Title: Method for purification of ibuprofen comprising mixtures
IPC: C07C51/43
Filed: 1991-09-06
Abstract: This invention pertains to a method of purifying ibuprofen-comprising reaction product mixtures. The method of purification is based on crystallization of ibuprofen from a hydrocarbon solvent and the discovery that there are impurity complexes in the ibuprofen-comprising reaction product mixtures which cannot be removed by crystallization from a hydrocarbon solvent. The method of the invention includes at least one step in which the impurity complex in a first ibuprofen-comprising mixture is destabilized or broken up, followed by crystallization of the ibuprofen from a second solution or mixture comprising the first ibuprofen-comprising mixture, whereby the impurities which were previously complexed can then be removed from the ibuprofen by the crystallization of ibuprofen from a solvent. <IMAGE>

Title: Method and device for acoustic echo adaptive cancellation
IPC: H04M9/08
Filed: 1992-08-26
Abstract: Applicable to adaptive filtering of broadband acoustic signals, the objective being to eliminate problems of acoustic echoes. The method includes an additional stage for the generation of an inhibition vector (22) associated with the different segments of the filter that is fed with information from the activity monitoring stage (19) of the transmission and reception lines. The generation of the inhibition vector (22) takes into account the presence or lack of double-talking, implementing an adaption strategy that establishes the sections of the filter to be updated in each iteration. The calculation of the adaption step, independent for each uninhibited filter segment in the iteration in process, takes into account the local spectral characteristics of the voice signal and includes a new computational strategy. The device implements the different phases and stages of the method. The invention presents the advantages to increase the rate of convergence of the algorithm regardless of the incoming signal spectral characteristics, to improve the performance of the echo canceller, and to use a single digital signal processor. <IMAGE>

Abstract: A data copyright management system comprises a database for storing
original data, a key control center for managing crypt keys, copyright
management center for managing data copyrights, and a communication network for
connecting these sections each other; data supplied from the database to users
is encrypted and distributed, and the users decrypting the encrypted data by
crypt keys obtained from the key control center or copyright management center
to use the data. 
     To supply data to users, there are the following two methods: one for one-way
supplying encrypted data to users by means of broadcasting or the like, and
the other for two-way supplying encrypted data to users corresponding to users'
requests. 
     A crypt key system used for encrypting data uses a secret-key cryptosystem,
a public-key cryptosystem or a cryptosystem combining a secret-key and a public-key
and moreover, uses a copyright management program for managing data
copyrights. 
     When a user stores, copies, or transfers data, the data is encrypted by a
crypt key different from a crypt key used for supplying the data. The former
crypt key is supplied from the key control center or from the copyright
management center, or generated by the copyright management program. 
     Moreover, the present invention can be applied to a data copyright
management system for using not only signal data but also a plurality of data
supplied from a single database or a plurality of data supplied from a plurality
of databases. 
     Furthermore, an apparatus to be used by the user to perform data copyright
management is also proposed.

Abstract: A microprocessor (1) controlling a shuttle shift transmission (10) may be programmed while the gearshift lever (6) is in neutral to preselect a forward and reverse gear into which the transmission (10) is shifted when the gearshift lever (6) is moved to a forward or reverse position. The microprocessor (1) may also be programmed so that, in shifting between forward and reverse, the forward and reverse gears selected differ by a preprogrammed amount. The microprocessor (1) may be programmed to control vehicle deceleration by selecting gears in the transmission (10) so that the transmission (10) and/or the vehicle engine (7) become a load for decelerating the vehicle. In a diagnostic mode, the microprocessor (10) executes a routine to develop a clutch calibration value which may later be used to insure uniformity of clutch operation in different vehicles, or in the same vehicle over a period of time. The normal speed ratio matching which normally takes place when shifting gears may be manually overridden by operator manipulation of the gearshift lever (6). The override may either terminate speed ratio matching for a particular shift, or the override may be effective for a fixed interval of time. <IMAGE>

Abstract: A photovoltaic device uses a spectrally selective photon partitioner
such as a reflector (14) to partition incoming light
(10) which is directed towards different solar cells (16, 18),
depending upon its energy. Solar cells (16, 18) having low and
high energy band gaps are used, in which low energy photons are
imaged towards that cell (18) having the lower energy band gap,
whereas high energy photons are imaged towards the higher
energy band gap cell (16). By more directly imaging photons
towards those cells (16, 18) in which they are converted to
electricity, absorption losses due to free carriers in the
semiconductor layers (30, 32, 36, 38) are reduced. The
spectrally selective photon partitioner (14) allows semiconductor
layers (30, 32, 36, 38) having different lattice spacings
to be optically coupled.

Abstract: A television viewer can easily navigate
programs which are grouped according to a common
service provider or other grouping criteria by
depressing the "channel up" or "channel down"
buttons on a hand-held remote control. Programming
services which are provided via one or more
transmission paths are integrated, thereby allowing
a viewer to successively select the grouped channels
regardless of the broadcast signal, transmission
path, frequency spectrum, transport stream and/or
PID in which the channel is carried. Data is
provided with broadcast signals to indicate
broadcast address information which corresponds to a
primary channel and one or more secondary channels
of a channel group. A viewer can successively view
the channels of the group while bypassing
intermediate non-group channels. Grouped channels
can thus be designated by a common channel
designator such as a channel number. Goodwill and
brand loyalty which has been built up over time in a
local station channel number can be used to define a
family of programs to maintain continuity as
channels are added or dropped, or channel
assignments of programming services are rearranged.
