Patent EP-0818905-A3 (EP)
Inventor: MCKAY DANNY NEIL
IPC: H04L12/56
Filed: 1997-06-25
Abstract: A communication network and method improves the performance
(measured e.g. in terms of throughput) of a RTS/CTS based distributed
media access control protocol. The medium reservation is done in a
hierarchical fashion where first the shared medium is reserved for two
stations called the participants. All other stations called observers
stay quiet during the time reserved for the participants. In this
fashion, a shared medium can be reserved for a subset of the plurality of
devices. During this period called the reserved period, a master (or
primary), and a slave (or secondary) station attribute can be given to
the participating devices and the medium can be shared using another
medium coordination algorithm which is not necessarily the same as the
one used to reserve the medium for a reserved period in the first place.
After the medium is reserved, the participating devices can establish a
conventional point-to-point connection within the reserved time period
between participating devices for a predefined period of time. 
Specifically, the primary attribute can be exchanges with a secondary
attribute which in effect gives the control of the shared medium during
the reserved period to another station different from the one that
originally was assigned the primary attribute. During the reserved time,
the secondary can signal the primary station that it has data to send to
the primary station and request that the primary and secondary roles or
attributes to be exchanged. In the case that a role exchange takes place,
the control of the medium is transferred from one station to another and
data transfer in an opposite direction can take place without requiring
another reservation attempt.

Abstract: Elevator cabs A-C move upwardly through three or
more contiguous overlapping hoistways 38-40 in the upper
decks of double deck car frames 41-43, and move
downwardly through the hoistways in the lower decks (or
vice versa). To switch between decks, the cabs are
offloaded from the hoistways into auxiliary elevators
50, 51 at the terminal ends of the shuttle, and are
moved to be adjacent to the other deck by the auxiliary
elevator and loaded thereon for the trip in the opposite
direction. A second embodiment has additional auxiliary
elevators 64, 65 and additional cabs D, E so that
loading and unloading of passengers do not delay
movement of the cabs in the hoistways.

Abstract: An improved fastener is provided for use in retaining
vertebrae in a desired spatial relationship. The fastener
has a mounting section with a first external thread to
engage a vertebra. The fastener has a retaining section
with a second external thread to engage an internal thread
on a retaining element, such as a nut. A pair of parallel
flats are formed on opposite sides of the retaining
section. The flats are spaced apart by a distance which is
substantially the same as or greater than a root diameter
of the external thread on the retaining section. A driving
recess in an axially outer end of the retaining section has
arcuate corner portions which receive force to effect
rotation of the fastener relative to a vertebra engaged by
the mounting section. The arcuate corner portions of the
driving recess are offset from a plane containing the
longitudinal central axis of the retaining section and

Abstract: A video monitoring system for a movie film camera usable with either spherical or anamorphic lenses wherein conventional, unmodified video monitors and recorders may be used. A video camera is positioned in the film camera to receive an image directly from the camera lens without interposing either a ground glass for imaging or an optical deanamorphosing lens. The anamorphic image, which is horizontally squeezed (such as by a factor of 2), that is received by the video camera then is electronically processed to deanamorphose the image by producing an analog video signal to a video monitor that displays the properly proportioned image in the middle one-half of the monitor screen and produces black areas or strips across the top one quarter and bottom one quarter of the screen. The horizontal lines of the video picture are electronically interpolated for enhancing the picture. <IMAGE>

Abstract: An apparatus that gives continuous hydrogen heat treatment to
anisotropic rare earth magnet powders is invented. The apparatus a
comprises shopper 12, a furnace 11 to carry out a hydrogen heat
treatment, a heat compensating means 14 that is placed in the heating
room of the furnace to keep the treatment temperature constant, a
movable stopper 15 to support the material in the heating room of the
furnace 11 and a cooling container 18. The raw magnet powder is fed
into the furnace 11 and supported by the stopper 15, then hydrogen
heat treatment is carried out. After the treatment the stopper opens
the bottom end of the heating room and the processed magnet powder
falls into the cooling room. By the operation descried above, the
present apparatus can carry out continuous hydrogen heat treatment
without stopping the heating of the furnace batch by batch.
Continuous hydrogen heat treatment greatly improves the production
efficiency and quality of the processed magnet powder.

Abstract: An input image is divided into relatively small blocks of pixels. Border data
defining the areas are periodically calculated. For each pixel, a pair of selection pulses
indicative of the area where the pixel is located is generated. In response to the pair of
pulses, the gray scale characteristic is calculated for each area. The gray scale of the input
image is corrected using one of the gray scale characteristic associated with each area to
providing a corrected image signal for the area. In response to the pair of pulses, the
corrected image signals are combined into an output image signal. An optimal gray scale
correction is made for each area. The selection pulses are configured to gradually change
near the borders thereby making the reproduced image natural.

Abstract: Temporary states are used transitionally in run-time situations and are
unknown to the object database. A temporary state is created if, when an object is
performing a requested event, interim work needs to be performed before the object
reaches a permanent destination state. Use of a temporary state is transparent to the
caller of the requested event. Within a single flow of control, an unlimited number of
nested locks may be acquired. A request to unlock an object will only truly unlock
the object if the unlock requester is at the highest level of locking. For recursive or
embedded functions, no knowledge of the previous locking condition is necessary.
Attribute-based locking provides a mechanism for allowing only certain members of
the system to lock an object for writing while the object is in a predetermined state.
However, any thread may obtain a read lock on an object in order to examine its
attributes. This may be expanded to state that the system may restrict locking of an
object or entity based upon any attribute in the database or upon any combination or
logical expression of these attributes.

Abstract: An optical pickup is compatible with at least two
types of optical recording media using light beams having
respectively different wavelengths for recording and
reproduction of information. In the optical pickup, a
first laser light source (31) emits a light beam having a
relatively shorter wavelength. A first photodetector (34)
detects a reflected light beam with respect to the
relatively shorter wavelength. An objective lens (38)
forms an annular shielding region between a near axis
region of a relatively smaller radius and a far axis
region of a relatively larger radius. A laser unit (44)
emits a light beam having a relatively longer wavelength,
and detects only a light beam passing though the near axis
region in the objective lens (38) among reflected light
beams having the relatively longer wavelength. A
plurality of beam splitters (32, 35, 42) directs the light
beam emitted from the first laser light source (31) and
the laser unit (44) to the objective lens (38), and
directs the light beam reflected from each of the optical
recording media to a corresponding one of the first
photodetector (34) and the laser unit (44). The optical
pickup of the present invention has compatibility with
respect to disks regardless of the thicknesses and
various aspects of the disks, and can detect a good
signal. Also, optical pickups according to the present
invention can be manufactured and mass-produced at a low
