Title: LCD touch screen with reflective backlight location detection.
Inventor: KIM CHEOL-SE
IPC: G06F3/042
Filed: 2009-12-18
Abstract: Disclosed is a photo-sensing touch panel liquid crystal display. The display includes a liquid crystal panel 100 including a touch sensor provided in each of the display's pixels. The display also has a readout integrated circuit (ROIC) 210 which receives a readout voltage value from readout lines in the touch panel, and an ADC convertor 220 which converts the analogue voltage transmitted to the ROIC into a digital value. A processor 230 calculates a value by subtracting a corresponding value detected from the ADC convertor when no-backlight is applied from a value detected from the ADC convertor when a backlight is applied. The position of a touch point on the photo-sensing type touch panel is then detected, if the value from the processor is beyond a threshold value. Also disclosed is a LCD display with a backlight and pairs of sensors to detect the amount of light when the backlight is on and when the backlight is off.

Title: Electronic controller for process control systems
IPC: G05B11/42
Filed: 1968-03-04
Abstract: 1,224,011. Automatic control. FISCHER & PORTER CO. March 4, 1968 [March 3, 1967], No.10466/68. Heading G3R. In an electronic controller for a process in which signals corresponding to the magnitude of a process variable and its set point are supplied to a differential amplifier controlling the process, the amplifier output is chopped and fed back to the amplifier input through a transformer and rectifier. In Fig.1 an electrical signal corresponding to rate of flow is applied at terminal 11 and a local or remote set point signal selected by a switch 17. The two signals are applied through a reversing switch 19 to a differential amplifier 10 the output of which corrects, through transistor stages 23, 24, the setting of a flow-controlling valve 28. An amplifier 20 associated with a condenser 21 . develops a differential component of control and feedback from transistor 23 through a condenser 37 develops an integral component of control. The signal applied to the feedback circuit is chopped by a transistor switch 34 operated by a multi-vibrator 35 so that it can be passed through an isolator transformer 33 and re-converted to a direct voltage by a rectifier 36. Operation of a changeover switch 25 transfers the output of transistor 24 to a dummy load 26 so that valve 28 can be controlled manually through transistors 31, 32 from a remotely controlled motor-driven potentiometer 29. Under these conditions the output of transistor 31 is applied through a chopper 40, isolator transformer 39 and rectifier 40 to condenser 37 to ensure that the charge on the latter is such that transfer to automatic control will be bumpless. The Specification also describes arrangements of meters, including meter 15, to measure various input signals and to facilitate bumpless changeover between the local and remote set points.

Title: Improvements relating to fugitive colouring of textile materials
Inventor: MEITNER WALTER
IPC: D06P5/13
Filed: 1953-04-21
Abstract: Textiles of unmercerized cotton, viscose rayon, wool, cellulose ester fibres or synthetic polymer fibres such as nylon, or mixtures thereof, are fugitively coloured by applying an aqueous dispersion of a pigment prepared from a direct cotton dye and a protein such as casein, the pigment being insoluble in water but soluble in alkaline liquors so as to be readily removable by mild scouring.  The pigment dispersion may be prepared by acidifying an aqueous solution containing a direct cotton dye and a protein to a pH of about 3.5 or by adding to the solution a small amount of a compound of a multivalent metal such as aluminium, e.g. sodium aluminate, and acidifying to a pH of 5-6.  Alternatively, a dispersion of pH 7 may be obtained by adding a salt of a multivalent metal such as calcium, e.g. calcium chloride, to a neutral aqueous solution of the dye and protein.  As a further alternative, an aqueous solution of the dye and protein may be acidified to pH 4-5 to precipitate an insoluble pigment, the precipitate being washed, dried, ground and then dispersed in water to yield the pigment dispersion.  Acidification may be effected by the addition of a weak volatile organic acid such as acetic acid or a mixture of acetic acid and sodium acetate.ALSO:Aqueous water-insoluble-pigment dispersions for use in the fugitive colouring of textiles (see Group IV(c)) contain a pigment prepared from a direct cotton dyestuff and a protein such as casein.
