Abstract: Methods, apparatus, and articles of manufacture to minimize command dynamics of a satellite are disclosed. An example apparatus includes a steering law module to calculate a first set of vectors to maneuver a space vehicle, and calculate a second set of vectors based on projecting the first set of vectors onto a fixed plane. The apparatus further includes an attitude controller to generate an attitude command based on the first and the second sets of vectors to prevent an unplanned rotation by the space vehicle.

Abstract: An electronic device having several modifications designed to prevent liquid ingress into an opening (or openings) of the electronic device is disclosed. For example, the electronic device includes a SIM tray having a sealing element designed to provide a seal at an opening that receives the SIM tray. The sealing element may include a first section and a second section extending from the first section, with the first section designed to bend with respect to (and in some cases collapse onto) the second section. The electronic device may further include an audio module fitted with a sealing element. The sealing element may include extensions extending away from a main body of the sealing element, with some extension designed to engage the audio module, and other extensions designed to engage an audio module interface. The sealing element provides a seal against liquid ingress into the audio module.

Abstract: Energy efficient satellite maneuvering is described herein. One disclosed example method includes maneuvering a satellite that is in an orbit around a space body so that a principle sensitive axis of the satellite is oriented to an orbit frame plane to reduce gravity gradient torques acting upon the satellite. The orbit frame plane is based on an orbit frame vector.

Abstract: An electronic device having liquid-resistant modifications that prevent liquid ingress into an opening (or openings) in an enclosure of the electronic device is disclosed. For example, the electronic device may include a coating formed from a liquid-resistant material that is applied internally to the enclosure. The electronic device may further include a frame that carries a protective transparent layer designed to cover a display assembly. In order to secure the frame with the enclosure, the electronic device may include an adhesive assembly disposed over an outer perimeter of the coating. The adhesive assembly may include several adhesive parts initially separate from one another. However, with the adhesive parts between the frame and the enclosure, the adhesive parts can be compressed by the frame and the enclosure, causing the adhesive parts to expand and engage each other. As a result, the coating and the adhesive parts provide a seal against liquid.

Abstract: An electronic device may be provided with a housing in which electrical components are mounted. The housing may include a metal portion that serves as ground. An antenna for the electronic device may be formed from metal traces on an antenna support such as a flexible printed circuit. The flexible printed circuit may be mounted to a speaker box. The speaker box may have one or more walls formed from metal plates. A metal plate in a speaker box may be coupled to a metal clip. The metal clip may be shorted to a metal stiffener that overlaps a tail portion of the flexible printed circuit. The metal stiffener may have an opening that is aligned with an opening in the metal clip. A metal fastener such as a screw may pass through the openings to short the metal clip, stiffener, and metal plate to ground.

Abstract: This application relates to a portable electronic device includes at least a device housing having walls that define a cavity, the walls having edges that define an opening that leads into the cavity. Component assembly features used to secure components received through the opening to each other and/or to the walls during an assembly operation, and a protective cover formed of transparent material and disposed within the opening and secured to the housing.
