Title: Resilient hinge for spectacles
IPC: G02C5/22
Filed: 1990-04-19
Abstract: The invention relates to a resilient hinge for spectacles for pressing the spectacle bow beyond the stop position, to be placed resiliently on the wearer's head. By contrast with the known embodiments, in this arrangement the assembly is to be performed with locking of the resilient hinge under spring pressure simply by pushing inwards in the longitudinal direction, without the need for additional anchoring parts or rotary movements for locking purposes. For this purpose, the locking member is constructed in the form of a U-bracket, which can be pushed in with the open U-end and has on the end side on one U-limb a catch nose which catches firmly upon being pushed in under spring action on a recess of the guide receptacle. <IMAGE>

Title: Circuitry for widening the effective range of a transmitter
IPC: H03G3/20
Filed: 1990-05-08
Abstract: The present invention concerns a circuitry for widening the 
power control range of radio telephone. A radio frequency 
signal is amplified in a controllable power amplifier (1). 
According to the invention, after the amplifier a controll­
able switch (4) is connected, which, while in a first state, 
does not substantially attenuate the RF power emitted trans­
mitted from the power amplifier (1). The first power control 
range of the transmitter is thus produced. When the switch 
(4) is in a second state, it directs part of the RF power 
transmitted from the power amplifier (1) to a resistive 
element (R1) and permits part of the RF power to be trans­
mitted to the output (RFout) of the transmitter. A second 
power control range is produced in this manner.

Title: Remote data duplexing.
Inventor: MICKA WILLIAM FRANK
IPC: G06F12/16
Filed: 1993-12-01
Abstract: A system for asynchronously duplexing direct access storage device (DASD) data in a plurality of DASD subsystems has the advantage of decoupling the data duplexing operation from the DASD write I/O operation. This ensures the write does not incur unnecessary wait states in the subsystem. By establishing a sequence checkpoint at which time a set of information packets are grouped together and processed as a single sequence unit, this decoupling and independent operation takes place. Through this independence, data copying to a secondary location can take place without affecting the performance of the subsystems and also not affecting the corresponding integrity of the data that is being updated. <IMAGE>

Abstract: A system and method for discovering consumer purchasing tendencies
includes a computer-implemented program which identifies consumer
transaction itemsets that are stored in a database and which appear in
the database a user-defined minimum number of times, referred to as
minimum support. The itemsets contain items that are characterized by a
hierarchical taxonomy. Then, the system discovers association rules,
potentially across different levels of the taxonomy, in the itemsets by
comparing the number of times each of the large itemsets appears in the
database to the number of times particular subsets of the itemset appear
in the database. When the relationship exceeds a predetermined minimum
confidence value, the system outputs a generalized association rule which
is representative of purchasing tendencies of consumers. The set of
generalized association rules can be pruned of uninteresting rules, i.e.,
association rules which do not occur at a frequency that is significantly
different than what is expected based upon the frequency of occurrence of
the rule's ancestors.

Abstract: A method and apparatus are provided for maintaining
synchronous return and forward communications links between user
terminals and earth stations communicating via a common satellite
in a satellite based telecommunications system. Each user terminal
maintains a closed synchronization loop with its associated earth
station based on timing and frequency error offset signals received
by the user terminals. The user terminals update their internal
timing and frequency generators based on the received error offset
signals. In an earth station sharing embodiment, one of the earth
stations is designated as a master earth station while the
remaining stations are designated as slave earth stations with
respect to a common satellite. The slave earth stations monitor a
return link between at least one user terminal and the master earth
station. The slave earth stations update their internal reference
timing and frequency signal generators, in order to remain
synchronous with the return link between the monitored user
terminal and the master earth station. The slave earth stations
maintained synchronous forward links by requesting synchronization
update information from the monitored user terminal. Upon
receiving a request, the monitored user terminal calculates a
difference in timing and frequency between frames received from the
requesting slave and associated master earth stations. The user
terminal transmits the difference in timing and frequency along its
return link. The slave earth station updates its forward link
timing and frequency reference signal generators to remain
synchronous with the master earth station.
