摘要： An optical alignment system for aligning a light beam with a core flow in a flow stream. The flow stream may have a sheath fluid and a core flow, where the core flow has a current position within the flow stream. A light source may be used to produce a light beam, and an optical element may be used to direct the light beam at the core flow. In some illustrative embodiments, an actuator is provided for moving the optical element, light source and/or flow stream such that the light directed by the optical element is aligned with the current position of the core flow.

摘要： Photoacoustic cells for gas sensors are described. In some instances, the photoacoustic cell may be configured to provide an increased internal path length of the light beam in the photoacoustic cell relative to, for example, a conventional cylindrical photoacoustic cell. The photoacoustic cell may be shaped to provide increased internal reflection of the light within the photoacoustic cell, thereby increasing the absorption of the light by a gas to be detected in the photoacoustic cell. One example photoacoustic cell that can provide such increased internal reflection may be a generally conical-shaped.

摘要： An eye tracking system includes a transparent lens, at least one light source, and a plurality of light detectors. The transparent lens is adapted for disposal adjacent an eye. The at least one light source is disposed within the transparent lens and is configured to emit light toward the eye. The at least one light source is transparent to visible light. The plurality of light detectors is disposed within the transparent lens and is configured to receive light that is emitted from the at least one light source and is reflected off of the eye. Each of the light detectors is transparent to visible light and is configured, upon receipt of light that is reflected off of the eye, to supply an output signal.

摘要： Instrument-cartridge interfaces for fluidic analyzers that have an instrument and a removable cartridge are disclosed. For example, and in one illustrative embodiment, the instrument may include a needle that is adapted to penetrate a septum on a removable cartridge. In another illustrative embodiment, the instrument may include a plunger that is adapted to deform a deformable membrane on a removable cartridge. In yet another illustrative embodiment, the instrument may include a nozzle that is adapted to mate and seal with a flow channel on a removable cartridge. Techniques for detecting the flow rate in a flow channel on a removable cartridge, as well as the position of fluid in a flow channel of a removable cartridge, are also disclosed.

摘要： A method and apparatus for enabling chemical identification of individual particles, cells of molecules by obtaining a Raman spectrum of a particle, cell or molecule as it flows past a sensing point in a flow cytometer. The particles, which may be cells or molecules, are associated with a suitable noble metal colloid or colloidal aggregate. Cellular particles may be associated with gold or silver colloidal particles by ultra-sonic sonification while in a sample preparation reservoir containing the gold or silver colloidal suspension. The colloid associated particles are then hydrodynamically focused into a single file by a fluid control module. The surface-enhance Raman Spectrum of individual particles are obtained by illuminating the particle with a laser as the particle flows past a sensing point and gathering the light that is non-elastically scattered (Raman scattered) by the particle. The surface-enhanced Raman spectrum is then analyzed to identify the particle.
