Patent CA-3056921-A1 (CA)
Title: Wearable display device utilizing a composite field of view
Inventor: SCHOWENGERDT BRIAN T
IPC: G02B27/00
Filed: 2018-03-22
Abstract: A wearable display device suitable for use in an augmented reality environment is disclosed. The wearable display device can include a projector configured to project light through diffractive optical elements that then distributed the light to multiple display regions. Each of the display regions can be arranged to project light out of the wearable display device towards an eye of a user. Since each of the display regions are positioned in different locations with respect to an eye of a user, the result is that each display region directs light in a different direction. In this way the apparent field of view for a user of the wearable display can be substantially increased.

IPC: G02F1/015
Filed: 2018-05-11
Abstract: The present disclosure provides a system and method for a tunable ENZ material that can vary the absorption of radiant energy. The tunable ENZ material can act as a broadband absorber advantageously using a stack of ultrathin conducting layers having an epsilon-near-zero (ENZ) regime of permittivity at different wavelengths. The conducting materials can include at least partially transparent conducting oxide or transition metal nitride layers with different electron concentrations and hence different ENZ frequencies for a broadband range of energy absorption. The layer(s) can be directly tuned to various frequencies to achieve high levels of absorption at deep subwavelength ENZ thicknesses. An applied electric bias can create electron accumulation / depletion regions in an ENZ semiconductor device and allows control of plasma frequency and hence high levels of absorption in the device. Further, for a stack of layers, the carrier concentration can be altered from layer to layer.

Abstract: Appareil pour étendre et rétracter une housse sur une plateforme d'un véhicule transportant un matériau dans celle-ci. L'appareil comprend un ensemble bras, un moteur et une bobine de bâche pour enrouler et dérouler une bâche pour découvrir et recouvrir la plateforme de véhicule. Pour améliorer la tension de bâche, des rouleaux sont prévus sur un support dans lequel est placée la bobine lorsque la bâche est déroulée. Les emplacements de frottement coulissant que l'on trouve dans des conceptions connues sont évités et remplacés par un frottement roulant. Le frottement roulant est considérablement inférieur au frottement coulissant et, par conséquent, des niveaux supérieurs de couple de sortie de moteur peuvent être incorporés lors de l'étirement plus serré de la bâche avant l'arrêt du moteur. À ce stade de l'opération de couverture, la plateforme de véhicule est recouverte et la bâche est maintenue tendue. Le support peut également être conçu pour fournir un effet de freinage à la bobine pour faciliter le maintien de la bâche en tension.
