Abstract: A system for licensing an application or feature for use on a wireless mobile device is disclosed. The wireless device is provided to a user with a licensable application or feature, but the application or feature has not been fully authorized for use. When the wireless device receives a request to use the application or feature, the device operates the requested application or feature, and generates an irrevocable license request. The license request is transmitted to a license server at a time convenient for the device. The license server generates a license certificate to the application or feature, and transmits the license certificate to the wireless mobile device. The device receives the license certificate, which is stored in local memory. The application or feature is now fully licensed for future operation on the wireless mobile device. The license server operates accounting processes to generate license reports and license accounting information.

Abstract: A camera module and a portable terminal comprising the camera module, in which an auto-focus (AF) function and a zoom function are assembled by using a friction drive-type drive source such as a piezoelectric element, which are constructed to be small in size and light in weight, and which are resistant to chips produced through friction contact between the piezoelectric element and driven member. The camera module has a lens holding section for holding at least one or more optical lenses and provided with a shaft hole portion, a shaft member inserted in the shaft hole portion and installed substantially in parallel with the optical axis, a piezoelectric element having at an end an operation portion that is in contact with the shaft member and is placed in the vicinity of the shaft hole portion of the lens holding section, and an adhesive member provided in the vicinity of the shaft hole portion.
