Abstract

A portable computer apparatus having a dual-pivot articulating display screen capable of being adjusted to a plurality of different viewing angles as desired. In the preferred embodiment, the disclosed apparatus is an implantable medical device programming unit. The substantially flat display screen is movable from a closed position in which it is substantially parallel with an upper surface of the apparatus, to any of a plurality of open positions wherein the display can be viewed by an operator. The display screen is coupled to the main housing of the apparatus by means of a pivoting link arm, and the central portion of the bottom edge of the display screen is provided with a support member extending therefrom, which may be located in one of a number of defined locations within a support channel in the upper surface of the main housing of the apparatus. The display is preferably touch sensitive, so that user interaction with the apparatus is accomplished by a stylus or the like. The disclosed apparatus is provided with an internal ECG strip-chart printer. A compartment in the apparatus is provided for storage of a magnetic programming head, the touch-sensitive screen stylus, and patient ECG cables. A separate compartment is provided for storage of an AC power cord.

Claims

1. A portable computer apparatus, comprising:

a main housing having an upper surface and containing computer circuitry;

a display screen having side edges and upper and lower edges;

a link arm coupled between said main housing and said display screen, said link arm pivotally coupled at one end thereof to said main housing and pivotally coupled at a second end thereof to said display screen, at a location spaced from said lower edge to enable said screen assembly to articulate relative to said housing;

an engagement mechanism disposed between said display screen and said housing cooperating to stably maintain said screen at any of a plurality of viewing angles, said housing provided with a support channel located centrally on said upper surface of said housing, said engagement mechanism comprising a support member extending from a central location on said lower edge of said display screen, engageable with said support channel.

2. An apparatus in accordance with claim 1, wherein said link arm is coupled to said display screen along a side edge thereof.

3. An apparatus in accordance with claim 1, wherein said support channel defines a plurality of detents therein for engaging said support member.

4. An apparatus in accordance with claim 1, wherein said engagement mechanism comprises a support member adapted to be frictionally engaged in said support channel.

5. A portable computer apparatus, comprising:

a main housing, having an upper surface, said main housing containing

computer circuitry;

a display screen having a substantially flat display surface and having top, bottom, left and right edges;

left and right link arms coupled between said main housing and said display screen, said left link arm pivotally coupled at one end thereof to said main housing upper surface and pivotally coupled at a second end thereof to said left side of said display screen, said right link arm pivotally coupled at one end thereof to said main housing upper surface and at a second end thereof to said right side of said display screen;

a support member, extending from a central portion of said bottom edge of said display screen;

a support channel disposed on a central portion of said main housing upper surface, extending from a forward location to a rear location thereon, said support channel adapted to engage said support member at a plurality of locations therein;

said display screen movable from a closed position wherein said display surface faces and is substantially parallel to said main housing upper surface, to any of a plurality of different viewing angles, said support member being engaged at a different location in said support channel for each of said different viewing angles.

6. The apparatus of claim 5, further comprising:

left and right latch mechanisms, disposed on said main housing upper surface and adapted to secure said display screen in said closed position.

7. The apparatus of claim 5, further comprising:

a carrying handle, disposed on a forward end of said apparatus;

a storage compartment having a hinged cover which defines a portion of said upper surface;

a power cable compartment having a hinged cover, disposed on a rear end of said apparatus.

8. The apparatus of claim 5, wherein at least one of said link arms is hollow, and wherein a wire for conducting an electrical signal from said computer circuitry to said display screen passes through said at least one hollow link arm.
