A method called the evolvable interference management (EIM) method is disclosed in this patent for avoiding interference and collision and increasing network throughput and energy efficiency in wireless networks. EIM employs sensitive CSMA/CA, patching approaches, interference engineering, differentiated multichannel, detached dialogues, and/or spread spectrum techniques to solve the interference and QoS problems. EIM-based protocols can considerably increase network throughput and QoS differentiation capability as compared to IEEE 802.11e in multihop networking environments. Due to the improvements achievable by EIM, the techniques and mechanisms presented in this application may be applied to obtain an extension to IEEE 802.11 to better support differentiated service and power control in ad hoc networks and multihop wireless LANs. New protocols may also be designed based on EIM.

The use of one or more proximity sensors in combination with one or more touch sensors in a multi-touch panel to detect the presence of a finger, body part or other object and control or trigger one or more functions in accordance with an “image” of touch provided by the sensor outputs is disclosed. In some embodiments, one or more infrared (IR) proximity sensors can be driven with a specific stimulation frequency and emit IR light from one or more areas, which can in some embodiments correspond to one or more multi-touch sensor “pixel” locations. The reflected IR signal, if any, can be demodulated using synchronous demodulation. In some embodiments, both physical interfaces (touch and proximity sensors) can be connected to analog channels in the same electrical core.

Apparatuses and methods to sense proximity of an object and operate a proximity sensor of a portable device. In some embodiments, a method includes receiving an ambient light sensor (ALS) output, and altering, based on the ALS output, an effect of a proximity sensor output on control of a proximity determination. The ALS sensor and the proximity sensor may be located adjacent to an earpiece of a portable device. In some cases, the proximity determination may be a proximity of an object to the proximity sensor, and altering the effect may include changing the proximity of the object from a proximity greater than a first threshold to a proximity less than the first threshold. Other apparatuses and methods and data processing systems and machine readable media are also described.

In some aspects, each cell in the communications system can be designed to operate in accordance with a set of back-off factors that identify the reductions in peak transmit power levels for the channels associated with the back-off factors. The back-off factors are defined to provide the required power to a large percentage of the users while reducing the amount of interference. In some other aspects, the cells operate using an adaptive reuse scheme that allows the cells to efficiently allocate and reallocate the system resources to reflect changes in the system. A reuse scheme is initially defined and resources are allocated to the cells. During operation, changes in the operating conditions of the system are detected and the reuse scheme is redefined as necessary based on the detected changes. For example, the loading conditions of the cells can be detected, and the resources can be reallocated and/or the reuse scheme can be redefined. In yet other aspects, techniques are provided to efficiency schedule data transmissions and to assign channels to users. Data transmissions can be scheduled based on user priorities, some fairness criteria, system requirements, and other factors. Users are assigned to available channels based on a number of channel assignment schemes. Channel metrics are also provided, which can be used to prioritize users and for channel assignments.

An apparatus, method and system are disclosed for visually constructing and rapidly delivering distributed applications. The system includes a virtual appliance apparatus and a composite appliance apparatus, as well as a system for virtualizing hardware resources and for provisioning, executing and scaling distributed applications.

In a parallel operational processing device having an operational processing unit arranged between memory blocks each having a plurality of memory cells arranged in rows and columns, the respective columns of each memory block are alternately connected to the operational processing units on the opposite sides of the memory block. By selecting one word line in one memory block, data can be transferred to two operational processing units. The number of the word lines selected per one operational processing unit is reduced, and power consumption is reduced. The bit operation units and sense amplifiers/write drivers of the operational processing units have arrangement pitch conditions mitigated and are reduced in number, and an isolation region between the memory blocks is not required and the layout area is reduced. Thus, the parallel operational processing device with a layout area and the power consumption reduced, can achieve a fast operation.

Disclosed embodiments comprise an energy harvesting computer device in association with a communication device comprising interactive user interface operatively configured with CMOS multiple antennas on chip for boosting signal receptions and for providing faster data transmission speed.

Embodiments provide communication apparatus operable to enhance mobile communication efficiency with touch sensitive display comprising energy harvesting platform in communication with a charging circuit board configured with memories, processors, sensors, and modules. Embodiments further provide a gaming device, a wireless media device configured with touch pads comprising sensors being embedded in silicon substrate and fused in nano-fiber/microfiber material having excellent electrical characteristics. Certain embodiments provide communication apparatus configured for voice enabled applications comprising human voice auditory operable to convert text into voice auditory and/or voice auditory into text applications.

A method for adaptively load balancing user sessions to reduce energy consumption includes identifying a session type for each of a plurality of user sessions. A server group is defined, providing access to a subset of the user sessions having a common session type. A power management schedule is also defined for the server group. The method includes consolidating, onto at least one server in the server group, the subset of user sessions. In still another aspect, a method for reducing energy consumption by dynamically managing power modes for a plurality of servers, includes monitoring, via a power monitoring agent, a level of load on one of the servers. A power management console generates a power management schedule for a server, responsive to the monitored level of load. Responsive to the power management schedule, a power management controller dynamically controls a level of power for the server.
