Patent number: 9427114Abstract: A magnetic drain stopper for use in a basin drain. A stopper is disposed for reciprocation in the drain pipe and includes a stopper magnet. A curvilinear actuator outside the drain pipe supports one or more driver magnets for movement in a non-linear path toward and away from the stopper magnet. When moved toward the stopper magnet, the driver magnets induce the stopper to lift away from a sealed condition so that water can exit the basin. The curvilinear actuator may include a generally cylindrical base captured in a sleeve-like hinge bracket. A control rod is coupled to a push rod that receives manual input from a user. A pair of flanking legs may be attached to the ends of the base, with each leg carrying a driver magnet half. The curvilinear actuator may include an optional draw-down magnet to hold the stopper in its sealed condition.Type: GrantFiled: June 13, 2012Date of Patent: August 30, 2016Inventor: Henry Tong

Patent number: 8087014Abstract: A method and apparatus for configuration management for a computing device. The apparatus comprises an interface for providing available software to the computing device to be loaded onto the computing device. A processor executes a set of computer instructions to determine whether or not software resident in the computing device is authenticated or not. If the resident software is not authenticated, the processor loads the available software onto the computing device. If the resident software is authenticated, the processor loads the available software only if the available software is also authenticated.Type: GrantFiled: October 26, 2000Date of Patent: December 27, 2011Assignee: QUALCOMM IncorporatedInventors: Dan Vassilovski, Henry Tong

Patent number: 7001262Abstract: A system and method for handling airflow in a paint booth where a primary plenum encloses a secondary plenum having a damper to control the amount of air entering the secondary plenum from the primary plenum. The secondary plenum is installed above a paint spray applicator and an anemometer. A damper at the secondary plenum inlet controls the amount of airflow from the primary plenum in real time based at least in part on the air velocity detected by the anemometer. The present invention can be employed with a system having variable density filter media extending across the primary plenum outlet to regulate the velocities of air moving through various locations of the paint booth.Type: GrantFiled: August 1, 2003Date of Patent: February 21, 2006Assignee: Ford Motor CompanyInventor: Ernest Henry Tong
