The present disclosure provides a method for providing composite user interface controls and a library or online storefront for same. In one aspect, there is provided a method for a client computer of sharing a custom control, comprising: receiving by a browser an encrypted custom control comprising a number of user interface elements which are positioned in a specified manner with respect to each other, wherein each of the user interface elements has one or more properties; receiving by the browser a decryption key; and decrypting by the browser the encrypted custom control using the decryption key.

Method for providing composite user interface controls and an online storefront for same

Operation of a satellite-based navigation-signal broadcast system receiver, such as a GPS receiver, on a wireless communications device is controlled by determining whether the device is stationary or in motion. Motion determination is accomplished by analyzing radiofrequency signal traces, e.g. GSM signal traces, received from one or more nearby base stations. A three-tiered analysis provides a progressively more accurate determination as to whether the device is moving or stationary while providing, in certain instances, a more rapid determination than prior-art techniques. When the device is determined to be stationary, the GPS receiver can be deactivated. When the device is determined to be moving, the receiver can be reactivated.
