A vehicle-mountable child protective device including a housing which is mountable onto a door of a vehicle and including a first housing portion, which is at least partially located within the vehicle when the device is mounted onto the vehicle and during device operation, and a second housing portion, which is at least partially located outside the vehicle when the device is mounted onto the vehicle and during device operation, a flag which is rotatably mounted via a flagpole onto the first housing portion and a flag positioning assembly at least partially within the first housing portion for automatically rotating the flag to a raised position outside of and above the vehicle upon opening of the door of the vehicle.

Technologies for an emergency evacuation system include a system operator and one or more emergency lighting units located in a building. Each emergency lighting unit further includes a processor, communication circuitry configured to communicate with the system operator, and a light indicator configured to be illuminated to indicate an exit of the building.

A method for identifying a mechanical impedance of an electromagnetic load may include generating a waveform signal for driving an electromagnetic load, the waveform signal comprising a first tone at a first driving frequency and a second tone at a second driving frequency. The method may also include during driving of the electromagnetic load by the waveform signal or a signal derived therefrom, receiving a current signal representative of a current associated with the electromagnetic load and a back electromotive force signal representative of a back electromotive force associated with the electromagnetic load. The method may further include determining amplitude and phase information of the current signal responsive to the first tone and second tone, determining amplitude and phase information of the back electromotive force signal responsive to the first tone and second tone, and identifying parameters of the mechanical impedance of the electromagnetic load based on the amplitude and phase information of the current signal and the amplitude and phase information of the back electromotive force signal.

An emotional care apparatus based on a sound and a method thereof are provided. The emotional care apparatus includes a sound output device that outputs a sound to speakers and a processor electrically connected with the sound output device. The processor selects an emotional care mode, separates a sound source for each instrument from music content based on the emotional care mode, distributes the sound source for each instrument to the speakers, and controls the sound output device to play and output the sound source for each instrument to the distributed speakers.
