Methods and an apparatus allow a child to be securely carried on a adult's shoulder's while allowing the adult substantial freedom of movement and free use of hands and arms. An embodiment comprises two ankle cuffs, each securely holding one of the child's ankles and a torso strap connected thereto for securing the child's ankles to the torso of the wearer.

Method and apparatus for securing a child

The invention provides methods of nanolithography and products therefor and produced thereby. In particular, the invention provides a nanolithographic method referred to as high force nanografting (HFN). HFN utilizes a tip (e.g., a scanning probe microscope (SPM) tip such as an atomic force microscope (AFM) tip) to pattern a substrate passivated with a resist. In the presence of a patterning compound, the tip is used to apply a high force to the substrate to remove molecules of the resist from the substrate, whereupon molecules of the patterning compound are able to attach to the substrate the form the desired pattern.

Nanolithography methods and products therefor and produced thereby

An enhanced scanning probe microscope is provided with means for controlling the atmosphere surrounding the probe tip and the sample or surface to be scanned. Additional enhancements include a tip holder which can be tuned to reflect the laser light of the apparatus on the photodiode, a brace to stabilize the optical microscope relative to the sample and a mirror placed to allow visualization of the sample and tip from the side. Also provided is an enhanced method of nanolithography using an enhanced scanning probe microscope in which it is possible to control the atmosphere surrounding the probe tip and the substrate to be patterned or etched.
