  • Patent number: 10521241
    Abstract: An added security feature on a mobile device to require an owner or an authorized user of the mobile device to provide a shutdown password to power off the mobile device is disclosed. The shutdown password is configured and set by the owner or the authorized user and stored internally in a data storage device of the mobile device. When so configured, the mobile device triggers a shutdown password input field to be displayed on the mobile device screen. The user of the mobile device must provide the shutdown password in order to power off the mobile device, thereby preventing unauthorized powering off of the mobile device and associated GPS and internal communications circuitry of the mobile device, allowing the mobile device to be tracked in the event of an emergency or when the mobile device is lost or stolen.

  • Patent number: 9188492
    Abstract: A fluid monitoring apparatus to simultaneously detect the temperature and level of fluid within a container includes a translucent tube with a proximal end, a distal end, an aperture within the wall of the tube proximate the proximal end of the tube, the distal end able to extend into the fluid container, a thermocouple secured within the tube and tethered via a wire disposable through the aperture in the tube wall, the wire including a first end secured to the thermocouple and a second end secured to a display device to display the temperature of the fluid, and a cap secured to the proximal end of the tube to create a pressure within the tube sufficient to cause the fluid that fills the distal end of the tube to remain in the tube, thereby permitting a user to determine the fluid level of the container.

  • Patent number: 6850681
    Abstract: A buffer coating for optical fibers is disclosed which includes a halogenated epoxy resin for flame-retardancy, and elastomer modified epoxy resin for tensile strength and flexibility, a low viscosity bisphenol resin for structural integrity, a viscosity modifier for improved process or extrusion properties, a polyol to increase the cure rate and cross-linking during curing, a slip agent or surfactant to reduce the adhesion of the buffer layer to the cladding and to further improve the flow characteristics during extrusion, and a photo-initiator. The buffer layer is flame-retardant and has a fast UV cure rate.
