20110288644INTERVERTEBRAL PROSTHETIC SYSTEMS, DEVICES, AND ASSOCIATED METHODS - Intervertebral prosthetic systems, devices, and associated methods are provided. The present disclosure provides intervertebral prosthetic devices that include lateral plates to engage the lateral walls of the vertebral bodies for stability and include a compliant central component, fusion-cage central component, or any other suitable type of motion-preserving or fusion component positioned between the lateral plates. In some instances, the lateral plates and the central component are connected by an elongated member that extends across the disc space. The designs of the present disclosure allow insertion through a unilateral approach yet still have engagement on both sides of the vertebral body to provide stability and reduce the risk of subsidence.11-24-2011
20110288645INTERVERTEBRAL PROSTHETIC SYSTEMS, DEVICES, AND ASSOCIATED METHODS - Intervertebral prosthetic systems, devices, and associated methods are provided. The present disclosure provides top and bottom endplates that engage the lateral walls of the vertebral bodies for stability and incorporate a compliant core, ball-and-socket core, fusion-cage core, or any other suitable type of motion-preserving or fusion cores. The endplate designs allow insertion through a unilateral approach yet still have engagement on both sides of the vertebral body to provide stability and reduce the risk of subsidence. In some instances, saddle style endplates are inserted and then rotated to engage the lateral walls of the vertebral bodies. In other instances, hinged style endplates are inserted in a first orientation and then at least one end portion is pivoted to a second orientation so that the endplates engage the lateral walls of the vertebral bodies.11-24-2011

20080258911EXIT ALARM ESCUTCHEON - An exit alarm system housed in an escutcheon for activating upon movement of an interior latch operator. The system is mounted to the interior side of a door with a latch assembly including an interior latch operator. The system may include an alarm, a trigger, and an electronic module. The trigger is responsive to movement of the interior latch operator. The electronic module may be electrically connected to a power source for providing an input signal to the alarm. Upon motion of the interior latch operator, the trigger may cause the electronic module to send an activating input signal to the alarm. The alarm may be a sound transducer. A switch may be provide to arm the system. A tamper switch may be provided to cause the electronic module to activate the alarm upon removal of the escutcheon. The system may be applied to retrofit an existing door.10-23-2008
20090152875Adjustable Backset lockset - A lock assembly comprises a housing and a latchbolt including an attachment member. A retractor element is disposed within the housing for linear reciprocating movement. The retractor element includes a first attachment location at a first position relative to the axis of reciprocation of the retractor element and a second attachment location at a second position relative to the axis of reciprocation of the retractor element. The second attachment location is spaced from the first attachment location by a distance along the axis of reciprocation of the retractor element. The attachment member of the latchbolt is selectively engageable with the retractor element at either the first attachment location or the second attachment location for movement together with the retractor element. An operator is operatively connected to the retractor element for facilitating selective reciprocation of the retractor element for moving the latchbolt between a latched position and an unlatched position.06-18-2009
20100192647HOUSING FOR ELECTRONIC LOCK - A housing assembly adapted to fit into a mortised recess in a door is provided for accommodating components of an electronic lock mechanism. The housing assembly comprises a housing including opposed major side walls at least partially defining an opening into the housing. A circuit board comprising electronic circuitry for operating the lock mechanism is disposed in the housing. A bracket for holding batteries is adapted to be disposed in the opening in the housing. The bracket is accessible when the housing is in the mortised recess of the door such that the bracket is movable relative to the housing between a first position and a second position. In the first position the bracket is in the housing and in the second position the bracket is at least partially outside of the housing such that batteries may be inserted into or removed from the bracket.08-05-2010
20100307207ADJUSTABLE BACKSET LOCKSET - A lock assembly including a latchbolt that may be effectively lengthened to accommodate varied backset distances for doors. The lock assembly may include a housing, a latchbolt including an attachment member, an extension member, a retractor element, and an operator. The extension member may be mounted to the attachment member to extend from the latchbolt for effective lengthening of the latchbolt. The retractor element, operatively responsive to the operator, is disposed within the housing for linear reciprocating movement to move the latchbolt, and is selectively engageable with the attachment member or with the extension member. The extension member defines a recess adapted to receive the attachment member. A latch case may receive the latchbolt, and a cylindrical sleeve may receive the latch case and the latchbolt when the extension member is in use to increase the backset dimension.12-09-2010

20110287532EXPRESSION OF FACTOR IX IN GENE THERAPY VECTORS - Two mechanisms are provided for improving the expression of Factor IX in gene therapy vectors. The first is the use of a specific Factor IX polynucleotide coding sequence designed for optimal expression. The second is the use of transcriptional regulatory regions minimized in size so that they can be used to express Factor IX, as well as any other gene of interest, in a size-constrained environment such as in a self complementary gene therapy vector system.11-24-2011

20080246288Reversible Latch Bolt - A latch assembly comprises a first portion (10-09-2008
20090079204DELAYED EGRESS EXIT DEVICE - A touch bar (03-26-2009
20090189399REVERSIBLE LATCH BOLT - A latch is provided for a mortise lock of the type comprising a housing for accommodating the lock components. The latch comprises a first and second portions movably mounted in the housing and a securing element for releasably connecting the first and second portions in either a first relative axial position or a second relative axial position where the first and second portions of the latch are rotatable relative to one another. In the first axially connected position of the latch, the first and second portions of the latch are movable together relative to the housing so that the first portion at least partially non-rotatably projects outwardly from the opening in the housing in an extended position of the latch, and the first portion is inside the housing in a retracted position of the latch. In the second axially connected position of the latch, the first portion of the latch extends further outwardly from the opening in the housing so that the first portion is rotatable relative to the housing and the first portion may be rotated to a selected position and returned to the first axially connected position of the first and second portions of the latch.07-30-2009
