Publication number: 20220290723Abstract: A torque-transfer component has splines configured for engaging a corresponding feature of another component, at least a portion of each spline being hardened before a friction-reducing surface coating is applied to the splines. The splines are preferably hardened by nitriding, carburizing, induction hardening, or laser hardening, and the friction-reducing coating preferably comprises diamond-like carbon or tungsten carbide. The coating can be applied using, for example, physical vapor deposition, chemical vapor deposition, chemically assisted physical vapor deposition, autocatalytic electroless deposition, electroplating, or an oxygen fuel gun.Type: ApplicationFiled: March 14, 2022Publication date: September 15, 2022Applicant: Textron Innovations Inc.Inventors: Ron Woods, Gary Dale Hall, Scott David Poster, Lance William Weihmuller, Charles Hubert Speller

Patent number: 9747691Abstract: The technology disclosed relates to tracking movement of a real world object in three-dimensional (3D) space. In particular, it relates to mapping, to image planes of a camera, projections of observation points on a curved volumetric model of the real world object. The projections are used to calculate a retraction of the observation points at different times during which the real world object has moved. The retraction is then used to determine translational and rotational movement of the real world object between the different times.Type: GrantFiled: July 2, 2015Date of Patent: August 29, 2017Assignee: LEAP MOTION, INC.Inventors: David S. Holz, W. Dale Hall

Patent number: 8620397Abstract: A method and apparatus are described that permit an analyte concentration to be estimated from a measurement in the presence of compounds that interfere with the measurement. The method reduces the error in the analyte concentration in the presence of interferents.

The method reduces the error in the analyte concentration in the presence of interferents. The method includes the use of a set of measurements obtained for a large population having a range of known analyte and interfering compound concentrations. From a sample measurement, which may or may not be one of the population, interferents likely to be present are identified, and a calibration coefficient is calculated.

Patent number: 6825044Abstract: A device and method for determining analyte concentrations within a material sample are provided. A modulating temperature gradient is induced in the sample and resultant, emitted infrared radiation is measured at selected analyte absorbance peaks and reference wavelengths. The modulating temperature gradient is controlled by a surface temperature modulation. A transfer function relating the surface temperature modulation to a modulation of the measured infrared radiation is provided. Phase and magnitude differences in the transfer function are detected. These phase and magnitude differences, having a relationship to analyte concentration, are measured, correlated and processed to determine analyte concentration in the material sample. A method for adjusting an analyte measurement is provided. The method provides a hydration correction process for calibration and correction whereby analyte concentrations within the material sample may be determined.Type: GrantFiled: November 21, 2002Date of Patent: November 30, 2004Assignee: Optiscan Biomedical CorporationInventors: Peng Zheng, Jennifer H.
