9293 results about "Motherboard" patented technology

A motherboard (sometimes alternatively known as the mainboard, main circuit board, system board, baseboard, planar board or logic board, or colloquially, a mobo) is the main printed circuit board (PCB) found in general purpose computers and other expandable systems. It holds, and allows, communication between many of the crucial electronic components of a system, such as the central processing unit (CPU) and memory, and provides connectors for other peripherals. Unlike a backplane, a motherboard usually contains significant sub-systems such as the central processor, the chipset's input/output and memory controllers, interface connectors, and other components integrated for general purpose use and applications.

Biometric access control and time and attendance network including configurable system-on-chip (CSOC) processors with embedded programmable logic

A biometric access control and time and attendance system comprises an integrated network including one or more remote access devices in electronic communication with a computer database. Each remote access device comprises a silicon chip based system and preferably includes a biometric input device, a liquid crystal display (LCD), computer processing capabilities based on embedded system architecture with configurable system-on-chip (CSOC) technology, and an electrical output for controlling a door lock or the like. The use of CSOC architecture in lieu of conventional personal computer technology (e.g. mother boards, hard drives, video controllers and the like) allows for a more compact and cost efficient design. A plurality of remote access devices is configured for communication with a primary computer database wherein data corresponding to biometric samples for all authorized users is stored. In an embodiment wherein the biometric input devices comprise fingerprint scanners, the devices are configured to facilitate fingerprint identification by incorporating an auto-targeting capability that enables the user to simply place his or her finger on the fingerprint scanner whereafter the system adjusts the scanned image by automatically shifting the scanned image data to a properly targeted position thereby enabling the system compare the scanned print to the biometric samples in the system's data storage memory. Auto-targeting capability eliminates the requirement for manual targeting present in systems of the background art thereby improving system performance and minimizing reliance on human interaction. The present invention contemplates the use of auto-targeting with other biometric systems, such as facial recognition and/or retinal scanning systems, or any other biometric identification technology.

Antenna device for full metal shell

ActiveCN103401059AImprove frequency band coverageSolving Design ChallengesAntenna supports/mountingsRadiating elements structural formsMetallic enclosureRadio frequency signal
The invention discloses an antenna device for a full metal shell. The antenna device comprises a metal shell arranged at the back of communication equipment, antenna branches and feeding points, wherein a metal frame extending from the back of the communication equipment to the side face is arranged around the periphery of the metal shell; the metal shell is segmented and separated into a first metal shell, a second metal shell and a third metal shell; the feeding points are respectively positioned between the first metal shell and the second metal shell and between the second metal shell and the third metal shell; an antenna branch I arranged at the first metal shell and an antenna II arranged at the third metal shell are respectively connected with a radio-frequency signal source of a PCB (Printed Circuit Board) mainboard arranged on the second metal shell, and signals are correspondingly fed in the first metal shell and the third metal shell through the feeding points. With a three-section type full metal shell structure, the metal frame becomes a part of the antenna, the first metal shell and the third metal shell can be used as antennas at the same time, and the antenna device has the advantages of ultra-wide low-frequency band width and high-frequency band width.
