Abstract: A power system provides power from a power source to a load via a distribution bus, and includes a DC-DC converter coupled in parallel with a network of switching elements coupled between an output terminal of the power source and the distribution bus. A controller is configured to selectively activate or deactivate the DC-DC converter and each of the switching elements to enable the power source to power the load via the distribution bus. The switching elements may be transistors, and the diodes may be parasitic body diodes of the transistors. The power source may be a battery, such as a rechargeable battery. An output voltage level from the battery may be regulated by the controller as a function of operation of the DC-DC converter and a number of the activated or deactivated transistors.

Abstract: Embodiments of the disclosure provide systems and methods for estimating battery discharge time duration during high-rate battery discharging. Generally speaking, embodiments of the present disclosure are directed to a prediction of battery run times for short duration, high-current discharge events that are scaled in seconds rather than minutes, and which are continuously compensated for ambient temperature which can alter discharge times as a result of reaching thermal limitations before chemical capacity has actually been exhausted.

Abstract: 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.

Abstract: 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.
