Patent number: 7536663Abstract: In one embodiment, a plurality of signals are sequentially driven onto a signal path. Each of the signals has a pulsewidth defined by a trigger edge and a sensor edge, and at least some of the signals having different pulsewidths. After driving each signal, the signal is sampled at or about a timing of the signal's sensor edge to thereby characterize the signal's sensor edge. The sensor edge characterizations corresponding to the different signals are then analyzed to quantify a timing error induced by an impedance variation of the signal path.Type: GrantFiled: February 25, 2005Date of Patent: May 19, 2009Assignee: Verigy (Singapore) Pte.

Patent number: 7251798Abstract: In one embodiment, each of a plurality of stimulus signals is sequentially driven onto a number of stimulus signal paths. Each of the plurality of stimulus signals has a trigger edge. As each stimulus signal is driven onto the number of stimulus signal paths, a victim signal having a sensor edge is driven onto a victim signal path. After driving a corresponding stimulus and victim signal, the victim signal is sampled at or about a timing of the signal's sensor edge to thereby characterize the signal's sensor edge. The sensor edge characterizations corresponding to the different stimulus signals are then analyzed to quantify a timing error induced by crosstalk between the victim signal path and one or more of the stimulus signal paths.Type: GrantFiled: February 25, 2005Date of Patent: July 31, 2007Assignee: Verigy (Singapore) Pte.

Patent number: RE36738Abstract: A tilting member has a force bearing portion to which operating force is applied, and a supported surface. A supporting member has a supporting projection with which the supported surface of the tilting member may come in contact. When the operating force is applied to the tilting member, the tilting member tilts with respect to the supporting member. The supporting member supports the tilting member at a supporting point where the supporting projection of the supporting member is in contact with the supported surface of the tilting member, about which supporting point the tilting member tilts. The tilting of the tilting member, with respect to the supporting member, establishes a predetermined electrical contact.Type: GrantFiled: February 3, 1997Date of Patent: June 20, 2000Assignee: Sega Enterprises, Ltd.Inventors: Hiroshi Matsumiya, Takeki Sugiyama
