Abstract: A portable computer is provided with retractable ear phones. The ear phones can include ear buds with an outer cushion. The ear buds are retractably coupled with the portable computer by an audio cable. A retraction mechanism retracts the audio cable and ear buds into the computer. The portable computer has a cut out sized to receive the ear buds therein, which creates a place to store the ear buds during periods of non-use. To use the ear buds, a user removes the buds from the storage position, and pulls the audio cable from the computer. Pulling the audio cable activates the ear buds and disables an audio output device on the portable computer. To return the ear buds to a storage position, a retraction actuator is depressed which retracts the audio cable into the portable computer. Alternatively, the ear buds can be replaced or used in addition to an audio input device. The ear buds and/or audio input device can be provided on other devices, such as a portable keyboard.

Abstract: A light conductor and restore spring assembly is made of molded light translucent material which exhibits a significant degree of deflectability and the further ability to rebound or restore to its original shape when released. The framework of the spring forms a light conductor. If the light path needs to be deviated from a straight path the framework of the spring may have reflective surfaces formed into the body of the assembly to reflect the light rays from the input end to the diffusing end of the light path. The external surfaces of the spring/light conductor assembly constrain the light loss by reflecting the light back into the assembly and redirecting it along its path and toward the reflective surfaces or the diffusing end of the light pipe.

Abstract: A computer system having a monitor, disk drive, and central controller is disclosed. The computer manufacturer uses a method for expanding the reserve area of a disk drive to allow computer systems manufacturers to change the storage capacity of the reserve area. The method includes setting up a password with the disk drive manufacturer to enable two commands. One command reads the maximum address or largest track number that the user has access to. The second command allows for setting a new maximum address to which the user has access. The firmware of the disc drive is updated with the new maximum address. Once the two commands have been used to expand the reserve area, the computer system manufacturer can add critical data, and critical program instructions to the expanded or new reserve area.

Abstract: A lightning detection system implemented via a modem or a soundcard is described. The modem is either internally or externally coupled to a communication or computer device. The modem uses one of the unused wires present in the four wire telephone cord that plugs into the modem as an antenna. A digital signal processor (DSP) internal to the modem is configured to function as an AM detector wherein the received signals are processed for determination of a potentially damaging lightning storm. The modem generates an interrupt request based upon the results of the DSP. The interrupt request notifies the communication or computer device which in turn is programmed via a software application to notify the user, such as displaying a warning message on a display device or in initiating a power down sequence.

Abstract: A cooling apparatus is provided in an electronic device, where the cooling apparatus operates on waste heat provided by a heat producing component, such as a computer processor. The cooling apparatus has at least one chamber which is thermally coupled with the processor such that heat from the processor expands the gas within the chamber. The expansion causes movement to a movable piston disposed within the chamber which rotates a crankshaft and fans coupled therewith. The expanded gas is cooled in another portion of the chamber or in another chamber. The cooled gas decreases in volume causing a piston to move, further rotating the crankshaft. The cycle begins again as the momentum of the crankshaft assists in reciprocating the piston or pistons and as additional heat from the processor is drawn into the chamber. The rotational movement of the crankshaft can be used to drive fans thereby cooling the electronic device.

Surrounding the opening in the other electrode is an annular generally conical surface designed to act like a ramp and lead the end of the needle toward the dome-shaped electrode to cause completion of the electrical circuit.

Abstract: A humidifier is provided of the type which has a water tank or reservoir for holding tap water. Common tap water frequently is "hard" due to dissolved minerals which result in the humidifier emitting a fine dust when such water is used. By affixing electroplated electrodes to the interior of the tank minerals such as calcium carbonate can precipitate on the surface of the cathodes. Temporarily reversing the polarity of the electrodes will cause the calcium carbonate to be dislodged from the electrodes and fall to the bottom of the reservoir where it can be removed.

Abstract: Triple-buffering video memory in a computer graphics controller improves the quality of full-motion video converted for display on a computer monitor. Buffer size, organization, and access cycles prevent converted data representing a new video frame from overwriting a buffer in memory that contains converted data representing a video frame currently being displayed. The access cycles also ensure all data representing a video frame is displayed. The video memory is partitioned into three logical buffers to hold the converted data, the buffers are arranged in a logical ring sequence for read and write access, and the data in a buffer is repeatedly read until the next buffer in the sequence is full of data and ready to be read. In addition, the buffering is adaptable to different resolutions as the size of the buffers is determined by the value of the resolution each time the video conversion is initiated.
