Abstract: A level shifter includes a latch having first and second branches, first and second outputs, first and second control switches in series between the respective branches and outputs, and a controller receiving first and second output signals and outputting first and second control signals to the first and second control switches for controlling activation thereof. In an initial state, the first output signal is in the first state, the first control switch is activated, the second output signal is in the second state, and the second control switch is deactivated. In a final state, the first output signal is in the second state, the first control switch is deactivated, the second output signal is in the first state, and the second control switch is activated. The controller changes the first and second control signals only after the first and second output signals reach the respective second and first states.

Abstract: In an infusion pump operable to deliver fluid to a patient at a programmed therapy flow rate, air-in-line sensing is improved by commanding the pumping mechanism to deliver a bolus volume of fluid at a flow rate higher than the therapy flow rate when an uninterrupted volume of air is detected that exceeds a first threshold. In many cases, the bolus will be effective to clear microbubbles from an observation zone of the air-in-line sensor to avoid an air-in-line alarm condition. If the uninterrupted volume of air continues to grow beyond a second threshold in spite of the bolus, then an alarm may be triggered. The invention reduces false alarms.
Abstract translation: 在可操作以以编程的治疗流速将流体递送到患者的输液泵中，通过指示泵送机构以高于治疗流量的流速输送推注体积的流体来改善流体内感测， 检测到超过第一阈值的不间断体积的空气。 在许多情况下，推注将有效地从空气在线传感器的观察区域清除微泡，以避免空中在线警报状况。 如果不间断的空气量继续增长超过第二阈值，尽管大量推注，则可能会触发报警。 本发明减少了误报。

Abstract: Threshold detection for load current on a bus involves generating an output current representative of the load current using a transconductance circuit, sampling the output current during a quiescent phase of the bus to produce a sample current, generating a compensation current that is proportional to the transconductance gain associated with the transconductance circuit, where the compensation current is a function of the sample current, combining the output current, the sample current, the compensation current, and a reference current representative of a threshold value for the load current to produce a combined current, and using a discriminator during an active phase of the bus to output a first value when the sum current exceeds the threshold value and a second value when the combined current is less than the threshold value.
Abstract translation: 总线上负载电流的阈值检测包括使用跨导电路产生代表负载电流的输出电流，在总线的静止阶段对输出电流进行采样以产生采样电流，产生与跨导成比例的补偿电流 与跨导电路相关联的增益，其中补偿电流是采样电流的函数，组合输出电流，采样电流，补偿电流和代表负载电流的阈值的参考电流以产生组合电流 并且当总和电流超过阈值时，在总线的有效相位期间使用鉴别器输出第一值，当组合电流小于阈值时，输出第二值。
