Abstract: Apparatuses, systems, and methods comprising acoustically absorptive air ducts comprising an internally positioned structure component as an endoskeleton and an air impervious inner layer, and an acoustically absorptive foam outer layer, environmental control systems comprising such air ducts, and vehicles incorporating such environmental control systems are disclosed with methods for manufacture and installations are disclosed.

Abstract: This document discusses, among other things, an apparatus comprising a pump configured to deliver a fluid, a wireless communication port, a controller, and a housing to enclose the apparatus. The controller is configured to communicate with a second device via the communication port using an open standard wireless communication protocol. The housing includes a mechanical coupling to slidably engage the second device which includes a second wireless communication port. Slidably engaging the second device positions the first and second communication ports opposite each other to allow communication via the first and second communication ports when slidably engaged.

Abstract: One variation of a serving unit includes: a base; a wall extending from the base, including a frustoconical section, and defining a central axis; a rim extending from an upper edge of the wall; a seal extending across the rim and transiently enclosing a cavity defined by the wall and the base; a beater arranged within the cavity, configured to rotate about the central axis, including blades configured to extend along the base and up a portion of the wall, and including a drive coupling coaxial with the central axis; and a dry powdered food product arranged within the cavity and including a first quantity of flavoring, a second quantity of sweetener, and a third quantity of thickener.

Abstract: One variation of a method for preparing a frozen food product includes: following insertion of a vessel into a receiver: activating a cooling element thermally coupled to the receiver; transitioning a rotary motor from rest to a first target angular speed; and setting a first timer of a first duration; in response to expiration of the first timer and detection of contents of the vessel approximating a first target viscosity: reducing an angular speed of the rotary motor; and setting a second timer of a second duration; in response to expiration of the second timer and detection of the contents of the vessel approximating a second target viscosity: reducing the angular speed of the rotary motor; and setting a third timer of a third duration; in response to expiration of the third timer: reducing the angular speed of the rotary motor; and indicating completion of a frozen food product.

Abstract: A device for trapping and collecting snails in an aquatic environment. The device includes a basin with a lid having a top opening through which snails may enter, a floating screen to keep snails retained, and a standpipe to anchor the device to the bottom of a water body and to serve as a location for the deposit of snail eggs.
