Abstract: Methods and apparatus for moving aliquot samples of fluid using a shuttle valve are disclosed.

Abstract: A wireless communication system comprises a first wireless communication device for a first team member, and a second wireless communication device for a second team member. The first wireless communication device comprises a microphone and a transmitter for transmitting an oral message via a first wireless communication protocol. The second wireless communication device comprises a main transceiver, a headset, and a support for mounting the main transceiver to the second team member remotely from the headset. The main transceiver receives the oral message from the first wireless communication device via the first communication protocol and retransmits the oral message via a second wireless communication protocol to the headset for generating audio corresponding to the oral message. The second wireless communication protocol operates at a lower power than the first wireless communication protocol, and the first communication protocol operates over a longer range than second wireless communication protocol.

Abstract: Automated sample injection apparatus, multiport valves, and chromatography systems containing an automated sample injection apparatus and/or a multiport valve are disclosed. Methods of making and using automated sample injection apparatus and multiport valves within chromatography systems are also disclosed.

Abstract: The invention is directed to a bed bug monitoring device comprising a bed bug attractant element and a harborage section comprising a support member having a traversable surface and one or more protuberances depending therefrom. The harborage defines at least one entrance through which bed bugs attracted to the device can enter. The device can further include a base section placed over at least a portion of the traversable surface and adapted to by placed flush with the surface against which the device is to be placed.

Abstract: A smoke detector having a sound quality enhancement chamber for increasing the sound quality of alarms produced by a sound producing device in the smoke detector. In at least one embodiment, the sound quality enhancement chamber is formed by a housing and a plate such that the chamber is in communication with a sound producing device, which may be a speaker, for producing sounds, such as a human voice, with enhanced quality. The sound quality enhancement chamber acts as a spring and increases the quality of the sounds produced by the sound producing device of the smoke detector. In at least one embodiment, the sound quality enhancement chamber enables a smoke detector to emit a parent's voice that is clear and easily understandable.
