Abstract: A method for controlling at least one radial blower in a cooling system, wherein the radial blower comprises a housing in which a shaft is rotationally mounted, which receives at least one impeller wheel of a compressor at one end, which is secured to the housing, and the housing comprises at least one radial bearing and at least one axial bearing via which the shaft is rotationally mounted in the housing, and said radial blower also comprises a motor which is driven by a rotor and a stator and which drives the shaft, wherein, by means of at least one laser Doppler vibrometer assigned to the shaft, operating points of the shaft are detected and forwarded to a controller for determining an operating status of the radial blower.

Abstract: A radial blower, in particular for a cooling machine, comprising a housing in which a shaft is rotationally mounted, which receives at least one impeller wheel of a compressor at one end, which is secured to the housing, comprising at least one radial bearing and at least one axial bearing via which the shaft is rotationally mounted in the housing, and comprising a motor driven by a rotor and a stator and provided between the first and the second radial bearing, wherein at least one channel having a pressure connection for a pressure medium to be supplied is provided in the housing, which channel feeds into a rotor space formed between the shaft and the housing and extending from the impeller wheel to the radial bearing or axial bearing, which is provided next to the impeller wheel.

Abstract: A coupled to at least one server via a network includes a display device configured to display a base game to a player playing at the gaming machine, and a controller coupled to the display device. The controller is configured to determine an outcome during play of the base game, and award at least one token based on the outcome of the base game, wherein a value of the token based on as additional play of the base game by the player.

Abstract: A method includes: receiving a burst including payload and a synchronization field, wherein the synchronization field contains a synchronization pattern; selecting, from a plurality of expected synchronization patterns, a target synchronization pattern dependent on an operating mode; comparing the received synchronization pattern against the target synchronization pattern; and if the received synchronization pattern is of the target synchronization pattern, processing the payload; otherwise, discarding the burst.

Abstract: In a time division multiple access system, a fixed end device (102) receives a first requested call type. Based on the first requested call type, the fixed end device dynamically sets a first slotting structure as an existing slotting structure for the inbound and outbound channels. When a second requested call type is received, the fixed end determines whether to grant or deny the second requested call type and/or whether to maintain or dynamically change the existing slotting structure.

Abstract: A communication device (100) for duplex communication that includes: a transmitter (106) for transmitting a first voice signal encoded at a first voice coding rate and including first voice data, first error correction data having a first error correction rate and first control data; a receiver (108) for receiving a second signal having a first signal quality and including second control data; and a processing device (118) adapted for performing an algorithm for, estimating the first signal quality, operating in a first mode of operation when the signal quality estimation is above a threshold, wherein the first voice coding rate is adjusted as a function of the first and second control data, and operating in a second mode of operation when the signal quality estimation is below the threshold, wherein the first error correction rate is adjusted as a function of the first and second control data.

Abstract: Apparatus (50) for enabling group duplex communication in a wireless communications system (100) that includes a receiving device for receiving a first (14), second (24) and third (34) individual encoded voice signal from a first (10), second (20) and third (30) communications unit a over corresponding first (12), second (22) and third (32) communications resources, the first, second and third encoded signals being a function of respective first, second and third original voice signals; a processing device for generating at least one combined voice signal (80) that is a function of the first, second and third original voice signals, and generating at least one combined encoded voice signal (90) from the at least one combined voice signal; and a transmitting device for transmitting the at least one combined encoded voice signal to the first, second and third communications units over corresponding outbound wireless communications resources (18, 28, 38).
