  • Patent number: 8975514
    Abstract: Cable assemblies include at least a first wire and a second wire. The wires are enclosed, using injection molding, by a respective layer of thermo-resistant material. During the injection molding, the first wire and second wire are kept substantially straight so as to avoid kinks in at least one of the first wire and the second wire that can develop subsequent to the molding if a wire is not substantially straight. The tension associated with the first wire and the second wire is kept within a predetermined range or below a predetermined threshold. The predetermined range/threshold depends on a temperature associated with the injection molding. The injection molding can provide a zip structure over the wires such that the zip structure can be zipped-together and zipped-apart to prevent entanglement of the wires when used by a user.

  • Publication number: 20150016655
    Abstract: An electrical wire assembly is described that has a first audio electrical wire and a second audio electrical wire. These audio electrical wires can be encapsulated by a thermo-resistant material. The thermo-resistant material encapsulating the first audio electrical wire can encapsulate a ridge, and the thermo-resistant material encapsulating the second audio electrical wire can encapsulate a groove. A slider can be configured to slide along at least a portion of lengths of the first audio electrical wire and the second audio electrical wire to releasably attach the ridge and the groove. A jack can be connected to one end of the audio electrical wires. The jack can be configured to connect to an audio producing device. Earphones or headphones can be connected to the other ends of the first audio electrical wire and the second audio electrical wire. Related methods, systems, apparatuses, and products are also described.

  • Publication number: 20140050349
    Abstract: A zipper assembly is described that includes a first set of electrical wires, a second set of electrical wires, and a first set of zipper teeth. The first set of electrical wires can be encapsulated by a first inner layer made of a thermo-resistant material. The second set of electrical wires can be encapsulated by a second inner layer made of the thermo-resistant material. The first set of zipper teeth can be connected to a zipper tape fabric that is woven with the first inner layer and the second inner layer. The first set of zipper teeth can be configured to be attached to an article of clothing. The first set of zipper teeth can be releasably attached to a second set of zipper teeth attached to the article of clothing. Related methods, systems, apparatuses, and products are also described.

  • Publication number: 20120284258
    Abstract: Methods, systems, and computer program products for searching clinical terminology databases, and more specifically systems and methods for searching structured terminology databases that possess structures for terminology synonyms and semantic parent concept relationships—such as the Systematized Nomenclature of Medicine—Clinical Terms (SNOMED CT) data standard—are provided. This involves interfacing with the database using an application program interface to enable communication between the database and a search module, and searching the database using the search module to generate an ordered list of database records by defining a search string, retrieving database records from the database by matching terms associated with concepts in the database to the search string, and retrieving the database records for the concepts associated with the matched terms. The retrieved results can be ordering based upon a relevancy criterion.

  • Patent number: 6606088
    Abstract: An LCD panel signal processor is disclosed. The LCD panel signal processor of the present invention is applied to an LCD panel having a gate driver and a source driver, and comprises: an input interface for receiving plural types of video signals; a micro-processing device for outputting a first control signal which controls the input interface to select a first type video signal from the plural types of video signals, converting the first type video signal into a digital video signal having an output format, and simultaneously sending an information signal to inform a panel controller of the output format. The panel controller receives the digital video signal according to the output format and generates a gate driver signal and a source driver signal for the gate driver and the source driver.
