  • Patent number: 9995718
    Abstract: The electrostatic sensors of bridge or cantilever type with multiple electrodes, the electrostatic sensors of comb type and piezoelectric sensors are used for the single molecule detection of ligands. The electrical driving of sensors is separated in some cases from the sensing for increased sensitivity. The large arrays of sensors with individual or common sensing circuits are employed to further improve detection sensitivity. The fabrication of the sensors, their functionalization for detection of many chemical and biological species and electrical circuitry, packaging, microfluidic subsystem and the system architecture are also disclosed. The individual, specific sensing of single species or simultaneous detection of multiple species is realized. The freeze drying or critical point drying after exposure of sensors to ligands present in liquids and detection in reduced pressure or vacuum is employed for increased sensitivity, down to the single molecule.

  • Patent number: 9956356
    Abstract: A nebulizer has an aperture plate, a mounting, an actuator, and an aperture plate drive circuit (2-4). A controller measures an electrical drive parameter at each of a plurality of measuring points, each measuring point having a drive frequency; and based on the values of the parameter at the measuring points makes a determination of optimum drive frequency and also an end-of-dose prediction. The controller performs a short scan at regular sub-second intervals at which drive current is measured at two measuring points with different drive frequencies. According to drive parameter measurements at these points the controller determines if a full scan sweeping across a larger number of measuring points should be performed. The full scan provides the optimum drive frequency for the device and also an end of dose indication.

  • Patent number: 9933394
    Abstract: A method is disclosed for testing for delamination of a first composite component from a second composite component a composite material. The method comprises coupling a broad-band actuator to the composite material and connecting sweeping frequencies to the broad-band actuator for vibrating the composite material. An acoustic sensor is coupled to the composite material for measuring a resonant frequency curve of the vibrating composite material. The measured resonant frequency curve of the vibrating composite material is compared with a reference resonant frequency curve. A delaminated composite material produces a change in the measured resonant frequency curve relative to the reference resonant frequency curve. The method is suitable for detecting delamination in fuel cells as well as ceramic body armor.

  • Patent number: 9921057
    Abstract: Methods, systems and device are provided for improving the range and accuracy of proximity measurement such as in ultrasonic sensing systems. In particular, the blind zone caused by reverberation signals can be reduced or eliminated by attenuating signals received during the time period corresponding to the blind zone without. In an implementation, an attenuator circuit is selected by a switch to process received signals during the blind zone time period and deselected by the switch after the time zone time period. Additionally, the accuracy and range of the measurement can be improved by varying the gain provided to the received signals based on the varying measuring distance. In an implementation, a gain-adjustable amplifier is controlled by a gain control signal to provide incremental gain as time increases.

  • Patent number: 9874842
    Abstract: A protection member is arranged such that the distance from an opening plane of a reception guide to the center of the protection member is half of the distance from the opening plane of the reception guide to the surface of a reception vibration member. In other words, the arrangement position of the protection member is in the center between the opening plane of the reception guide and the surface of the reception vibration member. Accordingly, even if a protection member is arranged, a transmission coefficient is obtained that is equal to a transmission coefficient in the case where no protection member is present.
