Technology and Design Principles The core of the proof mass or seismic mass of InnaLabs® pendulous accelerometers is a high purity fused quartz disc structure (the flapper) connected to a rigid outer frame by two thin hinges. >2 kHz typical).
The invention involves the monitoring of a biological parameter through a compact analyzer. The preferred apparatus is a spectrometer based system that is attached continuously or semi-continuously to a human subject and collects spectral measurements that are used to determine a biological parameter in the sampled tissue.
The technology seems to be workable, but its widespread use, however, is limited by the lack of commercial viability and potential risks due to acute CO poisoning (United
2017-3-22 · Bed material agglomeration was studied experimentally in a fluidized-bed biomass coustor. Four biomass fuels, four bed materials, three bed additives, and three NOx additives were tested in a temperature range of 670−870 °C and at two pressure levels of 1.0 and 1.5 MPa.
2018-11-21 · An inertial navigation system (INS) is a navigation aid that uses a computer, motion sensors (accelerometers), rotation sensors , and occasionally magnetic sensors (magnetometers) to continuously calculate by dead reckoning the position, the orientation, and the velocity (direction and speed of movement) of a moving object without the need for
2018-11-25 · A crystal oscillator is an electronic oscillator circuit that uses a piezoelectric resonator, a crystal, as its frequency-determining element. Crystal is the common term used in electronics for the frequency-determining component, a wafer of quartz crystal or ceramic with electrodes connected to it. A more accurate term for it is piezoelectric resonator.
There are stringent requirements for highly accurate measurement of the parameters of quartz pendulous reeds (QRP) in civilian fields and national defense technology.
Processing Technology of Quartz Pendulous Reed by Chemical Etching "Study on Dynamic Performance of a Flying Car Body Frame Based on ANSYS", Applied Mechanics and Materials, Vols. 602-605, pp. 163-166, 2014 It not only provides the useful date for acoustic analysis of planetary reducer, but also provides theory basis for avoiding
2018-6-21 · The major ash-related problem encountered in fluidized beds is bed agglomeration, which, in the worst case, may result in total defluidization of the bed and unscheduled downtime.
2018-11-29 · The principle of quartz chemical etching process is introduced, and a process of quartz pendulous reed chemical etching technology experiment is
