A sleeve heater has an electrical and generally cylindrical heater coil centered on an axis and shaped to fit over a part to be heated, a radially compressible and generally cylindrical inner sleeve snugly coaxially surrounding the heater coil, and a radially generally inextensible and generally cylindrical outer sleeve fitted coaxially over the inner sleeve. The cover is rotatably fixed relative to the base for rotation about a center axis between a lock position and an unlock position. Accordingly, the processor that, for example, completes a current frame relay is stalled until the other processor has completed its rendering function for a particular odd line, even line, entire frame or partial frame as desired. A parallel moving vector estimation unit estimates a parallel moving vector of timing included in the parameter of affine transformation by using an input image of timing from the first camera, an input image of timing from the second camera, and the temporary status information. In diagnostic test mode, the method uses the ATE to 1) provide a second series of scan test patterns to the BIST hardware, and 2) capture raw response data.
