Abstract: A passenger transport system includes a bus system transferring data between a central control unit and a plurality of field devices. In a failure detection method, the field devices are configured in an unbranched chain configuration and the control unit transmits a test telegram to a first field device to start a monitoring cycle during which each field device receiving the test telegram forwards the test telegram to a next field device in the chain. During the monitoring cycle, the control unit monitors a communication between the field devices occurring via the bus system, in order to detect when a field device does not forward the test telegram. A data volume transmitted via the bus system during the failure detection method is significantly reduced in comparison to conventional failure tests such that failures can be recognized more quickly and/or simpler hardware and/or software can be used.

Abstract: An implant or endoprosthesis suitable to be implanted in human or animal tissue includes two (or more than two) parts to be joined in situ. Each one of the parts includes a joining location, the two joining locations facing each other when the device parts are positioned for being joined together, wherein one of the joining locations includes a material which is liquefiable by mechanical vibration and the other one of the joining locations includes a material which is not liquefiable by mechanical vibration and a structure (e.g. undercut cavities or protrusions) suitable for forming a positive fit connection with the liquefiable material. The joining process is effected by pressing the two device parts against each other and by applying ultrasonic vibration to one of the device parts when the two parts are positioned relative to each other such that the two joining locations are in contact with each other.

Abstract: A surgical method is provided, the method including the steps of: providing an artificial or allograft flexible planar structure; providing an implant, the implant including material liquefiable by mechanical oscillation, exposing a surface region of hard tissue or hard tissue substitute material; positioning the implant on an exposed area of the hard tissue or hard tissue substitute material; and fastening the implant to the hard tissue or hard tissue substitute material by impinging the proximal end of the implant with mechanical oscillation and simultaneously pressing the implant against the hard tissue or hard tissue substitute material while the distal end of the implant protrudes into a cavity of the hard tissue or hard tissue substitute material and regions of the liquefiable material are in contact with the hard tissue or hard tissue substitute material, and thereby liquefying at least a portion of the liquefiable material, and letting the liquefiable material resolidify.

Abstract: For fixedly implanting a device for material or signal delivery or acquisition or a part of such a device in a human or animal body, an opening is provided in hard tissue of the body, the opening reaching through a hard tissue layer, e.g. through a cortical bone layer into cancellous bone underneath. The device includes a plug portion and/or a cover portion which includes a ring of a material having thermoplastic properties extending around the plug portion or on a tissue facing surface of the cover portion. The opening provided in the hard tissue has a cross section at least in the area of its mouth that is adapted to the plug or cover portion such that the plug portion can be introduced through the mouth of the opening or the cover portion can be positioned over the mouth of the opening such that the ring extends around the opening, along its wall and/or on the hard tissue surface around its mouth.

Abstract: An RF module adapted for direct surface mounting to the top surface of the front end of the motherboard of a picocell. The module comprises a printed circuit board having a plurality of direct surface mounted electrical components defining respective signal transmit and receive sections for RF signals. The signal transmit section is defined by at least a transmit bandpass filter, a power amplifier, an isolator, a coupler, and a duplexer. The signal receive section is defined by at least the duplexer, a receive low pass filter, a low-noise amplifier, and a receive bandpass filter. A lid covers selected ones of the electrical components except for at least the power amplifier. A plurality of through-holes defined in the printed circuit board below the amplifier allow for the dissipation of heat created by the amplifier. At least one aperture in the board is adapted to accept a screw or the like for securing the module to the motherboard of the picocell.
