摘要:
A vehicle includes a plurality of water level sensors, for example comprising capacitive or resistive sensors, from the outputs of which can be determined vehicle orientation when wading. In conjunction with a vehicle orientation sensor, the outputs from any one water level sensor permits calculation of water depth at any point on the vehicle body.

A transducer for use in a fluid detector for determining a presence of a fluid within a container, the transducer comprising a piezoelectric element that outputs an ultrasonic signal in response to an input electrical signal, characterized in that said transducer further comprises, a lens with an upper portion, a lower portion, and a focal point, the upper portion including a curved surface with convex side. The piezoelectric element is coupled to the upper portion of the lens so that, when the lens is disposed adjacent an outer surface of a wall of the container such that the lens is intermediate the piezoelectric element and the wall, the lens focuses the ultrasonic signal toward the focal point of the lens and on the inner surface of the wall.

A vehicle (100) comprising a wading information display (1020), a memory and a processor, the memory containing a program configured to run on the processor to calculate the maximum wading depth of the vehicle from the measured suspension travel, and to display the maximum wading depth on the display. The display may also show a dual wading depth, an advisory wading speed, and vehicle inclination.

A method of operating an acoustic pulse echo ranging system is provided. A series of acoustic energy pulses of successively increasing or decreasing burst frequencies are transmitted through a transducer assembly. For each transmitted energy pulse associated echoes are received and converted into an echo function over time. The obtained echo function is stored in a two-dimensional pattern whose first dimension is the burst frequency and whose second dimension is the time. Based upon the two-dimensional pattern a frequency response function is evaluated as a function of echo function values over burst frequency at a selected point of time.

A method for measuring a fill level of a fill substance in a container and for monitoring at least one predetermined fill level (LMIN, LMAX), using a fill level measuring device working according to the travel-time principle, as well as a corresponding fill level measuring device, wherein the monitoring satisfies high safety standards, wherein, in each measuring cycle, transmission signals (S) are sent toward the fill substance and their echo signals (E) are received, the fill level is determined, based on the echo signals (E), in a first evaluation method, and it is determined, based on the echo signals (E), in a second evaluation method independent of the first evaluation method, whether the fill level exceeds or falls beneath the predetermined fill levels (LMIN, LMAX).

A fluid detector for determining a presence of a fluid within a container includes a piezoelectric element that outputs a first ultrasonic signal in response to an input electrical signal and a lens with an upper portion and a lower portion. The piezoelectric element is coupled to the upper portion of the lens so that, when the lens is disposed adjacent the outer surface of the wall such that the lens is intermediate the piezoelectric element and the wall, the lens focuses the first ultrasonic signal toward the wall so that the first ultrasonic signal enters the wall.
摘要:
A device for controlling the filling of a receptacle with liquid by a drink vending machine. The device includes visual marking device for marking the liquid fill level in the receptacle, a device for emitting a signal towards the receptacle, a device for receiving an incident signal and which receives the incident signal returning from the receptacle and a controlling device configured for commanding the stoppage of filling on the basis of a variation of the incident signal. The receiving device includes a series of photoelectric receivers and at least one variable which is a displacement of a light incident signal measured by the receivers.

摘要:
A system for measuring distance in a gas or liquid operating medium has an even number of ultrasonic signal transmitters (12, 14), and a single ultrasonic signal receiver (16). The ultrasonic signal transmitters are adapted to transmit ultrasonic signals to a target (18) in the operating medium. Each of the transmitters and receiver are so spaced apart in a geometrically symmetrical planar array within an acoustically attenuating substrate medium, and each of the transmitted ultrasonic signals are so pulse driven in an acoustically symmetrical relationship, that opposing ultrasonic signals transmitted through the substrate medium by symmetrically opposed transmitters are cancelled at the receiver and a signal for measuring distance to the target is formed at the receiver by combination of the transmitted signals through the operating medium.
