Patent number: 12248812Abstract: Systems and methods for adaptively re-adjusting meter rates of processor cores of a multi-core processor having ports grouped in a Link Aggregation Group (LAG) are provided. A method, according to one implementation, includes a step of obtaining a metering allocation setting for a service on each of a plurality of processor cores. The plurality of processor cores is configured to receive data traffic via a plurality of data ports. The data ports are configured to be grouped so as to serve as a single logical port from the perspective of an external component. The method further includes a step of determining an anticipated metering need associated with the service on each of the processor cores. Also, the method performs an adaptive metering procedure that includes automatically adjusting the metering allocation setting for the service based on the respective anticipated metering need.Type: GrantFiled: December 22, 2021Date of Patent: March 11, 2025Assignee: Ciena CorporationInventors: Ashish Gulati, Sumit Hans, Gagan Garg, Jayant Bhardwaj

Patent number: 12189135Abstract: Consistent with the present disclosure, an output of a seed laser is split by a series of first coupler stages and each split portion is provided to a respective laser in an array of secondary lasers to realized injection locking of the laser array. Undesired light output from the secondary laser array back to the seed laser is monitored and the phase of such light is adjusted so that such light is subject to destructive interference and its power is minimized. Accordingly, light output from the secondary laser array back to the seed laser does not degrade the performance of the seed laser. On the other hand, light intended for output from the secondary laser array is combined through a second series of coupler stages and monitored at each stage. The phase of the output of each laser in the array is controlled to equal or be aligned with one another such that laser array outputs constructively interfere with one another. As a result, the combined output power is maximized.Type: GrantFiled: April 2, 2021Date of Patent: January 7, 2025Assignee: Infinera CorporationInventors: Ashish Bhardwaj, Gloria E. Hoefler

Patent number: 11222670Abstract: Various implementations described herein are directed to an implementation of a higher order multiplexer using lower order multiplexers. In an embodiment, the implementation requires a slight modification to the existing circuitry design of the lower multiplexers. A plurality of multiplexers may be coupled with each other such that a common input port and output port is formed. Using an enable signal, only one of the coupled multiplexers may be enabled at a time while the remaining multiplexers are switched off. Therefore, upon receiving a select signal indicating an address of a memory cell, the lower multiplexers coupled together function as a higher order multiplexer in selecting the appropriate column corresponding to the memory cell.Type: GrantFiled: December 10, 2019Date of Patent: January 11, 2022Assignee: Arm LimitedInventors: Lalit Gupta, Nicolaas Klarinus Johannes Van Winkelhoff, El Mehdi Boujamaa, Bo Zheng, Fakhruddin Ali Bohra, Cyrille Nicolas Dray, Ashish Bhardwaj, Durgesh Kumar Dubey

Patent number: 10924969Abstract: A user equipment (UE) registers on a first Public Land Mobile Network (PLMN) and, while in an idle mode, receives a Multimedia Broadcast Multicast Services (MBMS) service. The UE determines whether to perform a periodic network reselection search for a higher priority PLMN while in the idle mode, wherein the UE determines whether to perform the periodic network reselection search based on reception of the MBMS service. The UE may postpone the periodic network reselection search for a period of time while the UE receives the MBMS service in the idle mode. The UE may postpone the periodic network reselection search for a period of time while the UE receives the MBMS service in the idle mode. The UE may interleave the periodic network reselection search with the reception of transmission bursts of the MBMS service, the search being performed on frequencies other than that of the MBMS transmission.Type: GrantFiled: July 25, 2019Date of Patent: February 16, 2021Assignee: Qualcomm IncorporatedInventors: Ashish Bhardwaj, Edward Robert Hall

Patent number: 10517003Abstract: A wireless communication device having a first SIM and a second SIM and a radio frequency (RF) resource including multiple receive chains and at least one transmit chain may detect, during a connection to a first network associated with the first SIM, a start of a communication activity associated with the second SIM that uses one or more transmit chains and one or more of the receive chains. The wireless communication device may determine whether a carrier frequency of a cell serving the network associated with the first SIM is within a downlink frequency range supported by an unused receive chain of the RF resource. If not, the wireless communication device may identify a neighbor cell of the first network with a carrier frequency within a downlink frequency range supported by an unused receive chain of the RF resource, and attempt to camp the first SIM on that neighbor cell.Type: GrantFiled: December 28, 2016Date of Patent: December 24, 2019Assignee: QUALCOMM IncorporatedInventors: Ashish Bhardwaj, Manjunatha Subbamma Ananda, Venkateswarlu Bandaru, Shakti Singh Chauhan
