Patents by Inventor Vinh T. Vuong

Vinh T. Vuong has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Multiple source fan control with override
    Patent number: 7196903
    Abstract: An electronic system may comprise a variable speed fan, a first source coupled to the fan, and a second source coupled to the fan. Either of the first or second sources may control the speed of the fan.
    Type: Grant
    Filed: April 4, 2003
    Date of Patent: March 27, 2007
    Assignee: Hewlett-Packard Development Company, L.P.
    Inventors: Vinh T. Vuong, Stephen M. Zaudtke, Raghavan V. Venugopal
  • Multi-mode SCSI backplane and detection logic
    Patent number: 6901458
    Abstract: The present invention includes a multi-mode SCSI backplane and a detection logic that is used in conjunction with the backplane. In this invention, the SCSI backplane can be configured in different modes, included simplex mode and duplex mode. The detection logic can also detect when an illegal configuration is connected to the SCSI backplane and indicate the presence of the illegal configuration by triggering a light emitting diode (LED) or some other indicating mechanism. The detection logic is implemented with a handful of cost-effective field effect transistors (FETs), resistors and LEDs and no additional IC logic gates or Programmable Array Logic (PAL) is necessary.

  • System and method for detecting an operationally impermissible configuration
    Publication number: 20040153851
    Abstract: An electronic system includes logic that couples to connectors and receives signals from the connectors. The logic may also detect the presence of an operationally impermissible configuration of said electrical cables based on said signals.
