  • Transient voltage suppressor and method
    Patent number: 8339758
    Abstract: A transient voltage suppressor and a method for protecting against surge and electrostatic discharge events. A semiconductor substrate of a first conductivity type has gate and anode regions of a second conductivity type formed therein. A PN junction diode is formed from a portion of the gate region and the semiconductor substrate. A cathode is formed adjacent to another portion of the gate region. A thyristor is formed from the cathode, the gate region, the substrate, and the anode region. Zener diodes are formed from other portions of the gate region and the semiconductor substrate. A second Zener diode has a breakdown voltage that is greater than a breakdown voltage of a first Zener diode and that is greater than a breakover voltage of the thyristor. The first Zener diode protects against a surge event and the second Zener diode protects against an electrostatic discharge event.

  • System and Method for Determining Fluid Flow of Compressible and Non-Compressible Liquids
    Publication number: 20120278052
    Abstract: A system and method for determining fluid flow of compressible and non-compressible liquids is described. The system may include input means for receiving a model of an object defined as a plurality of cells having a plurality of nodes P, and a processor coupled to a memory. The processor may be configured for: discretizing a partial differential equation (PDE) corresponding to the received model; for each node P: (i) locating all neighbouring cells that share the node P, each of the neighbouring cells having a cell center; (ii) approximating the PDE at the cell center of the neighbouring cells using the discretized PDE; and (iii) updating a solution of the PDE at the node P by using the approximated discretized PDE at all the neighbouring cell centers; and iteratively updating the solution for all the nodes P from an initial guess until a convergence criterion is satisfied.
