Abstract: A minimum frequency generator of a transceiver system is presented. In a transmitter presented with K bits of parallel data, if a flip condition is determined and selected ones of the K bits are flipped, then the flip condition is signaled in a separately transmitted clock signal. The flip condition can be that all K bits are one or zero. Additionally, the clock signal can indicated whether bits are flipped or not by adjusting the duty cycle of the clock signal.

Abstract: A computer system includes a mobile electronic device (30) which can be coupled to a network (18) either directly or through a receiving station (32) such as a docking station or a port replicator. A splitter module (36) is coupled to network connectors (14a and 14b) on both the mobile electronic device (30) and on the receiving station (32) to communicate with either network connector (14a or 14b).

Abstract: This is a locking system for a computing device. The system may comprise: a processor connected to a system bus; an input connected to the processor by the system bus; an output connected to the processor by the system bus; and a module that inserts into the computing device and is connected to the system bus; and a locking mechanism that locks and releases the module to and from the computing device. The locking mechanism may include: a primary lever which engages the module; a manual button which moves the primary lever and disengages the primary lever from the module; a pin that moves from a blocking position in front of the manual button to a non-blocking position clear of the manual button; and a solenoid that controls movement of the pin. Other devices, systems and methods are also disclosed.

Abstract: A notebook computer (10) includes provides power to a parallel port floppy drive (24) through the parallel port connector (48). The computer (10) includes a power switching circuit (30) which detects whether a printer or floppy drive is connected to the parallel port connector (48). If a floppy drive (24) is connected, the power is enabled through the parallel port connector (48). If a printer is connected, power is disabled through the parallel port connector (48).

Abstract: Disclosed herein is a portable computer docking station having a base with an electrical connector and a rotatable member. The base houses various electrical devices such as a battery power supply and memory storage devices. The rotatable member folds between a first extended position and a second extended position about an axis parallel to the base, for respectively receiving and locking the base with a portable computer. When the base locks with the portable computer, the electrical connector of the base connects with the portable computer for interconnecting the electrical devices housed in the base with the portable computer. The rotatable member includes a pair of audio speakers.
