A container for holding a product including a holding means for removably holding a product measuring device adjacent the upper end of the container. The holding means is connected to the container and the measuring device may be replaced in the holding means to secure the measuring device therein during use of the product.

A liquid level detection method includes capturing an image of a liquid surface, a structural surface, and graduation markings provided on the structural surface using an image-capturing device to thereby obtain an initial image. Subsequently, the initial image is processed so as to generate a processed image, and a level reference value of the liquid surface is obtained from the processed image. The level reference value represents a height of the liquid surface in terms of inherent characteristics of the processed image. Lastly, a liquid level of the liquid surface is calculated based on a relative proportional relation among the level reference value, an overall height of the processed image in terms of the inherent characteristics of the processed image, and dimensions of any one of the initial and processed images relative to the graduation markings.

A food chopping or slicing device preferably includes three primary components, including a lid, a blade tray, and a food reservoir. The lid and the food reservoir are pivotally connected to one another, with the blade tray being removably mounted within an upper rim of the reservoir. In some embodiments a reservoir bottom is removable and the device includes orthogonal volumetric markings.

A wireless tank level monitoring system is provided. The system includes a transmitter that is located in close proximity to the storage tank. The transmitter is coupled to a remote-ready tank level gauge, which provides a ratio-metric voltage output proportional to the liquid volume inside the tank. The transmitter periodically monitors the output from the level gauge and transmits the information to a base station located remotely from the storage tank. The base station displays the tank level numerically in percent full, graphically with a bar chart, or both. A conspicuous visual indication is provided by the base station when the tank level drops below a predetermined set point. In battery powered applications, the base station also reads and provides a visual indication of a low battery condition for both the transmitter and base station.

A dispensing utensil 10 comprising: a handle portion 11 having a first end portion and a second end portion and a frangible connection intermediate the first and second end portions; an implement portion 12; a cavity 15 for storing dispensable contents, the cavity 15 defined by a first wall means 13, 14 and a second wall means 19 closing the cavity 15; characterized in that a first portion 20 of the first wall means 13, 14 is openable about a hinge formed by the second wall means 19, thereby allowing the contents to be dispensed.

Methods of characterizing subsurface conditions in a selected geographic region previously associated as a whole with a specific subsurface material characteristic reference profile such as from a USDA-NRCS soil survey. The method includes deploying a sensing tool at selected positions within the geographic region to determine a depth-referenced subsurface material characteristic such as soil type or strata, comparing the determined subsurface material characteristic to the subsurface material characteristic reference profile associated with the geographic region to determine a correlation between the subsurface material characteristic reference profile and the depth-referenced subsurface material characteristic, and then deciding whether to deploy the tool at another position, and at what optimum position to deploy the tool, by considering the correlation.

A test apparatus for the measurement of expansion and / or shrinkage of a cement test sample during curing under pressure and temperature conditions that simulate downhole oil well conditions isolates the test sample from a first fixed volume of incompressible pressurized liquid using a flexible barrier that forms a wall of a first chamber in a pressure vessel assembly. The first chamber is sealed by a movable piston. A second pressurizing medium is contained in a second chamber on the opposite side of the piston, and is in fluid communication with a pump, whereby the piston is pressure-balanced between the first and the second medium. The piston moves in a bore of the vessel assembly in response to changes in the volume of the test sample during curing and the amount of linear movement of the piston is detected by a sensor system that measures, correlates and transmits any change in the position of the piston as a change in the sample volume for display and recording.

Devices and methods for depositing fluids on substrates in patterns of spots, lines, or other features use a nozzle, which is preferably configured similarly to a micropipette, having a piezoelectric crystal or other ultrasonic actuator coupled to one of its sides. The nozzle may be charged via capillary action by dipping it into a well containing the fluid to be deposited, and may then be positioned over a desired area of a substrate, at which point activation of the ultrasonic actuator at ultrasonic frequencies will eject the fluid onto the substrate. The needle may subsequently be dipped into a well of rinsing fluid for cleaning. Spots or lines on the order of 5 micrometers width may be generated, making the invention particularly suitable for use in biological applications such as microarray production and in microelectronics applications such as the printing of organic circuitry.

The present invention provides an improved apparatus for measuring and dispensing powdered products. The apparatus includes a cup portion and a funnel-shaped dispenser. The cup holds the powdered material to be measured is sized to contain a desired volume of the powder when filled to its upper edge. The upper edge of the cup has a flat surface to accommodate leveling of the powdered ingredients. The funnel-shaped dispenser serves as a leveler and aids in accurately dispensing the measured powder into a mixing area. The funnel-shaped dispenser thus defines a flat edge at its receiving opening for engaging the upper edge of the cup.
