Abstract: The technology relates to a heat sealing system (400). For instance, the heat sealing system may include a sealer assembly (800) including a pair of heat sealing bars (830, 840) configured to generate heat seals. The heat sealing system may also include a positioning (900) assembly including a platform (910) and a motor (952). The sealer assembly may be mounted to the positioning assembly, and the motor may be configured to move the sealer assembly towards and away from an edge of a table (1600).

Abstract: Aspects of the technology relate to propulsion systems for high altitude, long duration balloons, such as balloons that operate in the stratosphere for weeks, months or longer. A propeller assembly is used to provide lateral directional adjustments, which allows the balloon to spend more time over a desired region, reduce the return time to the desired region, reduce fleet overprovisioning, and increases the safety case by additional controls and avoidance abilities. A control assembly manages operation of the propeller assembly, including setting the pointing direction, speed of rotation and determining when to turn on the propeller and for how long. The propulsion system including the control and propeller assemblies is rotatable around a connection member of the balloon. Such rotation is independently adjustable from any rotation of the balloon's payload. The propeller blades may be made of plastic, which reduces weight and cost while providing sufficient speed at stratospheric altitudes.

Abstract: Systems and devices are disclosed herein that provide or relate to modular accessory devices for a wearable device, such as a glasses-style head-mountable device (HMD). Illustrative systems may include a first frame component having an accessory slot accessible via an entry point on a transverse surface of the first frame component, a second frame component movably coupled to the first frame component, and one or more accessory devices that each have a slot-mating feature shaped for insertion into and removal from the accessory slot via the entry point. The second frame component may be movable between a first position in which the second frame component blocks access to the entry point, and a second position in which the second frame component allows access to the entry point.

Abstract: Systems and methods for mounting a motor to a receiving device of a UAS are disclosed herein. The motor may include a number of protruding elements, each protruding element including a shank segment having a first diameter and a head segment having a second diameter that is larger than the first diameter. The receiving device may include a base configured to couple the receiving device to the UAS, a first sidewall extending upwardly from a first side of the base, and a second sidewall extending upwardly from a second side of the base. Both the first and second sidewalls may include at least one receptacle. The head segment of each protruding element may be configured to interlock with one or more of the receptacles of the first sidewall or the second sidewall when the protruding elements are inserted between the first sidewall and the second sidewall of the receiving device.

Abstract: An electronic device enclosure with sliding and pivoting doors. An opening of the electronic device enclosure provides access to electronic componentry. A first door and a second door are for covering the opening, the first door movably coupled and opposably slidable to the second door such that a single action to open the first door is operable to open the second door by sliding the second door in a substantially opposite direction.

Abstract: An expansion module latch mechanism including an expansion module and a latch release is described. The expansion module has a recess for receiving a retaining latch external to the expansion module for retaining the expansion module positioned with respect to an expansion module sleeve. The latch release is attached to the expansion module for expelling a retained latch from the recess. An expansion module bay latch mechanism for retaining an expansion module positioned with respect to a module sleeve is described. The expansion module bay latch mechanism has a module sleeve having a latch clip positioned on a side wall of the module sleeve. The latch clip includes a latch adapted to interfit with a recess in an expansion module and a paddle connected to the latch which, in response to contact with the expansion module, urges the latch into the recess.

Abstract: A data storage cartridge includes a first housing and a second housing forming an inner chamber with an open front end and an open rear end. An information storage device is positioned within the chamber. A pair of intermediate strips are positioned lengthwise between the first housing and the second housing which hold together the first and second housing. A front end cap is positioned in the open front end to close the chamber. A rear end cap is positioned in the open rear end to close the chamber.
