Publication number: 20230376831Abstract: Systems and methods are provided for interpreting a correlation model that predicts a correlation between a pair of data corresponding to a pair of incident tickets using an interpreter model. The correlation model includes a Siamese Network including a plurality of neural networks. The interpreter model, trained by using training data, represents a student model (a glass-box model) while the correlation model, trained using the training data, represents a more complex teacher model (a black-box mode) of a teacher-student model. The present disclosure generates global feature importance scores based on the trained interpreter model, which indicates a degree of influence of a feature compared to other features in incident data in determining correlations, to generate additional training data emphasizing influential features and to retrain the correlation model.Type: ApplicationFiled: May 17, 2022Publication date: November 23, 2023Applicant: Microsoft Technology Licensing, LLCInventors: Jimmy Chi Kin WONG, Rakesh J.

Patent number: 11510723Abstract: Tumor ablation devices and related systems and methods are disclosed. Some tumor ablation devices include an RF energy delivery probe with two conductors and one or more thermocouples. The thermocouple measures a temperature at a location on one of the conductors. A generator can produce a current to be conducted between the first conductor and the second conductor via tissue within a desired ablation region. The ablation regions created by the RF energy delivery probe are symmetric about poles of the first conductor and the second conductor. A distal portion of the RF energy delivery probe may articulate, enabling a user to position the RF energy delivery probe in a proper position to ablate the tumor. The thermocouples may be disposed on a flexible or wired thermocouple circuit that is disposed between insulators.Type: GrantFiled: November 7, 2019Date of Patent: November 29, 2022Assignee: DFine, Inc.Inventors: Joshua Defosset, Nate Shirley, Eric Wong, Craig Purdy, Oleg Yurchak, Jimmy Chi-Yun Chan

Patent number: 9930722Abstract: Various aspects of the present disclosure provide for conditionally disabling discontinuous reception (DRX). For example, DRX may be disabled if there is a loss of DRX synchronization, a loss of signal radio bearer traffic, a poor radio frequency condition, a low signal-to-interference ratio estimate, a low transmit power condition, or a drop in transmit power. Various aspects of the present disclosure provide for determining that an access terminal and the network are not in synchronization (e.g., DRX synchronization), and attempting to re-synchronize the access terminal and the network. In cases where a loss of DRX synchronization involves one entity having DRX enabled while another entity has DRX disabled, DRX may be temporarily disabled until synchronization is restored. In cases where a loss of DRX synchronization involves different entities using different subframe indices, the subframe index used by one of the entities may be changed to restore synchronization.Type: GrantFiled: February 17, 2015Date of Patent: March 27, 2018Assignee: QUALCOMM IncorporatedInventors: Shashank Vishwanatha Maiya, Jimmy Chi-Wai Chui, Wei Zhang, Sharif Ahsanul Matin, Nate Chizgi

Patent number: 9344217Abstract: UEs are adapted to facilitate reconstruction of a segment of corrupted bits. According to one example, a UE can receive a control channel transmission such as a HS-SCCH transmission. The control channel transmission may include a plurality of information bits and a plurality of cyclic redundancy check (CRC) bits. The UE may further determine that a contiguous segment of the received information bits is corrupt. The UE may accordingly utilize the uncorrupted information bits and CRC bits to reconstruct the corrupt information bits. In some instances, the UE may utilize the uncorrupted bits to reconstruct the corrupt information bits using a new generator polynomial. In other instances, the UE may utilize the uncorrupted bits to reconstruct the corrupt information bits using the original generator polynomial.Type: GrantFiled: March 20, 2014Date of Patent: May 17, 2016Assignee: QUALCOMM IncorporatedInventors: Jimmy Chi-Wai Chui, Nate Chizgi, Abhinav Gupta, Amith Vikram Chincholi, Chulong Chen

Publication number: 20150139000Abstract: CQI is enhanced in fast fading and/or poor RF scenarios. For example, in the event a fast fading condition and/or a poor RF condition is detected at a UE, a CQI value is increased by a defined delta. The UE reports this higher CQI value to a serving access point (e.g., base station) as long as the channel condition prevails this way such that a corresponding increase in throughput may subsequently be seen at the UE.Type: ApplicationFiled: June 6, 2014Publication date: May 21, 2015Inventors: Sharif Ahsanul Matin, Jimmy Chi-Wai Chui, Je Woo Kim, Sagar Bharatkumar Shah, Rajat Sharma, Aashish Poudel

Publication number: 20150097098Abstract: A steel coil protection structure supports a steel coil stably, keeping it from dropping to affect road safety or endanger lives of operators. The protection structure includes a bottom seat, foundation units, side seats and carrier blocks. The bottom seat is a quadrilateral plate and each end side thereof is the foundation unit, forming a gap between the foundation units. Each end side of the foundation unit is the side seat, tilted deliberately toward a center to form a bevel. An exterior side of the side seat includes a recess, facilitating users to transport the protection structure. The carrier blocks are fixed above the side seats and have an excellent slide-proofing and vibration-absorption effect to truly locate the steel coil on the protection structure, preventing the steel coil from sliding to cause danger.Type: ApplicationFiled: October 3, 2013Publication date: April 9, 2015Inventor: Jimmy CHI
