Patent number: 11099276Abstract: Systems and methods for identifying which of a plurality of signal types received by a global navigation satellite system (GNSS) receiver includes a spoofing signal. One method may include, for each particular signal type of the plurality of signal types, excluding the particular signal type, calculating a parameter of a GNSS receiver based on the received wireless signals having a plurality of remaining signal types, and calculating a residual score based on a variability associated with calculating the parameter, the residual score being one of a plurality of residual scores. The method may also include identifying an outlier of the plurality of residual scores and identifying which of the plurality of signal types includes a spoofing signal based on the outlier.Type: GrantFiled: June 7, 2018Date of Patent: August 24, 2021Assignee: Trimble Inc.Inventors: William Lentz, Stuart Riley

Patent number: 10705222Abstract: A GNSS receiver for generating distance estimates from multiple GNSS satellites. The GNSS receiver includes an antenna and an RF front end coupled to the antenna configured to generate a plurality of samples related to a received signal. The GNSS receiver includes a correlator coupled to the RF front end configured to perform various operations including performing three correlations on the plurality of samples with three local code to generate three correlation results, where the three local codes are shifted in time or distance with respect to each other. The GNSS receiver includes a processor for defining a first slope using the first correlation result and the second correlation result, defining a second slope using the second correlation result and the third correlation result, and defining a code discriminator as a sum of the first slope and the second slope.Type: GrantFiled: April 4, 2017Date of Patent: July 7, 2020Assignee: Trimble Inc.Inventors: William Lentz, Nicholas Talbot

Publication number: 20090293163Abstract: A new and distinct variety of Jonagold apple tree, ‘Lentz Jonagold,’ originating as a limb mutation of the Malus domestica variety of ‘Rubinstar’ (US Plant Pat. No. 7,167). This new variety is unique from its parent and other Jonagold cultivars in the early coloration of the fruit, the high percentage of coloration of the fruit and the red coloration of the leaf petiole and mid-vein.Type: ApplicationFiled: May 20, 2008Publication date: November 26, 2009Applicant: International Plant Mangement, Inc.Inventor: William Lentz

Patent number: 6990256Abstract: An optical modulator includes first and second modulator segments. The first and second modulator segments form an optical signal path for an optical signal. The optical modulator also includes an electrical signal path capable of receiving and carrying a modulation signal, which is applied to the optical signal at the first and second modulation segments to generate a modulated optical signal. An inductive element may be disposed between electrical inputs to the first and second modulator segments. The optical modulator may be an electro-absorption modulator (EAM). The inductive element may be an inductor or a transmission line segment.Type: GrantFiled: June 20, 2002Date of Patent: January 24, 2006Assignee: TriQuint Technology Holding Co.Inventors: John Michael Geary, Joseph Michael Freund, Frank Stephen Walters, Thomas Gordon Beck Mason, Charles William Lentz

Patent number: 6895134Abstract: The invention is an optoelectronic device and method of fabrication where at least two optical devices are formed on a single semiconductor substrate, with each optical device including an active region such as a multi-quantum well region. The active devices are spatially separated and optically coupled by a passive waveguide formed over the substrate which provides butt joints with the active regions. The butt joints can be optimized independently from the active regions thus improving yield.Type: GrantFiled: November 10, 2001Date of Patent: May 17, 2005Assignee: Triquint Technology Holding Co.Inventors: Kenneth Gerard Glogovsky, Charles William Lentz, Abdallah Ougazzaden, Claude Lewis Reynolds, Jr.

Patent number: 6556605Abstract: A mesa stripe buried heterostructure semiconductor laser with no intediffusion of atoms between doped regions and a method of its formation are disclosed. A double dielectric mask is used to form the mesa stripe. The first mask is then partially etched and a Si-doped InP layer is selectively grown. The first and second mask are subsequently etched away and an InP(Zn) clad layer, along with a Zn-doped InGaAs contact layer, are formed. This way, the resulting structure has no contact between the InP(Zn) clad layer and the InP(Fe) layer, and the dopant atoms interdiffusion is suppressed.Type: GrantFiled: February 29, 2000Date of Patent: April 29, 2003Assignee: Triquent Technology Holding, Co.Inventors: Gleb E.

Patent number: 6437868Abstract: A system for measuring the thickness of a wafer while it is being thinned this disclosed. The system and method provide integrating an optical reflectometer into a common wafer thinning apparatus. Using reflected optical signals from the top and bottom of the wafer, the thickness of the wafer is determined with time based calculations in real-time while thinning is occurring. Once the desired thickness has been reached, the thinning operation is halted. By performing the measurement in-situ, this system and a method prevent scrapping of wafers which are overthinned and the reloading of wafers which are too thick. Since an optical reflectometer is used, the measurement is contactless, and thus prevents possible damage to wafers during measurement.Type: GrantFiled: October 28, 1999Date of Patent: August 20, 2002Assignee: Agere Systems Guardian Corp.Inventors: David Gerald Coult, Duane Donald Wendling, Charles William Lentz, Bryan Phillip Segner, Gustav Edward Derkits, Wan-ning Wu, Franklin Roy Dietz
