  • Publication number: 20200025305
    Abstract: A system for regulating fluid flow having a processor configured to reduce image noise is provided. The system includes an image sensor to capture an image of the drip chamber and a valve to regulate the fluid flowing from the drip chamber to a patient. The processor captures the image of the drip chamber using the image sensor, performs an edge detection on the image to generate a first processed image, and performs an AND-operation on a pixel on a first side of an axis of the first processed image with a corresponding mirror pixel on a second side of the axis of the first processed image to generate a second processed image.

  • Patent number: 10481116
    Abstract: A nondestructive system and method for high resolution thermal imaging in metal casting applications is provided to detect defects and starts with the article under test being subjected to a thermal gradient, followed by infrared images taken thereof. The creation of the thermal gradient results in any defects reacting differently to the thermal gradient application to accentuate the defect in the infrared image. The apparatus for conducting the tests in one embodiment includes a single channel sensor, remote cable, and a laptop controller with real time image processing software. This hardware provides high resolution, real-time viewable infrared (IR) images with a variable focus distance adjustable from six inches to infinity. The apparatus enables crisp, clear imagery of various metal casting defects.

  • Patent number: 10436342
    Abstract: A flow meter, and related method, include a coupler adapted to couple to a drip chamber, a support member operatively coupled to the coupler, an image sensor and a backlight. The image sensor has a field of view and is operatively coupled to the support member. The backlight is adapted to illuminate the image sensor to expose the image sensor such that the field of view of the image sensor at least partially images at least a portion of the drip chamber. A processor receives image data from the image sensor to select a region of interest of the image sensor, determine whether a pixel of the image sensor is within the region of interest, activate the at least one light of the backlight when the pixel of the image sensor is within the region of interest, and expose the pixel of the image sensor.

  • Publication number: 20190249657
    Abstract: A peristaltic pump and related-method are disclosed that includes a cam shaft having a plunger cam, a plunger-cam follower that engages the plunger cam of the cam shaft, a tube receiver, a spring, a plunger, a position sensor, and a processor. The tube receiver receives a tube. The spring provides a bias. The plunger is biased toward the tube by the spring and the plunger is to the plunger-cam follower, such that expansion of the plunger cam along a radial angle intersecting the plunger-cam follower as the cam shaft rotates actuates the plunger away from the tube. The position sensor determines a position of the plunger and the processor estimates fluid flow within the tube utilizing the position of the plunger.

  • Publication number: 20190134298
    Abstract: A pump includes a reservoir, a port, and a plunger. The reservoir delivers a liquid by discharging the liquid through the port coupled to the reservoir. A piston of the plunger defines a liquid side of the reservoir and a non-liquid side of the reservoir whereby movement of the plunger towards the liquid side of the reservoir discharges liquid through the port. The pump also includes a reference-volume assembly and/or a linear position sensor. The reference-volume assembly is coupled to the reservoir at an opposite end of the reservoir relative to the port and includes a reference-volume chamber in acoustic communication with the non-liquid side of the reservoir, a speaker disposed within the reference-volume chamber, and a reference microphone disposed within the reference-volume chamber. The pump estimate the amount of liquid discharged from the reservoir.

  • Patent number: 7270299
    Abstract: A new approach for designing satellite constellations whereby each satellite follows a common ground track is being proposed for performing high-precision change detection imagery for long periods of time. By precisely prescribing the orbital parameters, i.e., the relationship between the right ascension of the ascending nodes (RAAN) and the phase angle difference between successive satellites, for example, sharpened change detection images may be taken from successive satellites in the constellation without the need to process out blurring by any special image re-working software. The relationship between the orbital parameters of the satellites is precisely tuned to the earth's rotation rate for the altitude of the satellites. A reduction in the total satellite count is achievable due to tiling the satellite coverage in near optimal arrangements.

  • Patent number: 7258305
    Abstract: A new approach for designing satellite constellations whereby the satellites are distributed into contiguous groups forming longitudinal lengths at least equal to 360 degrees. Gaps between the contiguous groups are uniformly distributed along the tracks. These contiguous groups of satellites may be populated by having multiple satellites onboard a single launch vehicle, whereby the satellites are nested into multiple common ground track sub-constellations to form a constellation with multiple common ground tracks.

  • Patent number: 7255308
    Abstract: A new method of constellation design based on combining repeating ground tracks with common ground tracks and/or sun-synchronous orbits is used for performing high-precision change detection imagery for longer periods of time while minimizing battery usage. By precisely prescribing the orbital parameters, sharpened change detection images may be taken without the need to process out blurring by any special image re-working software. The relationship between the orbital parameters of the satellites is precisely tuned to the earth's rotation rate for the altitude of the satellites. The unique set of earth orbits minimizes satellite battery requirement while optimizing the ability to perform coherent change detection (CCD).

  • Patent number: 5955987
    Abstract: A radio frequency navigation receiver has analog and digital sections. In the analog section, a CRPA antenna module receives global navigation signals and provides two steerable nulls for jammer suppression. An analog RF module has an amplifier and a YIG filter for amplifying and filtering an antenna output signal with jammer suppression. An analog receiver receives and downconverts an RF output signal from the RF system with additional jammer suppression. The analog receiver provides broadband signal filtering with at least 30 dB rejection and narrow band signal filtering with at least 45 dB rejection.In the digital section, a digital receiver module receives and converts an analog receiver output signal to generate a digital output signal for navigation control. A configuration manager processor responds to detected jammer signals to configure the receiver modules accordingly.
