English

Subject field(s)
  • Simulation (Cybernetic Systems)
  • Machine-Tooling (Metallurgy)
  • Collaboration with WIPO
CONT

One known technique involves predicting the volume of a finished combustion chamber from a raw cylinder head casting... In this method, laser scanning is used to create a computer model of the cylinder head geometry. A computer technique called "virtual machining" is then used to emulate the real world machining process and transform the computer model of the raw casting to that of a finished combustion chamber.

OBS

virtual machining: data validated by Canadian subject-field experts from École Polytechnique de Montréal, MasterpieceVR and McGill University.

French

Domaine(s)
  • Simulation (Systèmes cybernétiques)
  • Usinage (Métallurgie)
  • Collaboration avec l'OMPI
CONT

Initialement, l'usinage virtuel sert à former les débutants pour leur permettre de comprendre sensoriellement les processus d'usinage.

  • Operación de mecanizado (Metalurgia)
  • Colaboración con la OMPI
CONT

El mecanizado virtual es una herramienta que permite la simulación de un proceso de mecanizado con la intención de optimizar los parámetros de corte (avance, profundidad de pasada y velocidad de corte) que intervienen en este sin necesidad de recurrir al método de prueba y error debido al coste y al tiempo que este conlleva [...]

English

Subject field(s)
  • Eye Surgery
DEF

A technique used to help pull the peripheral iris away from the trabecular meshwork in the angle of the eye.

CONT

Iridoplasty, also known as gonioplasty, uses low-energy laser burns to the peripheral iris in order to widen the anterior chamber angle and/or break peripheral anterior synechiae.

Record 3 2010-09-24

English

Subject field(s)
  • Lasers and Masers
DEF

A single laser system whose beam is split into twenty separate beams, each of which is amplified several hundredfold before being focused into a chamber in a spherical array of light that converges upon the tiny target.

OBS

The 20-beam laser, completed in 1977, provided more power, better control over conditions, higher temperature, and greater fuel compression than previous lasers, including delivering 10 kilojoules of energy in a billionth of a second.

OBS

It is called Shiva, after the multiarmed Hindu god of both creation and destruction.

French

Record 4 2004-12-06

English

Subject field(s)
  • Physics
  • Analytical Chemistry
CONT

Uranium laser deposited on a Si substrate and transferred in vacuo to analysis chamber for photoemission spectrometry(PES).

OBS

spectrometry : The use of spectrographic techniques for deriving the physical constants of materials.

OBS

photoemission : The ejection of electrons from a solid (or less commonly, a liquid) by incident electromagnetic radiation.

Key term(s)
  • photo-emission spectrometry, photo emission spectrometry

French

Domaine(s)
  • Physique
  • Chimie analytique
CONT

La spectrométrie de photoémission permet de caractériser la surface d'un matériau plutôt que son volume (i.e. identification des éléments, quantification, énergie de liaison) mais l'analyse dépend des éléments constitutifs et des conditions expérimentales utilisées. La variation d'énergie de liaison des photoélectrons caractéristiques des éléments présents est exploitée afin de remonter au degré d'oxydation de ces derniers.

Key term(s)
  • spectrométrie de photo-émission, spectrométrie à photo-émission
