    There is a post in pbalien73 pg 14, referring to a copy of NUTS and VOLTS magazine , which discuses pro & con of different short range detection methods.

    Purely based on my uneducated guess in this field, I would say:

    - Ultrasound can detect better but with less focus
    - Infrared is more likely to be perturbed by the environment but can be focused

    I imagine infrared would be cheaper? Ultrasound transducers can be pricey can't they?
