    摘要： Calcium channel blocking activity is exhibited by compounds having the formula ##STR1## or a pharmaceutically acceptable salt thereof, wherein the stereochemistry at the chiral centers in the 3 and 4-positions of the benzothiazepine nucleus is cis, and whereinR.sub.1 is alkyl, aryl, arylalkyl, alkenyl or alkynyl;R.sub.2 and R.sub.5 are each independently hydrogen, alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, halogen or trifluoromethyl; andR.sub.3 and R.sub.4 are each independently alkyl or cycloalkyl or R.sub.3 and R.sub.4 together with the nitrogen atom to which they are attached are pyrrolidinyl, piperidinyl or morpholinyl.

    摘要： An arrangement (20) for locating at least one device (22) utilizes an assisted global positioning system technique based upon Internet communications. In a disclosed example, a network server (26) detects the presence of a device (22) on the Internet (24). The network server (26) makes an initial estimate of a location of the device based upon Internet information regarding the device (22). The initial estimate is used by a location server to generate an assisted global positioning system communication that is provided to the device (22). An assisted global positioning system receiver (72) associated with the device (22) uses the received communication for interacting with a global positioning system (32). An indication of that interaction can then be used by the network server (26) or the location server (28) for making an actual device location determination.

    摘要： A wireless communication network (20) including mobile applications (56-62) includes a security approach that uses a combination of at least two techniques (42, 50, 54, 72). One disclosed example includes a combination of all four techniques. The combined, layered approach greatly reduces the probability that an unauthorized individual will be able to masquerade as a valid application within the network so that network security is improved. Disclosed techniques include obfuscating software code of a mobile application, providing a mobile application with a plurality of code signatures for generating a corresponding plurality of unique control values, limiting the useful lifetime of a mobile application and determining that a control value of a mobile application corresponds to the control value of another application before the two applications are allowed to interact in a manner that could compromise either application or the network.

    摘要翻译： 包括移动应用（56-62）的无线通信网络（20）包括使用至少两种技术（42,50,54,72）的组合的安全方法。 一个公开的示例包括所有四种技术的组合。 组合的分层方法大大降低了未经授权的个人将能够伪装成网络内的有效应用程序，从而提高网络安全性的可能性。 公开的技术包括对移动应用的软件代码进行模糊处理，为移动应用提供多个代码签名，用于生成对应的多个唯一控制值，限制移动应用的有用寿命并确定移动应用的控制值对应于 在允许两个应用程序以可能损害任一应用程序或网络的方式进行交互之前的另一个应用程序的控制值。
