US Patent:

20080230006, Sep 25, 2008

Filed:

Mar 19, 2007

Appl. No.:

11/688080

Inventors:

David R. Kirchoff - Brooklyn Park MN, US
Michael S. Erickson - Cedar MN, US

Assignee:

THE WALMAN OPTICAL COMPANY - Minneapolis MN

International Classification:

B05C 11/00

US Classification:

118695

Abstract:

A shaft assembly of a lens coating system includes a first portion reversibly engagable with a second portion. A reciprocating drive disengages and subsequently re-engages the shaft first and second portions. A lens holder is coupled to an arm, which is coupled to the shaft first portion. Another drive, coupled to the shaft second portion, rotates the arm about an axis of the shaft assembly, when the first and second portions are engaged, such that the lens holder travels along a pathway surrounding the assembly. The system includes a plurality of stations, each station having an opening along the pathway, so that the rotating drive may transfer the lens holder into proximity with each station, when the shaft first and second portions are engaged, and the reciprocating drive may transfer a lens, held by the lens holder, into and out from each station through the opening thereof.

Abstract:

A wireless location assisted zone guidance system incorporates dynamically variable intervals between sequential position requests. Variables used to influence the duration of a current interval between sequential position requests include: location within a current zone; displacement rate within a zone; and output from sensors such as secondary low power location sensors, inertial sensors, and biometric sensors. Preferably, the sensors are not being used to try to determine precise position, but instead to indicate a degree of uncertainty in the current position. When this degree of uncertainty is sufficient to merit added processing and associated energy consumption, a new wireless location determination will be made.

Abstract:

A look-up table is defined by at least one reference point, and rows and columns that are offset from the reference. The table rows and columns correspond to ordinate and abscissa data points representing geographic locations. Each data point offset in the table corresponds to a predefined geographic offset. The look-up table contains machine-stored values at each table location, with each value representing a particular one of several guidance zones. The real-time determination of the guidance zone is made by first determining present location using GPS or other wireless location signals. The corresponding table location is identified by calculating latitudinal and longitudinal offsets from a reference point, and using these offsets as the two indices to access a double-indexed array. The value retrieved from the indexed array identifies the guidance zone. Each guidance zone has an associated set of characteristics used to provide behavioral guidance to an animal.
