Publication number: 20220385730Abstract: The disclosed technology is directed towards a rules engine that determines whether a content asset such as a movie is allowed to be downloaded to a device, such as for offline viewing. A rules engine receives information of a request to download a content asset to a device, in which the request is associated with a user identifier and a content asset identifier. The rules engine obtains a rule identifier via the asset identifier, which is used to obtain a ruleset. The rules engine obtains user download state information associated with the user identifier, and evaluates the ruleset and the download state information to determine whether to allow the download of the content asset. A ruleset can include entries such as total downloads allowed, total downloads allowed by a studio that owns the content asset, downloaded copies of the same asset allowed (e.g., to different user devices), and the like.Type: ApplicationFiled: May 25, 2021Publication date: December 1, 2022Inventors: Zheng Hua, James Boisseranc

Patent number: 8721240Abstract: A cargo bracing device includes a fixing member and a driving member. Mainly the fixing member possesses a connecting plate easily fitted with one end of an elastic device, and a locking plate easily fitted with another end of the elastic device. So the locking plate can be restored with dynamic force provided by the elastic device deposited between the connecting plate and the locking plate. The driving member includes two wings respectively having one end formed as a hook collaborating with a latch of a driven plate to enable the driving member combined with or detached from the fixing member. Similar to the fixing member, an elastic device is easily installed between an actuating plate and a connecting bar of the driving member, providing dynamic force for restoring the actuating plate. Therefore the cargo bracing device can be easily assembled, even with automatic equipments.Type: GrantFiled: March 29, 2013Date of Patent: May 13, 2014Assignee: Lien Yang Industrial Co., Ltd.Inventors: Chun-Wei Wu, Chun-Yang Wu, Zheng-Hua Wu
