| 20120112865 | Key System For Enabling Operation Of A Device - 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. | 05-10-2012 |
| 20120091847 | ELECTROMAGNETIC STRUCTURE HAVING A CORE ELEMENT THAT EXTENDS MAGNETIC COUPLING AROUND OPPOSING SURFACES OF A CIRCULAR MAGNETIC STRUCTURE - An electromagnetic structure comprises a rotor assembly having at least one circular magnetic structure. The structure has opposing first and second surfaces that extend around a peripheral boundary region. A plurality of emission regions are disposed along said peripheral boundary region, with each emission region presenting poles having opposite polarities of a first polarity and a second polarity on the opposing first and second surfaces of the circular magnetic structure. Adjacent emission regions have alternating pole orientations such that each emission source having the first polarity is between two emission sources having the second polarity and each emission source having the second polarity is between two emission sources having the first polarity. A rotational element rotates the at least one circular magnetic structure about a rotation axis that is perpendicular to the opposing first and second surfaces. | 04-19-2012 |
| 20120026843 | Stepping motor with a coded pole pattern - 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. | 02-02-2012 |
