Abstract: A personal protection equipment (PPE) system with a remote user interface comprises an article of PPE including an active wireless communication device for transmitting a signal and a controller for managing settings on the article of PPE; and a communication hub including a user interface, an electronic connection to a PPE management software, and a wireless communication device. When the wireless communication device of the communication hub detects that the article of PPE is in proximity to the communication hub, the hub displays information on the user interface. The user interface displays settings for the article of PPE, and the settings can be adjusted by a user through interaction with the user interface. The wireless communication device of the communication hub transmits information related to the adjusted settings to the wireless communication device of the article of PPE; and the controller adjusts the settings on the article of PPE.

Abstract: Sensored mixer, comprising a mixing device for mixing two or more components to produce a mixed liquid at a mixer output, and a property sensor for determining a property of a liquid, the property sensor comprising a) a channel comprising a sensing zone through which the liquid flows; b) two electrodes for generating an electric field of one or more sensing frequencies in the sensing zone; c) a data storage device comprising a pre-stored set of calibration data representing calibration impedance responses measured previously at the one or more sensing frequencies and at different property values of the property of an identical liquid; and d) a device to repeatedly i) generate between the electrodes an electric field of in the sensing zone; ii) sense between the electrodes, a response impedance; iii) derive from the response impedance a property value of the property of the liquid, using the pre-stored set of calibration data representing calibration impedance responses, wherein the property sensor is in fluid communication with the mixer output such that the mixed liquid can flow from the mixer output through the sensing zone. A method for sensing a property of the liquid and a data set of calibration data representing calibration impedance responses usable with the sensor and the method are also disclosed.
