US Patent:

6979409, Dec 27, 2005

Filed:

Feb 6, 2003

Appl. No.:

10/359067

Inventors:

Zhongmin Chen - Apex NC, US
Benjamin R. Smith - Raleigh NC, US
James W. Herchenroeder - Gaston IN, US

Assignee:

Magnequench, Inc. - Singapore

International Classification:

H01F001/057

US Classification:

252 6254, 148302, 420 83, 420121

Abstract:

The present invention relates to highly quenchable Fe-based rare earth magnetic materials that are made by rapid solidification process and exhibit good magnetic properties and thermal stability. More specifically, the invention relates to isotropic Nd—Fe—B type magnetic materials made from a rapid solidification process with a lower optimal wheel speed and a broader optimal wheel speed window than those used in producing conventional magnetic materials. The materials exhibit remanence (B) and intrinsic coercivity (H) values of between 7. 0 to 8. 5 kG and 6. 5 to 9. 9 kOe, respectively, at room temperature. The invention also relates to process of making the materials and to bonded magnets made from the magnetic materials, which are suitable for direct replacement of anisotropic sintered ferrites in many applications.

US Patent:

20040079445, Apr 29, 2004

Filed:

Oct 24, 2002

Appl. No.:

10/278843

Inventors:

Zhongmin Chen - Apex NC, US
Benjamin Smith - Raleigh NC, US

International Classification:

H01F001/057

US Classification:

148/101000, 148/302000

Abstract:

The present invention relates to magnetic materials made by rapid solidification processes which exhibit high remanence and intrinsic coercivity values and low flux-aging loss. More specifically, the invention relates to isotropic Nd—Fe—B type materials with remanence and intrinsic coercivity values of greater than 8.0 kG and 10.0 kOe, respectively, at room temperature, and bonded magnets made from the magnetic materials with low flux-aging loss and are suitable for high temperature applications. The invention also relates to methods of making the magnetic materials and the bonded magnets.

Filed:

Oct 9, 2018

Appl. No.:

16/154996

Inventors:

- Hopkinton MA, US
Benjamin S. Smith - Oakton VA, US

International Classification:

G06F 21/45
G06F 21/64

Abstract:

An authentication server in an illustrative embodiment is configured to communicate with one or more client devices over a network. Responsive to a successful login to a user account by a client device, the authentication server provides the client device with a login cookie for the user account for potential utilization in one or more subsequent logins to the user account. The authentication server initializes a cookie-specific counter for the login cookie, and increments the cookie-specific counter for each of one or more unsuccessful logins to the user account made utilizing the login cookie. Responsive to the cookie-specific counter reaching a specified value, the authentication server locks the user account for any subsequent logins to the user account made utilizing the login cookie. The authentication server resets the cookie-specific counter responsive to a successful login to the user account made utilizing the login cookie. The authentication server also maintains a non-cookie counter for counting failed logins made without utilizing a valid login cookie.

Abstract:

An agricultural machine includes a vibration stimulation source configured to generate a vibration stimulation signal directed toward plant matter and a sensor system configured to sense electromagnetic radiation reflected from the plant matter, generate a first signal based on the sensed electromagnetic radiation, and generate a second signal indicative of a resonant vibration response of the plant matter, that is in response to the vibration stimulation signal. The agricultural machine includes a plant evaluation system configured to, based on the first and second signals, generate plant characterization data indicative of one or more physical characteristics of the plant matter, and a control system configured to generate an action signal based on the plant characterization data.
