Abstract: A microelectromechanical system (MEMS) sensor includes a substrate having a piezoelectric layer thereon; a MEMS piezoelectric resonator including a reference electrode on a first side of the piezoelectric layer, a first port (port 1) including a capacitor coupling electrode on a side of the piezoelectric layer opposite the first side, and a second port (port 2) for excitation signal coupling including another electrode on the side opposite the first side. The MEMS piezoelectric resonator has a natural resonant frequency. A variable capacitor on the substrate is positioned lateral to the MEMS piezoelectric resonator having a first and a second plate are connected to port 1. An antenna or an oscillator circuit is connected to port 2. Responsive to a physical parameter a capacitance of the variable capacitor changes which changes a frequency of the MEMS piezoelectric resonator relative to the natural resonant frequency to generate a frequency shift.

Abstract: A microfluidic flow restrictor that uses micron-sized beads to impede flow is described. The flow rate can be adjusted by adding or removing the beads using injection needles through self-sealing ports, one injection needle injecting or aspirating beads and another injection needle pushing or pulling fluid from outside of a bead trap within the flow restrictor. In alternative embodiments, the beads or other filler material can be trapped in a manifold bead trap such that they block a subset of fluid channels of the flow restrictor, allowing fluid to flow freely through the rest of the fluid channels. The flow restrictor can be integrated with a contact lens or implantable medical device for use in dispensing liquid therapeutic agents at flow rates of microliters per minute or moving body fluids at a controlled rate from one part of the body to another.

Abstract: A method including receiving an indication that a first classifier has identified that an image includes an object of a predetermined class of objects. Image data that relates to the image is processed using a second classifier with a first training state, which determines whether the image data includes the object of the predetermined class of objects.
