Abstract: A hand-held optoelectronic test system comprising a cartridge including at least one light source and sensors prealigned to permit acquisition of electro-optic data from a fluid sample reacted with a reagent, such as upon a test membrane in a reaction zone, and a reader which processes the acquired data to identify a physical change in the fluid sample. The cartridge and reader are operable for separate predetermined or controllable finite numbers of tests before becoming disposable.

Abstract: A monolithic bail-delatch mechanism is provided for a module plugged into a cage. The bail-delatch mechanism is a single monolithic unit that includes a living hinge connecting a bail and a delatch clip. The living hinge, the bail, and the delatch clip may be made of a single injection molded plastic part. The bail may include cantilever hooks for securing the bail against the module in a latched position. The delatch clip may include a spring mechanism having two spring arms for locking the bail-delatch mechanism to the module, and a delatch fork having tines with wedges for releasing a post of the module from a latch tab of the cage.

Abstract: Electrical current in an electrical power distribution system, such as underground residential distribution or the like, is transferred through a current sensing bar from a transformer secondary to separate electrical service connections with residences or other sites of customer power users. The flow of electrical current and thus the amount of electrical power provided to individual users is measured at the current sensing bar rather than at the user's site or facility. This removes the need for watt-hour measurements at the user or customer site, and also thus removes the requirement for conventional meter reading crews or for automated meter reading equipment.

Abstract: Electrical current in an electrical power distribution system, such as at a power distribution transformer or the like, for an electrical utility is transferred through a current sensing connector lug mounted with an end of a user or consumer's service connection conductor or line. The lug is connectable to the power distribution transformer or secondary conductor, for connecting the user's service conductor to power from the distribution system. The flow of electrical current and thus the amount of electric power provided to an individual user is measured at the current sensing lug rather than at the user's site or facility, removing the need for watt-hour meters at the user or customer site, and also thus removing the requirement for conventional meter reading crews or for automated meter reading equipment. The current sensing lug also facilitates the accumulation of other utility data information, which formerly required a site visit by utility personnel.

Abstract: A system measures electrical energy usage and combines the measured energy usage with other utility commodity usage for communication and data collection. The system is capable of metering electrical power utility services to residential homes and apartments or other users and combining electrical usage and other utility metering functions for utilities for multiple utility end users. The system thus integrates and communicates the results of utility usage, and eliminates the need for an individual electric metering device for each end user. The system serves as a single metering data collection point for multiple utilities and facilitates interactive communication technologies between the utility service delivery points and utility consumers or consumer devices. The system also includes a plurality of meter ports and a memory for storing meter data from each metered user. The UCI provides for injection of broadband signals onto the service conductors from multiple broadband sources.

Abstract: A fiber optic module includes a first housing insert molded with an electromagnetic interference (EMI) shield, an optoelectronic subassembly mounted in the first housing, and a second housing mounted to the first housing to enclose the optoelectronic subassembly. The EMI shield includes a conductive mesh and conductive contact fingers. The first housing includes a non-conductive housing floor, non-conductive housing sidewalls, and a non-conductive nose defining at least one connector receptacle, wherein the housing floor and the housing sidewalls are injection molded through the mesh of the EMI shield to be integral with the nose and so that the fingers at least partially surround the nose.
