US Patent:

54654599, Nov 14, 1995

Filed:

Jan 28, 1994

Appl. No.:

8/188502

Inventors:

David M. Hopkins - San Francisco CA

International Classification:

A47G 2704

US Classification:

16 11

Abstract:

A device for fastening carpet covering to stairways. A prefabricated strip fastener of plastic or similar material preformed or capable of being formed in the field to have two legs and fixedly positioned on its legs, tackless holding pins for carpets and adapted for automatic stapling or nailing into the crotch of a stairway for receiving the carpet covering.

Appl. No.:

17/306870

Inventors:

- Redwood City CA, US
Anatoly Yakovlev - San Francisco CA, US
Ji Eun Jang - Foster City CA, US
Hesam Fathi Moghadam - Sunnyvale CA, US
David Hopkins - Carson City NV, US

International Classification:

H01L 23/64
H01L 23/522
H01L 23/00
H02M 3/158
G05F 1/46
H02M 1/14

Abstract:

Distributions of on-chip inductors for monolithic voltage regulation are described. On-chip voltage regulation may be provided by integrated voltage regulators (IVRs), such as a buck converter with integrated inductors. On-chip inductors may be placed to ensure optimal voltage regulation for high power density applications. With this technology, integrated circuits may have many independent voltage domains for fine-grained dynamic voltage and frequency scaling that allows for higher overall power efficiency for the system.
