Patent number: 5590405Abstract: A communication method wherein rate of information transfer with a given signal transmitted or received at a transceiver node is dynamically varied as a function of the relative quality of the transmission environment. The method employs a responsive buffering process at each communication node that permits this rate to be varied somewhat independently of the rate at which information is transferred to or from the transceiver node. In a particular application, the invention permits information to be exchanged between a wireless signal having a variable error correction bandwidth and a fixed bandwidth data stream.Type: GrantFiled: October 29, 1993Date of Patent: December 31, 1996Assignee: Lucent Technologies Inc.Inventors: John J.

Patent number: 5015546Abstract: 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.Type: GrantFiled: June 12, 1989Date of Patent: May 14, 1991Assignee: Grid Systems CorporationInventors: Ken L. Dulaney, John J. Daly

Patent number: 4979636Abstract: This invention relates to a housing assembly design which reduces the number of screws required to attach the housing parts together. According to the preferred embodiment of this invention, the housing of a hand-held computer is assembled and held together by a combination of hooks, screws, and tabs. Preferably, the tabs mate with slots or grooves formed on the perimeter of apertures such as input/output ports in the housing. Once the housing is assembled, each tab forms part of the perimeter of the aperture into which it is inserted. The hooks and screws mate with corresponding hooks and screw holes, respectively, formed in the housing.Type: GrantFiled: June 12, 1989Date of Patent: December 25, 1990Assignee: Grid Systems CorporationInventor: John J.

Patent number: 4969830Abstract: 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.Type: GrantFiled: June 12, 1989Date of Patent: November 13, 1990Assignee: GRID Systems CorporationInventors: John J.

Patent number: 4927986Abstract: 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.Type: GrantFiled: June 12, 1989Date of Patent: May 22, 1990Assignee: GRID Systems CorporationInventor: John J.
