Abstract: Computer implemented systems and methods are disclosed for automatically and canonically identifying related data in various data structures while maintaining secure access to individual data objects and their properties. Data structures may include a plurality of records, wherein each record is associated with a respective entity. Access to individual records, or in some embodiments access to individual attributes of a record, may be restricted to particular users or groups on a per-item basis. In accordance with some embodiments, systems and methods are disclosed for identifying pairs of records, determining a probability that both records relate to a common entity, and securely notifying and presenting users with information regarding the probability while preserving the access restrictions for the individual records and attributes. Record pairs that potentially refer to the same entity may be linked, reconciled, or ignored in response to feedback from users who have access to one or both records.

Abstract: In an IR jamming system for defense against missiles with IR-sensitive homing heads, one or more jamming beams are generated, whose diameter is less than that of the optical aperture of the IR-sensitive homing head of the missile. The optical aperture of the IR-sensitive homing head of the missile is at least partially illuminated by the jamming beam or beams.

Abstract: In a method and apparatus for defense against missiles that have explosive substances and piezoelectric detonators, the detonator of the missile is excited by ultrasonic radiation, causing it to oscillate and thus be triggered in flight.

Abstract: A hypodermic syringe (1, 2) includes a needle (3) covered by a needle sheath (4) that comprises a tubular sheath body (5) with a removable end cap (6). Injectant is transferred into the main body (1) of the syringe by removing the end cap, inserting the needle together with the sheath body (5) into a source of injectant and operating the plunger so as to draw the injectant through open end (6) of the plunger through the needle into the main body. The process is carried out without exposing the needle to the user's touch.

Abstract: A syringe has a capsule assembly (1) which is pre-loaded with injectant fluid (1.10) and is provided with a needle (1.2) that is covered by a sealed needle sheath (1.4). The capsule assembly (1) is placed into a housing (2). The sealed capsule is prepared for use by removal of the sealed needle sheath (1.4). A plunger (4) with an associated piston (5) is used to input the fluid (1.10). The capsule assembly (1) including the needle (1.2) is automatically retracted into the housing (2) after use.
