摘要: A flywheel system suitable for storing energy when demand for energy from a power plant is low, and from which energy can be retrieved when energy demand increases. The flywheel includes (a) a circular composite or metallic glass ring with a radial width limited to less than about 30 percent of the ring's outer radius, and (b) at least one spoke extending along a diameter of the ring, and attached to the ring at either end. The spoke has sufficient radial extendability due to either bending and elastic radial elongation, or only elastic elongation so that, when the flywheel rotates at operating speed, the spoke extends radially to match the radial growth of the ring, without subjecting the flywheel to significant tension at points of attachment of the spoke to the ring. In one embodiment, both flywheel ring and spoke are made of oriented high strength fibers embedded in a thermoplastic resin. Also provided are a magnetic bearing and motor/generator system that are of an axial-gap design so that magnets are held in a substantially fixed position relative to each other, as the flywheel expands radially under centrifugal forces. Further, both motor/generator and flywheel bearings utilize a system of permanent magnets alternating with a high magnetic permeability composition in order to produce highly uniform magnetic fields in the bearing to reduce magnetic drag and improve efficiency, and to produce high torque in the motor generator. The flywheel bearing assembly includes a bulk high temperature superconductive magnet that provides lateral stability to the flywheel.

摘要: An electromagnetic interference (EMI) and/or electromagnetic radiation shield is formed by forming a conductive layer (42, 64) over a mold encapsulant (35, 62). The conductive layer (42, 64) may be electrically coupled using a wire to the leadframe (10, 52) of the semiconductor package (2, 50). The electrical coupling can be performed by wire bonding two device portions (2, 4, 6, 8) of a leadframe (10) together and then cutting the wire bond (32) by forming a groove (40) in the overlying mold encapsulant (35) to form two wires (33). The conductive layer (42) is then electrically coupled to each of the two wires (33). In another embodiment, a looped wire bond (61) is formed on top of a semiconductor die (57). After mold encapsulation, portions of the mold encapsulant (62) are removed to expose portions of the looped wire bond (61). The conductive layer (64) is then formed over the mold encapsulant (62) and the exposed portion of the looped wire bond (61) so that the conductive layer (64) is electrically coupled to the looped wire bond (61).

摘要: A thumb protector for protecting the thumb of a user from calluses and inflamed skin from repetitive use of computer game controllers. The thumb protector includes a sleeve that is adapted to cover a distal end of the digit of the user. The sleeve has an upper portion and a lower portion; the upper portion is adapted to cover a top of the distal end of the digit and the lower portion is adapted to cover a digital pulp of the digit of the user. A plurality of ridges outwardly extend from the lower portion of the sleeve such that the plurality of ridges are adapted for increasing traction between the sleeve and the game controller when the sleeve is covering the distal end of the digit.

摘要: A gas fed catalytic heater is employed as a heat source in the thermoforming of shaped articles from a sheet of thermoplastic material. The thermoplastic sheet is fed from a continuous supply roll past an array of gas catalytic heaters in a heating section in order to soften the sheet prior to entering a mold for shaping the articles. A closed loop temperature control system is provided for controlling the pressure and hence the volume of gas entering the catalytic heaters and thus the emitted infrared radiation to automatically maintain the temperature of the thermoplastic sheet at a predetermined set value. The control system includes a temperature sensor for measuring the temperature of the sheet, a temperature controller for comparing the actual temperature of the sheet against a preset temperature and for producing an output signal that is proportional to the difference temperature and a gas modulating valve which is responsive to the output signal for adjusting the flow of gas to the catalytic heaters.

摘要: The invention is directed to a method for discrete-event simulation, using dynamic memory in a parallel environment under Cautious Optimistic Control (COC). The method is divided into three sub-processes. The first is the pre-processing phase, which prepares the simulation for event execution. The second is the execution phase, which prepares the simulation for event execution. The third is the post-processing phase, which handles the cleanup of the simulation after the end of event execution. The invention can be integrated into various software architectures for run-time use or in post-processing analysis for data analysis in test and evaluation environments.
