Reliably updating a messaging system
A messaging system enables client applications to send and receive messages. The messaging system includes independent component programs performing different functions of the messaging system. The component programs include persistent connection managers that maintain connections with the client applications, a dispatcher that establishes connections, and a message router that sends received messages to recipient applications through corresponding connections.

Antenna having flexible feed structure with components
Electronic devices may include antenna structures. The antenna structures may form an antenna having first and second feeds at different locations. Transceiver circuitry for transmitting and receiving radio-frequency antenna signals may be mounted on one end of a printed circuit board. Transmission line structures may be used to convey signals between an opposing end of the printed circuit board and the transceiver circuitry. The printed circuit board may be coupled to an antenna feed structure formed from a flexible printed circuit using solder connections. The flexible printed circuit may have a bend and may be screwed to conductive electronic device housing structures using one or more screws at one or more respective antenna feed terminals. Electrical components such as an amplifier circuit and filter circuitry may be mounted on the flexible printed circuit. |

E-Z fit antenna base
An apparatus for securing an antenna to a surface by means of an antenna base and stand off with internal cable routing, which prevents any cables showing. With only one drilled hole at time of installation. With a device for holding an antenna vertical yet allowing said antenna to be lowered easily and quickly without tools or clumsy mechanisms attached to the antenna. A unique way to eliminate water penetration by means of clamping into the surface with gaskets and o-rings in a simple, relatively unskilled process. Therefore eliminating troublesome holes and sharp protrusions made by screws. While allowing free movement of the antenna for raising and lowering prepossess. A one hole, one nut installation that can be preformed by a single relatively unskilled person. Simple to manufacture with a minimal number of parts. With a beautiful streamlined appearance, that can be used for mounting any standard antenna. |

Method for fabricating a nonaqueous electrolyte secondary battery
A nonaqueous electrolyte secondary battery includes: a positive electrode 4 including a positive electrode current collector and a positive electrode mixture layer containing a positive electrode active material and a binder, the positive electrode mixture layer being provided on the positive electrode current collector; a negative electrode 5; a porous insulating layer 6 interposed between the positive electrode 4 and the negative electrode 5; and a nonaqueous electrolyte. The positive electrode 4 has a tensile extension percentage of equal to or higher than 3.0%. The positive electrode current collector is made of aluminum containing iron. In this manner, the tensile extension percentage of the positive electrode is increased without a decrease in capacity of the nonaqueous electrolyte secondary battery. Accordingly, even when the nonaqueous electrolyte secondary battery is destroyed by crush, occurrence of short-circuit in the nonaqueous electrolyte secondary battery can be suppressed. |
