Abstract: 【課題】 ミクロ分析データキューブのスペクトルミクロ分析及び統計学的分析を遂行する方法、並びにこのような方法を実施するための装置及びシステムを提供する。
【解決手段】 スペクトルミクロ分析を遂行するためのシステムは、データ収集の進行中に分析結果を与える。 試料におけるピクセルからスペクトルが収集されるにつれて、このシステムは、スペクトルを周期的に分析して、提案される試料成分を表す基礎的スペクトルを統計学的に導出し（Ａ）、この導出されたスペクトルは、変化する割合で合成されて、各ピクセルにおいて測定されたスペクトルを（少なくとも近似的に）生じさせる。 次いで、同じ優勢な提案される成分を有し、及び／又は提案される成分の少なくともほぼ同じ割合を含むピクセルは、それらの測定されたスペクトルを合成（即ち、加算又は平均化）することができる（Ｃ、Ｄ）。 次いで、これらのスペクトルは、基準ライブラリーを経て相互参照され、実際に存在する成分を識別することができる（Ｅ）。 前記分析中に、前記測定されたスペクトルは、好ましくは、その測定されたスペクトルを構成するエネルギーチャンネル／インターバルの数を減少することにより及び／又は隣接ピクセルの測定されたスペクトルを合成することにより凝縮されて、データキューブのサイズを減少すると共に、分析結果を促進させる（Ｇ）。

Abstract: A method for calculating 19 biological parameters associated with the light absorption of human skin by means of a mathematical model. This method establishes a relevance between the skin spectrum and the biological parameters associated with light absorption in the epidermal/dermal layer of skin, by establishing two levels of analytical models, namely, a skin spectral analysis model and a mathematical model of biological parameters in the skin associated with the light absorption, achieves virtual spectrums which are stimulated by a set of skin parameters, and then performs optimization iteration by information processing technology using the virtual spectrums and the actual spectrums, to find a set of optimized results which meets a specific standard of the goodness of fit, thus reaching the goal of quantitatively analyzing biological parameters associated with the light absorption in human skin.

Abstract: An optical system comprises a wearable device for measuring one or more physiological parameters. The physiological parameters may change in response to stretching of the hand or movement of fingers or thumb of the user, or the parameters may be related to blood constituents or blood flow. The wearable device comprises a light source with a plurality of semiconductor diodes and a detection system that measures reflected light from tissue comprising skin. The semiconductor diodes may be light emitting diodes or laser diodes. The signal to noise ratio for the output signal may be improved by synchronizing the detection system to the light source, increasing light intensity of at least one of the plurality of semiconductor diodes from an initial light intensity, and using change detection that compares light on versus light off for the detection system output. The wearable device is also configured to identify an object.

Abstract: A method for determining national crop yields during the growing season is provided. In an embodiment, a server computer system receives agricultural data records for a particular year that represent covariate data values related to plants at a specific geo-location at a specific time. The system aggregates the records to create geo-specific time series for a geo-location over a specified time. The system creates aggregated time series from a subset of the geo-specific time series. The system selects a representative feature from the aggregated time series and creates a covariate matrix for each specific geographic area in computer memory. The system determines a specific crop yield for a specific year using linear regression to calculate the specific crop yield from the covariate matrix. The system determines a forecasted crop yield for the specific year using a sum of the specific crop yields for the specific year, as adjusted.
