摘要: Methods, systems, and devices for acoustic structural reflection interference mitigation are provided in accordance with various embodiments. For example, some embodiments may provide for structural reflection interference mitigation for compact three-dimensional ultrasonic anemometers. Some embodiments include a method that may include transmitting a first acoustic signal from a first acoustic transmitter. At least a first portion of the first acoustic signal from the first acoustic transmitter may be hindered from being received at a first acoustic receiver. At least a second portion of the first acoustic signal from the first acoustic transmitter may be received at the first acoustic receiver along an acoustic propagation path. In some embodiments, the first acoustic transmitter may include a wide-beam transmitter. Some embodiments may utilize four wide-beam transducers positioned at apices of a tetrahedron.

摘要: A device serves for determining the speed of a passenger-transporting system. The device includes an arrangement of auxiliary elements and a sensing device. The arrangement of the auxiliary elements rotates, in a manner corresponding to a movement of the passenger-transporting system. The sensing device can sense whether an auxiliary element is, or is not, located at a certain sensing location. The auxiliary elements are of a first configuration type and a second configuration type. The sensing device can sense whether an auxiliary element is of the first configuration type or of the second configuration type. Furthermore, the sensing device can assign an auxiliary element of the first configuration type and an auxiliary element of the second configuration type to one another such that the direction of rotation can be determined from the order in which the auxiliary elements are sensed.

摘要: A toothed target rotationally fixed to a shaft of the engine includes a series of n real teeth, followed by m dummy teeth forming a reference zone. For each tooth k, the period of time separating the latter from the preceding tooth k−1 is measured. A signal exhibits at least one transition in level in a portion of the signal corresponding to the passage of the reference zone. A first and a second product are calculated for at least some of the values of k; the ratio between these two products is calculated; and the direction of rotation of the engine is detected, in case of correspondence of the ratio with a first noteworthy value and with a second noteworthy value which are representative, respectively, of rotation in a normal direction and rotation in a reverse direction.

摘要: At a time that a position detecting device is initiated, an arithmetic processing unit calculates the absolute position of a rotating shaft at the time of initiation, on the basis of first to third analog signals corresponding to first to third angles of rotation, which are detected respectively by first to third rotational angle detectors. During rotation of the rotating shaft, a current position counter detects a current absolute position of the rotating shaft by counting a number of pulses of forward rotation pulses or reverse rotation pulses, corresponding to the first angle of rotation detected by the first rotational angle detector, taking as a standard a total number of pulses corresponding to the absolute position of the rotating shaft at the time of initiation.

摘要: An apparatus and a method provide an output signal indicative of a speed of rotation and/or a direction of movement of a ferromagnetic object having ferromagnetic features and capable of moving. A variety of signal formats of the output signal are described, each of which have pulses at a rate faster than the ferromagnetic features pass by the magnetic field sensor.

摘要: A magnetic sensor may include a first sensing element and a second sensing element. The first sensing element may be capable of sensing a first component of a magnetic field that is non-parallel to an axis formed by an intersection of a first plane and a second plane. The first plane may be a plane in which a tooth wheel rotates, and the second plane may include a first surface of the first sensing element and a second surface of the second sensing element. The first component of the magnetic field may be on the second plane. The second sensing element may be capable of sensing a second component of the magnetic field. The second component of the magnetic field may be on the second plane.

摘要: Wireless transmission of wheel rotation direction is disclosed. A disclosed apparatus includes a tone ring exhibiting a rotational asymmetry and a detector to measure a rotational direction of a wheel of a vehicle based on the rotational asymmetry and to measure a rotational speed of the wheel, where the detector or the tone ring is operatively coupled to the wheel. The disclosed apparatus also includes a wireless transmitter to transmit the rotational direction and the rotational speed to a receiver proximate or within an engine compartment of the vehicle.

摘要: A first counter is incremented when a first rotational speed sensing device detects a falling edge of one of the teeth of a single multi-tooth target wheel, a second counter is incremented when a second rotational speed sensing device detects a falling edge of one of the teeth, and a third counter is incremented when either of the first and second rotational speed sensing devices detects either of a rising edge and a falling edge of one of the teeth. A direction of rotation is determined based upon the third counter and a rotational speed of the rotatable member is determined based upon one of the first and second counters. The rotatable member is indicated to be at zero speed when the rotational speed is less than a threshold speed and the direction of rotation changes between a positive direction and a negative direction.
