(BBC News) The firm that designed the sensors on the Uber self-driving car that killed a woman this week has said its technology was not to blame.
San Jose-based Velodyne told the BBC it was "baffled" by the incident, adding its equipment was capable of seeing in the dark.
Elaine Herzberg, 49, was struck by the car late on Sunday night in Tempe, Arizona. She died in hospital.

The investigation into what caused her death is ongoing.
Video of the incident was published by investigators earlier on Wednesday. It showed Ms Herzberg walking with her bicycle, away from a pedestrian crossing. Neither the car - nor its human driver - reacted.
