Bi-stable display technology and refresh display technology are integrated into a single device, which manages the use of these technologies to achieve power savings while providing a rich set of display functionalities that support interaction with content in a synergistic manner. Power saving functionality facilitates conservation of battery operating life, and flexible display functionalities enable access, display, and interaction with content in various ways.

Multi-display handheld device and supporting system

A device, such as an ADSL modem, acts as a proxy for service endpoints in a data network by responding to service endpoint advertisement messages pursuant to Point to Point Protocol (PPP) over Ethernet (PPPoE), where the terminating equipment located at those service endpoints do not support PPPoE services. The device also supports route selection and transparent protocol conversion of network protocols so that a host computer connected to the device can communicate with the service endpoints where the service endpoints do not support the host computer's network protocols (e.g., PPPoE). For example, the device converts PPPoE packets from the host computer to PPP packets and transmits and receives PPP packets with the service endpoint. The invention bridges a huge gap in the existing telecommunications infrastructure. The vast majority of the embedded base of product capable of acting as a service endpoint in the PPPoE protocol (such as the remote access server infrastructure providing dial-up Internet or corporate network access) does not presently support PPPoE protocol, whereas they do support PPP. By providing the proxy service in the device connecting the host computer to the service endpoint (such as a modem, e.g., ADSL modem), the host computer can obtain the benefits of PPPoE with virtually any potential device acting as a service endpoint, since the services provided by PPPoE are supported in the modem acting as a proxy for the service endpoint.
