  • Patent number: 7287014
    Abstract: A plausible neural network (PLANN) is an artificial neural network with weight connection given by mutual information, which has the capability of inference and learning, and yet retains many characteristics of a biological neural network. The learning algorithm is based on statistical estimation, which is faster than the gradient decent approach currently used. The network after training becomes a fuzzy/belief network; the inference and weight are exchangeable, and as a result, knowledge extraction becomes simple. PLANN performs associative memory, supervised, semi-supervised, unsupervised learning and function/relation approximation in a single network architecture. This network architecture can easily be implemented by analog VLSI circuit design.

  • Publication number: 20070233367
    Abstract: The present invention provides key disclosures in three aspects, geo-location information exploration, interaction over geo-locations, and geo-location information sharing. In one aspect, the present invention provides for geo-strolling, a concept of a user navigating to a geographical location on a computer graphically displayed map or environment. The user can be represented by a geo-stroller icon that is visible and programmed for interaction with other geo-strollers present at the same graphically mapped location. This concept is a powerful one because while virtual geo-strollers are not physically located at a place of interest, we can see where their minds are. By tracking the browsing intentions of users, embodiments of the present invention gather information of their interests, making them context compatible for social or business networking as well as other applications.

  • Publication number: 20070205745
    Abstract: A battery management system for managing a plurality of subsystem circuits and functions of a mobile communication device powered by a battery is disclosed. The battery management system includes a battery monitoring circuit a user interface, and a battery management module. The battery monitoring circuit is operable to monitor a present battery capacity and generate a battery capacity signal based on the present battery capacity. The user interface is operable to receive a user-input allocation of battery capacity among the subsystem circuits and functions. The battery management module is operable to receive the user-input allocation and the battery capacity signal, and to selectively disable each subsystem circuit or function when each subsystem circuit or function has depleted its allocation of battery capacity.

  • Publication number: 20070113693
    Abstract: A multi-speed transmission includes first and second output gear sets having co-planar intermeshing gears axially-spaced from one another. Each has a first gear intermeshing with a second gear, one of which is connected for common rotation with an output shaft or a first countershaft and the other of which is connected for rotation about and selectively engagable with the other of the output shaft and first countershaft by a respective output torque-transmitting mechanism. A direct drive torque-transmitting mechanism is selectively engageable for transferring torque from the input shaft to the output shaft when neither of the output torque-transmitting mechanisms is engaged. The first output torque-transmitting mechanism is engaged during underdrive gear ratios and the second output torque-transmitting mechanism is engaged during overdrive gear ratios. The order of engagement of torque-transmitting mechanisms during the underdrive gear ratios may be repeated during the overdrive gear ratios.

  • Publication number: 20070049241
    Abstract: A remote controller device includes a wireless user-operated module and a multi-function module. The wireless user-operated module is operable so as to generate control signals for controlling operation of an electrical appliance, and includes a signal receiver, a sound generator, and a signal processor coupled to the signal receiver and the sound generator. The multi-function module is operable so as to transmit a paging signal for wireless reception by the signal receiver of the user-operated module. The signal processor responds to the paging signal received by the signal receiver of the user-operated module by activating the sound generator to generate an audible sound output.

  • Publication number: 20070036178
    Abstract: A Virtual Communication Environment to support virtual switching engines for layer 2 switches is described. The virtual layer 2 switching engines allow many virtual switches to be created in a CPU or across multiple CPUs in switching hardware. The virtual switch engines reduce the inter-communication costs in memory, CPU, inter-process bandwidth, and fabric bandwidth. This reduction in the cost per Virtual Switch device allows either more virtual switches to be contained within a control plane or more applications per switch control plane.

  • Patent number: 7177606
    Abstract: A method and system for controlling an output signal power level of a wireless transmitter can be created by detecting the signal power level of the transmitter with a detector, selectively attenuating the output signal power level with an attenuator having variable attenuation levels, and monitoring the output signal power level and comparing the output signal power level, as determined by the detector, to a predetermined threshold with a processor. The processor preferably controls the attenuator in accordance with the comparison of the output signal power level and the predetermined threshold.

  • Patent number: 7167528
    Abstract: A method and system for modulating data onto a carrier signal in a plurality of channels, each of the channels having a channel bandwidth, can be created for use in any two-way satellite communication system or other wireless communication application where frequency hopping with or without Doppler compensation is desired. The system preferably includes a digital modulator that outputs a modulated baseband signal, an intermediate frequency modulator that receives the modulated baseband signal and outputs an intermediate frequency signal derived from the modulated baseband signal, a frequency synthesizing system that outputs a synthesized intermediate frequency signal to the intermediate frequency modulator, and a circuit (numerically controlled oscillator) connected to the digital modulator which provides a signal to the digital modulator.

  • Publication number: 20060263724
    Abstract: The invention is directed towards a method for forming a material layer between the liquid and the photoresist layer in immersion lithography. After forming a photoresist layer over the wafer, a material layer is formed between the photoresist layer and the liquid and covering the photoresist layer. The material layer, acting as an interface layer and a barrier layer, can provide a first surface wettable to the liquid (or water), and a second surface opposite to the first surface for good adhesion toward the photoresist layer.
