Patent EP-0735656-A2 (EP)
Inventor: CANTER STANLEY
IPC: H02M3/157
Filed: 1996-03-28
Abstract: A multi-slice power converter (10) employs a digital circuit (22) to generate phase-delayed pulse width modulated (PWM) signals, which results in the duty cycle of the PWM signals having only a certain number of possible values. The quantization of the duty cycle is shown to result in two types of instabilities which are unique to power converters having a digital control loop, in addition to the conventional analog-type of instabilities. This invention provides novel methods and apparatus for stabilizing the digital control loop of the power converter through the use of a periodic dither signal having a frequency that is less than the PWM frequency and greater than a bandwidth frequency of the converter. The dither signal functions to effectively increase the number of possible duty cycles by a factor given by the ratio of the dither frequency to the bandwidth frequency.

Abstract: An optical receiving circuit comprises a photo-detector (1), a differential transimpedance amplifier (2), a peak detector (6), a resistor network (4) circuit and a discriminator (3). The transimpedance amplifier (2) receives a current pulse converted by the photo-detector (1) and outputs a non-inverting voltage signal and an inverting voltage signal of the same level. A peak detector (6) for detecting a peak value of the non-inverting voltage signal. A resistor network circuit (4) make an additional operations between an output signal from the peak detector (6) and the inverted voltage signal, and between the non-inverting voltage signal and the non-inverting voltage signal, thereby generating two complemental voltage signals, which have the same amplitude and cross each other at a middle point of the amplitude. The discriminator (3) discriminates a crossing potential at which the two complemental voltage signals generated by the resistor network circuit (4) and generates a pulse-shaped signal with a logical level whose state is changed to another logical state at the crossing potential.

Abstract: A fluorescent lamp includes a lamp tube (14) having first and second ends (14A,14E) and containing fill materials for causing light generation when provided with electrical power. The lamp further includes first and second power-transferring means (41,42) at the first and second ends of the lamp tube, respectively, for providing the fill materials in the lamp tube with electrical power. Also included is a thermal heat shield (16) separating the first power-transferring means from ballast circuitry (18) which supplies power to the first power-transferring means and which has a lifetime that becomes substantially less as its operating temperature increases. The thermal heat shield is constructed so that it reflects back to the first power-transferring means and any adjacent portion of the lamp tube sufficient radiant energy to reduce the operating temperature of the ballast circuitry by more than about one degree Celsius compared with the absence of the heat shield.

Abstract: The images of an object taken at a plurality of viewpoint positions are input together with information indicating the plurality of viewpoint positions, and the viewpoint position of an observer is detected. One of the input images is selected on the basis of the detected viewpoint position of the observer, and the scan line of the image is determined in accordance with the viewpoint position of the observer and the viewpoint position upon taking the selected image, thereby generating an image from the viewpoint position of the observer. In this manner, distortion of the image to be generated is suppressed. On the other hand, input multi-viewpoint images are converted into light rays that travel in a space, and each light ray is stored in a light space corresponding to a plane, which is one of a plurality of radially arranged reference planes and has an angle the plane makes with the light ray, which angle is closest to right angles. On the basis of the image, pixel positions, and pixel values calculated from the stored light rays, a desired image is generated, thereby broadening the observation range within which movement of the viewpoint position is allowed, and suppressing the required data volume.

Abstract: A computer connected to a network has a cumulative packet count
data structure that resides in the memory of the computer and has one or
more records. Each of the records has usage information associated with
an entity (a user or service provider with one or more other computers)
connected to the network. The information is in terms of one or more
information units, e.g. packets, cells, bytes, and bits. An incrementing
process, executed by the central processing unit of the computer accesses
a polled amount in a router on the network. The polled amount indicates
an amount of network usage associated with the entity in terms of the
information units used over a polling period. The incrementing process
increments the usage information with the polled amount so that the usage
information indicates a cumulative amount of network usage by the entity
over a time period. The network usage can be weighted by various
(network) cost factors. The weights can also be used to distribute or
allocate (weighted) usage among the various entities on the network.

Abstract: A system for securely providing restricted display
information having an encoder transmitter for transmitting
selected update data using information identification codes
as enabling reception keys and a plurality of uniquely
identified decoder-receivers for receiving the update data
for display or a video screen. Authorized decoders are
provided with enable reception keys so that subsequently
transmitted data having an information identification code
matching a reception key at a decoder-receiver may be
retrieved for subsequent display on the video screen.
Symbolic signaling is used so that enabling a decoder-receiver
with a reception key also provides display
coordinate information for displaying the update data in the
proper relative display location for the video screen of
that enabled decoder, so that the update data subsequently
transmitted is displayed using that display coordinate
information. Tile messaging and cellular micrographic
transmission techniques are used to reduce the volume of
data transmitted to changed update data, wherein cells of
characters are transmitted as one byte of data and cells of
pixel data are transmitted a plurality of bytes of data.
Each decoder-receiver may have a plurality of video screens
separately and uniquely identified such that encoded update
data and other messages are transmitted for specific video
screens. The system includes multiplexing display
information, including, e.g., financial market information
and television program information signals, from different
sources and transmitting the multiplexed signals to the
decoder-receivers for selectively displaying different
combinations of financial market information and/or
television program information signals on different video
screens.
