Patent number: 10948093Abstract: A check valve comprises a valve housing defining an opening and a plurality of flapper elements each having a proximal end and a distal end. The flapper elements are pivotally mounted to the valve housing at their proximal ends for pivotal movement between a closed position, in which they block the flow of fluid through the opening and an open position in which they permit the flow of fluid through the opening. Each flapper element is generally triangular or trapezoidal in shape such that the flapper elements together create a generally conical or frustoconical surface when the valve is in the closed position. A resilient band extending around a circumference of the conical or frustoconical surface defined by the plurality of flapper elements in the closed position for biasing the flapper elements towards the closed position.Type: GrantFiled: June 7, 2019Date of Patent: March 16, 2021Assignee: HAMILTON SUNSTRAND CORPORATIONInventors: Pawel Czarnecki, Lukasz Bogdanowicz

Publication number: 20200236288Abstract: A process to partition a video feed to segment live player activity includes receiving, on a first recurring basis, a transmission of a central video feed from a first camera. The central video feed is calibrated against a spatial region represented in at least two dimensions that is encompassed by the central video feed. The process includes receiving, on a second recurring basis, a respective time-stamped position information from each tracking device in a plurality of tracking devices. Each tracking device is worn by a corresponding subject on the spatial region and transmits positional information that describes a time-stamped position of the corresponding subject in the spatial region. The process uses the received information and the calibration to define a first sub-view of the central video feed associated with a first subject. The first sub-view comprises a corresponding sub-frame associated with the first subject.Type: ApplicationFiled: January 20, 2020Publication date: July 23, 2020Inventors: Erik Schwartz, Michael Naquin, Christopher Brown, Steve Xing, Pawel Czarnecki, Charles D.

Publication number: 20200234543Abstract: In an embodiment, a process to predict a probability of a future event occurring in a present competition includes receiving time-stamped position information of one or more participants in the present competition. The time-stamped position information is captured by a telemetry tracking system during the present competition. The process uses the time-stamped position information to determine a first play situation of the present competition. The process determines, based on at least the first play situation and playing data associated with at least a subset of one or both of a first set of one or more participants and a second set of one or more participants, a prediction of the probability of a first future event occurring at the present competition.Type: ApplicationFiled: January 20, 2020Publication date: July 23, 2020Inventors: Erik Schwartz, Michael Naquin, Christopher Brown, Steve Xing, Pawel Czarnecki, Charles D.

Publication number: 20200230501Abstract: In an embodiment, a process to predict an outcome of a competition includes receiving time-stamped position information of participant(s), the time-stamped position information captured by a telemetry tracking system during the competition. The process includes calculating while the competition is ongoing a covariate parameter for each of one or more participants at a point in time, where each respective covariate parameter is derived from the time-stamped position information of a corresponding participant at the point in time. The process includes predicting the outcome of the competition, as of the point in time, based at least in part on (i) a difference between a calculated competitor strength of the first competitor the second competitor based on historical data associated with the competitors, and (ii) the calculated first covariate parameter(s).Type: ApplicationFiled: January 20, 2020Publication date: July 23, 2020Inventors: Erik Schwartz, Michael Naquin, Christopher Brown, Steve Xing, Pawel Czarnecki, Charles D.

Publication number: 20200230502Abstract: A process to track and provide positional information for display on a remote device includes receiving, on a first recurring basis, time-stamped position information of participant(s) in a competition. The time-stamped position information is captured by a telemetry tracking system during the competition and describes a time-stamped position of each of one or more corresponding participants in a predetermined spatial region. The process includes communicating at least a subset of time-stamped position information to the remote device on a second recurring basis. The remote device uses the time-stamped position information to overlay a representation of one or more of said participants onto a first virtual reproduction of at least a relevant portion of the predetermined spatial region to produce and display an instance of a compiled virtual scene that shows a respective position of each of the participant(s) on the first virtual reproduction of the predetermined spatial region.Type: ApplicationFiled: January 20, 2020Publication date: July 23, 2020Inventors: Erik Schwartz, Michael Naquin, Christopher Brown, Steve Xing, Pawel Czarnecki, Charles D.

Patent number: 10578224Abstract: A valve housing for a check valve comprises a housing body for mounting a pair of flapper elements and a pair of valve openings extending through said valve body. The valve openings are separated by a web which extends from one side of the valve body to an opposed side of the valve body. The valve body and web define sealing surfaces around the valve openings on one face of the valve housing. The web comprises a slot extending into the web from a face thereof on said one face of said valve housing and extending along a length of the web.Type: GrantFiled: June 14, 2017Date of Patent: March 3, 2020Assignee: HAMILTON SUNDSTRAND CORPORATIONInventors: Modest Reszewicz, Pawel Czarnecki

Publication number: 20200056708Abstract: A valve assembly is provided, the valve assembly comprising a body that defines a fluid flow path between an inlet and an outlet with a frangible member between the inlet and the outlet across the fluid flow path so as to block fluid flow The valve assembly also includes means for rupturing the frangible member, means for biasing the rupturing means into contact with the frangible member and means for retaining the rupturing means away from the frangible member. A magnet is spaced apart from the retaining means a non-magnetic sleeve is disposed between the magnet and the retaining means. The non-magnetic sleeve block a magnetic field provided by the magnet. Also included are means for removing the non-magnetic sleeve, wherein, when the non-magnetic sleeve is removed, in use, the magnetic field attracts the retaining means to release the rupturing means to cause rupture of the frangible member.Type: ApplicationFiled: May 16, 2019Publication date: February 20, 2020Inventors: Lukasz WIKTORKO, Pawel CZARNECKI

Publication number: 20200018408Abstract: A valve assembly includes a valve housing defining a flow path to allow fluid flow between a first end configured to be connected to a fluid source and a second end and that defines a valve seat in the flow path, a valve member located in the valve seat moveable within the housing between a closed position and an open position, and biasing means within the valve housing and connected to the valve member to bias the valve member in the closed position. The valve member has formed therein across at least part of the radial dimension of the flow path, a frangible part configured to rupture if, while the valve member is in the closed position, a pressure and/or temperature acting on the frangible part exceeds a rupture threshold, thus allowing flow along the flow path.Type: ApplicationFiled: April 16, 2019Publication date: January 16, 2020Inventors: Pawel CZARNECKI, Lukasz WIKTORKO

Patent number: 10295070Abstract: The present disclosure relates to a rotary check valve, which utilizes the rotation of a rotary element to open and close the valve, rather than pivoting of hinge flappers, such as in other check valve designs. The rotary element is rotatably mounted to a valve plate which features shrouded openings that define windows. A plurality of vanes extending from the rotary element are used to close or open the windows in response to a reverse or forward fluid flow, respectively. This action opens or closes the valve. This design may reduce the force exerted on the valve components when the valve opens and closes, when compared to a pivoting hinge flapper design.Type: GrantFiled: May 9, 2017Date of Patent: May 21, 2019Assignee: HAMILTON SUNDSTRAND CORPORATIONInventors: Pawel Czarnecki, Theodoros Sergiadis
