Abstract: A multi-pixel detector of an image sensor is described. The multi-pixel detector includes a first photodiode region disposed within a semiconductor substrate to form a first pixel, a second photodiode region disposed within the semiconductor substrate to form a second pixel adjacent to the first pixel, and a partial isolation structure extending from a first side of the semiconductor substrate towards a second side of the semiconductor substrate between the first photodiode region and the second photodiode region. A length of a lateral portion of the partial isolation structure between the first photodiode region and the second photodiode region is less than a lateral length of the first photodiode region.

Abstract: The present invention discloses an external terminal protection device for data flow control and a corresponding protection system. The external terminal protection device includes: an interface control module, used for providing a plurality of data interfaces respectively connected to a protected host and one or more external devices; and a system control module, used for monitoring in real time a data transmission state of each data interface in the interface control module, and controlling the data flow of each data interface. The present invention realizes the functions of performing protocol filtering and auditing on various types of data flow without installing flow monitoring and security protection software on the protected host, and achieves the effects of low-latency network auditing and high-reliability protocol filtering, thereby comprehensively eliminating potential security hazards such as Trojan Horse virus implantation and flow anomaly that may be generated by the interfaces.

Abstract: The present invention discloses a hardware control logic based data forwarding control method and a corresponding data forwarding control system. The method includes: externally connecting a terminal protection device to a protected host, and taking over all the data interfaces of the protected host; and controlling by a hardware control logic in the terminal protection device the connection and/or disconnection of a physical circuit corresponding to data forwarding when an external device interacts data with the protected host via the terminal protection device, so as to control the data interaction between the external device and the protected host.
