  • Patent number: 10912234
    Abstract: 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.

  • Patent number: 10873264
    Abstract: 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.

  • Patent number: 10338557
    Abstract: A system includes a safety controller that, in operation, interrupts power to industrial automation devices or puts the system into a safe state upon command of a human operator. The system also includes an emergency stop switch circuit actuatable by a human operator and a human machine interface in data communication with the safety controller and the emergency stop switch circuit. The human machine interface includes integrated safety circuitry that, in operation, detects a change of state of the emergency stop switch circuit and provides a signal to the safety controller to interrupt power to the industrial automation devices or put the system into a safe state.

  • Patent number: 8760878
    Abstract: Systems and methods are provided that facilitate accurate alignment of internal and external electronic components during assembly of an electronic device such that proper engagement of mating electrical connectors on the respective components is assured. To this end, a floating circuit board carrier mounts to an adaptor plate comprising a surface of the device housing and positions a circuit board such that it “floats” within the device housing. A modular component having posts molded or attached thereto is mounted to the adaptor plate such that the posts pass through clearance holes in the adaptor plate as well as through notches in the circuit board, thereby effecting proper relative alignment of the circuit board and the modular component as electrical connectors on the respective components are engaged.

  • Patent number: 5040307
    Abstract: Inaccuracies in measurement of the separation of a pitched horseshoe from a target stake are substantially reduced by a measuring device that is configured to engage the target stake such that surface anomalies in the stake do not influence the accuracy of the measurement. The measuring device is comprised of a generally elongated solid body having a generally circular aperture adjacent one end of the body, the diameter of the aperture exceeding the width of the target stake, so that the device may be placed over the stake and a far edge portion of the aperture, that is adjacent to the one end of the body, may abut against that portion of the stake which faces away from the pitching direction. A sequence of gradation markings are formed on a second portion of the flat body, which is spaced apart from the one end of the body. In accordance with a further aspect of the present invention there is provided a scoring device for providing an indication of the score of the game during the progress of the game.
