Abstract
Systems and methodologies are disclosed for isolating a portable hand held electronic unit from external mechanical shocks and/or vibrations by dampening them at several levels. The system can absorb an external mechanical shock at three different levels by employing an external bumper system, elastic housing design features, and an internal frame isolation. Moreover, such isolation assembly simplifies production of the portable electronic unit by enabling a “build to order process” according to a customer's specification.
Claims20
A portable data terminal, comprising:
- a housing of a bar code reader comprising a segment being rotatable about a junction of the housing;
- and
- at least one circuit board partially encased by a rigid body within the housing, the rigid body positioned on a bumper system surrounding a perimeter of the rigid body inside the housing such that the rigid body is allowed to shift laterally within the housing, the bumper system interposed between the rigid body and the housing.
A portable data terminal comprising:
- a plurality of circuit boards mounted on a sub frame, being at least partially encased by a rigid body positioned on a bumper system surrounding a perimeter of the rigid body within the terminal housing such that the rigid body is allowed to float within the housing;
- and
- a resilient member of the bumper system interposed between the rigid body and the housing.
A method for manufacturing a plurality of bar code reading mobile terminal types, comprising:
- providing common components for the mobile terminal types that are respectively generic to the types;
- assembling a particular mobile terminal type by at least a subset of the respective common components;
- receiving a customer order for a specific mobile terminal type requiring at least one unique component, and fabricating the specific type via employment of the common components and the at least one unique component on a rigid body;
- providing a flexible housing for the mobile terminal comprising a handle coupled to a surface of the terminal housing via a hinge;
- and
- positioning the rigid body on a bumper system inside the terminal housing, wherein the unique component is not mounted in a fixed position within the housing and the bumper system surrounds a perimeter of the rigid body.
