The system retrieves information from the internet using multiple search engines that are simultaneously launched by the search engine commander. The commander is responsive to a speech-enabled system including a speech recognizer and natural language parser. The user speaks to the system in natural language requests, and the parser extracts the semantic content from the user's speech, based on a set of goal oriented grammars. The preferred system includes a fixed grammar and an updatable or downloaded grammar, allowing the system to be used without extensive training and yet capable of being customized for a particular user's purposes. Results obtained from the search engines are filtered based on information extracted from an electronic program guide and from prestored user profile data. The results may be displayed on screen or through synthesized speech.

A method and apparatus uses a stored model of a building system to render an image showing a condition sensed of the building control system on a mobile display unit.

A method, computer program, and system for real-time signal analysis providing characterization of temporally-evolving densities and distributions of signal features of arbitrary-type signals in a moving time window by tracking output of order statistic filters (also known as percentile, quantile, or rank-order filters). Given a raw input signal of arbitrary type, origin, or scale, the present invention enables automated quantification and detection of changes in the distribution of any set of quantifiable features of that signal as they occur in time. Furthermore, the present invention's ability to rapidly and accurately detect changes in certain features of an input signal can also enable prediction in cases where the detected changes associated with an increased likelihood of future signal changes.

A mattress has a sensor pad affixed on a top surface thereof. The sensor pad has (i) a matrix array of plural pressure sensors, (ii) plural row conductors, and (iii) plural column conductors. Each intersecting row and column conductor provides an electrical signal from a corresponding sensor when pressure is applied thereto. The sensor pad has plural through-holes therein disposed between the plural row conductors the plural column conductors, respectively. Preferably, at least one patient-mounted physiological sensor is configured to provide an output signal corresponding to a patient physiological parameter. An electronic unit is mounted inside the mattress and is configured to receive signals from the sensor pad. The electronic unit has a data storage unit preferably storing (i) patient identification information, (ii) patient physiological information, and (iii) mattress information. A wireless transmitter is coupled to the electronic unit and is configured to wirelessly communicate at least the stored patient physiological information to an off-mattress device.

A system and a method for circuit compliance compensated volume control in a patient respiratory ventilation system having a flow regulated feedback servo control loop, a volume delivery controller, and a patient volume observer. In the flow regulated feedback servo control loop, an estimate of patient volume is used for feedback control, such that a tidal volume is achieved upon servo regulation, and the peak inspiratory flow is modulated based on volume error between the set tidal volume and the estimated patient volume. Thereby, a constant inspiratory time and a constant I:E ratio can be maintained. In the volume delivery control, the feedback volume error is normalized to a volume error percentage, and the gain of the controller is dynamically changed based on the volume error percentage, such that the controller effort can be minimized when the volume target is approached. The patient volume observer is operative to estimate the patient delivered volume based on the estimated circuit volume and the measured net delivered volume, while the measured net delivered volume includes effects of leaks and valve dynamics and is synchronously captured with true patient breathing.

Apparatus and method for dispensing a gas using a gas source coupled in selective flow relationship with a gas manifold. The gas manifold includes flow circuitry for discharging gas to a gas-using zone, and the gas source includes a pressure-regulated gas source vessel containing the gas at superatmospheric pressure. The pressure-regulated gas source vessel can be arranged with a pressure regulator at or within the vessel and a flow control valve coupled in flow relationship to the vessel, so that gas dispensed from the vessel flows through the regulator prior to flow through the flow control valve, and into the gas manifold. The apparatus and method permit an enhancement of the safety of storage and dispensing of toxic or otherwise hazardous gases used in semiconductor processes.

An improved weight distribution sensory device with integrated controls is provided. Such a weight distribution sensory device, often referred to as a balance platform, may include a chassis for supporting a user, pressure sensors and control sensors coupled to the chassis, and a processor. The pressure sensors generate pressure data regarding the compression force from the weight of the user on the chassis. The control sensors are located on a forward dorsal portion of the chassis, and may generate control data when manipulated by the user. The control sensors include at least one proximity sensor which senses object proximity (such as the user's foot) in a narrow band above the sensor along the y-axis. The processor may then receive the pressure data and the control data, and may generate a total weight of the user and a weight distribution of the user, and action data for the user by cross referencing the weight distribution with the control data.
