A plant package for an artificial aquarium plant including a card member having a front face and a shaped shell member affixed to the front face by a peripheral bonding flange. The shell member has an upper section including a plant base holding pocket with a top edge. The top edge is free of the card member. The bottom portion of the plant base holding pocket is shaped to confine a base of the artificial aquarium plant with the top portion being restricted and shaped to overlay and support one or more plant stems of the artificial aquarium plant. A lower section of the shell member is designed with raised ridges reinforcing the shell member and defining an indicia window portion.

A grid communication system provides distributed processing of business workflows. Each node has a core with a small footprint which provides control of business process and data flow and synchronization. The node controller communicates with applications and with other nodes through the use of messages. Messages are processed by the node controller according to a set of rules. The rules reside in a versioned repository. The rules may be set or modified through the use of messages from other nodes, allowing for enterprise control of individual nodes. The node controller includes a plurality of adapters for converting data and/or messages to and from formats for different applications.

Presented is a sensor that includes a magnetoresistive (MR) sensing device to sense a magnetic field and to produce an AC signal voltage proportional to the sensed magnetic field. The sensor also includes circuitry, coupled to the MR sensing device, to remove DC offset from the AC signal voltage. The DC offset may be related to the hysteresis characteristics of the MR sensing device. To remove DC offset, the circuitry may obtain an averaged DC offset and subtract the averaged DC offset from the AC signal voltage to produce a sensor output signal.

An integrated circuit includes a monitor node adapted to receive a monitored signal. The integrated circuit also includes a multi-purpose node. The integrated circuit is adapted to receive and store a threshold presented at the multi-purpose node during a first time period. The integrated circuit is also adapted to output a fault signal from the multi-purpose node at a time after the predetermined time period. The fault signal is indicative of a relationship between the monitored signal and the threshold. With this arrangement, the multi-purpose node achieves at least two functions.
