  • Patent number: 12385815
    Abstract: Various examples of systems and methods are provided for slide processing. In one example, among others, a system for processing microscope slides includes a slide positioner that can adjust a position of a slide and a slide treatment system that can dispense a micro stream of a fluid at a location on the slide when the slide is positioned beneath a jet nozzle of the slide treatment system. The system can include a slide sled that can align a smearing slide with a surface of the slide including a fluid sample is disposed, and support the smearing slide at a predefined angle with respect to the surface of the slide. In another example, a method includes obtaining a slide including a sample disposed on a surface, positioning the slide below to a jet nozzle, and dispensing a micro stream of a fluid onto the sample using the jet nozzle.

  • Patent number: 12299917
    Abstract: Various examples of systems and methods are provided for imaging calibration for slide processing. In one example, among others, a system for processing microscope slides includes a light source; an imaging device comprising a lens; and a slide positioner that can position the ground-glass portion of a slide between the light source and lens. Processing circuitry of the system can acquire an image of at least a section of the ground-glass portion at an initial position; analyze contrast of adjacent pixels with respect to a defined contrast characteristic; iteratively advance the lens and acquire additional images based upon analysis of contrast of adjacent pixels with respect to the defined contrast characteristic; and identify an optimal focal location of the lens based upon the defined contrast characteristic. Subsequent image acquisition via the lens can be based at least in part upon the optimal focal location.

  • Patent number: 11382661
    Abstract: Methods, apparatuses and systems are described for implanting a plurality of fiducial markers into a tissue. Systems include a needle, a stylet sized to slide within a lumen of the needle, and a multi-stop stylet spacer having stopping features configured to engage with the stylet to stop the distal end of the stylet at one or more predetermined distances from the distal end of the needle. Methods for implanting a plurality of fiducial markers into a tissue are described and include inserting a needle preloaded with fiducial markers into a tissue, adjusting a multi-stop stylet spacer from a safety position to a first deployment position, deploying a first fiducial marker into the tissue, adjusting the stylet spacer from the first deployment position to a second deployment position, and deploying a second fiducial marker into the tissue.

  • Patent number: 10842213
    Abstract: The purpose of this process is to remove the human contact of fabric in assembling products and producing clothing faster without several stations of production in different locations in the factor. In the past, a typical factor would sew individual pieces at one station and pass them along to different stages in the assembly process until its completed. However, this process is meant to eliminate it, improve efficiency, and productivity. This process will not include any human contact with fabric, less time in production, and the removal of products in different stations. The benefits of this enable a company to produce what they need as needed, instead of producing a factor's minimum. Furthermore, this process shortens the lead time to bring products to market faster. Finally, this process helps with cash-flow, which is essential in any business especially in manufacturing.

  • Patent number: 10758213
    Abstract: The present disclosure generally relates to a biopsy needle configured to maximize tissue sampling yield and collect a unit of sampled tissue. The biopsy needle includes an elongate tubular body comprising a lumen extending therethrough from a proximal open end to a distal open end of the body. The distal end includes first and second tip portions extending therefrom and formed on opposing sides of the needle body. The first tip portion generally extends further from the distal end than the second tip portion, resembling a staggered configuration, resulting in an increased surface area of multiple cutting edges formed between the first and second tip portions on either side of the needle body. Additionally, each of the tip portion defines a penetrating point configured to pierce the tissue to be sampled and direct sampled tissue towards the lumen of the body to be excised by the cutting edges.

  • Patent number: 10512288
    Abstract: Disclosed is a male undergarment that has an expandable pouch. The pouch expands as needed depending on the male's genitalia. The pouch has a horizontal elastic band one and two-third inches below the garment's waistband which enables the pouch to adjust as needed. This horizontal elastic band is to be a half an inch long and one cm width depending on the size of the pouch. This pouch also has a four technique fold of material to increase comfort in the pouch. The two components combined creates a pouch that expands to the male's need.

  • Patent number: 10182798
    Abstract: The present disclosure provides an adjustable delivery handle system for interchangeably delivering a needle to a biopsy site. The adjustable delivery handle system includes a delivery handle having an inner hub housing component configured to interchangeably receive a needle subassembly that can be inserted into and withdrawn from the proximal handle member. The needle subassembly includes a biopsy needle having a distinct tissue collection distal end configured to maximize tissue sampling yield and collect a cohesive unit of sampled tissue. The distal end of the needle includes first and second tip portions extending therefrom and radially opposing one another. The first tip portion has a length greater than the second tip portion, thereby resulting in an increased surface area of a curvilinear cutting edge extending from the first tip portion to the second tip portion.
