Abstract: A drug delivery system for injecting a medicament includes a housing, a container configured to receive a medicament including a stopper configured to move within the container and a closure, a needle in fluid communication with the container, a spacer configured to be engaged with the stopper, a first plunger, a first spring configured to bias the first plunger in an axial direction, second plunger disposed about the first plunger, a second spring configured to bias the second plunger in an axial direction. The first plunger is configured to move the spacer and the container relative to the housing via the first spring to establish fluid communication between the container and the patient needle, and the second plunger is configured to move the spacer and the stopper relative to the container via the second spring.

Abstract: A method of assisting a user with the discovery of program features is provided. The method includes detecting a selection of a data structure within a user interface, determining a contextual parameter based on the selected data structure, the contextual parameter associated with a modifiable feature of the selected data structure, determining options for generating program code configured to modify the modifiable feature are available based on the contextual parameter and a predefined inferential relationship between the contextual parameter and the modifiable feature of the selected data structure, and prompting the user in the user interface with information indicating that the determined options for generating the program code are accessible in the user interface.

Abstract: A semiconductor substrate includes a first semiconductor layer, a first dielectric layer coupled to the first semiconductor layer, and a second semiconductor layer coupled to the first dielectric layer. The second semiconductor layer includes a base portion substantially aligned with the first dielectric layer and a cantilever portion protruding from an end of the first dielectric layer. The cantilever portion includes a tapered surface tapering from a bottom surface of the second semiconductor layer toward a top surface of the second semiconductor layer.

Abstract: A method for fabricating a cantilever having a device surface, a tapered surface, and an end region includes providing a semiconductor substrate having a first side and a second side opposite to the first side and etching a predetermined portion of the second side to form a plurality of recesses in the second side. Each of the plurality of recesses comprises an etch termination surface. The method also includes anisotropically etching the etch termination surface to form the tapered surface of the cantilever and etching a predetermined portion of the device surface to release the end region of the cantilever.

Abstract: A waveguide display system may include an eyepiece waveguide that can have a first surface and a second surface, the waveguide including an incoupling diffractive optical element (DOE) and an outcoupling DOE. The waveguide display system may include a light source and a scanning mirror, and may include reflective and collimating optical elements. The incoupling DOE can be configured to selectively propagate incident light beams to the outcoupling DOE in the waveguide through total internal reflection (TIR).

Abstract: An automated method for categorising and describing rock samples includes: (i) capturing images of samples to generate image data; (ii) classifying the samples by applying convolutional neural network processing to the image data to identify attributes of the samples; (iii) extracting, using a module based on a trained convolution deconvolution neural network, salient features from the attributes to generate salient feature data; (iv) applying, using a module based on a trained recurrent neural network generated from supervised learning, semantic text processing to the salient feature data to generate sample text data indicative of the attributes; (v) storing the sample text data; (vi) searching an image database for categorised images that are similar to the captured images; and (vii) generating output data dependent upon a degree of similarity between the sample text data and the database text data to indicate petrophysical properties of the rocks.

Abstract: An optical scanner includes a cantilevered optical member protruding from the base portion and a transducer assembly comprising one or more piezoelectric actuators coupled to the cantilevered optical member and configured to induce motion of the cantilevered optical member in a scan pattern. In some cases, the cantilevered optical member has a tapered shape with a distal end narrower than a proximal end adjacent to the base portion of the optical scanner. In some cases, the cantilevered optical member has an elongated width along a first plane and includes a plurality of waveguides. The transducer assembly is configured to induce motion of the cantilevered optical member in a second plane orthogonal to the first plane.

Abstract: The present disclosure relates to a beverage machine for preparing a single serving of a mixed beverage and a capsule for use with the machine. The capsule includes an open shell defining a reservoir for holding ingredients; a lid for sealing the open shell; and, a guide member disposed within the reservoir of the open shell configured to receive a liquid stream injected by an injection needle of a beverage machine when the lid is pierced by the injection needle and to guide the liquid stream to a mixing zone within the reservoir for mixing the liquid stream with the liquid held in the reservoir to prepare a single serving of mixed beverage to be dispensed from the reservoir via a dispensing needle of the beverage machine when the dispensing needle pierces the open shell . . . .
