| 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. Many circuits need no trimming when targeted for the typical process. | 07-07-2011 |

The cutoff value may also be determined based on an average concentration of a sequence per reaction. In one aspect, the cutoff value is determined from a proportion of informative wells that are estimated to contain a particular nucleic acid sequence, where the proportion is determined based on the above-mentioned percentage and/or average concentration. The cutoff value may be determined using many different types of methods, such as sequential probability ratio testing (SPRT). | 04-02-2009 |
| 20090155776 | Fetal methylation markers - This application describes the discovery that, in a pregnant woman, certain genes (such as RASSF1A, APC, CASP8, RARB, SCGB3A1, DAB2IP, PTPN6, THY1, TMEFF2, and PYCARD) originated from a fetus are highly methylated, whereas the same genes of maternal origin are unmethylated. This discovery allows the easy detection of one or more of these methylated fetal genes in a biological sample from a pregnant woman, serving as a universal indicator of the presence of fetal DNA in the sample. These fetal methylation markers are particularly useful as positive controls for a non-invasive analytical process during which the quality and quantity of fetal DNA are monitored.

The determination of the relative amounts may count sequences of only certain length. A parameter derived from these amounts (e.g. a ratio) is compared to one or more cutoff values, thereby determining a classification of whether a fetal chromosomal aneuploidy exists. Prior to sequencing, the biological sample may be enriched for DNA fragments of a particular sizes. | 05-06-2010 |

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. | 05-05-2011 |

| 20110276277 | SIZE-BASED GENOMIC ANALYSIS - 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. | 11-10-2011 |

| 20090196589 | CAMERA WITH DOUBLE CASSETTE FILM SYSTEM - Aspects of the invention are directed to a camera with double cassette system (DCS) film. The camera and DCS film are configured to allow only a specific type of DCS film to be used in the camera and to prevent reuse of the secondary cassette of the DCS film. To such end, the second chamber of the camera can include one or more protrusions therein. The protrusions can extend from the upper and lower end walls of the second chamber. In one embodiment, there is a first protrusion associated with the upper end wall and a second protrusion associated with the lower end wall. In order to properly set in the second chamber, a secondary cassette of a DCS film system includes recesses that can receive at least a portion of a respective protrusion. To prevent reuse of the secondary cassette, it constituent shells can be welded together. | 08-06-2009 |
| 20110180341 | PEDAL DRIVEN APPARATUS HAVING A MOTOR - A hybrid bicycle is provided which can be manually propelled, but which includes a motor unit for also causing forward propulsion of the bicycle. The bicycle comprises manually operable pedals fixed for rotation with a pedal spindle for receiving a manually provided driving force and a motor having a shaft for receiving a motor provided driving force. A first torque transmission path is provided for transferring the manually provided driving force to a sprocket of the pedal driven apparatus and a second torque transmission path is provided for transferring the motor provided driving force to said sprocket of the pedal driven apparatus. A first one way drive means is also provided. This is provided in the first torque transmission path between the pedal spindle and the sprocket such that when the sprocket is being driven by the motor provided driving force through the second torque transmission path, the pedal spindle is able to freewheel. The second torque transmission path may include a gear mechanism mechanically coupling the motor shaft to the sprocket of the pedal driven apparatus. The gear mechanism has a reduction gear ratio and operates to transfer the motor provided driving force from the motor shaft to the sprocket at said reduction gear ratio. The motor may be arranged concentrically around a pedal spindle of the pedal driven apparatus such that the pedal spindle is freely accommodated through a hollow bore of the motor shaft and such that their axes of rotation are parallel and preferably co-incident. | 07-28-2011 |
| 20110183793 | Pedal Driven Apparatus Having a Motor - A hybrid bicycle is provided which is manually propelled, but may include a motor unit for assisting forward propulsion of the bicycle. The bicycle has a control system for providing a control input for another component of the bicycle. Where that component comprises the motor, the control input is for increasing drive power applied by the motor unit to said bicycle. Where the component is a continuously variable transmission (CVT) for the bicycle, the control input is for continuously varying the gearing ratio of the CVT. Located adjacent a drive sprocket is a moveable plate member. 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 |
