Patent EP-0817183-A2 (EP)
Inventor: LEWIS DAVID EARL
IPC: G11B11/10
Filed: 1996-03-19
Abstract: An apparatus for controlling the strength of a magnetic field, comprises a
first controller (14), a second controller (15), a digital-to-analog converter (16), a
current driver (17), and a bias coil (18). The first controller (14) determines the
position of the focal point of a lens (29) and passes it to the second controller (15),
which provides a digital signal related to the position. The digital-to-analog converter
(16) converts the digital signal to a driver voltage and passes the driver voltage to a
current driver (17), which provides to the bias coil (18) a bias current related to the
driver voltage. The bias coil (18) produces a magnetic field having a strength related
to the bias current. The second controller (15) accounts for stray magnetic fields in
creating the digital signal. The stray magnetic fields may be constant or may vary in
strength based on position of the objective lens (29), circumferential velocity of the
storage medium (2, 4), or longitudinal velocity of the storage medium (2, 4).
Furthermore, the apparatus may comprise a current sensor (26) for measuring the
bias current, and a feedback device for providing to the current driver (17) a
feedback voltage related to the bias current.

The circuit has an OR gate (OR) with first and second inputs and an output. The circuit also has a clocked D-type flip-flop with a data input (D) connected to the output of the OR gate. It also has a non-inverting flip-flop output (Q) and a clock input (CLK). The circuit also has an exclusive OR gate (XOR). This has a first input to which a series of address words to be tested are fed with a predetermined clock frequency. The exclusive or gate (XOR) has a second input to which the filter bit stream are fed. The XOR gate has an output connected to the first input of the OR gate (OR). A clock signal corresponding to the clock frequency is fed to the clock input (CLK). At an end of the address word to be tested, acceptance is signalled by a logic value '0' at the flip-flop output (Q). Non-acceptance is signalled by a logic value '1'.

Abstract: A directionality enhancement system converts
encoded stereo signals on input channels A and B into
four signals on left, centre, right and surround
output channels. The input signals on the A and B
input channels are respectively attenuated as
functions of the difference of the logs of the signals
on the A and B input channels to produce first and
second attenuated signals. The sum and the difference
of the input signals on the A and B input channels are
respectively attenuated as functions of the difference
of the logs of the sum and difference of the signals
on the A and B input channels to produce third and
fourth attenuated signals. The signals on A and B
input channels and the sum and difference of them are
then combined together with the four attenuated
signals to produce left, centre, right and surround
outputs.

Abstract: An optical communication system and methods are disclosed wherein
the receiving source uses an array sensor to recover data from a transmitted optical
beam and to evaluate alignment accuracy with the transmitted beam. The array
sensor uses the principles of geometric invariance to determine the accuracy of
alignment. The sensor may relay the recovered information to a system controller or
other suitable device, which can then reposition the receiver so that it is properly
aligned with the transmitter. The system and methods advantageously provide for a
more compact and robust communication system wherein a single receiving element
can be used for both data recovery and alignment evaluation functions.

Abstract: Method for non-invasively determining glucose level in fluid of subject, typically blood glucose level. A particular device is mounted on the skin of the patient for a fixed period of time. The device is mounted on the skin such that a substrate such as paper or gel or an aqueous glucose solution carried by the device are in contact with the patient's skin. Water and/or glucose migrates between the substrate or the aqueous glucose solution of the device. The degree of migration of the substance in question is monitored, for example the amount of glucose remaining in an aqueous solution of the device is measured at the end of the fixed period. This can be done by a conventional or other spectrophotometric method, for example. The glucose level is determined based on the degree of migration of the migrating substance. That is, the degree of migration is correlated with previously determined fluid glucose levels based on directly measured fluid glucose levels. In another approach, impedance alone is measured at the skin surface over a relatively short time period, even less than one second and the impedance is correlated with previously determined glucose levels. It is thus possible, through such a correlation, to routinely non-invasively determine fluid glucose levels.

Abstract: A media selection device is in functional parallel
with an alternate local telephone network and an
existing local telephone network. Upon detecting a loss
of local power, the device switches to the local
exchange network based on the assumption that the local
exchange network is operable, despite the loss of local
power. While power is supplied to the device,
originating calls are transmitted from the telephone to
the device and to the alternate network. Incoming calls
from the alternate network are transmitted to the device
and to the telephone. Alternatively, incoming and
outgoing calls are also selectably engageable on the
local exchange network without disrupting telephone
service on the alternate network. Differences in dial
tone indicate which network is currently being used.

Abstract: Two duplex channels are provided using only three
lines, two power lines (208,212) and one neutral line (210). The
transmitter receiver (122,202) of each duplex channel includes adaptive
filters to cancel cross-coupling introduced by the common
neutral line. Each channel is coupled to a power line using
a hybrid line driver/receiver device. The hybrid line
driver/receiver device includes an echo canceller and a
bridge circuit to allow transmitting and receiving signals to
and from a single power line with minimized echoing effects.
The signal-to-noise ratios of each duplex channel is
significantly increased so that two duplex channels may be
implemented using only three wire connections. Thus, the
communication capacity of power line communication systems is
greatly increased compared to that for a single 2-wire
channel.
