摘要:
Embodiments of a pixel including a substrate having a front surface and a photosensitive region formed in or near the front surface of the substrate. An isolation trench is formed in the front surface of the substrate adjacent to the photosensitive region. The isolation trench includes a trench having a bottom and sidewalls, a passivation layer formed on the bottom and the sidewalls, and a filler to fill the portion of the trench not filled by the passivation layer.
摘要:
A power supply controller and method for improving the transient response of the power supply controller. The power supply controller includes a pulse width modulation control module connected to a feedback network. The feedback network is composed of an amplifier having an inverting input terminal, a non-inverting input terminal, and an output terminal. A compensation network is coupled between the inverting input terminal and the output terminal of the amplifier and a reference voltage is coupled to the non-inverting input terminal of the amplifier. A switch is coupled between the output terminal of the amplifier and an input terminal of the compensation network. The transient response of the controller is improved by operating the controller in a closed loop compensation configuration during a continuously pulsing operating mode and in an open loop compensation configuration during a pulse skip operating mode.

Embodiments of the invention describe providing high dynamic range imaging (HDRI or simply HDR) to an imaging pixel by coupling a floating diffusion node of the imaging pixel to a plurality of metal-oxide semiconductor (MOS) capacitance regions. It is understood that a MOS capacitance region only turns “on” (i.e., changes the overall capacitance of the floating diffusion node) when the voltage at the floating diffusion node (or a voltage difference between a gate node and the floating diffusion node) is greater than its threshold voltage; before the MOS capacitance region is “on” it does not contribute to the overall capacitance or conversion gain of the floating diffusion node.Each of the MOS capacitance regions will have different threshold voltages, thereby turning “on” at different illumination conditions. This increases the dynamic range of the imaging pixel, thereby providing HDR for the host imaging system.

The present invention provides methods of preventing or treating rheumatoid arthritis using a fully human antibody or antigen-binding fragment thereof that specifically binds human interleukin-6 receptor (hIL-6R). The methods of the present invention may include administration of a second therapeutic agent, such as one or more of a non-steroidal anti-inflammatory drug (NSAID), a glucocorticoid, a disease-modifying anti-rheumatic drug (DMARD), or a TNF-alpha antagonist, T-cell blocker, anti-CD20 antibody, an IL-1, JAK or IL-17 antagonist, or any combination thereof.
摘要:
The present invention provides a method and a device for network communication. The method comprises the steps of translating, by a terminal, IPv6 information into IPv4 information when receiving the IPv6 information from an IPv6 application, and transmitting an IPv6 application request carrying the IPv4 information; and receiving, by the terminal, an IPv6 application response corresponding to the IPv6 application request. The present invention enables free communication between IPv6 applications and services of the other IP address families within an IPv4 network.

The present application is directed to radiolabeled cyclic polyazapeptides, pharmaceutical compositions comprising radiolabeled cyclic polyazapeptides, and methods of using the radiolabeled cyclic polyazapeptides. Such polyazapeptides can be used in imaging studies, such as Positron Emitting Tomography (PET) or Single Photon Emission Computed Tomography (SPECT).

An isolation area that provides additional active area between semiconductor devices on an integrated circuit is described. In one embodiment, the invention includes a complementary metal oxide semiconductor transistor of an image sensor having a source, a drain, and a gate between the source and the drain, the transistor having a channel to couple the source and the drain under the influence of the gate, and an isolation barrier surrounding a periphery of the source and the drain to isolate the source and the drain from other devices, wherein the isolation barrier is distanced from the central portion of the channel.
摘要:
Techniques and architectures for providing a coating for one or more micro-lenses of a pixel array. In an embodiment, a pixel element includes a micro-lens and a coating portion extending over a surface of the micro-lens, where a profile of the coating portion is super-conformal to, or at least conformal to, a profile of the micro-lens. In another embodiment, the coating portion is formed at least in part by orienting the surface of the micro-lens to face generally downward with the direction of gravity, the orienting to allow a fluid coating material to flow for formation of the coating portion.

Processes for fingerprinting a document file and for preventing information leakage are disclosed. Computer apparatus for implementing said processes are also disclosed. For fingerprinting a document, the document is provided and may be normalized. A sequence of hash values are generated for the document. A window size is adaptively determined depending upon the document. Fingerprints for the document are selected from amongst the hash values using the adaptively-sized window. The fingerprints for the document are added to a fingerprint set for content being protected by the information leakage prevention system. For information leakage prevention, suspect documents are processed at the deployment points by extracting fingerprints from the suspect documents and matching the extracted fingerprints against the fingerprints in the fingerprint set. Different fingerprint extraction methods are used at the server and the deployment points. Other embodiments, aspects and features are also disclosed.
