Abstract: A portable lightweight combination laptop and pad computer has a display (20) mounted on a main housing (10) for movement between a closed position and an open position. In the closed position, a keyboard (15) is covered by the undersurface of the display (20) and the display viewing surface (21) remains visible so that the computer may be used in the pad mode with a conductive stylus (30) for data and command entry. In the open position, the keyboard (15) 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 (20) is mounted to the housing (10) by a four bar hinge mechanism, and a pair of latches (50) 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.

Abstract: A computer memory card (10) which slides into place to a position of use in a computer (22) has an identifying label (14) adhered onto one side of the card. The label extends beyond the edge of the card (10) to provide a tab or tongue (16) for gripping by a user when the memory card is to be removed. In another embodiment the flexible tab is secured to the memory card independently of the label.

Abstract: A hand held computer (10) of a type used for such activities as taking inventory, recording signatures on delivery, keeping a route agenda, etc. has a large screen (12) and preferably is without a built in keyboard. The tablet type computer is thin in profile, light in weight and is easily carried and used. Programming in the computer enables an operator to select from various forms available for display on the screen (12), enables character recognition for items printed on the screen (12) using a conductive stylus (29), enables the recording in memory of signatures, graphics or any other material entered on the screen, and enables other convenient functions. Certain preferred features of the computer enable it easily to be converted into a full function desk top computer with a keyboard, expansion module and stand.
