Abstract: Radiation shielding performs a range of functions determined by the type and number of layers of materials used, thickness, weight, and structural support afforded by the radiation shielding. A radiation shield laminate stack may be constructed consisting of a plurality of layers of ultra-high molecular weight (UHMW) polyethylene, polyethylene film, and carbon fiber, which is held together with an epoxy. The carbon fiber lay may be coated with nanoparticles of Boron (B) or Boron Nitride (BN), Boron Oxide (B2O3) or Boron Carbide (B4C) or a combination thereof to increase the shielding properties of the laminate stack. The radiation shield is lighter than aluminum, structurally sound, and thus may be used in the space environment to effectively block Galactic Cosmic Rays, atomic oxygen and UV radiation.

Abstract: A solution for providing laser mode hop detection in hard disk drives can include a first circuit to provide a signal having a step voltage whose amplitude is adjustable according to a first control signal. The solution can include a second circuit causing the signal to be delayed by a time period to produce a delayed signal, the time period adjustable according to a second control signal. The solution can include a filter to receive the delayed signal as input and provide as output an offset signal corresponding to a frequency response a sensor. The system can subtract the offset signal from a sensor signal of a sensor to provide an output.

Abstract: A solution can detect an HDD laser mode hop within an improved response time using a sensor amplification circuitry balanced by a frequency response of a gain stage circuit. A sensor of a first circuit can receive an optical signal of a laser as input and output a first voltage that an amplifier can amplify to produce an amplified first voltage indicative of a mode hop event trailing the optical signal by a first response time of a first frequency response. A second circuit coupled in series with the first circuit and operating according to a second frequency response an inverse of the first frequency response can receive the amplified first voltage and generate, based at least on the amplified first voltage adjusted by the second frequency response, a second voltage indicative of the mode hop event within a second response time that is shorter than the first response time.

Abstract: A golf rangefinder system comprises a GPS golf rangefinder device and an accessory. The golf rangefinder device comprises a housing defining a forward housing portion with a display screen viewable therein, and a rearward housing portion with a convexity projecting therefrom. A magnet centrally positioned at a distal most portion of the convexity. The accessory includes a clip with a hook-shaped member and a receptacle portion for mating with the convexity of the housing of the golf rangefinder device. A second magnet is positioned in a recess in the receptacle portion. The receptacle portion configured as a concavity and conforming to the convexity of the rangefinder device whereby when the accessory and rangefinder device are in proximity with each other they are magnetically coupled with the convexity positioned in the concavity. The accessory and rangefinder slidably rotatable and movable with respect to one another while still maintaining the magnetic coupling.

Abstract: A system for conducting a video conference and methods for making and utilizing the same. The system can generate a first virtual stage for a first participant in the video conference by selecting one or more items of personal information associated with the first conference participant and disposing the selected personal information items in a predetermined arrangement. The first virtual stage can be transmitted with a first visual image of the first conference participant to a computer system associated with a second conference participant for visual presentation during the video conference. The system advantageously can enable the computer system associated with each conference participate to visually present a visual image with an associated virtual stage for each of the other conference participants.

Abstract: The invention relates to sized reinforcing fibers that comprise a reinforcing fiber sized with a fluoropolymer. The fluoropolymer is functionalized and/or the reinforcing fiber is sized with a compatible functional non-fluorinated polymer that is compatible with the fluoropolymer. Functionalization of the fluoropolymer or the compatible non-fluorinated polymer provides enhanced properties, such as increased adhesion to the reinforcing fiber.

Abstract: An adapter holder assembly supports one or more optical adapters. The adapter holder includes first and second holding members spaced from each other. Inner sides of the holding members define one or more mounting channels each having a corresponding latching arm. The optical adapters mount to the holder assembly by sliding over the latching arms towards stop surfaces defined by the holding members. In certain implementations, the optical adapter is releasable by applying sufficient force to the optical adapter along a slide axis away from the respective stop surface.
