Abstract: A method and system teaches unique applications of logic and statistics to medical processes to obtain substantially improved accuracy in the measurement of a examinee's pathology due to an injury. The method and the system incorporate strict protocols, or “Administrative Rule Sets” to direct the examination for the purpose of obtaining an optimal data set, from which a rating of the impairment due to the pathology resulting from an injury may be determined. Additionally, within this method and system, a statistical analysis may additionally assist in obtaining an improved accuracy of impairment ratings. Consequently, the errors in the impairment rating presently carried forward through the disability, care and compensation phases of the process are now avoided.

Abstract: Early stage, rapid, low-cost detection of disease components in a biological sample is critically important. A point of care device can include a collection region and can be used to hold a sample that is combined with a fluorescent dye and a plurality of magnetic particles such that disease components in the sample are tagged with the fluorescent dye and the plurality of magnetic particles. At least one magnet can be located next to the collection region to establish a magnetic field gradient to draw the tagged disease components into the collection region from the device. A fluorescence microscope can image the small collection region based on the fluorescent dye to detect the disease components. The fluorescence microscope uses light to excite the fluorescent dye and a filter to transmit light emitted by the fluorescent dye to the fluorescence microscope, while restricting light used to excite the fluorescent dye.

Abstract: A diagnostic device is described herein that can be used to perform magneto-optical detection and discernment of crystals within a biofluid sample. A magnetic field can be applied by the diagnostic device in a direction relative to light traveling through the sample. The presence of a crystal can be determined based on the magneto-optical properties of the sample. The detected crystal can be one of two similar crystal types that may be in the biofluid sample. The two similar crystal types can exhibit different magneto-optical properties under a magnetic field in a different direction. Accordingly, the type of crystal can be discerned by applying the magnetic field in the different direction as light travels through the sample. Discernment of the type of crystal can lead to diagnosis of the particular disease condition and subsequent proper treatment of the disease condition.

The intermediate region includes a primary deflecting surface, and a secondary deflecting surface that is surrounded by the primary deflecting surface. The deflector member provides for generation of a non-circular spray pattern defined by four zones of fluid density concentrically formed about the sprinkler axis.

Abstract: A bracket presenter for an ultrasonic welder includes a one-piece first bracket portion and a one-piece second bracket portion mounted relative to one another. First and second tapered features are respectively provided by the first and second bracket portions and are nested relative to one another. The first and second tapered features engage in an extended position and are spaced from one another in a compressed position to provide a clearance enabling the first and second bracket portions to float lateral relative to one another. A spring biases the first and second bracket portions apart.

Abstract: An electric drive system includes a controller and an inverter having a switch and a current sensor. The controller reduces power output of the inverter while a sensed temperature of the switch, a sensed current from the inverter, and parameter values of the current sensor are indicative of a predicted temperature of the current sensor being greater than a threshold to maintain inverter temperature lower than the threshold. The parameter values are obtainable from a thermal model of the current sensor. The thermal model is derived from testing a test version of the inverter under different drive cycles in which for each drive cycle a set of information is recorded including a sensed temperature of a switch of the inverter test version, a sensed current output from the inverter test version, and a sensed temperature of a current sensor of the inverter test version.

Abstract: Automated tray handling systems and methods may include robotic systems having various end effectors to move trays relative to item sortation systems. For example, the robotic systems may include robotic arms and gantry systems. In addition, the various end effectors may include dual end effectors and passthrough end effectors. The dual end effectors may lift, move, and place trays by engaging and clamping onto flanges of the trays. The passthrough end effectors may lift, move, and place trays through an interior of the end effectors by engaging and pulling or pushing flanges, edges, or other surfaces of the trays. The various automated tray handling systems and methods may increase the speed and efficiency of such processes while also reducing or minimizing the space required for such systems.
