Abstract
Abstract An electrical recording and display apparatus for performing the function of a chart recorder comprises a solid state display device (24) controlled from a memory (20) by a display controller (21). The memory (20) receives signals in the form of 8-bit binary numbers digitised by a signal digitiser (11) from an analogue input signal. The display device (24) graphically displays a set of the signals stored in the memory and this can be "scrolled" through all the information stored in the memory in a manner similar to a chart recorder.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
122 words
Electronic recording and display apparatus characterised in that it comprises means (11) for digitising the value of incoming electrical input signals varying in value with time, said digitising means (11) including converter means (25,26) for converting the input signal to pulse form, and integrator means (27) for integrating the pulses to produce a digital signal representative of the analogue value of the input signal, a random access memory (20) for storing successively generated digital signals representing the mean value of the input signal over the sampling interval at successively addressable storage locations in a predetermined reading pattern in the memory (20), and a solid state matrix display device (24) operable to display a plurality of successive digitised values of the input signal.
Claim 2
Dependent Claim
122 words
Electronic recording and display apparatus characterised in that it comprises means (11) for digitising the value of incoming electrical input signals varying in value with time, said digitising means (11) including converter means (25,26) for converting the input signal to pulse form, and integrator means (27) for integrating the pulses to produce a digital signal representative of the analogue value of the input signal, a random access memory (20) for storing successively generated digital signals representing the mean value of the input signal over the sampling interval at successively addressable storage locations in a predetermined reading pattern in the memory (20), and a solid state matrix display device (24) operable to display a plurality of successive digitised values of the input signal.
Claim 3
Dependent Claim
44 words
Electronic recording and display apparatus according to Claim 1, characterised in that the display device (20) is operable to display the individual-digitised signals in such a manner that the magnitude of the digitised signal is represented as a linear dimension on the display (20).
Claim 4
Dependent Claim
38 words
Electronic recording and display apparatus according to Claim 1 or Claim 2, characterised in that there are means (18,21) for selecting a set of displayed digitised values from the total set of stored values in the memory (20).
Claim 5
Dependent Claim
72 words
Electronic recording and display apparatus, according to any of Claims 1 to 3, characterised in that the solid state display device (2 4 ) displays such digitised signal as a line on the screen, adjacent digitised signals in a set thereof displayed on the screen being displayed as adjacent lines and the length of each line from a given edge of the display screen(24) representing the magnitude of digitised signal represented thereby.
Claim 6
Dependent Claim
39 words
Electronic recording and display apparatus according to any preceding Claim, characterised in that there are further provided permanent storage means (31) and means (21,22) for transferring the information from the memory (20) to the said permanent storage means (31).
Claim 7
Dependent Claim
34 words
Electronic recording and display apparatus according to Claim 5, characterised in that the permanent storage means (31) comprise a magnetic recording medium such as tape, disc or drum, or a programmable read-only memory device.
Claim 8
Dependent Claim
30 words
Electronic recording and display apparatus according to any preceding Claim, characterised in that the solid state display device (24) is a liquid crystal matrix display, or an electro luminescent display.
Claim 9
Dependent Claim
80 words
Electronic recording and display apparatus according to any preceding Claim, characterised in that there are provided display control means (21) for controlling display of a selected plurality of digitised signals from the memory, the control means (21) being operative to change the set of displayed signals by one to the signal stored in the adjacent address location in the memory (20) after each set has been displayed for a predetermined time whereby to effect apparent "scrolling" through the stored information.
Claim 10
Dependent Claim
52 words
Electronic recording and display apparatus according to Claim 8, characterised in that the display control means (21) is operative to display two or more sets of digitised signals selected from the signals stored at different address locations in the memory (20) whereby to effect a comparison display on the display device (24).
Claim 11
Dependent Claim
73 words
Electronic recording and display apparatus according to any preceding Claim, characterised in that the display controller (21) is further selectively operable to cause the display device (24) to display data representing the numerical values of the digitised input signals and/or the value of other signals derived therefrom in addition to or in place of the graphic display of the digitised signal variation, this- data display being in the form of alpha numeric characters.
Claim 12
Dependent Claim
60 words
Electronic recording and display apparatus according to any of Claims 6 to 10, characterised in that the permanent storage means (31) comprises a solid state memory device provided with releasable electrical terminals whereby the memory device (31) can be removed and replaced periodically so as to provide a separate permanent record of the data over a given recording time period.
