A computer system which includes one or more wireless interface devices that are adapted to communicate with a remote host over a radio link. Each of the wireless interface devices is a pen-based device which includes an ink field in which pen events are translated into pen data packets and transmitted to the remote host over the radio link. Local inking is provided at the wireless interface device in order to maintain the pen paradigm in essentially real time.

Wireless File Transmission

A pen-based portable computer system, and more particularly, to a computer system which includes a host computer or a server that is adapted to interface with one or more wireless interface devices over a radio link. The wireless interface devices are pen-based devices which include a digitizer panel and are adapted to operate on a mouse mode, as well as a pen mode. In a mouse mode, pen down events are translated into mouse data and transmitted over the radio link to the remote server or host computer. In a pen mode, pen down events in an ink field are formulated as pen data. In accordance with an important aspect of the present invention, the wireless interface device includes a local handwriting recognition system for translating handwriting into characters which are then transmitted to the remote server or host computer over a radio link for processing.

Local handwriting recognition in a wireless interface tablet device

A system which includes a personal computer or a server adapted to be connected by way of a radio link to one or more wireless interface devices. Each of the wireless interface devices is configured to support multimedia applications and may include a speaker, as well as a microphone, for audio input. Audio input data is compressed and transmitted over a radio link to a remote computer or server.

Audio compression in a wireless remote interface tablet

A pen-based portable computer system which includes one or more pen-based wireless interface devices that are adapted to communicate by way of a radio link to a remote host personal computer or server. The pen-based wireless interface device is adapted to operate in a pen mode and a mouse mode. In a mouse mode, pen down events are translated to mouse data and formulated into mouse data packets which, in turn, are transmitted over the radio link to the remote host computer or server. In order to enable the wireless interface device to switch to a pen mode, one or more ink field is created within a container application. On power-up, the system comes up in a mouse mode. Pen events within the ink field cause the system to transfer to a pen mode. Pen events within the container application are translated into pen data packets transmitted over the radio link to the remote host computer or server.

Mode switching for pen-based computer systems

A computer system which includes one or more wireless interface devices that are adapted to communicate with a remote host over a radio link. Each of the wireless interface devices is a pen-based device which includes an ink field in which pen events are translated into pen data. packets and transmitted to the remote host over the radio link. Local inking is provided at the wireless interface device in order to maintain the pen paradigm in essentially real time.

A wireless interface device for interfacing with a host computer connected in either a wired or wireless local area network (LAN). The wireless interface device includes a display that mirrors whatever is being displayed on the host computer to which it is connected. In order to reduce unnecessary LAN traffic, any screen savers running on the host computer are automatically disabled when a radio connection is made between the host computer and the wireless interface device. When the wireless interface device is disconnected from the host computer, the screen saver running on the host computer is automatically re-enabled.

Screen saver disabler

A plurality of wireless interface devices, interfaced to a server that may be connected in either a wireless or wired LAN. Each wireless interface device may be a pen-based device which communicates with the server over a radio link. An alternative input system is provided on the wireless interface device in the form of a virtual on-screen keyboard (OSK). Once radio communication is established between the wireless interface device and the server and the OSK is launched, the system prevents overriding of the OSK on the display of the wireless interface device.

Multi-user on-screen keyboard

A system which includes a plurality of wireless interface devices, adapted to be interfaced with a server, connected in either a wireless or wired LAN. Prior to an interface being established, the wireless interface device broadcasts for available servers which, upon acknowledgment are displayed in a dialog box on the display of the wireless interface device. The user selects an available server from the dialog box for connection to the wireless interface device.

Wireless enumeration

A system which enables a plurality of wireless interface devices to be connected by way of a radio link to a server in either a wired or wireless LAN. On power-up for the wireless interface device, the wireless interface device upon initiation broadcasts for available servers available for connection. The system automatically determines the server with the least amount of load and displays that server on a dialog box on the display of the wireless interface device. The user is then able to select that server from the dialog box.

Dynamic server allocation for load balancing wireless remote interface processing

A system in which a plurality of wireless interface devices, each containing one or more flash memory devices, are interfaced to a server which may be connected in either a wireless or wired LAN by way of a radio link. The system in accordance with the present invention, enables the flash or other type of memory devices in the plurality of wireless interface devices interfaced to the server to be updated over a radio link.

Multi-user flash ROM update

A pen-based portable personal computer can emulate the functions of a standard two-button mouse. In particular the system can emulate standard movement and clicking of a mouse buttons as well as emulate both left and right mouse buttons of a two-button mouse. In order to be compatible with various application programs, the system can also emulate the double clicking of the mouse button. By providing a pen-based computer system which can emulate the functions of a standard two-button mouse, the system is compatible with various application programs available on the market

Mouse emulation with a passive pen

Briefly, the present invention relates to a wireless interface device that can be interfaced to a wired local are a network (LAN) by way of a multiplexer which manipulates the source and destination addresses of the packets in order to be compatible with a standard protocol, such as IPXODI, which normally only supports a single LAN card.

System and method for enabling an IPX driver to accommodate multiple LAN

A wireless interface device is adapted to be interfaced with a host computer. Prior to an interface being established, the wireless interface device broadcasts for available hosts, which, upon acknowledgement, appear in a dialog box on the display of the wireless interface device. The user is then able to select an available host from the dialog box.

Broadcast search for available host

A wireless interface device is adapted to be interfaced with a host computer by way of a radio link. A wireless interface device includes one or more flash memory devices that are adapted to be updated by the host computer over the radio link.
