  • RFID system for identifying location of sensors/indicators
    Patent number: 8044775
    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.

  • Design for particle sensor system
    Patent number: 7502110
    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.

  • Self-aligning, magnetically retained air sampler assembly component
    Patent number: 10712241
    Abstract: An air sampler mechanism by which the entirety of the petri plate assembly of the air sampler may be easily removed without tools is described. The mechanism employs at least one magnet which is preferably disposed within the top plate assembly of the air sampler instrument. The magnets of the mechanism are configured to maintain the top plate assembly firmly in position during use while facilitating easy removal by an operator or manager. Indexing features are preferably present, which ensure proper alignment and positioning of the top plate assembly when reattached for use.

  • FITTED FACE MASK APPARATUS
    Publication number: 20230034491
    Abstract: A face mask apparatus equipped with specially positioned fabric welds configured to ensure that the face mask contours to the shape of a user's face snugly and securely when worn. The unique weld enables the face mask to be manufactured in differing sizes without changing the fit of the fabrics employed in the construction of the mask, expediting and simplifying production. The contour established via the specific placement of the welds is aided by a foam segment on a nose bridge portion configured to provide comfort as well as a secure seal on all borders of the face mask. Three panels of varying sizes are present on each fit of the face mask.

  • Monitoring device for transport pods
    Patent number: 7605718
    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.

  • Apparatus and method for characterization of particles
    Patent number: 11846578
    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.
