Disclosed are methods for non-destructively measuring in vitro the effect on cellular metabolism of the addition to animal cells in culture of a soluble molecule potentially capable of perturbing the biological state of the cells, such as a drug or drug candidate, a toxin, a ligand known or suspected to bind to a cell surface receptor, a nutrient, a cytokine, a growth factor, a chemokine, a metabolism inhibitor or stimulator. Also disclosed are methods for measuring cell viability, vitality, or quality, e.g., in anticipation of the execution of an experiment on the cells. The measurements are done by observing alteration in the rates of consumption or production of extracellular solutes related to aerobic and anaerobic cellular metabolism, such as oxygen, protons, nutrients, carbon dioxide, lactate, or lactic acid. The methods are particularly useful in drug discovery efforts, such as cancer drug discovery and searches for modulators of cellular metabolism.

A hydrogen generating system regulates its rate of hydrogen generation by monitoring one or more parameters of the hydrogen generation process and then providing relative movement between the fuel tank and the catalyst chamber so as to increase or decrease the rate of hydrogen generation.

In the disclosed embodiments, the catalyst chamber is disposed in a tank containing the fuel. The relative movement provided moves the catalyst chamber toward the fuel solution so as to increase the rate of hydrogen generation and moves the catalyst chamber away from the fuel solution to decrease such generation. Advantageously, such self-regulation can be provided without an external power source and can be varied to meet the requirements of different commercial applications. The overall system can be readily fabricated using commercially available parts.

A source and/or method of generating quantum-correlated and/or entangled photon pairs using parametric fluorescence in a fiber Sagnac loop. The photon pairs are generated in the 1550 nm fiber-optic communication band and detected by a detection system including InGaAs/InP avalanche photodiodes operating in a gated Geiger mode. A generation rate>10³ pairs/s is observed, a rate limited only by available detection electronics. The nonclassical nature of the photon correlations in the pairs is demonstrated. This source, given its spectral properties and robustness, is well suited for use in fiber-optic quantum communication and cryptography networks. The detection system also provides high rate of photon counting with negligible after pulsing and associated high quantum efficiency and also low dark count rate.

A cardiac rhythm management system provides an increase in pacing rate as a combination of responses to three characteristics of a relative-temperature signal: a dip, a positive slope, and a positive magnitude. The relative-temperature signal is the difference between a short-term and a long-term temperature average. A dip produces a limited and temporary rate increase having a first proportionality. A positive slope produces a rate increase with a second proportionality. A positive magnitude produces a rate increase with a third proportionality. The dip response seeds the slope response to provide a seamless and immediate rate transition after a dip. The cardiac rhythm management system limits and filters the sum of the rate increases to provide a sensor indicated rate, which is used to stimulate the heart.

An insulating shield may be used to catch reaction debris from the anodes. A removable inert layer may cover the electrodes. The use of cell pressure may regulate the rate of hydrogen generation. The hydrogen generator may have a separate catalyst chamber, and the hydrogen generator may also function as a battery.

An apparatus, system, and method are disclosed for estimating particulate production from a diesel engine. Engine conditions such as fuel rate, exhaust gas recirculation, and fuel injection timing are determined. Based on empirical evidence or theoretical calculations, or both, particulate production markers, each indicating a level of particulate production, are assigned to each engine condition. The markers are combined and the combined marker is used to interpolate between a minimum and a maximum level of particulate production from the engine to estimate a particulate production rate. The production rate may be combined with an oxidation rate to determine a particulate accumulation rate, which may in turn be combined with a particulate load estimate to produce a combined particulate load estimate. The combined estimate may be used to determine whether to initiate regeneration of a diesel particulate filter.

The invention comprises emergency call management apparatus (31) and a mobile station (1). The emergency call management apparatus (31) monitors the emergency call generation rate, which is indicative of the rate of generation of emergency calls in a network, and on the basis of the result of this monitoring, transmits state information indicative of the restriction state of communication in that network, when the emergency call generation rate attains a preset condition. The mobile station (1) has emergency number information indicative of a number to be dialed to make an emergency call, and transmits, on the basis of the emergency number information and the received state information, a connection request to the network when the restriction state is a state in which only that emergency call is accepted and the number that has been dialed is the number to be dialed to make that emergency call. This provides a higher probability that an emergency call will be processed in situations in which there is a high rate of generation of emergency calls. This is because in such situations the network only has to process emergency calls.

The invention provides a flexible panel curved-surface adhering device and method. Sucking hole channels are formed in a flexible panel sucking table, a second working contact surface of the flexible panel sucking table is divided into multiple areas, any one area can be independently controlled to release vacuum of the sucking hole channel in the area so as to stop suction to a flexible panel in the area. During suction, the sucking hole channel in one area is selected to firstly release vacuum, then the vacuum of the sucking hole channel in the area adjacent to the area without vacuum is released, circulation is performed till the vacuums of the sucking hole channels in all the area are released, accordingly flexible panels are sequentially adhered to a curved-surface cover plate, air is extruded out of the space between the two parts, and the air bubble generation rate is reduced. The deformation of a buffer material for the flexible panel sucking table is not produced in implementation. Therefore, the product quality problem caused by higher bubble generation rate due to poor quality, hardness and deformation effect of the buffer material or the service life of the buffer material is well solved.

The method is used for locally testing underground soil contamination by determining the generation rate of a first contaminant fluid in porous soil. The method includes the steps of making a hole of known dimensions in the soil, with the hole defining a first and a second spaced-apart portions; covering the hole, so as to define a closed volume in the hole; constantly injecting a second fluid in the hole at a constant given flow rate at said first portion of the hole, while simultaneously collecting fluid samples at the above-mentioned constant given flow rate at the second portion of the hole; measuring the concentrations of the first contaminant fluid from the fluid samples collected at known time intervals; and computing the generation rate of the first contaminant fluid, from the known volume of the hole and from the concentrations previously measured and originating from samples collected at the known time intervals. The probe used to carry out the above-described method has a rigid hollow body in which a semi-rigid tube is axially slidable. The probe can be driven through the ground and then partially retracted, to form a hole of known dimensions. The flexible tube is axially displaced so that its lower bored extremity is positioned near the bottom end of the hole, while the hollow rigid body of the probe has an annular opening about the tube at the upper end of the hole. The second fluid can then be circulated in the hole between the lower end of the tube and the annular opening of the probe rigid main body.
