A method for the measurement of the speed of sound in a gas suitable for the determination of gas characteristics, especially the composition of the gas, the temperature and/or the humidity of the gas, and a speed of sound based gas sensor arrangement adapted to measure that gas characteristics comprising sound sending means and sound receiving means and signal processing unit. A sound sender is used as sound sender and a first sound receiver and a second sound receiver as sound receiving means, all three of them being arranged such that the travel distance of the sound provided by the sender to the first receiver is different from the travel distance of the sound provided by the sender to the second receiver. Further the arrangement includes the signal processing means connected with the sender and the receivers which operate the sender and determine gas characteristics, especially the composition of the gas, the temperature and/or the humidity of the gas, from the different signals provided by the first and the second receiver.

A control body is coupled or coupleable with a cartridge that is equipped with a heating element and contains an aerosol precursor composition, the control body and cartridge forming an aerosol delivery device. The control body includes a control component to control the heating element to activate and vaporize components of the aerosol precursor composition. The control body also includes a gas sensor configured to detect a presence of gas in an environment of the control body, and the gas sensor or control component are further configured to control operation of at least one functional element of the aerosol delivery device in response to the presence of gas so detected.

An interlock data collection and calibration system has a device computer, a gas delivery system, and a data port. The device computer has a computer processor and a computer memory. The gas delivery system delivers a gas sample to an ignition interlock device. The data port is operably connected with the device computer for enabling sample data from the ignition interlock device to be transmitted to the device computer. A calibration program operably installed on the computer memory receives the sample data, calibrates the ignition interlock device, and generates confirmation data, which is stored in a local database.

A gas sensor includes a sensing element having an electrode pad a metal terminal, and a separator that has insertion holes in which the metal terminal is held. The metal terminal includes a main body and an elastic portion that is integrally connected to the main body and is elastically connected to the electrode pad at a predetermined contact point. The main body includes a front-end-side restricting portion and a rear-end-side restricting portion that restrict the movement of the main body by contacting wall surfaces of the insertion hole when the main body moves in a direction intersecting the direction of an axial line. The contact point is located between the front-end-side restricting portion and the rear-end-side restricting portion in the direction of the axial line. The front-end-side restricting portion and the rear-end-side restricting portion are connected to each other so that a flat board portion is interposed therebetween.

A metal terminal includes a front-side terminal member and a rear-side terminal member. The front-side terminal member includes a female connection portion, and the rear-side terminal member includes a male connection portion. The female connection portion has an insertion port in which the male connection portion is inserted. The insertion port is formed in a shape that prevents the insertion port and the male connection portion from coming into contact with each other when the male connection portion is inserted therein. The female connection portion includes a terminal contact portion which brings the male connection portion and the female connection portion into contact with each other by pressing the male connection portion toward the female connection portion inside the female connection portion.

A workpiece inspection device 1 includes a table (3), image capturing unit fixing part (7), first light projection unit (4), second light projection unit (5), linear movement mechanism (8), turning mechanism (9), quality determination unit (10), and control unit (11). The control unit (11) performs first image capturing step of causing first light projection unit (4) to project light and causing image capturing unit (6) to capture image, detailed inspection portion-determination step of setting, portion of workpiece (2) determined to require detailed inspection based on image captured in the first image capturing step, second image capturing step of causing second light projection unit (5) to project light onto the workpiece (2) and causing image capturing unit (6) to capture image of the detailed inspection-requiring portion, and quality determination step of determining quality of the detailed inspection-requiring portion based on image captured in the second image capturing step.

Method for monitoring for partial discharges in an electrical installation comprising at least one electrical cubicle, the electrical cubicle comprising at least one item of medium-voltage or high-voltage electrical equipment.

The present disclosure relates to a conjugated quantum dot nanoparticles, to methods of making such conjugated quantum dot nanoparticles, and to methods of detecting DNA methylation using such conjugated quantum dot nanoparticles.

An anti-copy electronic device contains: a wireless signal controller having a sensor, and the wireless signal controller and the sensor are accommodated in a casing. The sensor has humidity detection, pressure detection, lights detection, color temperature detection, ultraviolet (UV) detection, and special gases detection in an interior space of the casing. After the casing is removed, the sensor detects a change of humidity, pressure, lights, color temperature, ultraviolet (UV), and special gases in the interior space and sends an indication signal to the wireless signal controller so that the wireless signal controller destroys a password setting program of the wireless signal controller, thus avoiding copy of the password setting program.

A gas detection apparatus and method for measuring humidity using an electrochemical gas sensor. The gas detection apparatus comprises an electrolyte-based electrochemical gas sensor and a controller configured to measure the average humidity value within an ambient environment over a period of time. The average ambient humidity value over the period of time is determined based on the average rate of change over the period of time of the electrolyte concentration within the electrolyte gas sensor of the gas detection apparatus over the period and the average temperature in the ambient environment over the period of time. The gas sensing apparatus may be configured to communicate the average ambient humidity value within the ambient environment to a second electrochemical gas sensor or a second gas detection apparatus within the same ambient environment.
