a control apparatus including a module being positioned to lie over the bed and having at least one input on the module activated directly by a patient on the bed to perform at least one function and an arm having a first end coupled to the module and a second end coupled at the head end edge so that the module and arm move with the head end, the arm being an articulating arm, the articulating arm including a first arm segment having a first end coupled to the head end of the bed and a second end, a second arm segment having a first end and a second end, a first articulating joint coupled to the first end of the first arm segment and to the head end of the bed, and a second articulating joint coupled to the second end of the first arm segment and the first end of the second arm segment, the control apparatus further including a securing mechanism configured to couple the articulating arm to the head end of the bed, and the securing mechanism including an adjustable clamp having first and second clamping portions which each surround a portion of the first articulating joint and an adjustment mechanism configured to provide relative movement between the first and second clamping portions to adjust the pressure applied by the adjustable clamp to the first articulating joint.

105. The bed assembly of claim 104, wherein the first articulating joint has a larger diameter than the first end of the articulating arm to provide a larger clamping surface area to reduce the clamping force required by the adjustable clamp.
