Abstract: A fully integrated email system for a desktop computer with an associated palmtop computer is disclosed. The portable computer has an email client for viewing incoming email messages and composing outgoing email messages. The personal computer has an email synchronization conduit that synchronizes email on the portable computer email client with email for the desktop computer system. The email synchronization conduit ensures that the email state on the portable computer system matches the email state on the desktop personal computer system exactly. Thus, if an email message is deleted on the portable computer system then that email message will be deleted from the desktop personal computer system. Similarly, if an email message is deleted on the desktop personal computer system then that email message will be deleted from the portable computer system.

Abstract: A handheld computer comprises a rechargeable battery module that outputs a source voltage to power one or more components of the handheld computer. The handheld computer includes a power monitoring module that receives the source voltage and outputs a rail voltage. The power monitoring module outputs the rail voltage to correspond to a fractional duty cycle of the source voltage when the source voltage is greater than a designated voltage. The power monitoring module outputs the rail voltage to correspond to a full duty cycle of the source voltage when the source voltage is less than the designated voltage. The handheld computer includes a power rail coupled to the power monitoring module. The power rail receives the rail voltage so as to extend power from the battery module to the one or more components of the handheld computer.

Abstract: A plurality of sound-detecting devices are configured to detect sound from an event of interest. Information about the sound is recorded that is dependent on a distance between the source position and the location of the sound-detection devices. The source position is approximated using the recorded information and the relative position of individual sound-detection devices to one another. The approximated source position is used as input for operating a electronic device.

Abstract: An embodiment includes a power management method for regulating power to a handheld computer. A source voltage is received from a battery module. The source voltage is regulated to power a plurality of internal components, including a processor and a memory. If the source voltage is detected to be less than a designated threshold, the plurality of internal components powered by the source voltage are reduced to allow a charge of the battery module to increase in absence of an external charge.

Abstract: Embodiments of this invention provide for a portable computer that determines whether an accessory device is actively connected to it. In one embodiment, the portable computer may include a signal line accessible through an output of the portable computing device. The signal line may be connected to a communication device such as a communication cradle. The portable computer may detect a signal on the signal line to determine whether the communication device is actively connected to the portable computer. If the communication device is actively connected, the portable computer suspends implementation of a time-out feature that would otherwise reduce power consumption of the portable computer.

Abstract: Data communications are provided in a computer system by accepting message information within a unified information exchange manager. The unified exchange manager is executed to select an appropriate application from a plurality of applications that are executable on the computer system. The unified exchange manager selects the appropriate application based on a data type of the message information. The message information from the unified information exchange manager is passed to the appropriate application program if said user accepts said message information.

Abstract: A communications device provides a user with a sensory cue that informs the user of certain characteristics of a subsequent action that includes data communications. By informing the user of the data communication characteristics before the user initiates the data communication action, the invention appropriately sets user expectations regarding the data communication characteristics. For example, one embodiment of the invention is implemented in a portable communications device with a screen. For subsequent actions that include wireless communications, the portable communications device simultaneously displays a wireless link icon sensory cue next to a user interface graphic element. The user interface element is used to initiate the subsequent action. The user interface element can be an operating system object having an embedded link type icon.

Abstract: A housing component is provided for a handheld computer. A film layer corresponds to an exterior surface of the housing component. The film layer may have a first tone and a second tone. A groove is formed on the film layer. The groove has a contoured interior. The first surface on the interior of the groove may have the first tone. A second surface on the interior of the groove may have the second tone.

Abstract: Methods and apparatus are provided for reserving power in a handheld computer by inducing a sleep mode when the energy supply of the handheld computer reaches a predetermined low level. A software is provided which operates a sleep mode when a device of the handheld computer detects a predetermined low battery voltage. A processor operates the software to place the handheld computer in a low energy-consuming shutdown state in which an interrupt controller operates to mask those interrupt signals thus providing an user with the impression that the device has entered an unresponsive sleep mode. In maintaining the sleep mode, the processor operates such that all input signals that request the handheld computer to power up remain active but so long as the battery voltage remains below a predetermined voltage the interrupt signals to power up selected applications and devices are masked.

Abstract: To efficiently recognize characters from several character sets, a palmtop computer system is disclosed wherein more that one character input area is displayed. Each character input area is designed to recognize strokes that represent characters from a different character set. In one embodiment, the palmtop computer system has an alphabetic input area and a numeral input area. In such an embodiment, strokes entered in the alphabetic input area are interpreted as alphabetic characters and strokes entered in the numeral input area are interpreted as numerals.

Abstract: A connector assembly is provided for use with a handheld computing system. The connector assembly includes a first connector including a plurality of contact elements. A second connector resides on a cradle and includes a plurality of contact elements that mate with the contact elements on the handheld computer. A coupling structure is configured to extend from the cradle and to couple to the handheld computer. The coupling structure causes a portion of the handheld computer to bias into the cradle so as to direct the first connector to remain in contact with the second connector.

Abstract: A handheld computer includes a bar retained in an interior. A first button structure is accessible on an exterior surface of the handheld computer. A member joins to and extends between the bar and the first button structure. The member enables the first button structure to move into an actuated position without undergoing a radial motion about the bar.

Abstract: A door mechanism is provided for a handheld computer. The door mechanism includes a detachable section that is extendable from an interior of the handheld computer's housing. The detachable section is biased to pivot towards the housing from the extended position. An interior of the detachable section includes a coupling structure to receive an external electrical component. The detachable section may be returned to a closed position to cause the external electrical component to make contact with an interior element of the handheld computer.

Abstract: An accessory device for a handheld computer includes a peripheral portion to detachably couple to an accessory rail of a handheld computer. The accessory device includes a cover portion dimensioned to extend over a front surface of the handheld computer including a display when the peripheral portion is coupled to the accessory rail.
