摘要:
A game apparatus comprising a playing surface with a plurality of playing members on the surface. A ball member is adapted to move over the playing surface among the playing members with a magnetic element within the ball member. A rotatable surface located below the playing surface carries a plurality of second magnetic elements which exert magnetic forces on the magnetic element within the ball. The movement of the rotatable surface randomly positions the ball member on the playing surface and among the playing members.

摘要:
Remote platform enhanced munitions detection can support improved detection of munitions by separating the signal source platform from a detector on a remote mobile platform. The source platform may support a large, complex, or expensive optical laser or radio frequency source. The source platform may also support a remote signal processing system. The electromagnetic source may be used to illuminate munitions or threat material from a standoff distance. The mobile platform may be maneuvered and positioned closer to the measurement target. The mobile platform may be equipped with an appropriate electromagnetic detector to obtain measurement data at different ranges and positions around the measurement target. The mobile platform may also provide an articulating arm with a mirror or reflector to support non-line-of-sight measurements.

摘要:
The present invention involves a method and an apparatus for analyzing measured signals, including the determination of a measurement of oxygen saturation and respiration rate in the measured signals during a calculation of a physiological parameter of a monitored patient. Use of this invention is described in particular detail with respect to oximetry-based measurements but extends to other types of measurements.
摘要:
An electromagnetic radiation filter uses a plurality of dipole antennas to mitigate the transmission of electromagnetic radiation. The dipole antennas can form one or more arrays that scatter electromagnetic radiation. Examples of application include mitigating the reception of a difference frequency in non-linear radar, use in protective goggles, and use in a protective shield.

Methods are provided for testing a honeycomb body comprised of a core portion comprising honeycomb cell walls and a circumferential skin portion overlying at least some outer honeycomb cell walls. The circumferential skin portion includes a cement mixture layer. The method comprises the step of directing a fluid stream from a pressurized fluid source at the honeycomb body. The fluid stream is capable of separating at least part of the skin portion from the outer honeycomb cell walls when the adherence between at least part of the skin portion and the outer honeycomb cell walls is below a minimum threshold. In one example, the method further comprises the step of inspecting at least part of the interface between the honeycomb body and the skin portion during or after directing the fluid stream at the honeycomb body. In further examples, an apparatus is provided for testing the honeycomb body.
摘要:
A target gas sensing system includes a single source at a first location for generating two light beams having first and second frequencies wherein the difference between the first and second frequencies is the Raman frequency of the target gas. A difference frequency generator outputs the two light beams having the first frequency, the second frequency, and a third light beam having a third frequency that is the difference between the first and second frequencies. The first, second, and third light beams are directed toward the target gas. An input optic directs light from the third light beam, after interacting with the target gas, to a receiver for absorption spectroscopy processing, directs a fourth light beam from the target gas to a receiver for coherent anti-Stokes Raman processing, wherein the fourth light beam has a frequency of twice the first frequency minus the second frequency.
