Abstract: A dogging mechanism for an exit device may include a camming element that is configured to rotate between an undogged position and a dogged position. The dogging mechanism may include a first linkage operatively coupled to a latch of the exit device and a second linkage operatively coupled to the camming element. The first linkage may be fixed to the camming element such that movement of the camming element between the undogged position and the dogged position moves the latch between a latched position and an unlatched position, respectively. The camming element may include at least one slot that is at least partially curved, and the slot may receive a pin of the second linkage such that the slot is movable relative to the second linkage to move the camming element between the undogged and dogged positions.

Abstract: A dampener for an exit device may be disposed between a portion of an exit device actuator and an exit device chassis so that the dampener dampens vibrations to reduce noise of the exit device and/or inhibit unintentional movement of the actuator to an actuated position. The dampener may be composed at least partially of a viscoelastic material.

Abstract: A pull handle may include a chassis, a latch disposed at least partially in the chassis, a thumb turn, and a dogging fastener movably disposed on the thumb turn. The thumb turn may be rotatable between a locking position and an unlocking position, where the thumb turn is coupled to the latch such that when the thumb turn is in the locking position the latch is in an extended position and when the thumb turn is in the unlocking position the latch is in a retracted position. The dogging fastener may be configured to move between a dogging position and an undogging position, where in the dogging position the dogging fastener engages the chassis to inhibit rotation of the thumb turn.

Abstract: A door pull may be arranged to be operated with a foot or a tool close to the floor. The door pull may include a central portion allowing a user to actuate a door by bringing the foot or the tool in contact with the door pull. The door pull may further include a central portion which includes a serrated top edge, configured to make ergonomic and comfortable contact with a sole of a shoe, and a smooth lower edge, configured to make ergonomic and comfortable contact with a toe box of a shoe.

Abstract: A retrofit latch adapter is configured to replace a pre-existing roller head latch assembly of a pre-existing exit device. The retrofit latch adapter may include a flat latch head that may provide additional security for a door compared with the pre-existing roller head pre-existing latch assembly.

Abstract: An exit device comprises an inner door handle adapted to be mounted to a door for movement relative to the door from a first position to a second position. A pair of brackets are adapted to be operatively connected between the respective ends of a horizontal portion and a vertical portion of the door handle. Each bracket comprises a first bracket member secured to the door handle, a second bracket member adapted to be secured to the door, and a pin for joining the first bracket member and the second bracket member for rotation about an axis through the pin. The first bracket member and the second bracket member pivot relative to one another when the door handle moves between the first position and the second position.

Abstract: A door entry system for operating a door using a wireless transmitter device containing identification credentials of a user. The system includes a door operable by an uncoupling or releasing securing mechanism, a door controller capable of operating the uncoupling or releasing securing mechanism and a door handle for grasping by the user to operate the door, the handle having a cavity, the handle being secured to the door and spaced away from a surface thereof. The system includes a wireless device reader disposed in the handle cavity and a power source connected to the card reader. The wireless transmitter may be presented in the vicinity of the reader in the door handle and, upon verification of the credentials transmitted from the wireless transmitter device, the reader sends a signal to the door controller to uncouple or release the securing mechanism and permit the door to open.

Abstract: An improved image sensor wherein a first micro-lens array comprised of one or more micro-lenses is positioned over a cavity such that incoming light is focused on the photo sensors of the image sensor. The first micro-lens array may collimate and focus incoming light onto the photo sensors of the image sensor, or may collimate incoming light and direct it to a second micro-lens array which then focuses the light onto the photo sensors. A method of fabricating the improved image sensor is also provided wherein the cavity and first micro-lens array are formed by use of a sacrificial material.

Abstract: A method for lining tubular includes positioning an expandable liner in a wellbore at a depth of one or more perforations using a downhole depth locator tool. The expandable liner is expanded in the wellbore to line the one or more perforations.

Abstract: A video content distribution and management system is provided that comprises an event content recorder recording video content associated with an event as an event recording. A workstation stores and edits the event recording to form a composite event review file that is passed to a system manager over a restricted access network. The workstation is located remote from a system manager. The system manager automatically routes the composite event review file to the workstation which enables a user to designate a video segment from the composite event review file. The workstation forms a video clip from the video segment and enables the user to add annotation information to the video clip to form an annotated video clip. The workstation conveys the annotated video clip to the system manager for redistribution.

Abstract: Manufacture of stacked microelectronic devices is facilitated by producing subassemblies wherein adhesive pads are applied to the back surfaces of a plurality of microelectronic components in a batch fashion. In one embodiment, an adhesive payer is applied on a rear surface of a wafer. A plurality of spaced-apart adhesive pads are defined within the adhesive layer. Each adhesive pad may cover less than the entire back surface area of the component to which it is attached. A mounting member (e.g., dicing tape) may be attached to the adhesive layer and, in some embodiments, the adhesive layer may be treated so that the mounting member is less adherent to the adhesive pads than to other parts of the adhesive layer, easing removal of the adhesive pads with the microelectronic components.
