Abstract: A flexible cover configured to fit over a J-hook weight bar support comprising a first tubular sleeve comprising a flexible material with an open end and a closed end, a second tubular sleeve comprising a flexible material with an open end and a closed end, and a length of flexible material connecting the first tubular sleeve open end to the second tubular sleeve open end. The first tubular sleeve is configured to fit over a vertical portion of the J-hook weight bar support, the second tubular sleeve is configured to fit over a horizontal portion of the J-hook weight bar support such that the length of flexible material sits on an inside surface of the J-hook weight bar support, and the length of flexible material is abrasion resistant.

Abstract: A pool of messages, e.g., e-mails and/or other electronic documents that each correspond to a communication from a sender to a recipient, is analyzed to identify communication chains between a source and a target. Sender and recipient identifiers extracted from the messages are used to detect direct and indirect communication links between pairs of entities. Information related to the identified communication chains can be presented to a user via an interactive network graph that supports iterative analysis of the communication-chain data.

Abstract: A pool of messages, e.g., e-mails and/or other electronic documents that each correspond to a communication from a sender to a recipient, is analyzed to identify communication chains between a source and a target. Sender and recipient identifiers extracted from the messages are used to detect communication links between pairs of entities. Indirect chains of any desired length can be found by iteratively tracing a communication path one step forward from the source, then one step backward from the target, and so on; at each new step, entities at end points of the forward paths and backward paths are compared to detect any entities that complete a communication chain from source to target. Information related to the identified communication chains can be presented to a user via an interactive report that supports iterative analysis of the communication-chain data.

Abstract: A fuel cell assembly includes a fuel cell, a fuel cell housing, and a diaphragm. The fuel cell housing includes an endwall and an inlet port extending through said endwall. The inlet port is for admitting a breath sample into the housing. The diaphragm is coupled within the housing such that a cavity is defined between the housing and the diaphragm. The fuel cell is positioned within the cavity and is substantially concentrically aligned with respect to the inlet port.
