  • Patent number: 7194679
    Abstract: A system for reviewing files which permits comments to be inserted in files to be viewed with a hypertext browser. When the hypertext mark-up language employed is HTML, text files are converted to an HTML representation. An HTML file is represented by a linked list of objects. Comment insertion markers and comment display objects are inserted at predefined points in the HTML linked list representation. The linked list is stored as a binary file and has a comment file associated with it. Access to the HTML file by reviewers and authors causes the regeneration of the HTML document by a Common Gateway Interface which recreates the linked list representation of the document from the binary file and which then generates HTML code from the linked list. Comments may be entered by reviewers working in parallel on the HTML document. Comments are displayed as inserted at the next regeneration of the HTML document by the system.

  • Patent number: 7194195
    Abstract: A system and method for converting information stored on a magnetic medium to DVD format. A tape transport mechanism may sample information stored on a magnetic medium at a selected rate where the selected rate is correlated to an available buffer size in a data processing system. The rate at which information is sampled may be less than the NTSC standard of 30 frames/second thereby requiring less storage to store the digital video representation. The sampled information may be captured and converted into a digital format. The digitized magnetic waveform may be transferred to the data processing system configured to convert the digitized magnetic signals into digitized television waveforms to recover the analog and video content. The digitized television waveforms may then be converted into a digital video representation. The digitized information may then be temporarily stored in the available buffer prior to being compressed and converted into DVD format.

  • Patent number: 7194619
    Abstract: A method, system and computer program product for remotely booting devices. A deployment server may remotely transmit authentication parameter(s), e.g., public key, secret key, to a service unit configured to establish a private connection between server blades and the deployment server. The service unit may remotely install the authentication parameter(s) onto the server blade(s) to be booted by either the deployment server or another boot server. By the service unit remotely installing the authentication parameter(s) onto the server blade(s), the need to manually install them during each network boot operation may be alleviated. By remotely transmitting authentication parameter(s) instead of manually installing them on the devices to be booted during each network boot operation, the deployment server may be able to generate unique authentication parameter(s), e.g., public/private key pair, secret key, for each network boot operation thereby substantially reducing the exposure to replay attacks.

  • Patent number: 7178165
    Abstract: A method, system and computer program product for preventing at least in part a hacker from performing unwanted activities such as in a file system. A security layer may be added in the kernel space configured to determine whether a request to provide a service from a particular user was received from user space or kernel space. If the request was received from user space, then the user is an unauthenticated user. That is, the user may be a potential hacker. Subsequently, the security layer may determine whether the request satisfies requirements for unauthenticated requests. If the request was received from a secure connection manager in kernel space then the user may be treated as an authenticated user. The secure connection manager may be configured to establish a secure authorized connection with an authenticated user. Subsequently, the security layer may determine whether the request satisfies requirements for authenticated requests.

  • Patent number: 7169229
    Abstract: The invention pertains to a coating apparatus and method in which most of the relative movement between a dispensing head and the substrate to be coated is provided by the coating head. The moving head configuration reduces the system footprint and diminishes leveling problems. A powered shuttle mechanism carries a dispensing head above a substrate to be coated while riding on a bearing located underneath the chuck holding the substrate thereby providing rigidity and reducing the system footprint. Chuck support is designed to accommodate anticipated vertical sag in the dispensing head by supporting the chuck at points along its periphery thereby permitting the chuck to sag in conjunction with the dispensing head. The shuttle mechanism is equipped with means for automatically adjusting the height of the dispensing head with respect to substrate to compensate for substrate placement error, substrate dimensional variation, and mechanical drift in the mechanical machine parts.

  • Patent number: 7167982
    Abstract: A method, system and computer program product for securing decrypted files in a shared environment. A filter driver in a kernel space may be configured to control service requests to encrypted files stored in a shared area, e.g., a shared directory on a disk unit, accessible by multiple users. The filter driver may receive a service request to open an encrypted document in the shared area issued from an authorized user. Upon receiving the encrypted data, the filter driver may decrypt the encrypted data. The filter driver may subsequently store the decrypted data in a file in a non-shared area, e.g., a non-shared directory. The non-shared area may be accessible only by the authorized user that requested access to the encrypted file. By storing the decrypted data in a file in the non-shared area, a file once decrypted may be protected in a file sharing environment.

  • Patent number: 7164681
    Abstract: The present invention provides a method for supporting frame priority in a home phone line network. The method includes: detecting a limited automatic repeat request (LARQ) header in a frame with a priority tag; stripping the LARQ header and a frame check sequence (FCS) in the frame with the priority tag; recalculating the FCS for the stripped frame with the priority tag; and adding the recalculated FCS to the stripped frame with the priority tag. The method strips the LARQ header from a HPNA frame with the priority tag before it is sent to an Ethernet controller. By stripping the LARQ header, the Ethernet controller will correctly recognize the priority tag and send the frame to the appropriate priority queue. In this manner, frame priority is supported.

  • Patent number: 7161309
    Abstract: A compensation circuit for protecting a lamp from a large transient current. The compensation circuit may include a saw tooth generator configured to generate a saw tooth signal with an amplitude corresponding to a supply voltage of the lamp. A pulse width modulated signal may be generated by a comparator of the compensation circuit based on the saw tooth signal and a DC signal. The duty cycle of the pulse width modulated signal may be used by a controller to control the duration of time that current flows through the lamp. When the supply voltage of the lamp transitions from a low voltage to a high voltage, the amplitude of the saw tooth signal increases. When the amplitude of the saw tooth signal increases, the duty cycle of the pulse width modulated signal decreases thereby causing the controller to decrease the duration of time that current flows through the lamp.

  • Patent number: 7157036
    Abstract: The present invention provides a method to reduce adhesion between a conformable region on a substrate and a pattern of a mold, which selectively comes into contact with the conformable region. The method features forming a conformable material on the substrate and contacting the conformable material with the surface. A conditioned layer is formed from the conformable material. The conditioned layer has first and second sub-portions, with the first sub-portion being solidified and the second sub-portion having a first affinity for the surface and a second affinity for the first sub-portion. The first affinity is greater than the second affinity. In this fashion, upon separation of the mold from the conditioned layer, a subset of the second sub-portion maintains contact with the mold, thereby reducing the probability that a pattern formed in the conditioned layer becomes compromised. These and other embodiments are described herein.
