  • Publication number: 20250221062
    Abstract: A pixel cell for an image sensor is described. The pixel cell comprises a photodiode disposed within a semiconductor substrate and a transfer gate coupled to the photodiode. The photodiode includes a shallow doped region and a deep doped region, each having a same conductivity type. The shallow doped region is disposed between a first side of the semiconductor substrate and the deep doped region. The transfer gate includes a vertical portion extending into the semiconductor substrate adjacent to the shallow doped region and from the first side towards the deep doped region of the photodiode. When the pixel cell is viewed from a plan view, the shallow doped region includes a base segment and a protrusion extending from the base segment. The protrusion is separated from the vertical portion by a first lateral separation distance and the base segment is separated from the vertical portion by a second lateral separation distance different from the first lateral separation distance.

  • Patent number: 12336733
    Abstract: The present invention provides a puncture support, including a support body and a soft support coating covering the outside of the support body, wherein a needle insertion channel is provided inside the support body. During use, the puncture support is fixedly connected to an ultrasonic probe by using the hard support body, and the soft support coating attached to the support body is in contact with a human body. Because the support coating is made of a soft material, people feel soft with reduced foreign body sensation when in contact with the support coating. In addition, the support body is made of a hard material, so that the puncture support can be firmly installed, ensuring safety. Therefore, the puncture support can be firmly and reliably installed like an existing puncture support, and also increases the comfort level of the product by taking user feelings into account.

  • Publication number: 20250160805
    Abstract: The present application proposes an illumination assembly, a gear shifting assembly, an electric tube cutting needle. The electric tube cutting needle defines a front end and a rear end of the travel of a winding slider in the winding assembly by means of a detection module and a control module, and achieves an electrified winding operation and excitation reset operation by means of a motor drive module which drives the winding assembly and the excitation assembly, which can ensure that the winding slider stops when the backward movement reaches the rear end during the winding process, as well as that the winding slider stops when the forward movement reaches the front end during the reset process. Compared with the conventional manual tube cutting needles that require manual winding operation, it is more labour-saving and stable, and can improve the efficiency and convenience of the operation of the tube cutting needle.

  • Publication number: 20250136658
    Abstract: Epileptic seizures cannot be effectively controlled in many patients, thereby necessitating the development of novel therapeutic agents. Activation of the A1 receptor (A1R) by endogenous adenosine is an intrinsic mechanism to self-terminate seizures and protect neurons from excitotoxicity. However, targeting A1R for neurological disorders has been hindered by side effects associated with its broad expression outside the nervous system. Herein, the neural-specific A1R/neurabin/RGS4 complex that dictates A1R signaling strength and response outcome in the brain is targeted. A peptide was developed to block the A1R-neurabin interaction and enhance A1R activity. Anticonvulsant and neuroprotective effects are achieved through enhanced A1R function in response to endogenous adenosine in the brain, thus avoiding side effects associated with A1R activation in peripheral tissues and organs.

  • Patent number: 12289927
    Abstract: Image sensors, isolation structures, and techniques of fabrication are provided. An image sensor includes a source of electromagnetic radiation disposed on a substrate, a pixel array disposed on the substrate and thermally coupled with source of electromagnetic radiation, and an isolation structure disposed on the substrate between the source of electromagnetic radiation and the pixel array. The isolation structure can define a first reflective surface oriented on a first bias relative to a lateral axis of the pixel array and a second reflective surface oriented on a second bias relative to the lateral axis. The isolation structure can be configured to attenuate residual electromagnetic radiation reaching a proximal region of the pixel array by pairing a first reflection and a second reflection of the electromagnetic radiation by the first reflective surface and the second reflective surface.
