Patent number: 11991313Abstract: The number of agents to which incoming queries to a customer interaction center agent group may be distributed is limited based on skip criteria. The skip criteria is defined based on information associated with agent devices, such as locked status of a device, in-memory status of a client application at the device, or whether a telephone number provisioned for use with the device is from an external public switched telephone network. Agents which fail to satisfy the skip criteria are excluded from distributions of queries to improve wait times for customer interaction center users. Thus, queries are distributed from a queue to agents which satisfy the skip criteria.Type: GrantFiled: August 22, 2022Date of Patent: May 21, 2024Assignee: Zoom Video Communications, Inc.Inventors: Yongxiang Dai, Xu Hua Li, Fengkai Zhang

Patent number: 11810988Abstract: The present disclosure provides an integrated infrared circular polarization detector with a high extinction ratio and a design method thereof. The detector structurally includes a metal reflective layer, a bottom electrode layer, a quantum well layer, a top electrode layer, and a two-dimensional chiral metamaterial layer. Under circularly polarized light with the selected handedness, surface plasmon polariton waves are generated at the interface between the two-dimensional chiral metamaterial layer and the semiconductor, and has a main electric field component aligned with the absorption direction of the quantum wells, thereby enhancing the absorption of the quantum wells. Under circularly polarized light with the opposite handedness, since most of the optical power is reflected, surface plasmon polariton waves cannot be effectively excited, and the absorption of the quantum wells is extremely low, thus realizing the capability of infrared circular polarization detection with a high extinction ratio.Type: GrantFiled: November 10, 2020Date of Patent: November 7, 2023Assignee: Shanghai Institute of Technical Physics, Chinese Academy of SciencesInventors: Jing Zhou, Zeshi Chu, Xu Dai, Yu Yu, Mengke Lan, Shangkun Guo, Jie Deng, Xiaoshuang Chen, Qingyuan Cai, Fangzhe Li, Zhaoyu Ji

Publication number: 20220085228Abstract: The present disclosure provides a two-dimensional material detector with an asymmetrically integrated optical microstrip antenna, structurally including a metal reflecting surface, a dielectric spacer layer, a two-dimensional active material layer, a top source electrode, and a drain electrode integrated with a metal strip array. Self-driven photoresponse of a metal/two-dimensional material/metal structure is induced by a Schottky junction formed due to contact between the two-dimensional material and the metal. The asymmetrically integrated optical microstrip antennas break the symmetry between the two contact/two-dimensional material junctions. Light absorption in the contact/two-dimensional material junction integrated with optical patch antennas is significantly enhanced by efficient light in-coupling and intensified light localization; meanwhile, the extended boundary of the contact/two-dimensional material junction enlarges the photocurrent collection area.Type: ApplicationFiled: September 15, 2021Publication date: March 17, 2022Applicant: Shanghai Institute of Technical Physics Chinese Academy of SciencesInventors: Jing Zhou, Shangkun Guo, Yu Yu, Zhaoyu Ji, Xu Dai, Jie Deng, Xiaoshuang Chen, Qingyuan Cai, Zeshi Chu, Fangzhe Li, Mengke Lan
