Abstract: A durable cover with a soft surface device (100) includes a substrate (10), an intermediate layer (20), an ink coating (30), and a top coating (40). The intermediate layer is made of a polyurethane paint. The ink coating contains a polyurethane component. The top coating is made of a polyurethane adhesive. The intermediate layer is applied onto the substrate, the ink coating is formed on the surface of the intermediate layer, and the top layer is formed on the surface of the ink coating and the intermediate layer. The presence of polyurethane in the intermediate layer, the ink coating, and the top coating promotes partial cross-linking therebetween and, thus, helps improve the durability of the cover. Further, the polyurethane contributes positively to the overall softness and flexibility of the cover.

Abstract: The present invention relates to an information card with multiple storage media. Combining reading and writing characteristics of magnetic strip storages, ICs, PFIDs, and etc. with large storage capacity of a compound printing 2D barcode, the invention uses a base card with a magnetic strip storage medium or a base card beset with an IC read-write chip, and a RF read-write chip. On said base card contains a first 2D barcode which has difference reflectivities to lights in the first spectrum area between bars and spaces, there is a designated relation between data stored in the magnetic strip or the IC chip, RF chip and data stored in the first 2D barcode. The invention discloses a read-write device of the information card comprising a Contact Image Sensor (CIS), a magnetic head or an IC chip reader, an RF chip reader. The invention further discloses a method for reading and writing data in said information card.

Abstract: An insert-type barcode reader has a body support with an insertion slot for receiving a card with barcode. A circuit board and a CIS component module electrically connected to the circuit board with each mounted to the body support to scan and process signals. A roller is mounted to the body support for movement relative to the CIS component module to allow the card to be properly guided into the insertion slot and tightly pressed onto the CIS component for accurate scanning of the barcode on the card. Two photoelectric sensors mounted to the body support are electrically connected to the circuit board for sensing the card entering and leaving the insertion slot to control starting, running and stopping of the scanning function of the CIS component module.

Abstract: A portable electronic device (100) includes a housing (10), a cover (20) and a latch (30). The housing has a latch receiving portion (150) defined at one end thereof The battery cover has a button hole (222) therein and includes at least one tab (224). The latch is fixed in the housing. The latch includes a button member (40) and an elastic member (50). The button member resists/biases the elastic member. The button member is received in the button hole of the battery cover and the latch receiving portion of the housing. The tab engages with the latch receiving portion. The elastic member has at least one clasp (56), which locks with a corresponding tab of the battery cover to the housing. When the elastic member is pressed by the button member, the clasp releases the tab. This release provides a user with convenient disassembly mechanism for the device.
