Patent number: 8156778Abstract: The framer, also referred to as the scrambler/Reed-Solomon encoder (SRS), is a part of the transmitter and accepts user and control data in the form of one or more logical channels, partitions this data into frames, adds error correction codes, randomizes the data through a scrambler, and multiplexes logical channels into a single data stream. The multiplexed data is then passed to the constellation encoder as the next step in the formation of the VDSL symbol. The deframer, also referred as the descrambler/Reed-Solomon decoder (DRS), is part of the receiver and performs the inverse function of the framer.Type: GrantFiled: May 28, 2010Date of Patent: April 17, 2012Assignee: Metanoia Technologies, Inc.Inventors: Ravi G. Mantri, Christopher R. Hansen, Terry C. Brown

Patent number: 7178372Abstract: A combination of a locking button and a spindle for a lock includes a spindle having a longitudinal hole and a locking button having a grip portion for manual turning and a shank that is mounted in the longitudinal hole of the spindle. A guiding groove is defined in a circumference delimiting the longitudinal hole and extending along a circumferential direction. The shank includes a coupling section including a protrusion engaged in the guiding groove and movable between two end walls delimiting the guiding groove, allowing the locking button to be movable between a locking position and an unlocking position.Type: GrantFiled: January 13, 2006Date of Patent: February 20, 2007Assignee: I-Tek Metal Mfg. Co., Ltd.Inventor: Mu-Lin Shen

Patent number: 6553799Abstract: A push button door locking mechanism including a push button mounted on a push button carrier housed within an inside spindle of a door lock assembly, a main retractor co-rotatingly attached to the spindle, and an inner cam aligned axially with the push button carrier. The inner cam has a flange portion extending substantially perpendicularly from a driver bar portion of the inner cam. The locking mechanism also includes a locking catch assembly having a first end and a second end. The first end includes a head portion formed to matingly engage the push button carrier. The second end is coupled to a locking wing. The locking catch assembly has a locked position wherein the locking wing matingly engages the flange preventing rotation of the flange with respect to the main retractor and an unlocked position allowing rotation of the flange with respect to the main retractor.Type: GrantFiled: February 23, 2001Date of Patent: April 29, 2003Assignee: Schlage Lock CompanyInventors: Peter K. Bates, Truman Bradley, Thor Hendrickson, Dario L. Pompeii

Patent number: 5987947Abstract: A manual control device includes an actuated tube which is connected to the stem member contacting against the rod movably received in the plug of the pickproof lock, an operating member securely connected to the actuating tube by receiving the boss thereof in the groove defined in the actuating tube, wherein the operating member has a rib so as to be frictionally received in the actuating tube. Both of the actuating tube and the operating member are received in the sleeve which has an L-shaped groove into which the protrusion extending from the actuating tube is movably received. The stem member pushes the rod of the pickproof lock by pushing the combination of the actuating tube and the operation member and rotating the combination to let the protrusion be securely positioned in the L-shaped groove of the sleeve.Type: GrantFiled: January 19, 1999Date of Patent: November 23, 1999Inventor: Mu-Lin Shen

Patent number: 5865050Abstract: A locking cover for a dead bolt lock assembly that permits a user to put it in one of three positions: neutral, locked and unlocked. The cover in the neutral position permits the operation of the bolt lock assembly normally. The other positions limit the rotational travel of the actuating shaft to one quarter of a turn. The actuating shaft is rotated by turning the locking cover that includes a central tubular cylinder for selective engagement with the actuating shaft. A pin mounted on the interior of the cover is receivable within one of three holes on an annular base plate that limits the rotation of the actuating shaft.Type: GrantFiled: October 15, 1996Date of Patent: February 2, 1999Inventors: Yves Michaud, Alain Belanger

Patent number: 5598726Abstract: A lockset suitable for use on doors of different thicknesses comprises inside and outside knobs mounted on inside and outside spindles which are in turn rotatably supported in inside and outside chassis. Rotation of either knob causes rotation of a rectangular driver spindle to drive a latch operating assembly which retracts a latchbolt. Locking may be accomplished only by pressing a push button located in the inside knob. In one embodiment the push button drives a caliper spring to engage and axially move a plunger bar and in a second embodiment a hook spring carried on the push button engages teeth on the plunger bar. Axial movement of the plunger bar actuates a clutch mechanism to disconnect the outside knob from the driver spindle and lock the outside knob to the outside chassis to prevent rotation of the knob. In the first embodiment unlocking is accomplished by rotating the plunger bar relative to a coupler having a spring thereon for engaging notches on the plunger bar.Type: GrantFiled: March 29, 1996Date of Patent: February 4, 1997Assignee: Schlage Lock CompanyInventor: William H. Cordle

Patent number: 4941697Abstract: An over-loading idling lock set having an actuating shaft connected to an indoor lock core and an outdoor sealing block wherein the sealing block is connected to an outdoor lock core, and plural ball members pushed by corresponding restricting springs are disposed between the sealing block and outdoor lock core whereby the ball members are partially extended into corresponding restricting holes formed on the sealing block to associate the outdoor lock core with the sealing block. By means of turning an indoor or outdoor handle, the actuating shaft is rotated to open the lock set. When closing the lock set, a controlling bolt is inserted into a longitudinal groove formed on the indoor lock core to lock the same and thus when turning the outdoor handle, the ball members are separate from the restricting holes due to insufficient spring force. Therefore, the outdoor handle can only idle without opening the lock set.Type: GrantFiled: November 28, 1989Date of Patent: July 17, 1990Inventor: Caesar Fan

Patent number: 4594864Abstract: A lockset assembly which includes a bolt (12) movable between a partially extended latching position and a fully extended dead bolt position. When the bolt (12) is in the dead bolt position, the inside lever (10) can be used to retract the bolt. The outside operating assembly (27) is provided with a key operated lock cylinder (22) and the inside operating assembly (44) is provided with a turn button (26).Type: GrantFiled: September 30, 1983Date of Patent: June 17, 1986Assignee: Emhart Industries, Inc.Inventor: Leroy Hart
