  • Patent number: 11302859
    Abstract: Piezoelectric elements are attractive for systems in which both sensing and actuating is required because a single element, i.e. the piezoelectric actuator, can be used that act as both a sensor and an actuator. In conventional systems combining both actuating and sensing functionality, active circuitry is required to read the sensor, and that circuitry requires static and/or dynamic current from a few microamps to a few milliamps. In systems where buttons are used a few times a day, this requirement for current leads to a significant amount of wasted power. Accordingly, a wake-up circuit is provided that does not draw power when no force is applied to the piezoelectric actuator but is capable of detecting pressure applied to the piezo actuator, generate a power-up signal to the actuating circuit, and initiate a haptic feedback with low-latency.

  • Patent number: 10646686
    Abstract: Disclosed are various embodiments providing audio frequency therapy. An audio therapy device can emit vibrations of varying frequencies. When a controller of the device is activated, the controller can transmit frequency commutations to a transducer. The transducer can emit vibrations corresponding to the frequency commutations that cause at least a first enhancer and a second enhancer to vibrate. These vibrations are then transferred to one or more parts of a human body that are in contact with pads of the device.

  • Patent number: 10598239
    Abstract: A method in which at least one piezoceramic sensor, which converts every mechanical force to which it is subjected into an electrical signal and having a Curie temperature higher than 200° C., is solidarized directly onto the surface of a metal support element of a vehicle braking element, which during use faces a vehicle element to be braked. While in contact with such a surface, an electrical circuit is implemented that picks up and eventually processes the electrical signal, the electrical circuit being connected with a connector integrated with the metal support element. An electrically insulating layer sandwiches the at least one piezoceramic sensor and the electrical circuit, and a block of friction material with an underlying damping layer is formed upon the electrically insulating layer. After forming the block of friction material, the piezoceramic sensor is polarized by applying a predetermined potential difference thereto by means of the connector.

  • Patent number: 10587971
    Abstract: A semiconductor device and its manufacturing method are presented. The manufacturing method includes providing a substrate structure; forming a first metal layer on the substrate structure; forming a second metal layer on the first metal layer; forming a first oxide layer on the second metal layer at a first temperature; and conducting the remaining manufacturing processes including thermal processes at a second temperature that is higher than the first temperature. This method reduces the concentration of the first metal diffused into the surface of the second metal layer during the thermal processes, thus reducing the amount of the oxide of the first metal formed on the surface of the second metal layer. Therefore, it is beneficial to the establishment of metal wire connections.

  • Patent number: 10567013
    Abstract: A rotary system mounted piezoelectric generator has a folded beam structure in which the whole or part of a spring is formed with a piezoelectric generation element, in which one end is provided in a drive rotation system and in which a weight is attached to the other end, the degree of freedom of motion of the weight is two or more-dimensional and thus it is possible to easily change the locus thereof. The beam has a spiral structure such that when the drive rotation system is rotated, a centrifugal force applied to the weight is efficiently modulated by a second force other than the centrifugal force. A self-powered wireless communication terminal is operated with an extremely small amount of power consumption by use of a wireless connection control means and a modulation scattering response antenna which perform multilevel phase-shift keying (MPSK).
