Abstract: A portable electronic device with a stowable assembly. The stowable assembly may be stowed substantially within the housing of the portable electronic device. In the presently preferred embodiment, the stowable assembly has a display and a hide-away keyboard having at least one key.

Abstract: Methods for controlling data rate allocations to data packet users transmitting packet data over a CDMA cellular communication network are defined which comprises the steps of: evaluating traffic channels and radio capacity allocated for packet data services within the network to determine an available resource for a packet data transmission; employing a rate control algorithm to determine a data rate allocation for the packet data transmission; and limiting the transmit power of a transmitter to provide the determined data rate allocation for the packet data transmission. The methods include a rate control algorithm which determines data rate allocation using a transmission power budget technique and a rate control algorithm which determines data rate allocation using a current system load technique.

Abstract: A product and method for preventing a connector from rotating when a mating connector is attached to, or detached from, the connector. When a nut on the connector is tightened, a washer is compressed in a groove in a panel to which the connector is attached. Edges on the outer perimeter of the washer press against the edges of the groove, thus preventing the washer from rotating in relation to the panel having the connector. A portion of the washer's cutout presses against flat regions on the connector and, in conjunction with the groove in the panel, prevent the connector from rotating when attaching or detaching cables.

Abstract: Innovative systems and methods for advantageous use of a new isolated power converter topology, in which transformer isolation is provided by a very simple DC-DC converter operated in open-loop mode (with each switch running at a constant duty cycle of approximately 50%, to achieve an effective duty cycle of approximately 100%), and feedback or modulation is instead applied to a preconverter stage which also does power factor corrections. Since the isolation stage is operated at a constant duty cycle, distortion can be minimized and its efficiency can be fully optimized, with a simple circuit and small component count. Unlike a flyback converter, only a very small inductance is required. A simple control architecture is used with current control loop. The disclosed circuit tightly clamps the voltages on the switch and on the transformer, with no ringing nor overshoot.
