Patent number: 11968811Abstract: An industrial automation controller includes a housing with a forced convection chamber. First and second fans are releasably connected to the housing and are adapted to induce airflow through the forced convection chamber. The first and second fans are each connected to the housing by respective first and second latch systems that each include a primary latch and a secondary latch. The secondary latch imposes a time delay during removal and replacement of a fan to facilitate hot swapping of the fan with a replacement fan. A make-last/break-first contact system is provided for each fan such that the fan is shutdown in a controlled manner prior to removal of the fan from the housing. The controller monitors internal temperature and fan speed. The controller initiates, logs, and reports fault conditions based upon the monitored temperature and/or fan speed. The controller is shut down if the monitored temperature exceeds a select temperature level.Type: GrantFiled: February 1, 2021Date of Patent: April 23, 2024Assignee: Rockwell Automation Technologies, Inc.Inventors: Michael S. Baran, Jason N. Shaw, Gary D. Dotson, Bruce J. Moore, Milan Svoboda, Pavel Jicha, John C. Laur, Keith O. Satula

Patent number: 11774940Abstract: A human machine interface for an industrial automation control system includes at least one touchless input device that is adapted to be in a first state in which said human machine interface provides a first input to said industrial automation control system or a second state in which said human machine interface provides a second input to said industrial automation control system. The at least one touchless input device includes first and second touchless input sensors each configured to detect hand gestures of an operator's hand to provide input to said human machine interface based upon said gestures. The first and second touchless input sensors can be identical with respect to each other or different. In one example, one or both of the sensors are both time-of-flight sensors and one of the sensors can be an electric field proximity sensor. A method of providing a human machine interface with at least one touchless input device is provided.Type: GrantFiled: March 29, 2021Date of Patent: October 3, 2023Assignee: Rockwell Automation Technologies, Inc.Inventors: Yanbin Zhang, Xiaobo Peng, Gary D.

Publication number: 20220375293Abstract: An electronic safety function lock-unlock system includes a human-machine interface (HMI) device. The HMI device includes a touchscreen display for touch input and one or more cameras for capturing gesture input data and operator facial image data. The HMI device is operatively connected to a power switch unit or similar device for selectively interrupting conduction of electrical power to industrial equipment for safety. An operator initiates a lock operation with respect to the equipment using first touchscreen or first gesture input to perform a lock operation to disconnect the industrial equipment from electrical power. An operator initiates an unlock operation or condition (to remove a lock condition) with respect to the equipment using second touchscreen input or second gesture input. The HMI optionally require vocal confirmation from an operator of a requested lock or unlock operation.Type: ApplicationFiled: May 20, 2021Publication date: November 24, 2022Applicant: Rockwell Automation Technologies, Inc.Inventors: Yanbin Zhang, Xiaobo Peng, Gary D.

Patent number: 10873264Abstract: There is provided a powered device configured to switch between a power over Ethernet (PoE) source and an auxiliary power source without restarting the device. A PoE circuit within the device includes a minimum load circuit which enables detection of the device by PoE power sourcing equipment (PSE) even when the device is powered by the auxiliary power source. The minimum load circuit may maintain a load of around 10 mA to simulate powered components, thereby enabling the PSE to reinitiate PoE even though the powered components of the device are at that time powered by the auxiliary power source. When the power supplied to the powered components by the PSE overcomes that of the auxiliary power source, the power scheme may automatically revert to PoE.Type: GrantFiled: June 15, 2017Date of Patent: December 22, 2020Assignee: Rockwell Automation Technologies, Inc.Inventor: Gary D.
