Patent number: 10055476Abstract: A set of search requests may be analyzed to detect fixed phrases suitable for inclusion in a search index. Sets of candidate phrases may be identified among the search requests. Fixed phrases may be detected among the candidate phrases using statistical techniques, for example, by identifying phrases having a relatively high pointwise mutual information (PMI) with respect to component keywords. Fixed phrase detection may include keyword and/or phrase clustering. Clusters may correspond to topics defined using a latent Dirichlet allocation (LDA) procedure. Fixed phrase detection may include identifying phrases having relatively high PMI within particular clusters.Type: GrantFiled: June 5, 2014Date of Patent: August 21, 2018Assignee: A9.COM, INC.Inventors: Waseem Ahmad, Deepak Jain

Patent number: 9600309Abstract: Methods, apparatus and systems for effecting Virtual Machine (VM) platform communication loopback and enabling user initiated network port failover. Network communications in platforms employing VMs and having multiple network ports accessible to the VMs are configured to be routed such that communications between VMs in the platform are looped back within the platform, thus not require routing through an external switch. This is facilitated via an Intelligent Channel Bonding Driver that dynamically enforces inter-VM traffic to ensure internal loopback within the same physical port. In another aspect, a user is enabled to initiate failover of a network port on a platform employing a Virtual Machine Manager and a plurality of VMs, wherein updated configuration information is sent to disable Virtual Function (VF) drivers associated with the network port.Type: GrantFiled: June 8, 2012Date of Patent: March 21, 2017Assignee: Intel CorporationInventors: Jeff Prawer, James R. Hearn, Waseem Ahmad

Patent number: 8452829Abstract: A feedback module is defined to receive as input a set of data sample signals and a set of reference sample signals. Each of the data and reference sample signals is generated by sampling a differential signal having been transmitted through a FIR filter. The feedback module is defined to operate a respective post cursor counter for each post cursor of the FIR filter and update the post cursor counters based on the received sets of data and reference sample signals. Also, the feedback module is defined to generate a tap weight adjustment signal for a given tap weight of the FIR filter when a magnitude of a post cursor counter corresponding to the given tap weight is greater than or equal to a threshold value. An adaptation module is defined to adapt a reference voltage used to generate the reference sample signals to a condition of the differential signal.Type: GrantFiled: June 23, 2008Date of Patent: May 28, 2013Assignee: Oracle America, Inc.Inventors: Dawei Huang, Dong J.

Patent number: 8381531Abstract: A fuel injector for a gas turbine engine may include a pilot assembly extending along a longitudinal axis. The pilot assembly may be configured to direct a pilot fuel-air mixture to a combustor of the gas turbine engine. The fuel injector may also include a rich catalyst module circumferentially disposed about the pilot assembly. The catalyst module may be configured to simultaneously direct a stream of compressed air and a stream of first fuel-air mixture therethrough without intermixing. The fuel injector may also include a post mix zone disposed downstream of the catalyst module. The post mix zone may be configured to mix the compressed air and the first fuel air mixture to create a main fuel-air mixture. The fuel injector may further include an air swirler disposed downstream of the post mix zone. The air swirler may be configured to direct the main fuel-air mixture to the combustor without intermixing with the pilot fuel-air mixture.Type: GrantFiled: November 7, 2008Date of Patent: February 26, 2013Assignee: Solar Turbines Inc.Inventors: Waseem Ahmad Nazeer, Kenneth Owen Smith, Frank John Ritz

Patent number: 8243866Abstract: An analog baud rate clock and data recovery apparatus includes a first track and hold circuit that delays a received signal by one unit interval to create an odd signal; a second track and hold circuit that delays the received signal by one unit interval to create an even signal; a first comparator circuit; and a second comparator circuit. The first track and hold circuit outputs the odd signal to the first comparator circuit and the second comparator circuit. The second track and hold circuit outputs the even signal to the first comparator circuit and the second comparator circuit. The first comparator adds the odd signal to the even signal and outputs a first potential timing error. The second comparator subtracts the odd signal and the even signal and outputs a second potential timing error signal. A desired timing error signal is derived from the first and second potential timing error signals. The desired timing error signal is used to determine whether signal sampling is early or late.Type: GrantFiled: May 7, 2008Date of Patent: August 14, 2012Assignee: Oracle America, Inc.Inventors: Dawei Huang, Zuxu Qin, Drew G.

Patent number: 7839212Abstract: A two stage fully differential amplifier has been designed which works, in tandem with a TX-FIR, as a linear equalizer at low frequencies, not covered by the TX-FIR, and also acts as a linear amplifier at higher frequencies which are equalized by the TX-FIR. The amplifier as a frequency response which does not attenuate signals frequencies less than one twentieth of baud rate, creates gain peaking ion the region between one twentieth and one tenth of baud rate and maintains flat peak gain up to half of baud rate. Different aspects of the frequency response curve (such as dc gain, max gain and zero frequency) are completely programmable. Also, the differential amplifier has been designed from low power and process, voltage and temperature insensitive frequency response.Type: GrantFiled: December 4, 2008Date of Patent: November 23, 2010Assignee: Oracle America, Inc.Inventors: Dawei Huang, Arif Amin, Waseem Ahmad, Rajesh Kumar, Venkatesh Arunachalam
