In this section, we introduce the main concepts related to this paper and provide basic theories of heading determination using sun sensor, inclinometer
, and local clock.
The dual-axis inclinometer
selected for the experiment (Posital Fraba ACS-060) provides as output the direction sines of the gravity vector (g) with respect to [[??].sub.i] (call the angle X) and [[??].sub.i] (call the angle Y), that is,
Since the new device is a modified version of an existing inclinometer
with an extended arm, we aimed to assess the intra-examiner reliability of the device.
A CX-4C inclinometer
was used to measure the deformation of the pipe-roof in the tunnel exiting portal.
During testing, two types of COFT were used to measure displacement of sliding surface; an inclinometer
monitoring internal movement of the slope mass was compared to COFTs.
Another application was electronic inclinometer
application on a smartphone).
Beyond the load and mix functions and inclinometer
, he adds, the SCT system provides concrete producers:
This is easily measured by the inclinometer
in a turn coordinator or turn-and-bank indicator.
The measurement of rotations was carried out with the patient lying supine on the table, his arm was abducted at 90[degrees], the inclinometer
was settled on the metal plate secured to the back of the wrist thanks to the Velcro.
Concretely, the acceleration data of 3 axes of accelerometer are given behind the abbreviation "ACC", following with a temperature measured by an embedded thermometer; the number behind "BATT" shows the current voltage from the external power supply; "INC" leads a spontaneous data set from the two orthogonal inclinometers
. To ensure the digital accuracy after transmission, the units of the data from the accelerometer, the battery and the inclinometer
are chosen as mm/[s.sup.2],mV and [micro]m/[s.sup.2] .
Designed for use in outdoor applications, the inclinometers
are sealed up to IP68 standards.
