`
`BACKGROUND OF THE INVENTION
`
`The invention relates generally to data collection and
`processing systems and more particularly to portable data
`terminals as operator manipulatable data input and output
`devices with display and veri?cation of data.
`The invention herein is a further improvement of related
`subject matter contained in the cross-referenced prior patent
`applications. which prior patent applications are relied upon
`for priority rights in previously described novel features.
`Portable data terminals are generally known components
`of state of the art business systems. The data terminals may
`be taken to merchandise storage facilities for inventory
`control or customer service transactions. or may be used in
`any one of various other commercial applications to serve as
`data input or output devices for central data processing and
`control stations.
`Central data processing or control stations are most useful
`when business data are always current and readily available.
`Prompt data entry and retrieval at the working level through
`various operator controlled portable data terminals is rec
`ognized as a basis for optimizing. among various business
`activities. inventory control and customer service activities.
`business forecasting and marketing operations. to name just
`a few.
`Increased versatility in data input and output arrange
`ments tends to increase power usage of the portable data
`terminals. thereby decreasing usage periods between battery
`exchanges or recharging operations. Touch sensitive or pen
`actuated data input systems are known. However. in the past,
`such pen actuated data input systems were generally limited
`to the use of pens for digitizer boards or in conjunction with
`full keyboard type computer terminals. While the former
`devices are considered limited in their application. the latter
`are comparatively bulky. even as lap top computers. and are
`not useful for practical data entry and retrieval in shop,
`warehouse. store or delivery route environments.

`
`SUMMARY OF THE INVENTION
`
`45
`
`The objective of the present invention was early on to
`expand on the utility of relatively small. portable. hand-held
`data collection terminals. The invention recognizes a need
`for greater versatility in hand-held data terminals. thereby
`improving indirectly an overall usefulness of a business
`system which uses a number of these data terminals as
`roaming data input and retrieval devices.
`It is therefore an object of the invention to provide an
`improved compact data input and display device with
`increased functionality.
`It is another object of the invention to arrange an alpha
`numeric keyboard for multi-orientational use.
`Further in accordance herewith. it is an object of the
`invention to provide a pen-activated data input device which
`interactively may be prompted through display screen
`prompts.
`Another object of the invention is to provide a robust data
`terminal having a display screen sized to permit operator
`input via pen strokes and having the capability to change to
`keyboard enu'ies interchangeably with entry via pen-type
`signals.
`

`Yet another object of the invention is a power manage
`ment control function implemented through software con
`trolled microprocessor functions. the power management
`function including selectively shutting the data terminal
`down without loss of current data interchange status states
`on an Input-Output bus (IIO Bus).
`According to one aspect of the invention. it is conse
`quently contemplated to increase the data input capacity of
`a portable data terminal with a touch sensitive liquid crystal
`display overlay. The touch sensitive display overlay may
`function as a keyboard or as a provision for entering graphic
`data such as signatures. Another keyboard may be a numeri
`cal keyboard or may be activated as a function keyboard to
`supplement a touch sensitive keyboard implemented as an
`overlay of a display screen.
`Another object of the invention is to provide an accessory
`pod having a wall with one or more diaphragm-type acti
`vation switches arranged to be operable by a user’s thumb or
`?nger in order to activate an accessory. such as a scanner.
`attached to the accessory pod.
`In a particular embodiment in accordance with the
`invention, keys of the touch sensitive keyboard of the
`display screen of the portable data terminal may be selec
`tively reorientable with respect to the data terminal. In
`accordance with a particular feature of the invention. the
`keys or key areas of the touch sensitive keyboard are
`reoriented by switching key assignment areas within the
`touch sensitive display screen and by reorienting indicia
`within each of the switched touch sensitive areas of the
`board to change the orientation of the indicia to correspond
`to a change orientation of the keyboard of the touch sensitive
`area.
`Further in accordance with the invention. a keyboard is
`disposed adjacent a display screen of a portable data termi
`nal in a frontal face of the data terminal. The keyboard
`includes an array of keys, each key having an assigned
`function, and an array of indicia identifying the function of
`each of the keys of the array. The array of indicia is disposed
`on a matrix removably attachable to the frontal face of the
`data terminal. The array of indicia may be removed and
`replaced by another array of indicia. showing reassigned
`functions of each of the keys. and the functions of the
`respective keys are reassigned in accordance with such other
`array of indicia. Alternatively. molded keys may include
`permanent indicia which display functions inherent to
`default settings of a data terminal.
`Also according to the present invention. a data terminal
`has a display screen and graphic data input surface coinci
`dent with and disposed beneath the display screen. Data
`input into the graphic data input surface may be obtained
`either via an electromagnetic pen. also referred to as an
`active pen. or via a touch sensitive screen via a pointed
`object. such as a stylus.
`Further in accordance herewith. the data terminal includes
`operation shadowing circuits which include a function of
`shadowing Input-Output (I/O) device states and a function
`of storing microprocessor register states during a shutdown
`procedure. Pursuant to the shadowing and microprocessor
`register storage. the data terminal may be shut down and
`m-activated without loss of control or 1/0 status data and
`with the ability to complete an operation in progress during
`the time of shutdown of the data terminal.
`Further in accordance herewith. a data terminal includes
`a shock and weather resistant housing and a keyboard
`orientation with respect to a display screen which causes an
`included angle to protect both the keyboard and the display
`

`screen from contact with a flat hard bottom surface during a
`fall of the data terminal against such surface. Co-molding of
`shock absorbing material to the surface of the housing
`distributes impact forces to which the data terminal may be
`exposed as a result of a fall. In a preferred embodiment,
`resilient sealing strips interposed between access covers and
`the housing provide a weather—sealed housing.
`A housing of the data terminal includes top and bottom or
`base housing shells. The base housing shell is an accessory
`base and has a central accessory attachment opening. The
`accessory attachment opening or accessory pod opening
`may by covered by a removable base cover when no
`accessory pods are attached. A base cover in accordance
`herewith is in a shape of a multi—function handgrip or
`terminal grip and stabilizer. The handgrip comprises a
`longitudinally centered concave. transversely peaked stabi-
`lizer shape with dual. laterally offset. symmetrical handgrip
`ridges with palrnrest indentations for alternatively left and
`right hand gripping functions. The dual handgn'p ridges
`include co—molded ribbing which also provides impact resis—
`tance. The removable base cover may be exchanged for an
`accessory pod which is centrally disposed. symmetrically
`with respect to a longitudinal central axis of the housing of
`the data terminal. The accessory pod has a width transverse
`to the longitudinal axis which is less than the transverse
`width of the data terminal, the accessory pod including a
`handglip portion by which an operator may hold the data
`terminal while operating the data terminal.
`A handstrap may be attached to upper and lower ends of
`the base housing shell. The handstrap has a split loop
`attachment to the lower housing shell. The split loop attach-
`ment straddles a docking latch eye disposed on the base
`housing shell. The docking latch eye engages a latch hook on
`a dock when the data terminal is inserted into a docking
`device. Co—molded material disposed on the top housing
`shell of the data terminal cooperates with the latch eye to
`retain resilient pressure on the latch hook for retaining
`surface contacts on the data terminal in contact with mating
`spring contacts of the docking device while the data terminal
`remains inserted into the docking device.
`Contacts in each of transverse rows of surface contacts
`disposed at a lower end of the base housing shell are
`transversely groupwise staggered and longitudinally overlap
`with the contacts of the other. adjacent group to provide a
`wider contact surface for engaging spring contacts of a
`docking device. when the respective data terminal is inserted
`into a docking receptacle of the docking device. The inven-
`tion contemplates a single-receptacle docking device and a
`multi—cavity or multi-receptacle docking device. The data
`terminal as well as the docking devices feature Ethernet as
`well as RS-232 or compatible or equivalent LAN (Local
`Area Network) communications provisions.
`The base cover of the data terminal is exchangeable for
`any of a number of other bases or base pods, each base
`having a particular one of a number of desirable accessory
`features. At least one of the base pods is contemplated to
`include a scanner for reading indicia which may be disposed
`on a surface external and separate from the data terminal.
`The scanner may. for example. be a bar code scanner. An
`operator may insert fingers or a portion of the hand between
`the housing and one of the handstrap provisions to retain the
`unit by friction between the hand and the strap.
`In addition. the accessory pod has one or two activation.
`diaphragrn—type switches disposed in a pod wall disposed
`transversely to the handgn'p extension and extending out—
`wardly from. opposite afrontal side. the housing. The switch
`
`6
`or switches are connected in parallel. if more than one. and
`are disposed near an end of the pod wall such that they are
`operable by either a user’s thumb or finger.
`Various other features and advantages of the invention
`will become apparent when the detailed description below is
`read in reference to the appended drawing.
