    Abstract: The present disclosure is directed to a system and method for interrogating radio frequency tags. In some implementations, a method includes A method includes successively polling, for a specified number of inventory cycles, a plurality of Radio Frequency Identification (RFID) tags in a first state. At least a first subset of the plurality of RFID tags transitions from the first state to a second state in response to the poll. After the specified number of inventory cycles, a command is transmitted to update at least a second subset of the plurality of RFID tags from the second state to first state. The plurality of RFID tags are subsequently polled after transmitting the update command.

    Abstract: A plate and fin type heat exchanger has a heat exchanger core made from a plurality of stacked, alternating first and second heat exchange plates of a generally inverted, U-shaped cross-section. Each plate has a top wall, closed peripheral sidewalls and open ends, and the open ends of the first plates are oriented at 90° to the open ends of the second plates. The sidewalls of the plates have end portions, which in adjacent plates, are aligned to form corners of the heat exchanger core. Opposed U-shaped manifold bodies are provided having open ends and lateral walls joined in a fluid tight manner to the aligned plate sidewall end portions. End plates close off the open ends of the U-shaped bodies to form manifolds. The corners formed by the aligned plate sidewall end portions allow for an improved connection between the heat exchanger core and the U-shaped manifold bodies. This helps to ensure that a fluid tight seal is created between the heat exchanger core and the manifold bodies when the components are joined together.
