    • A system for cooling a data center includes a plurality of cooling racks, with each cooling rack including a housing and cooling system components supported by the housing. The system further includes a fluid communication system coupled to the cooling system components of the plurality of racks. The fluid communication system is configured to provide chilled coolant to and exhaust heated coolant from coolant system components of each cooling rack. The system also includes at least one controller coupled to each cooling rack of the plurality of cooling racks to control the operation of each cooling rack. The plurality of cooling racks and the fluid communication system are configured to be modular to allow placement of cooling racks in different locations in a row of equipment racks within the data center. Methods of cooling a data center are further disclosed.
    • 用于冷却数据中心的系统包括多个冷却架,每个冷却架包括由壳体支撑的壳体和冷却系统部件。 该系统还包括耦合到多个机架的冷却系统部件的流体连通系统。 流体通信系统被配置为向每个冷却架的冷却剂系统部件提供冷却的冷却剂并排出加热的冷却剂。 该系统还包括耦合到多个冷却架的每个冷却架的至少一个控制器,以控制每个冷却架的操作。 多个冷却架和流体通信系统被配置为模块化的,以允许将冷却架放置在数据中心内的一排设备机架中的不同位置。 进一步公开了冷却数据中心的方法。

    • A keyboard switch includes a plurality of spaced piezoelectric transducers secured to a common strike plate which is selectively impacted to actuate all of the transducers in response to switch actuation. The switch includes a snap action spring member carrying an impact member which impacts the strike plate as the spring member snaps to its actuated state when the switch is depressed . The spring member causes the impact member to maintain a compressive force against the strike plate, maintaining the transducers actuated while the key remains depressed and for a short interval after the key is released. An array of such switches on a keyboard is disposed over a plurality of parallel data lines which electrically contact one or more transducers at each switch in accordance with a switch indentification code. The parallel binary number appearing on the lines is received by processing circuitry which identifies each depressed key by its code. By maintaining compressive forces on the transducers, the system facilitates character processing and generation of certain specialized character functions.
    • 键盘开关包括固定到公共撞击板的多个间隔开的压电换能器,其被选择性地撞击以响应于开关致动来致动所有换能器。 该开关包括一个卡扣动作弹簧构件,该弹簧构件承受冲击构件,当冲击开关被按压时,该冲击构件随着弹簧构件卡入其致动状态而撞击冲击板。 弹簧构件使冲击构件保持抵抗撞击板的压缩力,当钥匙保持按压时,保持换能器的作用并且在钥匙被释放之后的短时间间隔内。 键盘上的这种开关的阵列设置在多​​个并行数据线上,该数据线根据开关识别码在每个开关处电接触一个或多个换能器。 出现在行上的并行二进制数由通过其代码识别每个按下的键的处理电路接收。 通过保持换能器上的压缩力,系统便于字符处理和产生某些专门的字符功能。
