Microfluidic cartridge with parallel pneumatic interface plate

A microfluidic cartridge for placement onto a parallel pneumatic interface plate of a pneumatic instrument is provided. The cartridge includes a three dimensional fluid channel, in which a fluid is to be transported, a flexible membrane that spans a plane and is part of an outer surface of the cartridge. The three dimensional fluid channel is spatially defined in three dimensions by internal walls of the cartridge and by the flexible membrane. The flexible membrane is in a ground state, when no pressure or vacuum is applied to the flexible membrane. However, the flexible membrane is pneumatically deflectable from the ground state perpendicular to the plane of the flexible membrane in two directions when the cartridge is placed onto the parallel pneumatic interface plate.

Positive displacement pump

This invention relates to a positive displacement pump which allows a liquid additive (such as liquid fertilizer) to be introduced into another liquid stream (such as water) and to be mixed in a constant proportion. One end of the pump can be connected to a faucet and the other end to a typical garden hose or other device. Water enters the pump through a faucet and is redirected (bent) by an upper stator which allows the water to rotate turbine vanes. The turbine is rotatably connected to a cam and the rotation of the cam moves pistons which allows liquid fertilizer to be drawn in from its reservoir. The liquid fertilizer flows through a tube and into one of two pistons. Then, the liquid fertilizer is dispelled through one of the exit tubes through the pumping action of the pistons. The water which was used to turn the turbine then combines with the liquid fertilizer as it comes out of the exit tubes and a water / fertilizer mixture is created.

System for controlling the operation of at least one aircraft engine

A system for supervising the speed of at least one engine of an aircraft includes three independent information sources determining first, second and third values for an aerodynamic parameter of the aircraft and precision information indicating the precision of these values. A control unit acts on the operation of the engine, and a sensor measures a fourth value for the parameter. An arithmetic unit selects a control value by using the first, second, third and fourth values of the aerodynamic parameter and the precision information and uses the control value to determine a control sequence for the control unit. An information transmission network, to which the three independent information sources and the arithmetic unit are connected, permits a transmission of information between the sources of information and the arithmetic unit.

Confocal holographic optical storage with non-overlapping records

The present invention relates to a method and a system for the storage of data in the form of volume holograms which do not mutually overlap. The storage medium consists of a light-sensitive materail in the form of a plate of thickness D, in which a single hologram is essentially shaped as a cylinder with the minimal possible cross-section. The signal light beam is modulated with data and directed onto the plate-shaped storage material by means of a lens or a convenient optical system, illuminating an area of said material which, for a given amount of data, is the smallest possible. To record a hologram, a reference light beam is used, incident upon the storage material either from the same direction as the signal beam, or opposite thereto. In contradistinction to prior-art solutions, the inventive reference light beam used for recording illuminates, in the most favorable case, the smallest possible volume of the storage material. The holgoram is only written in the portion where the signal and the reference beams overlap, so its volume is equal to the volume illuminated by the reference beam.

Signal DC offset correction method and device

A method and a device for estimating the DC offset portion of a signal, especially of a signal containing parts with sinusoidal shape, for example a signal which results from demodulation of a frequency modulated receive signal. A method is presented for correcting the direct current offset portion (DC offset) of a first signal which includes phase shifting the first signal for obtaining a second signal and comparing the first signal and the second signal with an estimated DC offset. The estimated DC offset is adjusted if the result of the comparison is that the first signal and the second signal are on different sides of the estimated DC offset and the estimated DC offset remains constant as long as the result of the comparison is that the first signal and the second signal are on the same side of the estimated DC offset.

Device for inducing nucleation

Described is a device for inducing crystal nucleation in a crystalliser. The device comprises a vessel for fluid and a surface abrader, wherein the surface abrader is configured to abrade a surface within the vessel to induce crystal nucleation. The friction of the abrader against the surface within the vessel creates nano-sized particulates which induce crystal nucleation. Crystal growth can then take place in the crystalliser. Also described is a crystallisation apparatus comprising the device and a crystallisation process using the device or similar. The device is significantly cheaper and more reliable than known ultrasound devices and facilitates the separation of crystal nucleation and crystal growth. The device also enables the avoidance of the use of seeding as a source of secondary nucleation.
