  • Publication number: 20230421164
    Abstract: In a pipelined Successive Approximation Register Analog to Digital Converter, SAR ADC, a Process, Temperature, and Voltage (PVT)-dependent bias voltage is generated and used to bias the inputs of comparators in at least the first SAR stage and residual amplifier (RA). This achieves a stable biasing and an operating point of the comparators and RA input stages that is independent of PVT variations, by tracking PVT variations in such a way that variations in MOS threshold voltage and drain-source voltage are counteracted. Additionally, a threshold common mode voltage is generated from the PVT-dependent voltage, which controls the amplification duration of the RAs such that the final RA output common mode voltage is substantially equal to the PVT-dependent voltage, which is used to bias the inputs of successive SAR stages. The threshold is set to account for logic delays in terminating the amplification based on the threshold comparison, to achieve the desired common mode amplifier output.

  • Publication number: 20230201441
    Abstract: A peritoneal dialysis (“PD”) system having an air-aided pumping sequence is disclosed herein. In an example, a PD system includes a housing, a PD fluid pump housed by the housing, an airtrap, a fluid line extending from the airtrap, a fluid line valve positioned and arranged to operate with the fluid line, a gas line extending from an upper portion of the airtrap, and a gas line valve positioned and arranged to operate with the gas line. The system also includes a control unit configured to cause the fluid line valve to close, the gas line valve to open, and the PD fluid pump to pump gas from the airtrap into the gas line after a patient drain to create a pocket of gas in the fluid line and push residual used PD fluid towards a drain line.

The genomic nucleotide sequence encoding the SUSIBA2 or SUSIBA2-like transcription factor lacks at least a portion of an activation region of a SUSIBA1 or SUSIBA1-like promote represent in an intron of a wild-type version of the genomic nucleotide sequence encoding the SUSIBA2 or SUSIBA2-like transcription factor. The plant material has a controlled production of carbohydrates, in particular starch or starch and fructan. In particular, the plant material can be designed to produce carbohydrates at enhanced levels.

    Abstract: A system and method for avoiding collisions in a traffic intersection using radar sensors is disclosed. The system detects the location, speed, size, and direction of travel of objects, including vehicles and vulnerable road users, in and approaching a traffic intersection. Using this information, trajectories for all objects are determined, and, if a likelihood of a collision is determined, one or more traffic signal transitions are delayed in an attempt to avoid the collision.

  • Publication number: 20160278382
    Abstract: The invention relates to a method of producing transgenic plant material by transforming a plant with a vector comprising an essential gene having mutations at two sites at least. The method is exemplified with EPSPS as the essential gene. The method makes it possible to use an antisense molecule directed to the native form of said gene for selection of transformed plants. The application relates further to a plant obtainable by the method, a binary vector system containing the mutated essential gene, said mutations being silent mutations. Furthermore, the application discloses the use of an antisense molecule directed to an essential gene as a herbicide in particular using an aqueous solution comprising a saccharide such as sucrose, fructose and glucose.
