Embodiment Construction

[0012] figure 1 A basic example is shown in . The power transmitter assembly 100 receives power from a source (eg, AC plug 102). The frequency generator 104 is used to couple energy to the antenna 110 (here, a resonant antenna). Antenna 110 includes an inductive loop 111 that is inductively coupled to a high-Q resonant antenna portion 112 . The resonant antenna comprises N number of coil loops 113, each loop having a radius R A . A capacitor 114 (shown here as a variable capacitor) is connected in series with the coil 113, forming a resonant tank. In the described embodiment, the capacitor is a completely separate structure from the coil, but in some embodiments the self-capacitance of the wires forming the coil may form capacitance 114 .

[0013] Frequency generator 104 may preferably be tuned to antenna 110, and also selected for FCC compliance.

[0014] This embodiment uses a multi-directional antenna. 115 shows the energy output in all directions. Antenna 100 is no...

Abstract

Retinal stem cells haying embryonic-like characteristics are disclosed. The retinal stem cells express one or more of the embryonic stem cell markers Nanog and OCT-4. The retinal stem cells may be obtained from retinal pigment epithelium. Methods of making and using retinal stem cells are also disclosed.

Description

[0001] This case is a divisional application of the patent application titled "Remote Low Frequency Resonator and Materials", the filing date is August 11, 2008, the application number is 200880102575.7, and the priority date is August 13, 2007. [0002] This application claims priority to Provisional Application No. 60 / 955,598, filed August 13, 2007, which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates to remote low frequency resonators and materials. Background technique [0004] It is desirable to transfer electrical energy from a source to a destination without using wires to direct the electromagnetic field. Difficulties with previous attempts have been low efficiency coupled with insufficient amounts of delivered power. [0005] Wireless power transfer is described in our prior and provisional applications including, but not limited to, Serial No. 12, filed January 22, 2008, entitled "Wireless Apparatus and ...
