One embodiment is directed to a method of reading RFID tags in an interconnection system comprising at least one port. The method comprises initiating a localized read transaction to read any RFID tag attached to a first connector and any RFID tag attached to a second connector inserted into the port. The method further comprises, as a part of the localized read transaction, reading any RFID tag configured to respond to a first type of RFID interrogation signal, wherein the first connector comprises an attached RFID tag that is configured to respond to the first type of RFID interrogation signal; and, as a part of the localized read transaction, reading any RFID tag configured to respond to a second type of RFID interrogation signal, wherein the second connector comprises an attached RFID tag that is configured to respond to the second type of RFID interrogation signal. Other embodiments are disclosed.

An internally switched female receptacle or connector for use with IEC 60309-2 configuration plugs and the like. Various plug-latching and plug-actuated safety interlock arrangements coordinate strictly axial plug movement relative to the receptacle with the closing and opening of sleeve contacts and terminal pressure contacts. A continuous ground feature ensures grounding of the primary electrical circuit throughout plug insertion and withdrawal. An optional low-current lighting control circuit powers an LED status indicator. A modular clocking design enables variable angular positioning of the terminals during manufacture.

An LED (light emitting diode) panel. In particular, an LED panel that is part of a modular system used to construct a wall mounted LED video screen. An LED panel includes a chassis and an LED tile including a plurality of surface mount devices attached thereto. The LED tile is removably mounted to a front of the chassis, and further includes: a first power connector and a first data connector; and a connector assembly mounted on the chassis. The connector assembly includes a support board; a second power connector; a second data connector; and a biasing member arranged to urge the support board in a direction towards the front of the chassis, such that the second power connector and second data connector engage with the first power connector and first data connector, respectively.

A downhole system including a gun string configured to be deployed into a wellbore, the gun string including plural gun assemblies. A detonator block attached to a given gun assembly of the plural gun assemblies. The detonator block includes a switch assembly. The switch assembly includes a communication unit (CU) configured to receive, from an external controller, a fire command to activate a detonator associated with the detonator block, a measuring unit configured to measure a parameter (V) at the switch assembly, and a computing core (CC) configured to locally make a decision whether to activate or not the detonator, after the fire command is received from the external controller, based on whether a voltage measured by the measuring unit at the switch assembly is larger or not than a threshold voltage.

The invention relates to a power adapter comprising a first prong (12) rotatable between a stowed configuration and a deployed configuration; and a second prong (13,14) rotatable in an opposing direction between a stowed configuration and a deployed configuration. A deployment mechanism associated with the first and second prongs (12,13, 14) causes their movement between the stowed and the deployed configurations. The deployment mechanism comprises a cam (see FIG. 10) coupled to at least one of the first and second prongs (12,13, 14) and arranged to act on the other prong such that movement of the cam translates to rotation of the prongs. It will be appreciated that the invention provides for a collapsible power adapter which is smaller, more user-friendly and cost effective that conventional power adapters.

Improvements in machine walls to construct a building or house is disclosed. Adjacent side of the wall sections are tapered and dovetailed that lock-in-place. The dovetails are spaced to reduce the height that one section must be lifted to engage in an adjoining wall section. The footers/base plate will also have integrated earthquake or hurricane hold-downs in the footer/base plate that aligns and can be secured from the foundation to the wall sections. The connection of the wall section to the foundation to have counter flashing at the concrete insert and the wall-to-wall sections can be self-flashed. The wall sections can have GPS locators for positioning the wall sections. Plumbing and electrical conduit creating circuits that can be integrated into the walls and are connected sealed or bonded together.
