Patent number: 8502630Abstract: An improved field emission system and method. The invention pertains to field emission structures comprising electric or magnetic field sources having magnitudes, polarities, and positions corresponding to a desired spatial force function where a spatial force is created based upon the relative alignment of the field emission structures and the spatial force function. The spatial force function may be based on one or more codes. In various embodiments, the code may be modified or varied. The code may be combined with another code. One or more aspects of the code, including spacing and amplitude, may be modulated or dithered according to a predefined pattern. Multiple magnet arrays may be combined, each based on a different code or portion of a code, resulting in a combination spatial force function. Magnet structures having differing field patterns may be used to generate a desired spatial force function related to a cross correlation of the two field patterns.Type: GrantFiled: February 5, 2013Date of Patent: August 6, 2013Assignee: Correlated Magnetics Research LLCInventors: James Lee Richards, Ryan R.

Patent number: 8314671Abstract: A key system for enabling operation of a device. The key system is based on magnets arranged according to one or more codes. The codes may act as a unique identifier or key, requiring a matching part to operate the device. Thus, the code can act like a key that will only achieve lock when matched with a like (complementary) pattern. The codes may be from a set of codes having low cross correlation among codes in the set, for example Kasami codes or Gold codes.Type: GrantFiled: January 16, 2012Date of Patent: November 20, 2012Assignee: Correlated Magnetics Research LLCInventors: Larry W.

Patent number: 8174155Abstract: The present invention relates to a stepping motor with a magnet pole pattern having a predetermined pattern around the circumference of the stepping motor. In one embodiment, the pattern relates to a code having a unique single maximum autocorrelation peak over the period of the code. Example codes include Barker codes, PN codes, Kasami codes, Golomb ruler codes, and other codes. In one embodiment, the rotor and stator have a matching pole pattern. In one embodiment, the drive is arranged to align the poles in an inline configuration, alternatively, the drive may be arranged to align the poles in a diagonal configuration. In a further embodiment, one or more sets of poles are provided on the stator, each set being offset rotationally by a partial pole spacing. In one embodiment, the rotor is initially synchronized with the stator by capturing the rotor using a single unambiguous lock-in position based on the code autocorrelation.Type: GrantFiled: October 11, 2011Date of Patent: May 8, 2012Assignee: Correlated Magnetics Research LLCInventors: Larry W.
