    摘要: A self-calibrating powered air purifying respirator (PAPR). The PAPR comprises an electric motor mechanically coupled to a blower; an air flow sensor, and a controller coupled to the air flow sensor and to the electric motor. The controller is configured to automatically execute a one-time self-calibration by driving the electric motor to a predefined operation point, receiving an indication from the air flow sensor, determining a reference parameter based on the indication from the air flow sensor, and storing the reference parameter, wherein after completion of the one-time self-calibration the controller controls the electric motor based on the stored reference parameter.

    摘要: Embodiments relate generally to noise reduction techniques and systems for use with supplied air respirators. Typical embodiments may comprise porous elements located within a respirator system operable to alter the air flow pattern through the system and therefore reduce noise created in the system. These porous elements might be located within an inhalation valve, a breathing hose and/or a muffler block housing of a respirator system.

    摘要: An angular position sensor (100) for determining angular position includes a shaft (105) having a threaded portion (108), and a structure for engaging an external application (119). The shaft (105) includes a first permanent magnet (114). A nut (116) is threaded on the threaded portion (108). The nut (116) is formed from a first magnetic permeable material or includes a second permanent magnet (118). At least one constraint (122) is coupled to the nut (116) for preventing rotational movement of the nut (116) while allowing linear motion of the nut (116). A first magnetic sensor (120) is positioned along a length of the threaded portion (108) of the nut (116) for measuring a linear position of the nut (116). A second magnetic sensor (124) is provided for measuring an angular position of the shaft (105). Signal processing circuitry (130) is coupled to receive outputs from both the first magnetic sensor (120) and second magnetic sensor (124) for calculating a parameter relating to an angular position of the rotatable member.
