Abstract: An exercise bike operable while remaining stationary on a support surface. The exercise bike includes a bicycle frame with a pedal assembly coupled to a clutch mechanism that is movable between an unlocked state in which the pedal assembly drives a wheel in a first rotational direction and rotates relative to the wheel in a second rotational direction, and a locked state in which the pedal assembly is rotationally fixed to the wheel to drive the wheel in the first rotational direction and the second rotational direction, and a handlebar assembly. The handlebar assembly is coupled to the bicycle frame and includes a handlebar and a locking mechanism. The locking mechanism is moveable between an unlocked position in which the handlebar is allowed to rotate about an axis, and a locked position in which the handlebar is restricted from rotating about the axis. A control module may move the locking mechanism and the clutch mechanism between their respective locked and unlocked states.

Abstract: A soft switch 134 providing wireless PBX voice services to a local area network (WLAN) is used to extend PBX functionality to the cellular domain. A dual mode remote unit is capable of receiving signals both in the cellular system as well as the WLAN. The cellular system is comprised of a data-bearing path and a voice-bearing path. When the dual mode remote unit is within the WLAN, it communicates both voice over IP (VoIP) signaling as well as session initiation protocol (SIP) control signaling over the WLAN. When the remote unit is outside the WLAN, it communicates voice signaling over the voice-bearing path of the cellular network using a standard cellular voice channel. In parallel, it uses the data-bearing path of the cellular network to transmit SIP control signaling.
