Methods, systems and devices are described for temporarily or permanently evacuating stagnating air from a diseased lung area, typically for the purpose of treating COPD. Evacuation is accomplished by displacing the stagnant CO₂-rich air with a readily diffusible gas using a transluminal indwelling catheter specially configured to remain anchored in the targeted area for long term treatment without supervision. Appropriate elevated positive gas pressure in the targeted area is then regulated via the catheter and a pneumatic control unit to force under positive pressure effusion of the diffusible gas out of the area into neighboring areas while inhibiting infusion of other gases thus effecting a gradual gas volume decrease and deflation of the targeted area.

A method for measuring current in each phase of a three-phase inverter driven motor is based on the three-phase inverter being controlled in a PWM mode by three PWM signals including the use of a common DC-link current sensing resistor. The current on the sensing resistor is intermittently sampled. The method includes determining a modulation index for the voltage demand set by a motor controller. Based on specific mutual duty cycle conditions of the three PWM phase driving signals, sampling windows of sufficient duration are created for allowing distinct sampling of two of the phase currents.

What is claimed is an inspection device for in-tube monitoring of main pipelines by the method of ultrasonic wall thickness metering realized in a device traveling inside the pipeline and performing measurements, acquisition of measurement data and their interpretation. The device comprises a probing pulse generator, an ultrasonic transducer, an amplifier, a comparator with an analog input, a digital timer, a processor and a data storage module, and a controlled reference voltage source connected in series. The output of said reference voltage source is connected to the reference voltage input of the comparator, said reference voltage source being capable of setting at least two different voltages at its output.

The comparator output is connected to one of the control inputs of the reference voltage source that allows one to switch threshold values in the comparator, when recording the ultrasonic pulses, to use one threshold value to record the moment of reception of the ultrasonic pulse reflected from the internal wall of the pipeline using another threshold value of the comparator to record the moment of reception of the ultrasonic pulse reflected from the external wall of the pipeline using the other threshold value. Thus, the operator can perform direct measurements of the transit time of the ultrasonic pulses in the pipe wall allowing him to increase the distance monitored per one pass of the device, and to increase the accuracy of measurements and the rate of hardware data processing compared to the prototypes known in the art.

An idling stop control of the invention attains an auto start and an auto stop of an engine. At a time point t1, pre-set stop conditions are met to cut off a fuel supply to the engine. Preset starting conditions may be met at a time point t2 when the engine still continues rotating in a normal direction by the inertial force. In this state, the idling stop control starts cranking the engine. The preset starting conditions may be met at a time point t4 when a piston does not complete a compression cycle immediately before a stop of the engine but is pressed back by the compressed air to rotate the engine in a reverse direction. In this state, the idling stop control waits until cancellation of the reverse rotation of the engine and then starts cranking the engine. The arrangement of the invention desirably ensures a quick start of the engine, while effectively preventing an excess stress from acting on a gear mechanism, which connects a starter motor to the engine.

A method and apparatus for augmenting an external voltage regulator with a shunt integrated voltage regulator is disclosed. In one embodiment, an integrated circuit (IC) includes a load circuit coupled to a supply voltage node. The supply voltage node is electrically coupled to receive a supply voltage from an external voltage regulator. The IC also includes a shunt integrated voltage regulator coupled to the supply voltage node and implemented on the same IC die as the load circuit. If the supply voltage falls below a specified value (e.g., to increased current demand), the integrated voltage regulator may begin supplying current to the load. This may cause the supply voltage to return to within its specified range of the specified value, while allowing the external voltage regulator sufficient time to respond to the increased current demand. Thus, voltage droops on the supply voltage node may be minimized.

A system and method for recording magnetic resonance images with reduced relaxation-related artifacts. The system and method improve the conventional methods for acquiring magnetic resonance images of in vivo tissue by augmenting the procedures for eliminating artifacts caused by motion with procedures for eliminating artifacts caused by spin of the magnetic resonance-active nuclei in the specimen of interest. One procedure to eliminate such spin inhomogeneities is to require a delay defined by the time N*T₁, where N is a numerical value greater than or equal to 5 and T₁ is the characteristic time constant for decay of spins back to the equilibrium longitudinal state. Another procedure uses a value of N less than 5.

Systems and methods are configured to manage streaming video content. A first time length specification for a content pod is accessed. If a determination is made that a response to a request for ancillary content of a duration corresponding to the first time length of the content pod includes ancillary content of insufficient duration to populate the first time length of the content pod, the content pod time length is reduced. Ancillary content items associated with the response to the request are streamed to a user device as part of a streaming channel comprising primary content having scheduled start times. A primary content item, having a scheduled start time, is streamed to the user device after the items of ancillary content, and earlier than the scheduled start time of the item of primary content.
