    摘要： An electronic odor sensor is used in conjunction with a surgical tool, for example when wounds are cleansed to remove dead tissue and exudates, known clinically as debridement. The surgical tool will atomize substrate tissues and thereby mechanically generate vapors that can be sensed. Abrasion will likewise atomize substrate tissues liberating odors. Air near the surgical tool is collected and fed into the electronic odor sensor. The odor is analyzed by the sensor and a signal fed back based on the analysis.

    摘要： An image projection system comprises an image projector, such as a film or television projector and a projection screen. The projection screen is fabricated of a substantially transparent material, such as glass or plastic. The screen of transparent material has one or more areas or portions formed therein which areas or portions may be made to be translucent upon the application of a stimulus. Once in a translucent condition, the projected image can be received and viewed on the translucent portion. A mirror can be positioned behind the projection screen so that a person can view the reflection of themselves in the mirror when the screen is transparent, and an image can be projected when the projection screen is made to be substantially translucent.

    摘要： A sensor system issues measurement commands at a predetermined regular rate. If a measurement indicates that a gas of interest is present, then the sensor system is signaled to wake-up thereby pulsing a heater for the sensor element that improves the accuracy of measurements. Measurements of humidity, temperature and gas concentration are made. If the gas of interest is detected then the data is used to indicate a compensated gas measurement. The gas level is classified as to its hazard and an adaptive detection algorithm is used to set an activity mode. If the gas of interest is not detected, the adaptive detection algorithm is used to set a sleep mode that saves power. Measurement rates are kept constant while heater power is controlled to reduce power consumption. Measurement rates are changed to increase concentration sensitivity.

    摘要： A high voltage driver with capacitive coupling that is useful in the presence of the high power supply ripple common with higher-voltage systems. It permits extreme ranges of duty cycle, but without the limitations of transformer magnetics, or the increased complexity of optical coupling methods. It is also robust in the presence of voltage transients created by high-voltage arcing to the output drive-line.
