A cloud door lock control system identifies time varied 2D codes and images. A cloud device transmits the encryption codes of doors to be opened, the time periods for opening the doors, and the user's encryption codes to the mobile phone. The mobile phone stores these values in a memory. A mobile phone APP receives these values and encrypts them by using a specific encrypting code. The encoding way for the encoding unit is time varied. When the cloud device receives the QR code from a card reader, it is decoded and is compared with those stored in the cloud device to determine whether the door is necessary to be opened. The cloud device stores mobile phone holder's images which is transferred to the APP. The mobile phone holder's image is displayable on the mobile phone for determining whether the mobile phone holder is acceptable to pass through the door.

Cloud door lock control system with identification of time varied 2D codes and images

A cloud door lock control system with identification of time varied 2D codes is provided. A cloud device transmits the encryption codes of doors to be opened, the time periods for opening the doors, and the user's encryption codes to the handset through a communication channel and the handset stores these values in a memory. A mobile phone APP receives these values and encrypts them by using a specific encrypting code. The encoding way for the encoding unit is time varied, that is, the QR code from the encoding unit is only retained for a preset time period; after the preset time period has elapsed, the encoding unit generates another QR code. When the cloud device receives the QR code from a card reader, it is decoded. These decoded data is compared with those stored in the cloud device to determine whether the door is necessary to be opened.

A bonding apparatus includes a bond head structure, an optical unit and an actuator unit. The bond head structure includes a bond head collet, a connecting unit to which the bond head collet is attached and a look-through passage extending through the bond head collet and the connecting unit along a central axis of the bond head structure. In use, the bond head collet holds an electrical component to be bonded to a bonding area of a base member and the optical unit is positioned relative to the bond head structure to view and inspect the electrical component through the look-through passage of the bond head structure. The actuator unit moves the connecting unit of the bond head structure based on the inspection of the electrical component by the optical unit, to align the electrical component with the bonding area of the base member.

High precision bonding apparatus comprising heater

A bonding apparatus includes a holding element, holding element actuators, sensors, a controller and bond force adjusting actuators. In use, the holding element holds an electrical component and is moved by the holding element actuators in one or more actuating directions to contact the electrical component with a base member. The sensors measure reaction forces exerted on the holding element in response to contact between the electrical component and the base member. The controller determines bond forces to be exerted on actuating areas of the holding element during a bonding process based on the measured reaction forces, and the bond force adjusting actuators exert these bond forces on the actuating areas of the holding element during the bonding process, so as to adjust a tilt of the electrical component relative to the base member.

Methods and systems for encoding and decoding a 2D symbol is disclosed. According to one aspect of the 2D symbol, the following characteristics are realized: 1) variable symbol widths and height; 2) variable print resolution, 3) multiple damage protection levels; 4) large information storage; 5) high redundancy; 6) readable by line based scanning devices; 7) recognizable by either contact scanning or non-contact scanning devices. In addition, a set of positioning lines are attached 2D symbol for guiding scanning devices to decode the 2D symbol with proper resolution.

Methods and systems for encoding and decoding data in 2D symbology

To facilitate the decoding of a 2D symbol (e.g., PDF417), a plurality of positioning lines are attached to the 2D symbol. Depending on implementation, these substantially parallel positioning lines may be provided on at least one side of the symbol or superimposed on the symbol. A scanning device is provided to capture an image of the symbol together with these positioning lines that are then detected to determine an orientation of the 2D symbol. In some cases, these positioning lines are used to correct images with distortion.
