20100138709METHOD AND APPARATUS FOR DELAY FAULT COVERAGE ENHANCEMENT - A hybrid clocking scheme for simultaneously detecting a b-cycle path-delay fault in a b-cycle (false) path and a c-cycle path-delay fault in a c-cycle (false) path using at least n+1 at-speed clock pulses during a capture operation in a clock domain in a scan design or a scan-based BIST design, where 1<=b<=c<=n. The scan design or BIST design includes multiple scan chains, each scan chain comprising multiple scan cells coupled in series. The design includes one or more clock domains each running at its intended operating frequency or at-speed. The hybrid clocking scheme comprises at least one at-speed shift clock pulse or one at-speed capture clock pulse immediately followed by at least two at-speed capture clock pulses during the capture operation to simultaneously detect the b-cycle path-delay fault and the c-cycle path-delay fault within the clock domain.06-03-2010

20110080301POWERLINE NETWORK SYSTEM HAVING DATA RELAY FUNCTION - A powerline network system having data relay function includes a plurality of power monitoring zones mutually connected with a powerline network and at least one repeater. Each of the power monitoring zones has at least one power monitoring device. The repeater is connected with each power monitoring device in two adjacent power monitoring zones through powerlines and has a first and a second relay units. The first and second relay units employ two different sets of transmitting and receiving bands to fetch data contained in powerline signals transmitted by each power monitor in adjacent power monitoring zones. The data are received by a relay unit are modulated with different transmitting band and then transmitted to powerlines of another power monitoring zone. The repeaters are not required to be serially connected to the powerlines, and incorrect data read can be also eliminated.04-07-2011
