A method and apparatus for executing an application are provided. The method of executing an application may include: measuring internal air pressure in an electronic device by using a barometer; receiving a user input of applying a force to an external surface of the electronic device by using the barometer, and detecting a value of variation of the internal air pressure, the variation occurring due to the force; and performing a preset operation of the electronic device based on the detected value of the variation of the internal air pressure.

A technique and device (12) may be utilized to determine a characteristic of a crystallographic texture of a sample (10) based on a detected ultrasonic waveform. The device may be configured to receive ultrasonic waveform data representative of a reflected ultrasonic waveform that propagated through a sample from an ultrasonic detector (14). The device may select a portion of the ultrasonic waveform data and apply a Fast Fourier Transform to the portion of the ultrasonic waveform data to transform the portion from a time domain to a frequency domain. The device then may identify a dominant frequency (98) of the portion in the frequency domain and determine a characteristic of a crystallographic texture for the portion based on the dominant frequency of the portion.

A method and a system includes controlling and monitoring the gas pressure in a nuclear fuel rod during filling of the fuel rod with a gas, and subsequent sealing of the fuel rod. The system includes a control unit and a length measuring system, which control unit is communicatively connected to the length measuring system. The length measuring system is configured to monitor the length of the fuel rod, and the control unit is configured to receive measurements from the length measuring system and to determine the gas pressure inside the fuel rod on the basis of variations of the length of the fuel rod. The method includes positioning an open first end of the fuel rod inside a pressure chamber, allowing gas to enter the fuel rod; pressurizing the gas in the pressure chamber at a first pressure level; closing the fuel rod; and sealing the fuel rod.

An apparatus senses properties of a fluid. The apparatus has a pipe section, a valve, and an instrument. The pipe section has an envelope, through which a flow of the fluid is coupled between a tank of an electrical power device and a cooling device. The envelope is disposed about a longitudinal axis, and has a penetration disposed laterally, relative to the longitudinal axis. The valve is disposed within the one or more penetrations and has a closed position and an open position. The instrument is operable for the sensing of the fluid properties, and has a probe disposed in contact with the fluid through the valve in the open position.

A pressure sensing device is configured for measuring water pressure in a soil medium, and includes a sensor housing and a pressure sensor. The sensor housing is adapted with a sensor cavity delimited by an enveloping surface. The sensor housing is provided with a selective passage for water between an outer surface of the sensor housing and the sensor cavity. The pressure sensor is arranged within the sensor cavity for measurement of a water pressure within the sensor cavity. The pressure sensing device includes an antimicrobial substance for preventing microbial gas production in the sensor cavity.

A relay device and a pressure detection device are provided that are configured to eliminate the necessity of calibrating an output value from a pressure sensor in the pressure detection device even when a mold is replaced. A relay device for a pressure detection device provided with a pressure sensor (S1 to Sn) configured to detect an inner pressure in a cavity (CT) of a mold of an injection molding machine is provided. The relay device is integrally fixed to the mold. The relay device includes a storage configured to store specific information of the pressure sensor (S1 to Sn) provided to the mold to detect the inner pressure of the cavity (CT), the cavity (CT) being defined between a fixed-side mold and a movable-side mold of the mold.

A vibration data collection system performs an integration or differentiation process on incoming digitized vibration data in real time. The system uses a digital Infinite Impulse Response (IIR) filter running at the input data rate to provide the integration or differentiation function. With this approach, the system reduces hardware complexity and data storage requirements. Also, the system provides the ability to directly integrate or differentiate stored time waveforms without resorting to FFT processing methods.

An automatic water sampler is disclosed. The automatic water sampler of the present invention comprises: a driving unit operated according to the pressure measured by a pressure sensor; a driving magnet approaching a driven magnet according to the operation of the driving unit; and a first wire unlocked by a control rod according to the movement of the driven magnet. The present invention can provide an automatic water sampler, which improves inaccuracy due to conventional interference of an ocean current, flow velocity, and the like, and manual water sampling by depth by automatically sampling water at the correct depth recognized through a pressure sensor, thereby enabling reliability and accuracy of a sample to be ensured and sampling expenses to be remarkably reduced.
