Abstract: A joint for use in an orthopedic brace has a bottom plate and at least one arm bar rotatably mounted on the bottom plate for allowing unlimited rotation of the joint within a range. At least one shaft is coupled to the arm bar. A top plate is slideably mounted along the shaft in opposition to the bottom plate. A lever mounted on the top plate engages the plates to limit the rotation of the joint to a preset angle. The lever further adjusts the rotation of the joint from unlimited rotation within the range to limited rotation within the range without resetting the preset angle.

Abstract: A computer system utilizes a single computer to test the operability of an application which also runs on the same computer. The computer system comprises a processor and a multi-tasking operating system, which is able to execute programs asynchronously and independently of each other in logical environments called sessions. A test case program executes during a first session, and tests an applications program which executes in a second session on the same computer system independently of the test case. The test case program includes commands to input keystrokes to the application under test for processing by the application under test. A test program reads the keystroke and the command from the test case and packetizes the keystroke and command. The test program also runs during the first session. A communication program runs on the processor during a second session and communicates the packetized keystroke and command to the operating system for input to the application under test.
