Title: Dead bolt combination lock and push-pull lock, each with integrated re-locking features, lock with auxiliary security features, and lock keypad with tamper detection and response features
Inventor: CLARK MICHAEL R
IPC: E05B63/06
Filed: 1998-12-30
Granted: 2001-02-21
Abstract: A dead bolt lock automatically blocks the extended bolt to prevent externally-applied force from thrusting the bolt back into the lock case, and in the event of physical attack the lock responds by prolonging or perpetuating the dead bolt blocking condition. A push-pull lock has a bolt whose motion in both directions is stopped in response to detection of a rise in motor current above a certain level: a cushioning arrangement allows the current-limiting feature to be implemented without risk of damage to the motor, gear teeth or other drive components. A re-locker arrangement includes an angled flange that is part of a motor-supporting bracket; when forcibly pressed, the flange breaks plastic pins to release a spring-biased re-locker wire to block the bolt from being withdrawn, and when the wire is in the dead bolting position an extension of the re-locker wire engages a ridge in the lock's case to prevent the re-locker from being manipulated back to its original position. Either lock can control the position of a bolt works blocking element that selectively engages a lever-driven mechanism that blocks and unblocks the door from being opened. A sensor switch, especially for use on the push-pull lock, tells the lock when the mechanism is in a secured position, so that the lock is automatically re-locked and the user does not have to manually extend the bolt. Finally, the system has a keypad tampering detection and response system, remote enable/disable unit, duress detection and response unit, low-battery sensing arrangement, bolt extension indication feature, adjustable bolt throw feature, and audit trail feature.

Title: See-saw switch
Inventor: ITO RYOJI
IPC: H01H5/04
Filed: 1999-02-20
Granted: 2001-02-11
Abstract: A see-saw switch is able to close a contact under a high initial pressure. The see-saw switch includes a housing having a stationary contact, and a lever having a vertical end provided with a movable contact. The lever is mounted on the housing to be moved by leverage between a close position and an open position based on a central pivot. A plunger is supported by the housing in a sliding manner to linearly moved in the axial direction of the plunger. A driver is provided to contact with the lever in a sliding manner, so as to transform the linear movement of the plunger into the levering movement of the lever. When the plunger is moved in a forward direction, the driver enables the lever to perform a levering movement around the central pivot so as to reach the close position. A limiter is used to keep the lever and the plunger in contact, so as to restrict the lever to move from the opening position to the close position until the driver passes through a threshold point in a forward direction, wherein the threshold point is diverted from the central pivot with a specific distance along the lever toward the movable contact. Therefore, only after the driver pass through the threshold, the contact is close by the levering movement and the driver can provide a substantial contacting initial voltage between the contacts.

Title: On-line handwritten Chinese character recognition apparatus
Inventor: JANG YI-WEN
IPC: G06K9/22
Filed: 1999-08-24
Granted: 2001-07-21
Abstract: An on-line handwritten Chinese character recognition apparatus based on character shapes uses a reference file for look-up of compressed codes-sequence codes in a conventional input method founded on dismantling by character shapes as reference when comparing character to reduce the number of matching templates required in the on-line handwritten Chinese character recognition system and to lower the time for matching. Input handwritten Chinese characters are dismantled into constituting radicals. Thereafter, with reference to code retrieving rules of the input method, and based on the character composing method of handwritten characters, radicals for comparison are retrieved. Then, the compression formula of the input method is used to compress the codes of the base radicals, and the compressed codes are compared with contents of the input method reference file to obtain the sequence codes of candidate characters. Finally, the final recognized sequence code is decided via further comparison during post-processing. The character that corresponds to the sequence code in a character font file is the recognition result and is outputted.
