摘要:
A tabletop game for head-to-head competition including a platform having a curved path. The game includes a plurality of knock-down objects configured to be knocked down by a ball. The ball includes a weighting that is off center from a geometric center of the ball causing the ball to roll in a non-linear path.

An amusement device used to move a supported display object through an erratic path. The amusement device includes a base element in which is disposed a rotating assembly. The rotating assembly can be battery powered, spring powered or manually powered. A support spring is used to interconnect a display object to the rotating assembly in the base element. The support spring has a first end and a second end. The first end of the support spring is coupled to the rotating assembly within the base element, wherein the support spring is rotated by the rotating assembly. The remainder of the support spring extends freely from the base element. The display object is coupled to the second end of the support spring. As the display object rotates, it causes the support spring to at least partially elongate, thereby causing the display object to move erratically from point to point.

A mass spectometer for analyzing a beam of ions generated from a sample of analyze comprises an analyzer (3) and an interface between the analyze sample (1) and the analyzer. The inlet aperture to the analyzer (13) is positioned off the axis of the ion beam (2) exiting the interface system, and a deflector is (14) provided to generate an electric field between the interface system and the analyzer to deflect the ion beam into the inlet aperture of the analyzer.

This invention enables high temperature superconducting (HTS) metal oxide materials ReBa2Cu3Ox ((RE)BCO) to carry high superconducting currents at high current densities under high magnetic field (≧3 Tesla), in all orientations of the field, and at high temperatures (65 Kelvin). The superconductor is adapted to carry current in a superconducting state, with the superconductor having a current (I) carrying capacity of at least 250 A/cm width, in a field of 3 Tesla (T), at 65 Kelvin (K), at all angles relative to the coated conductor. More preferably, the current carrying capacity extends through the range of substantially 250 A/cm to 500 A/cm. Excellent performance is achieved by use of intrinsic pinning centers in the HTS compound. The invention preferably does not require the addition of extra elements or compounds or particles to the superconducting compound during synthesis, nor does it require extra process steps.
摘要:
Electric vehicle charging methods, battery charging methods, electric vehicle charging systems, energy device control apparatuses, and electric vehicles are described. In one arrangement, an electric vehicle charging method includes receiving information regarding charging of an electric vehicle with energy from an electric power grid, determining an amount of energy stored by an energy storage device coupled to the electric power grid, and controlling a transfer of the energy stored by the energy storage device to the electric power grid using the information regarding the charging of the electric vehicle. Other arrangements are described.

A stringer assembly for mounting to steps of a stairway, comprises first and second stringer members. The first stringer member are adapted to be secured to the steps with first fasteners that are driven through the first stringer member and then into the steps. The second stringer member is adapted to be positioned with respect to the first stringer member such as to conceal the first fastener and to be mounted thereto via second fasteners and glue, wherein the second fasteners are adapted to be driven through the first stringer member and then into the second stringer member. Decorative covers are provided for mounting onto exposed edges of the first and second stringer members. A method for assembling a stringer to steps of a stairway and a kit for producing a stringer assembly for use in stairways are also disclosed.
摘要:
An ion detector includes an entrance aperture for receiving ions, a Faraday cup, an electron multiplier, and an ion beam controller arranged to direct ions received through the entrance aperture. The controller is switchable between a first configuration in which the controller acts such that received ions are detected by the Faraday cup, and a second configuration in which the controller acts such that received ions are detected by the electron multiplier.
