  • Publication number: 20230282540
    Abstract: A multi-zone substrate for a power stage assembly comprising at least one bottom-cooled semiconductor power switching device and driver components, for integration on a common substrate. A first zone provides electrical connections and a thermal pad for mounting at least one bottom-cooled semiconductor switching device, the first zone comprising dielectric and conductive layers which provide a power substrate optimized for thermal performance. A second zone provides electrical connections for mounting driver components, the second zone comprising dielectric and conductive layers providing a driver substrate optimized for electrical performance. For example, the first zone comprises a single layer metal interconnect structure with a first thermal resistance, the second zone comprises a multi-layer metal interconnect structure with a second thermal resistance, the first thermal resistance being less than the second thermal resistance.

  • Publication number: 20220265333
    Abstract: A bone implant may include a shaft having a proximal end, a distal end, a longitudinal axis, a proximal shaft portion, and a distal shaft portion. The proximal shaft portion may include a first minor diameter, and a first helical thread disposed about the proximal shaft portion defining a first major diameter. The first helical thread may include a first concave undercut surface. The distal shaft portion may include a second minor diameter, and a second helical thread disposed about the distal shaft portion defining a second major diameter. The second helical thread may include a second concave undercut surface. The first and second concave undercut surfaces may be angled towards the distal end of the shaft. The second minor diameter may be smaller than the first minor diameter and the second major diameter may be smaller than the first major diameter.

  • Publication number: 20220201803
    Abstract: A thin film heater is provided containing conductive nanofiller particles and a base material, wherein the conductive nanofiller particles are uniformly distributed within the base material and is soluble in water. When introduced to electric current, the thin film heater raises in temperature and lowers in resistance. A method of manufacturing a thin film heater is also provided, including the steps of mixing the conductive nanofiller particles with water to form a precursor, mixing the precursor with a base material, and applying the mixture to a substrate. Once the thin film heater cures on the substrate, the thin film heater will resistively heat the substrate when introduced to electric current.

  • Publication number: 20170138917
    Abstract: A titration method uses a tracer in the titrant or titrand to quantify the amount of titrant added. The method does not require quantitative addition of titrant or sample. The tracer can be inert or can participate as an indicator of the titrant-analyte reaction. The tracer concentration is quantified by an appropriate method depending upon the type of tracer and analytical performance desired (e.g. precision, accuracy). The method simplifies titrations because it eliminates the need for a precision dispensing device and analytical balance.

  • Patent number: 9562881
    Abstract: A titration method uses a tracer in the titrant or titrand to quantify the amount of titrant added. The method does not require quantitative addition of titrant or sample. The tracer can be inert or can participate as an indicator of the titrant-analyte reaction. If the tracer is inert, an alternative method for monitoring the progress of the titration is required. The tracer concentration is quantified by an appropriate method depending upon the type of tracer and analytical performance desired (e.g. precision, accuracy). The method simplifies titrations because it eliminates the need for a precision dispensing device and analytical balance.

  • Patent number: 7912920
    Abstract: The stream sourcing content delivery system goes to a database and builds a physical stream, based on a schedule. The stream source content delivery system works at a station ID (SID), finds the order of the delivery of content for the station based upon the schedule, and downloads a plurality of music files to its hard drive to enable play back. The stream source content delivery system then concatenates the files, to create stream, and awaits the request of one or more stream recipients. Some preferred system embodiments further comprise a fail-safe mode, whereby a loop of music is generated from the downloaded stream, and is delivered to one or more users when further access to content is interrupted, such that recipients experience an uninterrupted delivery of a plurality of files, e.g. songs.
