Abstract: Systems, devices, and methods for segmenting musical compositions are described. Discrete, musically-coherent segments (such as intro, verse, chorus, bridge, solo, and the like) of a musical composition are identified. Distance measures are used to evaluate whether each bar of a musical composition is more like the bars that directly precede it or more like the bars that directly succeed it, and each respective series of musically similar bars is assigned to the same respective segment. Large changes in the distance measure(s) between adjacent bars may be used to identify boundaries between abutting musical segments. Computer systems and computer program products for implementing segmentation are also described. The results of segmentation may advantageously be applied in computer-based composition of music and musical variations, as well as in other applications involving labelling, characterizing, or otherwise processing music.

Abstract: In an embodiment, a door detection system may include a transmitter, a receiver, a reflector, and one or more processors. The transmitter positioned on an elevator car door transmits a signal towards a reflector on a hoistway door and the reflector reflects the signal towards the receiver when the hoistway door is properly positioned with respect to the elevator door. The one or more processors determine whether the hoistway door is properly positioned with respect to the elevator car door based on the reflected signal received by the receiver. If the hoistway door is not properly positioned, the elevator car is prevented from moving. If the hoistway door is properly positioned, the elevator car is free to move.
