Abstract: An oxygen generator for use in a passenger aircraft comprises an oxygen generating substance for generating oxygen gas after being activated; an activating substance for activating the oxygen generating substance; a pyroelectric igniter for igniting the activating substance upon receiving an electric trigger input; a housing defining a gas-tight chamber, accommodating the oxygen generating substance, the activating substance and the pyroelectric igniter; at least two electric conductors, coupled to the pyroelectric igniter and extending through a passage in the housing between an interior of the gas-tight chamber and an exterior of the gas-tight chamber; and at least one of a gas-tight glass-to-metal sealing and a gas-tight ceramic-to-metal sealing, sealing the at least two electric conductors with respect to the housing at the passage.

Abstract: Technologies are described for a collapsible cart and method of assembly. The cart has a cart base and a removable cart table top. The cart base has a rectangular cart frame and a foldable leg extending from a first side, proximate each corner, of the rectangular cart frame. Each foldable leg is configured to rotate about a first end and to lock into an extended orientation, and to rotate into a folded orientation and become proximate the rectangular cart frame. A clasp assembly is proximate a second end of each of the foldable legs and are configured to clasp arms proximate each corner of the removable cart table top.

Abstract: A method includes receiving, from a user device, a request to access a long term evolution (LTE) network; sending, to a group of servers, a query to obtain information associated with a respective traffic condition and processing capacity associated with each of the group of servers; identifying a particular server, of the group of servers, via which to establish a communication session with the user device based on a determination that the particular server has a reserve processing capacity that is greater than a respective reserve processing capacity associated with the each other one of the group of servers, where the reserve processing capacity is based on a traffic condition and processing capacity associated with the particular server; and sending, to the particular server, an instruction to establish the communication session, where sending the instruction enables the particular server to establish the communication session via which the user device is to access the network.
