A system related to inland farming of seafood products within an environmentally-controlled seafood-farming environment. The seafood-farming environment is preferably established within at least one substantially buried space. The associated apparatus preferably comprises at least one nutrient supplier to supply adequate nutrients to at least one aqueous medium supporting the farming of the seafood, and at least one waste remover to remove unwanted waste from the aqueous medium. Surface crops are grown above and around the seafood-farming environment to maximize production within the farming site. A kit and methods of implementation are also discussed.

A plurality of probes such as a signal probe (3) and a power supply probe (4) are provided into a metal block (1) so as to penetrate. Each of the probes has a movable pin (11). A tip of the movable pin is projecting from one surface of the metal block (1). And a projection length of the tip is variable. A DUT 20 is pressed onto the surface of the metal block (1) to contact between electrode terminals (21 to 24) and tips of the probes to test characteristics of the DUT. At least one of the probes is capacity loaded probe having a capacitor by providing a dielectric layer and a metal film to peripheral of the probe. As a result, noise can be removed reliably. Additionally, when the capacity loaded probe is used as the power supply probe, a voltage drop is reduced at the power supply terminal in a case of change of the output.

A detection device for detecting a marker in a liquid, preferably a fuel, comprising:a reaction chamber 5, provided with a de-dopable conductive polymer 6 building a path between two conductive pads 10 connected to a resistivity measurement device,wherein the de-dopable conductive polymer 6 is able to be de-doped by a chemical reaction with the marker, changing its resistivity.

A self-healing video surveillance system is described. The self-healing video surveillance system includes one or more surveillance cameras that are configured to store configuration data of a network video recorder in operable communication with the surveillance cameras. The network video recorder includes configuration data, and a module configured to store the configuration data on the surveillance cameras and / or retrieve configuration data stored on the surveillance cameras. A new network video recorder introduced into the network retrieves the stored configuration data to self-configure with minimal or no human interaction. In embodiments, configuration data is distributed among a plurality of surveillance cameras, and may be stored in encrypted format.

An image processing apparatus for preventing unauthorized uses of image data by allowing the addition of a specific image in a black-and-white mode even when it is set that a specific image is added in a color mode. When a document is copied, a control section determines whether the apparatus is in a color mode or a black-and-white mode. When in a black-and-white mode, an adding condition determining section reads a set security level and a differential value and determines a security level lower than the one in a color mode. Based on the security level in a black-and-white mode, an adding condition of a specific image is determined. The specific image adding section adds a specific image different from the one in a color mode based on the adding condition. A black-and-white image added with the specific image is printed.

A charging device and a control method thereof are provided. The charging device includes an adapter, an energy storage unit and a charging module. The adapter provides an adapter current. The charging module receives the adapter current and provides a first charging current to charge the energy storage unit, or an output current to charge an electronic device. When the input current is larger than a first preset current and the first charging current is equal to or less than a third preset current, the charging module operates in a boost mode, such that the energy storage unit provides a second charging current to the charging module. When the second charging current is larger than the third preset current, the charging module enters a buck mode such that the energy storage unit is charged by the first charging current.

Sealed connection device between a first and a second closed space, closed off by doors, first part (A) for securing the first and second flanges to one another, second part for securing the second door and the first door in a sealed manner, part for detaching the second door from the second flange, third part for releasing the first door in relation to the first flange (18), fourth part for opening a passage between the first and the second closed space, and part for controlling the first, second, third and fourth parts allowing for the sealed connection without rotation of one of the closed spaces, the device also comprising a device for maintaining by snap fitting (34) for the second closed space in relation to the first closed space prior to the securing by the first part for securing.

A method for fail-safe monitoring of the speed of a drive that includes at least a converter, a motor, and a rotational speed sensor, wherein a target rotational speed is specified to the drive and an actual rotational speed is sensed via the sensor, where a substitute rotational speed is calculated and three plausibility checks are performed in a safety program of a safety CPU, the substitute rotational speed being determinable, for example, from the initial frequency of a converter or from the quotient of EMF and magnetic flux, in each case two of the following three values being checked: target rotational speed, actual rotational speed and substitute rotational speed to achieve a high safety integrity level while avoiding disadvantages of conventional solutions, and because the calculated substitute rotational speed is independent of the sensor, even sensor errors that are difficult or impossible to detect via conventional solutions become detectable.
