Patents by Inventor Mark DeWilde

Mark DeWilde has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8897458
    Abstract: An earplug which conforms to the concha of the ear and extends into the ear canal. The construction consists of a flexible outer skin with at least one filler material, preferably two or more materials of varying hardness, to form an essentially solid structure except for sound channels, or electronics packages, or other devices, parts and cavities that may be located within the flexible skin. The flexible skin can be fabricated using a rapid-prototyping printing process.
    Type: Grant
    Filed: March 26, 2012
    Date of Patent: November 25, 2014
    Assignee: Red Tail Hawk Corporation
    Inventors: John W. Parkins, Mark DeWilde
  • Patent number: 8498440
    Abstract: An eartip made of a resilient body with an eartip core inside the open center of the body, and a tether attached to the eartip core at an attachment region along the length of the core. A free end of the tether extends outward from the eartip, allowing a wearer to remove the eartip from their ear by pulling on the tether.

  • Patent number: 6571302
    Abstract: The present invention provides a high speed, multi-ported, direct data flow memory architecture that employs memory width and speed greater than system bus width and speed to allow shallow burst depth and reduce other-port latencies, while maintaining multi-port throughput. The inventive system has a data storage device (SDRAM) and a multiplexer connected to the SDRAM. Two or more interfaces or ports are provided with data sourcing controllers respectively connected to the interfaces. A communications bus connects the SDRAM to the data sourcing controllers for facilitating data communications. A FIFO buffer memory is located between the multiplexer and the data sourcing controllers. The need for retries is eliminated and host bus widths are matched to memory data width. Read-ahead algorithms are provided that adapt the larger system bus burst sizes to the smaller memory burst sizes with the ability to cancel unneeded advance requests for data.
