  • Patent number: 11870381
    Abstract: A Pole Phase Modulated (PPM) nine-phase induction motor drive may be used in gearless electric vehicle applications. A single stator winding multiphase induction motor may deliver variable speed-torques by varying the number of phases and poles with respect to a multiphase power converter. A multilevel inverter controlled with carrier phase shifted space vector pulse width modulator (PWM) may further improve the PPM based multiphase induction motor (MIM) drive with respect to efficiency, torque ripple, and direct current (DC) link utilization. To operate the PPM based MIM drive smoothly in different pole phase combinations, indirect field oriented vector control may used.

  • Patent number: 10931582
    Abstract: A network appliance deployed in a visibility fabric may intelligently drop certain low priority traffic to avoid indiscriminate dropping of data packets across all flow maps during periods of high congestion. More specifically, the network appliance may determine the data packets of a flow map should be dropped based on priority measures assigned on a per-flow map basis. Such a technique enables the network appliance to drop low priority traffic and forward high priority traffic downstream. Also introduced herein are techniques for metering traffic in order to gain better control over the traffic that is forwarded to an egress port of a network appliance. Because a network tool connected to the egress port can become easily overwhelmed, the network appliance may filter the traffic based on the priority of the flow maps to ensure that the network tool does not receive more traffic than can be handled.

  • Patent number: 10855570
    Abstract: A network appliance described herein allows the user to selectively forward the flow of packets received through a network port, to a particular egress port. The network appliance creates virtual ports, which can be assigned to the one or more egress ports. The network appliance assigns the flow of packets to the one or more virtual ports in the network appliance. The network appliance decides a forwarding treatment to be applied to the flow of packets, for forwarding the flow of packets to the egress tool ports, based on the virtual port to which the flow of packets is assigned and based on a detected network characteristic. The forwarding treatment can be a decision to drop the flow of packets, or to send the flow of packets to the egress port assigned to the virtual port.

  • Patent number: 10266564
    Abstract: The present invention relates to the cationic lipid cordiaroimide hybrid compounds of formula I. The present invention provides a process for preparation of these compounds is also being elaborated. The compounds described provides anticancerous activity against cell lines including PC-3 (prostate cancer), HepG2 (liver cancer), MCF-7 (breast cancer) and NIH-1/3T3 (non cancer cells. The compound was also capable of inducing caspase-3 mediated apoptosis in HepG2 cells by arresting the cell cycle in the G1 phase. Furthermore, the compound exhibited DNA ligase I inhibition. The present class of cationic lipid cordiarimide hybrids is likely to find specific use in developing novel targeted therapies for liver and prostate cancers.

  • Publication number: 20070127257
    Abstract: A headlamp assembly for a motor vehicle having a light source, a chamber that receives the light source and a cooling channel for removing heat from the chamber. A conductive wall and an insulating wall cooperate to define the chamber and the channel. The conductive wall has a substantially higher thermal conductivity than the insulating wall to promote the heat exchange between the chamber and the cooling channel and to reduce heat exchange between the cooling channel and the relatively hot engine compartment.
