Abstract: A loudspeaker includes a housing that has a plurality of walls, which together define an acoustic cavity. An electro-acoustic transducer is mounted to a front wall of the housing, and a motion axis of the electro-acoustic transducer is offset from a centroid of the front wall. The loudspeaker is configured to be stacked with an other loudspeaker of identical construction in a fist configuration such that the stacked loudspeakers radiate acoustic energy to produce an omnidirectional radiation pattern; and in a second configuration such that the stacked loudspeakers radiate acoustic energy to produce a cardioid radiation pattern. The loudspeaker includes keyed features which do not interlock and thereby inhibit stacking when the loudspeaker is in a first orientation relative to the other loudspeaker, and which interlock to allow stacking when the loudspeaker is in a second orientation relative to the other loudspeaker.

Title: Load-securement process and device
Inventor: MARSHALL DWIGHT L
IPC: B65D90/00
Filed: 2021-03-11
Abstract: Various embodiments of the present disclosure provide load-securement devices and processes for securing loads in a shipping container. Generally, each load-securement device includes a base and two wings each having a corner-engaging end. The wings are attached to the base and are movable relative to one another and to the base from a compact configuration in which a first distance separates the corner-engaging ends to a securement configuration in which a second greater distance separates the corner-engaging ends. Since the load-securement device is more compact when the wings are in the compact configuration (as compared to the securement configuration), it is easier to attach to a shipping container—and particularly to a front corner post of the shipping container—as compared to a similar load-securement device that has immovable wings fixed in the securement configuration.
