Abstract: Emission of a scented substance, which is mixed with a tracer substance, is controlled based on an amount of the tracer substance sensed during the emission of the scented substance. The scented substance can be mixed with the tracer substance in a known defined ratio. When the mixture of the scented substance and tracer substance is being emitted by a device, a substance sensor component can sense the amount of the tracer substance being emitted. An emission management component can control the emission of the mixture of substances based on the amount of the tracer substance detected to facilitate controlling the amount of the scented substance being emitted. The emission management component also can control emission of the scented substance in a defined area based on the tracer substance and environmental conditions in the defined area. The tracer substance can be safe, colorless, and/or odorless with respect to people.

Abstract: Techniques provided for using hardware and software to modify a mobile device to improve the safety and awareness of a user to their environmental surroundings. One embodiment of the invention is to update mobile device applications to include live video using the built in rear camera of area ahead of the user as background image. Rear camera would normally be viewing ground, so an embodiment includes a custom case or other attachment to the mobile device with a mirror to allow rear camera to view area ahead. The case or attachment positions the mirror relative to the camera and has an adjustable angle to achieve the correct field of view for the way (or posture) the user is holding the mobile device.

Abstract: Various embodiments provide for an acoustically configurable microphone device that can adjust various parameters affecting sensitivity, acoustic overload point, signal to noise ratio, sample rate, and other parametric choices that affect the performance and function of the acoustic sensor based on commands received via acoustic communications. An acoustic analysis engine can analyze acoustic communications received to determine whether or not the acoustic communication contains a command associated with configuring the microphone. If the acoustic communication is determined to contain a configuration command, a controller on the microphone can implement the configuration command. The acoustic communications can be at ultrasonic frequencies in some embodiments so that the acoustic communications are outside the range of human hearing.

Abstract: An electronic device may be provided with an electronic compass. The electronic compass may include magnetic sensors. The magnetic sensors may include thin-film magnetic sensor elements such as giant magnetoresistance sensor elements. Magnetic flux concentrators may be used to guide magnetic fields through the sensor elements. To reduce offset in the electronic compass, the magnetic flux concentrators may be demagnetized by applying a current to a coil in the housing. The coil may be formed from loops of metal traces within a printed circuit or other loops of conductive paths. Magnetic flux concentrators may have ring shapes. A ring-shaped magnetic flux concentrator may be formed from multiple thin stacked layers of soft magnetic material separated by non-magnetic material.
