  • Patent number: 12209436
    Abstract: A cross bar type unlock-driving structure, to be mounted in a panel-outside space of a door panel, includes a handle-end frame, a mounting frame, a handle and a driving member, and a handle seat. The handle-end base includes a basic frame and a mounting frame to form an accommodation space with both vertical and horizontal opening. The handle and the driving member, integrated as a unique piece, provide the driving member to be formed as an extension finger for pushing an unlock-driven unit disposed inside the accommodation space. The handle seat, mounted onto the middle plate of the mounting frame, is to mount pivotally the handle and the driving member with the driving member located in the accommodation space and the handle located out of the handle seat. With the vertical and horizontal opening provided to the accommodation space, different types of lock cartridges can be contained.

  • Patent number: 10597910
    Abstract: A universal door lock-driving assembly is installed in an exterior space of a door panel. The door panel is furnished with at least one of an embedded lock cartridge, an embedded vertical-extending lock bar assembly and an exposed vertical-extending lock bar assembly. The universal door lock-driving assembly includes a base set, an action unit, a driving member and a slidable unit. The slidable unit can assemble a first assembling member and a second assembling member. The first assembling member can apply a penetration slot on the base set to generate interaction with the embedded lock cartridge or the embedded vertical-extending lock bar assembly. The second assembling member can interact with an exposed lock bar. Thus, the universal door lock-driving assembly can be used to unlock at least the lock cartridge and the lock bar assembly.

  • Publication number: 20160168879
    Abstract: A locker assembly is mounted outside to a door board having a penetration hole for cooperating with one of an embedded lock casing, an embedded vertical extended-rod locking assembly and an exposed vertical extended-rod locking assembly mounted on the door board. The locker assembly includes a base, a sliding unit, a fixation base structure, a toggle coupled with the fixation base structure and a rocker arm. The base has a through aperture and applies the sliding unit to adopt commonly the locker assembly. The sliding unit can assemble a turning application rod penetrating both the through aperture and the penetration hole. While the rocker arm is depressed, the toggle rotates to slide the sliding unit and so as further to drive the turning application rod inside the through aperture and the penetration hole to further perform the unlocking of the door board.

  • Patent number: 9325351
    Abstract: A turbo decoder includes a plurality of decoder cores arranged for parallel decoding of a plurality of code segments of a code block in an iteration. Each of the decoder cores is arranged to decode a corresponding code segment according to a sliding window having a window size smaller than a length of the corresponding code segment in most cases, and sequentially generate a plurality of decoded soft outputs each derived from decoding an encoded soft input selected from the corresponding code segment by the sliding window.

  • Patent number: 9026883
    Abstract: A decoding apparatus has an on-chip buffer, an external buffer interface, and a turbo decoder. The on-chip buffer is arranged for buffering each code block to be decoded. The external buffer interface is arranged for accessing an off-chip buffer. The turbo decoder is arranged for decoding a specific code block read from the on-chip buffer. The specific code block is not transmitted from the on-chip buffer to the off-chip buffer via the external buffer interface unless decoding fail of the specific code block is identified.

  • Patent number: 8091097
    Abstract: A distributed virtual machine architecture includes a virtual machine client (16) and a virtual machine server (32). The virtual machine client provides a platform upon which an application may be run on a host device (12). The virtual machine server may appear anywhere within the network to which the host of the virtual machine client is connected (14). When the application request a class, the virtual machine client determines such class exists on the local host (12) or a client proxy exist for the class. If neither exists, the virtual machine client connects to the virtual machine server to send a request for the class. If a proxy does exist, a proxy is returned to the virtual machine client. However, if a proxy does not exist, the virtual machine server dynamically generates the proxy (34) to be returned to the virtual machine client.

  • Publication number: 20050220942
    Abstract: The present invention teaches a film having a pealably sealable layer. When used in the vacuum packaging bag material context, the result is a vacuum packaging bag that a consumer can evacuate and hermetically seal. The consumer may later open the bag through a manual pealing action that does not require a tool and that does not result in wasting or destroying a portion of the vacuum packaging bag. The present invention also contemplates a variety of applications for the pealably sealable films, including preformed bags and bag rolls, as well as a variety of apparatus for manufacturing the films and appliances for utilizing the bags and bag rolls.

  • Patent number: 6559049
    Abstract: The present invention reveals a semiconductor dual damascene etching process, which uses a confined plasma etching chamber to integrate all dual damascene steps such as via hole etching, photoresist stripping and barrier layer removal which originally performed in various reactors as a continuous procedure in the confined plasma chamber. The confined plasma chamber including a confinement ring surrounding a wafer and an anti-etching upper electrode plate performs the steps mentioned above under clean mode. The present invention can not only reduce the time period required by the semiconductor dual damascene process but also greatly reduce the manufacturing cost.
