  • Safety device
    Patent number: 7429929
    Abstract: A safety device includes a safety module (11), a data bus (12) and one or several transmitters (15, 16, 17, 18, 19, 20). The safety module transmits a pulse train (one dynamic signal) over the bus (12) constituting a loop, whereby the pulse train is connected to each of the transmitters, wherein the pulse is phase inverted.

  • Proximity switch, a target, a system of such proximity switches and targets, and a method of determining the presence of a target by a proximity switch
    Patent number: 6603306
    Abstract: A proximity switch for detecting a target in proximity with the proximity switch as a wireless transmitter for transmitting a first pulsed signal having a first carrier frequency to the target. The proximity switch also includes a wireless receiver for receiving a second pulsed signal having a second carrier frequency different from the first carrier frequency from the target. The proximity switch has a controller for providing an output indicative of whether a predetermined correspondence is satisfied between the first and second pulsed signals.

  • Two hand control of working apparatuses
    Patent number: 6392169
    Abstract: A safety device for control of working apparatuses, e.g. presses, for which start and operation modes depend on essentially simultaneous activation of two separate operating devices, which are each controlled by the respective hands of the operator. Each operating device consists of two separate push buttons. The push buttons are arranged in a housing at a mutual distance from each other, which requires a two-hand operation, e.g. with at least two fingers. The push buttons are situated at a distance from each other.
