Abstract: Transducer systems with reduced acoustic noise coupling are disclosed herein. In some embodiments, a transducer system includes pressure balancing features to prevent a floating portion of the transducer system from contacting a fixed portion of the transducer system, or to reduce the degree to which the floating portion is urged into contact with the fixed portion by process pressure or atmospheric pressure. In some embodiments, a transducer system includes one or more acoustic dampening elements, interruption grooves, annular projections, or dampening washers to reduce acoustic noise coupling between various components of the transducer system or between the transducer system and a flowcell in which the transducer system is mounted.

Abstract: An apparatus and method for determining temperature is disclosed. An ultrasonic signal is generated that propagates through a buffer and a portion of the signal is reflected at an interface. A time of flight is measured between generating the ultrasonic signal and detecting the reflected portion. The temperature is determined based on the time of flight of the reflected signal.

Abstract: A bicycle comprises a bicycle frame and a rear wheel suspension system that is attached to the frame. The rear wheel suspension system comprises a rear wheel swingarm and a shock absorber that is coupled to the swingarm. A change in vertical wheel travel (?VWT) of the rear wheel is related to a change in the length of the shock absorber (?SL), providing a shock rate (SR). The shock rate (SR) changes throughout the vertical wheel travel of the rear wheel, such that the change in the shock rate dSR/dVWT has a change in sign as the rear wheel travels through its vertical wheel travel. In each case, the rate of change of the shock includes a change in sign, from positive to negative or from negative to positive. In some embodiments, the swingarm may be attached to the frame at a single pivot point or through a linkage system.

Abstract: Automatic gain control (AGC) and synchronisation acquisition by a communication unit in a wireless communication system, e.g. a Universal Mobile Telecommunication System (UMTS) system, is described. AGC is performed using a downlink beacon function, for example a power level (Pbeacon) . Amplitude-equalising (limiting) is performed as part of synchronisation acquisition. Separate AGC processes are used for different stages of synchronisation acquisition. One AGC process uses a peak power (P(k)) of a received signal over a frame. Another AGC process uses a peak power (P(k)) of a received signal over only a portion of a frame, the portion comprising an initial synchronisation code. Another AGC process uses measurements of a received signal (P0(k)) taken in a downlink beacon timeslot. These processes tend to provide tolerance to a varying number of codes (M) transmitted on a timeslot-by-timeslot basis and robust initial synchronisation in the presence of strong uplink interference.

Abstract: A method, arrangement (512) and communication receiver (500) for SNIR estimation of a received signal, by: deriving (512A) an estimation {circumflex over (Z)} of SNIR of the received signal in accordance with the relation Z ^ = [ E ? { ? r ? ( t ) ? } ] 2 E ? { r 2 ? ( t ) } - [ E ? { ? r ? ( t ) ? } ] 2 , where E represents mean value and r(t) represents the level of the received signal; and correcting (512B, 512C) the estimation {circumflex over (Z)} to produce a corrected estimation Z based on the relation Z=?({circumflex over (Z)})×{circumflex over (Z)}, where ?({circumflex over (Z)}) represents a correction factor. The estimation may be corrected by calculating the correction factor, retrieving the correction factor from a predetermined table (512B) or retrieving the corrected estimation from a predetermined table. The correction may be effected by adding to a logarithmic estimation a logarithmic correction factor.

Abstract: Embodiments of the invention provide a controller, in a cellular wireless network for cancellation of interference from neighboring cells. Logic in the controller determines channel quality of a radio channel between a first base station and a UE. Scheduling logic causes the first base station and a second base station to adjust the number of data streams used for communication within a time period, as a function of the channel quality. Other embodiments provide an apparatus for reducing interference in a receiver that receives N data streams. Signal processing logic receives the N data streams, where N-M of the data streams represent interference with respect to M desired data streams, and cancels the N-M data streams so as to receive the M desired data streams. The N data streams may be received from multiple base stations, or multiple UEs.
