  • Patent number: 5422632
    Abstract: Electronic security system for controlling access to an automotive vehicle. The security system includes a computer system having a processor subsystem connected to selectively enable or disable an ignition system of the automobile and a memory subsystem having ignition, valet and reprogramming key codes and first, second and third validation codes stored therein. To control access to the vehicle, an encoded signal containing a device code and an authorization code is propagated to the processor subsystem where the codes are compared to the ignition key, valet key, reprogramming key and validation codes. If the propagated device and authorization codes match the ignition key and first validation codes, the processor subsystem enables the ignition system for a pre-selected time period. If the propagated device and authorization codes match the valet key and second validation codes, the processor subsystem enables the ignition system.

  • Patent number: 5420136
    Abstract: A class of predominantly hydrophobic non-azo N-substituted 1,8-naphthalimide compounds, each bearing, at its 3-position, a nucleofuge and, at its 4-position, a heteroatomic electron-releasing group. The heteroatomic electron-releasing group is being characterized as having a heteroatom directly linked to the 4-position of the ring, and having at least one hydrogen directly attached to the heteroatom. Upon activation by an activating agent in an environment independent of the presence or absence of oxygen, these compounds generate activated species. The activated species initiate chemical changes in lipid bilayer membranes of viruses and other target cells. These changes can eradicate viruses and other target cells. The activated species can also cause structural changes in lipid and any associated proteins and polypeptides at a level beneath the surface of the membrane, leading to polymerization and crosslinking.

  • Patent number: 5417141
    Abstract: An aircraft armament mounting system includes an elongated support plank member which is insertable transversely through the aircraft cabin area so that a central portion of the plank is disposed within the cabin area and its opposite end portions project outwardly from the aircraft. The central plank portion is anchored to the air craft, and removable outer tip portions of the plank are vertically pivotable, about horizontal hinge lines, between extended and inwardly folded positions. When the outer plank tip portions are removed, specially designed mounting structures may be used to mount armament devices, such as machine guns, at the hinge lines at the outer ends of the remaining longitudinal plank portion. Representatively, these armament devices are .50 caliber machine guns housed in open framed pod structures having enclosed front end portions through which the jacketed barrels of the guns extend.

  • Patent number: 5414916
    Abstract: A high density ink jet printhead is fabricated by first forming a body subassembly comprising a piezoelectric main block having metallic layers disposed on opposite first and second sides thereof, and piezoelectric sheets secured to front portions of the metallic layers. Using a precision dicing saw, a first spaced series of parallel grooves, longitudinally extending between the front and rear ends of the subassembly, are cut into the first side of the subassembly. The subassembly is then placed, groove side down, in a support fixture having mirrors secured thereto and positioned adjacent the opposite ends of the grooves. Reflections of opposite groove ends in the mirrors are then used as line-of-sight guides to position the saw which is then used to form a second series of grooves in the second subassembly side which are in precise lateral alignment with the first series of grooves.

  • Patent number: 5415163
    Abstract: Method for diagnosing and treating tissue suspected of containing a lesion. A shaped pulse sequence is selected for each of waveform, phase and frequency components of an RF signal based upon characteristics of the tissue suspected of containing a lesion and an RF signal comprised of the selected waveform, amplitude and frequency shaped pulse sequences generated. A series of echoes is received in response to the generated RF signal and a real-time MR image of the tissue suspected of containing a lesion is produced using the series of received echoes. The tissue is then diagnostically evaluated for the presence of lesions using the produced real-time MR image.

  • Patent number: 5409703
    Abstract: A therapeutic medical device is described that is comprised of a dried hydrogel of a hydrophilic-hygroscopic polymer, such as an unmodified or modified polymeric carbohydrate, in the form of a solid foam. The dried hydrogel is prepared by preferably freeze-drying a hydrogel of this polymer in a liquid medium, such as water. The dried hydrogel can be sterilized by radiation or other means so that the sterilized product has a relatively indefinite shelf-life without refrigeration. The resultant dried hydrogel can be transformed into a hydrogel upon absorption of addition liquid medium. The described therapeutic device can serve as a dressing for a wound or lesion, drug delivery system, a hemostatic agent and a biologic response modifier. The described therapeutic device enhances the wound healing rate.

  • Patent number: 5407324
    Abstract: An axial flow cooling fan includes a rectangular housing base portion and a plurality of rectangular plate members, all having corner portions and central circular air flow openings. The plate members have corner openings and integral hollow cylindrical spacer members formed on side surfaces of their corner portions and aligned with their corner openings. To construct the housing subassembly the base portion post members are sequentially inserted through the corner openings of each plate member. Resilient finger structures on the outer ends of the post members create a snap-fitted locking engagement with the outermost plate member and anchor the plate members in a stacked, parallel relationship in which the installed plate members are held apart by their integral spacer portions to create side air inlet openings on the subassembly at edge portions of the stacked plate members. The housing base portion has a motor-driven impeller section operatively supported within its central air flow opening.

  • Patent number: 5403417
    Abstract: A punctured, substantially deflated pneumatic automotive tire is internally sealed using a specially designed sealant canister containing CO.sub.2 gas propellant and a tire sealant mixture. The canister sealant comprises approximately 97% by weight of an acrylic latex material which is present with the propellant under a pre-use internal pressure of about 55-65 psig. An outlet cone portion of the canister is removably connectable to the tire inflation valve, and the internal volume and pre-use pressure of the canister are related to the internal volume and normal full inflation pressure of the tire in a manner such that the canister is operative to deliver essentially its entire contents into the tire, yet only partially inflates the substantially deflated tire past its initial pressure.
