One embodiment is directed to a user display device comprising a housing frame mountable on the head of the user, a lens mountable on the housing frame and a projection sub system coupled to the housing frame to determine a location of appearance of a display object in a field of view of the user based at least in part on at least one of a detection of a head movement of the user and a prediction of a head movement of the user, and to project the display object to the user based on the determined location of appearance of the display object.

Display system and method

An interactive head-mounted eyepiece with an integrated processor for handling content for display and an integrated image source for introducing the content to an optical assembly through which the user views a surrounding environment and the displayed content, wherein the height of the image source is at least 80% of a display active area width of the optical assembly.

A transmitting unit (1) has a transmitter for transmitting signals of coded information about a position (12) close to the unit in a space substantially unreachable by a satellite-based navigating system so as to provide a receiver (22) arranged on a moving object (21) present in said space with this position information for determining the position of this object The transmitter is adapted to normally be in an inactive non-transmitting state, and the unit further comprises means adapted to detect movement of a said object within said space and activate the transmitter to transmit said si gnals only when a movement of a said object in said space is detected

A transmitting unit

The present disclosure relates devices and a method for monitoring a display image (2) in a transparent optical projection display. They disclose a display image monitor (1) comprising a fiber optic face plate (4) and an image sensor (5). The fiber optic face plate (4) comprises a first surface (4a) with optic fiber ends and a second surface (4b) with corresponding optic fiber ends and transfers light from the first surface (4a) to the second surface (4b) through the optic fibers, wherein the first surface abuts against a part (2a) of the display image (2) at a focused image plane (2b) and thus the light of the part of the display image enters the optic fiber ends and wherein the second surface is arranged to direct the part of the display image to the image sensor, thereby transferring the part of the display image to the image sensor.

Face plate in transparent optical projection displays

The present disclosure relates to a head up or head mounted display arrangement and a method for presenting at least one image via at least one surface element of a head up or head mounted display arrangement The arrangement comprises at least one image generating element (301, 302) arranged to generate an image in a first image plane (346', 346"), at least one surface element, and a fibre optic face plate (340)The face plate is arranged in relation to the at least one image generating element such that the first surface lies at a first image plane A second image plane lies at the second surface and the at least one surface element is arranged in the beam path from the second surface The first image plane comprises a plurality of first part image planes each associated with an individual first part surface of the fibre optic face plate and/or the second image plane comprises a plurality of second part image planes each associated with an individual second part surface of the fibre optic face plate

A head-up or head-mounted display arrangement and a method for presenting at least one image via at least one surface element of a head-up or head-mounted display arrangement

The present disclosure relates to a head up or head mounted display arrangement and a method for presenting at least one image via at least one surface element of a head up or head mounted display arrangement. The arrangement comprises at least one image generating element (301, 302) arranged to generate an image in a first image plane (346´, 346''),at least one surface element,and a fibre optic face plate (340).The face plate is arranged in relation to the at least one image generating element such that the first surface lies at a first image plane. A second image plane lies at the second surface and the at least one surface element is arranged in the beam path from the second surface. The first image plane comprises a plurality of first part image planes each associated with an individual first part surface of the fibre optic face plate and/or the second image plane comprises a plurality of second part image planes each associated with an individual second part surface of the fibre optic face plate.
