摘要:
An improved data collection system utilizing at least partially integrated data collection and gathering devices and related peripherals. The system includes an at least partially wearable data collection terminal, associated peripherals, and a communication system. The data collection system may utilize a wearable data collection terminal having a computer processor, associated memory, inputs, and outputs. Associated peripheral devices may include voice inputs and outputs, an optically readable information set reader, a keyboard and/or touch-panel, intelligent-body-conforming battery packs, mass storage devices, user position and next task location device, a display, a printer, and a data communication system for both local area and wide area communication.

A portable data collection terminal has an elongate housing with a hand grip conforming rear surface. A front surface features a numerical keyboard adjacent a lower end of the housing and an LCD screen adjacent the keyboard toward an upper end of the housing. The display screen is of elongate rectangular shape, its length extending longitudinally of the housing of the data terminal. The active area of the display screen is covered by a touch sensitive overlay screen which is configured in one mode of operation of the data terminal into an alphabetical keyboard. The orientation of the display is switchable between orientations in which the line direction of the displayed data extends across or longitudinally of the data terminal. The keys of the numerical keyboard are identified by indicia disposed on a template. The orientation of the template may be sensed to switch the orientation of the displayed data and touch sensitive key identifiers to correspond to the orientation of the indicia on the template. As a further embodiment an electromagnetic activation by a pen may be used to enter data into a data terminal. Power saving shutdown extends the battery life of the data terminal. A shutdown mode permits resumption of operations by depression of a key. During operations power consumption is reduced by efficient distribution of operations control between microprocessors. The microprocessors have shared access to and control of system operations.

A portable data collection terminal system has a housing having a display screen with coincident graphic data input and a keyboard on the frontal side thereof. An accessory pod, having a width less than the width of the display screen and a handgrip extension adapted to hold a selected accessory device, such as a laser scanner, is disposed on the housing, opposite said frontal side. The accessory pod has one or two activation, diaphragm-type switches disposed in a pod wall disposed transversely to the handgrip extension and extending outwardly from, opposite the frontal side, the housing. The switch 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.

摘要:
A portable, hand-held data collection terminal is of modular structure including, among other modules, multiple endcap modules and radio frequency communications pod modules, each of which may be chosen from a plurality of modules available for assembly into the terminal unit therby providing a plurality of modular combinations thereof. The functions of the multiple modular combinations are activated and controlled by a virtual trigger on a touch sensitive display. The virtual trigger may be positioned anywhere on the display to ergonomically accommodate different users. The terminal evaluates touch images retrieved from the touch sensitive display to determine whether they constitute an intentional touch. Unintentional touching will not activate the virtual button. Various other safety and power saving features are provided via orientation and motion sensors placed within the terminal.

A three dimensional digital spectrum modulation spread spectrum technique (DSM-X) that improves channel diversity by providing multiple bands within the available portion of the frequency spectrum increasing the number of available channels. The system also improves the channel immunity through the use of at least three dimensions of pseudo-random data encoding, which adds two levels of pseudo-random frequency allocation to the pseudo-random data encoding used in prior DSM systems. The three dimensions of pseudo-random allocation may include pseudo-random data encoding, pseudo-random frequency pattern allocation among a plurality of bands defined within the assigned frequency spectrum, and pseudo-random frequency sequencing among a plurality of channels defined within each band. Additional levels of pseudo-random encoding may be implemented in direct sequence coding for header data, repeat packet timing, and packet iteration timing.

Disclosed is an improved noise reducing apparatus using an anti-circuit, including a digital logic circuit and a digital anti-circuit corresponding to the digital logic circuit. The digital anti-circuit functions to cancel noise generated by the digital logic circuit. The anti-circuit includes logic to generate a similar number of switching edges as the logic circuit, where the anti-circuit edges are in the opposite direction as the logic circuit. The anti-circuit may have a circuit structure close to that of the noisy circuit, or can be formed of components different in structure but generating an output pattern similar to (and opposite from) the noisy circuit. In some embodiments, the differently structured components can include a state machine coupled to a memory or look-up-table.
