Abstract: The invention is related to contact lenses that not only comprise the much desired water gradient structural configurations, but also have a minimized uptakes of polycationic antimicrobials and a long-lasting surface hydrophilicity and wettability even after going through a 30-days lens care regime. Because of the water gradient structural configuration and a relatively-thick, extremely-soft and water-rich hydrogel surface layer, a contact lens of the invention can provide superior wearing comfort. Further, a contact lens of the invention is compatible with multipurpose lens care solutions present in the market and can endure the harsh lens care handling conditions (e.g., digital rubbings, accidental inversion of contact lenses, etc.) encountered in a daily lens care regime. As such, they are suitable to be used as weekly- or monthly-disposable water gradient contact lenses.

Abstract: A system prevents activation of strobe lights on a vehicle in response to events calculated to indicate a nuisance activation. Directional strobing may be activated based on input from vehicles systems.

Abstract: A hazard beacon has an interface to a vehicle wiring harness configured to detect that vehicle emergency indicators have been deployed, a plurality of separately strobe capable light segments forming a hazard symbol, and a microcontroller controlling operation of the plurality of separately strobe capable light segments.

Abstract: A blister fabric formed of a double layer jersey knit which is needled to produce internal connections of filaments and/or fibers from yarns extending into, and/or between, the yarns of an adjacent layer.

Abstract: An amphibious walking vehicle having a mobile and stable structure which moves at a constant speed whether the vehicle is on land or on water. In the water the vehicle floats and is driven by a conventional propeller system. However, when on land the vehicle moves on pontoons which are successively moved ahead while the decks and superstructures which carry the payload are shifted from the stationary pontoon. The decks rest on an inboard or center pontoon and a pair of independent outboard pontoons which are connected to operate together. The amphibious walking transporter has a gear drive system which sequentially moves the center or inboard pontoon ahead while the outboard pontoons are stationary while carrying the payload, and vice versa. Each pontoon is successively moved by a gear system, including a sequential half-gear system and gear racks in combination with an ovate chain drive connected to a motor or engine through a chain drive floating shaft and rocker arms.
