The current source and voltage sensor are configured to maintain a constant resistance of the conductor between the first set of pins. | 07-14-2011 |
| 20130025363 | Thermal Type Flow Rate Sensor - To reduce a signal variation of a bridge circuit connected with a temperature sensing resistor that is caused by a strain even when the strain is generated at a diaphragm portion of a substrate installed with a heater resistor and the temperature sensing resistor. In a thermal type flow rate resistor including a substrate, a diaphragm | 01-31-2013 |
| 20140311237 | METHOD FOR DETECTING A FLOW PROPERTY OF A FLOWING FLUID MEDIUM - A method for detecting at least one flow property of a flowing fluid medium, at least one sensor element being used. The sensor element includes at least one heating element and at least two temperature measuring sensors. At least one first measured variable and at least one second measured variable, which is different from the first measured variable, are detected with the aid of the sensor element. The first measured variable and the second measured variable may be influenced by the flow property. At least one correction, in particular at least one correction factor and/or at least one correction vector, is generated from the first measured variable and the second measured variable. The flow property is determined from the first measured variable and the second measured variable under consideration of the correction. | 10-23-2014 |
| 20140352424 | AIRFLOW MEASURING APPARATUS - Airflow measuring apparatus compring: sub-passage that takes in part of flow of fluid flowing through an intake pipe; sensor element that is disposed in the sub-passage to measure the flow of fluid; a circuit part that converts the flow of fluid detected by the sensor element into an electric signal; connector part connected to the circuit part to output a signal externally; and casing that supports the sensor element and the circuit part, the sensor element being disposed in the intake pipe. The sensor element includes a cavity disposed at a semiconductor substrate, a diaphragm including a thin film part that covers the cavity. The sensor element on a lead frame have surfaces that are mold-packaged with resin so that a diaphragm of the sensor element and part of the lead frame are exposed. One hole is disposed at the lead frame for communication between the cavity and exterior. | 12-04-2014 |

| 20090100924 | Fluid Flow Rate Sensor And Method Of Operation - A fluid flow rate sensor includes a detection circuit which generates a first signal corresponding to an output voltage of a bridge circuit, and a second signal corresponding to a fluid temperature. A control module can more accurately and quickly determine the fluid flow rate based on the first signal, the second signal and a look-up table. The look-up table includes a plurality of curves plotted according to data, indicating relationship among the fluid temperature, the output voltage and the fluid flow rate. The fluid flow rate sensor is inherently temperature compensated and has a shorter response time. | 04-23-2009 |
