  • Patent number: 8776558
    Abstract: A system for detecting defects in a pipe wall, comprises an ultrasonic transducer which is arranged for emitting, via an exit opening, ultrasonic signals from the interior of the pipe towards its wall and for receiving, via an entrance opening, backscattered signals from the wall. The system is arranged to emit and receive a multitude of signals having their main directions within a plane mainly perpendicular to the pipe axis. The openings are configured to make the ultrasonic transmission signal diverge and/or to receive back signals from a diverging range of angles over a large area of the pipe wall, by using openings with a diameter with magnitude of the wavelength of the ultrasonic signals. Sets of emitted and backscattered signals for different emission and reception positions are processed, in processing means, to form an image based on transmission times between emission and reception of backscattered signals.

  • Patent number: 6530248
    Abstract: This invention relates to a lock assembly to be used in conjunction with two or more padlock assemblies. The lock assembly comprises a main body 1, a main shackle 2, and a locking portion 7. When all subsidiary padlocks 5, 6 are locked into the apertures 3, 4 the main shackle 2 cannot be opened. The removal of either subsidiary shackle allows the locking portion 7 to circumvent the second subsidiary shackle and the main shackle 2 may be opened. This allows two persons to independently use the padlock without sharing keys or other secure information. Moreover the lock assembly may be used with any secure fitting designed for use with a traditional padlock.

  • Patent number: 6430975
    Abstract: Changing the locking mechanism in a U-lock, cable lock or other tie lock as often as desired is achieved without compromising the lock's resistance to physical damage. This function is achieved by an auxiliary sleeve that removably fits over the U-lock's crossbar or the cable lock's end bar. Either bar provides an aperture, which is too small to permit the locking mechanism to be picked or pried, but which is operatively positioned and sufficiently large to provide access for a key to the keyway of the locking mechanism.

  • Patent number: 6397648
    Abstract: A keyway protector having housing and the slider. The housing hugs the crossbar of a U-lock and secured by screws. The slider fits into a shallow depression in the inner surface of the housing and moves between open and closed positions. In the open position, an aperture in the housing, a hole in the slider, and the keyway are aligned to allow access to the keyway. In the closed position, the slider hole is not aligned, denying access to the keyway. A knob outside the housing is used to move the slider. Protrusions in opposed pivoting arms on the slider snap into opposed notches in the depression walls to hold the slider in the open or closed position.

  • Patent number: 6393411
    Abstract: A secure funds device for use with a computer system, such as a personal computer, for transferring funds, in response to a funds transfer request for amounts of funds from the computer system, to a funds receiver. One or more electronic cash devices store electronic funds and transfer funds in response to funds transfer request when authorized by an authorization signal. A processor is used for connecting the funds transfer request from the computer system to the electronic cash device and for transferring electronic funds from the electronic cash device to the computer system when the authorization signal is present. User control means, including for example a pushbutton switch and an LCD display, that is not accessible by the computer system is used for providing the authorization signal. The secure funds device has a secure interface that prevents the computer system from generating the authorization signal.

  • Patent number: 6373382
    Abstract: Embodiments of an alarm system are described, which may be mounted or built-in to a bicycle or other device which is in need of anti-theft protection. A loud alarm is connected to or mounted in the protected device, and is operatively connected to either or both: a lock that anchors the device to a stationary object, and/or parts of the protected device that might be stolen or vandalized. The alarm unit is built and wired in such a way that the lock or parts of the protected device may not be significantly tampered with or removed without triggering the alarm. Externally-mounted alarm units preferably include a weather-proof casing, which contains a unique clamping feature that makes the alarm tamper-resistant or tamper-proof. The alarm casing may contain a sound chamber that preferably amplifies the alarm sound, waterproofs the alarm component, and prevents a thief from muffling the sound.

  • Patent number: 6101852
    Abstract: An improved padlock assembly is provided which includes a lock body, a shackle with a pair of opposed legs fitting into the lock body, and the lock body including an interior chamber in which are positioned a pair of reciprocal lock plates. A first lock plate operates in response to the manipulation of the lock cylinder, while the second lock plate operates in response to a lock pin to keep it in a locked and/or unlocked position. The entire shackle may be removed by first removing the first shackle leg from locking engagement with the first lock plate, moving the first lock plate back to its locked position, afterwhich the lock pin may then be removed to move the second lock plate to its unlocked position in order to free the second leg of the shackle and thereby remove the entire shackle.

  • Patent number: 6055833
    Abstract: A plug lock assembly is provided. The assembly comprises a sleeve member to which a detent catch member, a cylinder member, and a latch member are coupled. The detent catch member engages a face wall portion of the sleeve member through cooperating cambered surfaces such that the detent catch member may be placed into and out of its locking position. The detent catch member has formed thereon an open cambered groove section which is engaged by a locating pin extending from the sleeve member for limiting the axial displacement of the detent catch member in at least one direction. This reinforces the lock assembly against compromise of its locking function.

  • Patent number: 5950461
    Abstract: A lock mechanism structure includes a pair of latches with one end of each latch positioned against a spring and the other end of which are engaged with a rod. A block has a spring urging the block outwardly which in turn urges the latches outwardly to extend into a recess, whereas the other end of the block has a slope surface engaging with a corresponding slanting surface on a bulge extending upward from a rotating plate of a lock core, thus, when opening the lock, the lock core rotates to bring the bulge to push the block upwardly, whereas the other end of the block descends to urge the spring to retract, this allows the latch to detach from the recess and the lock is in a released status.
