摘要： A universal and height adjustable drain adaptor and methods of manufacture can include: a bonding flange; and a collapsible base coupled to the bonding flange, the collapsible base including folds and a bottom portion, the collapsible base configured to collapse about the folds to provide an extended configuration and a collapsed configuration, the extended configuration includes the bonding flange being further from the bottom portion than the collapsed configuration, and the bonding flange and the collapsible base create a universal drain adaptor with the bottom portion configured to be clamped between a drain base and a clamping ring.

摘要： A proximity detection system for determining when a single channel receiver becomes proximate to any point on a wireless closed boundary continuously generated by a transmitter. The transmitter includes a magnetic field generator broadcasting a composite, modulated, time-varying magnetic field signal of a particular carrier frequency. The receiver forms a measure of the broadcast magnetic field intensity incident to the location of the receiver or a measure of the power or energy of incident field.
