Patent number: 5313053Abstract: A portable, hand-held data terminal of modular structure includes a base module with a keyboard and a display screen. A data collection and communications module includes a stacked arrangement of a communications interface main circuit board, a radio and a laser scanner assembly which are housed in a housing shell which is attachable to the base module. The radio is mounted in spaced relationship to one side of the main circuit board, while the laser scanner assembly is mounted to the other side of the main circuit board. A support frame and a plurality of ground planes in the sandwiched main circuit board and a routing circuit board form an RF cage for shielding RF interference which may be generated by the radio.Type: GrantFiled: December 8, 1992Date of Patent: May 17, 1994Assignee: Norand CorporationInventors: Steven E.

Patent number: 5023824Abstract: A hand-held portable data entry terminal is encased by an elongate housing of substantially rectangular dimensions. The housing includes upper and lower housing shells which are assembled into a water tight housing. The upper housing shell supports on an upper surface a display and a keyboard with typically alphanumberic keys. The area taken up by the display and keyboard defines an overall width of the data terminal which may exceed the width of a readily hand fitting grip. The terminal consequently includes in a central portion of its lower housing shell a grip conforming portion of an inwardly displaced lower wall bounded by inwardly converging angled sidewalls. The depression in the center portion of the housing adjacent opposite end portions is spanned by a resilient strap disposed longitudinally across the grip conforming portion. A user may insert a hand into a space defined between the strap and the inwardly displaced surface.Type: GrantFiled: February 9, 1990Date of Patent: June 11, 1991Assignee: Norand CorporationInventors: George E.
