Abstract: An exemplary electric strike includes a housing and a keeper pivotally mounted in the housing. The strike also includes a plunger having an extended position and a retracted position, a cage including an aperture, and a locking element movably seated in the aperture. The locking element is engaged with the plunger, and the plunger is structured to urge the locking element radially outward as the plunger moves from an extended position toward a retracted position. The strike also includes a sleeve, a transmission engaged with the sleeve, and a motor drivingly coupled to the transmission. The sleeve is structured to selectively prevent radially outward movement of the locking element and retraction of the plunger. The strike also includes at least one of a lost motion connection and an anti-tamper mechanism.

Abstract: An assembly for adjusting a cable that includes a locking sleeve and an adapter that is connected to the cable. The adapter includes male and female-threaded portions that are coupled together. The locking sleeve is configured to be displaced between engagement and disengagement positions. When in the engagement position, securing devices of the male and female-threaded portions engage inner sections of the locking sleeve in a manner that prevents the male and female-threaded portions from being rotated relative to each other, thereby preventing a change in the length of the adapter so as to prevent an adjustment of the cable. When the cable is to be adjusted, the locking sleeve is displaced to disengagement position such that the securing device of either the male or female-threaded portion is disengaged from the locking sleeve, thereby allowing rotation of the male or female-threaded portions relative to each other.

Abstract: A damping device for an exit device that is configured to resist high velocity movement a latch assembly relative to a baseplate assembly. Pivotal displacement of a bell crank during typical operation of the exit device may cause a protrusion of the bell crank to exert a pulling force on control linkage element that is coupled to a connection link of a latch assembly and a spring damper element of the damper device, thereby operating the latch assembly while also generally by-passing the damping effect of the damping device. When high velocity movement is imparted on an entryway device associated with the exit device, the damper device resists high velocity movement of the latch assembly relative to the baseplate assembly, thereby at least attempting to prevent the latch assembly from moving independently of the baseplate assembly so as to prevent unlatching of a latch of the latch assembly.

Abstract: An imaging system illuminates an object with infrared light to enhance visibility of buried structure beneath the surface of the object, and projects a visible light image of the buried structure onto the surface of the object. The system may include an infrared light source for generating the infrared light and a structure for diffusing the infrared light. The diffusing structure may include one or more layers of diffusing material for diffusing the light. The system further includes a video imaging device for receiving the infrared light reflected from the object and for generating a video image of the buried structure based on the reflected infrared light. The buried structure may be a subcutaneous blood vessel. A calibration procedure is described as well as embodiments for ensuring that the object is maintained in focus at the correct distance.
