Title: Method and system for automatic activation of a wireless device
Inventor: LIPSIT JAMES MASON
IPC: G06F21/00
Filed: 1997-07-03
Granted: 2001-06-12
Abstract: Methods and apparatus for automatic activation of a wireless device in a subscription activation system are provided which use information received from a programmed but non-activated device. In one variation, the subscription activation system determines that the received information satisfies a parameter necessary for activation. In another variation, the subscription activation system verifies that the information received satisfies a previously determined criterion necessary for activation. Based upon the above, the subscription activation system activates the device. In a related manner, a system is constructed which uses an activation unit configured to receive and process information from a programmed non-activated wireless device. Using the information, the activation unit determines if activation criteria necessary for activation of the programmed wireless device in the system are satisfied and, based upon the information and if the criteria are satisfied, the activation unit activates the wireless device in the system.

Title: High pressure discharge bulb
Inventor: GOELLING HANS-WERNER
IPC: H01J61/82
Filed: 1997-08-14
Granted: 2004-10-19
Abstract: The invention concerns a high pressure discharge bulb.      Such bulbs involve a two-sided sealed bulb with and without an outer bulb. The bulb is sealed by a pinch on at least one side. It generally has a discharge vessel made of quartz. These bulbs particularly comprise metal halide bulbs, which have a metal halide filling in addition to mercury, but they also include mercury high pressure discharge bulbs or xenon high pressure discharge bulbs. The bulbs are used preferably for optical systems, particularly for photo-optical purposes, for example, in headlights, overhead projectors, and decorative lighting devices.      They particularly find application in lighting systems for the stage, film and television. Typical lamp powers are 400 to 2000 W. A discharge lamp pinched on both sides has pinches (4) in which the ratio of the total width of each wide side is smaller than or equal to 2.2 times the thickness of the wide side. Tube pieces (13) carrying the base sleeves (15) are shaped on the outer ends of the pinches. Fig. 2

Inventor: MA JINGJING
IPC: C08F297/04
Filed: 1996-01-16
Granted: 2008-10-07
Abstract: The present invention provides a block copolymer pressure sensitive adhesive (PSA) composition. The block copolymer has at least one midblock segment and at least one endblock segment. The midblock comprises a polymerized conjugated diene segment or hydrogenated derivative thereof. The endblock comprises a polymerized monovinyl aromatic segment having a number average molecular weight less than about 8,000. The PSA further comprises at least one tackifier or oil that is compatible with the low molecular weight endblock segment of the block copolymer. The PSA composition of the invention has a reduced elastic index and is capable of dissipating stress. This is useful in providing tapes which are capable of withstanding stresses such as those caused by temperature fluctuations, dimensional changes in the backing, or the recovery forces of a backing applied under tension. The present invention also provides a method of reducing the elastic index of a block copolymer PSA composition.

Abstract: AAL2 mini packets are integrated directly onto the physical layer to provide serial data transmission using statistical multiplexing.  This can be achieved by generating a plurality of frames of a predetermined size.  A plurality of AAL2 variable length mini packets are then statistically multiplexed onto the plurality of frames.  A pointer field is then inserted into each of the frames.  The pointer field includes a pointer that delineates the starting place of the next full packet in the frame that includes the pointer field, a framing bit that forms a pattern with other framing bits, and a parity bit.  The frames are then transmitted over a serial transmission line.
Patent CA-2240737-C (CA)

IPC: C12N15/09
Filed: 1996-12-20
Granted: 2009-09-29
Abstract: One aspect of the invention relates to the identification of the molecular basis of long QT syndrome. More specifically, the invention has identified that mutated KVLQT1 causes long QT syndrome. The analysis of this gene will provide an early diagnosis of subjects with long QT syndrome. The diagnostic methods comprise analyzing the nucleic acid sequence of the KVLQT1 gene of an individual to be tested and comparing them with the nucleic acid sequence of the native, non-variant gene. Alternatively, the amino acid sequence of KVLQT1 may be analyzed for mutations which cause long QT syndrome. Presymptomatic diagnosis of long QT syndrome will enable practitioners to treat this disorder using existing medical therapy. A second aspect of the invention relates to the realization that KVLQT1 coassembles with minK to form a cardiac potassium channel. This allows one to assay for drugs which interact with this channel to identify new drugs which are useful for treating or preventing long QT.

Abstract: Reduced performance of a fuel cell formed of a plurality of stacked unit cells caused by unequal gas flow rates in the unit cells is avoided through the use of separators, each having a plurality of through holes extending therethrough and a recessed portion formed in a surface of each separator. In a fuel cell incorporating such separators, the recessed portion of each separator forms an in-cell oxidative gas passage, together with an adjacent cathode. An oxidative gas, supplied from an external device into the fuel cell, is distributed from an oxidative gas supply manifold formed by holes of the separators, to the in-cell oxidative gas passages. The oxidative gas is then collected in an oxidative gas discharge manifold formed by holes of the separators, and conveyed out of the fuel cell by the discharge manifold.      During the passage through each in-cell oxidative gas passage, the oxidative gas flows via an oxidative gas transit manifold formed by holes of the separators.
