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

Patent number: 3959713Abstract: A current limit circuit is disclosed for sensing the current drain of a load connected in series therewith. Under normal operating conditions the circuit presents a relatively low impedance in series with the load. Circuit overload protection is provided if the current increases above a predetermined value by a current limiting circuit provided for limiting the current conducted therethrough. In response to the current limiting condition, thermal shutdown of the circuit occurs to reduce the current that is supplied to the load to a predetermined minimum value i.e., the current limit circuit presents an impedance to the load which is relatively much greater than the impedance of the current limit circuit during normal operating conditions. After a predetermined time, the current limit circuit is again rendered operative and if the circuit overload condition is still present the aforedescribed cycle is repeated until the fault condition is corrected.Type: GrantFiled: March 27, 1975Date of Patent: May 25, 1976Assignee: Motorola, Inc.Inventors: Walter Richard Davis, Tim Warren Henry
