摘要:
Embodiments of the present invention provide improved systems and methods for external frit mounted components on a sensor device. In one embodiment, a method for fabricating a sensor device comprises securing at least one component stack on a sensor body over at least one opening in the sensor body, wherein the at least one component stack comprises a plurality of components and applying a frit to the plurality of components in the at least one component stack and the sensor body. The method further comprises heating the frit, the at least one component stack, and the sensor body such that the frit melts and cooling the frit, the at least one component stack, and the sensor body such that the at least one component stack is secured to the sensor body.

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:
A friction surfacing apparatus and method for depositing one or more metals, metal alloys, or other materials is disclosed. The friction surfacing apparatus includes a pin tool holder, a non-consumable shoulder having an inside diameter and an outside diameter, the inside diameter terminating at an end wall and includes an angled side wall that forms a substantially frustoconical opening at one end, and a consumable pin tool coupled to the pin tool holder and at least partially protruding from the end wall of the shoulder. The shoulder is maintained at a predetermined distance from a surface of a workpiece such that the consumable pin tool deposits pin tool material onto the surface of the workpiece during a friction surfacing operation.
摘要:
A system relating to sample analyzers, and more particular, to sample analyzers that are simple to operate and have a reduced risk of providing an erroneous result to a user. In some cases, the sample analyzer may be a portable sample analyzer that includes a disposable fluidic cartridge. The operators of the analyzers need not be trained.
摘要:
An optical element for conveying scattered and image light to several detectors. The optical element may have the properties of a diffractive beam splitter and imaging lens. The detected light may be from an illuminated target. Further, there may be an optical element for conveying scattered light from a target via several zones to specific detectors, respectively. The latter optical element may include a multiple annular zone diffractive structure on a hybrid lens.
摘要:
A mechanism for moving and positioning a light source so that its light impinges a target as it moves on or off axis of an optical system. A detector may receive scattered light at a same position whether the light impinging the target is on or off axis due to, for example, a telecentric optical system. Further, the light may be positioned so that the detector is maximally impinged with scattered light. An output may go to a processor that sends a signal to the light source to move the emitted light so as to continually impinge the target as it moves on or off axis. An array of light sources may used in lieu of the moving light source. To move the light beam, another light at another position in the array may be selected to replace a previously selected light source.
摘要:
A medium having microfluidic circuitry for sampling and analyses. The medium may be a cartridge having a window countersunk into it and containing a flow channel. The flow channel may have items of interest flowing through it. Analyses of these items may be optical involving one or more light sources emanating light to and one or more light detectors receiving light from the channel. There are various configurations so that source and detector light cones may reach the flow channel without obscuration or interference of the light to and from the flow channel in the window.
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.
