摘要:
A silicon MOSFET is provided, which can be made with an effective channel length of under one micrometer without incurring severe short-channel effects. The MOSFET includes first and second channel regions located between the source and drain regions, the first channel region overlaying the second channel region. The second channel region has a higher carrier density than the first channel region, and functions as a buried ground plane.

An automated message system sends a message of the calling party to the called party in response to a control signal. The automated message system includes a telephone network, a first telephone station, a second telephone station used by the called party and an automated message unit coupled to the first and second telephone stations through the network. A controller of the automated message unit that receives the control signal from the calling party selects a database from a memory device and retrieves a message from the database based on information included in the control signal. If an answering machine answers the calling party's call, the controller waits for the answering machine message to complete and sends the message retrieved from the database to the second telephone station of the called party.

A method and system for remotely controlling an interactive voice response (IVR) system. At least one command for controlling the IVR system is displayed using a graphical user interface based on locally stored information relating to a command menu for the IVR. When a command is selected from the display, a command sequence, that includes at least one DTMF tone, is generated that is related to each selected command. The command sequence also includes at least one DTMF tone that controls the IVR system to return to a higher level within the command menu when the command menu is hierarchical.

A system and method that identify the location of a wireless terminal. An illustrative embodiment of the present invention comprises a wireless communication system with a plurality of base stations. The system associates a location identification signal with each base station, such as an area code and an exchange of a telephone number in the geographic area of the base station. When a call is connected through a base station, the system modifies the caller-ID signal for the wireless terminal with the location identification signal of the base station. Thus, the system identifies the location of a wireless terminal.
