  • Publication number: 20200260885
    Abstract: A duvet cover system having customizable variable performance includes a cover layer and a duvet insert received in a pocket of the cover layer. The duvet insert includes first and second insert portions that may be removably connected to one another along a junction such that the insert portions cover different sides of the bed when the system is spread over the bed. The first insert portion defines at least two quantifiable performance factors including a first thermal retention value and a first air permeability value, and the second insert portion defines at least two quantifiable performance factors in a similar manner. However, these quantifiable performance factors of the first and second insert portions are different from one another to provide the different sleep experiences desired by users on opposite sides of the bed. The system still provides the desired appearance of a conventional duvet when fully assembled.

  • Patent number: 10413099
    Abstract: A simulated duvet cover system provides an easily-manufactured and assembled construction in which a cover layer, defined by top and bottom fabric sheets with pockets defined therebetween, is configured to be removably coupled to a separate fill layer, defined by a blanket or comforter. The bottom fabric sheet extends inwardly from the periphery of the top fabric sheet to surround a central opening, which the fill layer can be inserted through and then tucked into the pockets. A further backing layer may be connected to the cover layer with non-metallic and non-rigid fasteners such as fabric knot buttons, to cover the central opening. The system hides the appearance of the fill layer when in use, thereby providing a similar appearance to a conventional duvet cover, while still allowing for easy removal and cleaning of the system with industrial laundering equipment or the like.

  • Publication number: 20190166930
    Abstract: A personal protective equipment (PPE) rear opening isolation gown is provided that can be used by workers in the healthcare industry. The isolation gown is reusable and can provide for ease of doffing, such as in a pull forward manner that is consistent with how current users of disposable isolation gowns are accustomed to removing such gowns, without substantial risk of damaging (e.g., tearing) the gown and without substantial risk of the transfer of potentially harmful microorganisms, body fluids, and/or particulate material, to the neck or hair on the head or neck of a wearer. The reusable, rear opening isolation gown is provided with an easy release fastener(s) that provides a safe and secure hold when fastened but permits the gown to be removed easily, quickly, and more safely than other reusable options.

  • Patent number: 10296069
    Abstract: Systems, methods, and computer programs are disclosed for reducing dynamic random access memory (DRAM) power consumption within a selected voltage frequency/bin. One embodiment is a method comprising receiving a selected voltage/frequency bin for operating a memory bus electrically coupling a memory controller to a dynamic random access memory (DRAM). The method monitors a bandwidth of the memory bus while operating at the selected voltage/frequency bin. The method frequency switches a clock for the memory bus, based on the monitored bandwidth, between a plurality of predefined frequencies within the selected voltage/frequency bin to maintain a target bandwidth.

  • Patent number: 10285517
    Abstract: A simulated duvet cover system provides an easily-assembled multi-layer construction in which first and second cover layers formed by fabric sheets are removably coupled to an intermediate layer defined by a blanket or comforter and sandwiched between the cover layers. Each of the first and second cover layers is separately coupled to the intermediate layer using respective first and second fastening elements, which may include snaps, hook and loop fasteners, magnets, and the like. The coupling may be limited to being at the corner portions and along one of four side/end edges of the layers to promote quick and easy removal of the cover layers when those require cleaning. The cover layers are sized such that portions of these cover layers overlie or cover up the fastening elements when the cover system is assembled on a bed, thereby providing a similar appearance to a conventional duvet cover.

  • Publication number: 20190099020
    Abstract: An adjustable height bed skirt is provided for covering a gap defined between a mattress of a bed and a floor surface upon which the bed sits. The bed skirt includes a decking panel with a plurality of fastening strips spaced-apart from one another and extending along the bottom edge and side edges of the decking panel. A skirt panel includes a fastening strip that can be removably coupled to one of the plurality of fastening strips on the decking panel to adjust a vertical drop height that the skirt panel covers as it extends along three sides of the bed. The skirt panel includes corner pleats and the decking panel includes bottom corner portions, each of which do not include the fastening strips. Additionally, color-coded indicia elements are applied to the fastening strips on the decking panel to assist with connecting the skirt panel in the desired position.

  • Publication number: 20180335828
    Abstract: Systems and methods are disclosed for reducing double data rate (DDR) memory power consumption via device-specific customization of DDR interface parameters. One embodiment comprises a method for minimizing double data rate (DDR) power consumption. The method selects one of a plurality of operating points for a DDR interface electrically coupling a DDR memory to a memory controller residing on a system on chip (SoC). The memory controller executes a memory test via the DDR interface at the selected operating point. During the execution of the memory test at the selected operating point, the method determines an optimal value of a setting for one or more DDR interface parameters associated with the DDR interface that minimizes memory power consumption and maintains a predetermined DDR eye margin.
