Abstract: An on-chip spectroscopic sensor includes a tunable diode laser. A laser driver for drives the tunable diode laser. An analyte test cavity receives a chemical sample and exposes the received chemical sample to light from the tunable diode laser. An optical detector detects light emerging from the analyte test cavity as a result of the laser exposure. A spectral analyzer determines a spectrum of the emerging light, matches and removes one or more known optical fringe patterns from the determined spectrum, and determines a composition or concentration of the chemical sample from the optical fringe pattern-removed spectrum.

Abstract: An exemplary microphone capture simulation system accesses a captured set of audio signals captured by a plurality of directional microphones disposed at a plurality of locations on a perimeter of a capture zone of a real-world scene. The system identifies a location within the capture zone that corresponds to a virtual location at which a user is virtually located within a virtual reality space that is based on the capture zone. Based on the captured set of audio signals and the identified location, the system generates a simulated set of audio signals representative of a simulation of a full-sphere multi-capsule microphone capture at the identified location. The system processes the simulated set of audio signals to form a renderable set of audio signals configured to be rendered to simulate full-sphere sound for the virtual location while the user is virtually located at the virtual location.

Abstract: An exemplary ambient sound extraction system accesses a location-confined A-format signal that includes a first set of audio signals captured by different capsules of a multi-capsule microphone disposed at a first location with respect to a capture zone of a real-world scene. The ambient sound extraction system also accesses a second set of audio signals captured by a plurality of microphones disposed at a plurality of other locations with respect to the capture zone. The ambient sound extraction system generates a location-diffused A-format signal. The location-diffused A-format signal includes a third set of audio signals that is based on the first and second sets of audio signals. Based on the location-diffused A-format signal, the ambient sound extraction system generates a location-diffused B-format signal representative of ambient sound in the capture zone. Corresponding methods are also disclosed.

Abstract: Solutions, systems, and techniques for applying 2-dimensional changes to a shared document are discussed. The document is divided into vertical columns of a particular width, each column represented as a one-dimensional vector that is a sequential list of blocks in that column, each block representing a content item included in the document. Each block has a starting column, a block height, and a block width indicated by how many columns the block occupies. Each block has row indexes that represent a relative position of the block in each column it occupies. A document modification command is represented as transfer functions, each transfer function corresponding to a document column. The transfer functions are applied to the document columns to alter a row index of block(s) in the corresponding column(s), thereby altering the relative position of a block with respect to other blocks in that column.
