Patents by Inventor Carrell W. Ewing

Carrell W. Ewing 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).

  • Patent number: 7010589
    Abstract: An SNMP network comprises a power manager with an SNMP agent in TCP/IP communication over a network with an SNMP network manager. The power manager is connected to control several intelligent power modules each able to independently control the power on/off status of several network appliances. Power-on and load sensors within each intelligent power module are able to report the power status of each network appliance to the SNMP network manager with MIB variables in response to GET commands. Each intelligent power module is equipped with an output that is connected to cause an interrupt signal to the network appliance being controlled. The SNMP network manager is able to test which network appliance is actually responding before any cycling of the power to the corresponding appliance is tried.

  • Patent number: 6711613
    Abstract: An SNMP network comprises a power manager with an SNNP agent in TCP/IP communication over a network with an SNMP network manager. The power manager is connected to control several intelligent power modules each able to independently control the power-on/off status of several network appliances. Power-on and load sensors within each intelligent power module are able to report the power status of each network appliance to the SNMP network manager with MIB variables in response to GET commands. Each intelligent power module is equipped with an output that is connected to cause an interrupt signal to the network appliance being controlled. The SNMP network manager is able to test which network appliance is actually responding before any cycling of the power to the corresponding appliance is tried.

  • Patent number: 5949974
    Abstract: A SNMP network comprises a power manager with a SNMP agent in TCP/IP communication over a network with a SNMP network manager. The power manager is connected to control several intelligent power modules each able to independently control the on/off power to several inter-networking devices in an equipment rack at a common remote node, e.g., a point-of-presence site. Power-on and load sensors within each intelligent power module are able to report the power status of each inter-networking device to the SNMP network manager with MIB variables in response to GET commands. The SNMP network manager is further able to reboot each inter-networking device by cycling the power on/off to its respective intelligent power module with the SET command provided in conventional SNMP management applications.

  • Patent number: 5506573
    Abstract: A method for sensing the on/off status condition of a power switch in an appliance includes applying a series of alternating current (AC) voltage pulses to an appliance with an on/off switch that are synchronized to a source of AC power, sensing the presence of any series of AC current pulses that result if said appliance switch is closed, analyzing any AC current pulses detected in the step of sensing to determine if they resulted from the application of the AC voltage in the step of applying, and outputting an on/off status indication for the appliance switch.
