The present invention provides a measurement method, a measurement device, and a program capable of non-destructively measuring a volume of a drug in each needle-shaped recess of a mold with high accuracy. In a measurement method according to a preferred aspect of the present invention, a reference surface height that is a height between a reference surface determined in advance with respect to a first surface on the side on which a drug is filled in a mold or a second surface opposite to the first surface, and the second surface is acquired. A first detection result obtained by detecting, for each needle-shaped recess, a measurement wave emitted from a drug surface that is a surface of the drug according to incidence of the measurement wave on the drug in the needle-shaped recess is acquired. A first height between the reference surface and the drug surface is detected for each needle-shaped recess on the basis of the first detection result. A second height from the second surface to the drug surface is detected for each needle-shaped recess from the reference surface height and the first height of each needle-shaped recess. A volume of the drug in the needle-shaped recess is calculated for each needle-shaped recess on the basis of the second height of each needle-shaped recess and a known shape of the needle-shaped recess.

The invention provides a supply unit (10, 20) for liquid medical oxygen, the supply unit (10, 20) including a reservoir (11, 21) adapted to be filled with the liquid medical oxygen, at least one dispensing valve (13, 19, 23) in fluid communication with the reservoir (11, 21) and operable by a user of the supply unit (10, 20), and an overpressure valve (14, 24) in fluid communication with the reservoir (11, 21) and adapted to open in order to vent the reservoir (11, 21) when a pressure in the reservoir (11, 21) exceeds a given value. The mobile supply unit (10, 20) includes estimating means adapted to provide a value corresponding to an amount of the liquid medical oxygen spent from the reservoir (11, 21) since an initial timepoint at least on the basis of a value corresponding to an initial amount of the liquid medical oxygen in the reservoir (11, 21) at the initial timepoint, a value corresponding to one or more valve settings of the dispensing valve or valves (13, 19, 23) since the initial timepoint, and a value corresponding to one or more durations during which the overpressure valve (14, 24) was open in order to vent the reservoir (11, 21) since the initial timepoint. A corresponding method is also part of the present invention.

A method can include illuminating an interior of a fuel tank (12) with one or more light pulses, and receiving reflected returns of the one or more light pulses at a light sensor array. The method can further include producing, by a processing device, three-dimensional image data of the interior of the fuel tank based on the received reflected returns (124), producing, by the processing device, a fuel measurement value representing an amount of fuel contained in the fuel tank based on the three-dimensional image data (126), and outputting, by the processing device, an indication of the fuel measurement value (128).
摘要:
The invention concerns a system for determining the charge level of a means for storing latent heat energy, said storage means comprising a reservoir partially filled with a phase change material of which the phase change is accompanied by a volume variation with a heat exchanger embedded in said material, said storage means being in a completely discharged state when the phase change material is substantially totally in a first state and in a completely charged state when the phase change material is substantially totally in a second state, characterised in that the system comprises: - a measurement fluid (4) intended to be poured into the reservoir (1) of the storage means, - means (5) for measuring the height of the measurement fluid in the reservoir, and - means for calculating the charge level of the storage means at a determined time in the operation of same, depending on the difference between the height of the fluid present in the reservoir when the storage means is completely discharged and the height of the liquid at said determined time.
摘要:
Electrodes are integrated into a container design for fluid level detection in the container. The electrodes have a conductive surface, and an adhesive backing may be attached opposite the conductive surface to secure the electrodes to the container. Electrical contact to each conducting surface is made to a detection circuit to obtain a fluid level. A radio-frequency identification (RFID) tag may be incorporated onto the container along with the level detection circuit to record the container history, such as last used time event, net evaporation during storage, re-suspension performance after storage, number of agitation cycles, instrument serial number, date opened/accessed, and other desirable information.
