Publication number: 20110038259Abstract: Methods and apparatuses, including computer program products, are described for priority policing of requests with deferred determination of priority level. The method includes directing each packet in a data stream to a policer. The method also includes determining whether to allow, reject, or conditionally pass each packet through the policer based on parameters associated with the policer. The method also includes directing each packet conditionally passed by the policer to a classifier associated with the policer. The method also includes determining, by the classifier, a priority value of each packet received from the policer. The method also includes directing, by the classifier, each prioritized packet to the policer. The method also includes determining whether to allow or reject each prioritized packet through the policer based on the priority value.Type: ApplicationFiled: February 9, 2010Publication date: February 17, 2011Applicant: Sonus Networks, Inc.Inventors: Shaun Jaikarran Bharrat, Kevin John Pilotte, Tolga Asveren, Vijay Subramanian, Vince Hung-Kwan Choy

Publication number: 20060195328Abstract: A computerized method that provides a Web page having control structures for gathering behavioral biometrics. The method can receive behavioral biometric data in accordance with the control structures and in accordance with interactions of a user with the Web page. Additionally, the method can compare the received behavioral biometric data with at least one set of previously established values. The user can be profiled based upon comparison results. This profiling can affect the manner in which Web pages are provided to the user as well as the content contained therein.Type: ApplicationFiled: February 15, 2005Publication date: August 31, 2006Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Subil Abraham, Jason Gonzalez, Hung Kwan, Mathews Thomas

Patent number: 5707014Abstract: A water jet cleaner for the underside of a vehicle. A plurality of jets are directed upwardly from a spray head which is mounted on a longitudinal member positioned closely to the ground on which the vehicle is resting. A handle is attached to the longitudinal member and wheels are mounted to the frame and the longitudinal member to allow manual reciprocal movement of the cleaner beneath the vehicle by an operator. The jets are angularly adjustable such that the cleaner may also be used to clean the surface itself such as a driveway.Type: GrantFiled: April 3, 1995Date of Patent: January 13, 1998Assignee: Continental Innovation & Technology Inc.Inventors: Ying-Chiu Chan, Daniel Lo, Kenneth Hung Kwan Ma
