Abstract: A leak detection module (LDM) includes a three-position proportional solenoid valve having a charcoal canister port fluidly connected to a charcoal canister connection, a pump port fluidly connected to a first port of a pump, and an atmospheric port fluidly connected to a second port of a pump. The atmospheric port is fluidly connected to atmosphere. A longitudinally movable rod has a seal with first, second and third positions. The seal obstructs the pump port and fluidly connects the charcoal canister port and the atmospheric port in the first position, obstructs the atmospheric portion and fluidly connects the charcoal canister port and the pump port in the second position, and obstructs the charcoal canister port in the third position which fluidly blocks the pump port from the atmospheric port and fluidly separates the first and second ports with the seal.

Abstract: A leak detection module (LDM) includes a housing including first and second valve cavities respectively having first and second walls respectively extending to first and second openings. The first and second walls respectively include first and second holes. The housing has an atmospheric port, a charcoal canister port, and an electrical connector. First and second solenoid valves are arranged within the housing and are respectively received in the first and second cavities and extend out of the first and second openings. A pump is arranged within the housing and includes first and second pump ports respectively coupled to the first and second holes. An electrical connector assembly is arranged within the housing and is coupled to the electrical connector. The electrical connector assembly is electrically connected to the first and second solenoid valves, and the pump.

Abstract: The invention is directed towards a method, computer program, computer program product and a traffic amplification device (30) for assisting in the testing of performance of a layer 3 proxy device (12) as well as a testing system comprising such a traffic amplification device. The traffic amplification device (30) obtains a first message (M1) from at least one client devices (14) and intended for a server device (22), where the first message comprises a request for processing, sends a plurality of second messages (M2) to the proxy device (12) in a number corresponding to a desired degree of traffic amplification, where each second message comprises the request for processing, receives the second messages in return from the proxy device (12), selects one of the received second messages, and forwards (FM1) the request for processing of the selected second message to the server device (22) for being processed. It is also possible to handle responses (M3) from the server device in a similar manner.

Abstract: A data call between at least two internetworked computers is established using a central server. Once the data call is in place, prerecorded motion video is shared between the two computers by creating a streaming video server on one user's computer for streaming the prerecorded motion video simultaneously to both users as clients of the streaming server. Either user can pause, rewind, or fast forward the streamed video as it is viewed by both users.
