摘要： A flow sensor is provided having a substrate with a sensing element and flow channel aligned over the sensing element. The sensing element senses at least one property of a fluid. The flow channel is aligned by one or more guide elements formed in an alignment layer. The flow channel across the sensing area is accurately and precisely aligned due to the guide elements provided at the wafer-level, facilitating reliable, low-cost, and consistent results among multiple flow sensors. The flow sensor is adapted for use in harsh environments.

摘要： A flow sensor system includes a plurality of flow sensor chips, wherein each flow sensor chip among the plurality of flow sensor chips comprises a substrate, a heater element, a heater control circuit, and flow sensor component formed on the substrate, wherein the heater element is disposed separately from the heater control circuit on the substrate, wherein the heater control circuit is thermally isolated from the heater element and the flow sensor component. Additionally, an air gap can be formed between each sensor chip among the plurality of flow sensor chips, wherein the plurality of flow sensor chips comprises a flow sensor system in which each of the flow sensor chips are separated from one another by the air gap formed therebetween in order to reduce output distortion, response time, warm-up time, drift and noise associated with the plurality of flow sensor chips.

摘要： Methods and systems for actuating a negative rate switch. A negative rate switch comprising a plunger and a resilient actuator thereof can be provided, wherein a highest plunger force occurs at a free position and a lowest plunger force occurs at a full over travel position. The negative rate switch can be configured such that when the resilient actuator provides resilient actuating force to overcome a free position force associated with the free position, the plunger moves without interruption through a total range of travel thereof and when the resilient actuating force drops slightly below a full over-travel plunger force associated with the full over travel position, the negative rate switch overcomes the resilient actuating force to return the plunger to the free position thereof without interruption.
