VIEWING HEAD [3 fiches]

Fiche 1 2025-03-27

Anglais

Subject field(s)
  • Simulation (Cybernetic Systems)
  • Collaboration with WIPO
CONT

Smart eyewear is defined as eyewear incorporating a near-to-eye display. As used herein, near-to-eye display means a display, device, or system, such as a retinal projector, virtual retinal display, visualization element, head-mounted display, heads-up display, or other near-to-eye system, typically worn on the head of a user that generates an image near the eye. In a smart eyewear configuration, a display device is often mounted adjacent to an edge of each of the wearer's eyes and an image is typically displayed in the center of each lens. The location of the displayed image, therefore, forces the wearer to gaze in a direction to view the image generated by the display. Typically positioned near the user's eye, the display is aligned to the central region of the user's field of view to allow review of the displayed information with little or no head movement. This enables the user to view the display while also viewing the area outside the central region and interacting with the surrounding environment. In another embodiment, the displayed image is aligned to a region other than the central region of the user's field of view.

CONT

Near-eye display devices are configured to present images to a user via a display that is positioned close to the user’s eyes. For example, a head-mounted augmented reality display device may be worn on a user’s head to position a near-eye display directly in front of a user’s eyes. A near-eye display may be at least partially see-through to allow a user to view a real-world background in combination with displayed virtual objects. This may allow virtual objects to be displayed such that the virtual objects appear to exist within the real-world environment.

CONT

The technology provides one or more embodiments of a near-eye display (NED) device system. An embodiment of a NED device system comprises a near-eye display device including a near-eye support structure and a near-eye display (NED) supported by the near-eye support structure and having a display field of view. The NED system further comprises an image generation unit supported by the near-eye support structure which outputs image data which is optically coupled to the near-eye display (NED).

OBS

near-to-eye display; near-eye display: data validated by Canadian subject-field experts from École Polytechnique de Montréal, MasterpieceVR and McGill University.

[…] se contempla que al menos una pantalla […] comprendida en el dispositivo […] no permita ver al usuario a través de ella (es decir, que no sea transparente), siendo preferentemente de tipo NED (siglas en inglés de la expresión "near-eye display" o pantalla cercana al ojo) […]

Fiche 2 2000-04-28

Anglais

Subject field(s)
  • Burners and Steamfitting
  • Ovens, Furnaces and Boilers (Heating)
DEF

A pipe, mounted to the front plate of a combustion chamber, through which an optical flame detector sights the burner flame.

CONT

The Forney Dual Fuel Horn Igniter assembly consists of a mounting plate, combination oil and gas gun, High Energy Spark Igniter (HESI), 6" combustion air tube, flame detector and horn. The mounting plate retains the oil/gas gun, HESI and flame detector guide pipe. The flame detector head is mounted on a 1" sight pipe which provides an unobstructed view of the flame inside the horn.

CONT

This fibre optic viewing head extension is particularly useful for solving the sighting problems associated with tilting or movable burners. The flame envelope from this type of burner can be tilted from a horizontal position up or down as much as 30 degrees. It would be impossible to follow this flame pattern with a fixed sighting through the wind-box. Welding the tip guide(lens end) of this viewing head extension to the movable air compartment nozzle solves this problem. This viewing head extension can also be used for those applications where it is impossible to find a clear unobstructed view of the flame using a standard sight pipe. Here again the viewing head extension is mounted inside the furnace for a clear unobstructed view of the flame.

Fiche 3 1998-04-03

Anglais

Subject field(s)
  • Video Technology
  • Audiovisual Techniques and Equipment
  • Amplifiers (Electronics)
DEF

An amplifier capable of passing the wide range of frequencies necessary for television picture information.

CONT

Amplifiers are often called by the kind of signals they amplify, such as audio amplifiers, video amplifiers, R.F. (radio frequency) amplifiers.

CONT

A video amplifier is one that takes the small electrical signal from the output of a television camera or video tape recorder video head and amplifies it for viewing on a video monitor.

Français

Domaine(s)
  • Vidéotechnique
  • Audiovisuel (techniques et équipement)
  • Amplificateurs (Électronique)
DEF

Montage destiné à amplifier les signaux électriques vidéo, c'est-à-dire sur une bande de fréquences très large pouvant s'étendre de 50 Hz à 6 MHz.

CONT

Si l'on désire brancher plus de 10 moniteurs ou une plus grande longueur de câble, il faut intercaler dans l'installation un amplificateur vidéo.
