  • Publication number: 20180368722
    Abstract: An electrooculography (EOG) signal capture system comprises a) a sensor array adapted for being located at one of a left or right ears of a user and/or for fully or partially being implanted in the head at left or right ears of a user, the sensor array comprising a number Ns of electric potential sensors, respectively, for sensing respective electric potentials from the user's head, where Ns is larger than or equal to two, b) electronic circuitry coupled to the sensor array and configured to provide at least two different beamformed signals (SBF1, SBF2), each being representative of a weighted combination of said electric potentials, or of signals derived therefrom, and wherein a difference between said at least two different beamformed signals (?PBF=SBF1?SBF2)—at least in a specific electrooculography mode of operation—represents an electrooculography signal (?PEOG) from one or both eyes of said user. A single-sensor EOG-system is further proposed. The invention may e.g.

  • Patent number: 10126514
    Abstract: Fiber optic equipment that supports independently translatable fiber optic modules and/or fiber optic equipment trays containing one or more fiber optic modules is disclosed. In some embodiments, one or more fiber optic modules are disposed in a plurality of independently translatable fiber optic equipment trays which are received in a tray guide system. In this manner, each fiber optic equipment tray is independently translatable within the guide system. One or more fiber optic modules may also be disposed in one or more module guides disposed in the fiber optic equipment trays to allow each fiber optic module to translate independently of other fiber optic modules in the same fiber optic equipment tray. In other embodiments, a plurality of fiber optic modules are disposed in a module guide system disposed in the fiber optic equipment that translate independently of other fiber optic modules disposed within the module guide system.

  • Patent number: 10114048
    Abstract: Example implementations relate to circuits. For example, an implementation includes a detection circuit including a comparator circuit. The comparator circuit includes a first input terminal, a second input terminal, and an output terminal. The detection circuit also includes a reference voltage circuit to provide a set point voltage to the comparator circuit via the first input terminal. The detection circuit further includes a diode to reduce the set point voltage from a first magnitude to a second magnitude when the first magnitude is equal to or lower than a magnitude of the load voltage.

  • Publication number: 20180302971
    Abstract: A lighting driver (500) includes a controller (560) which controls the lighting driver to selectively operate in one of two different states, including a first state (850) wherein the output current is substantially constant regardless of the RMS value of an AC Mains in put voltage (15) applied across AC Mains connection terminals (502), and a second state (860) wherein the slope of the input impedance across the AC Mains connection terminals is maintained to be positive regardless of the AC Mains input voltage. The controller is configured to latch the lighting driver into the second state whenever the RMS value of the AC Mains voltage is less than a minimum RMS threshold voltage for a time period greater than a first threshold time period (TTHRESHOLD_1), or greater than a maximum RMS threshold voltage for a time period greater than a second threshold time period (TTHRESHOLD_2).

  • Publication number: 20180267295
    Abstract: A fiber scanning system can have optimized performance by substantially matching the natural frequencies of the fiber scanning system's actuator and fiber optic scanning element. By matching the natural frequencies, the fiber scanning system can increase the maximum distance that the tip of the fiber optic scanning element may be driven relative to a resting position. Such an effect may be produced because matching the natural frequencies of the fiber scanner allows for larger amplitudes to be achieved. It should be noted that the natural frequency of the scanning system can be selected to avoid excitation frequencies that could destabilize the system. In this way, the system as a whole may act as a tuned mass damper or a tuned resonance structure, thereby improving scan performance while maintaining a stable scanning system.

  • Publication number: 20180179106
    Abstract: A method of fabricating a variable diameter fiber includes providing a fiber optic cable, focusing a laser beam at a predetermined location inside the fiber optic cable, and creating a damage site at the predetermined location. The method also includes focusing the laser beam at a series of additional predetermined locations inside the fiber optic cable and creating a plurality of additional damage sites at the additional predetermined locations. The damage site and the additional damage sites define a variable diameter profile. The method further includes exposing the fiber optic cable to an etchant solution, preferentially etching the damage site and the plurality of additional damage sites, and separating a portion of the fiber optic cable to release the variable diameter fiber.

  • Patent number: 9844114
    Abstract: Techniques are described to allow a low-cost light fixture to produce light with a relatively high color rendering index (CRI) across a range of color temperatures. A rectified AC voltage may be provided to multiple groups of light-emitting diodes (LEDs) having characteristics related to a range of color temperatures and a target CRI level. The multiple groups of LEDs may be controlled based on a received control signal, such that the combined groups of LEDs produce combined light having a produced color temperature within the range of color temperatures, and having a produced CRI level that is approximately the target CRI level. In some implementations, the received control signal is modified by a modification circuit, and the multiple groups of LEDs may be controlled based on the modified control signal.
