Abstract: Embedded Universal Serial Bus (USB) debug (EUD) for multi-interfaced debugging in electronic systems are disclosed. Electronic systems contain complex integrated circuits (ICs) that require extensive testing and debugging to ensure good quality and performance. In exemplary aspects, an EUD is provided in an electronic system. The EUD is configured to send control information to and/or collect debugging information from multiple internal debugging interfaces in the electronic system. The EUD is also configured to convert the debugging information into a USB format so that the debugging information can be externally accessed through a USB interface provided by the electronic system. The EUD can provide non-invasive monitoring of the electronic system. The electronic system is able to use a USB port for communications in a mission mode while EUD is enabled. Additionally, the electronic system can turn on or off all system clocks during power-saving mode while the EUD continues to function.

Abstract: A device and method to accelerate solid metal slugs to high speeds. In one embodiment, a large electric current is passed through an outer cylindrical metal tube enclosing in part a metal slug, a central electrode, and a conducting tail coupled at opposite ends to the. metal slug and the central electrode. Electromagnetic forces accelerate the metal slug to a point high enough to mechanically separate the conducting tail. On separation, a plasma is generated by the passage of electric current though a gas produced by vaporization of the conducting tail and nearby materials. An insulator enclosed within the tube prevents the plasma from shorting to the outer tube until the current flow has produced a sufficient magnetic field to contain the plasma. The metal slug is then accelerated to high speed by a combination of electromagnetic forces and mechanical pressure from the hot gas through which the electric current is passing.

Abstract: Embodiments of the Water Supply Conduit Heating are comprised of a control apparatus and a delivery apparatus. The control apparatus is comprised of two electrically actuated solenoid valves, a pump, a hot water connection, a cold water connection, an electronic control, a temperature sensor, and a double-pipe source connection. The two electrically actuated solenoid valves are controlled by the electronic control. As the temperature of the fluid inbound from the source varies, the electronic control adjusts the mix of hot water and cold water from the hot water connection and the cold water connection to provide an appropriate temperature fluid to the outbound fluid to the source connection. The electronic control is used to measure the temperature of the fluid in the conduit and to direct fluid into the conduit as required to control fluid temperature.

Abstract: A device and method to produce a hot, dense, long-lived plasma. In one embodiment, a large electric current is passed through an outer tube enclosing in part a piston, a notched conducting rod and central electrode. Electromagnetic forces accelerate the piston to a point high enough to mechanically separate the conducting rod at the location of the notch before the conducting rod is melted. On separation, a plasma is generated by the passage of electric current though a gas produced by vaporization of the conducting rod and nearby materials. An insulator enclosed within the tube prevents the plasma from shorting to the outer tube until the current flow has produced a sufficient magnetic field to contain the plasma. The piston is then accelerated by a combination of electromagnetic forces and mechanical pressure from the hot gas through which the electric current is passing.

Abstract: A device and method which combine electromagnetic acceleration with acceleration by high-pressure gases derived from chemical energy to achieve high slug speeds.

Abstract: Solid combustible waste materials are converted into highly efficient fuel by subjecting such materials to size reduction in suitable size-reducing equipment. The last piece of the equipment is a mill which pulverizes the waste materials into fine particles having a high surface to mass ratio and forming a highly efficient fuel when these particles are directly injected into a combustion reactor operating at high temperature.

Abstract: An outsole for a shoe has a backing member of thermoplastic rubber and on an area of the exterior surface of that backing member an intermediate layer of thermoplastic polyurethane and an outermost layer of fabric, the area comprising at least 51 percent of the contact surface of the outsole. In producing the outsole, a sheet of fabric is overlain with a sheet of thermo plastic urethane, the sheet is heated to about the melting point of the TPU to permit the TPU to adhere to the fabric, and the fabric is cooled. The TPU-covered fabric is cut to the size and shape required to fit a backing member, and position in a mold on a bottom surface of a mold, and a quantity of TPR is injected at a temperature lower than the melting point of the TPU but high enough to render the TPU tacky, to insure the inherence of the TPU-covered fabric to the backing, including the resultant outsole.

Abstract: A method for characterizing a threaded coupling such as between two tubular members is disclosed. In one embodiment, a threaded connection between a first tubular and a second tubular is considered, where the first tubular has a internally-threaded box structure and the second tubular has outer threads defining a pin structure. A mathematical model of the connection between the two tubulars is generated, and the mathematical model is permuted to reflect application of at least one flexing force to the joint. From the permuted model, a stress/strain distribution of the box and pin structures is derived. A connection fatigue index value is calculated based on the stress/strain distribution. In one embodiment, connection fatigue indices are computed for a variety of connection combinations, such that a user can compare the relative suitability of multiple box/pin combinations to select one that is deemed desirable for a particular use.
