  • Patent number: 7618808
    Abstract: Disclosed are an apparatus and a method for remotely monitoring and controlling various processes in an incubation/reaction system. Remote control is accomplished via computer network protocol. In a disclosed preferred embodiment, remote observation and control is accomplished via a “web server” program running on a computer attached to or embedded within the body of the system, interfacing with temperature monitoring and control means, digital video camera photomicroscope means, atmospheric monitoring and control means, and other devices for monitoring or affecting contents of the system. The web server sends data to and receives data from any computer running a “web browser” program. Bi-directional communication is possible over secured and unsecured channels and can penetrate firewall software to allow real-time communication between a user and a chamber when each is behind a different firewall.

  • Patent number: 5994946
    Abstract: The invention provides a method and system for reducing capacitive coupling for transmission lines. Where there is a plurality of parallel transmission lines, a first half of the transmission lines (every second one) are inverted at their driving points, and are reinverted at a half-way point between their driving points and their receiving points, using an inverter placed halfway along the transmission line. A second half of the transmission lines are inverted at the half-way point, and are reinverted at their receiving points. Thereby, every second one of multiple transmission lines is inverted at any point in the transmission line, causing capacitive coupling to self-cancel across the entire transmission line, reducing crosstalk and speeding rise time.

  • Patent number: 5987153
    Abstract: The invention provides a method of and system for automated verification and prevention of spoofing for biometric data, such as handwritten signatures. Biometric data known to be true, such as signatures already entered by the authentic person, are recorded and compared against test biometric data, such as a test signature entered by a person seeking authentication. The test biometric data is compared against the known biometric data, and is accepted only if the test biometric data is sufficiently "close" to the known biometric data, but not so close as to indicate that known biometric data was recorded and played back for the test. The test biometric data represents a handwritten signature given contemporaneously by the person seeking access, and is verified against a set of template signatures earlier given by at least one authorized person.

  • Patent number: 5956409
    Abstract: The invention provides a method of and system for secure application of seals. An optical image of a seal is recorded by a computer and encrypted using a key for encryption generated in response to template biometric data from authorized persons. When a person seeks to use the seal, for example to apply the seal to a document, test biometric data is input from that person and used to generate a key for decryption. If the test biometric data matches the template biometric data, the key for decryption will be useful for decrypting the encrypted seal, and the person seeking access to the seal. The test biometric data represents a handwritten signature given contemporaneously by the person seeking access, and is verified against a set of template signatures earlier given by at least one authorized person. Specific signature features are determined in response to the template signatures and used for generating one or more keys for encrypting the seal.

  • Patent number: 5818468
    Abstract: A method for decoding and displaying video signals using a memory buffer, in which a speed of a write operation for a memory buffer is adjusted to avoid overtaking a read operation for the same memory buffer. A display controller and a video MPEG engine contend for access to a DRAM memory buffer controller, and have their relative priorities set so that the video MPEG engine operates to write to the memory buffer at a relatively slow speed during a time period when the display controller is reading from that same memory buffer, and to write to the memory buffer at a relatively fast speed during a time period when the display controller is not reading from the memory buffer. The relatively slow speed is preferably much slower than the reading speed of the display controller, while the relatively fast speed is preferably much faster than the display controller.

  • Patent number: 5802042
    Abstract: The invention provides a method and system for auto-sensing LMI protocols in frame relay networks. When a router is first coupled to a frame relay network, it automatically configures the local management interface (LMI) to use one of a selected set of possible LMI protocols, by generating a set of protocol requests for a plurality of protocols, and by thereafter simultaneously listening for protocol responses from the configuration server. Multiple valid responses from the configuration server are assigned priority in response to which valid response is last to arrive.

  • Patent number: 5797029
    Abstract: An improved audio-output device coupleable to a computer system, in which a DSP operating under software control emulates a common command interface. The command interface has a set of registers that are made available to the CPU for reading and writing, even if there are no such physical registers available in the device. The DSP also performs tasks in addition to audio-output, even though the audio-output device is required to respond immediately to commands from the CPU. The audio-output device has a DSP for interpreting and executing commands received from the CPU, a local memory for storing data input to or output from the DSP, a bus-interface (BIF) element for coupling the DSP and memory to a system bus, and a direct memory access (DMA) element for transferring data between the local memory and the system bus.

  • Patent number: 5793419
    Abstract: A personal surveillance system having a video camera and an audio microphone in a single package sufficiently small to be worn as a badge, lapel pin, or similarly small accessory. The audio/video package is coupled to a transmitter for transmitting an audio and video signal to a remote station. The remote station comprises a video cassette recorder responsive to a signal for recording that is generated on a continuous basis by the audio/video package in a signal band that is filtered before recording.
