Abstract: The current invention pertains to devices for counting and sizing particles suspended in a stream of fluid flowing in a predominant flow direction. Such devices comprise a fluid stream forming system having a directional element arranged to form the stream of fluid flowing in predetermined direction of fluid flow; a laser beam forming optical system including at least one source of laser light having at least one wavelength between 200 nm and 1000 nm, a profiling optical subsystem, having at least one collimator lens and at least one convergent lens, positioned to arrange the laser light in a laser beam along a laser beam axis directed substantially to illuminate a prearranged scattering volume of the stream of fluid, and at least one laser beam dump. Also, the device includes a wide-angle detecting subsystem and wide-angle back-reflecting subsystem.

Abstract: A system and apparatus for indicating a status of an instrument via visible colored light is described. Status is preferably indicated according to which color is displayed on the apparatus, which is preferably configured to illuminate on or within the handle of the instrument. Statuses may be configured by the end user, or may be pre-established according to specific uses of the instrument.

Abstract: A method and system designed to verify and protect the location-specific data acquired in measurements performed with a precise instrument is described. The system preferably employs Bluetooth radios as a means to identify distance based on signal strength, which act as beacons during measurements taken with integrated instruments. Data recorded is attributed to the precise location data acquired via the system, and is updated if movement of the measured material is performed.

Abstract: A system designed to maintain calibration and protect the location-based data acquired in measurements performed with a precise instrument. The system of the present invention is preferably implemented via an instrument that includes an RFID system. The RFID reader is preferably integrated into the measurement instrument itself, and is capable of reading RFID tags that are proximal to the instrument or are affixed to location information encoded within the RFID tags.

Abstract: A particle counter system is disclosed having a linear diverging lens, preferably a Powell lens, in order to create a top-hat profile without a loss of beam energy. The particle counter system disclosed creates ideal beam intensity distribution across the ribbon of light originating from the laser diode of the particle counter.

Abstract: A system of identifying the source location that a particle counter is using to draw its data from. The present invention includes a transmitting sensor placed at the location of interest, and a receiving sensor placed on the particle-counter device. A receiving sensor communicates a new position when a particle counter is not replaced at its origination point.

Abstract: A device that fits inside a transport pod communicating with the slots of the transport pod so that the device can be inserted and removed from the transport pod. The transport pods are for silicon wafers. The device has sensors that monitor the environment within the transport pod. Depending on the device's size, silicon wafers may be able to accompany the device so that the device can monitor the precise environment the silicon wafers are exposed to while inside the transport pod. The device may also be placed in a transport pod and run through the manufacturing process as one transport pod in a series. The results on the environmental monitoring can be used for alarms and monitoring or data logging to improve the yield of the silicon wafers.

Abstract: A system for measuring dissolved organic compounds in water that engages separate conductivity and temperature sensors at various points in the water flow. In addition, a UV reaction chamber produces light that levies high-level amounts of hydroxyl radicals during the oxidation process. The flow is then diverted into various directions based upon the settings of a three-way valve that determines when the sensor readings will take place as the water flows through the UV radiation.

Abstract: An apparatus employing a UV reaction chamber that produces light for levying high-level amounts of hydroxyl radicals during the oxidation process. The flow passes through a fluid intake and into the UV reaction chamber. A metallic coating on the outer shell and quartz reactor work for increased efficiency during the oxidation process, as does a coolant tube. The apparatus is connected to a number of conceivable systems as the apparatus aids in the rapid oxidation process of the water flow.

Abstract: A device is illustrated for detecting particles in a fluid that can detect smaller particles without the need for added power or space and can be implemented inexpensively. The device utilizes two mirrors and a photo-diode. The housing of the photo-electric diode is machined to form one of the mirrors. The mirrors have a special positioning so that the second mirror uses the first mirror to reflect light deflected by particles back to the photo-electric diode.
