摘要:
A multilayer photovoltaic compound to be applied to outer surfaces of any movable and/or stationary support for absorption and conversion of light radiation into electrical energy comprising, in the following order, at least one first layer (1 ) designed to adhere to the surface (S) of the support (T), at least one second layer (2) of an electrically conductive material which defines an electrode, at least one third optoelectronically active layer (3) designed to absorb photons and convert them into electrical energy, at least one fourth layer (4) of an electrically conductive material which defines a counter-electrode. The first layer (1 ) is formed of a substantially homogeneous and continuous base material, which is chemically and mechanically inert to the other layers (2, 3, 4) to define a universal anchoring base adaptable to surfaces of any shape and size. A fifth layer (5) of an optically transparent and electronically inert material may be possibly deposited on the underlying layers (1, 2, 3, 4) to protect and encapsulate them, thereby forming a single hermetically sealed unit.

A measuring device for detecting impact stresses on a protection barrier (B), wherein the barrier (B) comprises a plurality of posts (M) adapted to support at least one substantially flexible retainer element (R) for collecting falling material, and wherein each post (M) is designed to be associated with at least one foundation (F) for anchorage to a stationary support (S). Each post (M) is equipped with at least one interface element (2) designed to be anchored to the upper end (3) of the foundation (F) and to the lower end (4) of the post (M), and first detection means (5, 105) associated with the interface element (2) for measuring the compressive/tractive forces acting on the post (M) in a substantially axial direction. Second detection means (6, 106) are associated with the interface element (2) for measuring the shear stresses acting on the post (M) in a substantially transverse direction, as well as means for collecting data from the first (5; 105) and second (6; 106) detection means, for instantaneous detection of the multi-axial stress state of the corresponding post (M) upon impact.

摘要:
An amplifier circuit (300) that offers high bandwith operation and a high slew rate is disclosed. The amplifier circuit may also have an input voltage swing down to the negative rail which is particularly suitable for low voltage applications having a single power source. In one embodiment, the amplfiier circuit amplifies a difference voltage between first and second input voltages (V1, V2) to produce and output voltage, and includes: an analog voltage-to-current converter (302) for receiving the first and second input voltages (V1, V2) and producing complementary current signals; and a complementary mirror output stage (304) coupled to receive the complementary current signals at respective mirror circuits. Each of the respective mirror circuits includes a pair of base-coupled transistors having their emitters respectively connected to supply potentials through resistors, and the complementary current signals from the analog voltage-to-current converter (302) are respectively connected to at least one of the emitters of the base-coupled transistors for the respective mirror circuits.
