摘要:
In a cellular radio communications system, handoff of a mobile terminal from a serving base station to an adjacent base station is performed using two separate fuzzy logic procedures for handoff triggering and handoff targeting. For triggering, inputs to the fuzzy logic procedure are the signal strength for communications with the serving base station, a time since a failure to complete execution of a handoff, and, for mobile-assisted handoff (MAHO), signal strengths of communications between the mobile terminal and each of the adjacent base stations. If handoff is triggered, then handoff targeting is performed at a central unit. For targeting, inputs to the fuzzy logic procedure are the monitored signal strengths between the mobile terminal and each of the adjacent base stations, supplied either from the mobile terminal using MAHO or from the base stations, and the current loads of the adjacent base stations. The targeting determines preferences for handoff of the mobile terminal to the different adjacent base stations, handoff then being executed in accordance with these preferences.

A method for preparing a silicon monoxide composite material includes: a first stage: introducing a protective gas into a vapor deposition oven, and pre-heating a silicon monoxide raw material, such that a part of the silicon monoxide raw material is subjected to a disproportionation reaction; a second stage: continuously introducing the protective gas and introducing a carbon source gas, and subjecting the pre-heated silicon monoxide raw material to a chemical vapor deposition to form carbon nanotubes on a surface of silicon monoxide; and a third stage: after a predetermined time period, stopping introducing the carbon source gas, and stopping introducing the protective gas until the vapor deposition oven is cooled to room temperature, to prepare the silicon monoxide composite material. During the preparation process, no extra catalyst needs to be added, a product of the previous disproportionation reaction may act as a catalyst for the growth of the carbon nanotubes.

A method, including: obtaining, with a computer, an initial geophysical model; modeling, with a computer, a forward wavefield based on the initial geophysical model with wave equations including a second order z-derivative in a rotated coordinate system that accounts for a tilted transverse isotropic (TTI) medium; modeling, with a computer, an adjoint wavefield with adjoint wave equations including a second order z-derivative in a rotated coordinate system that accounts for a tilted transverse isotropic (TTI) medium, wherein the wave equations and the adjoint wave equations include relaxation terms accounting for anelasticity of earth in an update of a primary variable and an evolution relationship for the relaxation terms; and obtaining, with a computer, a gradient of a cost function based on a combination of a model of the forward wavefield and a model of the adjoint wavefield.

There is described a portable electronic device capable of managing screen orientation. The portable electronic device comprises a display, a motion sensor, an image sensor and a processor. The display provides an image at a first orientation. The motion sensor attempts to detect a rotation of the portable electronic device. The image sensor attempts to detect one or more body features. The processor determines a second orientation of the image at the display based on the rotation detected at the motion sensor and/or the body feature or features detected at the image sensor. The portable electronic device may determine an orientation of the image at the display in response to detecting the rotation at the motion sensor and/or the body feature or features at the image sensor.

A system and method for selecting a wireless network is disclosed. The method relates to selecting a wireless network from a plurality of wireless networks. A variation of the invention includes selecting a new platform from a plurality of platforms offered by the current service provider according to a service request from the wireless device. The method comprises determining a requested service associated with the wireless device, determining whether one of the plurality of wireless networks can provide the requested service, and, if one of the plurality of wireless networks can provide the requested service, choosing the one wireless network of the plurality of wireless networks. The method further involves using a variety of parameters in determining which wireless network to choose for servicing the requested service from the wireless device. These parameters include quality of services, application supported, or other business factors such as roaming agreements, traffic load and cost of services. The system comprises at least one wireless network node, a wireless device, and a plurality of wireless networks communicating with each other. Either the wireless device or network node may operate to decide based on the services the wireless device user requires on which network the user will receive service from. The network assignment is accomplished to maximize the speed, cost and efficiency of transmission.

摘要:
A thermal bubble jetting device including a substrate. A superoleophobic, textured surface is positioned on the substrate. The textured surface comprises one or more gaps configured for holding a gas. A receptacle is positioned in fluid communication with the textured surface. Both an inlet and nozzle are in fluid communication with the receptacle. The device includes a heater mechanism configured to expand a gas in the one or more gaps so as to sufficiently increase pressure in the receptacle to force liquid through the nozzle.
