  • Publication number: 20190350610
    Abstract: A tissue harvesting and wound closing device includes first and second actuator strip guides of a strip that are slideable along first and second panel guides of a panel, respectively. A first section of a base of the actuator strip has a substantially uniform width between the first and the second actuator strip guides. A second section of the base has a gradually decreasing width between the first and second actuator strip guides. A third second section of the base has a substantially uniform width between the first and second actuator strip guides that is smaller than the first width. When the actuator strip is pulled, the first and second actuator guides slide along the first and second panel guides, respectively, to cut a strip of tissue strip creating an open wound, and a panel pulls proximal tissue on opposite sides of the open wound to close the wound.

  • Publication number: 20190343343
    Abstract: Embodiments of the innovation relate to a wipe dispensing system that includes a wipe supply, a drive assembly disposed in operational communication with the wipe supply, a fluid dispensing assembly, and a wipe dispensing controller disposed in electrical communication with the drive assembly and the fluid dispensing assembly. The wipe dispensing controller is configured to receive a wipe criterion which defines a characteristic of a wipe to be provided by the wipe dispensing system, dispose a portion of the wipe supply between a first position and a second position relative to the fluid dispensing assembly via the drive assembly and based upon the wipe criterion, and apply a fluid to the portion of the wipe supply via the fluid dispensing assembly based upon the wipe criterion to generate the wipe.

  • Patent number: 9034237
    Abstract: There is provided solid imaging methods and apparatus for making three-dimensional objects from solid imaging material. A tray with a film bottom is provided to hold solid imaging material that is selectively cured into cross-sections of the three-dimensional object being built. A coater bar is moved back and forth over the film to remove any uncured solid imaging material from a previous layer and to apply a new layer of solid imaging material. A sensor is provided to measure the amount of resin in the tray to determine the appropriate amount of solid imaging material to be added, from a cartridge, for the next layer. A shuttle, which covers the tray when the exterior door to the solid imaging apparatus is opened for setting up a build or removing a three-dimensional object, can also be used to move the coater bar and to selectively open one or more valves on the cartridge to dispense the desired amount of solid imaging material.

  • Patent number: 8703037
    Abstract: A solid imaging apparatus and method employing sub-pixel shifting in multiple exposures of the digitally light projected image of a cross-section of a three-dimensional object on a solidifiable liquid medium. The multiple exposures provide increased resolution, preserving image features in a three-dimensional object and smoothing out rough or uneven edges that would otherwise be occur using digital light projectors that are limited by the number of pixels in an image projected over the size of the image. Algorithms are used to select pixels to be illuminated within the boundary of each image projected in the cross-section being exposed.

  • Patent number: 8691154
    Abstract: The presently disclosed subject matter is directed to an apparatus for the preparation of a cleaning, sanitizing, or sterilizing solution. In some embodiments, the apparatus comprises a modular component, such as a cartridge. The cartridge may contain chemical precursors to allow the generation of chlorine dioxide. The apparatus has a fluid inlet, and separates the fluid into a first flow path, which fills a reservoir. It also has a second flow path, which is heated before passing through the cartridge to create the desired gas. The fluid output from the cartridge is then fed into the reservoir.

  • Patent number: 8501061
    Abstract: A method for making a foam-in-place cushion in which a foam-forming composition is dispensed between two plastic film portions in a predetermined fashion to selectively control the distribution of the foam in the cushion. A foam dispenser can be moved in a transverse direction as foam is dispensed. A dispersion device can be employed to apply pressure on predetermined areas of the film portions towards each other so as to cause the composition to be redistributed in position in a predetermined manner while the composition is in a less than fully expanded state. The plastic film can then be sealed closed to form an expanding foam cushion that can be placed into a shipping carton where the cushion expands to fill void space, or into a mold where the cushion expands and is molded into a desired shape.

  • Patent number: 8465689
    Abstract: A solid imaging apparatus is provided that includes a replaceable cartridge containing a source of build material and an extendable and retractable flexible transport film for transporting the build material layer-by-layer from the cartridge to the surface of a build in an image plane. An operator using the device needs merely to remove a spent cartridge and replace it with a fresh cartridge to continue solid imaging virtually uninterrupted. The apparatus also includes the capability of withdrawing and inserting an imager without the operator having to perform a separate alignment step. A brush attached to the transport film and forming part of the cartridge provides for intra-layer removal of excess uncured build material. If desired, the apparatus can produce a fully reacted build. A high intensity UV source cures the build between layers. An injection molded build pad is designed to hold a build in an inverted position for improving the build.

  • Patent number: 8372459
    Abstract: An apparatus and method for cooking food, such as meat, protein, vegetable, or soup is disclosed. In one embodiment, the food items are supplied in a flexible polymer package that can withstand the temperature needed to cook the item. The cooking apparatus has two cooking surfaces in the form of heated platens, which may be arranged in a vertical orientation. These platens come together to simultaneously contact both sides of the food item. The cooking apparatus further includes a controller, configured to prepare the food using various control system algorithms. The apparatus cooks the food item from both sides to affect rapid and even cooking. It uses a combination of temperature, time, food thickness, platen force and a cooking code that is unique for each food type. The control system algorithm uses some or all of these parameters to determine precisely when the food item is cooked correctly.

  • Publication number: 20120078673
    Abstract: The present disclosure describes a dynamic queueing and management system. The system utilizes the desired completion time in determining where to place new orders into the queue of orders to be fulfilled. If the desired completion time changes, the position of the corresponding order is adjusted within the queue. In some embodiments, the desired completion time is determined based on the location of the customer, either within the store or en route to the store. The queueing and management system may also separate the order input function from the order fulfillment and delivery functions. This may optimize each part of the process and allow faster service.
