Abstract: Methods, systems, and apparatuses are described for wireless communication using the mmW spectrum. In particular, antenna structures may include arrays of antenna elements to deal with line-of-sight issues. Further, antenna structures may be configured to produce a beam (e.g., signal) that is relatively narrow and has a relatively high gain to deal with losses, such as mentioned above. Still further, antenna structures may be configured to provide beam steering (e.g., beamforming) capability. Such antenna structures may be designed to be relatively compact to deal with the limited real estate available on modern wireless communication devices (e.g., cellular telephones).

Abstract: A gerotor pump is provided with a pump housing defining a chamber and having an inlet and an outlet separated by a planar surface. The planar surface defines a notch connected to the outlet. An inner gear member is rotatably and eccentrically supported within an outer gear member. The inner gear member defines a series of external teeth with a first tooth defining a fluid passage therethrough and a second tooth independent of fluid passages. The fluid passage is defined by an aperture extending axially through the first tooth fluidly connected to a channel extending across the first tooth on an end face of the inner gear member. The passage and the notch cooperate to form a fluid pathway for pressure relief and reduced tonal noise in the pump by disrupting harmonics during operation.
