In order to be able to solder without difficulties the solder onto work pieces that exhibit sensitivity to breakage it is proposed that the solder is heated, is applied to the work piece that is supported in particular in a spring-mounted manner, and is soldered-on subject to the influence of ultrasound.

Abstract: A technique for performing layer 2 processing is described. In a method implementation of this technique, at least one first RLC SDU is created from one or more first RLC PDUs. It is assumed here that the first RLC SDU belongs to an incomplete RLC SDU set that is to comprise at least one second RLC SDU, and that the second RLC SDU is to be created from at least one second RLC PDU not yet available. In a next step, a first PDCP function is applied to the first RLC SDU to create a data packet. The RLC function is only performed after the second RLC PDU has become available (or after an RLC time-out). Then, after the RLC function has been performed, the data packet is released to a second PDCP function.

Abstract: The invention relates to a method for operating a vehicle comprising at least one steered axle and at least one driven axle, wherein at least the driven axle has at least two wheel-hub electric motors that are integrated in the respective drive wheel. In addition, an electronic control unit (BLDC controller module 1, BLDC controller module 2) is provided for the wheel-hub motors (wheel-hub motor 1, wheel hub motor 2) forming an electronic differential. Sensors detect signals (Hall signals) that correspond to the driving defaults (default). According to the invention, correction factors for default values (default) for controlling the wheel-hub motors (wheel-hub motor 1, wheel hub motor 2) are determined from the sensor signals (speed), the position of the accelerator pedal (gas pedal) or accelerator throttle and the steering angle (steering angle generator) by means of an interface module and said factors are forwarded to the relevant motor control units (BLDC controller module 1, BLDC controller module 2).

Abstract: A head-rest of a vehicle seat with a deformable central supporting body which forms an impact zone for the head of a vehicle occupant and into which the kinetic energy of the head in the event of an accident is admitted. On both sides of the impact zone the central supporting bodies are joined by lateral supporting surfaces which are extendable out of the plane of the head-rest in the direction of travel in order to laterally support the head. In order to avoid or at least to reduce the risk of a cervical-spine whiplash injury, it is proposed according to the invention that the head-rest comprises a device for absorbing the energy admitted into the central supporting body and for outputting the absorbed energy in order to activate lateral supporting surfaces.

Abstract: A distributed memory architecture for a layer 2 processing circuit chip (50) is described. In one implementation, the layer 2 processing circuit chip (50) comprises an external memory interface configured to provide access to data packets stored in an external memory (52), a layer 2 processor (54) coupled to the external memory interface (56) and configured to process data packets retrieved from the external memory (56) to generate RLC SDUs, and an on-chip memory (58) coupled to the layer 2 processor (54) and configured to store the RLC PDUs generated by the layer 2 processor (54) prior to their transmission. Upon a request to retransmit an RLC PDU, the layer 2 processor (54) is configured to selectively read the RLC PDU to be retransmitted from the on-chip memory (58) or a data packet comprising the RLC PDU to be retransmitted from the external memory (52).

Abstract: A pressure sensing catheter having a pressure sensor and an antenna that is coupled to the pressure sensor, e.g., by a connector, are provided. The pressure sensor can be adapted to measure a pressure surrounding the catheter, and the antenna can be adapted to telemetrically communicate the measured pressure to an external device. In an exemplary embodiment, the antenna, pressure sensor, and/or connector are hermetically sealed, e.g., by the catheter and/or a coating, to prevent the antenna, pressure sensor, and connector from coming into contact with fluid, thereby allowing the catheter to be permanently implanted or otherwise used for long term use. Exemplary methods for manufacturing and using pressure sensing catheters are also provided.
