Publication number: 20240077007Abstract: The present disclosure relates to a detection system for detecting a failure in a fluid path of a fluid system, the detection system including: at least one pipe comprising a pipe wall which defines a fluid path for the transfer of fluid and at least one electrically conductive element extending along the at least one pipe and which forms an electrical signal path for a first electrical signal which indicates a state of the at least one pipe; and, an electrical terminal electrically connected to the at least one electrically conductive element so that the first electrical signal is transmitted to the electrical terminal via the electrical signal path.Type: ApplicationFiled: January 7, 2022Publication date: March 7, 2024Inventors: Nicolas NIVARD, Scott SCHWARTZ, Chris CORBETT, Philip HARPER, Samuel HILL, Nicholas WALLIS, Stephen SWAIN

Patent number: 11572069Abstract: The present disclosure relates to a method of controlling gear selection in a transmission of a vehicle in response to a directional shift requested by an operator and to a control system for controlling gear selection to manage directional shifts in vehicles, from a first direct to a second direction (e.g. forward to reverse). The method compares the current transmission output speed with a predetermined direction shift threshold transmission output speed. If the current transmission output speed is less than or equal to the predetermined direction shift threshold transmission output speed, the transmission is caused to execute a direction shift from the initial first direction gear to the same second direction gear, or a next highest second direction gear if there is no second direction gear which corresponds to the initial first direction gear.Type: GrantFiled: August 15, 2019Date of Patent: February 7, 2023Assignee: Caterpillar Inc.Inventors: Robert Nicholas Harper, Abhishek Awana, Christopher L. Wynkoop, Mariappan Paramasivan

Patent number: 11566703Abstract: A method of controlling gear selection in a vehicle transmission comprises detecting a change in a direction control signal (DCS) from a neutral signal state. If the current TOS is less than or equal to a predetermined neutral shift threshold TOS, the transmission selects one of a plurality of first direction gears if the DCS was changed to a first direction signal state or one of a plurality of second direction gears if the DCS was changed to a second direction signal state. If the current TOS is greater than the predetermined neutral shift threshold TOS, the transmission selects one of the plurality of first direction gears if a machine motion direction parameter indicates that the vehicle is moving in the first direction or one of the plurality of second direction gears if the machine motion direction parameter indicates that the vehicle is moving in the second direction.Type: GrantFiled: February 22, 2021Date of Patent: January 31, 2023Assignee: Caterpillar Inc.Inventors: Robert Nicholas Harper, Christopher L.

Publication number: 20210025136Abstract: A method of reducing fuel consumption in a machine with an internal combustion engine. The machine has a hybrid mode in which the engine is used for simultaneous ground propulsion via a torque convertor and hydraulic implement propulsion via a hydraulic pump. The engine controller uses a first engine map that defines primary operating constraints. The method comprises: obtaining an initial torque limit from a torque limit profile providing operating constraints that fall within the primary operating constraints. The method further comprises: implementing a torque limit that corresponds to the initial torque limit value such that in an event that a torque demand exceeds the torque limit then the engine speed will drop below the desired engine speed. The method further comprises, in an event that torque converter speed ratio between engine and ground propulsion drops below a speed ratio threshold, removing the torque limit profile and reverting to primary operating constraints.Type: ApplicationFiled: July 8, 2020Publication date: January 28, 2021Applicant: Caterpillar Inc.Inventor: Robert Nicholas HARPER

Publication number: 20190012661Abstract: Systems and related methods facilitating secure payments are discussed herein. Some embodiments may provide for a system including a payment gateway server, a tokenizer server and a detokenizer server. The payment gateway server may receive payment card data from a merchant device and provide the payment data the tokenizer server. The tokenizer server may be configured to generate one or more tokens based on the payment data and provide the one or more tokens to the payment gateway server. During payment processing, the payment gateway server may be configured to provide the one or more tokens to the detokenizer server configured to determine the payment data based on the one or more tokens to facilitate completion of a financial transaction. In some embodiments, the one or more tokens may be stored for subsequent payments. Furthermore, some embodiments may provide for secure promotion redemptions in addition or alternative to payments.Type: ApplicationFiled: January 26, 2018Publication date: January 10, 2019Inventors: Christopher Dwyer Watson, Benjamin Pierce McKean, Sean Nicholas Harper, Josh Krall, Qi Li

Patent number: 9096998Abstract: A ceiling system in one embodiment includes a longitudinally-extending support member mountable from a ceiling and a clamping bracket attachable to the support member for supporting a ceiling element. The clamping bracket includes a cavity that receives the support member at least partially therein. A resiliently deformable elastic member has a movable bearing surface positioned in the cavity of the clamping bracket. The elastic member is movable from an undeflected inactive position to a deflected active position in response to inserting the support member into the cavity of the clamping bracket. The elastic member applies a force on the support member to help retain the clamping bracket on the support member.Type: GrantFiled: June 23, 2014Date of Patent: August 4, 2015Assignee: AWI Licensing CompanyInventors: Nicholas Harper, Torquil Goodwin, Matthew Woollam
