A precise optical technique for measuring electronic transport properties in semiconductors is disclosed. Using tightly focused laser beams in a photo-modulated reflectance system, the modulated reflectance signal is measured as a function of the longitudinal (Z) displacement of the sample from focus. The modulated component of the reflected probe beam is a Gaussian beam with its profile determined by the focal parameters and the complex diffusion length. The reflected probe beam is collected and input to the detector, thereby integrating over the radial profile of the beam. This results in a simple analytic expression for the Z dependence of the signal in terms of the complex diffusion length. Best fit values for the diffusion length and recombination lifetime are obtained via a nonlinear regression analysis. The output diffusion lengths and recombination lifetimes and their estimated uncertainties may then be used to evaluate various transport properties and their associated uncertainties.

This disclosure relates to optical RF spectrum analysers and methods for analysing an input RF signal. An optical modulator modulates an input RF signal onto a carrier frequency and an optical spectral weight with a spectral weight function modifies the modulated optical signal.

An optical sensor senses the modified optical signal over time and to generates an RF signal over time. A signal recovery module calculates the RF spectrum based on the RF signal over time. Shifting the spectral weight against the carrier frequency over time results in a high spectral resolution even if the spectral weight is relatively broad band. The result is an increased spectral resolution at a reduced price/complexity and increased robustness.

A method of printer operation identifies inkjets to operate in each scanline to eject sneeze drops or, in an alternative approach, identifies the cross-process direction scanlines within a page to be printed by the printer where each inkjet ejects sneeze drops. The methods use a binary grayscale code counter that generates a sequence of binary grayscale code numbers and every other output of the sequence is bit reversed to spread the sneeze drops over the pages of the printer output so the sneeze drops are not perceptible to a human observer.

The invention describes a facility to provide an indication of level in a container of conductive liquid used in an inkjet printer. The facility comprises an array of nested capacitive sensor pads, the outputs of which can be processed to provide a continuous indication of level. The outputs can also be processed to provide an indication of whether the container is mis-aligned on the printer.

The liquid cartridge includes: a front surface facing in an insertion direction intersecting a gravitational direction; a rear surface spaced apart from the front surface in the insertion direction; an upper surface facing upward; a liquid supply portion disposed at the front surface; an electrical interface disposed at the upper surface; and a movable member including a detection portion. The movable member is movable between a first position and a second position. The movable member at the second position is positioned upstream in the insertion direction relative to the electrical interface. The movable member at the first position has a portion whose widthwise position is coincident with the electrical interface in a widthwise direction orthogonal to the insertion direction and the gravitational direction. The portion of the movable member at the first position is located downstream in the insertion direction or upward relative to the electrical interface.

A liquid discharge apparatus includes a liquid discharge head, a scanning device, a conveyance device, a reading device, control circuitry, and a detecting device. The liquid discharge head is configured to discharge liquid to a target object. The scanning device is configured to move the liquid discharge head in a main scanning direction. The conveyance device is configured to convey the target object in a direction perpendicular to the main scanning direction. The reading device is disposed at a predetermined position with respect to the liquid discharge head. The control circuitry is configured to change a detection pattern image for detecting a defective nozzle, in accordance with a feed amount of the target object in the sub-scanning direction. The detecting device is configured to identify a nozzle corresponding to a defective portion of the detection pattern image read by the reading device.

In a method for controlling an irradiation system for use in an apparatus for producing a three-dimensional work piece, a first and a second irradiation area as well as an overlap area arranged between the first and the second irradiation area are defined on a surface of a carrier adapted to receive layers of a raw material powder to be irradiated with electromagnetic or particle radiation emitted by the irradiation system. A first irradiation unit of the irradiation system is assigned to the first irradiation area and the overlap area, and a second irradiation unit of the irradiation system is assigned to the second irradiation area and the overlap area. At least one of the first irradiation area, the second irradiation area and the overlap area is defined in dependence on a geometry of the three-dimensional work piece to be produced.
