Title: Apex loudspeaker
IPC: H04R1/26
Filed: 1989-09-12
Abstract: A loudspeaker (10) has speaker mounting walls 
(11 and 12) joined at an apex angle (15) of 70° or less, 
with a pair of tweeters (20) mounted as close to the apex 
as possible and a pair of woofers (25), arranged below the 
tweeters, and also mounted as close to the apex as 
possible. The width spanned by tweeter pair (20), from a 
viewpoint in front of apex (15), is approximately equal to 
the frontal width of either tweeter. Similarly, the width 
spanned by woofer pair (25), from a viewpoint in front of 
apex (15), is approximately equal to the frontal width of 
either woofer. The geometry of this mounting arrangement 
produces even acoustic intensity throughout a wide angle 
around both sides of the apex and preserves stereo 
identity by having the sound emanate from an apparently 
small source.

Title: General network modeling and synthesis
IPC: H03H17/00
Filed: 1989-01-12
Abstract: A method and apparatus for modeling and synthesizing the 
response of a network to selected input signals where the input 
signals may be multi-channel in analog or digital form, and 
where the network's response may be linear or non-linear and 
depend on the present input signals as well as its past 
responses. A relationship is established between the input 
signals and the network's response to the input signals. Basis 
vectors are selected capable of representing the relationship. 
Weighting values for each basis vector are calculated. The 
calculated weighting values are applied to the corresponding 
basis vectors to form weighted basis vectors. The synthesis 
and modeling are then performed by forming a linear combination 
of the weighted basis vectors. Provision is made for feeding 
back the linear combination to account for memory and other 
history-dependent responses of the network.

Patent EP-0356085-A3 (EP)
Title: Automatic gain control fiber optic-to-electrical transceiver
IPC: H04B10/07
Filed: 1989-08-11
Abstract: A light source (140) is responsive to an input 
electrical signal (172) to increase or decrease its 
output depending upon whether the input electrical 
signal (172) corresponds to a higher light output level 
than the source (140) is currently providing or a lower 
light output level than the source (140) is currently 
providing, respectively. The output control comprises a 
light detector (146) for monitoring the light output and 
for producing a signal related thereto, a voltage source 
(156, 157) for establishing a maximum desired light 
output, a voltage source (158, 159) for establishing a 
minimum desired light output, and a window comparator 
(152, 154) for comparing the detected signal to the 
maximum and minimum desired light outputs. The light 
detector (146) and voltage sources (156, 157, 158, 159) 
are coupled to the window comparator (152, 154). A 
binary counter (162) selectively generates a periodic 
signal. An OR gate (160) couples the window comparator 
(152, 154) to the binary counter (162). A D/A converter 
(170) and light source driver (172) couple the binary 
counter (162) to the light source (140). The binary 
counter (162) provides the periodic signal as the input 
electrical signal to the light source (140) in response 
to the window comparator (152, 154) determining that the 
light detector (146) signal is not related to a light 
output between the maximum desired light output and the 
minimum desired light output.

Title: Multilayer flexible marking tape
IPC: C09J7/29
Filed: 1990-07-14
Abstract: There is described a multilayered, flexible marking tape comprising an auxiliary support and a contact-adhesive layer. Between the auxiliary support and the contact-adhesive layer there is situated a binder-containing cover layer which is more adherent to the contact-adhesive layer than to the auxiliary support. The contact-adhesive layer has been coloured with a colorant, in particular a pigment. If fluorescent pigments are incorporated into the contact-adhesive layer, the marking tape becomes highly suitable for marking or highlighting passages in written text. A suitable choice of contact adhesive permits later easy removal without impairment of the marked sheet.

Title: Frame relay system capable of handling both voice and data frames
Inventor: BERGMAN WILLIAM CARL
IPC: H04L12/56
Filed: 1993-06-30
Abstract: Modifications to existing frame relay communication
protocols are described which permit both voice and data
packets to be handled in an integrated frame relay system.
A Voice Frame Identifier bit is defined in the address
field of a frame. When an intermediate node detects a
voice packet, a CRC operation is performed using only the
frame header; that is, voice information is excluded from
the computation. The frame is flagged for priority processing
in the node. When the intermediate node detects a
data packet, the CRC operation uses both the header and
the data fields.

Abstract: An improved access control apparatus, method, and system are
disclosed to enhance the security of information in cards of
the type having data storage and functions which are not
accessible without verification of the identity and the
authority of a person requesting access. The card need not
include identification information for others that may require
access to information in a person's card. Several
authorization profiles are provided in a card, but there is no
need that a profile be identified to any one person in order
that they each may perform required tasks using or adding
information in another person's card. The identification card
of a supervisor or doctor who requires access to another
person's card contains secret information Xsup identifying the
supervisor or doctor as having the authority of supervisor or
physician and an encryption key. The secret authorization
information is encrypted and transmitted through the reader to
the other person's card where it is decrypted and compared with
the X'sup secret value stored in the other person's card. If
they agree, the supervisor is permitted to perform functions
authorized to be performed by supervisors in accordance with
the profile for supervisors in the other person's card. Each
supervisor is identified by a supervisor's own card using a
password, PIN, or biometrics that may be changed as often as
desired without recalling the cards of others for update. The
authorization information is not exposed outside of a secure
environment. Therefore, unlike PINs which are exposed during
entry, it need not be changed or updated during the life of the
card.

Abstract: Parallel laser beams #1, #2 and #3 produced by
splitting one laser beam into three, are introduced to an
optical scanning device (2) along the central axis of a
recording cylinder (24), the optical scanning device being
disposed on the central axis of the recording cylinder and
rotated thereabout, having an inclined mirror surface (4),
the recording cylinder holding a recording sheet (S) on an
interior surface thereof. The laser beam #2 incident upon
the mirror surface at its center of rotation is reflected at
the point of incidence, while the laser beams #1 and #3 are
deflected by acousto-optical devices (10X, 14X) back and
forth in the opposite directions in synchronism with the
rotation of the optical scanning device, in parallel planes
held at a distance and including the laser beams #1 and #3
therein, thereby to give the laser beams #1 and #3 angles of
incidence upon the mirror surface necessary in order for the
laser beams #1, #2 and #3 after reflected to produce scanned
loci running parallel to each other at a given interval on
the recording sheet, regardless of rotational positions of
the optical scanning device. To adjust a relative difference
in the lengths of the scanned loci, timing at which the laser
beams #1, #2 and #3 are turned on/off is controlled. When the
laser beams #1 and #3 are deflected so as to gyrate along a
conical plane whose central axis is that of the recording
cylinder, the laser beams #1, #2 and #3 produce scanned loci
always running parallel to each other at a given interval
with the same scanning lengths on the recording sheet.
