Publication number: 20240129426Abstract: A camera system and method provide a trailing motion blur effect without the use of a flash. In one embodiment, a variable light-transmissive filter is positioned in front of an image sensor. While the light-transmissive property of the filter is lower, the blurred image of the object in motion is produced. The light-transmissive property of the filter is increased during the exposure in order to produce a clearer image of the object. In a method, a plurality of images taken in rapid succession are combined to produce a clear image of the object with a trailing blurred image of the object.Type: ApplicationFiled: June 1, 2023Publication date: April 18, 2024Inventors: Kyle L. Baltz, John E. Carlson

Publication number: 20240116133Abstract: Systems and methods determine alignment between a wire and a laser beam in laser joining. A system for checking alignment of a wire relative to a beam of a laser includes a controller configured to align, by tooling, the beam with a sensor system. A laser generates the beam across the wire, with the beam directed to the sensor system. The sensor system measures light intensity of the beam. A processor computes a feature parameter representative of an alignment between the wire and the beam. The processor determines whether the feature parameter is within the process specifications.Type: ApplicationFiled: October 11, 2022Publication date: April 11, 2024Inventors: Junjie Ma, John Forrest, William A.

Publication number: 20240106700Abstract: The present disclosure generally relates to methods for sending event notifications. In some examples, a controller periodically sends messages concerning a status of an event corresponding to the controller. In some examples, at a first time while periodically sending the messages and in accordance with a determination that the status of the event has changed, the controller sends a message concerning data other than the status of the event. In some examples, at the first time while periodically sending the messages and in accordance with a determination that the status of the event has not changed, the controller continues to periodically send the messages without sending the message concerning data other than the status of the event.Type: ApplicationFiled: June 23, 2023Publication date: March 28, 2024Inventors: Ramy R. ASSELIN, John A. WILKEY, Jamie P. CARLSON, Stephanie L. LEGAULT, Abdul Rahman AL-SHAWA, Anil K. KANDANGATH, George E. WILLIAMS, Jangwon LEE, James D. BATSON, Fabien GONCALVES

Patent number: 9772353Abstract: Aspects of the invention include an equivalent-time sampling oscilloscope that receives a carrier signal, the carrier signal after it has been modulated with a repeating data pattern, and a pattern trigger signal that is synchronous with the data pattern. The carrier signal and the modulation are asynchronous, that is, they are not phase-locked in any way. The oscilloscope simultaneously samples the modulated carrier signal and quadrature phases of the unmodulated carrier signal at a plurality of timebase delays relative to the pattern trigger signal, and a plurality of times at each timebase delay. After collecting this information, the oscilloscope uses the quadrature samples to calculate phases of the unmodulated carrier signal that correspond to the samples of the modulated carrier signal.Type: GrantFiled: October 4, 2013Date of Patent: September 26, 2017Assignee: Tektronix, Inc.Inventors: Michael A.

Patent number: 9093955Abstract: Waveforms generators include a splitter that splits a digital input signal into a number of split signals each having a split signal frequency bandwidth that is substantially similar to a digital input signal frequency bandwidth. The split signals are mixed with associated digital, harmonic signals to generate a number of digital, mixed signals, which are then converted to analog signals at an effective sample rate that is different from a first order harmonic signal of at least one of the digital, harmonic mixers. A number of analog, harmonic mixers mix the associated analog signals with associated analog, harmonic signals to generate mixed, analog signals. The mixed, analog signals are combined into an output signal having an output signal bandwidth that is greater than a bandwidth of at least one of the number of DACs.Type: GrantFiled: March 20, 2014Date of Patent: July 28, 2015Assignee: TEKTRONIX, INC.Inventors: John E.

Publication number: 20120035548Abstract: Systems, kits, and methods for establishing vascular access are described. A system typically includes a radially expandable sleeve, a dilator, and a guidewire. The methods comprise positioning the guidewire through an initial tissue tract, passing the radially expandable sleeve over the guidewire through the tissue tract to a target blood vessel, and thereafter passing the dilator over the guidewire and through the radially expandable sleeve to effect radial expansion of the sleeve. Use of the sleeve reduces the risk of injuring tissue surrounding the tissue tract by lessening the axial forces imparted to the tissue. Kits comprise at least the radially expandable sleeve together with instructions for use.Type: ApplicationFiled: October 13, 2011Publication date: February 9, 2012Inventors: Andrew J. MacKenzie, John E. Carlson

Patent number: 7522661Abstract: A method of producing of a two-dimensional probability density function eye diagram and Bit Error Rate eye arrays generates a two-dimensional PDF array of a correlated waveform record of a data pattern under test which is convolved with a two-dimensional probability density function (PDF) array of the uncorrelated jitter and noise in the data pattern under test. The resulting aggregate two dimensional PDF array of the correlated waveform record pattern with uncorrelated jitter and noise is divided into unit intervals and the unit intervals are summed to generated a two-dimensional PDF eye diagram array. The two-dimensional PDF eye diagram is processed to generate a two-dimensional Bit Error Rate eye array.Type: GrantFiled: July 25, 2005Date of Patent: April 21, 2009Assignee: Tektronix, Inc.Inventors: Michael A.
