Patent number: 11145142Abstract: A method of detecting and identifying road surface defects is provided. Motion and position information is received from a plurality of vehicles. A profile is retrieved for a particular vehicle from a database of vehicle profiles by using an identifier of the particular vehicle. One or more criteria are identified for detecting a particular type of road surface defect based on the retrieved profile of the particular vehicle. Upon determining that the received motion and position data satisfies the identified criteria, a detection of a road surface defect of the particular type and a location associated with the detected road surface defect based on the received position information is reported.Type: GrantFiled: September 6, 2016Date of Patent: October 12, 2021Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Timothy J.

Patent number: 10613279Abstract: A structure to couple light to a waveguide is described. In an example, a light source of the structure may emit light from an emission point towards a lens of the structure. The light source may be disposed at a location such that the emission point of the light source is offset from a center of the lens. The lens may be integrated in a substrate of a structure comprising the light source. The lens may refract the light emitted from the emission point at an angle. The angle may be based on the offset between the emission point and the center of the lens. The structure may couple the refracted light to a coupler of the waveguide at an incident angle.Type: GrantFiled: September 25, 2019Date of Patent: April 7, 2020Assignee: International Business Machines CorporationInventors: Russell Budd, Marc A.

Patent number: 9912413Abstract: An optical phase modulator includes an input source that is configured to receive a light source. There is an output operative to provide a phase modulated output signal based on the received light source. There is a first optical coupler configured to split the light source into a first optical path of a Mach Zehnder Interferometer (MZI) and a second optical path of the MZI. A static phase shifter is configured to provide a static phase shift to the first optical path. There is a phase modulator in the second optical path. There is a second optical coupler configured to combine the first optical path and the second optical path. The first and second optical couplers are tuned such that the phase modulated optical signal at the output provides a substantially constant amplitude that is independent of a change in loss introduced by the phase modulator.Type: GrantFiled: August 26, 2016Date of Patent: March 6, 2018Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Nicolas Dupuis, Benjamin G.

Patent number: 5974868Abstract: The present invention is a contamination measuring device and method of using the same according to a Chemical Mechanical Polishing (CMP) brush cleaner equipment/technology. A collection device is mounted in a brush cleaning device for collecting effluent which flows off of a wafer. The effluent is passed to a particle counter which measures the contamination levels of the effluent. A computer stores the data collected by the particle counter and computes the particles per liter of effluent and provides real time data. The contamination of the effluent corresponds to the contamination of the brushes in the cleaning device and therefore is means for predicting when the brushes in the cleaning device should be replaced.Type: GrantFiled: August 20, 1998Date of Patent: November 2, 1999Assignee: International Business Machines CorporationInventors: Donald M.
