The subject intradermal delivery device provides for penetration to a fixed depth without requiring special expertise by the user. The device consists of a syringe nested inside an inner shell and an outer shell. An elongated annular channel is formed between the inner shell and the outer shell. A housing receives the syringe and concentric shells in a sliding engagement. A first seal on the distal end of the housing forms a variable length channel in communication with the elongated annular channel via a port formed in the outer shell. When the device is applied to the skin, the housing and syringe are slid towards the skin, and the variable length channel generates a vacuum which forces the skin to bulge into the elongated annular channel. As a result, the skin is tensioned across the inner shell to form a substantially planar, taut target area of skin. The taut target area of skin in combination with a stop on the housing determines the insertion depth of the syringe.

An objective function and a constraint expression are established by a scheme of the invention as conditions for selecting advertisement information to be inserted into a slot in a content. The objective function is used to maximize a total of cost values held by the advertisements selected to be inserted into slots.

The objective function and constraint expression making up the selection conditions are solved as a mathematical programming assignment problem, whereby advertisement information is selected for insertion into predetermined slots in a manner maximizing the benefits of the parties participating in the scheme. In a setup of moving picture streaming distribution, the scheme allows suitable advertisement information to be inserted selectively into slots of contents.

An apparatus and method for mounting a valve stem to the rim of an automotive vehicle wheel includes rims being supplied in series by a conveyor to a gauging station where the type and / or size of the rim and the location and alignment of an aperture for receiving the valve stem is determined by a machine vision system. An electronic control system directs a robotic manipulator to grasp either the valve stem or the rim, move the valve stem or the rim to a mounting station, position the valve stem or the rim with respect to the other such that the aperture in the rim is in coaxial alignment with the valve stem, and insert the valve stem through the aperture in the rim. If necessary, a power-actuated nut runner, mounted on the robotic manipulator or adjacent the mounting station, is used to tighten a nut over the valve stem. As an alternative to the machine vision system, the gauging station can use a rotating table which rotates the wheel about a central axis, and an “electric eye” optical sensor directing a beam of infrared light onto the rim. As the rim rotates through the beam, the presence or lack of a reflection of the light beam is used to detect the location of the aperture, and rotation of the table is stopped when the aperture is in alignment with the beam. A probe mounted on the gauging station can be extended to project into the aperture to confirm that the aperture is at the desired position and reposition the rim slightly to provide a precise positioning of the aperture.
