  • Communication and control topology for efficient testing of sets of devices
    Patent number: 9678159
    Abstract: A master controller includes: an interface to a CPU, an input port configured to receive a digital signal, and an output port configured to transmit a digital signal. Slave controllers each include: an interface to a device, an input port configured to receive a digital signal, and an output port configured to transmit a digital signal. A first chain bridge includes: a first set of input and output ports that couple the first chain bridge to a first chain of nodes each coupled to neighboring nodes by conductor paths in a closed loop, where the nodes of the first chain include the master controller, and a second set of input and output ports that couple the first chain bridge to a second chain of nodes each coupled to neighboring nodes by conductor paths in a closed loop, where the nodes of the second chain include multiple slave controllers.

  • Hardware and Software Association and Authentication
    Publication number: 20130254906
    Abstract: Authentication and association of hardware and software is accomplished by loading a secure code from an external memory at startup time and authenticating the program code using an authentication key. Access to full hardware and software functionality may be obtained upon authentication of the secure code. However, if the authentication of the secure code fails, an unsecure code that provides limited functionality to hardware and software resources is executed.
