Patent number: 10601414Abstract: A bias generator and a method for generating a bias voltage are presented. The bias generator is for use with an electronic circuit comprising a first switch coupled in series with a second switch. The bias generator is adapted to generate a reference voltage, a first bias voltage, and a second bias voltage. The second bias voltage is based on the reference voltage. After applying the first voltage to the first switch and the second voltage to the second switch, the bias generator controls a voltage across the first switch. The bias generator may be adapted to set a value of the reference voltage to control the voltage across the first switch. For instance, the reference voltage may be set to a fix value so that the voltage across the first switch is maintained at a constant value.Type: GrantFiled: June 7, 2018Date of Patent: March 24, 2020Assignee: Dialog Semiconductor B.V.Inventors: Zhi Mou, Mohammad Hanif, Mahbub Reja, Shobak Kythakyapuzha

Patent number: 9356859Abstract: Techniques for reducing the latency in performing a failover from a protected connection to its backup connection when a network event is detected affecting the protected connection. In an MPLS network, techniques are provided for failing a protected LSP to a backup LSP in a fast and efficient manner. In one embodiment, the faster failover is facilitated by storing protected LSPs and their backup LSPs information in the data plane, such as locally on a linecard.Type: GrantFiled: August 14, 2012Date of Patent: May 31, 2016Assignee: Brocade Communications Systems, Inc.Inventors: Mohammad Hanif, Dilip Kumar, Minjie Dai, Lisa Hong Nguyen, Sundeep Kumar Singh

Patent number: 8830822Abstract: Techniques for configuring a local repair connection for a protected connection including determining a path for the local repair connection. The path traversed by a local repair connection starts at a node in the path associated with the protected connection and ends at a merge point node in the path associated with the protected connection that is downstream from the start node. In one embodiment, the merge point node may even be more than two hops downstream from the start node in the path associated with the protected connection. The local repair path may include zero or more nodes that are not included in the path associated with the protected connection. Techniques are also described for optimizing the path associated with a local repair connection.Type: GrantFiled: October 14, 2011Date of Patent: September 9, 2014Assignee: Foundry Networks, LLCInventors: Mohammad Hanif, Ivy Hsu

Patent number: 8599681Abstract: Techniques for computing a path for a local repair connection to be used to protect a connection traversing an original path from an ingress node to an egress node. The computed path originates at a node (start node) in the original path and terminates at another node (end node) in the original path that is downstream from the start node. A Constraint Shortest Path First (CSPF) algorithm may be used to compute the path. The computed path is such that it satisfies one or more constraints and does not traverse a path from a first node in the original path to a second node in the original path, wherein the first and second nodes are upstream from the start node in the original path and the second node is downstream from the first node in the original path. A local repair connection may then be signaled using the computed path.Type: GrantFiled: December 20, 2012Date of Patent: December 3, 2013Assignee: Foundry Networks, LLCInventor: Mohammad Hanif

Patent number: 8165032Abstract: Techniques for dynamically establishing and configuring a liveliness detection session for a local repair connection of a connection. In one set of embodiments, a signaling message is received at a node configured to maintain a local repair connection for a connection. A configuration parameter is identified in the signaling message, where the configuration parameter pertains to a liveliness detection mechanism or protocol. A liveliness detection session is then established for the local repair connection based on the configuration parameter.Type: GrantFiled: March 27, 2009Date of Patent: April 24, 2012Assignee: Brocade Communications Systems, Inc.Inventors: Mohammad Hanif, Lisa Hong Nguyen

Patent number: 7783321Abstract: A cell phone device having a camera, an imaging unit and a display unit, which are joined with each other. The imaging unit and the display unit may be separated and used in a separated state. A display housing includes the display unit, a speaker, and a microphone. A keypad housing includes the imaging unit. The display housing and the keypad housing each include a local communication IF unit for performing wireless communication and a battery for supplying power to each function block. When the display housing and the keypad housing are separated, the image generated by the imaging unit is output to the display unit via the local communication IF units. A recording instruction is then generated by operating the display housing while checking the image on the display unit.Type: GrantFiled: December 11, 2006Date of Patent: August 24, 2010Assignee: Freescale Semiconductor, Inc.Inventors: Sadeque Mohammad Hanif, Ehsan Ui Islam, Masanori Tokunaga

Publication number: 20100112945Abstract: An electronic control device transmits a function control signal within a predetermined area. Other electronic devices within the predetermined area receive the function control signal. The function control signal initiates a control program in an electronic device in the predetermined area that adjusts one or more user setting conditions of the electronic device, such as audio volume level, display brightness level, etc. The original user setting conditions are returned to their prior values when the device exits the predetermined area or otherwise stops receiving the function control signal.Type: ApplicationFiled: August 5, 2009Publication date: May 6, 2010Applicant: FREESCALE SEMICONDUCTOR, INCInventor: Sadeque Mohammad Hanif

Patent number: 6141677Abstract: A method and system for processing active AFP sessions by a multithreaded file system process. The file server is coupled to entities on a network, wherein an open AFP session is created when the file server and an entity on the network establish communication, and an active AFP session is created when an AFP session has a pending request. The method and system comprises monitoring the file server for active AFP sessions. When a first active AFP session having at least one AFP request becomes available, the method and system assigns a first one of the threads to the first active AFP session for processing. The method and system preempts the processing of the first active AFP session by the first one of the threads when additional active AFP sessions are available so that the first one of the threads becomes available to process additional active AFP sessions, whereby equal processing time is provided to each one of the active AFP sessions.Type: GrantFiled: October 13, 1995Date of Patent: October 31, 2000Assignee: Apple Computer, Inc.Inventors: Mohammad Hanif, Kazuhisa Yanagihara
