IPC: B60L15/00
Filed: 2009-12-03
Abstract: <P>PROBLEM TO BE SOLVED: To provide an electric vehicle which can travel at an emergency even if a voltage of a battery is lowered below a rated voltage.  <P>SOLUTION: Even if the voltage of the battery is lowered below the rated voltage, when a driver selects front wheel drive by a low-output motor, traveling speed is further decelerated, but take-out power is increased, thus enabling the emergency traveling.

IPC: H05B37/02
Filed: 2007-10-02
Abstract: The invention relates to a method of controlling a temporal variation of light emitted by an illumination system. The light emitted by the illumination system varies from light having a start color point (14) to light having a target color point (12). The start and target color point are defined in a first color space (XYZ, RGBvid, RGBill), which is perceptually non-uniform. The method according to the invention converts the start and target color point from the first color space to a second color space (Lab, Lch), which is more uniform to the human visual system than the first color space. The method further comprises a step of generating an intermediate color point (34, I1, I2) located on a transition-path (p, p′) within the second color space, an intermediate distance (d) between the start color point in the second color space and the intermediate color point in the second color space not being larger than a threshold distance (26). The method further comprises converting the intermediate color point from the second color space back to the first color space, and subsequently altering the light emitted by the illumination system (65) from the start color point to the intermediate color point. The invention further relates to an illumination system and a display device.

Abstract: 【課題】尿中のホルムアルデヒドの存在を検出する簡単な技術を提供する。 【解決手段】尿サンプル（例えば尿または尿中物質）中のホルムアルデヒドの存在を迅速に検出する方法が提供される。この方法は、尿サンプルを基質と接触させるステップを含み、基質上にはホルムアルデヒドの存在下で検出可能な色の変化を遂げることができる着色剤が配置されている。理論に制限されるつもりはないが、ホルムアルデヒドによる着色剤の酸化は、スペクトルの赤端部に向かう（「深色移動」）かまたはスペクトルの青端部に向かう（「浅色移動」）吸収最大値の移動を誘発すると考えられている。吸収移動は、視覚的にあるいは器具を介して検出可能な色差を与え、尿サンプル内のホルムアルデヒドの存在を示す。例えば、尿サンプルとの接触前は、着色剤は、無色またはある種の色を持ち得るが、尿サンプルとの接触及びホルムアルデヒドとの反応後は、最初の色とは異なる色を呈する。 【選択図】  図１
