摘要： An electronic safe includes apparatus ID codes of various electronic devices as well as security keys associated with the apparatus ID codes. In order for an electronic device to be operated, it must first make connection with the electronic safe in order to verify the security key. Once the security key is received and verified, the electronic device is enabled to perform its function. However, if the security key is not received or not verified, the electronic device is disabled until such time as the security key is received and verified. This would effectively render stolen electronic devices unusable and worthless.
摘要翻译：电子保险箱包括各种电子设备的设备ID代码以及与设备ID代码相关联的安全密钥。为了使电子设备进行操作，必须首先与电子保险箱连接以验证安全密钥。一旦接收并验证安全密钥，电子设备就能够执行其功能。但是，如果未收到安全密钥或未验证安全密钥，则电子设备将被禁用，直至接收并验证安全密钥为止。这将有效地使被盗的电子设备无法使用而且毫无价值。

摘要： The present invention relates to an image projection system (1). The system (1) comprises an illumination system (3) with a light source (5) for supplying an illumination beam. The system (1) also comprises a modulation system (11) with at least one reflecting image display panel (13, 15, 17) for modulating this light beam in conformity with image information to be projected, and a projection lens system (12) for projecting this image information. A color-separating system (19) is arranged between the modulation system (11) and the illumination system (3), and a polarizing beam splitter (9) is arranged between the color-separating system (19) and the illumination system. The reflective display panel is a liquid crystalline display panel of the diffusing type, and a lambda /4 plate (35, 37, 39) is arranged between the reflective portions of the pixels of the display panel and the polarizing beam splitter.

摘要： The invention relates to an illumination system (21) for supplying a polarized radiation beam. The illumination system (21) successively comprises a radiation source unit (3) for supplying at least one radiation beam and an optical system for concentrating the radiation to a beam, a polarizing system (11) for splitting a radiation beam (bI, bII) generated by the radiation source unit (3) into linearly polarized sub-beams, and at least one polarization-rotating element (35). The polarizing system comprises at least one optically transparent plate (11) having a refractive index n0 and a first face and a second face. At least one of these faces is provided with an optically thin layer having a refractive index n1 which is larger than n0. The light path of the sub-beams whose directions of polarizations are not to be converted incorporates a reflector (41, 43) for reflecting the sub-beams into the same direction of propagation as that of the other sub-beams. The chief ray of these beams and the normal on the plate (11) enclose an angle which is substantially equal to the Brewster angle which holds for the interface between the optically thin layer and a medium surrounding the polarizing element (11). The radiation source unit (3) comprises two radiation sources (23, 25), and such a polarizing system is associated with each radiation source (23, 25). The invention also relates to an image projection device (45) comprising such an illumination system (21).
