Abstract: 1289753 Switching systems for consumer devices S A O RYDBORN 17 Feb 1970 [18 Feb 1969] 7450/70 Heading H2H [Also in Division G1] A circuit for connecting and disconnecting a load such as an incandescent lamp L from a supply applied to terminals A, B, comprises a switch circuit including a unijunction transistor T3, a blocking circuit including a transistor T1 and adapted to prevent operation of the switching circuit at a predetermined ambient light intensity and a timing circuit adapted to disconnect the load from the supply after a predetermined time. On depression of push button switch S having an associated glow lamp G, a thyristor D5 becomes conductive and enables a capacitor C3 of the timing circuit to discharge through a resistance R7. The capacitor then begins to charge via a resistor R13 for the predetermined time but during the charging period the transistor T1 and a transistor T2 are non conductive so that the transistor T3 oscillates. A triac D1 therefore conducts so that the lamp is connected to the source. When the charge on the capacitor C3 reaches a certain level, the transistors T1, T2 become conductive so that the transistor T3 stops oscillating and therfore the triac D1 is switched off, thus disconnecting the lamp from the source. When the predetermined ambient light intensity exists, a light sensitive resistor R12 maintains the transistors T1, T2 conductive thereby preventing the lighting of the lamp. In a modification an increased number of transistors including a programmed unijunction transistor is used.

Abstract: 1333074 Digital-digital converter SUMLOCK ANITA ELECTRONICS Ltd 8 July 1971 [15 July 1970] 34240/70 Heading G4H A digital-digital converter is adapted to convert an input from a key-board switch into a pulse train indicative of the switch and comprises a diode matrix to provide a signal on four parallel leads indicative of the activated switch, which signal is supplied to four comparators connected to corresponding outputs of a recycling counter such that a "re-set" pulse is delivered to a two-state device at the start of each counting cycle and a "set" pulse is applied upon simultaneous equality in all four comparators, the duration between the two pulses being significant, and during which pulses are applied to an output of the converter to form the pulse train. In the Figure, a first recycling counter 10 comprising M.O.S. transistors 16-19 and NOR gates 21-25 is supplied with clock and inverted clock pulses at # 1  # 2  respectively, outputs A-D and their inverses #A-#D being taken to an array of gates 31-45 as shown to produce output pulses 1-8 in cyclic sequence. Pulse "8" is taken as origin of the cycle and used as clock input to a second recyling counter 46 having outputs connected to the 4 comparators 51-54 as shown. Further outputs B, C, D of counter 46 are taken to NOR gate 74 to define the start of the cycle of 46 and to apply a reset signal to a cross-connected pair 70, 72 of NOR gates, the arrangement being a logical "1" appears the output of one of the NOR gates 80, 86 at the occurrence of the leading edge of the reset signal. Whilst this is present, pulses either on output "2" or "3" of counter 10 gate transistors 82, 88 respectively to apply logical "1" pulse to output 94. Upon simultaneous equality of comparators 51-54, NOR gate 66 is enabled by a pulse on output "1" of counter 10 and the leading edge of this pulse removes the "1" from the output at 80, 88. This occurs for every cycle of counter 46 whilst a switch is depressed. The two transistors 82, 88 and gates 80, 86 are employed owing to the provision of a second set of switches 64 adapted to give an output on a lead fn and on one of leads A<SP>1</SP>-D<SP>1</SP> when one switch is pressed. Output pulses are derived at one time within each cycle of counter 10 when a switch from board 60 is pressed and at another when one at 64 is pressed.

Abstract: 1344080 BCD addition PICO ELECTRONICS Ltd 19 March 1971 11735/71 Divided out of 1344079 Heading G4A Two BCD numbers are added (or subtracted) using binary adders and means for adding (or subtracting) a six. Two 4 bit BCD numbers X and Y are passed through gates 3 at clock time to a binary add/ subtract unit 1 which can receive a carry digit 4 and an add/subtract command 5. The result and carry appear on lines S and C at times # 3 , # 4  respectively. The sum S is in binary code which will differ from BCD if it is more than 9. To convert the binary to BCD it is therefore necessary to add a six if the sum S is greater than 9 (or subtract for subtraction operations). A number forming means 8 produces an output 6 or 0 depending on input 9 which in turn depends on whether S is greater than 9 or not, and the output of means 8 passes to the adder/ subtractor 8 at the same time as the sum S is returned via gate 11. A second addition/sub. traction occurs and the result appears on lines S, C. In subtraction, a negative number is formed in complement form and is recognized by means of its carry. The adder/subtractor comprises four binary adders (Figs. 2, 3, not shown) and all the circuitry may be formed of IGFET's on a single integrated circuit chip. The circuit may be used in a calculator as described in Specification 1,344,079.

IPC: G16B30/00
Filed: 2016-01-18
Abstract: Disclosed is a method to achieve digital quantification of DNA (i.e., counting differences between identical sequences) using direct shotgun sequencing followed by mapping to the chromosome of origin and enumeration of fragments per chromosome. The preferred method uses massively parallel sequencing, which can produce tens of millions of short sequence tags in a single run and enabling a sampling that can be statistically evaluated. By counting the number of sequence tags mapped to a predefined window in each chromosome, the over- or under- representation of any chromosome in maternal plasma DNA contributed by an aneuploid fetus can be detected. This method does not require the differentiation of fetal versus maternal DNA. The median count of autosomal values is used as a normalization constant to account for differences in total number of sequence tags is used for comparison between samples and between chromosomes.
