Abstract: An integrated input device communicates with a host computer system in accordance with the low-speed Universal Serial Bus (USB) Specification. The keyboard includes a function controller for providing output signals to a host computer or an upstream hub using a single USB low-speed cable and a USB type A connector. Signals generated by a pointing device are coupled to the appropriate pins of the function controller. The pointing device may be hard-wired to the function controller. Alternatively, the signals generated by the pointing device may be coupled to the function controller using a wireless technique, such as a radio frequency technique or an infrared technique.

Abstract: A power regulator is provided which employs a resonant circuit and permits regulation between a certain maximum value and zero. A series resonant circuit is adjusted to regulate power by adjusting the correspondence between the resonance frequency and the frequency of the voltage source such as an AC source delivering a sine wave or a square wave. Further, the output voltage is regulated to be lower than the voltage of the AC source when output current is zero. A capacitance is connected in parallel with the output of the power regulator to form a second resonant circuit with the inductance of the series resonant circuit. A method of power regulation is also contemplated.

Abstract: A stator assembly for an axial-flow fan motor for cooling electronic components consisting of a base, a stator, and insulating pins for connecting the base to the stator. The stator consists of a core covered by an insulating coating and a winding formed thereon from magnet wire. The stator also includes mounting holes formed in the core. The winding is electrically connected to the base through free ends of the magnet wire forming the winding. Each insulating pin has a first conductive end which is mounted to the base and a second non-conductive end which is received in one of the mounting holes on the stator. In the preferred embodiment, the base consists of a printed circuit board which includes circuitry for operating the motor within which the stator assembly is mounted. The method of securing the stator to the base is also disclosed.
