Patent number: 11658885Abstract: The disclosed technology teaches automating evaluation of QoE for data communication services in a wireless network—accessing performance indicators, mappings for the performance indicators to SKQIs in a SKQI parameters table, and mappings for SKQIs to KQIs in an SKQI-to-KQI mapping table. The disclosed method includes configuring first and second functions that, respectively, roll up performance indicators into SKQIs based on parameters stored in the SKQI parameters table to calculate SKQI scores and weights, and roll up SKQIs into KQIs and QoE based on parameters stored in SKQI-to-KQI and SKQI-to-QoE mapping tables, to calculate KQI and QoE scores. Also disclosed is generating first SQL statements that invoke the first function to calculate the SKQIs and second SQL statements that invoke the second function to calculate KQIs and QoE, storing generated first and second SQL statements in non-volatile storage and calculating KQIs and QoE using the automatically generated SQL statements.Type: GrantFiled: October 1, 2018Date of Patent: May 23, 2023Assignee: SPIRENT COMMUNICATIONS, INC.Inventors: Swetha Pendyala, Peter Peng, Ovidiu Reghis, Marius Adamut

Publication number: 20200099572Abstract: The disclosed technology teaches alerting a network operator to deteriorated wireless network conditions with granularity and reduced false alerts, including receiving tracked performance indicators (KPIs) for multiple components of voice, data and messaging and accessing a mapping for combining the performance indicators into quality sub-indicators for individual users and into key quality indicators (KQI) for the individual users. This includes smoothing the current KQI measures of performance over time to reduce the impact of brief transitory events, accessing a weekly profile of KQIs, and comparing KQIs for a current time window to past KQIs for a corresponding time window for the individual users operating mobile devices in part of the cellular network that is a focus of interest. Based on the comparing, the disclosed technology includes generating alerts that report out-of-range current KQIs within the focus of interest that are persistently out-of-range for longer than a configurable time.Type: ApplicationFiled: September 20, 2018Publication date: March 26, 2020Applicant: SPIRENT COMMUNICATIONS, INC.Inventors: Peter PENG, Marius ADAMUT, Meenal AGARWAL, Brion FEINBERG, Ovidiu REGHIS, Thomas RUSSO

Publication number: 20090133693Abstract: A water-sealing diving-use snorkel without generating a vacuum suction force includes a diving-use snorkel unit connected with an air intake-ventilation nozzle unit comprising an air intake-ventilation pipe, a nozzle plate, at least one housing, a water-sealing membrane, and a float, being orderly sheathed. The water-sealing membrane and the float are sheathed respectively on strip units of the nozzle plate, allowing the water-sealing membrane and the float to slide freely on rails of the strip units. When a water level sinks, a small amount of air can enter into the snorkel unit from a notch on a leak-proof washer below the nozzle plate; therefore, no vacuum suction force will be formed to suck the water-sealing membrane, such that a sense of fear that a user feels unable to breathe can be eliminated.Type: ApplicationFiled: November 23, 2007Publication date: May 28, 2009Inventor: Peter Peng

Publication number: 20050229318Abstract: The present invention refers to an improvement in a bed mattress containing signal means for the identification of the correct mattress position for any day of the year, making it viable for the implementation of a rotation program designed for increasing the useful life of this product. The improved mattress contains signal means for indicating which one of the four possible mattress positions is the correct one at the date of inspection. For example, in a monthly rotation program, if the current month is not indicated on the mattress in a directly readable form, the mattress should have its position altered, until the correct month is directly readable on the mattress. In this manner, the four positions of the mattress are uniformly used, expanding significantly the useful life of the mattress, in comparison with another that is not rotated, that is rotated sporadically or that is rotated in a random fashion.Type: ApplicationFiled: April 15, 2004Publication date: October 20, 2005Inventor: Peter Peng
