  • Publication number: 20040125553
    Abstract: A wireless network adapter for establishing wireless communication links between electronic devices. In one embodiment, the wireless network adapter comprises wireless communication circuitry encased in a shell in the form of a detachable molding element of an electronic device. The wireless network adapter further comprises a bus connector adapted to couple the wireless communication circuitry to an expansion bus when the shell is attached to an outer surface of an electronic device. The wireless network adapter is a fully integrated solution further comprising an RF antenna for communication with a wireless network and a radio modem comprising a radio, a receiver, and modulation circuitry. The RF antenna in the wireless network adapter may take one of several forms. The antenna may be a dedicated unit housed within the shell of the wireless network adapter. Alternatively, the antenna may form a part of the outer shell of the adapter or it may form a part of a company logo located on the shell the adapter.

  • Publication number: 20030125070
    Abstract: An electronic device has a display in which the casing of the display includes a plurality of recessed cavities into which radio and antenna modules can be inserted to provide the electronic device with a wireless communication capability. The display can have cavities for one or more radios and one or more antenna modules. A radio electrically connects to one or more antenna modules via conductor(s) contained within the display and connects to the host electronic device via a serial bus (e.g., USB). Accordingly, the display can have a plurality of radio/antenna combinations thereby concurrently providing the electronic device with multiple wireless communication capabilities.

  • Publication number: 20020058533
    Abstract: A modem is incorporated into a laptop computer and directly connected to either a cellular phone, a land line, or both. The modem is provided with two connectors, one for connection with a cellular phone or external DAA, the other for connection to a normal land line via an internal DAA. The modem selectively enables either the connector for the cellular phone or external DAA, or the connector for its internal DAA. The modem defaults to selecting the cellular phone or external DAA if it is connected, and only if they are not connected selects the internal DAA. These defaults can be overridden by user commands. Further, the modem can independently power down a connected internal DAA, external DAA, or cellular phone to conserve power.

  • Patent number: 5964850
    Abstract: A method and apparatus for increasing system functionality through a predefined interface is disclosed. Signal lines which are not used or which are not used in certain modes are connected to an interconnection device instead of being connected to an interface wherein the output of the interconnection device is connected to the interface where such lines would have been connected. The interconnection device also has a set of inputs for receiving signals from a device providing the desired functionality. A controller chooses between the two sets of inputs to control what signal lines are connected to the predefined interface. Accordingly, during certain modes of operation, the added functionality from a device whose output is being switched into the interface can be supported. In one embodiment, speaker phone capability is provided for even though the predefined PCMCIA interface does not support such capability.

  • Patent number: 5931929
    Abstract: A laptop computer contains a built-in modem and has a phone jack for connection to a telephone line while the computer is being operated in a stand-alone mode. A docking station into which the laptop computer may be docked allows the combined unit to be operated in a desk-top mode. The docking station may have a full-sized keyboard and display so that the laptop functions as the main computer a user may employ in the office or home. A telephone connection is already in place at the docking station so that the user need not make a phone line connection to invoke the docked mode, but instead merely nests the laptop in the docking station.

  • Patent number: 5428671
    Abstract: A modem which includes connections for both land lines and a cellular phone. The modem contains high and low level routines that allow it to perform standard AT commands rationally when connected to a cellular phone, and further perform additional AT commands that access cellular specific features. An applications software program in a computer connected to the modem can provide a number of options for determining whether to use the land line or the cellular phone when both are connected. First, it can default to the land line and only use the cellular phone if the land line is not available. Alternatively, it can first use the cellular phone and only use the land line if the cellular phone signal strength is not sufficient. Further, cellular file transfer operations can be aborted if the remaining battery life in the cellular phone is insufficient to reliably complete the transfer.
