摘要： A switch matrix, a switch matrix assembly, and a magnetic resonance imaging (MRI) apparatus are disclosed. The switch matrix includes a first path to which an electric signal is applied; a first switching unit configured to selectively and electrically interconnect a first input unit and a first end of the first path or to open the first end of the first path; and a second switching unit configured to selectively and electrically connect a second input unit to a second end of the first path or to open the second end of the first path.

摘要： A switching multiplexor arrangement of relays having configuration flexibility and operative for balancing thermal offset of the relays Accumulated thermal offset of the relays along the various propagation paths through the multiplexor is balanced, by maintaining equal numbers of configured relays, along the various propagation paths, so that there are substantially equal amounts of accumulated thermal offset for the various propagation paths.

摘要： A two wire switching system is intended for use in a hostile environment such as a nuclear reactor where temperatures are in excess of 250.degree. or 300.degree. C. and where the use of a switch with a permanent magnet component or a component intended to have remanence is not desirable. The system uses eight reed switches each having three similar windings. No magnetized components are used. The switches are normally closed in the absence of a magnetic field and are opened when a net magnetic field results from current flowing through at least one winding. A pair of conductors interconnects the windings so that each conductor connects certain windings in a series arrangement to ground, giving a unique interconnection for each switch. A control current may be caused to flow in either conductor arrangement at a value of zero or plus or minus A or 2A amperes where A amperes is at least sufficient to cause actuation of a switch when it flows through one winding. It is not essential that the value of A amperes be constant so long as the ratio of plus or minus A:A or A:2A is constant. The switching system is suitable for connecting a selected one of eight temperature sensors across another pair of conductors to provide a temperature reading from the selected temperature sensor.
摘要翻译：双线切换系统旨在用于恶劣环境，例如温度超过250度或300度的核反应堆，并且使用具有永磁体组件或组件的具有剩磁性能的开关是不可取的。该系统使用八个簧片开关，每个具有三个类似的绕组。没有使用磁化元件。开关在没有磁场的情况下通常闭合，并且当由流过至少一个绕组的电流产生净磁场时打开。一对导体将绕组互连，使得每个导体将串联布置中的某些绕组连接到地，为每个开关提供唯一的互连。可以使控制电流在导体布置中以零值或正负A或2A安培流动，其中A安培至少足以在开关流过一个绕组时致动开关。只要正或负A：A或A：2A的比例恒定，A安培值不是必须的。开关系统适用于将另一对导体上的八个温度传感器中选定的一个连接到一起，以从所选择的温度传感器提供温度读数。

摘要： A switching device is provided which is of a highly integrated structure and particularly adapted for a matrix arrangement of switch elements. The structure characteristically enables the switching device to be efficiently fabricated with maximum component density and minimum cost, and includes a base plate in the form of an integral combination of two insulating plates lying on each other, fixed contacts formed in an appropriate pattern on one of the insulating plates, and movable contacts formed integrally with spring strips supported on the base plate.
