摘要： A fluidic device and a method of preventing isolation material from bleed-out therein is described herein. The fluidic device includes a bulk acoustic wave resonator structure defining at least one surface area region on which a functionalization material is disposed and the resonator structure includes a repelling area. The fluidic device also includes isolation material disposed on the resonator structure and away from the at least one surface area region. The repelling area is configured to prevent the isolation material from extending into the at least one surface area region. Further, an electronic board may be operably attached to the resonator structure and the isolation material may be disposed in a gap therebetween to electrically isolate electrical contacts and form a fluidic channel.

摘要： A sensor includes a first element part having a first member and a first element. The first member is a acoustic tubular waveguide and extends along a first direction. The acoustic tubular waveguide includes a first opening and a second opening. A direction from the second opening toward the first opening is along the first direction. The first element includes a vibratile first membrane, and a first supporter supporting the first membrane. The second opening is between the first opening and the first membrane in the first direction. The sensor may be a Piezoelectric Micro electro mechanical systems Ultrasonic Transducer and may be used for inspecting paper and/or resin including detecting thickness of a fed through banknote and/or the presence of foreign matter thereon such as tape. An optical element may alternatively measure the vibration of a membrane from acoustic through transmission instead of an acoustic receiver.

摘要： A methods and systems for determining a change in condition of a rock bolt. Some methods may comprise, at a first point in time, propagating shear and longitudinal ultrasonic waves along the rock bolt to measure a first time of flight for each of the shear and longitudinal waves, at a second point in time after the first point in time, propagating shear and longitudinal ultrasonic waves along the rock bolt to measure a second time of flight for each of the shear and longitudinal waves, and using the relative changes of the first and second time of flights, determining the change in condition of the rock bolt section.
