Abstract: A discrete-time delay (TD) technique in a baseband receiver array is disclosed for canceling wide modulated bandwidth spatial interference and reducing the Analog-to-Digital Conversion (ADC) dynamic range requirements. In particular, the discrete-time delay (TD) technique first aligns the interference using non-uniform sampled phases followed by uniform cancellation using a cancellation matrix, such as, for example, a Truncated Hadamard Transform implemented with antipodal binary coefficients.

Abstract: Aspects of the invention provide methods and systems for moving moveable stages relative to a stator. A stator is operationally divided into multiple stator tiles. The movement of the one or more moveable stages is controlled by a plurality of controllers (each assigned particular control responsibilities). A controller is provided for each stator sector, where each stator sector comprises a group of one or more stator tiles. Controllers from neighboring sectors share various information to facilitate controllable movement of one or more moveable stages relative to the stator.
Abstract: Methods, devices and systems for analyzing precious samples of cells, including single cells are provided. The methods, devices, and systems in various embodiments of the invention are used to assess genomic heterogeneity, which has been recognized as a central feature of many cancers and plays a critical role in disease initiation, progression, and response to treatment. The methods devices and systems are also used to analyze embryonic biopsies for preimplantation genetic diagnosis (PGD). In one embodiment, the devices, systems and methods provided herein allow for the construction of genomic and RNA-seq libraries without a pre-amplification step.

Abstract: Disclosed herein are fluidic mixers having bifurcated fluidic flow through toroidal mixing elements. The mixers operate, at least partially, by Dean vortexing. Accordingly, the mixers are referred to as Dean Vortex Bifurcating Mixers (“DVBM”). The DVBM utilize Dean vortexing and asymmetric bifurcation of the fluidic channels that form the mixers to achieve the goal of optimized microfluidic mixing. The disclosed DVBM mixers can be incorporated into any fluidic (e.g., microfluidic) device known to those of skill in the art where mixing two or more fluids is desired. The disclosed mixers can be combined with any fluidic elements known to those of skill in the art, including syringes, pumps, inlets, outlets, non-DVBM mixers, heaters, assays, detectors, and the like.
