摘要:
A method for producing a tamper evident security holographic label and overlaminate using UV casting techniques, and a security device so produced, comprising a clear protective layer; a thin layer of clear UV cured resin cast partly onto the protective layer following a designed pattern; another layer of UV cured resin bearing a cast holographic image, wherein the bond of the holographic image layer is stronger toward the surface of the protective layer than it is toward the surface of the pattern layer; a reflective layer strongly attached to the adjacent holographic layer; and an adhesive layer bonded to the reflective layer. Such a composite product when adhered to a base substrate via the adhesive layer will show no visible security feature to the unaided eye due to the thin nature of the clear security pattern. But upon delamination attempts, the ultra-thin holographic image layer will be broken at the weakest interfacial bond which is between the two UV cured resin surfaces, providing visible evidence of tampering in the form of a break pattern identical to that of the clear pattern layer.

An emergency generator power system with reserved fire protection power includes a generator engine and a generator body, a main power circuit breaker, a control panel, and a circuit breaker for fire protection systems and a circuit breaker for other emergencies.The generator power system also includes a measuring instrument and a control instrument. The measuring system measures a power load change on a main power line passing via the main power circuit breaker. The control instrument is connected to the measuring instrument at an input side thereof and to the circuit breaker for other emergencies at an output side thereof. When the value of the power load change reaches a predetermined value, the circuit breaker for other emergencies is primarily broken, thereby keeping the main power circuit breaker from being broken before the breaking of the circuit breaker for other emergencies.

A material position information measuring section measures a position of a material lifted up by a tower crane. A structure information measuring section measures position information about surrounding structures. A route searching section searches for a route of movement of the material from a start point to a destination. The route of movement determined by the route searching section is stored in a route storage. A data processor receives data of the material position information measuring section and the structure information measuring section, and calculates 2D or 3D image data about relative positions of the tower crane, the material lifted up by the tower crane and the surrounding structures. A display unit displays information about at least one of the tower crane, the material and the surrounding structures using the image data calculated by the data processor, and displays the route of movement determined by the route searching section.

Methods and structures using laser bonding for stacking semiconductor substrates are described. In one embodiment, a method of forming a semiconductor device includes forming a trench in a first substrate, and a bond pad on a second substrate comprising active circuitry. A top surface of the bond pad includes a first material. The first substrate is aligned over the second substrate to align the trench over the bond pad. An electromagnetic beam is directed into the trench to form a bond between the first material on the bond pad and a second material at a bottom surface of the first substrate.

A metal-ceramic multilayer structure is provided. The underlying layers of the metal/ceramic multilayer structure have sloped sidewalls such that cracking of the metal-ceramic multilayer structure may be reduced or eliminated. In an embodiment, a layer immediately underlying the metal-ceramic multilayer has sidewalls sloped less than 75 degrees. Subsequent layers underlying the layer immediately underlying the metal/ceramic layer have sidewalls sloped greater than 75 degrees. In this manner, less stress is applied to the overlying metal/ceramic layer, particularly in the corners, thereby reducing the cracking of the metal-ceramic multilayer. The metal/ceramic multilayer structure includes one or more alternating layers of a metal seed layer and a ceramic layer.
