An intravenous fluid heater is provided that is dimensioned so as to be wearable adjacent a patient's intravenous fluid infusion situs. In one embodiment, the heater includes a heat exchanger for defining a flow path through the heater for fluid to be infused via the infusion situs. At least one controllable heating element is provided for heating the fluid in the flow path by heat conduction thereto through the heat exchanger. Sensors are included for sensing respective temperatures of entering and exiting fluids of the flow path. A controller controls, based upon the temperatures of the exiting fluids, heating of the fluid in the flow path by the heating element so as to cause the fluid in the flow path to be substantially uniformly heated to a desired infusion temperature prior to exiting the heater.

Systems and methods are disclosed that facilitate providing page-level database restore functionality upon detection of a corruption event. Updates to a data page in a database can trigger generation of a snapshot of the data page, and an update log can be maintained that stores information related to page updates. Subsequent snapshots can be generated at predetermined intervals and can trigger truncation of a log segment and initiation of a new log segment. Upon detection of page corruption, a most-recent uncorrupt snapshot of the corrupt page can be identified, copied to the location of the corrupt page in the database, and modified according to the log segment associated with the uncorrupt snapshot to make the page current as of the corrupting event, all of which can be performed to restore the database without having to take the database offline.

A multi-function controller for a water heater is advanced comprising a control panel and a plurality of sensors that monitor a variety of functions that impact the operation of a water heater. A flammable gas sensor, placed in proximity to the air intake, detects the presence of an unsafe concentration of gas and issues a signal to the control panel, which subsequently discontinues the operation of the burners. Detection of a blocked vent pipe is achieved by a carbon monoxide sensor placed near the draft hood. The control panel is equipped with circuitry which monitors usage of the heater for a specified time period to develop a pattern of use. Subsequent to the monitoring period, the controller will activate the burners a predetermined time prior to an anticipated period of high use. During periods of low use, the controller will decrease the temperature to which the water is to be heated, thereby resulting in a more efficient heater. Non-volatile memory records data from the sensors so that the operation status of the heater may be ascertained subsequent to a power outage. The control panel contains a plurality of visual alarms, each of which corresponds to a sensor. Consequently, repair and maintenance are simplified because the cause of a malfunction is quickly recognized.

An image jaggedness filter is disclosed that can be used to detect the presence of ungrounded objects such as water droplets or coins, and delay periodic baseline adjustments until these objects are no longer present. To do otherwise could produce inaccurate normalized baseline sensor output values. The application of a global baseline offset is also disclosed to quickly modify the sensor offset values to account for conditions such as rapid temperature changes. Background pixels not part of any touch regions can be used to detect changes to no-touch sensor output values and globally modify the sensor offset values accordingly. The use of motion dominance ratios and axis domination confidence values is also disclosed to improve the accuracy of locking onto dominant motion components as part of gesture recognition.

In particular, the absorbent articles comprise at least one chemiresistor capable of detecting the presence of volatile organic compounds associated with a body waste. When a body waste is detected, an indicator means signals a caregiver and / or a user of the absorbent article that an insult has occurred

A capacitive sensor comprises patterned electrodes and printed wires of conductive material integrated with sensing circuits on flexible circuit substrates. The flexible circuit substrates are fingered or otherwise elongated to distribute sensing points to the limbs in a toy doll or animal, or squares on a board game. Such sensing points can detect the presence of a finger even though actual contact is not made by measuring the proportions and changes in stray capacitance attaching to the various electrodes. Touch sensors are therefore possible even when the capacitor sensor's sensing points are covered by a doll's plastic skin or a plush animal's fur. Including an interlayer of open cell foam under the flexible circuit substrate further implements a pressure sensor because applied pressures will deform the geometries of the capacitor electrodes and dielectrics enough to produce a measurable change in capacitance.

An improved data exploration system and method that can be used to analyze and to explore complex data sets involving multiple data dimensions and multi-variable data presentations. The data exploration system generates visual representations of complex data sets in map, table, and tree view formats. In each of these view formats, both the appearance and the arrangement of the symbols representing the data sets are based on the data itself to facilitate the comprehension of patterns and information relationships within the data sets. Further, the data can be viewed at different levels of density to perform detailed analysis of the data, and to detect the presence of overall trends within the data. Moreover, the data exploration system performs a suite of calculation operations to cast the data in different forms, and to facilitate the acquisition, integration, and analysis of the data.

A system is disclosed for preventing air from entering a first catheter or cannula of a multi-catheter system. Air is prevented from entering the proximal end of the first catheter by an axially elongate chamber having an impeller, the chamber being affixed to the proximal end of the first catheter. The first catheter is affixed at an offset location, near the periphery of the chamber. The impeller is driven by a motor drive and imparts rotational energy to the fluid within the chamber forcing any air within the chamber to migrate to the center of the chamber by buoyancy effects. The air is removed through a port near the centerline of the chamber. Liquid removed with the air is returned to the chamber to minimize liquid loss during the procedure. Hemostasis valves or seals can be provided at the entrance and the exit of the chamber. A second catheter inserted through the chamber and into the first catheter is unable to entrain gas into the first catheter because any gas that enters the chamber is routed to the centerline of the chamber where it is removed. The first catheter can be a cannula or an introduction sheath, devices suited for endovascular access into the mammalian cardiovascular system where pressures may fall below ambient room pressure, a condition, which could encourage the possibility of air embolism to a patient. Inflow of fluid from an external pump scrubs the second catheter shaft of air bubbles attached by surface tension.

The invention provides an autonomous vehicle with a video camera that merges images taken a different light levels by replacing saturated parts of an image with corresponding parts of a lower-light image to stream a video with a dynamic range that extends to include very low-light and very intensely lit parts of a scene. The high dynamic range (HDR) camera streams the HDR video to a HDR system in real time—as the vehicle operates. As pixel values are provided by the camera's image sensors, those values are streamed directly through a pipeline processing operation and on to the HDR system without any requirement to wait and collect entire images, or frames, before using the video information.

A system for distinguishing between a first condition corresponding to a living subject being directly in contact with an object of interest, and a second condition corresponding to the absence of contact between the living subject and the object of interest. A transducer, which may be a MEMs sensor, is disposed in predetermined relationship to the object of interest and produces a transducer signal responsive to a pressure wave resulting from the living subject being directly in contact the object of interest. A database stores data corresponding to the first condition and may contain additional data corresponding to the second condition. A processor calculates an algorithm of a non-linear short-term frequency-selective energy distribution of the transducer signal over time to produce transducer signal data. An arrangement, which may be a human listener or a processor system, determines a threshold between the first and second conditions in response to the transducer signal data and the first and second data. The direct contact may be a tap or stroking contact by a living subject. The transducer can be disposed within, or on the exterior of, the object of interest.
