    摘要： Shifter circuits comprise a matched translation stack comprising at least first and second stacks each of which comprising multiple transistors. The matched translation stack is configured to provide a primary logic level shift between a voltage level away from which a shift is desired (VddL) and a voltage level to which the shift is desired (VddH). One or more high voltage buffer stages are provided, at least one of which being connected with and biased by the matched translation stack. At least one high voltage buffer stage comprises multiple transistors arranged in a transistor stack that is biased by the first stack of the matched translation stack, and is connected to receive an input supplied by the second stack of the matched translation stack. The high voltage buffer stage also comprises an inverter that drives an output stage which is also driven by a low voltage buffer stage.

    摘要： Process for the manufacture of hydrated lead oxides in the bivalent state characterized by the step of (1) reacting metallic lead with acetic acid (e.g. ammonium acetate, 5%-30% solution) at a temperature up to 200.degree. C. (e.g. 50.degree.-200.degree. C.) under an atmosphere of an oxygen containing gas (e.g. oxygen) of between 1 and 10 atmospheres absolute pressure to form lead acetate, then (2) reacting the lead acetate with a source of ammonium ion (e.g. ammonia) under an absolute pressure between 1 and 5 atmospheres at a temperature up to 100.degree. C. (e.g. 60.degree.-90.degree. C.) to precipitate lead oxides and, optionally, to produce tri- and tetra- basic lead sulphates, by (3) adding to the lead oxides so precipitated sulphuric acid in the stoichliometric amount to produce tri- or tetra- basic lead sulphate, then (4) separating and drying the tri- or tetra- basic lead sulphate so formed.

    摘要： A fastener for fastening pipes or electrical conduit can be installed with the optional use of nails or screws. The fastener includes sharp teeth or spikes which can be hammered into an external surface, such as wood or masonry. The teeth or spikes are positioned, oriented, and otherwise configured to best suit the intended application. Installation can be accomplished using only the fastener itself and force exceeding a minimal threshold.

    摘要： A method of controlling ads includes receiving a beacon over a network identifying an ad, an end user and a content source; querying a database of unauthorized content sources based on the beacon; determining whether the ad is an unauthorized impression; and storing information from the beacon in a database, including whether the impression was authorized or unauthorized. The database may include a list of unauthorized sites and the querying may include checking whether the content source is one of the unauthorized sites. Querying also may be used by advertising exchanges and networks to determine whether to place an ad on a particular publisher's site.

    摘要翻译： 控制广告的方法包括：通过标识广告，最终用户和内容源的网络接收信标; 基于信标查询未经授权的内容源的数据库; 确定广告是否是未经授权的展示; 以及将来自信标的信息存储在数据库中，包括该展示是否被授权还是未被授权。 数据库可以包括未经授权的站点的列表，并且查询可以包括检查内容源是否是未经授权的站点之一。 广告交易所和广告网络可以使用查询来确定是否在特定发布商的网站上放置广告。
