Title: Methods for non-invasive prenatal ploidy calling
Inventor: RABINOWITZ MATTHEW
IPC: G16B20/10
Filed: 2011-11-18
Abstract: The present disclosure provides methods for determining the ploidy status of a chromosome in a gestating fetus from genotypic data measured from a mixed sample of DNA comprising DNA from both the mother of the fetus and from the fetus, and optionally from genotypic data from the mother and father. The ploidy state is determined by using a joint distribution model to create a plurality of expected allele distributions for different possible fetal ploidy states given the parental genotypic data, and comparing the expected allelic distributions to the pattern of measured allelic distributions measured in the mixed sample, and choosing the ploidy state whose expected allelic distribution pattern most closely matches the observed allelic distribution pattern. The mixed sample of DNA may be preferentially enriched at a plurality of polymorphic loci in a way that minimizes the allelic bias, for example using massively multiplexed targeted PCR.

Patent CA-2827277-A1 (CA)
Inventor: MARKOVIC GORAN
IPC: G10L19/06
Filed: 2012-02-14
Abstract: An encoding concept which is linear prediction based and uses spectral domain noise shaping is rendered less complex at a comparable coding efficiency in terms of, for example, rate/distortion ratio, by using the spectral decomposition of the audio input signal into a spectrogram comprising a sequence of spectra for both linear prediction coefficient computation as well as spectral domain shaping based on the linear prediction coefficients. The coding efficiency may remain even if such a lapped transform is used for the spectral decomposition which causes aliasing and necessitates time aliasing cancellation such as critically sampled lapped transforms such as an MDCT.

IPC: E21B12/00
Filed: 2013-10-25
Abstract: A centrifugal brake system for retarding shaft backspin includes a brake drum, a brake hub attachable to the shaft and two or more brake shoes mounted on the hub for braking engagement with the drum. A mechanical linkage transfers the generated braking force from the brake shoes to the hub and permits radial displacement of the brake shoes relative to the hub, upon rotational shifting of the hub relative to the brake shoes between deactivated and activated positions. In the deactivated position of the hub, the brake shoes are maintained in a radially inward, disengaged position. In the activated position, the brake shoes are radially displaceable by centrifugal force from the disengaged position to a radially outward, engaged position, wherein the brake shoes are in braking engagement. The rotational shifting of the hub is achieved through frictional drag between the brake shoes and the brake drum.

The syringe subassembly is engagable by the carrier to be moved from its injecting position to a point at which the injection tip is retracted within the housing when the carrier shifts from a first axial position to a second axial position. The at least one latching element is shiftable relative to the carrier from a retracted arrangement to a latching arrangement such that a latch surface of the latching element restricts a size of the passageway to prevent plunger withdrawal. The carrier is liftable within the housing to retract the injection tip into the housing when the at least one plunger is retracted and a latch abutment surface of that plunger engages the latch surface. When the carrier reaches the second axial position, the at least one latching element is shiftable to move the latch surface clear of the latch abutment surface to allow withdrawal of the at least one plunger from the passageway without further lifting of the carrier.
