Abstract: A holster assembly for a hand-held computer or other hand-held electronic device. The holster assembly has first and second holster sides connected together to define a receiving area with an open end and a substantially closed end opposite the open end. The open end is sized to allow the hand-held computer to be moved into and out of the receiving area between installed and removed positions. The first holster side is a molded, compressed foam structure having a first contoured surface shaped to substantially cover the first side portion when the hand-held computer is in the installed position. The second holster side is a molded, compressed foam structure having a second contoured surface facing the first contoured surface and being shaped to substantially cover the portion of the second side surface. A holster retaining strap is attached to the first holster side to allow the holster assembly to be retained on, as an example, the belt of a user or the like.

Abstract: A hand-held computer having a contoured housing with a head, a body, and a neck portion therebetween, the housing having a contoured protrusion positioned on the body portion substantially adjacent the hand-held computer's center of gravity. The contoured protrusion is sized and ergonomically shaped to correspond to a support portion of the person's hand between approximately the metacarpal-phalangeal joint ridge and the proximal phalangeal joints when the hand-held computer is carried by the person. The hand-held computer has a longitudinal axis and a display screen that is oriented at a positive angle relative to the longitudinal axis for improved viewing by the user of the display screen. The hand-held computer includes a scanning unit that scans along a scanning axis that is angled downwardly at a negative angle relative to the longitudinal axis. A plurality of computer keys define a keypad plane such that the tilted display screen is at a selected angle relative to the keypad plane.
