A fire suppressant storage device () comprises: a tank () having a first port (), a second port (), and an interior () for storing fire suppressant. A discharge assembly () is mounted to the first port and comprises: a discharge valve (); and a discharge conduit (). The discharge conduit is at least partially within the interior and has an interior and an exterior. A liquid level measurement assembly is mounted to the second port and comprises: a tube () at least partially within the interior and having: an exterior and an interior sealed relative to the surrounding tank interior. A float () surrounds the tube and has one or more magnets () and having a range of motion. A plurality of magnetic field sensors () are along a carrier () within the tube interior. The carrier extends from a proximal end to a distal end. The plurality of magnetic field sensors () comprise: a first plurality of one-dimensional sensors (); and at least two three-dimensional sensors () distally of the first plurality.

Adaptable suppression tank level sensor

A method of monitoring a conveyance apparatus within a conveyance system is provided. The method including: obtaining a starting location position probability distribution of the conveyance apparatus within the conveyance system; detecting motion of the conveyance apparatus away from the probable starting location for a period of time; determining a distance traveled by the conveyance apparatus during the period of time; determining a direction of motion of the conveyance apparatus during the period of time; and determining a probability of the conveyance apparatus being at each of a plurality of possible destination locations at a conclusion of the period of time in response to the starting location position probability distribution and at least one of the distance traveled, the direction of motion, and the period of time.

Conveyance apparatus location determination using probability

A communications system includes a root node; a plurality of nodes in communication with the root node, the plurality of nodes defining a mesh network; the root node configured to: determine a time delay to each node of the plurality of nodes; transmit audio data to the plurality of nodes, the plurality of nodes configured to produce audio corresponding to the audio data; transmit a delay code to the plurality of nodes, each of the plurality of nodes producing the audio corresponding to the audio data at a time corresponding to the delay code.
