Filed:

Jan 18, 2001

Appl. No.:

09/765181

Inventors:

Jeff C. Hawkins - Redwood City CA
John J. Daly - San Carlos CA

Assignee:

AST Research, Inc. - Irvine CA

International Classification:

G06F 116

US Classification:

708100, 361681, 345169

Abstract:

A portable lightweight combination laptop and pad computer has a display mounted on a main housing for movement between a closed position and an open position. In the closed position, a keyboard is covered by the undersurface of the display and the display viewing surface remains visible so that the computer may be used in the pad mode with a conductive stylus for data and command entry. In the open position, the keyboard is exposed so that the computer may be used in a laptop or desk top mode, or in a combined mode including the pad mode. The display is mounted to the housing by a four bar hinge mechanism, and a pair of latches are provided approximately mid-way between the front and rear portions of the housing along the side margins to securely latch the display in the closed position for storage, transit or use in the pad mode. A removable power pack, which attaches to the rear of the housing, carries battery power and a charging circuit for supplying power to the computer elements contained within the housing.

Appl. No.:

7/364951

Inventors:

John J. Daly - San Carlos CA

Assignee:

GRID Systems Corporation - Fremont CA

International Classification:

G08C 2100

US Classification:

178 18

Abstract:

A hand held computer having a display screen which accepts writing from an electronic pen-type stylus has a cord which tethers the stylus to the computer. At the periphery of the computer is a flange or ledge forming a peripheral groove within which the cord resides when the stylus is stored in another wider part of the peripheral groove. The groove has a widened notch for receiving a larger-diameter portion of the stylus, such that the stylus snaps into a prescribed position lengthwise in the groove. In a preferred embodiment the cord is connected into the stylus via an internal spring in the stylus. The stylus thus gives some resiliency when pulled against the cord, and this feature is used to tightly seat the stylus in the groove or channel recess so that it is stored with the cord under some tension.

Assignee:

GRID Systems Corporation - Fremont CA

International Classification:

H01R 13428
H05K 710
H01H 920

US Classification:

439136

Abstract:

A hand held portable computer is secured to a peripheral computer component or expansion module in a snap-on arrangement which automatically effects engagement of bus connectors between the two components. The hand held computer has four openings in its back or under side. Two of the slot-like openings have fittings within them or are so shaped as to receive L-shaped or hook-shaped brackets of the peripheral component. The brackets may be inserted in the slot openings when the computer and the expansion module are held obliquely angled with respect to each other. The computer is then swung down until its back or under side engages against the top of the peripheral component, whereupon a pair of protruding hook members extending at the top surface of the peripheral component engage the computer and snap into locking engagement in the adjacent slot openings. The bus connection is made when the two components are brought together.

Inventors:

John J. Daly - San Carlos CA

Assignee:

Grid Systems Corporation - Fremont CA

International Classification:

H01M 310

US Classification:

429 99

Abstract:

A battery compartment for portable electrical equipment such as computers, tape recorders, VCR recorders, camera flash equipment and other such devices has an internal configuration and appropriate electrical connections to receive at least two different types of battery cells which may be of different dimensions. These can include standard dry cell batteries and rechargeable NiCad batteries, for example. The power pickup from the two types of cells is different, so that non-rechargeable dry cells can be isolated from charge when external power is attached to the portable device, while rechargeable cells are not isolated from the charge. The different dimensions are accommodated by orientation of the one type of cell-receiving spaces at right angles to the other type of cell-receiving spaces so that incorrect placement of the cell types is prevented.
