Abstract: Apparatuses and methods for improved noise reduction and voice capture in respiratory protective devices are provided. For example, an example respiratory protective device includes at least one fan component secured to the respiratory protective device, at least one sound sensor component positioned within the respiratory protective device and generating a detected sound signal, and a controller component electronically coupled to the at least one fan component. In some examples, the controller component is configured to receive a detected fan speed signal, retrieve a corresponding noise profile data object, generate a noise-reduced sound signal, and transmit the noise-reduced sound signal to a data communication component.

Abstract: Various embodiments are directed to determining an elevator car position within an elevator shaft using footprint representations or descriptions of frequency spectrum data at reference positions along the elevator shaft. In one aspect, an example method is provided. The method includes determining reference frequency spectrum data for each of a plurality of reference positions along the elevator shaft and generating a footprint associated with each reference position based at least in part on a plurality of frequency peaks within the reference frequency spectrum data for each reference positions. The method further includes obtaining real-time frequency spectrum data associated with the elevator car within the elevator shaft and determining an estimated position of the elevator car based at least in part on comparing the real-time frequency spectrum data with a plurality of footprints associated with the plurality of reference positions.

Abstract: Various embodiments are directed to a radar reflector configured for radar-based distance measurements for determining a position of an elevator car within an elevator shaft. The radar reflector comprises three or more triangular panels defining a pyramidal frustum volume having a base plane and an upper plane that are parallel. The pyramidal frustum volume is configured to directly reflect radar signals originating from a radar transceiver back to the radar transceiver based at least in part on the triangular panels being mutually perpendicular at a projected apex above the upper plane. The reflected radar signals reflected by the radar reflector have substantially parallel trajectories with the original, pre-reflected radar signals emitted by the radar transceiver. The triangular panels of the radar reflector being mutually perpendicular advantageously maintains direct reflection of radar signals in spite of any potential horizontal tilt of the radar reflector to a certain extent.
