  • Patent number: 7053499
    Abstract: An antitheft device for a motor vehicle has a first receiver (2) in the motor vehicle, which is designed to receive signals in narrowband. The signals received by this receiver are evaluated in accordance with the code information contained in them. Furthermore, the antitheft device has a second broadband receiver (7) which receives signals outside the useful frequency band (3). If signals are received whose signal strength is above a threshold value (S), whose signal duration is shorter than a predefined time period (t2–t1) or whose code information corresponds largely to anticipated code information, the access to the motor vehicle, and its use, are not enabled.

  • Patent number: 7013295
    Abstract: Purchase of information items from a merchant over the Internet or other network is implemented so as to ensure that the merchant is unable to identify the particular information item(s) purchased by a user. The user when considering purchase of a given information item is permitted to access a corresponding signed ciphertext of that item. The signed ciphertext in an illustrative embodiment includes a first ciphertext portion in the form of a symmetric key encrypted using a public key associated with the merchant, a second ciphertext portion corresponding to the information item encrypted using the symmetric key, an unencrypted description of the information item, and a tag corresponding to a signature. The user requests purchase of the information item by sending a blinded version of the first ciphertext portion to a payment server along with an appropriate payment. The payment server decrypts the blinded version of the first ciphertext portion and returns the resulting symmetric key to the user.

  • Patent number: 6991694
    Abstract: A method of making a tailgate for a pickup truck or the like includes selecting a pair of polymer sheets and selecting a flexible fiberglass woven mat and sandwiching the selected fiberglass woven mat between the selected pair of polymer sheets. The sandwiched mat polymer sheets are placed on a tailgate forming mold for molding the inner tailgate panel from the sandwiched matted polymer sheets. The inner tailgate panel has a plurality of spacing reinforcing ribs thereon. The outer tailgate panel is formed and the ribs on the inner tailgate panel have a cold setting adhesive applied thereto for binding the outer tailgate panel thereover to form a tailgate having inner and outer fiberglass reinforced polymer panels spaced and reinforced by a plurality of intersecting ribs. Once the inner and outer panels have been positioned, they are placed in a fixture to hold them while the adhesive cures.

  • Patent number: 6986816
    Abstract: The invention relates to a process for the removal of deposits formed in a reaction apparatus by the precipitation of solids from a liquid reaction mixture, which process is characterized in that particles of a material that is inert under the reaction conditions are introduced into the reaction apparatus, which particles, by suitable mechanical circulation of the reaction mixture, are so moved through the reactor that, during the reaction, by striking the walls or other built-in elements, they abrasively remove precipitates adhered thereto.

  • Publication number: 20050220884
    Abstract: This free-flowing, powdery composition containing ?-lipoic acid (derivatives) is distinguished by comprising, besides the lipoic acid component, from 0.1 to 25% by weight, based on the total weight of the composition, of a hydrophilic or hydrophobic silica-based flow aid which has a particle size (×100 value) of <800 ?m and a tamped density of from 50 to 600 g/l. The lipoic acid component is moreover not confined to the free acid form, but may also be at least partly in the form of its salts. Preferred flow aids are spray-dried precipitated silicas and/or highly dispersed silicas and/or amorphous silica gels. Besides the particle size and the tamped density, the flow aid employed may also be characterized by its specific surface area, which preferably ought to be between 30 and 1000 m2/g, or by the fact that the flow aid brings about a pH of between 3 and 11.5 in a concentration of 5% in aqueous solution.

  • Patent number: 6931126
    Abstract: A fast encryption method particularly useful for long message lengths is provided. A message m is encrypted using a transmitter secret key z to form a quantity E. A transmitter processor prepares a quadruplet (anew, bnew,snew, E) where: anew=z*ycmodulo p; bnew=gcmodulo p; snew=signaturec(anew,bnew,E). As in previous embodiments y=gxmodulo p is the public key and x is the receiver secret key. The parameters g, x, and p according to methods known to a person skilled in the art and the parameter g is a generator of the group Gp. The parameter c is a random number. The transmitter processor sends the quadruplet (anew, bnew,snew, E) to a receiver processor. The receiver processor verifies the signature on snew using methods known in the art. The receiver processor then decrypts anew and bnew using the receiver secret key x to get the transmitter secret key z, i.e. in the following manner z=anew/bnewx. The receiver processor uses the transmitter secret key z to decrypt E to get the message M.
