US Patent:

54566045, Oct 10, 1995

Filed:

Oct 20, 1993

Appl. No.:

8/139553

Inventors:

Robert A. Olmsted - Minnetonka MN
Jonathan C. Rice - St. Paul MN

International Classification:

G09B 904
G09B 1916

US Classification:

434 62

Abstract:

A method and apparatus for controlling model vehicles in a manner which accurately simulates the operation of real vehicles. Parameters relating to operational characteristics of a vehicle, environmental conditions, loading conditions, operator control settings, and physical characteristics of a controllable model are processed by a computer to determine appropriate control functions to a model allowing it to accurately replicate the operation of a real vehicle operating under the same set of conditions.

Assignee:

Secure Computing Corporation - Roseville MN

International Classification:

H04L 902

US Classification:

380 21

Abstract:

A data communication system providing for the secure transfer and sharing of data via a local area network and/or a wide area network. The system includes a secure processing unit which communicates with a personal keying device and a crypto media controller attached to a user's Workstation. The communication between these processing elements generates a variety of data elements including keys, identifiers, and attributes. The data elements are used to identify and authenticate the user, assign user security access rights and privileges, and assign media and device attributes to a data access device according to a predefined security policy. The data elements are manipulated, combined, protected, and distributed through the network to the appropriate data access devices, which prevents the user from obtaining unauthorized data.

Filed:

Appl. No.:

6/439372

Inventors:

Robert W. Olmsted - Butler PA
Joseph F. Huth - Butler PA

Assignee:

Spang Industries Inc. - Butler PA

International Classification:

H01F 2106
H01F 4102

US Classification:

336 83

Abstract:

New ferrite pot core type products and fabrication methods are disclosed for production and assembly of tunable-inductance magnetically-soft ferrite devices. Unitary helical threads formed within the central opening of a ferrite pot core element provide controlled axial movement of a non-threaded male tuning member, carrying a ferrite rod, to adjust the air gap between spaced center posts of an assembled pair of pot core elements. Thread matching and registry requirements are eliminated by such unitary thread means which present either helical path die means, for cutting threads in a cylindrical nonmagnetic portion of a male tuning member or, circumferentially continuous helical threads, which deform nonmagnetic protrusions uniformly distributed about the periphery of a noncircular cross section nonmagnetic portion of a male tuning member during rotation of a male tuning member within a core element central opening.

Appl. No.:

Spang & Company - Butler PA

International Classification:

H01F 1502
H01F 2106

US Classification:

336 83

Abstract:

New ferrite tuning assemblies are disclosed in which a unitary ferrite shaft is covered with a nonmagnetic material to provide a peripheral working surface for coacting with unitary helical thread means in the central opening of a core element to provide axial movement, for air gap adjustment purposes, by cutting and/or deforming at least a portion of the peripheral working surface of the tuning member. Various longitudinal and transverse cross-sectional configurations for the integral male tuning member are made available by the fabrication and assembly methods taught; assembly of inductance-tunable ferrite devices is facilitated by enabling insertion of a male tuning member into the central opening of either core element in an assembly and tuning from either longitudinal end of the aligned central openings.
