Abstract: A hood latch assembly (10) has a housing (14) having a mouth (13). A ratchet (16) is pivotally mounted within the housing (14) to cooperate with the mouth (13) to pivot between an open, a secondary closed and a primary closed condition for receiving, engaging and cinching a keeper of a striker (80). The ratchet (16) is biased to the open condition. A pivotally mounted primary pawl (18) is biased for engagement with the ratchet (16) to releasably retain the ratchet (16) in the primary closed condition. A pivotally mounted secondary pawl (62) is biased for engagement with the ratchet (16) to releasably retain the ratchet (16) in the secondary closed condition. The secondary pawl (62) has a release lever (20) which rotates between a deployed position and a retracted position. As the ratchet (16) engages the striker (80), the ratchet (16) will rotate in a latching sense from the open condition to the secondary closed condition.

Abstract: Synthetic biomaterials are provided with irreversibly bound amino diphosphonate, polyphosphonate, or other anticalcification agent to prevent in vivo calcification. Such biomaterials include biocompatible elastomers such as polyurethane and/or polydimethylsiloxane, and the like which are intended for invasive, or in-dwelling use in a human or animal body. Illustratively, reaction conditions utilizing hi-or polyfunctional epoxides result in epoxide bridge incorporation of the anticalcification agent to the biomaterial elastomer.
