摘要： In some embodiments, a mechanical adapter may be used to couple a first circuit board (e.g., a motherboard) to a second circuit board (e.g., a daughtercard) in a module. The mechanical adapter may have a mounting portion and a configurable portion. In some embodiments, the mounting portion may be similar for multiple configurations of the mechanical adapter. In various embodiments, the motherboard may be similar for different modules. For example, the mechanical adapter may be configured to mount a specific type of daughtercard in the configurable portion, while the mounting portion may be similar to mounting portions on other mechanical adapters with different configurations for different daughtercards (e.g., the motherboard may be similar for each of the different configurations). Therefore, in various embodiments, a common mounting portion may mate to a common motherboard configuration for different products each configured to mount a different daughtercard.

摘要： An isolation system for allowing a single measurement circuit to measure both low and high voltage signals from separate low and high voltage buses, respectively, while maintaining substantial isolation protection for humans or animals potentially exposed to the low voltage bus. A central relay coupled to the measurement circuit selects between the low and high voltage buses and thus provide one level of isolation. Two mutually exclusive relays on either side of the central relay provide another level of isolation. Since the central and the two mutually exclusive relay are all rated at the basic insulation level, the low and high voltage buses are separated by at least two relay levels thereby meeting the double insulation or high voltage testing standard during normal operation. For additional protection, should one or more of the relays fail, dual spark gaps limit the maximum voltage to an intermediate voltage level. Clamp circuits further limit the voltage appearing on the low voltage bus to below the hazardous voltage level. The spark gaps protect the maximum voltage appearing across the clamp circuits and the clamp circuits further limit the maximum voltage across the low voltage bus. Furthermore, in-series fuses isolate the high voltage from the low voltage bus if the high voltage hazardous condition exists for a significant period of time. Thus, at least three levels of protection are provided.

摘要翻译： 隔离系统允许单个测量电路分别测量来自分开的低压和高压母线的低压和高压信号，同时为潜在暴露于低压母线的人类或动物保持实质的隔离保护。 耦合到测量电路的中央继电器在低压母线和高电压母线之间进行选择，从而提供一级隔离。 中央继电器两侧的两个互斥继电器提供了另一个隔离级别。 由于中央和两相互独立的继电器均额定在基本绝缘水平，所以低压和高压母线由至少两个继电器电平分开，从而在正常运行期间达到双重绝缘或高压测试标准。 为了额外的保护，如果一个或多个继电器故障，双火花隙将最大电压限制到中间电压电平。 钳位电路进一步将低压母线上出现的电压限制在危险电压水平以下。 火花隙保护钳位电路两端出现的最大电压，钳位电路进一步限制低压母线上的最大电压。 此外，如果高压危险条件存在很长时间，串联保险丝将高电压与低压母线隔离。 因此，提供至少三个级别的保护。

摘要： A dimensionally flexible sparse matrix comprising multiple ports connected to a plurality of interconnected universal switches is disclosed. Each universal switch has at least three terminals and is switchable to connect any pair or all three terminals together. The plurality of interconnected universal switches are independently switchable to connect any one or more ports of the sparse matrix to any subset of the other ports. The sparse matrix may also be configurable to duplicate the connectivity of a variety of dimensionally different switch matrices by designating a first subset of the multiple ports as row ports and a second subset of the remaining ports as column ports with the added flexibility of connecting row-to-row and/or column-to column. The small physical size of signal stubs in the universal switches results in a signal path between any pair of terminals that may be suitable for the transmission of signal frequencies greater than approximately 500 mega-hertz.

摘要： A dimensionally flexible sparse matrix comprising multiple ports connected to a plurality of interconnected universal switches is disclosed. Each universal switch has at least three terminals and is switchable to connect any pair or all three terminals together. The plurality of interconnected universal switches are independently switchable to connect any one or more ports of the sparse matrix to any subset of the others ports. The sparse matrix may also be cofigurable to duplicate the connectivity of a variety of dimensionally different switch matrices by designating a first subset of the multiple ports as row ports and a second subset of the remaining ports as column ports with the added flexibilty of connecting row-to-row and/or column-to column. The small physical size of signals stubs in the univerals switches results in a signal path between any pair of terminals that may be suitable for the transmission of signal frequencies greater than approximately 500 mega-hertz.
