Abstract:
An infrared bolometer (124). A waveguide (110) configured to transmit infrared radiation is arranged to be adjacent a graphene sheet (120) and configured so that evanescent waves from the waveguide overlap the graphene sheet. The graphene sheet has two contacts (330) connected to an amplifier, and a power detector connected to the amplifier. Infrared electromagnetic power in the evanescent waves is absorbed in the graphene sheet, heating the graphene sheet. The power of Johnson noise generated at the contacts is proportional to the temperature of the graphene sheet. The Johnson noise is amplified and the power in the Johnson noise is used as a measure of the temperature of the graphene sheet, and of the amount of infrared power propagating in the waveguide.
Abstract:
Techniques are disclosed for using an infrared (IR) sensor to sense flame and/or activity within an environment of a building, such as a home or office. One example embodiment provides a multi-condition sensing device that includes an IR sensor for sensing both human occupancy and fire within a given environment. Another example embodiment provides a multi-condition sensing device that includes a plurality of sensors. A first of the sensors includes an IR sensor that is adapted to sense IR radiation within a given environment. A second of the sensors is adapted to sense a second environmental condition (different than IR radiation) within the given environment. Another example embodiment provides a standalone modular sensor block with a standard communication interface to a building management system. The sensor block may act as a combo-sensor as well as an active fire detector and alarm.

Abstract Abstract Abstract The invention is a device for up-conversion of Short Wavelength Infra-Red (SWIR) images into visible images. The device comprises a sub micrometer thickness structure that is composed of several sub-layers, each having a typical thickness of tens to hundreds of nanometers. The device is composed of two main sections one on top of the other: (a) a highly efficient SWIR absorption thin layer and (b) a highly efficient organic light emitted diode (OLED). The generated visible image is emitted from the OLED through a top transparent cathode, which is deposited on the OLED.
