Publication number: 20200330792Abstract: The BlueGuard Antibacterial Wand was developed to address environmental pathogens control for Humans and Animals. The Antibacterial Wand is used in the name due to the mode of application of the anti-bacterial effect of the specific light wave of the Blue Light Spectrum that has been proven to be therapeutic in that it kills a wide array of Pathogens, Viruses, Fungai, Spores & Mold, and Bacteria, and is one of the many uses for this product in a single Photobiomodualation application. The Wand uses Light Emitting Diodes (LEDs) of specific wavelengths (measured in nanometers) to provide both red light for tissue and collagen re-growth, and blue light for bacteriostatic benefits together in a single unit. The Wands can be made in wide array of different shapes, designs, and sizes so it can be a hand-held source of therapeutic LED light.Type: ApplicationFiled: July 14, 2018Publication date: October 22, 2020Inventors: Patrick H.

Patent number: 8998688Abstract: An exhauster baffle is provided that may be used to prohibit fluid flow through a cavity except when a pressure on one side of the exhauster baffle is greater than a pressure on another side of the exhauster baffle. The exhauster baffle includes a body portion defining an opening, a sealer disposed on the body portion, and a flap disposed over the opening for regulating fluid flow through the opening. In one embodiment, the flap exposes the opening of the body portion to allow fluid to flow through the cavity when the pressure on one side of the exhauster baffle greater than the pressure on another side of the baffle to equalize pressure.Type: GrantFiled: October 24, 2007Date of Patent: April 7, 2015Assignee: Sika Technology AGInventors: Michael C.

Patent number: 8423207Abstract: Systems, computer program products, and methods for displaying navigation performance based flight path deviation information during the final approach segment to a runway and during landing of non-precision flight modes are provided. Improved graphical depictions of navigation performance based flight path deviation information provide pilots and flight crew members with clear, concise displays of the dynamic relationship between ANP and RNP, mode and aspect of flight and related procedures, intersecting flight paths, and current actual flight path deviation from a predefined flight path during the final approach segment to a runway and during landing. For example, an enhanced IAN display may include NPS-type deviation scales to show RNP/ANP relationships and predetermined RNP markers to alert the pilots and flight crew members that the FMC has transitioned from an NPS display for RNAV (LNAV/VNAV) flight procedures to an enhanced IAN display for a non-precision (non-xLS) approach and/or landing.Type: GrantFiled: August 26, 2011Date of Patent: April 16, 2013Assignee: The Boeing CompanyInventors: Robert B. Davis, Daniel J. Boorman, L. Kirk Gagnon, William L. Goodman, Alan R. Jacobsen, William A. Miller, James E. Mitchell, Victor A. Riley, William F. Royce, William D. Tafs

Publication number: 20040164498Abstract: The present invention is a physical barrier for an orifice in a panel member which includes a plastic carrier and a patch adapted to adhere to the carrier and the panel member. The patch is comprised of a heat-activated material. The patch is joined to a portion of the plastic carrier and encapsulates a peripheral edge of the plastic carrier. Joining the patch and the plastic carrier preferably employs use of traditional vacuum-forming techniques. The plastic carrier is attached to the panel member and the patch is heated to generally flow. The patch cools and forms a seal between the interface of the plastic carrier and the panel member while a portion of the patch is disposed between the plastic carrier and the panel member filling any gap therebetween.Type: ApplicationFiled: March 3, 2004Publication date: August 26, 2004Applicant: SIKA AUTOMOTIVEInventors: Randy Stratman, Robert B.
