International Classification:

H03M 1/12
H03M 3/00

US Classification:

341143, 341172, 341155

Abstract:

An error-corrected representation of an input signal, such as a bioluminescence signal, is generated. An analog representation of the input signal is oversampled and quantized to provide a first-stage digital output and a residual error. The residual error is provided as a second-stage digital output using successive approximation. The first-stage and second-stage digital outputs are used to generate an error-corrected representation of the bioluminescence signal.

Abstract:

Provided herein include various examples of an apparatus, a sensor system and examples of a method for manufacturing aspects of an apparatus, a sensor system. The apparatus may include a die. The apparatus may also include a substrate comprising a cavity. The die may be oriented in a portion of the cavity in the substrate, where the orientation defines a first space in the cavity adjacent to a first edge of the upper surface of the die and a second space in the cavity adjacent to the second edge of the upper surface of the die. The apparatus may further include fluidics fan-out regions comprising a first cured material deposited in the first space and the second space, a surface of the fluidics fan-out regions being contiguous with the upper surface of the die.

International Classification:

H01L 27/146
H01L 23/00

Abstract:

Disclosed in one example is an apparatus including a substrate, a sensor over the substrate including an active surface and a sensor bond pad, a molding layer over the substrate and covering sides of the sensor, the molding layer having a molding height relative to a top surface of the substrate that is greater than a height of the active surface of the sensor relative to the top surface of the substrate, and a lidding layer over the molding layer and over the active surface. The lidding layer and the molding layer form a space over the active surface of the sensor that defines a flow channel.

International Classification:

G01N 30/74
C12Q 1/6874

Abstract:

An apparatus includes a flow cell body, a plurality of electrodes, an imaging assembly, and one or more barrier features. The flow cell body defines one or more flow channels and a plurality of wells defined as recesses in the floor of each flow channel. Each well is fluidically coupled with the corresponding flow channel. The flow cell body further defines interstitial surfaces between adjacent wells. Each well defines a corresponding depth. Each electrode is positioned in a corresponding well of the plurality of wells. The electrodes are to effect writing of polynucleotides in the wells. The imaging assembly is to capture images of polynucleotides written in the wells. The one or more barrier features are positioned in the wells, between the wells, or above the wells. The one or more barrier features contain reactions in each well, reduce diffusion between the wells, or reduce optical cross-talk between the wells.

Abstract:

A system writes input data to a storage device as machine-written polynucleotides; and reads machine written polynucleotides from the storage device as output data. The storage device includes a flow cell including a plurality of storage wells in which machine written polynucleotides may be stored. The storage device may include a set of electrodes corresponding to the storage wells that allow for selective interactions with wells across the surface of a flow cell. Operation of the storage device may include receiving a read request associated with a particular location in the storage device, creating a copy of a nucleotide sequence located at the particular location in the storage device, transferring the copy of the nucleotide sequence to a read location, and reading the copy of the nucleotide sequence at the read location.
