  • Patent number: 12504646
    Abstract: The eyeglasses includes a glasses frame and two temples. The glasses frame has two opposite ends. Each of the two temples has a front end connected pivotally to a respective one of the two opposite ends of the glasses frame. Each of the two temples have a section that is flexible so that, by applying lateral forces to the two temples, the temples are convertible between an outwardly curved state where rear ends of the two temples are spaced apart from each other at a first distance, and an inwardly curved state where the rear ends of the two temples are spaced apart from each other at a second distance that is smaller than the first distance.

  • Patent number: 12413314
    Abstract: An optical single sideband generation system comprising a RF signal generator generates a sawtooth drive voltage with a first frequency. A laser source provides the initial optical carrier with a second frequency that is modulated by a first phase modulator. The modulation shifts the optical carrier by the amount of the first frequency, and with added phase errors due to the imperfections of the sawtooth drive. A directional coupler allows the optical carrier to be divided into the error measurement path and the error correction path. The modulated signal goes to a phase detector that measures the phase error and converts the phase error signal to a baseband electrical signal. The optical signal at the output of the second phase modulator is the desired single sideband shifted from the original carrier with the phase errors of the signal generator suppressed by the error correction feedforward path.
