Abstract: PROBLEM TO BE SOLVED: To provide a VoIP(Voice over Internet Protocol) based voice system where the design and installation of voice applications maintain a state separated from the design and installation of IP telephony systems. SOLUTION: A VoIP compatible voice server includes a voice application that can be configured to make communication with a VoIP telephony gateway server via a VoIP communication path. Furthermore, the VoIP compatible voice server includes a VoIP compatible call control interface leading to the VoIP telephony gateway server and the VoIP compatible call control interface builds up the VoIP communication path. In an operation, the voice application receives a VoIP compatible packet via the VoIP communication path. As a result, digitized voice data can be reconfigured with the VoIP compatible packet. The digitized voice data are converted into a voice-text. Furthermore, the text is synthesized with the digitized voice data, and the digitized voice data is capsulated into the VoIP compatible packet, which is transmitted to the telephony gateway server via the VoIP communication path.

Abstract: A digitizer tablet computer has a host processor connected to a service processor which, in turn, is connected to a digitizer controller and to a power subsystem microcontroller. A battery supplies the primary power for operating the computer but the computer is also connectable to an external source of DC power to charge the battery and to operate the computer when it is not running on battery power. The service processor includes a battery gauge the contents of which indicate how much power is left in the battery and how much time remains at the current rate of power consumption before the power runs out. The amount of remaining power in the gauge is determined by keeping track of power consumed, power added, and power lost during off periods. The use of the second derivative of a voltage versus time discharge curve creates a point from which relative accurate estimates can be made of how much longer the computer can be operated.

Abstract: The present invention provides a system and method for managing power in a portable, pen-based notebook computer. The system and method provides a means for minimizing power consumption by collecting and interpreting power related data at various processing elements while hiding many of the details from the end-user. The present invention is a system and method for monitoring, collecting and acting upon power-related data in portable computer to maximize the amount of time the portable computer can be used between battery re-charging with minimal user intervention. The present invention is comprised of a plurality of independently controllable power planes which are selectively powered so that the portable computer consumes the minimum power necessary to perform a particular function and a plurality of central processing units (CPUs) operating asynchronously with respect to each other. The present invention is further comprised of an on/off glue logic means for monitoring battery condition, user invoked functions, and system state and a power management means for controlling the operation of each of the CPUs as a function of the conditions sensed by the sensing means.

Abstract: A digitizer tablet computer has a host processor connected to a service processor which, in turn, is connected to a digitizer controller and to a power subsystem microcontroller whereby primary control of a keyboard, a digitizer, and a power subsystem is off loaded from the host processor to the service processor. The host processor communicates with the service processor through an interface comprising a status register, an input buffer and an output buffer through which host commands and data are transferred. The digitizer produces coordinate data that is initially processed in the service processor before being passed on to the host processor. The host processor is interrupted to receive the processed data and executes in a tight loop until a predetermined amount of processed data is received.
