摘要:
In a method for processing location holes of a motherboard, a motherboard image of the motherboard is converted into a grayscale image. The grayscale image is normalized and converted into a binary image. Closed contours in the binary image and a minimum circumscribed circle of each of the closed contours are acquired from the binary image. A radius, a circumcenter coordinate and an average pixel value of each minimum circumscribed circle, and an average pixel value of the binary image are calculated. One or more minimum circumscribed circles are selected if each of the selected minimum circumscribed circles has a radius in a predetermined radius range and an average pixel value that is greater than the average pixel value of the binary image.
摘要:
In general, techniques are described for performing distributed network address translation (NAT) with a network device. The network device includes an interface card and a control unit. The interface card receives a packet including a source address. The control unit includes NAT modules. each of which stores a local pool of unallocated NAT resources that have not yet been allocated for use in performing network address translation. The NAT resources each include a network address and a network port number. One of the NAT modules receives the packet, determines whether any of the NAT resources from the local pool of NAT resources are available, in response to the determination that none of the NAT resources from the local pool of NAT resources are available, requests additional NAT resources, and performs NAT to obscure the source address of the packet using one of the additional NAT resources to generate a modified packet. The interface card forwards the modified packet.

摘要:
The present invention provides safe and secure application distribution and execution by providing systems and methods that test an application to ensure that it satisfies predetermined criteria associated with the environment in which it will execute. Furthermore, by using rules and permission lists, application removal, and a modification detection technique, such as digital signatures, the present invention provides mechanisms to safely distribute and execute tested, or untested, applications by determining whether the application has been modified, determining if it has permission to execute in a given wireless device environment, and removing the application should it be desirable to do so.

摘要:
A method of manufacturing dynamoelectric machines includes producing a first plurality and a second plurality of stator and rotor laminations using a die press, forming a first rotor from the first plurality of rotor laminations, and forming a second rotor from the second plurality of rotor laminations. The first plurality and the second plurality of stator laminations have the same inner and outer diameters. The first plurality and the second plurality of rotor laminations have the same inner and outer diameters. The first plurality of rotor laminations have a first magnet slot configuration and the second plurality of rotor laminations have a second magnet slot configuration different than the first magnet slot configuration. The first rotor and the second rotor may have the same or different stack heights. Preferably, a ratio of each stator lamination's inner diameter to outer diameter is at least 60%.
