摘要： An automatic guided vehicles (AGV) can include: motors, wheels, motor controllers, and batteries coupled to an elongated frame. The two wheels can be mounted on opposite sides of the elongated frame. The wheels can be coupled to motors which can be controlled by motor controllers. The motors and motor controllers can be attached to the frame. The center of gravity can be lower than the axis of rotation of the wheels so that the AGV will passively rotated into an upright position. A connector flange can be mounted on top of a payload holder column mounted to a center portion of the AGV frame. Objects can be mounted on or towed by the connector flange.

摘要： A device configured to determine a rotation angle with respect to a proceeding direction includes an accelerometer configured to obtain acceleration information related to movements of the device; a storage unit configured to store the acceleration information; and a controller configured to transform coordinates of the acceleration information, filter the acceleration information on the transformed coordinates, and determine the rotation angle of the device with respect to the proceeding direction of the device by using gravitational acceleration information on the transformed coordinates. The gravitational acceleration information is derived by using information about a time point when a vertical acceleration component at the transformed coordinates of the device has a maximum value, from among the acceleration information.

摘要： A method of fuel gauging includes the use of limited physical probes and a number of virtual probes that are mathematically represented despite having no physical representation. Each probe determines the volume of fuel in a particular section of the fuel tank. The calculation method includes using the attitude of the fuel tank to calculate the rotation of each physical probe, using this information to determine the height of the fuel at each physical probe, and extrapolating the physical height information to determine the position of each virtual probe. Once the information on each physical and virtual probe is obtained, a total fuel volume can be calculated.

摘要： A two-wheeled vehicle is provided. The two-wheeled vehicle includes a chassis having a height, a length and a width, in a first wheel rotatably connected to the chassis, the first wheel having a perimeter, a diameter and a geometric center, and the diameter of the first wheel being at least 75% of the height of the chassis, a motor for providing a drive energy to the first wheel, an axle rotated by the motor, a drive gear connected with the axle such that the drive gear rotates with a rotation of the axle, and a plurality of teeth disposed about the first wheel and mechanically engaged with the drive gear at a location closer to the perimeter of the first wheel than to the geometric center of the first wheel.

摘要： A system and method for an aircraft includes a low profile pneumatic sensing system and an acoustic sensing system. The low profile pneumatic sensing system includes a pneumatic sensor positioned to sense first sensed data of an airflow about an exterior of the aircraft and does not extend beyond a boundary layer of the aircraft. The first sensed data is used to determine first air data parameters. The acoustic sensing system is configured to emit acoustic signals about the exterior of the aircraft and sense the acoustic signals as second sensed data. The second sensed data is used to determine second air data parameters.

摘要： A hearing aid device is disclosed. The hearing aid device comprises means to improve, augment and/or protect the hearing capability of a user by receiving acoustic signals from the surroundings of the user, generating corresponding audio signals, possibly modifying the audio signals and providing the possibly modified audio signals as audible signals to at least one of the user's ears. The hearing aid device comprises a sensor member for detecting the movement and/or acceleration and/or orientation (or spatial position) of the hearing aid device. The hearing aid device comprises at least two hearing aid microphones and a control unit for determining the position or a deviation from an intended position of the hearing aid device or hearing aid microphones. The hearing aid device is configured to compensate for a possible dislocation of the hearing aid microphones.

摘要： The present disclosure concerns a method for detecting the tilt of a roof floating on a medium in a tank, wherein a radar level gauge is mounted in a fixed position on the tank and emits signals in the direction of the roof. The method includes: determining and recording the level of the floating roof during a period of time including some filling/emptying cycles of the medium in the tank, detecting and recording the echo amplitudes of the echo signals during said period of time, filtering the echo amplitudes and recording the filtered echo amplitudes, calculating the gradient of the filtered echo amplitudes, calculating a threshold value for a tolerable deviation of the gradient of the filtered echo amplitudes, and generating an alert message that a roof tilting is detected if the deviation of the gradient falls behind the threshold.

摘要： Provided are non-exposure supplied fuel quantity testing device and method of a vehicle-mounted type, and more particularly, a device formed in a trunk of a vehicle without being exposed to test whether or not the ordered fuel quantity is supplied at the time of supplying fuel. Since the device is formed so as not to be exposed, it is disable to perform an artificial tampering of a lubricator, and since the device is mounted in the trunk, it is enable to measure whether or not the ordered fuel is supplied accurately at the same time as supplying fuel. The present invention relates to a testing method using the testing device.

摘要： A device for measuring a position of a panel of an overhead garage door is described. The device has an accelerometer, an atmospheric pressure sensor, and a processor. The accelerometer is attached to the panel and detects a motion or vibration of the panel. The atmospheric pressure sensor triggers a measurement of an ambient atmospheric pressure in response to the detected motion of the panel. A state of the panel is determined based on a combination of the measured ambient atmospheric pressure and the detected motion of the panel.

摘要： A method for measuring a dip angle of oppositely crossly placed paired quartered ring-quartered circle nested polar plates. An annular coplanar capacitance measuring head of a sensor unit consists of four quarter round metal plates and four quarter circular-ring-shaped metal plates, the eight metal plates are coplanar and concentric with one another, and a quarter round metal plate and a quarter circular-ring-shaped metal plate corresponding to the same sector angle form a capacitor. Two annular coplanar capacitance measuring heads are arranged on two round insulating substrates, the two round insulating substrates are used as two bottom surfaces of a cylindrical container, the cylindrical container is transversely arranged, and an insulating liquid equal to ½ volume of the cylindrical container is injected into the cylindrical container in a sealing manner. Potential leads extract potentials of the sixteen metal plates and are connected to an input end of a capacitance measuring unit, and the capacitance measuring unit is connected to a dip measuring unit. When the cylindrical container tilts, the relative positions of the two annular coplanar capacitance measuring heads and the insulating liquid are changed, and a dip angle value can be calculated by measuring the change of a capacitance value. Also disclosed is a device for measuring a dip angle of oppositely crossly placed paired quartered ring-quartered circle nested polar plates.
