An automatic sound field correcting device executes a signal process to the plurality of audio signals on respective correspondent signal transmission paths, and outputs them to a plurality of correspondent speakers to correct sound characteristics on the respective signal transmission paths. Namely, a measurement signal is supplied to each signal transmission path, and a measurement sound corresponding to it is outputted from the speaker to a sound space. The outputted measurement sound is detected as a detecting signal. The frequency characteristic of the audio signal on each signal transmission path is corrected by an equalizer, and a gain value of the equalizer is determined by a correction amount determining unit. A frequency characteristics correction is performed predetermined times. At a first correction, the correction amount determining unit determines the correction amount by performing a frequency analysis, based on the detecting signal, i.e. base on the detecting signal corresponding to the measurement sound actually outputted to the sound space. On the contrary, at and after a second correction, the correction amount determining unit determines the correction amount based on the detecting signal or an output signal of the equalizer. Namely, at and after the second correction, the output signal of the equalizer is supplied to the correction amount determining unit in a signal processing circuit as the need arises, and the frequency characteristics correction is performed without actually outputting the measurement sound to the sound space.

An electronic flash-memory card has additional pipes for commands and status messages so that data pipes are not clogged with commands and status messages, allowing for a higher data throughput. The command and status pipes are activated when a UAS / BOT detector detects that a host is using a USB-Attached-SCSI (UAS) mode rather than a Bulk-Only-Transfer (BOT) mode. The host can send additional commands and data without waiting for completion of a prior command when operating in UAS mode but not while operating in BOT mode. A command queue (CQ) in the device re-orders commands for accessing flash memory and merges data in a RAM buffer. Smaller 1 KB USB packets in the data pipes are merged into larger 8 KB payloads in the RAM buffer, allowing for more efficient flash access.

Optical detection platforms are described as well as methods of using such platforms to perform quantitative assays.

A processor having a reduction unit that sums m input operands plus an accumulator value, with the option of saturating after each addition or wrapping around the result of each addition. The reduction unit also allows the m input operands to be subtracted from the accumulator value by simply inverting the bits of the input operands and setting a carry into each of a plurality of reduction adders to one. The reduction unit can be used in conjunction with m parallel multipliers to quickly perform dot products and other vector operations with either saturating or wrap-around arithmetic.

A multi-functional data processing pipeline is disclosed where the multi-functional pipeline comprises a plurality of pipelined data processing engines, the plurality of pipelined data processing engines being configured to perform processing operations. The multi-functional pipeline can be configured to controllably activate or deactivate each of the pipelined data processing engines in the pipeline in response to control instructions and thereby define a function for the pipeline, each pipeline function being the combined functionality of each activated pipelined data processing engine in the pipeline. In example embodiments, the pipelined data processing engines can include correlation logic, and such pipelines can be used to accelerate convolutional layers in machine-learning technology such as convolutional neural networks.

A biometrics authentication device identifies characteristics of the body from captured images of the body and performs individual authentication. The device guides a user, at the time of verification, to the image capture state at the time of registration of biometrics characteristic data. At the time of registration of biometrics characteristic data, body image capture state data is extracted from an image captured by an image capture unit and is registered in a storage unit, and at the time of verification the registered image capture state data is read from the storage unit and is compared with image capture state data extracted at the time of verification, and guidance of the body is provided. Alternatively, an outline of the body at the time of registration, taken from image capture state data at the time of registration, is displayed.
