US Patent:

6682463, Jan 27, 2004

Filed:

Jan 2, 2002

Appl. No.:

10/039963

Inventors:

Kenneth Michael Jackson - Phoenix AZ 85022

International Classification:

A63B 6934

US Classification:

482 83

Abstract:

The fluid collection system for ring events comprises a mat, an extraction port and connector, a flexible hose and wet vacuum source. The mat has raised edges to support a sloped surface that gravity feeds the extraction port and raised gasket depressions to support a ring stool. The extraction port has apertures for drainage and is connected to the flexible hose and wet vacuum source by the extraction port connector. This connector fits into at the rear of the extraction port at the 90Â angle of the mat. The mat is hinged to allow it to fold in either direction for rapid deployment and removal. When the mat is deployed, all fluids distributed in the competitors corners will be removed by aide of gravity and the wet vacuum source, leaving the surfaces clean and dry. The fluid collection system promotes safety, hygienic, fair ring event conditions.

Abstract:

A supplementary DC power source is coupled to the DC link circuit of an active power line conditioner (APLC) for sustaining uninterrupted AC power to a load during the time interval needed for AC power restoration or for an alternate or a back-up AC source to be brought on line to power the load upon temporary or continued failure of an AC power source. The supplementary DC source is comprised of a rectifier circuit across which is connected a storage capacitor. A boost converter and an auctioneer diode are coupled between the storage capacitor and the DC link circuit so that when the DC link drops in voltage in response to a sag in the AC source voltage upon loss of the AC voltage source, the necessary power is provided by the storage capacitor and boost converter. A pair of fast acting switches are also coupled between the AC source and the power bus feeding the inverters to isolate the AC source from the APLC and the load upon loss of the AC source. When the back-up AC source is required and comes up to voltage and is synchronized with the APLC, the fast acting switches are again closed to connect the back-up AC source to the APLC and the load.

Abstract:

A magnetometer for magnetic detection includes a magneto-optical defect center material having at least one magneto-optical defect center; a radio frequency (RF) exciter system including a radio frequency (RF) excitation source; an optical excitation system including an optical excitation source; an optical detector configured to receive an optical signal based on light emitted by the magneto-optical defect center material due RF excitation and optical excitation provided to the magneto-optical defect center material via the RF excitation source and the optical excitation source, respectively; a magnetic field generator configured to generate a magnetic field detected at the magneto-optical defect center material; and a system controller.
