A service module incorporated within the network infrastructure intercepts packets communicated between a client and a server to determine whether the connection corresponds to an email service. If so, the service module breaks the connection by terminating the connection with the client at the service module and opening a separate connection between the service module and the server. Packets communicated between the client and the server may then be redirected to an email compression application that monitors messages communicated between the client and the server and processes the messages in accordance with the state of the email session. For messages corresponding to connection establishment, user authentication and other protocol-specific messages, for example, the email compression application may be configured to forward the messages to the originally intended destination. Messages corresponding to an email message data, however, are buffered within the email compression application. Once the entire message has been received, the email compression application may strip the message headers and any protocol-specific data, compress the data and attach new message headers corresponding to the compressed email message. The compressed and reformatted email message is then reinserted into the data stream for transmission to the intended destination. Because compression may occur between the server and client, compression may be performed without requiring special processing by the server before email messages are sent. Furthermore, because the email messages may be compressed in a format that can be readily decompressed using decompression libraries incorporated within the operating system of client devices, such as the CAB format or GZIP format, the client may decompress received email messages utilizing software already incorporated within the operating system of the client device, without requiring download or installation of special decompression software and/or coordination of compression/decompression of email messages with the server or sending party.

A video compression system is disclosed that is optimized to take advantage of the types of redundancies typically occurring on computer screens and the types of video loss acceptable to real time interactive computer users. It automatically adapts to a wide variety of changing network bandwidth conditions and can accommodate any video resolution and an unlimited number of colors. The disclosed video compression encoder can be implemented with either hardware or software and it compresses the source video into a series of data packets that are a fixed length of 8 bits or more. Sequences of one or more of these packets create unique encoding “commands” that can be sent over any network and easily decoded (decompressed) with either software or hardware. The commands include 3 dimensional copying (horizontal, vertical and time) and unique efficiencies for screen segments that are comprised of only two colors (such as text). Embodiments are also disclosed that improve the video compression depending on the popularity of pixel colors.

A spring retainer (60) for a syringe (10) that has a barrel (40), a plunger (20), a spring (90) and a retractable needle (50) that can couple with the plunger for spring-driven retraction of the coupled needle and plunger. The spring retainer has first (70) and second (80) body members that cooperate to releasably maintain the spring in a compressed state until the plunger is coupled to the retractable needle after depression of the plunger to deliver the fluid contents of the syringe. Depression of the plunger triggers rotational disengagement of the first and second body members to allow decompression of the spring which forces retraction of the needle into the barrel. Rotational disengagement of the first and second body members also assists rotation of the plunger into a final, inoperable position.

A retractable syringe (10) and plunger (20) therefore are provided, the syringe having a barrel (20), a retractable needle mount (40) to which is mounted or is mountable a needle (11), and a plunger (80), the plunger comprising an initially compressed spring (60), a means for engaging the retractable needle mount, an integrally formed plunger seal (22) and a removable controlling means (70) for facilitating control of the rate of retraction of needle mount when engaged with plunger. The needle mount is held in the barrel by a holding means which prevents inadvertent retraction of the needle mount when the plunger is withdrawn to fill the syringe. The holding means comprises a plurality of clips (196A, 196B, 196C) that may be integrally formed with the barrel or may be present on a cap mounted to the barrel. An ejector means (52) is also provided, whereby plunger depression can urge the ejector means to release the needle from the holding means and thereby allow retraction of the needle mount following decompression of the spring.

A pressure exchanger for transferring pressure energy from a relatively high-pressure fluid stream to another relatively low-pressure fluid stream is provided. A ducted rotor is positioned on a central axle between two end covers inside a pressure vessel with a coaxial inlet and outlet pair that is in communication with a pair of low pressure ports having inclination forming an inlet tangential velocity vector in the direction of rotor rotation and an outlet tangential velocity vector in opposite direction imparting a rotational momentum on rotor. A pair of high-pressure ports is adapted for flow without inclination and imparts no momentum to rotor and flow can be varied without impacting the rotor's RPM. The end covers have a sloped surface following a flat sealing area that increases the clearance in the direction of rotation causing increased outflow during depressurization and lower duct pressure before duct is exposed to low pressure port and furthermore causing increased inflow during the pressurization phase before duct is exposed to the high pressure port, which will dissipate pressure energy as opposed to producing cavitation or pressure waves with result wear and noise.
