Abstract: In one implementation, an antenna array has a plurality of antenna element, each of which is configured to apply a phase shift to a signal. A beam steering controller is configured to steer a main beam of the antenna by controlling the phase shifts applied by the antenna elements. In addition, the beam steering controller also is configured to detect a failure of an antenna element and, in response to detecting the failure, disable the failed antenna element and modify the phase shifts applied by remaining ones of the antenna elements.

Abstract: A method and apparatus for user input on a handheld device with a virtual keyboard using secondary surfaces. On the primary surface of the device (e.g., front), the user interacts via touch sensors and a display element. Secondary surfaces (e.g., back) include additional touch sensors through which the user can also provide input. The display element is used to present information appropriate to the device's function (e.g., email messages) and control elements, including a virtual keyboard. The user interacts with the touch sensors on the first surface to bring up the virtual keyboard. Once displayed, the user can interact with this keyboard using either the primary surface or secondary surfaces. When used on appropriately sized device, the user can hold the device with the palms and thumbs of both hands and use their fingers on the touch sensors on the secondary surfaces to type.

Abstract: A method and system use voiceband transmission characteristics to estimate the viability of deploying broadband services over a subscriber loop in the public switched telephone network. The system gives network service providers the ability to predict the performance of broadband transmission channels, such as ADSL, on a subscriber loop from a central location and without reliance on outdated loop records maintained by a carrier. Based on this predicted performance a network service provider is able to efficiently determine the viability of deploying ADSL to a subscriber and, in turn, determine the viability of deploying ADSL in entire areas by creating an ADSL--ready consumer-lead list. The method comprises establishing an end to end voiceband modem connection from a logic device to a remote computer over a facility wherein the only analog elements reside in the subscriber loop.
