摘要： A mobile communications handset (12) is capable of connection through two different networks (2, 27). When it is out of contact with its preferred local wireless access system (27), the handset will seek a hand-over to the cellular network (2), and will become registered as a “roaming” handset currently connected to the cellular network (2). The cellular network (2) reports this location information to the call server (28), as it would to the HLR of any normal visiting handset, so that incoming calls to the PSTN (6) destined for the user (12) can be routed by way of the cellular network. Outgoing calls are handled as conventional cellular telephony calls. When contact with a local wireless access system (27) is re-established, the contact information is passed to the call server 28, which reports to the cellular network (2) that a handover has occurred. An interface between the call server (28) and cellular network (2) is configured such that the call server (28) emulates a base site controller of the cellular network (2). The cellular network therefore operates conventionally, with the handset (12) logged as operating through this quasi-base site controller. However, the cellular system would continue to register the presence of the handset as co-operating with the quasi-base station (28), even though it would have no visibility of most calls being made to and from the handset (12). This avoids the cellular system (2) attempting to seize control of the handset through a normal cellular base station (21).
摘要翻译：移动通信手机（12）能够通过两个不同的网络（2,27）进行连接。当它与其优选的本地无线接入系统（27）不接触时，手机将寻求对蜂窝网络（2）的切换，并且将被注册为当前连接到蜂窝网络的“漫游”手机（ 2）。蜂窝网络（2）向呼叫服务器（28）报告该位置信息，就像对任何正常访问手机的HLR一样，从而可以将去往用户（12）的PSTN（6）的呼入路由通过蜂窝网络。拨出呼叫作为传统蜂窝电话呼叫处理。当与本地无线接入系统（27）的接触被重新建立时，联系信息被传递给呼叫服务器28，呼叫服务器28向蜂窝网络（2）报告发生了切换。呼叫服务器（28）和蜂窝网络（2）之间的接口被配置为使得呼叫服务器（28）模拟蜂窝网络（2）的基站控制器。蜂窝网络因此常规地操作，手机（12）通过该准基地点控制器记录为操作。然而，蜂窝系统将继续将手机的存在注册为与准基站（28）合作，即使它对于进入和从手机（12）进行的大部分呼叫都不具有可见性。这避免了蜂窝系统（2）尝试通过正常的蜂窝基站（21）来占用手机的控制。

摘要： Systems and methods pertaining to propagation of digital data from a transmit side domain to a receive side domain through an intermediate isolation barrier are described. Specifically, a carrier waveform is superimposed upon a first logic level of a digital signal that is referenced to a first local ground. The digital signal with the superimposed first carrier waveform is propagated through the intermediate isolation barrier. On the receive side domain, the propagated digital signal is processed using a second local ground that is different than the first local ground, the processing including the use of the carrier waveform to enforce the first logic level upon an output digital signal generated from the propagated digital signal.

摘要： A device for producing an output voltage which is proportional to an applied magnetic field. The device includes a plurality charge injection regions, a corresponding plurality of charge exit regions, and a charge transfer region. The charge transfer region includes gate electrodes which serve to propagate at least one isolated charge packet across the charge transfer region in a predetermined direction from the charge input region to the charge output region. The charge packet is subject to the applied magnetic field which is perpendicular to the charge transfer region so as to induce a resultant potential that is orthogonal to both the applied magnetic field and the predetermined direction. Furthermore, the resultant potential effects a lateral redistribution of charge carriers in the packet. A recirculation configuration allows for a recycling of the packet from the output region back to the input region in order to accommodate a continuation of the redistribution of charge carriers. Sense contacts are provided with the recirculation configuration for sensing the resultant potential as the output voltage.

摘要： A micro-machined switching system for equalizing an electrical property, such as charge due to parasitic capacitance formed at an input and an output of a micro-machined switching device. The micro-machined switching device may be a MEMS relay or a MEMS switch. In addition to the micro-machined switching device, the switching system also includes a balancing module for equalizing the electrical property between the input and the output of the micro-machined switching device. In certain embodiments, the balancing module includes a switch operable in a first state causing charge due to the parasitic capacitance on the input and the output of the micro-machined switching device to substantially balance. The switch is also operable in a second state wherein parasitic capacitance can separately accumulate at the input and the output of the micro-machined switching device.

摘要： A non-optical isolator having a driver circuit for providing an input signal to one or more first passive components which are coupled across a galvanic isolation barrier to one or more corresponding second passive components, and an output circuit that converts the signal from the second passive components to an output signal corresponding to the input signal. The entire structure may be formed monolithically as an integrated circuit on one or two die substrates, for low cost, small size, and low power consumption. The passive components may be coils or capacitor plates, for example. When the first and second passive components are capacitor plates, a Faraday shield may be provided between them, with the first and second passive components being referenced to separate grounds and the Faraday shield referenced to the same ground as the second passive components.
