            <description><![CDATA[An excitation AC signal biased by a predetermined DC voltage is applied to a coil to allow a DC voltage component in a coil output signal to contain failure information about disconnection, partial disconnection, or the like of the coil. The DC voltage component contained in the coil output signal is detected, and the detected DC voltage is provided as an offset voltage for a failure diagnosis. Further, to check a peak level of the excitation AC voltage, a DC voltage corresponding to the peak level may be contained in the offset voltage. A differential amplifier circuit for obtaining a difference between a coil detection output AC voltage component and a reference AC voltage component outputs an obtained differential signal offset by the offset voltage. Accordingly, the differential signal containing the offset voltage as the failure information is transmitted to a circuit for torque measurement as a torque detection signal via a single output line. The circuit for torque measurement provides the torque detection data based on the transmitted differential signal and at the same time extracts the offset voltage to use it for the failure diagnosis.]]></description>

Some embodiments described herein pertain to a load and damage identification techniques that utilize one sensor. Several passive force estimation techniques are presented. Some techniques use either the shape or the amplitude of the magnitude of the applied force in the frequency domain. Several techniques iteratively reduce an underdetermined set of equations of motion into many overdetermined systems of equations to solve for the force estimates. The techniques are shown to locate and quantify impulsive impacts with over 97% accuracy and non-impulsive impacts with at least 87% accuracy. Impacts not acting at a specific input degree of freedom are also accurately located depending on the distance away from the modeled input degrees of freedom, and damaging impact forces are quantified by making assumptions about the impulsive nature of the applied force.]]></description>

            <description><![CDATA[A device for applying a force to a planar surface includes a tub, a cavity, a membrane, and an opening. The tub includes a bottom wall, at least one sidewall, and a cavity defined between the bottom and sidewalls. The membrane is disposed within the cavity and a perimeter edge of the membrane is fixed to the tub. The opening is formed in the tub and adapted to receive a pressurized fluid to fill a portion of the cavity below the membrane to displace at least a portion of the membrane away from the bottom wall to apply a force to the planar surface.]]></description>

            <description><![CDATA[In a gas sensor, when an arithmetical mean roughness Ra of an inner periphery of a metal tube 95 is 1 μm or less and end portions 93 and 94 of U-springs 92 are formed as curved contact portions, the end portions 93 and 94 of the U-springs 92 can slide smoothly along the inner periphery of the metal tube 95. Therefore, when vibration is applied to the gas sensor, the U-springs 92 can be prevented from being caught in the inner periphery of the metal tube 95, and the vibration can be absorbed by an elastic function of the U-springs 92. Even if the gas sensor vibrates, defective contact between a sensor element 20 and contact fittings 71 and wear and cracks in the sensor element 20 are less likely to occur. That is, the gas sensor resistant to vibration can be obtained.]]></description>

            <description><![CDATA[A determination oxygen storage amount used to determine whether a catalyst is degraded is a value obtained by applying a correction amount for removing error caused by response delay time of an output signal of an oxygen sensor to an oxygen storage amount calculated every short time. The correction amount is a value that is calculated using slopes stored in memory, i.e., the slopes for the number of storage cycles (>the short time) corresponding to the response delay time, or the like, and becomes more accurate as a value corresponding to the error as the storage cycle becomes relatively shorter with respect to the response delay time and the number of the slopes stored in the memory increases. The necessary storage capacity of the memory is inhibited from increasing excessively even if the number of the slopes stored in the memory is large.]]></description>

            <description><![CDATA[A method for controlling or monitoring firing systems and for monitoring buildings having gas burners using spectroscopy, provides at least one wavelength-tunable monochromatic light source. An absorption spectrum of a measuring gas is received with at least one photodetector in an absorption path with spectral tuning of the light source, and the concentration of target gases carbon monoxide (CO) and methane (CH4) can be determined simultaneously during tuning of the light source. A device for carrying out the method includes a monochromatic laser diode, in particular a VCSEL, an absorption path in the exhaust gas region or a space endangered by leakage, a photodetector for receiving light passed through the absorption path, and an evaluation unit for determining the concentration of target gases based on the absorption spectrum covered during the laser or laser diode tuning. The method and device are applied in laser-optical gas sensors in gas firing systems.]]></description>

            <description><![CDATA[An improved method of breath sampling, particularly adapted for use in connection with motor vehicle alcohol breath monitoring devices, comprises the sending of a drive signal to a piston pump to draw a breath sample into a sensing chamber, the pump being connected to the sensing chamber. The operational status of the pump is monitored by monitoring the condition of a switch associated with the pump which is adapted to change state when the pump piston is withdrawn into its pump housing as a proper reaction of the pump to its drive signal and return to its original state when the pump piston is no longer withdrawn. The state condition of the of the switch is used to confirm proper pump operation in drawing the breath sample into the chamber; if proper pump operation is confirmed, the breath sample can be accepted for further processing and analysis.]]></description>

            <description><![CDATA[In order to functionally test a leak detector (20) that comprises a partial pressure sensor (21), a testing device (30) having a variable volume (33) is connected to the leak detector. Said testing device can be a syringe. By changing the volume (33), the partial pressure of the test gas contained in the ambient air is changed. A test is carried out to check whether the leak detector (20) indicates the change. According to the invention, a vacuum pumping device having mechanical vacuum pumps is not required. The method is suitable for testing vacuum systems that contain a vacuum pumping device that is used in the leak test to generate a required vacuum. The service technician can perform the functional test of the leak detector (20) separately from the system and the vacuum pumping device.]]></description>
