Abstract: A method comprises encoding data by a first device, displaying the encoded data on a display of a first device, capturing an image of the encoded data displayed on the display with a camera associated with a second device, and converting the image to the data by the second device.

Abstract: Energy-aware software control in a computer system requires a plurality of displays. At least two of the displays have diverse attributes that enable reduction in the energy consumption of the computer system. The energy-aware software control involves profiling screen usage patterns and their impact on energy consumption by the displays and in turn by the computer system. The profiling results in an energy model. A determination is made when to activate (or deactivate) the energy-aware software control of the displays in order to decrease their energy consumption. Under the energy-aware software control, and guided by the energy model, a screen fashioned by one or more applications is divided up into sub-screens. Then, the energy needs associated with the sub-screens are matched to particular displays in accordance with their respective attributes and the energy model. The idea is to put the sub-screens on view by matched and likely different displays without significantly diminishing the user experience.

Abstract: A combination modem including at least one line connector that is configured for coupling to a transmission medium, analog modem logic that is capable of performing analog modem communications via the transmission medium, digital modem logic that is capable of performing digital modem communications via the transmission medium, a bus interface that enables communication with a computer via an expansion bus of the computer, and processing logic. In this manner a single modem expansion card supports both analog and digital modem technologies using only one slot of an expansion bus of the computer. The analog modem logic may support 56K technologies, such as K56Flex™, V.90, etc., or any combination thereof. The digital modem logic may be according to any type of xDSL, such as ADSL, or U-ADSL, etc. The modem may operate as an analog modem, a digital modem, or as both at the same time with or without a POTS splitter.

Abstract: A networking modem capable of full duplex communication over a telephone line is adapted for use as a component of a computer system. The modem comprises a digital signal processor (DSP) capable of implementing a plurality of digital modulation and demodulation techniques, including pulse position modulation (PPM), quadrature phase shift keying (QPSK), and quadrature amplitude modulation (QAM). The DSP implements a digital phase locked loop (DPLL), including a carrier NCO and a carrier detector to synchronize local demodulation timing to an incoming carrier signal. Available processing options include spectral agility for optimizing channel capacity, symbol shaping to compensate for evolving channel conditions, and echo cancellation.

Abstract: A computer's representation and handling of dial-up and network applications are standardized. A LAN connection is established on a session basis only when required, enabling a user or system administrator to have the same control over the LAN connection as is typically exercised over a WAN connection. Examples of WAN connection features that are available to the LAN connection are the maintenance of billing information, access control, authentication and verification. In addition, an application can be represented by several different icons configured to utilize different procedures and communication devices.
