Abstract: A method of writing voxels to a substrate using a laser writing system comprises forming a first voxel at a first position in a substrate using a first laser pulse; detecting light emitted or scattered by the substrate as a result of forming the first voxel; determining whether the detected light satisfies a predetermined constraint; and, when the detected light does not satisfy the predetermined constraint, adjusting an amplitude of a second laser pulse. Light emission or scattering from the substrate as a result of forming a voxel is related to the properties of the formed voxel. By monitoring such emission or scattering, it is made possible to compensate for variations in performance of the laser writing system. Also provided herein are a laser writing system and computer program product which implement the method.

Abstract: A method for forming birefringent voxels comprises simultaneously generating a first seed pulse and a first data pulse. The first seed pulse and the first data pulse are spatially-separated laser pulses having different amplitudes. The first seed pulse is focused at a first seed location, and the data pulse is focused at a first data location. The first seed location and the first data location are separated by a predetermined distance along a scan path, with the first seed location being ahead of the first data location. Subsequently, a second seed pulse and a second data pulse are generated, and focused at a second seed location and second data location, respectively. The second seed and data locations are separated by the predetermined distance. The second data location is the same as the first seed location, resulting in formation of a birefringent voxel.

Abstract: Subjective and objective assessment attributes and measurements related to athletes are captured in an athlete assessment database. Attributes can be entered and updated by at least one evaluator in the field to the athlete assessment database using a client/server software application and mobile client devices. Following capture of the assessment attributes to assessment attribute records in the athlete assessment database, at least one ranked listing of the athletes is created based on the captured assessment attribute data, for printing, display or further use. Captured assessment attributes with relation to the athletes in question can be averaged, normalized or otherwise manipulated. A drafting interface could be provided to allow for immediate or streamlined team selection in a league. The method enhances the speed and accuracy of team selection and athlete ranking processes, over current paper based processes.

Abstract: Examples are disclosed that relate to efficiently producing multiple laser beams of a harmonic frequency from a fundamental frequency beam. One example provides a laser system comprising a laser configured to output a fundamental frequency beam, a first harmonic-generation stage, and a second harmonic-generation stage. The first harmonic-generation stage is configured to receive an input of the fundamental frequency beam from the laser, and output from the laser system a first-stage harmonic frequency beam and a first-stage residual fundamental frequency beam. The second harmonic-generation stage is configured to receive an input of the first-stage residual fundamental frequency beam, and to output from the laser system a second-stage harmonic frequency beam.

Abstract: An apparatus comprises perforating guns, bypass, and isolator mechanism. The first gun fires upon receipt of a first pressure signal delivered from a first axial side of the first gun. The second perforating gun is mounted on a second axial side of the first perforating gun, and fires upon receipt of a second pressure signal delivered from the first axial side of the first perforating gun. The bypass extends from the first axial side of the first gun to the second gun for communicating the second pressure signal to the second gun. The isolator mechanism is configurable between a first configuration in which the bypass is isolated from receiving a pressure signal to the second perforating gun, and a second configuration in which the bypass is permitted to receive a pressure signal. The isolator mechanism is reconfigurable from the first to the second configuration after the first gun has fired.

The method comprises acquiring an image of a voxel of the storage medium, applying a first low-pass filter with a first cutoff frequency to the image of the voxel to obtain a first background image, applying a second low-pass filter with a second cutoff frequency to the image of the voxel to obtain a second background image, the second cutoff frequency being different than the first cutoff frequency, determining an enhanced background image from the first background image and the second background image, determining birefringence values for the enhanced background image, determining birefringence values for the image of the voxel, and correcting the birefringence values for the image of the voxel based upon the birefringence values for the enhanced background image.

Abstract: Some examples of the present disclosure relate to a method for washing an annulus that at least partially surrounds a casing in a well. The method comprises locating a tool inside a wellbore casing, and flowing a washing fluid from an injection aperture on the tool and into the annulus via a first casing aperture in the casing. An inflow region of the casing is created having a reduced pressure relative to the annulus, and the method involves flowing the washing fluid from the annulus and into the inflow region of the casing through a second casing aperture in the casing.
