  • Publication number: 20190072461
    Abstract: A system and method for monitoring manufacturing machines that includes a sensor system that monitors a plurality of machines, wherein the sensor system is comprised of a set of current transformers, and wherein the set of current transformers transform electric currents to the plurality of machines into electric signals; an activity processing engine, wherein the activity processing engine generates diagnostic metrics from the electric signals for each machine from the plurality of machines; and a management platform configured to provide access to diagnostic metrics of the plurality of machines.

  • Patent number: 9106471
    Abstract: An approach includes injecting a plurality of equal amplitude tones across a frequency band. The approach also includes determining frequency response based on the injected tones, determining an imbalance parameter associated with a quadrature down-converter based on the determined frequency response; determining one or more parameters for wideband quadrature compensation based on the determined frequency response, and compensating an input signal based on the determined imbalance parameter and the determined one or more parameters for the wideband quadrature compensation.

  • Patent number: 8054807
    Abstract: A Handover method in a mobile WiMAX network includes sending a list of target BSs for possible HO acquired by an MSS to a serving BS; providing, at the serving BS, a HO request to the target BSs in the list along with an unique identifier identifying the MSS to collect association responses from the target BSs; providing, at the serving BS, the association responses along with the unique identifier to the MSS so that the MSS performs scanning and ranging processes; performing resource reservation for possible HO at the target BSs; setting up service flows at a target BS selected among the target BSs; bi-casting data from the serving BS to the MS and the selected target BS before the connection break with the serving BS; and performing, at the MSS, an initializing procedure to connect with the selected target BS as a new serving BS.

  • Publication number: 20100144353
    Abstract: A Handover method in a mobile WiMAX network includes sending a list of target BSs for possible HO acquired by an MSS to a serving BS; providing, at the serving BS, a HO request to the target BSs in the list along with an unique identifier indentifying the MSS to collect association responses from the target BSs; providing, at the serving BS, the association responses along with the unique identifier to the MSS so that the MSS performs scanning and ranging processes; performing resource reservation for possible HO at the target BSs; setting up service flows at a target BS selected among the target BSs; bi-casting data from the serving BS to the MS and the selected target BS before the connection break with the serving BS; and performing, at the MSS, an initializing procedure to connect with the selected target BS as a new serving BS.
