20110163799 | Bi-directional Trimming Methods and Circuits for a Precise Band-Gap Reference - A bandgap reference circuit has trimming-up resistors and trimming-down resistors for bi-directional trimming. PNP transistors have base and collectors grounded and emitters connected to parallel resistors. A difference resistor drives an inverting input of an op amp that drives a transistor that generates the bandgap reference voltage Vbg. A sensing resistor connects Vbg to a splitting node that connects to the non-inverting input through a first parallel resistor. The splitting node also connects through a second parallel resistor to the inverting input. Fuses or switches enable the trimming-up and trimming-down resistors. The trimming-up resistors are in series with the sensing resistor and the trimming-down resistors are in series with an output resistor that connects Vbg to reference voltage Vref. The circuit can be designed for a more typical process since bi-directional trimming allows Vref to be raised or lowered.

For a given sample, a first value of a size parameter can be determined from the sizes of DNA fragments in a sample. A comparison of the first value to the calibration data points can provide the estimate of the fractional concentration of the clinically-relevant DNA. | 09-12-2013 |
20130323731 | DETERMINATION OF THE DEPTH COVERAGE OF THE FETAL GENOME - Systems, methods, and apparatus for determining at least a portion of fetal genome are provided. DNA fragments from a maternal sample (maternal and fetal DNA) can be analyzed to identify alleles at certain loci. The amounts of DNA fragments of the respective alleles at these loci can be analyzed together to determine relative amounts of the haplotypes for these loci and determine which haplotypes have been inherited from the parental genomes. Loci where the parents are a specific combination of homozygous and heterozygous can be analyzed to determine regions of the fetal genome. Reference haplotypes common in the population can be used along with the analysis of the DNA fragments of the maternal sample to determine the maternal and paternal genomes. Determination of mutations, a fractional fetal DNA concentration in a maternal sample, and a proportion of coverage of a sequencing of the maternal sample can also be provided. | 12-05-2013 |
20140045181 | DETERMINING PERCENTAGE OF FETAL DNA IN MATERNAL SAMPLE - Methods, systems, and apparatus are provided for determining whether a nucleic acid sequence imbalance exists within a biological sample. One or more cutoff values for determining an imbalance of, for example, the ratio of the two sequences (or sets of sequences) are chosen.

The percentage of fetal DNA can be calculated from the same or different data used to determine the cutoff value, and can use a locus where the mother is homozygous and the fetus is heterozygous. The cutoff value may be determined using many different types of methods, such as sequential probability ratio testing (SPRT). | 02-13-2014 |
20140080715 | NON-INVASIVE DETERMINATION OF METHYLOME OF FETUS OR TUMOR FROM PLASMA - Systems, methods, and apparatuses can determine and use methylation profiles of various tissues and samples. Examples are provided. A methylation profile can be deduced for fetal/tumor tissue based on a comparison of plasma methylation (or other sample with cell-free DNA) to a methylation profile of the mother/patient. A methylation profile can be determined for fetal/tumor tissue using tissue-specific alleles to identify DNA from the fetus/tumor when the sample has a mixture of DNA. A methylation profile can be used to determine copy number variations in genome of a fetus/tumor. Methylation markers for a fetus have been identified via various techniques. The methylation profile can be determined by determining a size parameter of a size distribution of DNA fragments, where reference values for the size parameter can be used to determine methylation levels. Additionally, a methylation level can be used to determine a level of cancer. | 03-20-2014 |
20140080720 | FETAL GENOMIC ANALYSIS THAT ACCOUNTS FOR GC BIAS - Systems, methods, and apparatuses for performing a prenatal diagnosis of a sequence imbalance are provided. A shift (e.g. to a smaller size distribution) can signify an imbalance in certain circumstances. For example, a size distribution of fragments of nucleic acids from an at-risk chromosome can be used to determine a fetal chromosomal aneuploidy. A size ranking of different chromosomes can be used to determine changes of a rank of an at-risk chromosome from an expected ranking. Also, a difference between a statistical size value for one chromosome can be compared to a statistical size value of another chromosome to identify a significant shift in size. A genotype and haplotype of the fetus may also be determined using a size distribution to determine whether a sequence imbalance occurs in a maternal sample relative to a genotypes or haplotype of the mother, thereby providing a genotype or haplotype of the fetus. | 03-20-2014 |

The plate member and the drive sprocket are mounted for rotation about an axis of rotation of a pedal spindle, although the sprocket is not fixed for rotation with the pedal spindle. The drive sprocket is loosely coupled to the plate member with the plate member being moveable relative to the sprocket by a limited distance in a rotational direction. The plate member acts on a lever mechanism when it is moved relative to said drive sprocket such that any movement of the plate member results in an axial movement of an actuator member which triggers the control system to generate the control input in response to the amount of any movement of the plate member relative to the sprocket. | 07-28-2011 |
20120165150 | MOTOR HAVING AN AUXILIARY DRIVEN SHAFT - A motor unit comprises a motor shaft for receiving a motor provided driving force and an auxiliary shaft for receiving an externally provided driving force.
