Abstract: A protective case for housing a portable computer having a keyboard and a display, which protective case includes a keyboard case for receiving the keyboard and a display case for receiving the display. The display case is pivotally attached to the keyboard case and is movable between an open position and a closed position relative to the keyboard case. The axis of rotation of the display case relative to the keyboard case is coaxial with the axis of rotation of the display relative to the keyboard of the portable computer. An articulating handle is provided which attaches to both the keyboard case and the display case, and articulates about a pivot pin as the display case moves relative to the keyboard case. Additionally, the handle may be moved between an unlatched position whereby the display case pivots freely relative to the keyboard case, and a latched position whereby the display case is retained against movement relative to the keyboard case. In the unlatched position, the handle articulates about a pivot pin which is parallel to the axis of rotation of the portable computer. In the latched position, the pivot pin is substantially perpendicular to the axis of rotation of the portable computer thereby preventing movement of the display relative to the keyboard.

Abstract: A headphone assembly adapted for engaging a user's head includes an adjustable headband having first and second ends. A right ear piece is attached to a first end, and a left ear piece is attached to a second end of the headband. Each ear piece is substantially semi-circular shaped, and has a substantially inverted U-shaped shell having an inverted U-shaped inner wall. The U-shaped inner wall defines an acoustic cavity having a bottom end opening for receiving approximately the top half of the user's ear. A rear wall of the acoustic cavity has a number of holes extending therethrough behind which a speaker is mounted. An inverted U-shaped chamber is provided about the acoustic cavity. The right ear piece chamber will hold the electronic circuitry necessary for a cordless receiver. The left ear piece has a similar chamber which accepts a power board. A dome-shaped cover plate covers each of the speaker elements and the respective power board and circuit board, with the user's ear only partially enclosed by the ear piece. Alternatively, a planar cover plate covers each of the speaker elements and the respective circuit board, and a lower ear piece is pivotally attached to the upper ear piece for movement between an open position and a closed position. The lower ear piece also includes an acoustic cavity and has an open upper end for communicating with the bottom end opening of the U-shaped inner wall.

Abstract: A portable device (10) for data collection by an operator (11) includes a data entry unit (12) for entry of data other than by scanning and a module (14) having a display (50) for display of information and a scanner (51) or other auto-identification device for data collection. Data entry unit (12) operates both when carried by hand and while carried on operator (11) other than by hand. Module (14) is detachably carried by data entry unit (12) and operates both while module (14) is carried by data entry unit (12) and while detached therefrom. Data entry unit (12) includes a module carrier (70) for adjustably, detachably carrying display/scanner module (14). Because module (14) includes both a display and scanner, both are always within the line of sight of operator (11), greatly facilitating use of device (10). Because data entry unit (12) includes the remaining components, module (14) is lightweight and may be used for long periods without fatigue.
