Title: Echo canceller
IPC: H04B3/23
Filed: 1990-04-05
Abstract: An echo canceller modem having a fast training echo canceller is described. The echo cancellation coefficients are computed by taking correlations between a complex, periodic training signal sequence and a real component of the corresponding echo signal. The modem includes a receiver circuit which detects a signal on a channel possibly including an echo. An echo canceller estimates the real component of the echo signal. Training circuitry applies the complex training sequence to the channel and takes correlations between the training sequence and the real component of the corresponding echo signal. In the preferred arrangement, the modem also includes a computational element for computing the period of the periodic sequence, generating the complex periodic training sequence in real time and for computing a phase roll frequency based upon the computed echo cancellation coefficients.

Title: Method and apparatus for machining circuit boards, in particular circuit boards with surface-mounted components
IPC: B23K31/02
Filed: 1991-11-04
Abstract: During the pickling process in the novel method of soldering electronic printed circuit boards, in particular component-carrying printed circuit boards, a condensable auxiliary substance, for example water, is first adsorbed in defects in the oxide layers on the solder connection pads and at least partly condensed in the defects. The oxide layers are then subjected to such fast heating that the auxiliary substance condensed in the defects explosively evaporates and consequently breaks up the oxide layer, which detaches itself from the metallic base material in such a way that the solder connection pads are converted to a virgin state for the subsequent soldering process itself. In the case of wave soldering, the fast heating is preferably carried out by the solder wave itself. If nonoxidic passive layers have also to be removed by pickling, this is preferably done in a preceding step in the pickling process, during which the oxide layer is rendered hydrophilic. A plasma pretreatment is suitable for this purpose. The novel apparatus has a moistening chamber in which the condensable auxiliary substance is presented to the hydrophilic oxide layers and is adsorbed by the latter.

Inventor: LIN THOMAS
IPC: B26D3/18
Filed: 1991-04-24
Abstract: A cutting device for cutting an objection such as a citrus fruit includes a cutting assembly and an outer casing about the cutting assembly. The casing is generally cylindrical having a central axis, and has open ends. The cutting blade assembly includes a first cutting blade extending radially outward from the central axis to a sidewall of the casing, the first cutting blade cutting the fruit in a manner so as to completely sever one portion thereof from another.

Abstract: A transmission power control circuit for controlling
a power level of a transmission signal is provided which
comprises a variable attenuator (2) for adjusting the
amplitude level of an input signal, a detection circuit
for detecting an amplitude of the transmission signal via
a branch circuit (5), a reference voltage source (7) for
generating a reference voltage associated to a predetermined
level of the transmission signal to be transmitted, a
comparator (11) for comparing the reference and detection
voltages, a clock generator (13), an up/down counter (12)
for up or down counting pluses of a clock output from the
clock generator, a D/A converter (14) for converting the
count value of the counter, and a control circuit (10). The
comparator subjects the counter to the up or down counting
operation when the detection voltage is less or larger than
the reference voltage to provide an attenuation control
signal to the attenuator through the D/A convertor so that
attenuation level is adjusted, whereby the detection voltage
substantially coincides with the reference voltage. The
control circuit controls the reference voltage source to
vary the level of said reference voltage in accordance with
the transmission signal and controls the clock generator
to generate the clock having a high frequency during
a transition period of the reference voltage and a low
frequency during the reference voltage being kept
substantially constant, whereby change of the transmission
power level can be executed at a relatively high speed
without interference for the adjacent channels.
