Title: Method and apparatus for determining the resonant frequency of a resonant circuit
Inventor: BUSSE OLAF
IPC: G01R23/07
Filed: 2004-03-01
Abstract: The invention intends to improve the determination of the resonant frequency of a resonant circuit, in particular of a heating circuit for a discharge lamp.      For this purpose, the frequency of a supply voltage for the resonant circuit is varied within a predetermined frequency range. The voltage or the current across/in the resonant circuit are measured as a function of the varied frequency. The predetermined frequency range is run through in both directions, in each case a maximum for the measured voltage or the measured current being established. The resonant frequency is preferably calculated from the two maxima by averaging.

Patent CA-2461849-A1 (CA)
Title: Roll-over valve
Inventor: GRAF MANFRED
IPC: F16K17/36
Filed: 2004-03-23
Abstract: A roll-over valve for a blow-by gas circulation system of an engine includes a piston slidably mounted within a valve housing. A lateral inlet opening and an outlet opening are disposed in the valve housing. When the valve is upright, fluid flows freely from the inlet opening to the outlet opening through the valve housing. When the valve overturns, the piston moves axially within the valve housing under the force of gravity into a roll-over position. When the piston is in the roll-over position, it blocks the fluid path between the inlet and outlet lines to close the valve. The inlet opening is positioned such that pressure in the inlet opening does not impede the movement of the piston. An air bleed passage fluidly connects portions of the valve housing that are above and below the piston and dampens movement of the piston within the valve housing.

Title: Contour adaptable, launderable, waterproof mat to provide an essentially level, horizontal surface on which to change diapers in vehicles
Inventor: HAEBERLE PAULA M
IPC: B60N3/00
Filed: 2005-02-22
Abstract: This invention provides an essentially level surface upon which to change an infant's diaper, by means of incorporating a top changing surface with a malleable pillow that forms to the contours of a vehicle seat. The diaper changing mat (hereafter referred to as the Seat PAL Change Mat), itself, consists of multiple pieces: a top mat (the changing surface), a closable pocket affixed to the bottom of the pad, and a malleable pillow to fit inside the affixed pocket. The top layer, which the infant is laid upon during a diaper change, provides ample coverage of a vehicle seat during the diaper-changing process. It extends beyond the edges of the affixed pocket, with it's enclosed malleable pillow, and provides a soft, yet waterproof surface. The pillow is stuffed with a small-particle, pellet-like, malleable substance to allow easy forming into the contours of the vehicle seat. It is contained in a closable pocket, on the underside of the mat, to provide a single unit for use in vehicle seats.      With the pillow removed, the change pad is launderable, allowing for easy clean-up of any soiling that may occur during the diaper changing process. Using a malleable pillow combined with the top pad, allows the contours of a vehicle seat to be minimized, rendering the surface essentially level.
