Patent number: 10812251Abstract: A master node of a distributed acquisition system is provided. The master node includes a communication interface for interfacing between a control component and a bus and the control component. The bus is coupled to one or more slave nodes distributed in the acquisition system. The control component is configured to acquire a configuration that provides a definition for a packet interval, wherein the packet interval definition provides an adequate timing margin to ensure that communication packets transmitted by the master node and the one or more slave nodes occur only at harmonics of the packet interval definition, distribute a time reference packet of the communication packets based on the packet interval definition via the bus to all of the slave nodes of the distributed acquisition system, and schedule transmission of communication packets transmitted by the master node via the bus to the one or more selected slave nodes based on the packet interval definition.Type: GrantFiled: December 18, 2018Date of Patent: October 20, 2020Assignee: Simmonds Precision Products, Inc.Inventor: Owen Daniel Evans

Publication number: 20200192846Abstract: A slave node of one or more slave nodes and a master node of a distributed acquisition system and a method of synchronizing communication of the slave node is provided. The method includes acquiring a configuration that provides a definition for a packet interval, wherein the packet interval definition provides an adequate timing margin to ensure that communication packets transmitted by the master node and the one or more slave nodes occur only at harmonics of the packet interval definition. The method further includes receiving master communication packets from the master node via the bus, determining a start time of at least one most recent master communication packet of the master communication packets received from the master node, calculating a synchronization time based on the start time, and starting transmission of slave communication packets to the master node based on the synchronization time.Type: ApplicationFiled: December 18, 2018Publication date: June 18, 2020Applicant: Simmonds Precision Products, Inc.Inventor: Owen Daniel Evans

Patent number: 10378859Abstract: A multimode seeker includes an imager and an image processor. The imager is configured to capture image data received by the multimode seeker during a search period and a track period, wherein the search period includes a plurality of search cycles, and wherein a duration of each of the plurality of search cycles is equal to a predetermined pulse period plus a predetermined drift period. The image processor is configured to detect at least one laser candidate based upon the image data and to track the least one candidate laser during the track period.Type: GrantFiled: March 7, 2017Date of Patent: August 13, 2019Assignee: Rosemount Aerospace Inc.Inventor: Owen Daniel Evans

Patent number: 5918267Abstract: A system for detecting leaks from buried pipes which transport fluids other than water. The system includes a pipe for transporting the fluid, a fluid-wicking member which lies beneath the pipe, is wetted by the fluid when the fluid leaks from the pipe, and is permeable to water, and a fluid sensor which contacts the fluid-wicking member and is capable of detecting the fluid.Type: GrantFiled: June 4, 1997Date of Patent: June 29, 1999Assignee: Raychem CorporationInventors: Owen Daniel Evans, Patrick K.
