Title: Pressurized sealable transportable containers for storing a semiconductor wafer in a protective gaseous environment
Inventor: GARRIC GEORGES
IPC: B65G49/07
Filed: 1993-04-20
Granted: 1998-04-21
Abstract: The  novel  pressurized  sealable  transportable  container basically includes a box-shaped cassette reservoir provided with a slot-shaped access opening normally tightly closed by releasable  door  means  typically  a  pivoting  cover  for hermetic sealing. The cassette reservoir interior space is filled with an adequate quantity of a pressurized ultra-pure neutral gas. This gas is supplied by a compressed gas supply installation through gas injection valve means, including a high efficiency filter and a non-return valve. The pressure which prevails in the cassette reservoir interior space has a  positive  differential  pressure  (about  5000  Pa)  with respect to the outside ambient to prevent any contamination thereof.  The cassette reservoir is preferably made of a transparent  and  non-contaminating  material  such  as  a plastic.  It  is  provided  with  a  bar  code  tag  so  that identification data attached to the wafer can be directly and  automatically  read  by  an  appropriate  reader.  The cassette reservoir includes a drilled inner wall provided with holes that demarcates two regions within said container interior space: a first region in relationship with said gas injection valve means to form the reservoir properly said and a second region or receptacle adapted to receive a wafer holder. The cassette reservoir includes means for firmly and accurately maintaining the holder therein. The holder has a slot-shaped transfer opening enclosing a single wafer and is adapted  to be inserted in and removed from  and from the said  receptacle  through the  said  access  opening  at  the beginning  and  at  the  end  of  the  wafer processing  step sequence.  The holder  is provided on  its  rear face with via-holes that are designed so that the gas flowing from the reservoir into the holder interior space, first through said holes,  next  through  said via-holes,  does  not  so  easily penetrate  in  the  holder  interior  space.  The  holder  is preferably  made  of  a  transparent  and  non-contaminating material  such as  a plastic  or pure  SiO2  (quartz).   The holder includes means for softly but firmly maintaining the wafer therein.

Title: Liver enriched transcription factor
Inventor: SLADEK FRANCES M
IPC: C07K16/00
Filed: 1991-12-23
Granted: 2002-11-26
Abstract: HNF-4 (hepatocyte nuclear factor 4) is a protein enriched in liver extracts that binds to sites required for the transcription of the transthyretin (TTR) and apolipoprotein CIII (apoCIII) genes (Costa et al., 1989; Costa et al., 1990; Leff et al., 1989). We have purified HNF-4 protein (54 kD) and isolated a cDNA clone encoding the protein. HNF-4 is a member of the steroid hor-mone receptor superfamily with an unusal amino acid in the conserved "knuckle"  of the first zinc finger (DGCKG). This and the fact that HNF-4 does not bind significantly to estrogen, thyroid hormone or glucocorticoid response elements indicate that HNF-4 may represent a new subfamily. HNF-4 binds to its recognition site as a dimer and activates transcription in a sequence-specific fashion in nonhepatic (HeLa) cells. HNF-4 mRNA is present in kidney and intestine as well as liver but is absent in other tissues. DNA binding data suggest that HNF-4 could be identical to liver Factor A (LF-Al), a factor previously shown to regulate the transcription of the .alpha.-1 antitrypsin, apolipoprotein Al and pyruvate kinase genes.

Title: Secure telecommunications
Inventor: KAPLAN MICHAEL M
IPC: H04Q3/00
Filed: 1994-06-29
Granted: 1998-09-22
Abstract: A security node disposed in the telecommunications network connecting calling and called parties transforms information (which can be voice, data, facsimile, video and other types of calls or messages) encrypted in a first format to (a) encrypted information in a different format or to (b) non-encrypted information, and vice-versa. The node is accessible from any location connected to the network. By routing calls or messages originated by the calling party and destined for the called party via the security node, and providing appropriate control signals to the node, the information may be encrypted only over a portion of the transmission path between the parties, and clear over the remainder of the transmission path. Alternatively, the information may be encrypted in different portions of the path using different encryption algorithms. This arrangement enables the parties to obtain relatively secure communications even if only one party has a security device at the originating or terminating end, or if the parties have security devices using different handshaking protocols and encryption algorithms.

Title: Method for enhancing detection ability of nucleic acid assays employing polymerase chain reaction
Inventor: BLAIS BURTON W
IPC: G01N33/53
Filed: 1994-12-23
Granted: 2010-03-30
Abstract: This invention relates to a new and novel method for significantly enhancing the sensitivity of assays aimed at detecting the presence of target deoxyribonucleic acid (DNA) or ribonucleic acid (RNA) sequences in a sample. Specifically, this method applies to techniques that employ polymerase chain reactions (PCR®) or other nucleic amplificatio techniques to amplify copies of the target DNA or RNA (via reverse- transcriptase followed by PCR, Murakawa et al. 1988 DNA 7-287) to allow for detection. The method of the present invention combines the following four steps for the first time: DNA amplicon synthesis and amplification in a modified PCR using a target nucleic acid sequence as a template; amplicon transcription into RNA and amplification ; RNA:DNA hybrid formation; and immunochemical detection of heteroduplex nucleic acid sequences. This method extends the standard PCR techniques to accommodate amplification of copies of the PCR product and transcription into RNA, which, following binding to DNA sequences facilitates immunochemical detection of the RNA:DNA hybrids thereby formed. This combination of steps results in a new assay with increased simplicity, speed and sensitivity, including a greatly improved signal-to-noise ratio, over standard nucleic acid detection methods. This improved method will be extremely useful for performing analyses in the forensic, clinical, agricultural and biological fields.

Filed: 1995-08-11
Granted: 2000-03-21
Abstract: A sales promotion program is dynamically selected from a plurality of programs for presentation in a program presentation unit by a neural network that makes its selection based on first detecting if a person is in the area immediately around the program presentation unit, then either selecting a general attract loop sales promotion program with the trained neural network using a set of predetermined system criteria if no person is detected in the immediate area or selecting a specific loop sales promotion program if at least one person is detected in the immediate area. The neural network is trained by selecting general attract loop programs that are run and then collecting data indicative of the number of persons responding to the general attract loop and also by selecting specific loop programs that are run if a person is in the immediate area and then collecting data indicative of the responses to the specific loop programs. The collected data thereby represents the success of the various sales programs in attracting and holding the attention of persons. The collected data is provided to the neural network in any one of a plurality of training schemes typical for neural networks, after which the trained neural network is provided with current, real-time selection data such that the trained network can select the most appropriate sales promotion program for running. The network canbe retrained at regular intervals or in response to sales data or changes in thecollected data.

Title: Multichannel apparatus for epidural spinal cord stimulation
Inventor: HOLSHEIMER JAN
IPC: A61N1/34
Filed: 1995-01-23
Granted: 2001-12-18
Abstract: Apparatus for multi-channel trans-verse epidural spinal cord stimulation uses a multi-channel pulse generator driving a plurality of electrodes mounted near the distal end of a lead. These electrodes are mounted in one or more lines gen-erally perpendicular to the lead axis, and have a planar surface along one surface of the lead. The lead is implanted ad-jacent to spinal cord dura mater with the electrodes transverse and facing the spinal cord. Pulses generated by the pulse gener-ator for each channel are normally simul-taneous, of equal amplitude and of equal duration however, the pulse generator is arranged such that pulses for each channel ran selectably alternate in time can se-lectably be of unequal amplitude, or both. The changes in pulse timing and magni-tude permit shifting the electrical stimu-lation field and the resulting paresthesia pattern after installation to accommodate improper lead placement or postoperative dislocation and to minimize unwanted mo-tor responses.
