  • Noise management system, a window system and related methods
    Patent number: 11393445
    Abstract: A noise management system for a window includes an active noise control (ANC) module and a passive sound absorbing module. The ANC module is disposed in or adjacent a ventilation channel of the window and configured to substantially cancel low-frequency noise entering the ventilation channel. The passive sound absorbing module is disposed in or adjacent to the ventilation channel and configured to absorb both high-frequency noise entering the channel and harmonic sounds generated by the ANC module.
    Type: Grant
    Filed: August 23, 2019
    Date of Patent: July 19, 2022

  • Fluid jet dispenser using multilayer ceramic actuators
    Patent number: 11161125
    Abstract: A fluid jet dispenser using at least two multilayer piezoelectric actuators is provided. The fluid jet dispenser includes a dispensing head and an electrical driver. The dispensing head includes at least two d31-mode multilayer piezoelectric actuators, a displacement magnifying element mechanically coupled to the d31-mode multilayer piezoelectric actuators, a piston, and a nozzle. More preferably, the two d31-mode multilayer piezoelectric actuators operate in an anti-phase condition. The electrical driver is electrically coupled to the d31-mode multilayer piezoelectric actuators for displacing the actuators in directions substantially perpendicular to polarization of piezoelectric layers in the d31-mode multilayer piezoelectric actuators in response to charging and discharging of the actuators by the electrical driver, to generate a fast movement of the piston to jet a pressurized fluid out of the nozzle of the dispensing head.
