and from them is calculated a change in the at least one geometric parameter. The calculated change is used to dynamically adjust the directing of laser beam shots during the surgery.

Abstract: In one embodiment, a computer system includes a first component configured to output data on a bus in response to a request for data from a second component. The data output by the first component may include both the requested data and unrequested data, and the unrequested data may have an unpredictable value. A controller coupled to the bus may be configured to replace the unrequested data with data that has a predictable value. A signature analysis register included in the second component is configured to capture the requested data and the predictable data output by the controller. Thus, the signature captured in the second component may be predictable, despite the unpredictable data output by the first component.

Abstract: A microbiological testing method or assay for identifying an organism grown on one chromagenic semisolid nutrient media such as agar, where the organism exhibits at least one color or chromatic aspect. A digitized electrical signal is generated encoding an image of the organism on the nutrient media. The encoded image is stored and digitally processed to detect the color of the organism on the nutrient media. Chromatic characteristics of a multiplicity of known organisms are stored in an electronic library. A computer is operated to compare the detected color of the organism with chromatic characteristics stored in the library.

Abstract: A method for gene shuffling to form a mutant or chimeric gene, the method comprising: (a) assigning one or more segments of one or more genes based on regions of encoded amino acid sequence; (b) amplifying the one or more assigned segments of the gene using primers specific for each segment; and (c) causing recombination of the one or more amplified segments to form a mutant or chimeric gene. An oligonucleotide primer suitable for use in gene shuffling, the primer having a non-degenerate core based on a segment or template of a gene to be amplified, and the core being flanked by both 5′ and 3′ degenerate ends.

Abstract: A portable dental system and method is disclosed for cleaning endodontic files and the like during a operation such as a root canal procedure. This allows a dentist to clean files in situ while performing the removal of root material. As the file is withdrawn from the patients mouth by the dentist, it can be inserted into a sealed container through the lid and can be cleaned ultrasonically and immediately withdrawn and reinserted into a patients tooth canal for further removal of tooth and root material. Debridement of the files ensures less likelihood the file will break within the canal; furthermore, since no passing off to or cleaning the tip by an assistant is required, there is less likelihood of inadvertent skin puncturing and infection of the dentist or assistant. The sealed disposable container housing a cleaning fluid is insertably removable from the base, which supports it and provides a source of ultrasonic energy thereto.

The lens also includes an outer shell layer comprising a cured or fused substantially homogenous blend of hollow glass spheres and curable or fusible resin. The outer shell layer preferably has a dielectric constant of about 1.0, and an interstitial void volume of from about 30% to about 50%. In addition, the lens includes a minimum of one, and preferably two or more intermediate layers, the intermediate layers having a dielectric constant falling between 1 and 2.
