摘要： A method and apparatus are provided for operation of an image sensor during signal readout. During a reset operation the gate of a reset transistor coupled to the storage node receives a voltage greater than a threshold voltage to produce a reset of the storage node. During a period where photogenerated charges stored at the storage node are read out the gate of the reset transistor receives a voltage VRST—LOW greater than ground, but less than a maximum voltage which can be stored at the storage node.

摘要： An apparatus for and a method of operating an array of pixels of an image sensor, where each pixel includes at least a photosensor, an associated storage device and a floating diffusion region and the array of pixels is configured in a plurality of rows and columns. The photosensors associated with the pixels are reset and charges are accumulated in the photosensor. The accumulated charges are then globally transferred to storage devices associated with the pixels. A rolling double reset is used to reduce the deleterious effects on the accumulated charges stored in the storage devices. The accumulated charges stored in the storage devices are transferred to floating diffusion regions associated with the pixels and the charges residing in the floating diffusion region are read out. In a second embodiment the storage device is eliminated and the rolling double reset is used to reduce the deleterious effects on the accumulated charges stored in the floating diffusion region.

摘要： A system for initiating and maintaining a real time audio or video media session between two clients, at least one of which has a private network IP address and is supported by a NAT firewall, comprises a proxy server serving each client and a relay server. The first proxy server may receive an invite message from a caller client to initiate a media session with a callee client. The invite message will identify the IP address and media port number of the caller client. The proxy server queries the relay server to obtain a port number of the relay server that may be used for relaying the media session between the caller client and the callee client. The proxy server will replace the IP address and port number of the caller client with the IP address and port number of the relay server in the invite message before forwarding to the callee client. When the callee client generates a response message that includes the IP address and media port number of the callee client, the proxy server will replace the IP address and media port number of the callee client in the response message before forwarding the response message to the caller client.
摘要翻译：一种用于在两个客户端之间启动和维护实时音频或视频媒体会话的系统，其中至少一个具有专用网络IP地址并由NAT防火墙支持，该系统包括为每个客户端和中继服务器提供服务的代理服务器。第一代理服务器可以从呼叫者客户端接收邀请消息以发起与被叫方客户端的媒体会话。邀请消息将标识呼叫者客户端的IP地址和媒体端口号。代理服务器查询中继服务器以获取中继服务器的端口号，该端口号可用于在呼叫者客户端和被叫客户端之间中继媒体会话。代理服务器将在转发给被叫方客户端之前，将邀请消息中的中继服务器的IP地址和端口号替换为主叫方客户端的IP地址和端口号。当被叫客户端生成包含被叫方客户端的IP地址和媒体端口号的响应消息时，代理服务器将在响应消息中替换被叫方客户端的IP地址和媒体端口号，然后将响应消息转发给呼叫方客户。

摘要： In accordance with the invention, a packaged electronic device comprises at least one electronic device and leads sealed within a protective package. The leads comprise a conductive metal substrate having a composite metal finish with a total thickness of 1000 Å or less. The finish comprises, in succession from the substrate, 25-750 Å of palladium alloy and 5-250 Å of wirebondable and solderable material. The substrate is advantageously nickel-plated copper alloy or Fe—Ni alloy. The content of palladium in the palladium alloy coating can range from 10-95 weight percent. This finish meets requirements of wirebonding and solderability at a thickness surprisingly lower than previously used packaging finishes.

摘要： A method of implementing high dynamic range bin algorithm in an image sensor including a pixel array with a first super row having a first integration time and a second super row having a second integration time is described. The method starts by reading out image data from the first super row into a counter. Image data from the first super row is multiplied by a factor to obtain multiplied data. The factor is a ratio between the first and the second integration times. The multiplied data is then compared with a predetermined data. The image data from the second super row is readout into the counter. If the multiplied data is larger than the predetermined data, the multiplied data from the first super row is stored in the counter. If not, the image data from the second super row is stored. Other embodiments are also described.

摘要： This is generally directed to systems and methods for reading optical black pixel cells. For example, in some embodiments, the columns of a pixel array can be shunted together during an optical black pixel readout phase of the imaging system. This may, for example, help improve correction of column fixed pattern noise or other noise. In some embodiments, the column may be shunted together during the optical black pixel readout phase of the imaging system and not shunted during other phases of the imaging system (e.g., when reading values from active pixel cells, barrier pixel cells, etc). In some embodiments, circuitry for providing the column shunting can be implemented as an independent block of the imaging system. In other embodiments, this circuitry can be implemented within other blocks of the imaging system. As an illustration, the shunting circuitry can be implemented within a VLN block of the imaging system.
