US Patent:

20020058435, May 16, 2002

Filed:

Oct 15, 2001

Appl. No.:

09/977879

Inventors:

Robert Williams - Chelmsford MA, US
Richard Plourde - Westminster MA, US

International Classification:

H01R003/00

US Classification:

439/165000

Abstract:

A high voltage electrical connection between a base unit and a panel display in a portable computer wherein the base unit and the panel display are pivotably secured to each other about a hinge axis, includes a flexible high voltage electrical conductor extending from the base unit to the panel display. A portion of the electrical conductor extends along the hinge axis such that pivoting of the panel display relative to the base unit causes said portion of the flexible conductor to twist about the hinge axis rather than actively bend.

Appl. No.:

9/309257

Inventors:

Amar G. Bose - Wayland MA
Richard G. Plourde - Ashland MA

Assignee:

Bose Corporation - Framingham MA

International Classification:

H03G 900

US Classification:

381102

Abstract:

An automatic dynamic equalization circuit has a potentiometer having a tap shunted by an active resonator circuit including a capacitor shunted by an active circuit presenting a high Q inductive reactance that is resonant at substantially 50 Hz and provides essentially no boost in the middle range of frequencies above 150 Hz with roll-off below about 45 Hz.
