Publication number: 20230290077Abstract: A virtual window configuration method includes the following steps. A processor generates a virtual window. A depth detection sensor generates depth information based on an image. The processor analyzes the depth information to generate a depth matrix. The processor finds a depth configuration block in the image using the depth matrix. A feature point detection sensor generates feature point information for the image. The processor analyzes the feature point information to generate a feature point matrix. The processor finds a feature point configuration block in the image using the feature point matrix. The processor moves the virtual window to the depth configuration block or the feature point configuration block.Type: ApplicationFiled: September 13, 2022Publication date: September 14, 2023Inventors: Wei-Chou CHEN, Ming-Fong YEH, Yu-Chi CHANG, Lee-Chun KO

Patent number: 11294337Abstract: A power supply device which can be connected to an external device and flexibly distribute power is provided. A control circuit of the power supply device, when detecting that a shell connecting point of the power supply device is electrically connected to an external connecting point of a first external device, determines whether a type of the first external device is a load device and records device information related to the first external device in a power routing table. If yes, the control circuit transmits the power routing table to the first external device and then, instructs the power routing circuit to adjust a switch thereof according to a path table returned from the first external device so as to power the first external device. A power transferring device, a power supply method and a power transferring method are also provided.Type: GrantFiled: February 7, 2020Date of Patent: April 5, 2022Assignee: Wistron CorporationInventors: Wei-Lun Liu, Sheng-Hung Wang, Lee-Chun Ko

Patent number: 8461963Abstract: An access authorization method and apparatus for a wireless sensor network comprises at least a base station and a wireless sensor network formed by a plurality of sensor nodes. After having obtained an access authorization of a user, the at least a base station issues a request message to a target sensor node in the wireless sensor network. The target sensor node requests at least a controlling node in the wireless sensor network for sensing data sensed by the at least a controlling node, and checks if the sensing data meets the requirements of the access authorization of the user. Whether the target sensor node responds with the required multimedia or not is based on the checking result.Type: GrantFiled: January 6, 2010Date of Patent: June 11, 2013Assignees: Industrial Technology Research Institute, Carnegie Mellon UniversityInventors: Lee-Chun Ko, Virgil D.

Publication number: 20100146280Abstract: A remote assisting method is applied in a remote assisting system, which includes a server, a help-asking device and a helping device. The remote assisting method includes the following steps. First, ticket information is encrypted into encrypted ticket information, which is provided to the server, in response to a help-asking event and according to a first key. Next, the encrypted ticket information provided by the help-asking device is decoded into the ticket information according to a second key. Then, the ticket information, generated by decoding, is provided to the helping device such that the helping device can log in the help-asking device and perform a remote assisting operation.Type: ApplicationFiled: May 14, 2009Publication date: June 10, 2010Applicant: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Po-Yuan Teng, Lun-Chia Kuo, Yi-Hsiung Huang, Lee-Chun Ko
