Abstract: An apparatus can include a display, a facial interface, and a connection between the display and facial interface. The display can at least translate or rotate relative to the facial interface via the connection.

Abstract: A shoe journal bearing having a series of shoes with a leading edge distribution groove, and bleed grooves so as to prevent oil starvation of any area of the shoe, and an oil feed tube connected between the outer end of the oil distribution groove and an oil supply hole in a shoe retaining ring. The oil feed tube is provided with O-ring seals to seal the oil supply system against leakage and directs the oil against the working faces of the shoes where it is needed and prevents the oil from leaking into areas where it is not needed or useful.

Abstract: A thrust bearing for use with a shaft having a collar mounted thereon, comprising a base ring, a thrust bearing shoe having a leading edge connected to a trailing edge by an inner diameter edge and an outer diameter edge and having a working face with a bearing liner on its surface, a series of shoes positioned on the base ring, a shoe pivot on each shoe allowing the shoe to pivot in any direction, an oil distribution groove formed in the working face near the leading edge of the shoe and extending radially for substantially the entire distance between the inner and outer diameter edges of the shoe, said oil distribution groove having an inner end and an outer end connected by a leading edge and a trailing edge, and a bleed groove extending radially from the inner end of the oil distribution groove to the inner diameter edge of the shoe for supplying oil to the inner diameter area of the shoe downstream of the bleed groove which downstream inner diameter area would otherwise be starved by oil by the centrifug
