Abstract: A system for controlling fuel metering for a multi-cylinder internal combustion engine having a feedback loop which has an adaptive controller and an adaptation mechanism coupled to said adaptive controller for estimating controller parameters θ̂. The adaptive controller calculates a feedback correction coefficient using internal variables that include the controller parameters θ̂, to correct a basic quantity of fuel injection to bring a detected air/fuel ratio to a desired air/fuel ratio determined earlier from the detected air/fuel ratio by a dead time d'. The dead time d' is properly determined (S20) to be corresponding to a time k at which the air/fuel ratio is detected. Alternatively, the dead time may be determined to be longer than the proper value to eventually improve vehicle drivability, or determined shorter than the proper value to compensate for a insufficient fuel adhesion correction.

Abstract: The invention relates to the formation of a wide-band data transfer link (WB) as an extension to a data transfer system, which comprises narrow frequency bands (f2) for the organization of narrow-band data transfer calls using one frequency band. In accordance with the invention the data stream (S) which is to be trans-mitted is divided into substreams (S5 - S9), each of which modulates a different frequency band (f5 - f9). The signals thus obtained are combined (C) for trans-mission. The received signal is divided into frequency bands, which are de-modulated separately, and from the data substreams thus obtained the original data stream is reconstructed. The wide-band communication in accordance with the invention (WB) may further be divided among many users on the principle of time or frequency-division multiple access.

Abstract: A luminometer for determining the composition of a specimen sample includes an annular guide path for sample containing cuvettes within a light tight housing. A rotor moves spaced segments through the guide path with the cuvettes positioned between the segments. The luminometer further includes one or two detector assemblies (110,112) coupled to the housing and positioned to view and detect light emitted by cuvettes as they pass along the guide path between segments. A cuvette is advanced around the housing via the rotor and rotor segments and when the cuvette reaches a predetermined position on the housing, a reagent, such as a base, is added to the cuvette to initiate a chemiluminescent reaction within the cuvette and provide an emission of light energy in a predetermined spectral range. The luminometer has a waste aspiration probe to remove the contents of the cuvette after it passes the detector. A cuvette elevator moves a sample containing cuvette into the guide path between segments and an exit chute removes cuvettes after their contents have been aspirated. The luminometer permits continuous uninterrupted sample testing when coupled to an incubation chamber in which the cuvettes receive samples and test specific reagents before they are moved into the luminometer by the elevator. 
     The luminometer has a temperature detection and control circuit coupled to the detector (PMT) (110) with thermal insulating sleeve (126). A TED (132) is coupled to the PMT thermal sleeve. The PMT comprises a lens cap (128) and a seal.

The switch fabric provides all voice channel connections between all switches and the remote terminal and grooms the control channels. Control messages are switched into the command module, which performs any protocol translations necessary. All commands from switches are then multiplexed and sent back to the switch fabric, which routes them to the original command channel to the remote terminal. Control messages from the remote terminal are demultiplexed, translated (if necessary) and sent to the switch fabric for delivery to the appropriate switch. Testing of lines is also provided to all competitive service providers.

Abstract: A method and apparatus for detection of missing pulses (22-28) from a repetitive pulse train (20) including signal detection circuits for capturing the rising and/or falling edges of an input signal (60), time-stamping the captured edges, calculating the maximum and minimum instantaneous frequency over a specified time period, and displaying such frequency values (31, 32, 33, 35, 37, 39). Instantaneous frequency values between any two adjacent edges are calculated based upon the time-stamps of the edges. The instantaneous frequency values in a specified time period are then sorted to find the minimum (32, 35, 39) and maximum (31, 33, 37) frequency values for that time period. These instantaneous frequency values are displayed in the form of a histogram (29) evidencing the occurrence or lack of occurrence of missing pulses (22-28) from the input signal (60).

Abstract: An automatic beam current limiting apparatus is provided for limiting beam currents of R, G, and B colors separately without disturbing the increase of an amplitude and a frequency range for CRT driving. In particular, the APL of each of R, G, and B color video signals at the preceding stage of a video power amplifier is detected and compared with a reference voltage. When the APL of the video signal is higher than the reference voltage, the video signal is controlled in the amplitude to limit the beam current for driving the CRT. Also, the comparison of a result calculated by a calculating circuit from APL, G1 voltage, and G2 voltage may be made with a reference voltage. When the result is higher than the reference voltage, the amplitude of the video signal is controlled to limit the beam current for CRT driving.

Abstract: DVD reproducing apparatus (902) which transmits variable-bit
rate data on a digital serial bus (901) having a predetermined
transmission rate. The DVD reproducing apparatus reproduces data
from a record medium (1) in accordance with a control signal to
produce variable rate data. The peak data rate of the variable
rate data is detected (8), a rate of transmission of the variable
rate data is established in accordance with the detected peak
data rate, and the variable rate data is transmitted in
accordance with the established transmission rate. The DVD
reproducing apparatus includes an MPEG decoder (6) which MPEG decodes
the reproduced data and which generates the control signal in
accordance with amounts of data stored within various buffers (64,65),
such control signal being utilized to control the reproduction of
the data from the record medium. A receiver (220,500), e.g., a digital
television (200), having an MPEG decoder (9) therein receives the
transmitted data and MPEG decodes the data, but such MPEG decoder
does not generate a control signal similar to the previously
generated control signal in order to prevent underflow/overflow
of the memories therein. In another embodiment, the DVD
reproducing apparatus does not include therein an MPEG decoder,
but the receiving device's MPEG decoder, unlike the first
mentioned embodiment, generates a control signal that is 
transmitted back to the DVD reproducing apparatus in order to
prevent underflow/overflow of the memories within the receiving
device's MPEG decoder.
