  • Patent number: 7281125
    Abstract: A method, computer program product and computer system for securing alterable data. A computer that is remotely managed may be equipped with a protected storage that is accessible only by BIOS code. The protected storage may have the capacity to store a symmetrical encryption key. An EEPROM, which normally contains the BIOS code, may be used to store accessible configuration data as well as remotely unaccessible sensitive access information (e.g., passwords). The remotely unaccessible sensitive data is encrypted with the symmetrical encryption key by the BIOS code. Remote access to the sensitive data is accomplished via change requests submitted to the BIOS code over a secure channel. The BIOS code then determines whether the request is valid. If so, then sensitive data is decrypted, altered, encrypted, and re-written into the EEPROM. Normal access to accessible data is unaffected and remote access is allowed without changing the computer system architecture.

  • Patent number: 7281010
    Abstract: The present invention addresses the foregoing need by creating two identically structured storage trees with a single storage root key. As envisioned in the current art (e.g., the TCPA specification), all migratable keys will be stored in a migratable storage tree. These migratable keys will be storage keys except at the extreme end of any branch, where the key (known as a leaf key) will be a user key. However, an additional storage tree will also be created which shadows the migratable storage key. This second storage tree will be comprised entirely of non-migratable storage keys of the quicker loading type except for the leaf keys (which will be identical to the leaf keys in the migratable storage tree (MST). The second storage tree (SST) will have a storage key for every migratable storage key in the MST. The use authorization for the keys in the SST will be identical to the use authorization for the MST.

  • Patent number: 7265174
    Abstract: The disclosure provides compositions prepared by combining nanomaterials with a halide-containing polymer, thereby forming a combined polymer matrix having dispersed nanomaterials within the matrix. The nanomaterials may be carbon-based nanotubes, in some applications. A halide-containing monomer is combined with nanotubes, and then polymerized in some compositions. In other applications, a halide-containing polymer is solution processed with nanotubes to form useful compositions in the invention. Also disclosed are probes for near field detection of radiation.

  • Publication number: 20070203776
    Abstract: A method and apparatus for storing a resume on a server which is part of a computer network (e.g. the Internet), providing a method for the owner of the resume (job candidate) to mask out certain confidential information (such as the owner's identity) while maintaining the “look and feel” of the original resume, and allowing users on the network the freedom to peruse an exact copy of the resume at will, while keeping the confidential parts (e.g. the owner's identity and current employer) sufficiently blurred out that they would be undecipherable. This system would also provide for a method in which any user on the network (i.e. the Internet) who wanted to view the unmasked version of the resume would be granted the ability to send a confidential request directly to the owner of the resume (job candidate) over an Internet-based application for permission to view the entire (unmasked) resume.

  • Patent number: 7242768
    Abstract: A method for providing security with a secure chip, includes: creating a migratable keyblob using a first random number, where the migratable keyblob contains a key; wrapping the migratable keyblob with a public key of the key's parent key; encrypting the first random number with a pass phrase for a user of the key; storing the encrypted first random number; and migrating the migratable keyblob from the computer to itself. If the private key of the secure chip is stolen, the thief can only unwrap keys which are ancestors of the key in the migratable keyblob. To obtain the key in the migratable keyblob, the random number used to create it is required. However, the pass phrase of the user is required to decrypt it. This increases the security of the key stored in the migratable keyblob and its children keys.

  • Patent number: 7235906
    Abstract: The present invention provides a linear, rotary spherical motor with an integrated magnetic bearing. The motor can be a toothless permanent magnet, BLDC design composed of a permanent magnet rotor and a Zigzag stator winding containing at least two-phase windings, where each phase is constructed of at least two circuits. Other exemplary embodiments include a trapezoidal winding configuration. The individual circuits of a phase are displaced away from each other along a line that is at right angles to the direction of the alternating polarity magnet array. The circuits forming a phase share the same “slot”, and each circuit resembles a complete phase winding, however each circuit contains a proportion of the total number of turns of the phase. Controllable axial bearing force is developed through the differential balance of the currents in the circuits, while required motor torque is generated by the sum of the individual currents in a given phase.

  • Publication number: 20070136064
    Abstract: A mobile personal computer including a case, a display device, a speech recognition system, a movement sensor, a microprocessor, and a power source. The case is sized for handling by a single, adult human hand and maintains the various other components. The display device is adapted to generate a displayed image. The speech recognition system includes a microphone for collecting sound waves generated by a user's speech. The movement sensor is mounted to the case and is adapted to generate spatial-related information of the case relative to earth. The microprocessor is electronically connected to the display device, the speech recognition system, and the movement sensor. The microprocessor utilizes a personal computer operating system to perform computing operations, and is adapted to transition from a first operational mode to a second operational mode in response to information signaled from the movement sensor.

  • Patent number: 7194762
    Abstract: A method for providing security in password-based access to computer networks, the network including a server and a remote user, includes: signing a phrase by a security chip of the server using an encryption key; associating the signed phrase with the remote user; signing the phrase with an encryption key obtained by the security chip when a request for access to the computer network is received from the remote user; comparing the phrase signed with the obtained encryption key with the signed phrase associated with the remote user; and granting access to the remote user if the phrase signed with the obtained encryption key is the same as the stored signed phrase associated with the remote user. The use of the encryption key protects against “dictionary attacks”. Use of the security chip protects against offline attacks. These provide greater security for the computer network.

    Abstract: An automatic coupling system (10) for a locomotive (11). The automatic coupling system includes a means for detecting a coupling contact and for controlling locomotive systems such as throttle and brakes in response to such contact. The means for detecting contact may be a speed sensor (24), an accelerometer (26), a distance detector (28), and/or a wheel slip detector (30). The automatic coupling system may be integrated with a locomotive remote control system (22) to facilitate the coupling of a locomotive to a railcar (40) when the operator is not located in the locomotive cab.
