  • Patent number: 6793526
    Abstract: A stacked connector includes a base dock connecting to an electric circuit. The base dock has an insert member mounted thereon. The insert member includes at least two insert slots and is encased by a metal shell from outside. The rear side of the insert member is coupled with a transfer connection circuit. The base dock has connection terminals directly connecting to the electric circuit. The connection terminals in each insert slot are extended to the rear side of the insert member to connect to the transfer connection circuit. Thereby the length of the connection terminals may be reduced to lower the cost and enhance the structural sturdiness and reduce interference between the terminals.

  • Publication number: 20040148509
    Abstract: A method and system that generates a secret from individual's biometric information, such as voice, handwriting and fingeprint. It extracts a feature vector from the captured biometric data. The feature vector is then transformed into a codewood, and the codeword is used to construct the secret. A one-way hash of the secret is stored. Only if a user generates a new secret that has the same hash value as that stored will the user be confirmed. To keep pace with the gradual change of the measured biometric features, the a secret can be updated adaptively. The secret may be an encryption key.

  • Patent number: 6731996
    Abstract: A method of fabricating an article from a blank of material (e.g., aluminum alloy sheet) having anisotropic deformation properties, with tooling which has been designed by predicting flow and deformation of the blank using an analysis which decouples the anisotropic deformation properties of the blank. The method calculates the response of a small amount of the blank using crystal plasticity theory. The blank can be represented as a mesh having a plurality of elements. A strain path is predicted for each element using finite element analysis (FEA), and a stress-strain curve is defined for each element by performing a material point simulator (MPS) calculation for each element using its respective strain path. A second FEA is then carried out on the elements using the respective stress-strain curve for each element. The stress-strain curve for each element may be defined by assigning to each element a curve which lies between an upper bound curve and a lower bound curve, using various methods.

  • Patent number: 6711553
    Abstract: A method, apparatus and a computer program product are described for copy protecting encrypted documents in a client-server system using an unsecured communication channel. The client-server system has clients and a server for storing encrypted documents. Encrypted documents e(Ks, M) are received by a client from the server. Communications on a transmission channel between the client and the server are then authenticated. Such communications also include electronic payments initiated by a user using the client. Upon authenticating or payment, an encrypted document can then be decrypted. After decrypting, the unencrypted document is displayed but prevented from storage at any client unless re-encrypted using a host specific key KH associated with the client to thereby provide a re-encrypted document.
