Publication number: 20230310810Abstract: A platform configured to secure a service loop of tubing from a fixed position surgical device. The platform allows for avoidance of taping and re-taping of service loops. Additionally, the platform provides stability to the surgical device so as to avoid unintentional changing of position or orientation of the device. This is of particular benefit for an infusion port during eye surgery and other similar devices where orientation of the installed device aids device performance.Type: ApplicationFiled: March 27, 2023Publication date: October 5, 2023Inventors: James Y. Chon, Joel Cicchella, Robert Jeffrey Heng, Grace Chuang Liao, Ashish Sinha

Patent number: 8631831Abstract: In various embodiments, aspiration tubing connecting a handpiece to a surgical console may include a high compliant section, a transition section, and a low compliant section. In some embodiments, the high compliant section may have a lower durometer and/or different geometry than the low compliant section. The transition section may take a number of forms, including a connector or a continuous section of tubing that gradually increases in durometer and/or changes geometry through the length of the tubing. In the various embodiments, the high compliant section may provide flexibility near the handpiece to make the handpiece easier to hold and maneuver while the low compliant section may reduce the effects of occlusion break surge. In some embodiments, the high compliant section may include, for example, ribs, stiffening rings, a stiffening sleeve, or a stiffening sock to increase the stiffness of the high compliant section.Type: GrantFiled: August 12, 2009Date of Patent: January 21, 2014Assignee: Alcon Research, Ltd.Inventors: Ramon Carsola Dimalanta, Jr., Grace Chuang Liao, Robert Harry Peterson

Patent number: 7983362Abstract: Receiver architectures and bias circuits for a data processor are provided. A receiver architecture includes a linear receiver having a first input node for a data (DQ) signal, a second input node for a reference voltage, and output nodes for a differential output signal. The linear receiver compares the DQ signal to the reference voltage, and generates the differential output signal in response to the comparison. A sense amplifier is coupled to the linear receiver. The sense amplifier has input nodes connected to the output nodes of the linear receiver, and an output node for a binary output signal having voltage characteristics compatible with the processor. The sense amplifier transforms the differential output signal into the binary output signal. The receiver architecture also includes a programming architecture coupled to the linear receiver to set operating characteristics of the linear receiver.Type: GrantFiled: April 10, 2008Date of Patent: July 19, 2011Assignee: GLOBALFOUNDRIES, Inc.Inventors: Shawn Searles, Grace Chuang, Christopher M.
