Abstract: The techniques described herein relate to a systems and methods for a digital asset generation platform. The digital asset generation platform may ingest an ingest input. The digital asset generation platform may utilize a document identification engine corresponding to a first stage of a multi-stage convolutional neural network for identifying document types of documents. The digital asset generation platform may utilize an object detector engine corresponding to a second stage of the multi-stage convolutional neural network for detecting a dynamic mapping in the digital file. The digital asset generation platform may utilize a post-processing engine for classifying the dynamic mapping in the at least one digital file. The digital asset generation platform may dynamically generate a digital asset representative of the document based on the key value data pairs extracted from the dynamic mapping.

Abstract: A device for collecting and distributing material into a receptacle having a receptacle curvature includes: a tapered wall; and a tamping flange adjoining the tapered wall. The tapered wall has a tapered wall curvature that approximates the receptacle curvature. The tamping flange is configured to compact the material into the receptacle.

Abstract: An apparatus, system and method are provided for testing a battery-powered electronic device-under-test in a transport frame engaged with a test fixture. A transport frame power supply is arranged to provide power to the DUT in a pre-testing stage. A switching circuit is arranged to switch from the transport frame power supply to a test fixture power supply in response to receiving a power switching signal indicating satisfaction of a pre-testing condition. Power from the test fixture power supply can then be switched back to the first transport frame, or to a second transport frame, to begin testing a second DUT. The ability to start a DUT test without having to wait for the DUT to boot-up in the test fixture reduces test time and increases efficiency of use of test equipment.

Abstract: A loudspeaker comprising a horn waveguide having a throat and a waveguide surface; an acoustic radiator assembly, located at the throat of the waveguide, comprising a diaphragm having a rigid acoustically radiating surface shaped as a section from a toroidal surface for generating acoustic wavefronts, the waveguide surface being adapted to match the shape of the wavefronts coming from the assembly.

Abstract: An electro-acoustic transducer with a front part having an acoustically radiating surface, a supporting part that supports the front part and that extends from a peripheral region of the front part in a direction away from the acoustically radiating surface, and a reinforcing part that provides rigidity to the transducer. The reinforcing part extends from the supporting part to the front part such that a portion of the reinforcing part is spaced from the front part and/or the supporting part.

Abstract: A phase plug comprises a body having an input side for receiving acoustic waves and an output side for transmitting acoustic waves, the body including a plurality of channels extending from the input side to the output side for propagating acoustic waves through the body. The input side comprises an input surface which includes a plurality of openings constituting entrances for the channels, the input surface being substantially part of a sphere or an ellipsoid in shape. The areas of the openings vary with radial position on the input surface, the radial position being measured in a direction extending perpendicularly from a central axis extending through the input surface. The variation in the areas is a function of the cosine of an angle subtended at the centre of the sphere or a focus of the ellipsoid between the central axis and the radial position.

Abstract: A phase plug comprises a body having an input side for receiving acoustic waves and an output side for transmitting acoustic waves, the body including a plurality of channels extending from the input side to the output side for propagating acoustic waves through the body. The input side comprises an input surface which includes a plurality of slots constituting entrances for the channels, each slot being arranged in a substantially radial orientation on the input surface about a central axis extending through the input surface.

Abstract: A loudspeaker comprises a horn waveguide having a waveguide surface, and a transducer located in, or adjacent to, a throat of the horn waveguide. The transducer has a substantially rigid convex dome-shaped acoustically radiating surface. A horn angle subtended between a longitudinal axis of the horn waveguide and the waveguide surface at the throat of the horn, is in the range 20 to 60 degrees. An intersection angle subtended between a plane tangential to the dome shape of the acoustically radiating surface and a plane tangential to the waveguide surface at a point where the dome shape or an extrapolation of the dome shape meets the waveguide surface or an extrapolation of the waveguide surface, is in the range 85 to 110 degrees.

Abstract: A loudspeaker or other enclosure 10 constituting a humidity sensitive region the moisture of which is to be reduced contains a heater 18A. The tube 12 having a bore narrow enough to prevent diffusion of gases therethrough leads from the enclosure 10. The heater is operated cyclically by a switching circuit 19 to heat the interior of the enclosure to expel moist air through the tube 12 and thereby control the humidity of the air in the enclosure. A dessicant 16 may be provided in the tube 12. A heater 18B may be provided in the tube instead of in the enclosure.
