Abstract: Techniques for audio understanding using fixed language models are provided. In one aspect, a system for performing audio understanding tasks includes: a fixed text embedder for, on receipt of a prompt sequence having (e.g., from 0-10) demonstrations of an audio understanding task followed by a new question, converting the prompt sequence into text embeddings; a pretrained audio encoder for converting the prompt sequence into audio embeddings; and a fixed autoregressive language model for answering the new question using the text embeddings and the audio embeddings. A method for performing audio understanding tasks is also provided.

Abstract: This invention provides an extendable multipod for mounting an apparatus, comprising: a) an apparatus mount that allows rapid mounting and dismounting of an apparatus, wherein the apparatus mount is attached to one end of an extendable device; b) an extendable device comprising a plurality of tubular poles which are mounted so as to be telescopically and axially slidable relative to each other between an extended position and a retracted position, and the extendable device is attached to a supporting element; and c) a supporting element comprising a plurality of legs that are connected to a divaricating plate, wherein the extendable device is inserted through the divaricating plate to affix on a leg connector, and the leg connector is connected to the plurality of legs by a plurality of braces. Furthermore, the extendable multipod comprises a built-in power supply.

Abstract: The present invention provides a lighting device including (i) one or more LED chips positioned on one or more LED chip bases; (ii) one or more lens bases each of which includes one or more lenses, said lens comprises coatings for changing color temperature of the light produced by said LED chips and transmitted through said lens; and (iii) a motion transmission system to change the position of said lens bases relative to said LED chip bases, wherein each of said lenses is placed along the light path of one or more LED chips, and said lens changes the light beam cone angle of light emitted from said LED chips to produce long distance high intensity illumination. In one embodiment, the lens bases can be moved in a direction parallel to the optical axes of said lens, or moved on a plane that is parallel to said LED chip bases.
