Abstract: A system for controlling disparate remote devices includes a control model, the control model providing a standardized interface to a user, the standardized interface providing a plurality of activities. The plurality of activities includes updating access credentials. The control module is configured to and executes commands causing the control module to communicate with a remote device, the remote device providing a remote-control interface having one or more interface types, selected from a list consisting of graphical user interface, command line interface, and menu driven interface. The control module simulates direct user interaction with the remote-control interface, translating a standardized command specifying an activity of the plurality of activities received via the standardized interface to a translated command, the translated command simulating direct user interaction with the one or more interface type.

Abstract: A reciprocating saw blade having a shank with a longitudinal axis which extends from one end of the blade to the other end of the blade and a transverse axis which extends across the width of the blade. A cutting edge is located along one or both longitudinal edges of the shank of the blade, a concave side wall extends along the transverse axis of one side of the blade, a convex side wall extends along the transverse axis of the other side of the blade and the curvature is around the longitudinal axis.

Abstract: Disclosed is an improved centrifuge apparatus for separating substances of varying density and a method of controlling the speed of a rotor of the centrifuge apparatus. A vent-view port is mounted for in-out adjustment within an access aperture formed in a lid of the centrifuge apparatus so as to provide for selective opening of vent holes formed in the vent-view port. In addition to venting, the vent-view port has a sensor mount with a transparent window for receiving a tachometer probe for rotor speed monitoring. Additionally, a desired centrifugal force and a desired accumulative centrifugal force can be entered by a human operator. A control unit adjusts the rotor speed and operational cycle time to meet the inputted desired force values while displaying the actual accumulative centrifugal force at the end of the operation cycle.
