20120167392 | RAZOR WITH CHEMICAL AND BIOLOGICAL SENSOR - A razor has an electrochemical sensor for sensing various characteristics, such as biological, chemical, temperature, humidity, and pressure. The electrochemical sensor is positioned within a razor head of the razor, but may be attached to and enclosed in the razor head housing or attached to a razor blade of the razor. The electrochemical sensor may be positioned at different locations within the housing and on the razor blades. The electrochemical sensor may be positioned such that a sensing surface is exposed to a shaving surface of a patient. The razor may also have various electrical components for processing signals generated by the electrochemical sensor and determining the presence or concentration of a chemical or biological marker. The data associated with the signals may be displayed, transmitted to a separate computing device, or stored in a memory. | 07-05-2012 |

20130010826 | MICROSENSOR WITH INTEGRATED TEMPERATURE CONTROL - Microsensors that include an integrated thermal energy source and an integrated temperature sensor are capable of providing localized heating and temperature control of individual sensing regions within the microsensor. Localized temperature control allows analyte detection to be carried out at the same temperatures or substantially the same temperatures at which the sensor is calibrated. By carrying out the sensing near the calibration temperature, more accurate results can be obtained. In addition, the temperature of the sensing region can be controlled so that chemical reactions involving the analyte in the sensing region occur near their peak reaction rate. Carrying out the sensing near the peak reaction rate improves the sensitivity of the sensor which is important as sensor dimensions decrease and the magnitude of the generated signals decreases. | 01-10-2013 |

20140291677 | INTEGRATED MULTI-SENSOR MODULE - A semiconductor-based multi-sensor module integrates miniature temperature, pressure, and humidity sensors onto a single substrate. Pressure and humidity sensors can be implemented as capacitive thin film sensors, while the temperature sensor is implemented as a precision miniature Wheatstone bridge. Such multi-sensor modules can be used as building blocks in application-specific integrated circuits (ASICs). Furthermore, the multi-sensor module can be built on top of existing circuitry that can be used to process signals from the sensors. An integrated multi-sensor module that uses differential sensors can measure a variety of localized ambient environmental conditions substantially simultaneously, and with a high level of precision. The multi-sensor module also features an integrated heater that can be used to calibrate or to adjust the sensors, either automatically or as needed. Such a miniature integrated multi-sensor module that features low power consumption can be used in medical monitoring and mobile computing, including smart phone applications. | 10-02-2014 |

One or more such multi-sensor modules can be used as building blocks in dedicated application-specific integrated circuits (ASICs) for use in environmental control appliances that rely on measurements of air flow. Furthermore, the sensor module can be built on top of existing circuitry that can be used to process signals from the sensors. By integrating the Venturi chamber with accompanying environmental sensors, correction factors can be obtained and applied to compensate for temporal humidity fluctuations and spatial temperature variation using the Venturi apparatus. | 10-02-2014 |
