Patent number: 11962651Abstract: In an embodiment, a method for commissioning a sensor via a communication unit includes scanning, by the communication unit, a sensor-identifying feature of the sensor to provide sensor-identifying data and sending, by the communication unit to a system controller, the sensor-identifying data. The method further includes receiving, by the communication unit from the system controller, one or more contextual prompts regarding a sensed object to which the sensor is operatively connected and, in response to the contextual prompts, sending, by the communication unit to the system controller, sensed object context information. Thereafter, the method further comprises receiving, by the communication unit from the system controller, confirmation of commissioning of the sensor. A corresponding method in the system controller, as well as corresponding apparatus, are also described.Type: GrantFiled: January 4, 2023Date of Patent: April 16, 2024Assignee: DYNAPAR CORPORATIONInventor: Robert Cachro

Patent number: 11353343Abstract: Detection of mechanical coupling slippage in rotary encoder systems is provided where position data samples are obtained from a rotary encoder coupled to rotating element and angular acceleration data is determined based on the position data samples. At least two acceleration peaks are detected in the angular acceleration data, including at least one negative acceleration peak and at least one positive acceleration peak. Slippage occurrence of the mechanical coupling are detected when an interval between a negative acceleration peak and a positive acceleration peak of the at least two acceleration peaks is less than a first time period. If at least a threshold number of slippage occurrences are detected within a second time period, a mechanical coupling error signal is generated.Type: GrantFiled: November 9, 2021Date of Patent: June 7, 2022Assignees: DYNAPAR CORPORATION, HENGSTLER GMBHInventors: Robert Cachro, Mi{hacek over (s)}él Batmend, John Reading, Ryan Kirkendall, Michael Parks, Sarah Lauterbach, Eduard Ribar

Patent number: 10077810Abstract: A sensor hub for use in machine condition monitoring comprising a rotation sensor and a wireless communication module each operatively connected to a processing device. The rotation sensor and processing device are configured to receive power from a controller of the monitored machine. One or more additional sensors, which may be associated with the monitored machine or another machine, may also be operatively connected to the processing device. In an embodiment, the additional sensors may comprise any one or more of, or any combination of, an accelerometer, a temperature sensor, an acoustic sensor, an high frequency sensor, an humidity sensor, a barometric pressure sensor, a current sensor or a proximity sensor. The wireless communication module may support an ad hoc wireless communication protocol. Further, the wireless communication module may receive additional sensor data from one or more wireless sensor nodes associated with the monitored machine or another machine.Type: GrantFiled: April 14, 2015Date of Patent: September 18, 2018Assignee: Dynapar CorporationInventors: Mark Edward Langille, Kirk Alan Mitchell, Erik John Brewster, Abhishek Sumeet Jadhav, Ferran Alberto Ayala, Scott Thomas Benigni

Patent number: 10048104Abstract: Sensor and/or power-harvesting apparatus are provided for sensing and/or harvesting energy across a relatively wide dynamic range of a driving rotational input. The apparatus may include a rotor magnet (10, 62) responsive to a driving rotational input (14, 64). Utilization of a togging effect or a magnetic spring effect results in certain rapid-rotation events where the rotor magnet can rapidly rotate regardless of a low rate of rotation of the driving rotational input. A coil assembly (28, 75) is magnetically coupled to the rotor magnet to generate a signal in response to rotation of the rotor magnet during the rapid-rotation events. This signal may be used to harvest electrical energy and/or may be processed to determine characteristics of the driving rotational input.Type: GrantFiled: November 21, 2013Date of Patent: August 14, 2018Assignee: Dynapar CorporationInventors: Edward G. Colby, Andrew N. Dames, Edward J. Taylor, Cathleen M. Clausen

Patent number: 9312086Abstract: A proximity switch (20, 20A) that snaps quickly and locks between first and second positions of movable electrical contacts (32). A magnet (42) moves a first shaft (26) toward a magnetic target (62) when the target is proximate a sensor end (43) of the switch housing (22). A spring (44) urges the first shaft (26) away from the sensor end. Movement of the first shaft causes a second spring (64) to urge a second shaft (28) in the direction of the first shaft. Next the second shaft is released (52) to move in the direction urged by the second spring. The switch may be adapted to a client cable pin configuration via an adapter plug (80) in the housing with a flexible interconnection circuit (82) folded in a chamber between the adapter plug and leads from fixed electrical contacts (38) of the switch.Type: GrantFiled: October 21, 2011Date of Patent: April 12, 2016Assignee: Dynapar CorporationInventors: Troy A.

Publication number: 20150253154Abstract: In an embodiment of a rotational sensor, a multi-pole magnet assembly comprises multiple magnets configured to rotate about a rotational axis of the rotational sensor, where the multi-pole magnet assembly is in a first plane perpendicular to the rotational axis. The magnetic sensor is arranged in a second plane also perpendicular to the rotational axis and in proximity to the multi-pole magnet assembly. Each magnet of the multiple magnets has poles aligned parallel to the rotational axis and perpendicular to the first plane of the magnetic sensor. In another embodiment, the magnetic sensor is arranged at a first radius away from the rotational axis, whereas the multiple magnets of the magnet assembly are arranged at a second radius, not equal to the first radius, away from the rotational axis. In yet another embodiment, a rotational sensor comprises a housing and rotatable shaft upon which the magnet assembly is mounted.Type: ApplicationFiled: January 21, 2015Publication date: September 10, 2015Applicant: DYNAPAR CORPORATIONInventors: Kenneth Lee Dickinson, James Arthur Fuhrman, August Allen Chasey, Mark Edward Langille, Dale Wayne Taylor
