A device ( ) for user replacement of an inoperable, first boot loader program includes a boot memory ( ) including the first boot loader program beginning at a first address, a PCMCIA card ( ) including a second boot loader program beginning at a second memory address, and a selector switch ( ). Selector switch ( ) receives the user selection of one of the first boot loader program and the second boot loader program, and generates a selection signal corresponding to the user selected boot loader program. Combinational logic ( ) receiving the selection signal, enables the selected boot loader program and disabling the other boot loader program.

Device and method for noninvasive, user replacement of an inoperable boot program

A self-configurable, adaptable and programmable (hereinafter &ldquo;CAP&rdquo;) I/O bus ( ) is provided in a digital computer ( ) to establish compatibility between the input/output bus of computer ( ) and an incompatible input/output bus of an external module ( ). Computer ( ) includes a field programmable gate array (FPGA) ( ) for translating the bus configuration used by module ( ) to that employed by computer ( ). Two preselected CAP I/O Bus conductors ( ) pass an identification number from the module ( ) to computer ( ) that points to the location of the information necessary to compatibly configure FPGA ( ). This information, which includes a bus logic FPGA image file and a device driver, and may include a protocol driver, may be found in one of several locations, including onboard computer ( ) in memory, onboard module ( ), or at an external site such as a server ( ) accessible via the Internet. Computer ( ) retrieves the configuration information from the location corresponding to the identification number, configures FPGA ( ) and establishes communication between the two input/output buses.

Field-configurable, adaptable and programmable input/output bus interface and method

A hand-held portable computer is disclosed. The computer includes a housing at least partially enclosing computer electronics, a visible display screen supported by the computer housing and a handle assembly connected to the computer housing. The handle assembly includes a handle support, a support retainer affixed to the housing at a location opposite the screen and a handle supported by the handle support. The support retainer adjustably connects the handle support to the computer housing. In the preferred embodiment, the handle support is rotatably adjustable with respect to the computer housing. The handle support includes an annular ring having a plurality of indentations on one surface and the support retainer includes a detent which engages a selected one of the indentations to secure the handle support in a desired rotational orientation.

Interactive display user interface computer and method

A portable electronic work slate unit includes a customizable array of data devices and input/output devices which are selectively integrated in a compact and highly ergonomic structure. Increased operator productivity is accomplished by use of several possible user interface media including a multi-function display and input/output unit including a digitizer, position sensitive screen, and video display panel. Selectively integratable user interface components include a bar code scanner, RF modulator for radio frequency communication, modem, audio input/output, as well as the multi-purpose display. All components are integrated by use of a handle unit which can house a battery as well as removable modules in a manner so as to minimize operator fatigue and discomfort, as well as enhance productivity.

All components are integrated by use of a handle unit or module docking assembly which can house a battery as well as removable modules in a manner so as to minimize operator fatigue and discomfort, as well as enhance productivity. Configuration, reconfiguration and updating of work slate units by choice and selection of removable modules, from a variety of different types of modules, is enhanced by utilization of standardized interfaces which are intercoupled to a common signal bus. The bus configuration in combination with a bus controller functions as an intelligent bus capable of identifying types of removable modules and configuring communication protocols for operation with different types of removable modules.

Impacts to the case of a portable electronic unit including a display are dissipated by a plurality of thermoplastic elastomeric damping elements which isolate an internal frame unit, carrying the display and associated electronic components, from contact with the enclosure. Each damping element is provided with corresponding positioning structures within the case to ensure that the frame unit 'floats' on protective shock absorbing material to provide three-dimensional support and damping of impacts incident from any direction. Damping elements may take the form of small caps of elastomeric material at spaced positions around the periphery of the frame unit. Electronic connections to the display screen are accomplished using flexible connectors to maintain the mechanical isolation of the display screen from the rest of the unit.
