Patent number: 10076442Abstract: The invention relates to systems and methods for controlling vacuum within phacoemulsification systems. The phacoemulsification system may include a handpiece having a needle coupled to a power Source configured to cause the needle to be ultrasonically vibrated during operation, and an aspiration Source. The system includes a footpedal that defines a first position and a second position, and also includes a computer program product operatively coupled to the handpiece and the foot pedal, having a computer usable medium with a sequence of instructions which causes the processor to control power from the power source and vacuum from the aspiration source applied to the handpiece. The process provides a vacuum at a first level to the handpiece when the footpedal is at the first position; provides power to the handpiece when the footpedal is at the second position; and reduces the vacuum to a second level when the footpedal position transitions.Type: GrantFiled: June 16, 2016Date of Patent: September 18, 2018Assignee: Johnson & Johnson Surgical Vision, Inc.Inventors: Wayne S.

Patent number: 9050627Abstract: A method for determining the voltage current phase relationship of a piezoelectric phacoemulsification handpiece generally includes the steps of obtaining an analog AC voltage signal corresponding to the operating AC voltage of a piezoelectric handpiece along with an analog AC current signal corresponding to the operating AC current of the piezoelectric handpiece. Using reference detection circuits, a digital voltage signal and a digital current signal is produced. A synchronous sample clock is taken that has a frequency that is 2N times faster than the frequency of the operating ultrasonic handpiece (i.e., driving frequency), where N is the number of digital bits allocated to the sample clock. This clock measures the time between onsets of a voltage and current cycle. This time value equates to the phase time delta between the two signals. Dividing the synchronous sample clock to obtain the driving frequency ensures the signals are synchronous.Type: GrantFiled: September 2, 2011Date of Patent: June 9, 2015Assignee: Abbott Medical Optics Inc.Inventor: Jon D.

Patent number: 7594448Abstract: Robotic external pipeline crawler system employs the use of logic control to provide a system capable of constantly and accurately maintaining a position at the vertex of the pipe. This apex positioning can be maintained as it traverses the length of the pipe being inspected. This system is adaptable to both straight and curved pipe, multiple pipe diameters, and will substantially reduce set up time and vertical pipeline support crossing time. The crawler system also employs an advanced bracketry system which allows quick disconnecting and auxiliary powered movement allowing for decreased cycle time across pipe supports. The unique tire interface allows for additional surface area contact making extreme environmental conditions possible.Type: GrantFiled: November 8, 2007Date of Patent: September 29, 2009Assignee: Fabtec Solutions, LLCInventors: Dwight W.

Patent number: 6817475Abstract: A system for liquid cleaning a plurality of dirty open-ended cylindrical internal combustion engine paper air filters by subjecting each filter to a cleaning cycle including successive first, intermediate and final cleaning steps. For each step liquid is pumped from a separate tank to spray heads for rinsing a filter at a cleaning station and effluent with entrained contaminants is collected for transfer away from the cleaning station. First step cleaning pumps an unclean liquid previously collected in a first tank as effluent from the intermediate step of a preceding filter cleaning cycle and first step effluent is disposed of away from the system. Intermediate step cleaning pumps a semi-clean liquid previously collected in a second tank as effluent from the final cleaning step of a preceding filter cleaning cycle and intermediate step effluent is collected and transferred as unclean liquid to the first tank for cleaning use during the first stage of the succeeding filter cleaning cycle.Type: GrantFiled: July 29, 2002Date of Patent: November 16, 2004Assignee: Filter Service Corp.Inventors: Jon D.
