Abstract: This disclosure describes a method comprising: obtaining, by a processing system that includes one or more processors implemented in circuitry, a signal from a magnetic sensor of a hearing instrument; determining, by the processing system, a context of the hearing instrument based at least in part on the signal from the telecoil; and initiating, by the processing system, one or more actions based on the context of the hearing instrument.

Abstract: A wedge for securing in an open position a hinged door having opposite faces and an edge between the faces. The wedge is luminescent and includes a bottom surface, a top surface at an acute angle to the bottom surface, and a pair of opposite side surfaces extending between the top and bottom surfaces. The wedge further includes an indentation on the bottom and each of the side surfaces sized to fully engage the door edge and make substantial contact with the door edge and the opposite faces. The wedge may be used to identify an entrance or exit to a room during no or low-light emergency conditions by using a UV light source to locate the luminescent wedge and location of the open door.

Abstract: A thermoplastic resin composition contains an aromatic carbonate resin, a rubber modified graft copolymer comprising a discontinuous rubber phase dispersed in a continuous rigid thermoplastic phase, wherein at least a portion of the rigid thermoplastic phase is chemically grafted to the rubber phase, wherein the rubber phase of the copolymer is made by an aqueous emulsion polymerization in the presence of a (C.sub.30 -C.sub.108)polyacid surfactant, and a flame retarding amount of an organophosphorus flame retardant.

Abstract: There is provided a biodegradable composition as obtained from a melt comprising converted starch, a plasticizer and at least one member selected from alkenol homopolymers and/or alkenol copolymers which are combined under conditions sufficient to ensure uniform melt formation, in which the at least one member is present in the composition at a concentration of from 10 to 200 parts per 100 parts of dry converted starch.The invention further relates to methods of making the composition, and to articles made from said composition.

Abstract: A protective solution for the preservation of functional cells containing saccharose, and a phosphates buffer having a high concentration. The osmolarity of the solution is 330.+-.10 mOsm and its pH 7.3.+-.0.2. It can be mixed directly with red corpuscles of human or animal origin, with other blood cells such as leucocytes and platelets, and with cellular suspensions from various organs, either for their preservation for a long time, of the order of one week, in situ after thawing, or during transportation. The preferred composition is______________________________________ Adenine 0.085 g .+-. 0.010 Glucose 5 g .+-. 0.5 Saccharose 47 g .+-. 2 Monosodium phosphate monohydrate 0.75 g .+-. 0.08 Disodium phosphate dihydrate 4 g .+-. 0.5 Sodium chloride 2.5 g .+-. 0.
