Patent number: 11812898Abstract: A portable towel dispensing device for carrying the paper towel dispenser by an attachable strap includes a tube. The tube has an end and an opposite end. A solid end is coupled to the end and a cap end is positioned on the opposite end. The cap end can be removable from the tube to expose a hollow interior to the user. A roll of paper towels is contained within the hollow interior. A plurality of belt clips is coupled to an exterior of the tube. Each of the belt clips has an aperture. A strap has a pair of ends with a hook clip coupled to each of the ends. Each of the hook clips attaches to the aperture of each of the belt clips. The strap is positioned on the shoulder or the waist of the user.Type: GrantFiled: February 15, 2022Date of Patent: November 14, 2023Inventor: Dwayne Campbell

Patent number: 11724121Abstract: Disorders of the eye can be treated by photobiomodulation therapy according to a device designed to direct light into a patient's eye, no matter the configuration of the eye. The device, including a printed circuit board that includes an array of light delivery devices and a heat sink lens, can be placed proximal to the patient's eye. The light delivery devices can be powered to generate light. The light can be directed into the patient's eye regardless of a position of the patient's eye.Type: GrantFiled: July 23, 2020Date of Patent: August 15, 2023Assignee: MEDICAL QUANT USAInventors: Douglas Johnson, Max Kanarsky, Larry W. Finn, Ian Dwayne Campbell, Jeffrey A. Lenk, Michael T. Barrett, Scott R. Lenk

Patent number: 11638833Abstract: Disorders of the eye can be treated by photobiomodulation therapy (PBMT) delivered by a PBMT device. The PBMT device can be configured for placement directly over a patient's eye socket to deliver light into the patient's eye regardless of a position of the patient's eye, while preventing blue light from entering the patient's eye (e.g., due to a filter within the PBMT device and/or an opacity of the housing of the PBMT device). The PBMT device can be powered by a controller.Type: GrantFiled: July 23, 2020Date of Patent: May 2, 2023Assignee: MULTI RADIANCE MEDICALInventors: Douglas Johnson, Max Kanarsky, Larry W. Finn, Ian Dwayne Campbell, Jeffrey A. Lenk, Michael T. Barrett, Scott R. Lenk

Patent number: 8212376Abstract: An apparatus, and an associated method, for powering a powerline network apparatus, such as a HOMEPLUG™ transceiver. A data signal sensor is positioned to sense a data signal that is to be operated upon by the powerline network apparatus. When a data signal is sensed, an indication is formed, and the indication is used to control the switch positioning of a switch that interconnects a power supply with the powerline network apparatus. When the indication of sensing of the data signal is formed, the switch is closed, and the power supply is connected to the powerline-network apparatus operative power is provided to power the powerline network apparatus.Type: GrantFiled: November 14, 2008Date of Patent: July 3, 2012Assignee: RadioShack CorporationInventors: Peter Griffin, Dwayne Campbell

Patent number: 7171308Abstract: A weather station for providing weather information to a user, especially weather information related to lightning and severe thunderstorm activity. In accordance with the present invention, the weather station includes one or more antennas for receiving GPS transmissions, weather radio transmissions, and a separate radio band, such as the AM radio band for use in detecting lightning strikes. The GPS signal is used to determine the position of the user. A lightning detector coupled to the antenna for receiving the AM (or other band) signal calculates the proximity of any detected lightning strikes. The national weather radio band antenna receives information from NOAA and similar organizations and presents it to the user in the normal fashion.Type: GrantFiled: October 29, 2004Date of Patent: January 30, 2007Assignee: Radio Shack CorporationInventor: Dwayne Campbell

Patent number: 6684174Abstract: A wind gauge apparatus and method. An illustrative embodiment includes a microphone positioned to engage wind pressure from a first relative direction and a controller coupled to receive an audio signal from the microphone. The controller compares the audio signal with plural threshold values, representative of wind pressure levels, and determines a first wind pressure level incident upon the microphone. Filtering and gain controls are used to condition the audio signal output from the microphone. Plural microphones are employed to allow that detection of wind direction and magnitude about a compass of directions. Digital signal processing is employed to process data. In an illustrative embodiment, the wind direction and magnitude data are used to recommend a golf club size adjustment and a golf swing direction adjustment to the user, who has taken a measurement of the wind with respect to a reference golf swing direction.Type: GrantFiled: February 27, 2002Date of Patent: January 27, 2004Assignee: RadioShack, Corp.Inventors: John M. Clark, Ian Dwayne Campbell, Watson C. K. Chow, David J. Edmondson, Marco C. Ko, Alan M. L. Lam, Vincent M. T. Lam, Wai-Fong Lee
