Abstract:
An embodiment of the disclosure is a structure comprising an interposer. The interposer has a test structure extending along a periphery of the interposer, and at least a portion of the test structure is in a first redistribution element. The first redistribution element is on a first surface of a substrate of the interposer. The test structure is intermediate and electrically coupled to at least two probe pads.
Abstract:
An interposer includes a first surface on a first side of the interposer and a second surface on a second side of the interposer, wherein the first and the second sides are opposite sides. A first probe pad is disposed at the first surface. An electrical connector is disposed at the first surface, wherein the electrical connector is configured to be used for bonding. A through-via is disposed in the interposer. Front-side connections are disposed on the first side of the interposer, wherein the front-side connections electrically couple the through-via to the probe pad.

Abstract:
A surface-enhance Raman scattering (SERS) film is disposed on a portion of an asymmetrical optical coating of a core. The core has diameter in a range from about 10 nanometer (nm) to about 1,000 nm. The asymmetrical optical coating is in contact with a covering the core. The SERS film, the asymmetrical optical coating, and the core make up a particle. The particle is disposed on a mounting substrate.
Abstract:
An asymmetric micro pump may be adapted to provide a greater fluid compression between input and output ports of the micro pump, as well as increased flow rate due to higher actuation frequency. In some instances, asymmetric dual diaphragm micro pumps may be combined into assemblies to provide increased pressure build, improved pumping volume, or both, as desired.
Abstract:
A spectroscopic system having a coded aperture as a gating device. Light of a Raman scattering may enter the system and encounter a mask gate. The mask may have a matrix of micro mirrors some of which pass light on to a diffraction grating when the gate is on. Some of the mirrors will not pass on light thereby resulting in coded light to the grating. If the gate is off, then no light is passed on to the grating. The grating may pass the coded and spectrally spread light on to a detector array. The array signals representing the light on the array may go to a processor so one can obtain information about the target that emanated the Raman scatter when impinged by a light beam.
Abstract:
A pressure sensor having a predetermined chamber dome angle with an electrode. A hole is located in the top to provide pressure readings and the bottom has an input port. A primary diaphragm is coated on both sides with an electrode and an insulator. A secondary diaphragm is coated on the side which faces the primary diaphragm. Offset holes are made in the two diaphragms which permits pressure equalization during self calibration. Both diaphragms are initially energized to seal the gage volume, and then the secondary diaphragm is used to self calibrate using a known pressure.
Abstract:
A valve is provided that can selectively change the size of a flow channel in a valve in order to modulate the fluid flow through the valve. In one illustrative embodiment, the valve includes a housing that defines a cavity, with an inlet and an outlet extending into the cavity. A diaphragm is positioned in the cavity, where at least part of the diaphragm defines at least part of the fluid path. One or more electrodes are fixed relative to the diaphragm, and one or more electrodes are fixed relative to the housing such that the diaphragm can be electrostatically actuated to modulate the fluid flow through the valve.

In an embodiment, the invention includes a method of injection molding a stator component for an electrostatically actuated valve.
Abstract:
A method of forming an electronic part having a circuit pattern, by forming a cavity mold having trench lines in the cavity mold with a first area perpendicular to an axis and a second area having a negative slope with respect to the axis. The part is molded and removed, and a conductive material is deposited to form conductive and nonconductive areas thereon. The preferred deposit step is by blanket metallization which coats all surfaces except the sides of the trench lines and the second area of the part. The method may include the additional step of molding vertical flash portions on the part instead of or in addition to the trench lines that are removed after the conductive material is deposited thereon to form the circuit pattern.
