Publication number: 20240102484Abstract: A ceiling fan has blades spaced apart circumferentially about and extending outward radially from a rotating component of a motor. The blades include upper blades and lower blades. Each lower blade is between and extends below a pair of adjacent upper blades. The motor, when activated, rotates the rotating component, concurrently rotating the upper blades and the lower blades in the same rotational direction. Each of the upper blades leading an adjacent one of the lower blades is configured to generate and direct an air current rearwardly and downwardly therefrom in front of the adjacent one of the lower blades and each of the lower blades trailing an adjacent one of the upper blades is configured to intercept the air current from the adjacent one of the upper blades and accelerate it rearwardly and downwardly therefrom, when the motor is activated.Type: ApplicationFiled: December 1, 2023Publication date: March 28, 2024Inventors: Joseph Warren Harris, Tim Liu

Patent number: 7968018Abstract: Methods of producing silicone hydrogel ophthalmic lenses include contacting one or more delensed silicone hydrogel ophthalmic lens with a liquid composition that contains alcohol, water, and a surfactant. The methods can be steps of an extraction/hydration procedure used in the production of silicone hydrogel contact lenses. In some examples, contacting silicone hydrogel ophthalmic lens products with a liquid composition that contains alcohol, water, and a surfactant can significantly reduce or prevent surface distortion of the ophthalmic lens resulting from the extraction procedure. Some methods include subsequently contacting the silicone hydrogel ophthalmic lens with a liquid composition consisting essentially of water and a surfactant.Type: GrantFiled: April 18, 2007Date of Patent: June 28, 2011Assignee: CooperVision International Holding Company, LPInventors: Jay Scott Daulton, Charlie Chen, Tim Warren

Patent number: 6804197Abstract: Network probe circuitry is disclosed that is comprised of a host interface system, a line interface system, a memory controller, and a memory. The memory controller receives clock signals from the host interface system and the line interface system. The memory controller grants one of the interface systems access to the memory and selects the clock signal corresponding to that interface system. The memory controller then transfers the selected clock signal to the memory. The interface system with access to the memory communicates with the memory based on the selected clock signal. The memory controller is advantageously faster than prior systems and can handle large data bursts.Type: GrantFiled: October 24, 2000Date of Patent: October 12, 2004Assignee: Agilent Technologies, Inc.Inventors: Tim Warren Henry, Rodney Ray Beeston
