Electro-active lenses with raised resistive bridges
Resistive bridges can connect many ring electrodes in an electro-active lens with a relatively small number of buss lines. These resistors are usually large to prevent excessive current consumption. Conventionally, they are disposed in the same plane as the ring electrodes, which means that the ring electrodes are spaced farther apart or made discontinuous to accommodate the resistors. But spacing the ring electrodes farther apart or making them discontinuous degrades the lens's optical quality. Placing the ring electrodes and resistors on layers separated by an insulator makes it possible for the ring electrodes to be closer together and continuous with resistance high enough to limit current consumption. It also relaxes constraints on feature sizes and placement during the process used to make the lens. And because the resistors and electrodes are on different planes, they can be formed of materials with different resistivities. |

A cash management system utilizes a cloud computing model wherein a cloud of one or more servers may be locally networked or may be geographically dispersed and accessed by the client device over the Internet. The client device is a cash management safe. More than one safe may be employed in a system. Metrics, control functions, and interactions normally handled by an autonomous safe are shunted directly to a cloud server on the network. Usage data, currency validations, coin validations, security entries, etc. are communicated to the cloud server. The cloud server(s), based on database information and software settings, can transmit configuration, updates and information to remote safes. The information transmitted may include user configuration, access rules, currency configuration, alert configuration, and software and firmware updates. The cloud server based cash management system allows the entire cash management of an enterprise to be provided as a service to that enterprise. |

Process for coating an article and coating produced thereby
The invention relates to a process for coating an article (1), wherein a coating (2) having one or more coating layers (3, 4, 5) is applied to the article (1), wherein at least one coating layer (5) is formed essentially from aluminium, titanium and nitrogen, wherein the coating layer (5) has, at least in some regions, adjoining lamellae of different chemical composition and is deposited from a gas phase comprising at least one aluminium precursor and at least one titanium precursor. According to the invention, by setting a molar ratio of aluminium to titanium, the lamellae of different chemical composition are each formed with a cubic structure, it being possible for aluminium and titanium to be partly replaced by other metals and for nitrogen to be partly replaced by oxygen and/or carbon with retention of the cubic structure. The invention further relates to a correspondingly produced coating (2). |

Film forming method and film forming apparatus
A film forming apparatus comprises a film forming vessel comprising a first mold and a second mold that is arranged to be opposed to the first mold. The first mold is configured to include a first recessed portion and a first planar portion arranged around the first recessed portion and an exhaust port in a bottom portion of the first recessed portion. The film forming apparatus also comprises a seal member placed between the first planar portion of the first mold and the second mold. The seal member is configured to keep inside of the film forming vessel airtight; and an exhaust device connected with the exhaust port. The work is placed away from the first planar portion such that a film formation target part of the work faces an internal space of the first recessed portion when the film forming vessel is closed. A film forming method comprises (a) forming a film on part of the work by the film forming apparatus; (b) opening the film forming vessel after the (a); and (c) at a start of the (b), evacuating the film forming vessel via the exhaust port by the exhaust device. |

Rare earth thin-film magnet and method for producing same
A rare earth thin-film magnet of a Nd—Fe—B film deposited on a Si substrate, wherein, when the film thickness of the rare earth thin film is 70 μm or less, the Nd content satisfies the conditional expression of 0.15≤Nd/(Nd+Fe)≤0.25 in terms of an atomic ratio; when the film thickness of the rare earth thin film is 70 μm to 115 μm (but excluding 70 μm), the Nd content satisfies the conditional expression of 0.18≤Nd/(Nd+Fe)≤0.25 in terms of an atomic ratio; and when the film thickness of the rare earth thin film is 115 μm to 160 μm (but excluding 115 μm), the Nd content satisfies the conditional expression of 0.20≤Nd/(Nd+Fe)≤0.25 in terms of an atomic ratio. An object of the present invention is to provide a rare earth thin-film magnet having a maximum film thickness of 160 μm and which is free from film separation and substrate fracture, and a method of producing such a rare earth thin-film magnet by which the thin film can be stably deposited. |
