    • A bistable display device comprises two walls enclosing an optically transparent sheet (2) having a plurality of cavities (13) each containing a rotatable bicoloured ellipsoidal particle (14) within a liquid carrier (15), and electrodes (6, 7) for applying an electrical field across the sheet. The device has bistability and may be addressed in a multiplex or direct drive manner. The carrier liquid may be of low viscosity at device, near ambient, operating temperature. Alternatively the carrier liquid may be solid or almost solid at ambient temperatures, and the liquid heated before the device is addressed.

    • The present invention relates to an improved sensor arrangement, a system and method for determining the rate of ice formation and how close conditions are to those at which ice will form on a surface, and to an improved sensor arrangement for use therein. The sensor arrangement comprises a means (11,12,14) for measuring the thermal lag, heating and cooling of a thermally conductive element, which is comprised of a first and second surface (15a, 15b), said first surface exposed to the environment, wherein the surface area of said first surface is smaller than the second surface. The step of ice detection may be performed by either a passive measuring system wherein the latent heat of ice formation is measured via the temperature differential across a Peltier element. In an alternative arrangement the detector may preferably be an active system comprising heating or cooling the Peltier device and, whilst such heating or cooling is being conducted, also measuring the temperature of the exposed outer first surface using a separate temperature detector.
    • 本发明涉及一种改进的传感器布置,用于确定冰的形成速率的系统和方法以及与表面上将会形成冰的条件相关的条件以及用于其中的改进的传感器布置。 传感器装置包括用于测量由第一和第二表面(15a,15b)组成的导热元件的热​​滞后,加热和冷却的装置(11,12,14),所述第一表面暴露于环境 ,其中所述第一表面的表面积小于所述第二表面。 冰检测的步骤可以通过被动测量系统来执行,其中通过珀尔帖元件的温度差来测量冰的潜热。 在替代布置中,检测器可以优选地是包括加热或冷却珀耳帖装置的有源系统,并且在进行这种加热或冷却的同时,还使用单独的温度检测器来测量暴露的外部第一表面的温度。
