Abstract: A device for sensing hydrogen based on palladium or palladium alloy nanoparticles, wherein the nanoparticles are deposited on a resistive substrate, to permit sensing of less than 1% hydrogen; wherein the nanoparticles are deposited as islands on a continuous resistive layer.

Abstract: A gas sensing mechanism and a gas sensor based on a semiconducting carbon nanotube diode structure are disclosed. The gas sensor operates by detecting the change in conductivity characteristic of the current vs. voltage behavior of an I—N, or I—P junction, in the carbon nanotube. In the presence of electrophilic gas species at the I—N junction, or nucleophilic gas species at the I—P junction, a P—N, or N—P, junction is created by doping of the carbon nanotube by the respective gas species. The resulting change from the undoped, instrinsic i-type to p-type, or n-type, creates a diode structure whose conductivity characteristics can be measured with high accuracy and selectivity.

Abstract: A method for emulating human cognition in electronic form is disclosed. Information is received in the form of a textual or voice input in a natural language. This is parsed into pre-determined phrases based on a stored set of language rules for the natural language. Then, the parsed phrases are determined as to whether they define aspects of an environment and, if so, then creating weighting factors to the natural language that are adaptive, the created weighting factors operable to create a weighted decision based upon the natural language. Then it is determined if the parsed phrases constitute a query and, if so, then using the weighted factors to make a decision to the query.

Abstract: A method for emulating human behavior and actions in an expert mode to control and execute a defined task. The first step is to define a task based application having a task associated therewith that is operable to receive goals and conditions and which goals define the desired results to be achieved when the task is performed. A brain emulation is represented by a plurality of nodes each representing a concept, and interconnecting relationships between select ones of the concepts, which brain emulation is operable to receive information from the task based application and process such information and capable controlling the task based application with the outcome of such processing to achieve the goal of the task based application.

Abstract: A method for modeling human emotion for emulating human behavior, comprising the steps of recognizing the existence of a condition capable of being sensed at least in the abstract in a surrounding environment in which the human behavior is emulated. A first step comprises representing a plurality of human emotions, each with a temporally varying emotion level. A second step comprises representing the condition as having a predetermined relationship with respect to one or more of a linked one of the plurality of human emotions, the predetermined relationship defining the effect that the recognized existence of the condition will have on the linked one or more of the plurality of human emotions. The step of recognizing results in a temporal change to the temporally varying emotion level of the linked one of the plurality of human emotions, such that the presence of conditions in the surrounding environment is reflected in the temporally varying emotion levels of one or more of the represented human emotions.

Abstract: A device for sensing hydrogen utilizes a palladium-nickel alloy of nanoparticles deposited on a substrate between two electrodes connected to an electrical circuit. As hydrogen is sensed the resistance of the device changes, which can then be measured and monitored.

Abstract: A high voltage driver with capacitive coupling that is useful in the presence of the high power supply ripple common with higher-voltage systems. It permits extreme ranges of duty cycle, but without the limitations of transformer magnetics, or the increased complexity of optical coupling methods. It is also robust in the presence of voltage transients created by high-voltage arcing to the output drive-line.
