An analytical system includes a laser disposed to direct light toward a microfluidic feature disposed in a feature layer of a multiple layer test cartridge, a sensor to receive reflections from capping layers disposed about the microfluidic feature in the feature layer, and a controller to determine a depth of the microfluidic feature as a function of the received reflections.

Method to calibrate disposable cartridge cuvette thickness in-situ

A disposable blood analysis cartridge for analyzing a blood sample including an optical absorbance measurement channel is described. The optical absorbance measurement channel includes a plasma separation region and at least one sub channel including a cuvette that is in fluid communication with the plasma separation region and configured to receive a plasma portion of a blood sample that has been passed through the plasma separation region. A negative pressure may be applied to the cartridge to draw the sample through the plasma separation region and into the sub channel including the cuvette.

Disposable cartridge for fluid analysis

A disposable blood analysis cartridge for analyzing a blood sample including an optical light scattering measurement channel is described. In use, processed sample may be introduced into a sheath fluid channel at an angle, &#x3b1;, of approximately 90 degrees, relative to the direction of flow of the sheath fluid. In addition, delivering the sample from the side into the sheath fluid may facilitate better positioning of the core within the hydrodynamic focusing channel for measurement.

The present invention relates to electrostatically actuated device components and methods of making the same. In an embodiment, the invention includes a method of making an electrostatically actuated device component including providing a multilayered structure comprising a first layer comprising a first polymer, a second layer comprising a conductive material, the second layer disposed over the first layer, a third layer comprising a dielectric material, the third layer disposed over the second layer, positioning the multilayered structure within an injection mold, and injecting a second polymer into the mold and bonding the first layer to the second polymer to produce an electrostatically actuated device component. In an embodiment, the invention includes a method of injection molding a stator component for an electrostatically actuated valve.

Insert molded actuator components

An apparatus for assembling an electronic device is disclosed, which includes one or more grid holders for maintaining one or more grids in association with a plurality of conducting components positioned perpendicular to the grid(s). One or more insulating components are also provided for mounting and supporting the conducting components. The grid holder(s) can be pushed onto the conducting components in order to eliminate the need for applying spot weld currents to the conducting components and thereby provide a weldless assembly apparatus for the precise construction of an electronic device.

A VCSEL includes a substrate having a partially removed portion; a metal-assisted DBR having a metal layer and a first mirror stack, wherein the metal layer is located at the partially removed portion of the substrate; an active region having a plurality of quantum wells over the metal-assisted DBR; and a second mirror stack over the active region, wherein a number of alternating layers of the first mirror stack is substantially smaller than a number typically required for a VCSEL without the integrated metal reflector. Such a metal-assisted DBR is especially useful for a long-wavelength VCSEL on a InP substrate or a red-color VCSEL on a GaAs substrate.

A vertical cavity surface emitting laser (VCSEL) includes independently definable current and optical confinement structures that provide unique forms of drive current and transverse mode confinement, respectively. The optical guide may be formed from an upper distributed Bragg reflector (DBR), as an etched mesa structure and/or as an intracavity optical guide. The current guide may include an ion-implanted region within the upper DBR. A dielectric structure is formed over the upper DBR and surrounds the optical guide.

A pressure sensor includes a housing portion with a fluid inlet and a polymer element within the housing portion. The polymer element may be coated with piezoresistive material to form a first resistor and may have associated electrodes. The polymer element includes a first resistance value that changes to a second resistive value in a response to a predetermined condition. The pressure sensor may also include a second polymer element that includes a first resistance value that changes to a second resistive value in a response to a predetermined condition.

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.

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.

A long wavelength vertical cavity surface emitting laser having a substrate, a first mirror situated on the substrate, an active region situated on the first mirror, a second mirror situated on the active region. The first mirror may have several pairs of layers with an oxidized layer in one or more pairs of that mirror. The substrate may include InP and the mirror components may be compatible with the InP. The one or more layers in the first mirror may be oxidized via a trench-like approach or other arrangement.

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.

A vertical cavity surface emitting laser (VCSEL) structure includes a bottom distributed Bragg reflector (DBR) arranged over a substrate; a metal layer interposed between the bottom DBR and the substrate, wherein the metal layer and bottom DBR form a composite mirror structure. A patterned dielectric layer may be interposed between the metal layer and the bottom DBR to reduce a deleterious chemical reaction between the metal layer and the bottom DBR. The metal layer directly contacts a portion of the bottom DBR to enhance the electrical and thermal conductivity of the VCSEL structure.
