Title: Method of using speech recognition to initiate a wireless application protocol (wap) session
Inventor: GRIFFIN SHAWN
IPC: H04L29/08
Filed: 2001-06-29
Abstract: A method of initiating a data session between a wireless device and an information network over a wireless communication link includes establishing a voice session between the wireless device and a voice recognition application over the wireless communication link. A speech request is conveyed to the voice recognition application for information to be obtained from the information network. The voice recognition application converts the speech request into search criteria. A search of the information network is then initiated using the speech criteria and the voice session is terminated. A data session is then established with the wireless device and the search results are pushed to the wireless device over the wireless communications link.

Patent CA-2360484-A1 (CA)
Inventor: MICHAELIS PAUL R
IPC: H04M1/00
Filed: 2001-10-30
Abstract: A telecommunications switch (100) uses the speakerphone (104) of a user terminal (102) to announce display information, such as caller ID and other information. For example, in response to an incoming call, the switch checks (202) translations (123) to determine if announcing of display information is activated for the destination. If not, the switch displays (204) the caller ID on the display (103) of the destination terminal; if so, the switch activates (206) the destination terminal's speakerphone, converts (208) the caller ID to speech, and plays out (210) the caller ID through the speakerphone. Upon receipt (212) of a signal (e.g., off-hook) from the terminal, the switch ceases playing (214) out the caller ID, deactivates (216) the speakerphone, and (depending on the signal) connects (218) the call to the terminal. To effect a public announcement, the switch may activate a plurality of speakerphones and announce the same information through them simultaneously.

Title: Bovine viral diarrhea virus (bvdv) p80 and p80.delta.50 proteins as inducers of cell apoptosis in vitro
IPC: A61K38/00
Filed: 2002-05-27
Abstract: Bovine viral diarrhea virus (BVDV), which belongs to the Pestivirus genus of the Flaviviridae family, is one of the most important pathogen in cattle. BVDV  strains exist as two biotypes, cytopathogenic (cp) and noncytopathogenic (ncp), according to their effects on tissue culture cells. It has been previously reported that cell death associated to cp BVDV in vitro is mediated by apoptosis. In contrast to the situations described for other members of the Flaviviridae family (for instance, classical swine fever virus), only cp strains of BVDV express the p80 (also designated NS3 according to internationnaly recognized nomenclature) protein in virus-infected cells in vitro, suggesting its role in the cytophatogenicity of the virus. In order to determine whether the BVDV p80 is a key-factor invoved in the induction of cell apoptosis, the p80- and p80.DELTA.50 (which is the p80 deleted from the NH2-terminal 50 amico acids)-cDNA encoding sequences of BVDV NADL, cp strain were cloned into AdTR5-DC-GFPq transfer vector for the generation of recombinant adenoviruses (rec-adenovirus) from which the BVDV gene of interest could be expressed from a tetracycline-responsive promoter in a dicistronic means coexpressing the green fluorescent protein (GFP). A549 (human lung carcinoma cells) tTA (A549tTA) infected in vitro with p80 or p80.DELTA.50-expressing rec-adenoviruses showed cytopathogenic changes (e.g cell rounding and detachment, and nucleus chromatin condensation) beginning as early as 18 to 24 h post infection (pi) with the p80 or p80.DELTA.50-expressing rec-Adenovirus. DNA fragmentation assays (oligonucleosomal DNA ladder formation on agarose gel and TUNEL assay) performed on these infected cells clearly correlated the observed cytopathogenic changes with apoptosis. Moreover, we were able to correlate the BVDV p80 or 80.DELTA.50-induced apoptosis process with the activation of cellular proteases of the ICE family (caspases), as determined by cleavage of the death substrate poly(ADP-ribose) polymerase (PARP). This result suggests that the BVDV p80 or p80.DELTA.50 induced apoptosis through the caspase activation pathway. Together with the flow cytometry results on the DNA content of infected cells to quantitate apoptotic cells, the results of our study have shown, for the first time ever, that the p80 of BVDV is an inducer of cell apoptosis in vitro, and should be a determinant factor in the cytophatogenicity of cp BVDV in vivo. Moreover, the results have also shown that the 50 amino acids located at the NH2-terminal of the protein are not involved in BVDV p80-induced apoptosis, thereby identifying the BVDV p80.DELTA.50 as also a potent inducer of apoptosis.

Abstract: A wavelength division multiplexed (WDM) optical communication system which includes a detection device for preventing lasing in a physically closed optical loop. The detection device is included on each pass-through interface of each node in the WDM system. Each pass-through interface is assigned to a channel for a subset of the facility signal. The detection device includes a normally open switch is closed only when a real optical signal of the subset of the facility signal is detected, with the subset of the facility signal then being passed by the closed switch. Accordingly, when the switch is open, noise is blocked from initiating a lasing condition in a physically closed optical loop which disrupts customer service on the other channels.
