A high-profile air sleep system having a pair of air posturizing sleep surfaces which may be individually inclined and air adjusted comprises an air posturing module having an outer module mattress case. The predriver circuit has an input terminal for receiving an input signal, a first terminal coupled to a power supply voltage terminal, a second terminal, and an output terminal coupled to the control electrode of the transistor. The body of the accessory adapter connects to the BTE using the same earhook attachment mechanism used by other accessories used by the CI system. A thread-specific current acquisition cost value is maintained that represents the consumption of computational resources by the thread after the initial attempt to acquire the mutex and prior to acquiring the mutex. The components on the body portions include posts, ribs, and bridges for relieving strain on the electrical wire in the assembly, and other ribs and interlocking components prevent the electrical connector assembly from allowing the wires, the electrical connector device, andor the third body portion from being removed from the folded and assembled electrical connector assembly. The first pusher plate is fitted with an injection screw and supported on a base by a position adjustment mechanism.
