  • Method and apparatus for congestion control in a data network
    Patent number: 5014265
    Abstract: A method of controlling congestion in a virtual circuit packet network. A initial packet buffer is assigned to each virtual circuit at each node into which incoming packets are stored and later removed for forward routing. If a larger buffer is desired for a virtual circuit to service a larger amount of data, then additional buffer space is dynamically allocated selectively to the virtual circuit on demand if each node has sufficient unallocated buffer space to fill the request. In one embodiment, the criterion for dynamic allocation is based on the amount of data buffered at the data source. In alternative embodiments, the criteria for dynamic allocation may be further based on the amount of data buffered at each node for a virtual circuit and the total amount of free buffer space at each node of a virtual circuit. Signaling protocols are disclosed whereby data sources and virtual circuit nodes maintain consistent information describing the buffer allocations at all times.

  • Illuminative light communication system, lighting device and illuminative light source
    Publication number: 20090297156
    Abstract: Information received from a wired network terminal on the wall face, or the like, is delivered as a light signal from a light transmitting/receiving section of a light communication unit. A lighting fixture is provided with a light transmitting/receiving section where light is received from the light communication unit in order to acquire information, and a light emitting element emits illumination light modulated according to that information. A terminal can acquire the information by receiving the illumination light at a light transmitting/receiving section. Since communication is performed from the light communication unit to the terminal by irradiating light into the space, a convenient illumination light communication system requiring no communication cable or laying work of optical fibers can be constructed.

  • Autonomous robotic telescope system
    Patent number: 8688833
    Abstract: A worldwide network of Autonomous Robotic Telescope Systems (ARTS) tracks and analyzes space objects (satellites, shuttle, space debris, etc.) and astronomical objects (asteroids, comets, supernovas, etc.), and includes the ability to automatically schedule observations using remote, programmable or Internet controllable information networks. The system works with commercial off-the-shelf (COTS) items that include telescopes, mounts, cameras (e.g. CCD), software and computers. The telescope systems operate autonomously and remotely over Internet lines. Automatic scheduling is achieved by programming the slave telescope control computer. Satellite propagators and two line elements necessary for satellite tracking are provided on several Internet sites. Strategically placing these small portable telescope systems around the world enables users to acquire worldwide space object coverage and to be geographically diverse. This is also a cost effective way to provide necessary data to users.

  • Digital communication network architecture for providing universal information services
    Patent number: 4763317
    Abstract: A switched integrated wideband and narrowband multiservices digital network (FIGS. 1 and 2) is an ISDM providing universal information services based on wideband and narrowband voice, data, and video communications. It comprises a plurality of service areas (100, 101), each served by a central switching node (110). The central node is connected to a plurality of remote nodes (103) by feeder optical fibers (107) and a control bus extension (106). Network interface equipment (104) at subscribers' (102) premises is connected to remote nodes by distribution optical fibers (105). Each distribution fiber is wavelength-division multiplexed and carries modulated (pulse-analog, pulse-code, or differential pulse-code) wideband digital channels (205) and a multiplexed channel (206) comprising 32 time-division-multiplexed narrowband digital channels (207). One narrowband channel (207D) carries all signaling messages.

  • Optical communication system with bipolar input signal
    Patent number: 4001578
    Abstract: A bipolar electrical signal of the type transmitted in the T1 digital transmission system is converted into an optical binary signal having pulses and spaces by translating each positive digital "1" in the bipolar signal into two digital pulses, each negative digital 1 in the bipolar signal into two spaces, and the digital 0 in the binary signal into an optical pulse followed by a space. The nonpermitted code of a space followed by an optical pulse is utilized at the receiving location for instantaneous framing. As a result of this particular code conversion, the balanced property of the bipolar input signal is maintained in the optical signal thereby preventing an offset bias from developing at the receiving location in the photodetector. In addition, the bipolar information is maintained in transmission, thus making the optical system "transparent" to bipolar signals.

  • Method and apparatus for generating a converted image with reduced quality degradation resulting from the conversion
    Patent number: 6108443
    Abstract: A digital input output service provides a customer with an image read from a film in the form of an image file. The service generates an image with a photographic print with high restoration precision from this file. When an image is converted from a color space specific to a laboratory system to a standard color space of a personal computer, each pixel value is mapped after the conversion to the sum of the pixel value and a predetermined value, to produce and retain data containing image information of a range wider than the color reproduction range of the original image The data is output to a file together with reference values of the mapping, and the image can be restored in high precision by using this information upon printing.

  • Systems and methods for outlining image differences
    Patent number: 8340409
    Abstract: Methods disclosed permit the outlining of difference images associated with an image pair. In some embodiments, an outlined difference image may be generated by selecting at least one non-zero pixel in a thresholded difference image and setting the value of the selected pixel to the maximum value permitted for that color space. In some embodiments, each color component of the selected pixel may be set to the maximum value permitted for that color component. The outlined difference image may also be scaled while preserving thresholded difference information. In some embodiments, the outlined difference image may be rendered using a monitor or a printer.

  • Watermarking with cone-forest detection regions
    Patent number: 6856693
    Abstract: In a watermarking system, an embedder embeds one of several alternative watermark patterns that represent the source message using side information to improve robustness. A detector uses normalized correlation to test all of the patterns, indicating that the source message is present if any one of the patterns is detected. The detection process results in a detection region that is the union of several disjoint cones, or a cone-forest, in media space.
