Abstract: An adaptor includes a body defining a longitudinal axis, and a transverse axis that is normal to the longitudinal axis. The body also has a leading portion defining a lock receiving recess extending transversely at least partially through the leading portion. The leading portion defines at least one linear portion in the lock receiving recess that is configured to engage the power locking device.

Abstract: A magnetic wear device including a resilient member and a magnetic member for protecting a wear surface on a material handling device. The resilient member consisting of an upper portion and a lower portion integrally formed together. The upper portion having a top exterior surface, and the lower portion having a bottom surface for contacting with a wear surface on a material handling device. The bottom surface of the lower portion being formed with a recess for receiving and coupling the magnetic member to the resilient member. The magnetic member having an outer magnetic surface for releaseably securing the magnetic member and the resilient member to the wear surface of the material handling device. The magnetic wear device further including a shear plate having an outer edge and an inner circular edge. The outer edge is constructed with one or more notched edges and the inner circular edge defines an aperture for at least partially receiving the resilient member and the magnetic member therein.

Abstract: A system and method for molecular dynamic simulation includes a database for storing data pertaining to at least one biomolecular system, a memory device for storing instructions for performing at least one algorithm having an electrostatic interaction calculating function and a multiple time step function, and subdividing forces on a basis of distance over which the forces act, and a processor for processing the data by executing the instructions in order to propagate the biomolecular system from a first set of coordinates to a second set of coordinates. The system and method significantly speed up the molecular dynamics simulation of biomolecular systems in which there are long-range and short-range electrostatic interactions and in which there are fast and slow motions, and make practicable the simulation of large protein solutions and thus, can be used to simulate protein folding and the binding of substrates to protein molecules.

Abstract: A medical rescue system comprises a pressure responsive valve system that is configured to permit respiratory gases to be actively passed through the valve system and to prevent the flow of respiratory gases through the valve system until a threshold negative intrathoracic pressure is exceeded. The valve system further includes a swivel mount, and a ventilation tube is provided to be pivotally coupled to the swivel mount in the valve system. A headrest may also be provided to elevate and tilt the patient's head back and away from the patient's chest to assist in ventilating the patient. The communication device may be stored in the headrest to send communication signals to a remote receiver for emergency service.
