Abstract: Speakers (e.g. “loudspeakers”) from different manufactures may have differing characteristics. In order to improve audio performance, an audio system may customize audio settings based on characteristics of an attached speaker. Described is a technique for determining speaker characteristics by sending a signal through a filter of the attached speaker. The signal may be a probing signal that produces no audible effect from the speaker. The signal may progress through one or more frequency ranges and an impedance signature may be measured. When the signal progresses through a frequency range, the impedance may be measured and a speaker model type and/or characteristics or condition of the speaker may be determined based on the measured impedance.

Abstract: Doors such as garage doors can be automated by pushing commands to a removable device attached to the garage door. The state of the door (e.g. whether the door is open or closed) may be obtained from a position sensor located within a removable device. An implementation may indicate, over a wireless network, the state of the door to a user. The user may send a command to a wireless transmitter located within the device to change the state of the door. An implementation may also send a signal to the door to change the state of the door.
