Abstract

Abstract To allow a salesman to record data relating to merchandise items which are to be ordered, a logging device comprises a casing in which are housed a keyboard, a display and associated circuits. The salesman locates a sheet containing a list of merchandise items, on the casing between two columns of light-emitting diodes. At the start of entry of an order, the top left-hand LED is illuminated under the control of a central processor unit, which simultaneously addresses a main memory storage location corresponding to the item alongside that LED. Data, such as quantity required, can then be keyed into that storage location, which already contains an identification code for that item. The salesman then operates a key which causes the CPU to scan through the LEDs, and the storage locations, in turn, until the next required item on the sheet is reached. Data relating to that item is then keyed-in. At the end of each day, the salesman couples a transducer to a public telephone and transmits the data to a computer at his base. Due to the automatic correspondence, at any instant, between the item indicated by an LED and the respective storage location containing the item identity code, the items can be listed in plain language and the salesman does not have to look up item codes. The order can, therefore, be entered rapidly and transmitted back to base without danger of incorrect codes being used.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 172 words
A portable data logging device, comprising data storage means; means to display a list from which items are to be selected and which can be replaced by another list external to the device from a portfolio of lists of given format without reference to any program of said device; means coupled to said storage means and operable to select and indicate item positions of said displayed list and to address a storage location of said storage means, allocated to said selected item position, which location stores an identifying code for said item position; and a keyboard coupled to said storage means and operable by an operator to enter into said storage means data relating to said indicated item position; wherein said means to select and indicate item positions is operable under the control of said operator to select said item positions sequentially or randomly without reprogramming said device; and wherein there is provided means operable by said operator to enter into said storage means an identity code for the particular list displayed.
Claim 2
Dependent Claim 172 words
A portable data logging device, comprising data storage means; means to display a list from which items are to be selected and which can be replaced by another list external to the device from a portfolio of lists of given format without reference to any program of said device; means coupled to said storage means and operable to select and indicate item positions of said displayed list and to address a storage location of said storage means, allocated to said selected item position, which location stores an identifying code for said item position; and a keyboard coupled to said storage means and operable by an operator to enter into said storage means data relating to said indicated item position; wherein said means to select and indicate item positions is operable under the control of said operator to select said item positions sequentially or randomly without reprogramming said device; and wherein there is provided means operable by said operator to enter into said storage means an identity code for the particular list displayed.
Claim 3
Dependent Claim 39 words
A device as claimed in claim 1, wherein the means to select and indicate item positions is also operable to move to the next listed item in response to actuation of a key on the keyboard by the operator.
Claim 4
Dependent Claim 24 words
A device as claimed in claim 1, wherein the storage means is operable to accumulate totals of data fed thereto relating to respective items.
Claim 5
Dependent Claim 27 words
A device as claimed in claim 1, including an alphanumeric display on which data to be fed to the storage means and/or contained therein can be displayed.
Claim 6
Dependent Claim 44 words
A device as claimed in claim 1, wherein power is supplied by a main battery; wherein the data storage means is at least partly volatile; and wherein a back-up battery is provided for supplying power to the volatile part of the data storage means.
Claim 7
Dependent Claim 22 words
A device as claimed in claim 1, including an interface for feeding data from the data storage means to a peripheral device.
Claim 8
Dependent Claim 34 words
A device as claimed in claim 1, including a transducer for coupling to a telephone for transmission of stored data from the data storage means to a remote receiver over a telephone transmission line.
Claim 9
Dependent Claim 49 words
A device as claimed in claim 1, wherein said means to display a list comprising a sheet on which said list is displayed, said sheet, in use, being located on a prescribed area of said device for cooperation with indicators of said means to select and indicate item positions.
Claim 10
Dependent Claim 33 words
A device as claimed in claim 8, wherein said indicators comprise a plurality of light-emitting diodes, a respective one for each item position of the displayed list, for indicating the selected item positions.
Claim 11
Dependent Claim 46 words
A device as claimed in claim 1, wherein in response to an operator instruction said means to select and indicate item positions is operable, after data relating to a plurality of items have been entered into said storage means, to cause said data to be displayed.
Claim 12
Dependent Claim 39 words
A device as claimed in claim 1, further comprising means selectively operable to cause said means to select and indicate item positions to move directly from one item position to any other item position as commanded by said operator.
Claim 13
Dependent Claim 38 words
A device as claimed in claim 1, further comprising means to store at least two programs for controlling operation of the device; and switching means operable by said operator to switch from one to another of the programs.
