Abstract: An electronic device may be provided with control circuitry, wireless transceiver circuitry, and a display. The electronic device may be used to provide information to a user in response to being pointed at a particular object. The control circuitry may determine when the electronic device is pointed at a particular object using wireless control circuitry and/or motion sensor circuitry. In response to determining that the electronic device is pointed at a particular object, the control circuitry may take suitable action. This may include, for example, displaying information about an object when the electronic device is pointed at the object, displaying control icons for electronic equipment when the electronic device is pointed at the electronic equipment, and/or displaying a virtual object when the electronic device is pointed at real world object.

Abstract: A venous return catheter is provided having a first diameter distal portion suitable for insertion in a vena cava, a second, larger diameter proximal portion, and a transition portion forming a smooth transition between the first and second diameter portions. Drainage openings are provided in both the proximal and distal catheter portions. The catheter is of unitary construction, having a smooth bore through its entire length. It is also constructed from a soft, resilient material, but is reinforced with a harder, stiffer material in the region of the proximal drainage openings. The catheter may also be provided with wire reinforcement. The catheter is manufactured by a dip-molding process utilizing a male mandrel as a form.
