Abstract: A method and system utilizing both coordinate stroke data and associated pressure information for improved handwriting recognition. The method and system can also be applied to all types of handwriting-based data entry applications and also to user authentication. The digitizer pad used in the computer system gives both spatial information and associated pressure data when a stroke is being drawn thereon, e.g., by a stylus. Pressure information can be used to differentiate between different character sets and can also be used to adjust any display attribute, such as character font size, font selection, color, italic, bold, underline, shadow, language, etc.

Abstract: A handheld computer includes a processor; a memory in communication with the processor; and at least one light-emitting device that emits visible light as a visual indicator of an occurrence of a designated event. The processor is programmed to selectively activate the visual indicator in response to an occurrence of a designated event to provide the visual indicator to a user of the handheld computer. The processor is programmed to monitor for occurrence of two or more different types of designated events. The processor varies the visual indicator based on the type of the event for which occurrence is being signaled by that visual indicator, such that a different visual indicator is associated with each type of event for which the processor is programmed to monitor.

Abstract: A method and system utilizing both (x, y) coordinate (“spatial”) stroke data and associated pressure information for improved handwriting recognition. The method and system can also be applied to all types of handwriting-based data entry applications and also to user authentication. The digitizer pad used in the computer system gives both spatial information and associated pressure data when a stroke is being drawn thereon, e.g., by a stylus. Pressure information can be used to differentiate between different character sets, e.g., upper case and lower case characters for certain alphabetic characters. The spatial stroke data then identifies the particular character. The pressure information can also be used to adjust any display attribute, such as character font size, font selection, color, italic, bold, underline, shadow, language, etc. The associated pressure information can also be used for recognizing a signature. In this case, a user is allowed to sign a name on the digitizer pad.

Abstract: One embodiment in accordance with the present invention includes implementing a personal digital assistant (PDA) with a wireless personal identification mechanism. Specifically, the wireless identification mechanism can be a radio frequency identification (RFID) integrated circuit which is incorporated on the inside of the rear housing (e.g., plastic) of the personal digital assistant. Once the radio frequency identification integrated circuit has been implemented with an authorized security code, the personal digital assistant in accordance with the present embodiment is capable of functioning as a “key” enabling entry into restricted areas which are secured with non-contact radio frequency security systems such as corporate campuses, buildings, and/or laboratories. In this manner, an authorized person does not have to carry around a separate radio frequency keycard in order to gain access to restricted areas.

Abstract: An apparatus and method thereof wherein a portable computer system or personal digital assistant generates a visual signal in response to an occurrence of a programmed event. For example, the portable computer system can use a light emitting diode to visually signal an alarm at a specified time. The visual signal can be varied in order to indicate the type of event associated with the alarm. In one implementation, the visual signal blinks at a particular rate depending on the type of event. In another implementation, the visual signal blinks a prescribed number of times or according to a particular pattern depending on the type of event. When enabled, the visual signal is generated in lieu of an audible signal, thus providing to the user a silent alarm that does not disturb other people in proximity, such as in a meeting, a theater, or some other gathering.

Abstract: A method and system for enabling personal digital assistants (PDAs) and protecting stored private data. Specifically, one embodiment in accordance with the present invention includes a removable expansion card about the size of a postage stamp which plugs into a slot of a personal digital assistant. The removable expansion card, referred to as a personality card, is capable of storing all of a user's private information and data which is used within their personal digital assistant. By removing the personality card from the personal digital assistant, all of the user's private information and data may be removed from the personal digital assistant. Furthermore, the personal digital assistant may also be rendered totally or partially useless once the personality card is removed from it. There are several advantages associated with a personality card system in accordance with the present invention.

Abstract: A method and system for coupling to a palmtop computer that supports both mobile computing and desktop use. A palmtop computer docking system is disclosed that includes a cable assembly and a base. The cable assembly includes a palmtop computer connection mechanism that is connected to a USB connector and that is connected to a power connection mechanism via an electrical cable. Power is provided via the power connection mechanism. The cable assembly is adapted to engage the base so as to produce a fully functional docking cradle. In operation, once the cable assembly is engaged with the base, the USB connector is then coupled to the desired computing device (typically either a portable computer or a full-size computer). The resulting docking cradle facilitates desktop use such as, for example, communication with a full size computer. The cable assembly can be removed from the base and can be used independently of the base for mobile computing.

Abstract: A system and method that allows digital audio files, either streaming or stored to be controlled and selected and provides an analog audio signal for broadcast by a radio or amplifier without interfering with the operation of the host PC. A remote device is provided which facilitates control of the system.
