Abstract: A method and apparatus are provided for creating a referral network for member physicians utilizing the Internet. The referral network provides its members an organized and efficient system for generating and storing patient referrals. To become a member of the referral network, a physician registers with the referral network web site. A member physician generates a patient referral document using referral network software on the referral network web site. The patient referral document is sent to another physician to refer a patient to the physician. If the recipient physician is not a member of the referral network, the patient referral document includes a promotion for the referral network to induce the physician receiving the referral document to become a member of the referral network.

Abstract: A nano-liquid crystal on silicon (nano-LCoS) chip having carbon nanotube (CNT) pillars that are grown on a glass substrate thereof. As the heights of the CNT pillars are uniform, the CNT pillars can function as spacers providing a uniform cell gap between the glass substrate and a silicon chip of the nano-LCoS chip. Also, being excellent electrical conductors, CNT pillars can form a part of the electrical connection between an outside voltage source and the indium tin oxide (ITO) layer formed on the glass substrate. The nano-LCoS chip includes nano-LCoS alignment keys that are formed in the silicon chip and connected to the CNT pillars. By applying the same voltage to the ITO layer and keys, a portion of the liquid crystal activated by the keys become transparent fiduciary marks for optical alignment of nano-LCoS chips.
