Abstract: Operating a pointing device in a low power manner by receiving first tracking information from a first tracking device, de-activating the first tracking device when the accuracy of the first tracking information is determined to be inadequate, activating a second tracking device in order to acquire second tracking information when the first tracking device is deactivated, wherein the first tracking device is substantially lower power device that the second tracking device.

Abstract: A touch panel having a transparent capacitive sensing medium configured to detect multiple touches or near touches that occur at the same time and at distinct locations in the plane of the touch panel and to produce distinct signals representative of the location of the touches on the plane of the touch panel for each of the multiple touches is disclosed.

Abstract: The application of a watershed algorithm to pixels and their touch values obtained from a scan of a touch sensor panel to determine patches corresponding to images of touch is disclosed. Prior to applying the watershed algorithm, background pixels having little or no touch values can be eliminated. A primary merge algorithm can then merge adjacent patches together when the saddle point between them is shallow as compared to the peak represented by the patches. However, if two candidate patches for merging have a total number of pixels below a certain threshold, these two patches may not be merged under the assumption that the patches might have been caused by different fingertips. Conversely, if two candidate patches for merging have a total number of pixels above a certain threshold, these two patches can be merged under the assumption that the patches were caused by a single thumb or palm.

Abstract: In one exemplary embodiment, a portable computer having a display assembly coupled to a base assembly to alternate between a closed position and an open position. Palm rest areas are formed by a touchpad disposed on the surface of the base assembly. In an alternative embodiment, a touchpad disposed on the base assembly has a width that extends substantially into the palm rests areas of the base assembly.

Abstract: During a telephone call between a telephone user and an interactive response system, the user is enabled to use only his voice and key presses on a numeric keypad of his telephone to interactively specify information that can be used to control delivery of content to a visual display of, or a storage medium accessible by, a target telephone which may be a land-line phone, a mobile phone, or some other device acting as a telecommunications device. The target telephone has a visual display or a memory to display or store the delivered content, which may include ringtones, text messages, games, wallpapers, ring-back tones, video clips, web pages, applications, or links to information. The user is enabled to engage in an interaction with the response system that is representative of an interaction between the user and a server connected to the Internet. On behalf of the user, a separate interaction is conducted with the server through the Internet based on the representative interaction.

Abstract: A low power tracking device and a method of use thereof is described. The method includes receiving first tracking information from a first tracking device and periodically determining accuracy of the first tracking information. A second tracking device is activated and used to acquire second tracking information when said determining indicates that the accuracy of the first tracking information is inadequate. The first tracking device is substantially lower power device that the second tracking device.

Abstract: A method includes (a) receiving periodic subscription fees from subscribers of a content subscription service, (b) updating an electronically maintained account of the subscriber to reflect an additional amount of scrip corresponding to each subscription fee, and (c) enabling the subscriber to obtain items of content in amounts and at times determined arbitrarily by the subscriber in exchange for amounts of scrip in the subscriber's account.

Abstract: Proximity based systems and methods that are implemented on an electronic device are disclosed. The method includes sensing an object spaced away and in close proximity to the electronic device. The method also includes performing an action in the electronic device when an object is sensed.
