Abstract: The present invention refers to an indirect vision device for vehicles integrating a lighting unit, like light indicators or light decorative elements, preferably for vehicles. The lighting device (1) comprises: a light source (2), a light guide (5) for guiding light emitted by the light source (2). The light guide (5) comprises a light guide material and scattering particles (10) admixed therein, and the refractive index of the scattering particles (10) is different than the refractive index of the light guide matrix material, such that light guided by the light guide (5), can be scattered by the scattering particles (10) out of the light guide (5). The invention provides an indirect vision device with enhanced homogeneous luminance and increased luminance.

Abstract: Various embodiments are generally directed to hardening the performance of calculations of a digital signature system for authenticating computing devices against side-channel attacks. An apparatus comprises a processor circuit and an interface operative to communicatively couple the processor circuit to a network; a storage communicatively coupled to the processor circuit and arranged to store instructions operative on the processor circuit to digitally sign a message to create a first signature using a modular arithmetic operation arranged to compensate for a value of a variable greater than a modulus without use of a branching instruction; and transmit the first signature to a verifying server via the network. Other embodiments are described and claimed herein.
