  • Patent number: 10312429
    Abstract: A composite material fabricated using a novel process and materials. The piezoelectric and magnetostrictive layers of the composite material are coated, layered, and bonded using a process known as LTTLP bonding. The resulting magnetoelectric composite fibers are bonded to a polyimide film based copper flexible circuit using a room temperature curing epoxy. The sensor that results is an MEMFC that outperforms conventionally fabricated MEMFCs.

  • Patent number: 10293376
    Abstract: A bender bar acoustic transducer capable of exciting at least three resonance modes is provided. The provided bender bar acoustic transducer may be capable of exciting a second resonance mode by configuring a first portion of a piezoelectric element to contract while a second portion of the piezoelectric element expands when voltage is applied to electrodes coupled to the piezoelectric element. The bender bar acoustic transducer may be further configured such that the first portion and the second portion of the piezoelectric element both contract and/or expand to excite a first resonance mode. The bender bar acoustic transducer may be used in downhole and well logging applications.

  • Patent number: 10184493
    Abstract: A flapping fan for cooling electronic devices includes an elongated piezo actuator, two supporting members, two connecting members, and a thin blade. The supporting members are attached to the piezo actuator at its two ends, while the blade is connected to the piezo actuator through the connecting members. When activated by an AC signal, the piezo actuator oscillates around its neutral position, which causes the blade to oscillate. The blade rotates around its leading edge when its direction of motion changes, keeping its angle of incidence lower than ninety degrees. This helps the flapping fan to generate a significant air flow.

  • Patent number: 10147255
    Abstract: A smart lock system and method having a smart lock element, a data entry interface element; a mechanically operated power generator such as a dynamo as the sole power source; and an electronic control element. A separate controller is in communication with the smart lock element, only when the dynamo provides power to the smart lock. The controller element constantly receives and store updated key code information from a remote location source. With the providing of the operating energy to the smart lock the electronic control element receives and stores updated key code information from the controller, if any, prior to any unlocking activation of the locking mechanism. The electronic control element compares stored key code information with entered key codes and the locking mechanism is unlocked thereafter with entry of a valid key code corresponding to a key code stored in the electronic control element.

  • Patent number: 10126817
    Abstract: In an embodiment for use with a portable device, a haptic feedback system creates a haptic pop effect and the system may include a mechanism configured to produce a haptic pop effect and a controller electronically coupled with the mechanism to selectively activate the mechanism. In one example, the mechanism has a first normal state having mechanical energy stored therein, and a second state wherein said mechanical energy is released, thereby creating the haptic pop effect. The mechanism may include a material portion configured as a dome-shaped or arcuate diaphragm and made of metal that stores mechanical energy therein. A conductor such as a Nitinol wire may be positioned about and bonded to the perimeter of the material, and has a variable length of a first length to a shorter second length in response to the signal being applied to the mechanism.
