Queclink GV300 is a compact machine designed for hid set up within the vehicle. There are both inner and exterior GPS antennas: in different words, iTagPro technology exterior antenna is elective. The device is embedded with rechargeable backup battery. Three LED indicators assist through the set up and diagnostic. Queclink GV300 will not be waterproof. Thanks to GNSS chip from ublox and useful firmware Queclink GV300 helps: multi-system navigation (GPS and GLONASS), Assisted GPS (A-GPS) expertise and Cell ID based location. The overall sensitivity is adequate (if vital you may join an external GPS antenna). Together with adjustable monitoring modes all of those assure reliable and correct GPS monitoring. There are number of inputs in GV300, together with analog ones, which allow to connect a number of vehicle sensors of various varieties. To control external equipment a couple of outputs is used. One serial interface (type RS232) lets connect, on user’s alternative, digital fuel level sensor, camera, PND (Garmin protocol is supported) or external CAN reader. As a GPS tracker manufacturer Queclink is well-known for its purposeful units with complete firmware, and GV300 will not be the exception. The firmware allows to configure a number of options (including remote management over GPRS), iTagPro support detect a variety of events, learn data from CAN bus and iTagPro smart tracker digital fuel degree sensors, use Garmin-compatible PND, monitor driving behaviour. The firmware of Queclink GV300 could be up to date OTA (Over-the-Air). There is only one RS232 serial interface, which is usually a limitation if you need to attach a number of digital gadgets, i.e. two gas sensors or fuel sensor and digital camera. For these circumstances RS485 interface could be higher, but there is no such an interface.

The outcomes obtained in laboratory checks, using scintillator bars learn by silicon photomultipliers are reported. The current strategy is the first step for designing a precision tracking system to be placed inside a free magnetized quantity for the charge identification of low vitality crossing particles. The devised system is demonstrated ready to offer a spatial resolution better than 2 mm. Scintillators, iTagPro locator Photon Solid State detector, particle monitoring devices. Among the deliberate actions was the development of a light spectrometer seated in a 20-30 m3 magnetized air quantity, iTagPro features the Air Core Magnet (ACM). The whole design needs to be optimised for the dedication of the momentum and cost of muons within the 0.5 - 5 GeV/c range (the mis-identification is required to be lower than 3% at 0.5 GeV/c). 1.5 mm is required contained in the magnetized air volume. On this paper we report the results obtained with a small array of triangular scintillator bars coupled to silicon photomultiplier (SiPM) with wavelength shifter (WLS) fibers.

This bar profile is right here demonstrated able to supply the required spatial decision in reconstructing the place of the crossing particle by profiting of the cost-sharing between adjoining bars readout in analog mode. SiPMs are excellent candidates in replacing normal photomultipliers in lots of experimental conditions. Tests have been performed with laser beam pulses and radioactive source with the intention to characterize the scintillator bar response and SiPM behaviour. Here we briefly present the noticed behaviour of the SiPM used in our checks relating to the main sources of noise and the impact of temperature on its response and linearity. Several fashions and iTagPro reviews packaging have been thought-about. The main supply of noise which limits the SiPM’s single photon decision is the "dark current" fee. It is originated by cost carriers thermally created in the sensitive volume and current within the conduction band and due to this fact it will depend on the temperature. The dependence of the dark present single pixel charge as a perform of the temperature has been investigated using Peltier cells in order to vary and iTagPro support keep the temperature managed.

Dark current charge relies upon additionally on the Vwk as proven in Fig. 3. As a way to have low charges of darkish present the worth of Vbias has been mounted at 1.5 V giving a working voltage Vwk of 29 V. It is obvious that, iTagPro support if mandatory, it can be convenient to use a bias voltage regulator iTagPro support which automatically compensates for temperature variations. Not always the pixels of the SiPM work independently from one another. Photoelectrons (p.e.) can migrate from the hit pixel to a different not directly fired by a photon. Optical cross-speak between pixels results in a non-Poissonian behaviour of the distribution of fired pixels. An estimate of the optical cross talk chance could be obtained by the ratio double-to-single pulse rate as a function of the temperature. The likelihood depends weakly on the temperature and the measured degree of cross-discuss (15-16%) is compatible with the one reported in the datasheet. SiPM response once its basic parameters and cells configuration are given.
