ISP processes raw pixel data for a frame based on an image processing parameter and provides lines of processed pixel data to control processor via a first interface. For each region of interest (ROI) in the frame, ISP generates auto-exposure and auto-white balance (2A) statistics based on the lines for the ROI and writes them to the local memory via a second interface. Control processor reads 2A statistics from the local memory, determines the image processing parameter based on them, and provides the image processing parameter to ISP. ISP also generates an integer N bin histogram for control processor, which sums a portion of the N total bins and compares the summed bin count to a lighting transition threshold. The image processing parameter is further based on the comparison.

US11275186B2	Imaging devices with capacitively coupled single-photon avalanche diodes An imaging device may include single-photon avalanche diodes (SPADs). Positioning SPADs close together in an imaging device (such as a silicon photomultiplier) may have benefits such as improved sensitivity. However, as the SPADs get closer together, the SPADS may become susceptible to crosstalk. Crosstalk is typically undesirable due to reduced dynamic range and reduced signal accuracy. To reduce crosstalk, a capacitor or other component may be coupled between adjacent SPADs. When an avalanche occurs on a given SPAD, the bias voltage may drop below the breakdown voltage. The capacitor may cause a corresponding voltage drop on a neighboring SPAD. The voltage drop on the neighboring SPAD reduces the over-bias of that SPAD, reducing the sensitivity of the SPAD and therefore mitigating the chance of crosstalk occurring.

US11274156B2	Compositions and methods for targeted immunomodulatory antibodies and fusion proteins The present invention is based on the seminal discovery that targeted immunomodulatory antibodies and fusion proteins can counter act or reverse immune tolerance of cancer cells. Cancer cells are able to escape elimination by chemotherapeutic agents or tumor-targeted antibodies via specific immunosuppressive mechanisms in the tumor microenvironment and such ability of cancer cells is recognized as immune tolerance. Such immunosuppressive mechanisms include immunosuppressive cytokines (for example, Transforming growth factor beta (TGF-β)) and regulatory T cells and/or immunosuppressive myeloid dendritic cells (DCs). By counteracting tumor-induced immune tolerance, the present invention provides effective compositions and methods for cancer treatment, optional in combination with another existing cancer treatment. The present invention provides strategies to counteract tumor-induced immune tolerance and enhance the antitumor efficacy of chemotherapy by activating and leveraging T cell-mediated adaptive antitumor immunity against resistant or disseminated cancer cells.
