Publication number: 20250231219Abstract: A testing method for a micro-bump test includes providing a device under test arranged with a first bump unit for transmitting the power or ground signal and a second bump unit for transmitting the test signal, the first and second bump units both having grouping micro-bumps, or one of them only having a single relatively larger bump, the micro-bumps of the second bump unit including a selected micro-bump and a dummy micro-bump; providing a test apparatus including a chuck and a probe card whose probes' body portions are substantially the same in size; placing the device under test on the chuck, and testing it by the probes. The probe card is lowered in manufacturing difficulty, cost and difficulty in usage on a testing machine, and prevented from different probe wear loss and the resulting poor probe planarity problem. The device under test is prevented from too complicated design.Type: ApplicationFiled: January 14, 2025Publication date: July 17, 2025Applicant: MPI CORPORATIONInventors: CHIN-TIEN YANG, TSUNG-YI CHEN, HUI-PIN YANG

Patent number: 11832199Abstract: A method is provided for synchronizing timing in phase and frequency of clocks associated with a plurality of radio nodes (RNs) in a small cell radio access network (RAN) having an access controller operatively coupled to each of the RNs. In accordance with the method, a donor list is generated for each given RN in the RAN. The donor list represents an ordered list of potential wireless access points that are able to serve as a source of a wireless sync signal for the given RN. The donor lists are distributed to the respective RNs. An access point is selected by each of the RNs from their respective donor lists to use as a sync signal source. Each of the RNs synchronize their respective clocks in phase and frequency using wireless sync signals received from the respective selected access points.Type: GrantFiled: January 12, 2023Date of Patent: November 28, 2023Assignee: CORNING OPTICAL COMMUNICATIONS LLCInventors: Tsung-Yi Chen, Olivier Duval, Hithesh Nama

Patent number: 10785800Abstract: Systems and methods for dynamically selecting energy detection thresholds (EDTs) in radio nodes deploying listen before talk within a coordinated network to improve throughput on shared spectrum are disclosed. The radio nodes are configured to coordinate to deploy mechanisms to avoid or reduce interference issues, including collisions, with use of shared spectrum (e.g., unlicensed spectrum). One such mechanism is Listen Before Talk (LBT), and a radio node deploying LBT sets an EDT at which the radio node hears traffic from neighboring radio nodes on the shared spectrum. In an exemplary aspect, the EDT of radio nodes in the coordinated network of radio nodes can be dynamically selected and/or adjusted to improve throughput of the individual radio nodes and/or of the network of radio nodes as a whole.Type: GrantFiled: November 27, 2018Date of Patent: September 22, 2020Assignee: Corning Optical Communications LLCInventors: Tsung-Yi Chen, Hithesh Nama, Jiadong Wang

Patent number: 10764927Abstract: Systems and methods for dynamically selecting and adjusting energy detection thresholds (EDTs) in uncoordinated radio nodes deploying Listen Before Talk to improve throughput on shared spectrum are disclosed. The uncoordinated radio nodes dynamically adjust an EDT to avoid harmful collisions with neighboring radio nodes or otherwise improve throughput over shared spectrum. A radio node can detect a collision or radio frequency (RF) interference from a neighboring radio node. Once the collision or RF interference is detected, the EDT of the radio node is dynamically adjusted. In some cases, the collision or RF interference can be avoided by calculating a throughput of the radio node while operating on each of a plurality of EDTs and selecting the EDT predicted to result in a higher throughput. In other cases, the EDT may be dynamically adjusted based on an iterative approach which incorporates measurements of the neighboring radio node.Type: GrantFiled: November 28, 2018Date of Patent: September 1, 2020Assignee: CORNING OPTICAL COMMUNICATIONS LLCInventors: Tsung-Yi Chen, Hithesh Nama, Jiadong Wang

Patent number: 10645666Abstract: Systems and methods disclosed detect significant changes in the RN topology after an E-RAN system has been installed and provisioned. If a significant change is detected, the operator is notified through an alarm, and the operator can take action to correct it. For example, an RN whose location was moved may be disabled. Alternatively, the movement operation may be approved and the alarm cleared so long as the operation falls within certain approved guidelines or categories, e.g., is appropriately reported and a new location noted.Type: GrantFiled: March 28, 2017Date of Patent: May 5, 2020Assignee: Corning Optical Communications LLCInventors: Ruibin Song, Tsung-Yi Chen, Olivier Duval, Paresh Bhaya
