  • Patent number: 9484915
    Abstract: A non-contact proximity switch having a first part and a second part which do not need to be in physical contact to detect proximity of the first and second parts. The first part is arranged to be connected to a reset circuit including an indicator light and a reset switch having a reset button. The first part includes a reset mechanism for machine safety, and the reset mechanism includes a signal generator and a signal detector. The reset mechanism is arranged to, upon indication that a reset is required, generate a signal so as to switch-on said indicator light, and the reset mechanism is further arranged to detect when the state of a connected reset switch corresponds to a state where the reset button is being pressed.

  • Patent number: 9053253
    Abstract: A monitoring system including a first and a second portion. The first portion includes a controller for receiving a code sequence. The first portion is configured to connect the system to a common data bus. The first portion is configured to provide a synchronization signal to the second portion when the two portions are in a predetermined position. The second portion includes a controller for providing the code sequence to the first portion and the first portion being further configured to output the code sequence for verification by a verification entity.

  • Patent number: 8899633
    Abstract: The present disclosure relates to a lock device, such as for safety functions, which includes a displaceable lock bolt, which can cooperate with a receiver in order to provide a locked position and unlocked position. The lock bolt includes a guide portion in a second lock bolt portion which, in response to a guiding device applying a force to the lock bolt, guides the lock bolt from the unlocked position to the locked position. The guiding device, in the locked position, is prevented from displacing the lock bolt to the unlocked position. The lock bolt is arranged to be displaced from the locked position to the unlocked position through influence of an external force applied to a first lock bolt portion.
