Abstract: A system and method are disclosed relating to a pipeline for generating a computer model of a target user, including a hand model of the user's hands and fingers, captured by an image sensor in a NUI system. The computer model represents a best estimate of the position and orientation of a user's hand or hands. The generated hand model may be used by a gaming or other application to determine such things as user gestures and control actions.

Abstract: In combination, a removable tool may be selectively attached to the cleaning wand of a carpet extractor to alternatively clean hard surfaced floors, such as grouted tile and when not attached, clean carpeted floors. The removable tool may be sold as an aftermarket item for existing carpet extractors. A method of using the carpet extractor with the removable tool allows the apparatus to fulfill dual purposes, e.g., cleaning hard surfaced floors and when the tool is attached to the cleaning wand, and when the tool is removed from the wand to clean carpeted floors.

Abstract: A system for monitoring carbon monoxide in an environment which includes an apparatus emitting carbon monoxide, such as an internal combustion engine. A carbon monoxide sensor measures a concentration of carbon monoxide in the environment and provides an electrical signal to a processor that is representative of the measured concentration of carbon monoxide. The processor determines the concentration of carbon monoxide corresponding to the electrical signal, provides an output signal at or above predetermined carbon monoxide concentration thresholds, calculates an estimated carboxyhemoglobin level for the operator corresponding to the carbon monoxide concentrations calculated over time, and provides an output signal at or above predetermined carboxyhemoglobin thresholds. The signals are then received by one or more devices which provide textual, visual, and/or audible warnings indicating that environmental concentrations of carbon monoxide have caused a predetermined warning threshold to be met or exceeded.
