Patent number: 8578781Abstract: The present invention relates to a device to indicate a predetermined critical corrosion of a metallic structure located in soil, water or concrete environment. The device comprises a probe that has a closed tubular container intended to contain a pressurized medium, and that has a wall thickness t that corresponds to the predetermined critical corrosion. A protective coating is arranged essentially over the entire outside of the container with the exception of a surface that is intended to be subjected to corrosion attack. The container is allowed to corrode so that the container becomes perforated, whereupon the pressure of the pressurized medium falls. The pressure change is measured by means of a pressure gauge, and in this way, information is obtained about the fact that the corrosion has reached the predetermined critical level.Type: GrantFiled: April 19, 2010Date of Patent: November 12, 2013Assignee: SCS Engineering ABInventor: Anders Dahlström

Patent number: 6650294Abstract: Broadband multi-resonant antennas utilize capacitive coupling between multiple conductive plates for compact antenna applications. The number and design of conductive plates may be set to achieve the desired bandwidth. In one exemplary embodiment the antenna may be designed for four resonant frequencies and may include three L shaped legs each including a micro-strip conductive plate and connection pin, with configurations approximately parallel to one another. The center L shaped leg may be a feed patch with a feed pin connected to a transmitter, receiver, or transceiver. The upper L shaped leg may be a dual band main patch and ground pin. The dual band main patch may have two different branches with different lengths and areas to handle three of four desired resonant frequencies. The lower L shaped leg may be a parasitic high band patch and ground pin designed to handle one of the two higher desired resonant frequencies.Type: GrantFiled: November 26, 2001Date of Patent: November 18, 2003Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Zhinong Ying, Anders Dahlström

Patent number: 6456250Abstract: A multi frequency band antenna with a low band portion (LB) tuned to a low frequency band, and a first high band portion (HB1) tuned to a first high frequency band at higher frequencies than the low frequency band. The low band portion (LB) and the first high band portion (HB1) have a common first grounding point (GP1), a common feeding point (FP) for feeding input signals to the antenna and for outputting signals from the antenna, and a first conductor portion (CP1), which forms part of the low band portion (LB) and of the first high band portion (HB1). The first conductor portion (CP1) is electrically connected to the first grounding point (GP1) and to the common feeding point (FP), A second high band portion (HB2) is coupled to the first conductor portion (CP1) and tuned to a second high frequency band at a higher frequency than the low frequency band and different from the first high frequency band.Type: GrantFiled: May 22, 2001Date of Patent: September 24, 2002Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Zhinong Ying, Anders Dahlström

Publication number: 20010050643Abstract: A small, inexpensive, built-in planar inverted F-type antenna (PIFA) with a parallel meandering parasitic element having a wide bandwidth to facilitate wireless, short range communications between devices operating in the Bluetooth frequency range is disclosed. The parasitic element is placed on the same substrate as the main antenna element and is grounded at one end. The feeding pin of the PIFA is proximal to the ground pin of the parasitic element. The coupling of the meandering, parasitic element to the main antenna results in two resonances. These two resonances are adjusted to be adjacent to each other in order to realize a broader resonance.Type: ApplicationFiled: February 22, 2000Publication date: December 13, 2001Inventors: Igor Egorov, Anders Dahlstrom
