Abstract: Structures are disclosed for a binned set of two or more pixels of a pixel array that share a same readout circuit. The binned pixel design provides space-saving benefits on the chip and also improves the overall image quality. According to some embodiments, each of the binned pixels includes a photodetector and its own transfer gate. The readout circuit is coupled to the transfer gates of each of the binned pixels and includes its own second transfer gate that separates the pixels from a gain mode select block. The gain mode select block may include capacitors of different sizes and one or more switches to control which capacitors are to receive the charge from any one of the binned pixels. The readout circuit may also include a potential barrier (such as a diode), which allows for pumping charge onto the one or more capacitors of the gain mode select block.

Abstract: A vehicular trailer guidance system includes an electronic control unit (ECU) and a rear backup camera disposed at a vehicle. A human machine interface (HMI) is operable in (i) a trailer left-backup mode, (i) a trailer straight-backup mode and (iii) a trailer right-backup mode. Responsive to selection by the driver of the trailer left-backup mode or trailer right-backup mode, the ECU sets a desired trailer angle of the trailer tongue leftward or rightward to an angle that is commensurate with a driver-selected setting of an input device. Responsive to selection by the driver of the trailer straight-backup mode, the ECU sets the desired trailer angle to a zero degree angle. The ECU, while the vehicle is backing up the trailer, controls the power steering system of the vehicle to steer the vehicle to back up the trailer to have the determined trailer angle coincide with the set desired trailer angle.

Abstract: Image sensor systems are disclosed that include charge coupled device (CCD) pixels integrated with CMOS readout circuitry via separately bonded substrates. According to some embodiments, columns of image sensing pixels on a first substrate are arranged with overlapping gate structures to facilitate charge transfer between the pixels. At least one pixel is coupled to a first conductive pad that contacts (or is melded with) a second conductive pad from a second substrate bonded to the first substrate. The second substrate includes a readout circuit using one or more CMOS devices coupled to the second conductive pad to receive the accumulated charge from a given column of pixels. The resulting photodetector signal from the accumulated charge can be, for instance, amplified via a source follower component and ultimately read out to a column amplifier, and subjected to further processing and/or use in a given downstream system.

Abstract: A method for hepatocellular carcinoma (HCC) subtype classification and treatment may include identifying, for a liver epithelial cell lineage, one or more features associated with the liver epithelial cell lineage. The one or more features may be designated as representative of a molecular subtype associated with hepatocellular carcinoma (HCC) such as, for example, a cholangio-like subtype, a hepatocyte-like subtype, or a progenitor-like subtype. A patient may be determined to exhibit the molecular subtype if these features are detected within the tumor sample of the patient. Moreover, treatment for the patient may be determined based on the molecular subtype exhibited by the patient. For example, treatment for the patient may include additional therapies, such as an GPC3/CD3 bi-specific antibody, to overcome subtype-specific resistance to combination immunotherapy associated with the progenitor-like subtype. Related systems and computer program products are also provided.

Abstract: A given pixel of a pixel array includes various operation modes with each of the operation modes having a different conversion gain for the charge received from the photodetector of the pixel. When the modes are used in conjunction with one another, the dynamic range of the pixel can be increased. A readout circuit coupled to a photodetector within a given pixel includes a transfer gate between the photodetector and a gain mode select block that includes capacitors of different sizes and one or more switches to control which capacitors are to receive the charge from the photodetector. Depending on the state(s) of the one or more switches, different operation modes with different conversion gains can be selected to increase the dynamic range of the pixel. The adaptability of the readout circuit can allow for a high dynamic range even in extreme temperature environments by lowering the dark current.

Abstract: An imaging device may include an image sensor that generates frames of image data in response to incident light with an array of image pixels, and processing circuitry that processes the image data. The processing circuitry may include a transformation circuit that applies transforms to subsampled frames of image data that are generated using a subset of the image pixels to produce transform values, and a comparator circuit that compares the transform values. The processing circuitry may determine that motion has occurred between sequential frames if a difference between a first transform value corresponding to a first image frame and a second transform value corresponding to a second image frame exceeds a threshold value. In response to determining that motion has occurred, the image sensor may generate full-frame image data using all of the pixels of the array of image pixels.
