This paper presents the Open-Circuit Deadlock (OCD), a primitive that allows flexible and scalable securization of a JTAG target, from the cell to the system level.

This paper presents the test instruction set architecture (TISA), an invention that can enable scalable interactive testing to leverage the experience of embedded computing. This approach is applied to an 1149.1 system, obtaining a processor able to efficiently handle instrument-based operations.

Starting from an analysis of the accomplishments and shortcomings of the existing approaches, this paper proposes a new description language able to satisfy all the requirements of IJTAG while providing a fresh and sound base for future evolutions.

We describe estimation of the parameters of a manufacturing test and repair model using data available from that test. The model allows imperfect testing and imperfect repair. The principal problem that we address is of parameter identification, given insufficient data, that we address by making conservative assumptions on the property being measured and the associated parameter values. Several cases of commonly occurring test types, in the manufacture of electronic products, are considered.

The authors present two geometric descriptions of the frictional properties of a rigid body sliding on a planar surface. The limit surface from classical plasticity theory, is the boundary of the set of all possible frictional forces and moments that can be sustained by the frictional interface. Zhukovskii's moment function is the frictional moment as a function of the instantaneous center of rotation's location. Both of these descriptions implicitly contain the full relationship between slip motion and frictional load for an object that makes contact governed by a useful class of friction laws that includes Coulomb friction. These surfaces can be used to deduce results concerning the overall frictional motion behavior of rigid bodies, such as the existence of characteristic final slip motion directions.>
