The invention relates to an infra-red reflecting layered structure comprising a transparent substrate layer; a first metal oxide layer; a first silver containing layer, a second metal oxide layer; a second silver containing layer and a third metal oxide layer. The first, second and third metal oxide layer have a refractive index of at least 2.40 at a wavelength of 500 nm. The layered structure according to the present invention laminated on glass has a visual light transmittance (VLT) higher than 70% and a solar heat gain coefficient (SHGC) lower than 0.44. The invention further relates to the use of a layered structure as a transparent heat-mirror.

Examples of an imaging system for use with a head mounted display (HMD) are disclosed. The imaging system can include a forward-facing imaging camera and a surface of a display of the HMD can include an off-axis diffractive optical element (DOE) or hot mirror configured to reflect light to the imaging camera. The DOE or hot mirror can be segmented. The imaging system can be used for eye tracking, biometric identification, multiscopic reconstruction of the three-dimensional shape of the eye, etc.

An automated luminaire which allows for the selection of a diffuser or a hot mirror which is mounted to engage the light beam at an angle non perpendicular to the central axis of the light beam and nonparallel or not in the same plane as the diffuser. The selector is articulated in a manner to automatically engage a selector based on what other light modulators are selected to engage the light beam and to automatically oscillate or scan when there is a likelihood of damage to the hot mirror or diffuser based on how long it is engaged and / or light intensity and / or other modulators selected and or temperature sensor data in the luminaire.

This invention relates to a solar photon filter, hereafter known as the SPF, which is a combination band-pass filtering system consisting of a multiple set of cold or hot mirrors and infra-red absorbers set in a 360-degree or linear arrangement. The system removes almost all of the photons carried by waves having lengths longer than 1000 nm (nanometers)+ / −100 nm, while passing almost all of the incoming photons carried by waves having lengths shorter than 1000 nm+ / −100 nm and / or variations thereof. This is accomplished by positioning a set of cold or hot mirrors in constant optical track with the sun. Such an assembly of cold or hot mirrors allows solar photons carried by light to be split into two distinct bands of frequencies for use requiring such filtering separation.

An eyeball tracking structure comprises a heat mirror, an infrared light source and a camera. The heat mirror is arranged between a displayer in a head-mounted display device and a human eye; the camera is arranged on one side of the displayer in the head-mounted display device, connected with a control circuit and used for capturing an image of an infrared pattern reflected by the heat mirror, capturing an eye image of the human eye and transmitting an obtained composite image to the control circuit, so that the control circuit conducts compensation calculation through a sight image function,the position of a sight point on the displayer is calculated, and then the displayer is controlled to feed back and display information corresponding to the position. Therefore, speckles of infraredbeams are projected onto the heat mirror instead of being directly projected into the eyeball, and the situation that the infrared rays are directly projected onto the eyeball and cause harm can be avoided.

An instrument measuring optical properties of an eye in an entire field of vision, including refraction and aberrations, including: a frame mounted on an ophthalmologic table that can be oriented in three perpendicular directions X, Y, Z; a support surface for a head of the subject; a hot mirror; a long mirror; an illumination sub-assembly including a fiber optic head; a lens; a diaphragm; a beam splitter; and a measurement sub-assembly with two lens and two mirrors; a camera including a matrix of micro-lenses on the inlet of camera, the camera being placed on the focal plane of the micro-lenses; the frame including a motor, a shaft of which rotates in the Y direction, to which an arm is attached that can rotate on the shaft; components of the illumination sub-assembly, components of a measurement sub-assembly, and the camera with the matrix of micro-lenses being mounted on the arm.

The invention relates to a container performance acceleration method based on a nonvolatile memory. The container performance acceleration method comprises the following steps: dividing each mirror image layer in a mirror image into one of an upper boundary mirror image layer and a lower boundary mirror image layer in a container deployment process; storing the on-boundary mirror image layers intoa nonvolatile memory and selectively storing each under-boundary mirror image layer into one of the nonvolatile memory and the hard disk; obtaining a thermal image file required by the container in the container starting and / or running process, and storing the thermal image file required by the container into a nonvolatile memory; and performing access heat sorting on each mirror image at least according to the access frequency of the hot mirror image file so as to release the nonvolatile memory occupied by the mirror image with the lowest access heat when the storage space of the nonvolatilememory is insufficient. According to the method, the container deployment speed is greatly increased by optimizing the container deployment mechanism and combining with the nonvolatile memory; by optimizing the mirror image storage mechanism, the hot mirror image file is stored in the nonvolatile memory, and the container starting speed is greatly increased.
