Wakeboats, wakeboat displays, and systems and methods of measuring and indicating wakeboat potential
Patent number: 11753116Abstract: A wakeboat creates a wake, the performance level of the wake varying depending upon the mass of the wakeboat, the wakeboat including a hull; an engine supported by the hull; a controller supported by the hull; a processor coupled to the controller; a memory coupled to the processor; a sensor configured to measure at least one parameter of the wakeboat, the controller being coupled to the sensor and being configured to receive data from the sensor, the controller being configured to derive the present mass of the wakeboat from said sensor data, the controller being configured to determine the present wake performance level of the wakeboat based on the present mass of the wakeboat; and a tablet computer coupled to the controller, the controller being configured to use the tablet computer to indicate the present wake performance level of the wakeboat.Type: GrantFiled: January 23, 2020Date of Patent: September 12, 2023Assignee: Skier's Choice, Inc.Inventors: Richard Lawrence Hartman, Brian Anthony Ewasko, Matthew Douglas Brown, Jeffrey David Harrison, Zachary Thomas Davis -
Publication number: 20230084963Abstract: A method, device, and system for detecting a current leak in a traction power rail. Magnetic or electrical properties of the rail are measured. The measurements are performed using a rail instrument that senses the properties around the rail at various times while the instrument is being moved down the rail, such as using a cart or train. The rail instrument may be a flux concentrator or open Rogowski coil. The locations of the rail, about which the readings are taken by the rail instrument, may be determined and correlated with the measurements themselves. The method may comprise measuring the magnetic field of the rail along a length of the rail, and identifying a leak based on differences between the magnetic field measurements. The system may comprise a cart comprising the rail instrument and a location instrument.Type: ApplicationFiled: April 9, 2021Publication date: March 16, 2023Inventors: Matthew Gorczyca, Mark James Mitchell, Patrick Henry McGinn, Michael Morgan Campbell, Matthew Douglas Brown

Patent number: 11525338Abstract: A system for tethering a subsea blowout preventer (BOP) or well head is disclosed. In at least one embodiment, the system comprises an interface associable with the BOP, and more than one anchors disposed about the BOP. Each anchor is configured to carry or support a tensioning system arranged in operable association with a respective tether. Each tether is arranged so as to link a respective anchor with a respective operable means associated with the BOP. Furthermore, each of the respective operable means are configured in operable association with the interface such that tension in the tethers can be adjustable either individually or together as a group of two or more tethers, by way of the interface.Type: GrantFiled: March 12, 2018Date of Patent: December 13, 2022Inventors: Daniel Forster, David Archibald Cree, Timothy Reginal Marshall, Alex Paul Taylor, Matthew Douglas Brown

Patent number: 11438751Abstract: A wakeboat has a hull, the hull forming a wake when moving forward in the water, with a left quiet region and a right quiet region in the wake. The hull may exhibit rotation around one or more of its roll, pitch, and yaw axes which affects the quiet regions in the wake. A gyroscope supported in the hull may be used to rotate the hull around one or more axes. Such rotation may be used to create a surf left and/or surf right configuration, and measured via one or more sensors. Other systems and methods are also provided.Type: GrantFiled: November 2, 2020Date of Patent: September 6, 2022Assignee: Skier's Choice, Inc.Inventors: Richard Lawrence Hartman, Matthew Douglas Brown, Travis Lane Turley

Patent number: 10479461Abstract: A wakeboat has a hull, the hull forming a wake when moving forward in the water, with a left quiet region and a right quiet region in the wake. The hull may exhibit rotation around its yaw axis which affects the quiet regions in the wake. Yaw rotation may be measured via one or more sensors. Yaw measurement may be used to control the hull and quiet regions. A trim tab is supported by the hull at the stern of the hull. The trim tab comprises a primary subtab and a secondary subtab. One or more actuators may be optionally included to reposition the trim tab more into, or more out of, the water to create a surf left and/or surf right configuration. Other systems and methods are also provided.Type: GrantFiled: June 24, 2019Date of Patent: November 19, 2019Assignee: Skier's Choice, Inc.Inventors: Richard Lawrence Hartman, Matthew Douglas Brown, Travis Lane Turley

Patent number: 10040522Abstract: A wakeboat has a hull, the hull forming a wake when moving forward in the water, with a port disturbance and a starboard disturbance in the wake. Left (port) and right (starboard) trim tabs are installed at the stern of the hull. Each trim tab comprises a primary subtab and a secondary subtab. Actuators may be optionally included to reposition the trim tabs more into, or more out of, the water. Such repositioning causes the disturbance on one side of the wake to be selectively repositioned to the other side of the wake, enlarging a quiet region on the side of the wake on which the repositioned disturbance was originally positioned. Other systems and methods are also provided.Type: GrantFiled: April 4, 2018Date of Patent: August 7, 2018Assignee: Skier's Choice, Inc.Inventors: Richard Lawrence Hartman, Matthew Douglas Brown, Travis Lane Turley

Patent number: 8126663Abstract: An electronic signal level detection system and method are provided. The method receives an analog input signal having a variable voltage and compares the input signal voltage to a threshold. A detection signal is generated for input signal voltages exceeding the threshold in a periodic first time frame. In a second periodic time frame (following the first time frame), a count is updated in response to the generated detection signals. The count is used to create a metric representative of the difference between the input signal voltage and the threshold. The count is incremented in response to the generating a detection signal (“1”) in the first time frame, and decremented in response to not generating a detection signal (“0”) in the first time frame.Type: GrantFiled: February 27, 2010Date of Patent: February 28, 2012Assignee: Applied Micro Circuits CorporationInventors: Matthew Douglas Brown, Sheldon James Hood, Guy Jacque Fortier, Stan Harry Blakey
