Patent number: 11624720Abstract: Disclosed is a salinity detection device. The salinity detection device has a collection plate, a mounting frame, and a sensor portion including a predominantly non-metallic sensor. The device may be mounted in a wheel well of a vehicle via the mounting frame and the collection plate may be attached to the mounting frame and positioned behind a wheel such that water on a road surface may be splashed thereon. The collection plate is fluidically connected to the sensor portion so that water may flow through the sensor portion proximate the sensor to measure a current flowing through the water and determine a salinity thereof.Type: GrantFiled: December 13, 2019Date of Patent: April 11, 2023Assignee: Pillar Inc.Inventors: Mark Boenke, Robert Davignon, Zhan Chen, Brian Dougherty, Charles E.

Publication number: 20210381694Abstract: Hot surface igniter assemblies used in cooktops are shown and described. The hot surface igniters include a silicon nitride ceramic body with an embedded, resistive, heat-generating circuit. When energized, the circuit generates temperatures in excess of 2000° F. in under 4 seconds to ignite cooking gas such as natural gas. To prevent damage to the igniter during use or cleaning, an insulator assembly is provided which protects the distal end of the igniter ceramic body from damage while still exposing it to the cooking gas flow from the burner. In addition, a number of different terminal connection schemes for connecting the igniters to a power source are shown and described.Type: ApplicationFiled: August 23, 2021Publication date: December 9, 2021Inventors: Bruce C.

Publication number: 20150119987Abstract: An implant, and a method of designing the implant, takes into account heterogeneous bone properties. The method may be directed to designing a fixation feature of the implant using a virtual bone model. Bone property information derived from image data may be mapped to the virtual bone. A virtual model of the implant may be created, including a virtual fixation feature characterized by an input parameter. One or more simulations may be performed, the simulations being of an implantation of the virtual implant on the virtual bone. Values for at least one input parameter may be used for each simulation, each simulation resulting in a value for an output parameter. The input and output values may be analyzed to derive a relationship between the values, the relationship being used to design the fixation feature of the implant.Type: ApplicationFiled: October 28, 2014Publication date: April 30, 2015Inventors: Robert Davignon, Michael C.

Publication number: 20060217220Abstract: An instructional baseball used for the art of teaching the proper techniques of throwing a curveball is shown having a spherical body with an integrally formed fin extending from the body in a figure-8 path which extends around the outer surface of the body in a figure-8 path similar to the stitching of a conventional baseball. In other preferred embodiments an elongated V-shaped groove is formed in the outer surface of the body with a fin disposed within the groove also following the same figure-8 path as the V-groove. The fin acts as an air shield creating greater drag forces on the baseball as it is thrown through the air with a spinning motion. The greater drag forces increase the Magnus force on the ball, allowing it to curve move dramatically then that of a conventional baseball. Increasing the curve rate of the baseball will serve to help pitchers more easily see the results of their throwing techniques and ultimately improve their curveball throwing skills.Type: ApplicationFiled: June 6, 2006Publication date: September 28, 2006Inventor: Robert Davignon
