Abstract: A temperature sensor including a sapphire optical fiber and a nanoporous cladding layer covering at least a portion of the sapphire optical fiber.

Abstract: The freshness of one or more terms in a documentation, indicative of a currency of the one or more terms is computed. Each term includes one or more constituent words, and the terms are visually marked as current or out-of-date based on the computed freshness. Upon marking a term as out-of-date, a latest term for the out-of-date term is retrieved or a most possible latest term for the out-of-date term is predicted.

Abstract: An electronic device and a method for dynamically adjusting an exposure parameter of a spectral sensor. The method includes: The electronic device determines whether a Clear value is less than or equal to a first threshold; and if the Clear value is less than or equal to the first threshold, the electronic device determines whether an analog gain of the spectral sensor reaches a second threshold; and if the analog gain of the spectral sensor reaches the second threshold, the electronic device extends an exposure time of the spectral sensor; or if the analog gain of the spectral sensor does not reach the second threshold, the electronic device increases the analog gain of the spectral sensor.

Abstract: A hair cutter includes a stationary blade and a movable blade. The stationary blade includes a recess near a free end and a cutting edge on an upper side of the recess. The recess is adapted for receiving at least one string of hair. The movable blade includes a cutting edge at a free end. The cutting edge of the movable blade is movable past the cutting edge of the stationary blade to shear the string of hair.

Abstract: The present invention provides a method and a device for backing up an unread short message, both of which can store a new short message received by a mobile communication terminal in a terminal storage and back up the new short message to a subscriber identity card, and delete, when a user reads or deletes an unread short message stored in the terminal storage, a backup unread short message, which stored in the subscriber identity card, corresponding to the new short message. The method and the device of the present invention can synchronize the unread short message in the terminal storage and the subscriber identity card, so that the user will not lose the unread short message even when changing the mobile communication terminal.
