The pillar may comprise sidewalls defining a cylindrical circumference of a first diameter. In a particular embodiment, the pillars associated with the plurality of memory cells may define rows and columns of an array. In a further embodiment, a pillar may be spaced by a first distance of magnitude up to the first diameter relative to a neighboring pillar within its row. In an additional further embodiment, the pillar may be spaced by a second distance of a magnitude up to twice the first diameter, relative to a neighboring pillar within its column.

An external jet nozzle mixer (20) includes identically formed lobes (48), equal in number those of the internal mixer (42). External mixer (20) works with internal mixer (42), further to mix the engine internal bypass flow with the internal jet engine core flow, to level the disparate exhaust flow velocities, to reduce the peak velocities from the jet engine core and increase the lower bypass velocities of the engine internal bypass flow, and thereby to reduce noise. The internal lobe contours act as lifting flutes, causing mixing of the primary hot and cold flows before exiting the nozzle. The external lobe contours act as venturi chutes, accelerating the cooler ambient air secondary flow. The lobes thus act collectively as an injector to force the cooler ambient secondary flow into the previously mixed primary flow as it exits the nozzle. Also obtained is an increased thrust efficiency and a consequently decreased fuel consumption and engine emissions.

Positions of a plurality of objects in a space are detected. A position of reflected light of an object passing through an infrared screen is specified by analyzing an image obtained by selectively imaging the infrared rays. When the infrared screen is formed in front the display, reflected light is only caused just in front of the display. When the infrared rays are selectively imaged, a picture displayed with visible light is separated from reflected light in the infrared region, and only the reflected light can be imaged. A position of the reflected light on the display can be specified by a publicly known image analysis technique.

Substrates, methods for making the substrates and methods for using the substrates for mass spectrometry analysis are provided. Methods include coating a conductive substrate having a hydrophilic surface (suitable for mass spectrometric analysis) with an uncharged hydrophobic surface, masking a subset of regions on the hydrophobic surface with an insulator, and applying an oxidizing force to the unmasked regions of the hydrophobic surface to render the unmasked regions hydrophilic.

A second stage external jet nozzle mixer (20) includes identically formed lobes which equal in number the lobes of the first stage internal mixer. The external mixer works with the internal mixer, and furthers the mixing of the jet engine internal bypass flow with the internal jet engine core flow. This mixing levels the disparate flow velocities attendant with the jet engine exhaust, reduces the peak velocities from the jet engine core and increases the lower bypass velocities of the jet engine internal bypass flow. The lobes include complex curvatures that greatly enhance mixing of the gases and ambient cooling air, and thereby reduce noise. At the lobe terminus, the lobe dimensional characteristics may be adjusted to thereby adjust the total terminus area to achieve a match to a jet engine to cause that jet engine to run at a determined RPM and noise level. Noise attenuation may also be adjusted by changing lobe dimensions. Prior existing second stage exhaust jet nozzle mixers may be retrofitted to allow alteration of their total terminus area by employing the disclosed device and method.

A lighting system that includes luminaires (1,2,3,4,5) installed at individual locations (R1-5) in premises, is commissioned by placing auxiliary commissioning devices (6) in the premises at spaced apart locations and forming them into a wireless local network. The auxiliary commissioning devices each include a sensor (13) to detect light from the luminaires, establishing the locations of the auxiliary commissioning devices in relation to the premises, for example by using ranging on the basis of signal strengths of the devices (6) in the local network, and detecting light emitted from the luminaires individually with the sensors (13) of the auxiliary commissioning devices such as to associate the luminaires with individual ones of the commissioning devices.

A rotatable media storage device operates using multiple disk spin-speeds, e.g., a reduced spin-speed and a nominal spin-speed. A disk is spun up to a reduced spin-speed and an initial data transfer is began while the disk spins at the reduced spin-speed, if an amount of work that has been requested is below a threshold. The disk is spun up to a further spin-speed (e.g., a nominal spin-speed), which is greater than the reduced spin-speed, and the initial data transfer is began while the disk spins at the further spin-speed, if the amount of work that has been requested is above the threshold. Alternative embodiments using multiple disk spin-speeds are also provided.

A method for printing corrugated cardboard sheets is effected by transferring the corrugated cardboard sheets while jetting ink droplets from ink jet nozzles onto the corrugated cardboard sheets to form dots thereon. Said method comprises the steps of transferring the corrugated cardboard sheets one by one while at the same time sucking one flat surface of each of the corrugated cardboard sheets, and adjusting the relationship among the velocity at which the corrugated cardboard sheets are transferred, the suction force of the corrugated cardboard sheets, and the distance between the ink jet nozzle and the other corrugated surface of each of the corrugated cardboard sheets in accordance with the configuration of the said other corrugated surface and the desired DPI of dots to be formed on the said other corrugated surface. As a result, the ink droplets are jetted toward the said other corrugated surface to be printed thereon.

A recentering device for a rotor shaft for recentering a rotor shaft relative to an axis X of a stator structure in the event of decoupling caused by excessive imbalance. The shaft, in normal operating conditions, lies on the axis X and is radially supported by a bearing support disposed in a bore of the axis X in the stator structure. The bearing support has an outside diameter smaller than the diameter of the bore, to enable the bearing support to orbit about the axis X in the event of decoupling. The bearing support is connected to the stator structure by radially fusible elements. The recentering device recenters the bearing support after decoupling.

Templates used for a facial recognition process for authentication of a user to use a device may be updated by the device as features of the user change over time. Features of the user may gradually change over time due to changes such as facial hair changes, haircuts, gaining/losing weight, and/or aging. Updating the templates used for the facial recognition process may allow the user to continue being authenticated as features of the user change without the need for additional enrollments of the user.

An electromagnetic moving system comprises a stator, a moving body and a controller. The stator comprises a circuit board with two layers of electrically connected coil windings spaced apart in a series way and made as spirals with center and peripheral points. The spirals of one layer are shifted in respect to the spirals of the adjacent layer along the line connecting the center points thus the center points of the spirals of one layer in transparent view are located between two nearest spirals of the adjacent layer. Each of the spirals of one layer in transparent view at least partially overlaps two nearest spirals of the adjacent layer. The moving body is comprised of one permanent magnet such as to cause interaction with the stator when it is powered, thus creating a force tending to propel the moving body along the line connecting said center points.

Methods and apparatus provide for front-end processing of a first differential output current, whereby a first differential output current is received and a second differential output current having reduced spurious content is produced. Current steering is used to divide, and reassemble, the first differential output current so as to provide an output signal with reduced spurious content. Current steering is implemented by a return-to-zero circuit that is coupled to the terminals of a first differential current output stage. During a first phase, the return-to-zero circuit provides a differential output current equal to the first differential current output. During a second phase, the return-to-zero circuit provides a differential output current equal to zero. The current steering return-to-zero circuit is implemented with MOSFETs or any other suitable electrical circuit element that provides the ability to controllably pass or refrain from passing current.
