  • Patent number: 12119621
    Abstract: A magnetic induction device is provided for triggering an electric spark discharge in response to a variable voltage. The device includes an inductor; a resistor series having first and second resistors; and a discharge device. These are arranged in a receiver circuit in which the inductor, the resistor series and the spark gap are disposed in parallel. The inductor connects between the first and second resistors to a gate electrode of the discharge device. Magnetic flux induces a current into the electrode responsive to the receiver circuit temporarily overlapping the inductor, thereby inducing the spark.

  • Patent number: 12116094
    Abstract: An exemplary inventive molding device includes two mold components characterized by matching rounded-star shapes. Each mold component includes eight congruent rounded-tip projections and eight congruent apertured sections separated from each other by the projections and describing a ring shape. The projections correspond to the equiangular points of a star. Each section has a medial hole and is interposed between and connects two projections. The mold components are joined so that their respective projections and holes are even with each other and fasteners are installed through the holes. Appropriate introduction and curing of a castable material inside the joined mold components produces a flexible device suitable for use as part of a biomimicking soft robot.

  • Publication number: 20240340082
    Abstract: A communication method including emitting laser pulses as a signal using one or more transmitters at an atmospheric point. Plasma is generated at the atmospheric point to radiate omnidirectional light. The plasma from the atmospheric point is detected using one or more receivers. The one or more receivers have a direct line-of-sight to the atmospheric point to receive the signal from the one or more transmitters via the omnidirectional light generated by the plasma. The signal is demodulated from the transmitted plasma at each receiver, thereby transmitting information encoded on the signal.

  • Patent number: 12104972
    Abstract: Multiplexed fiber optic sensors are able to monitor a multitude of sensor positions along an optical fiber from a single interrogation point. A long-standing goal is to increase the length of fiber and the number of multiplexed sensors without significantly compromising performance or increasing the size, weight, power and cost of the fiber and interrogation system. A technique is provided for performing extremely long-range, multiplexed fiber optic strain sensing in an efficient manner. This technique utilizes a serial optical frequency comb based interrogation system to probe an array of sensors placed along a single optical fiber.
