Publication number: 20240148253Abstract: A catheter device for crossing occlusions includes an elongate body, a central lumen extending within the elongate body from the proximal end to the distal end, a rotatable tip at the distal end of the elongate body, and an OCT imaging sensor. The rotatable tip is configured to rotate relative to the elongate body. The OCT imaging sensor includes an optical fiber coupled with the rotatable tip and configured to rotate therewith. A distal end of the elongate body includes one or more markers configured to occlude the OCT imaging sensor as it rotates. A fixed jog in the elongate body proximal to the distal end of the catheter positions the distal end of the catheter at an angle relative to the region of the catheter proximal to the fixed jog and is aligned with the one or more markers on the elongate body.Type: ApplicationFiled: January 18, 2024Publication date: May 9, 2024Inventors: John B. SIMPSON, Himanshu N. PATEL, Michael ZUNG, Charles W. MCNALL, Priyanshu GUPTA, Maegan K. SPENCER, Christopher B. WHITE, Dennis W. JACKSON, John F. BLACK

Publication number: 20240135388Abstract: A computer executed process for mimicking human dialog, referred to herein as a “humanoid” or “humanoid system,” can be configured to provide automated customer support. The humanoid can identify a support issue for a customer, as well as a customer support campaign corresponding to the support issue. The humanoid can identify at least one machine learning model associated with the customer support campaign and can communicate with the customer using the at least one machine learning model. The humanoid can execute a support action to resolve the support issue.Type: ApplicationFiled: October 29, 2023Publication date: April 25, 2024Inventors: David C. White, JR., Jay K. Johnston, Magnus Mortensen, Christopher Shaun Roberts, Kevin D. McCabe

Patent number: 11300616Abstract: A technique for non-invasively assessing current drawn by a device under test (DUT) by monitoring a supply voltage to the DUT. Frequency data for the DUT may be generated and used to form a current estimation model. First and second voltages are simultaneously measured using first and second test probes electrically connected to the DUT, while the first test probe is connected at a current source, and while the second test probe is connected at a DUT load that is configured to draw current from the current source. The current drawn by the DUT is then assessed by applying the current estimation model to the measured first and second voltages. In one case, the current drawn by the DUT is estimated without insertion of a circuit component into the DUT or extraction of a circuit conductor from the DUT.Type: GrantFiled: July 11, 2018Date of Patent: April 12, 2022Assignee: Mayo Foundation for Medical Education and ResearchInventors: Jonathan L. Fasig, Christopher K. White, Chad M. Smutzer, Michael J. Degerstrom

Patent number: 7957412Abstract: An apparatus comprising a transmission line, a receiver circuit, and a high pass filter circuit coupled between the transmission line and a receiver circuit input. The receiver circuit is configured to receive a data signal over the transmission line at a first data rate. The high pass filter circuit is connected between the transmission line and a receiver circuit input and has a corner frequency that is less than approximately the first data rate and is greater or equal to than approximately one-half the second data rate. The second data rate is an effective data rate caused by an expected data pattern on the transmission line. Other devices, systems, and methods are disclosed.Type: GrantFiled: March 19, 2008Date of Patent: June 7, 2011Assignee: Cray Inc.Inventors: Michael Steinberger, Ricky J. Hakes, Christopher K. White

Patent number: 7787766Abstract: An apparatus and method is provided for sensing which faults have occurred in a laser control system, as well as trapping and identifying the first fault occurrence. The apparatus includes an integrated circuit in which a mask register is set by means of a micro-controller or a host system to select which fault sources are to be recorded. A status bit register in which the fault indications are stored can also be interrogated by the micro-controller or a host system. A settable first fault status register determines whether every fault or only the first fault gets recorded.Type: GrantFiled: November 28, 2006Date of Patent: August 31, 2010Assignee: JDS Uniphase CorporationInventors: Stephen J. Ames, Steven J. Baumgartner, Christopher K. White

Patent number: 6661817Abstract: An apparatus, program product and method enable a host system to read a signal or signals that are proportional to the output power and/or the bias of a laser in a fiber optic link connected to that host system without breaking that link. By reading one or more of these signals and being aware of the laser characteristics, the “health” of the laser is known and the integrity of the link is maintained. Consequently, the host system has a predictive tool which is able identify substandard lasers and replace them before a serious, and potentially costly, data disruption occurs.Type: GrantFiled: September 18, 2001Date of Patent: December 9, 2003Assignee: International Business Machines CorporationInventors: Stephen John Ames, Michael William Marlowe, Christopher K.

Patent number: 6627867Abstract: An apparatus, circuit arrangement and method enable a host system to read a signal that is proportional to the peak-to-peak optical power incident on a transceiver at one end of a fiber optic link without breaking that link. By reading this signal and being aware of the characteristics of the laser, the “health” of the laser is known and the integrity of the link is maintained. Consequently, the host system has a predictive tool that is able identify substandard lasers so that such lasers can be replaced before serious, and potentially costly, data disruptions occur.Type: GrantFiled: November 20, 2001Date of Patent: September 30, 2003Assignee: International Business Machines CorporationInventors: Stephen John Ames, Michael William Marlowe, Christopher K.
