  • Publication number: 20050118889
    Abstract: Provided is an electrical connector having first and second surfaces and configured to establish electrical communication between two or more electrical devices. The electrical connector includes an insulative housing and a resilient, conductive contact retained in an aperture disposed from the first surface to the second surface. To contact the electrical devices, the contact includes a center portion from which extends two diverging, cantilevered spring arms that project beyond either surface of the electrical connector. To shorten the path that current must travel through the contact, one spring arm terminates in a bellows leg that extends proximate to the second spring arm. When placed between the electrical devices, the spring arms are deflected together causing the bellows leg to press against the second spring arm. For retaining the contact within the aperture, the contact also includes retention members extending from the center portion that engage the insulative housing.

  • Publication number: 20040168087
    Abstract: A computer system includes: a data-handling system operable to receive and transmit data over a data path; a storage device operatively coupled to the data-handling system to receive data from and deliver stored data to the data-handling system; and a security element operatively coupled between an external data path and the data-handling system via the data path, the security element establishing the data path as a trusted path, wherein the data-handling system, the storage device and the security element are disposed in a common physical housing such that access to the data path requires breach of the housing.

  • Publication number: 20030074578
    Abstract: This invention provides a system for the prevention of the spread of a computer virus by intercepting outgoing messages from a computer device and determining whether the message is of an acceptable type. The system is provided as a firedoor that compares outgoing messages to a previously established list of approved actions and, if the message does not conform to an approved action on the list, the firedoor blocks transmission and prevents the virus from spreading any further. If a further embodiment, multiple firedoors are applied in a cascaded series to compare the transmission to different acceptance criteria in tandem.

  • Patent number: 4595784
    Abstract: A compound having the general formula R.sub.x COH[COR].sub.y, wherein R is a lower alkyl hydrocarbon radical, y is 0 or 1, and x is 2 when y is 1 and 3 when y is 0, is prepared by admixing carbon monoxide, a transition metal halide, and an organomonolithium compound or an anionic equivalent thereof.

  • Patent number: 4460513
    Abstract: Tertiary organic hyponitrite usable as initiators for polymerizing ethylenically unsaturated compounds are prepared by reacting an alkali metal, alkaline earth, ammonium or substituted ammonium salt of hyponitrite, such as sodium hyponitrite, with a tertiary organic halide, such as tert-butyl chloride, in the presence of one or more weak Friedel-Crafts catalysts, such as ferric or zinc chloride, and in a solution of a neutral solvent.
