The emergency escape device has the advantages that under emergency situations, indoor staff can open the security windows within 15s, and the emergency escape device is fast in emergency, high in reliability, convenient to operate and independent of electric power.

The blood vessel recognition method and device is a method for quickly identifying and identifying people with biometric technology, and its operation steps are as follows: a. Blood vessel texture image acquisition: irradiate the collected blood vessel parts with near-infrared auxiliary light, and collect blood vessel texture images ; b. Preprocessing of image texture: use the standard deviation threshold tracking method to separate the background, determine the foreground and background of the image, and then perform binary denoising and refinement; c. The authentication problem is transformed into a point pattern matching problem; d. Establishing a database: when building a file, the point coordinates of the singular point position 转化为 Store the polar coordinates in the database as a file template; e. Feature matching: according to the principle of first locking the reference position and then comparing, when comparing blood vessel textures, use the template stored in the database above and the user PID number to form Original feature data template.

The invention belongs to the technical field of computers, relates to a security computer, and particularly relates to a double-host security computer based on a satellite system. The double-host security computer comprises hosts and an enclosure, wherein the number of the hosts is two, and the hosts are respectively a secrecy-involved host and a non-secrecy-involved host, the two hosts are isolated by a way of physical shielding isolation, the secrecy-involved host and the non-secrecy-involved host are respectively connected with a physical switcher, the physical switcher is connected with an intelligent plate, and the intelligent plate controls the interconnection and data transmission of components through a PCI-E bus. The computer disclosed by the invention both can be applied to the industrialized production of integrated desk computers and the industrialized production of portable computers, and has a triple illegal-start-preventing function, a one-way information transformation function and a power-cut active or passive self-destruct preventing function, and the like, therefore, the double-host security computer has a good application prospect in the technical field of computers, and makes contributions to departments such as party and government organizations, military departments, national defense departments, scientific research institutions and the like.

The invention discloses an access control system for the cockpit door of an aircraft and the aircraft. The access control system includes an independently operated main latch device and a backup latch device, a controller, a verification device located on one side of the passenger compartment, and a verification device located on the cockpit. Pilot's control panel on one side. Wherein, the backup latch device is an electromagnetic lock assembly, and the controller communicates with the verification device and the pilot control panel, and the verification device is preset with first and second verification information. The controller can send an unlock request to the pilot control panel in response to the first verification information input through the input interface, and control the electromagnetic lock assembly and / or main latch mechanism unlocked. According to the access control system for the cockpit door of the aircraft and the aircraft of the present invention, the risk of hijacking by a single pilot can be completely eliminated while realizing the function of preventing cabin occupants from illegally entering the cockpit.

The invention relates to a sash-shielding and energy-saving broken bridge aluminum alloy window. The sash-shielding and energy-saving broken bridge aluminum alloy window comprises a window frame body and a window sash, wherein a framework of the window sash is formed by a plurality of window sash profiles; a window sash groove is formed in the window frame body and is provided with the outer wall and the side wall; the outer wall of the wind sash groove is arranged on the outdoor side of the window frame body; a window sash opening is formed in the outer wall of the window sash groove; an opening in the indoor side of the window sash groove is larger than the window sash opening; the window sash is inserted into the window sash groove; the inner edge of the window sash framework corresponds to the window sash opening, so that the window sash framework is shielded in the window sash groove outside the room.
