1. A patient support apparatus comprising:
- a base frame;
an elevating frame disposed in spaced relation to said base frame;
a lifting device configured to move said elevating frame relative to said base frame;
an emitter coupled to one of said base frame and said elevating frame, said emitter being configured to generate a wireless signal, wherein said wireless signal generated by said emitter comprises an infrared light optical curtain positioned intermediate said base frame and said elevating frame; and
a receiver coupled to one of said base frame and said elevating frame, said receiver associated with said emitter and configured to detect said wireless signal.

11. A hospital bed comprising:
- a first component;
a second component configured to move relative to said first component along a path of travel;
an emitter, wherein said emitter generates an infrared light optical curtain positioned intermediate said first component and said second component;
a detector supported by one of said first component and said second component, said detector configured to detect an obstacle that is within said path of travel of said second component and that breaches the optical curtain without the obstacle contacting the detector, said detector configured to provide a control signal in response to detecting the obstacle; and
a control unit in communication with said detector and configured to prevent relative movement of said first and second components in response to said control signal. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
