A posture calculation device of working machinery includes: a measuring device configured to detect an angle speed and acceleration; a posture angle calculation unit configured to obtain a posture angle of the working machinery from the detected angle speed and the detected acceleration; a first complementary filter to which a first cutoff frequency is set and configured to decrease a noise included in the obtained posture angle to output a first posture angle; a second complementary filter to which a second cutoff frequency different from the first cutoff frequency is set and configured to decrease a noise included in the obtained posture angle to output a second posture angle; and a switching unit configured to switch between the first posture angle and the second posture angle to output the first posture angle or the second posture angle according to a state of the measuring device.

A method for automatically calibrating a rocker-type sensor module having a position or acceleration sensor involves measuring a position of the sensor module as an angle relative to a fixed spatial direction, and outputting an output signal that depends on whether the measured angle is less than or greater than a switching angle. The output signal is set to a first output value if the measured angle exceeds the switching angle. The switching angle is set to a value corresponding to the measured angle minus an “off” free pivot angle, as long as the value of the measured angle continues to increase. The output signal is set to a second output value if the measured angle falls below the switching angle. The switching angle is set to a value corresponding to the measured angle plus an “on” free pivot angle, as long as the value of the measured angle continues to fall.

A structure sensor device monitors physical properties within a body of concrete, rock, soil or other structure. The structure sensor device can be embedded inside the body of the structure in use. The structure sensor device includes: a sealed housing; sensors for measuring physical properties within the body of structure, such as a temperature sensor and a moisture sensor; and a wireless transceiver for wirelessly communicating with a gateway device located outside of the body of structure. The wireless transceiver is configured for wirelessly communicating at frequencies of less than 1 GHz. There is a controller configured to obtain sensor data from the sensors, generate monitoring data using at least some of the sensor data, and cause the monitoring data to be transmitted to the gateway device using the wireless transceiver, at predetermined intervals.

A surveying system including a surveying device and a terminal device for assisting in placement of a staking tool. The surveying system further includes: a design information acquisition unit for acquiring design information including a designed slope; a surveying information acquisition unit for transmitting surveying information to a terminal device; a current state estimation unit for calculating an estimated altitude of a current ground in accordance with the surveying information; an intersection calculation unit for calculating a coordinate of an intersection between the current ground and the designed slope based on the estimated altitude of the current ground and the design information; a stake shape determination unit for determining a shape of a stake to be placed; and a stake shape information unit for causing the terminal device to inform of the shape of the stake determined by the stake shape determination unit.

A method of estimating a location of a user terminal is provided. It is based on a difference between a true north and a magnetic north that may estimate a location of a user terminal on a magnetic field map based on a difference between a true north and a magnetic north corresponding to each location of the magnetic field map, and the user terminal thereof.

Winch (304) has a load bearing tape (305) to advance into a borehole (307). Hole depth can be determined by subtracting a sensed height (310) above ground surface (311) from total depth (312) measured. Can include a height above ground sensor (314) and a tape distance measurer (316). Depth of water or watery mud or muddy water (320) can be sensed, such as by a pressure sensor (326) on a weight or in a sensor device at or near the tape leading end. A heater (309) can warm the tape. A cover or housing (313) can be provided for the winch or spool. The tape can include wires or fibre optics (336) embedded in or applied to a surface of the tape (305) and/or apertures or embedded or surface applied markers/indicators (338) along a length thereof e.g. for reading by an optical or magnetic sensor.

A system and method are disclosed in the field of preparing a catheter for use in a patient, in particular a catheter of an intravascular blood pump, more specifically for properly purging and de-airing the catheter. The catheter comprises an elongate tubular portion and a connected device. The elongate tubular portion is configured to be inserted into a patient's blood vessel and defines a lumen. The connected device is connected to the elongate tubular portion and has a cavity, which may accommodate a drive unit of the blood pump, and which is in fluid communication with the lumen of the elongate tubular portion. In order to securely de-air the system, a sensor, such as an accelerometer, for detecting an orientation of the connected device is provided, and a user may be guided to correct the orientation of the connected device for proper purging.

Provided are: an inclination angle calculating unit for calculating, when having determined that a vehicle is stationary by referring to vehicle information indicating a traveling state of the vehicle, an inclination angle of the vehicle during a stationary period using inclination angle information indicating an inclination angle of the vehicle and determining a vehicle inclination angle during the stationary period from the calculated inclination angle of the vehicle; and a correction determination processing unit for determining whether an absolute value of a difference between the determined vehicle inclination angle and a reference angle determined previously by the inclination angle calculating unit is less than a first threshold value (threshold value α) and, if the absolute value of the difference is less than the first threshold value (threshold value α), performing a correction to rewrite the vehicle inclination angle to the reference angle.
