Abstract: A system, method and apparatus of mobile account access through a data processing system are disclosed. In one embodiment, a system includes a personal computer coupled to a network, a mobile service provider module of a mobile network to provide access to a mobile account, to verify that the mobile account is authorized by a mobile service provider, and to enable usages of services associated with the mobile account; and a virtual cell module of the personal computer to communicate an identification data of the mobile account to the mobile service provider module to be verified and to provide access to the mobile account through the personal computer. The system may also include a purchasing module of the virtual cell module to request and to download multimedia data from a content provider coupled to the mobile service provider module to display on the virtual cell module.

Abstract: In the present invention, when one open or running software application having secured features enters an access signed-in or logged-in state, other open or running software applications having secured features enter a ready signed-in state automatically, without prompting user intervention. The same operation that signed-in or logged-in the initial software application will transition other software applications that are presently open, active to run, or that start in run mode to a ready signed-in state. The access signed-in state fully authenticates the user's identity and grants access to secured features. The ready signed-in state places the software application in a state of readiness to authenticate and access secured features without prompting user intervention. One feature of the present invention is the sharing of a sign-in or login credential (e.g.

Abstract: The present invention automatically signs or logs a user in to access secured features within a software application without prompting manual intervention when a user starts the software application having secured features. When the software application is started and an automatic sign-in condition is enabled, the software application transitions to a signed-in or logged-in state as long as security criteria are met. As a result, unnecessary and repetitive steps are avoided when signing-in. The automatic sign-in condition may be enabled through initial system setup, from a prompt to enter a credential, or through a service options menu. The present invention improves network efficiency by limiting network transmissions to an as needed basis. The automatic sign-in condition is capable of roaming to other computers within a network, thereby following mobile users.

Abstract: A control circuit for a piezo transformer based power supply includes oscillator circuitry, drive circuitry, sense circuitry, and feedback circuitry collectively operating to regulate an operational parameter of the supply, such as the current supplied to a cold cathode fluorescent lamp (CCFL). The feedback circuitry includes initialization circuitry that establishes an initial value of an oscillator control signal corresponding to an initial operating frequency, and thereafter permits the feedback circuitry to gradually drive the oscillator control signal to a normal operating value such that the operating frequency is swept from the initial operating frequency to a normal operating frequency. When controlling the power supplied to a CCFL, the initial operating frequency is preferably a maximum frequency of the oscillator, and the operating frequency is swept downward so as to pass through the frequency at which the lamp “strikes”, or begins conduction, and thereafter into regulation.
