Abstract: A camera includes a housing that defines a camera housing cavity and a lens assembly partially disposed in the camera housing cavity. The lens assembly comprises a lens, a lens cover, and a lens cavity that is defined between the lens and the lens cover. The camera includes a fluid path that extends from the lens cavity, through the camera housing cavity, and to an external environment. The camera includes a seal that partially obstructs the fluid path and is configured to equalize a humidity in the lens cavity with a humidity in the external environment.

Abstract: An image capture device includes a housing and a lens cavity comprising an external lens that separates the lens cavity from an exterior environment. The lens cavity is connected with an inside of the housing. The image capture device includes a door positioned on the housing that opens the inside of the housing to the exterior environment. The image capture device includes a vent positioned on housing so that moisture can be vented from housing and the lens cavity to the exterior environment.

Abstract: An image capture device includes a housing; a lens cover disposed on the housing; a lens disposed within the housing beneath the lens cover; a lens cavity defined between the lens and the lens cover; a battery cavity defined within the housing; a lens vent fluidly coupling the lens cavity and the battery cavity; a battery disposed within the battery cavity; and a desiccant patch coupled to a side of the battery. Moisture introduced into the battery cavity by the battery, the lens cavity, or the lens vent is absorbed by the desiccant patch.

Abstract: Breathable membranes for lens assemblies are described. For example, a system may include a lens barrel having an inner channel extending from a first end of the lens barrel to a second end of the lens barrel. The lens barrel can include one or more inner lenses positioned within the inner channel. The lens barrel has a vent hole in a side of the lens barrel that extends from the inner channel to an exterior surface of the lens barrel. The system includes a membrane attached to the lens barrel and positioned to cover the vent hole. The membrane has pores large enough to permit nitrogen gas to flow through the membrane and the vent hole.

Abstract: Briefly, example methods, apparatuses, and/or articles of manufacture are disclosed that may be implemented, in whole or in part, to facilitate and/or support one or more operations and/or techniques for a system controller for a series hybrid powertrain, such as employed for propulsion of a hybrid electric aircraft, for example.

Abstract: Disclosed is a rotor for an electrical machine includes a rotor hub comprising a multifaceted surface extending along a perimeter of the rotor hub. Each facet of the multi-faceted surface may have a substantially planar surface. A plurality of permanent magnet assemblies is disposed circumferentially around the multifaceted surface. Each individual permanent magnet assembly of the plurality of permanent magnet assemblies is coupled to the substantially planar surface of a corresponding facet.
