Abstract: Method and arrangement that provides a power-saving mode for a handheld electronic device. The power-saving mode is enabled through disabling a sensor that detects motion of a ball of the trackball navigation tool and disabling the display screen of the handheld electronic device. The power-saving mode may be exited before disablement of the sensor when the display screen is disabled first.

Abstract: System and method that provides audible feedback through a speaker of a handheld electronic device having a reduced alphabetic keyboard upon actuation of a navigation tool. The audible feedback produced by the speaker is capable of being modified based upon the location, speed, and other characteristics of the movement of a cursor on the display of a handheld electronic device. The sound produced by the speaker can originate from an audio file stored or otherwise available on the handheld electronic device.

Abstract: Method and arrangement for adjusting sensitivity in the horizontal and/or vertical directions for the motion of a cursor on the display of a handheld electronic device incorporating a trackball as a user input device. The sensitivity can be user defined, program defined or a combination of the two. The sensitivity adjustment allows for special properties associated with the device's display dimensions and navigation device.

Abstract: Method an arrangement for affecting diagonal movement of a cursor 171 on the display screen 322 of a handheld communication device 300 having a full alphabetic keyboard. The method includes sensing movement at an auxiliary user input 328 of the handheld communication device 300 indicative of the user's desire to affect diagonal movement of the cursor 171 on the display screen 322 of the handheld communication device 300. X-direction signals and Y-direction signals are produced based on the sensed movement at the auxiliary user input 328. During that time while the necessary signals are being collected and processed, the cursor 171 is held steady on the display screen 322 until a predetermined criterion is met for discriminating whether the user has indicated x-direction cursor movement, y-direction cursor movement or diagonal cursor movement.

The smart battery includes a battery processor for controlling the operation of the smart battery and communicating with the main processor; and a battery memory coupled to the battery processor for storing a Battery ID indicating the model of the smart battery. The main processor is configured to communicate with the battery processor to obtain the Battery ID and select one the battery information profiles based on the Battery ID.

Abstract: The invention provides a system and method for activating an electronic device from a low power state. In the system, an activation circuit for an electronic device is provided. The circuit comprises: a motion sensor circuit; an input device; and a monitoring circuit connected to the input device. The monitoring circuit provides power to the input device when the motion sensor circuit detects a notable movement of the device and selectively generates an activation signal used to activate the electronic device to a higher power state in response to receiving a notable signal received from the input device.

Abstract: A system for powering a peripheral device with a host device is described. The system includes N host interface power ports, each adapted for coupling to a corresponding host port on the host device to deliver power to the peripheral device. A current adding unit adds current received from the host device via at least the N host interface power ports to produce a total current. A power terminal is coupled to the peripheral device to send the total current from the current adding unit to the peripheral device.

Abstract: A load device includes a power input having an interface to a power supply; a peripheral power bus including an internal capacitance, and an active switch coupled to the power input and the peripheral power bus for applying power from the power input to the peripheral power bus. The load device also includes a switch controller coupled to the active switch for regulating the in-rush current drawn by the internal capacitance through the active switch while the internal capacitance is being charged.

Abstract: A handheld computing device includes a notification lamp, a melody circuit coupled to the notification lamp for providing a first type notification, an electronic switch coupled to the notification lamp for providing a second type notification, and a notification controller coupled to the melody circuit and the electronic switch for selecting between the notification types. The power consumption of the second type notification is less than that of the first type notification.

Abstract: The present invention discloses a method, program product and system for facilitating efficient development and deployment of features in a voice over internet protocol telephony system comprising protocol specific equipment. The method and program product comprise: developing a feature for deployment in the telephony system using a developer protocol, the developer protocol being independent of any specific VoIP protocol, and performing communication protocol conversion between the developer protocol and a specific VoIP protocol used by the telephony system on feature-related messages in order to communicate with the protocol specific equipment.

Abstract: A system for charging or powering a peripheral device is described. The system includes a connector for connecting the device to the computer, and a software module in the peripheral device that enables the peripheral device to be charged or powered by a computer. The software module includes a first signal module for sending a first signal to the computer that identifies the peripheral device as a hub, and a second signal module for sending a second signal to the computer that indicates that one peripheral device is connected to the hub. A power-charge receptor in the peripheral device contains hardware for powering or charging the peripheral device from the computer.

Abstract: The present invention is a nozzle gun assembly that is axially mounted toward the front of the water gun barrel of a conventional pump-action-type water gun. The nozzle assembly has a nozzle head with a control wheel section. The squirting of the water gun simultaneously causes the actuating member to act against the control wheel, thereby turning the nozzle head on its axis. In this manner, as water is pumped through the nozzle head and out the nozzle, the nozzle head is accordingly rotated so that the stream emitted from the water gun travels an angular path, eg. from left to right. The assembly also has means for disconnecting the actuating member from the control wheel so that the water gun can be utilized in a more conventional manner.
