    Abstract: A lid unit for use with a beverage container. The lid unit includes a lid body having a lid cover and a side wall extending downwardly from the lid cover; and a drink straw having a gas relief valve detachably fitted to the lid body. In particular, a rotatable top plate can be placed on the lid cover; and the gas relief valve can permit the pressured gas to escape the lid unit. The gas relief valve can include a valve body, flexible strip and spool. Also, the lid cover has an annular raised rim, and defines two drink orifices. The first drink orifice is shaped and sized to be an elongated slot, and the second drink orifice is shaped and sized to be a circular hole for insertion of the drink straw. The two drink orifices are spaced apart circumferentially and in fluid communication with the beverage container.

  • Publication number: 20240150937
    Abstract: Provided herein are protective masks made with polymer-based materials and methods of forming the materials. Methods of forming the interlaced polymer-based materials comprise applying adhesive to a substrate, electrospinning a first polymer solution onto the substrate from a first group of spinning electrodes, electrospinning a second polymer solution onto the substrate from a second group of spinning electrodes, and applying hot air to dry the polymer-based materials electrospun from the first polymer solution and the second polymer solution to form the interlaced polymer-based materials.

  • Patent number: 11442501
    Abstract: An example device includes: A housing is mounted in a bezel. A camera holder is slideably mounted in the housing, the camera holder to slide in the housing between a recessed and an unrecessed position. A camera head is slideably mounted in the camera holder, the camera holder to slide between a downward position, when the camera holder is in the recessed position, and an upward position, when the camera holder is the unrecessed position. The camera head include a camera device angled outward, relative to the display, when the camera head is in the upward position and the camera holder is in the unrecessed position. The camera holder and the housing contains the camera head and the camera device, when the camera head is in the downward position and the camera holder is in the recessed position.

  • Patent number: 11330936
    Abstract: A covering member intended to be connected to a mini-oven, includes one or more connectors. The covering member is constructed and arranged to form at least a portion of the mini-oven door or to be placed between the cooking cavity and the mini-oven door when the door is closed, so as to limit access to the cooking cavity through the opening of the mini-oven. The covering member may reduce the quantity of heat energy lost from the cooking cavity when the mini-oven door is open, such that it improves the performance of the mini-oven and reduces cooking times.

  • Patent number: RE49888
    Abstract: A magnetic reader head assembly includes a magnetic reader head compartment, a frame and an elastic component. The magnetic reader head compartment comprises electronic and mechanical components of the magnetic reader head. The frame has a front side and a back side and has a footprint matching the footprint of the magnetic reader head compartment. The front side is configured to attach to a back wall of the magnetic reader head compartment while allowing the magnetic reader head compartment to move out or retract from the frame. The elastic component is configured to be placed at the back side of the frame and to push the frame out in order to press the magnetic reader head compartment against a magnetic card stripe.
