Abstract: A plate heat exchanger comprises a plurality of heat exchanger plates (1). The plates are provided beside each other and permanently joined to each other to form a plate package having first plate interspaces and second plate interspaces. Each plate has a heat transfer area (20) and four porthole areas (21-24) defined by a porthole edge (25). Each of the porthole areas comprises an annular flat area (31) located at one of a primary and secondary level, and a set of inner portions (32) on the annular flat area at the other of the primary and secondary level. Each inner portion has an inner part adjoining the porthole edge and an outer segment adjoining the inner part and having an angular extension of at least 180°.

Abstract: A plate heat exchanger comprises a plurality of heat exchanger plates (1) formed of a metal sheet and permanently joined to each other by means of a braze material to form a plate package having first plate inter spaces (4) and second plate inter spaces (5). Each heat exchanger plate has a pattern forming a heat transfer area and a plurality of porthole areas. Each heat exchanger plate extends along a main extension plane (p). The areas extend, on one side of the heat exchanger plate, between a primary level (p?) at a distance from the main extension plane and a secondary level (p?) at a distance from and on an opposite side of the main extension plane. Each heat exchanger plate has a depth (d) defined by the distance between the primary level and the secondary level. The depth is equal to or less than 1.0 mm.

Abstract: A gasket assembly of a plate heat exchanger, comprising at least one gasket (3) and a package of heat exchanger plates (2) which are provided with inlet and outlet ports (4, 5, 6, 7) which constitute channels through the package and between the heat exchanger plates, whereby the heat exchanger plates are permanently joined in pairs to constitute cassettes (1), the gasket is disposed between the cassettes in a groove (12) in the heat exchanger plates and delimits in combination with the cassettes in every second space between plates a first flow passage for a first fluid, and the cassettes delimit a second flow passage for a second fluid. The gasket in the area around the ports comprises along its side facing the porthole a circumferential protruding bead (14). The invention also relates to a plate heat exchanger comprising the gasket unit, a heat exchanger plate and a gasket according to the invention.

Abstract: A method and a system (100) for transmission of a large amount of data over a first dedicated wireless link (A) at a first frequency, such as 2.4 GHz. If the signal strength is weak, the data is further compressed. If the signal strength is further weaker, a second wireless link (B) is used at a second frequency, such as 868 MHZ. The second wireless link (B) is at the same time used as a network system for exchange of information in which the nodes of the system operates as nodes in a multi-hop system.

Abstract: A technique for securely storing data within a memory is disclosed. In a preferred embodiment, the technique is realized by encrypting the data using a non-verifiable personal identifier, and then encrypting a reminder using the same non-verifiable personal identifier. The encrypted data and the encrypted reminder are then stored in the memory. The stored encrypted data and the stored encrypted reminder can only be correctly decrypted using the non-verifiable personal identifier. Also, a correctly decrypted reminder provides an indication of correctly decrypted data. The non-verifiable personal identifier is not stored in the memory so as to insure security of the system.

Abstract: A method and system are disclosed whereby one or more communication devices can automatically switch between physical communication interfaces on an as needed basis. A first (sending) device attempts to initiate communications with another device using one interface at a time. These attempts are made in accordance with a predetermined priority list. If the second device responds to any such interface selected, a communication “channel” is then set up. Once such a channel is set up, the devices can use the channel to negotiate for use of one of the other communication interfaces, if necessary. If the communication is interrupted inadvertently, either device can attempt to reinitiate the communication in accordance with the priority list.
