Abstract: A frictionless electronic safety actuator (100) for use in an elevator system, which includes at least one electromagnet (110), and a magnetic plate (120) attached to a connection arrangement (190). The connection arrangement (190) is configured to connect the magnetic plate (120; 220) to a linkage (80) that is actuatable so as to move a safety brake (24) into frictional engagement with an elevator guide rail (20). The at least one electromagnet (110) is operable to selectively produce a magnetic force which acts upon the magnetic plate (120) to displace the magnetic plate (120) and thereby move the connection arrangement (190) to actuate the linkage (80) without the magnetic plate (120) coming into frictional engagement with the elevator guide rail (20).

Abstract: Iodonium salt initiator and processing-free thermally sensitive plate precursor containing thereof, and processing-free thermally sensitive plate and use thereof, At least one of two para positions of two benzene rings of the iodonium salt initiator is an alkene group containing a carbon or nitrogen or oxygen atom and a double bond at an end. The alkene group can increase a steric hindrance of the iodonium salt, improves compatibility of the iodonium salt, the thermosensitive resin and the crosslinkable prepolymer, reduces the surface migration of the iodonium salt in the imaging layer and improves the initiation efficiency. During the laser imaging, a double bond contained in a residual end of the iodonium salt can perform a crosslinking reaction with the thermosensitive resin and the crosslinkable prepolymer, and thus reduces damage to the imaging layer caused by small molecules.

Abstract: The invention is directed to an endoluminal device (10) comprising a stent (20) and a sleeve (30). In one embodiment, the endoluminal device is implanted in a portion of the gastrointestinal tract. The stent has a first region (22) and a second region (24) where the first and second regions provide different levels of radial force. The first region is made from a plurality of first wires having a first diameter and the second region is made from a plurality of second wires having a second diameter which is smaller than the first diameter. In other embodiments, the endoluminal device has at least one engagement mechanism (60) engaging the stent to the sleeve, the endoluminal device to a body lumen, and any combination thereof. In at least one embodiment, the endoluminal device has a wall with at least one opening therein.
