Abstract: An two-way optical communication apparatus, including a transmit element, a receive element, and a transceive processor. The transmit element is coupled to a light pipe, and transmits a first signal. The receive element is coupled to the light pipe, and receives a second signal. The transceive processor directs the transmit element to pause and then resume transmitting the first signal during first intervals, and directs the receive element to sample for the second signal during one or more second intervals within each of the first intervals, where the each of the first intervals is less than a first value and the first intervals occur at a duty cycle no greater than a second value, and where the first and second values are controlled by the transceive processor such that a user perceives the first optical signal as having a constant state for a third interval.

Abstract: An apparatus is provided for commissioning a target device onto a wireless local area network (WLAN). The apparatus includes a smart wireless device. The smart wireless device has commissioning logic and a transducer. The commissioning logic is configured to format and direct transmission of one or more WLAN configuration packets that convey WLAN configuration data. The transducer is coupled to the commissioning logic, and is configured to transmit the one or more WLAN configuration packets over the transmission path to the target device, wherein the transducer is an existing component of the smart wireless device.

Abstract: Methods of using FLASH memory to emulate EEROM are disclosed. The present method uses two pages of FLASH memory, where each page is one or more separately erasable blocks. One page is referred to as the current page, while the other is the next page. Tokens, which are data structures containing a data element, are written in successive locations in the current page. When the current page is nearly completely filled, the write operation starts writing the new tokens to the next page. In some embodiments, to equalize the execution time of the write routine, the write routine also copies one token from the current page to the next page after a new token is written to the next page. Once all tokens have been copied to the next page, the current page can be erased. At this point, the next page becomes the current page.

Abstract: Various techniques for reducing power in a wireless network device are disclosed. In some embodiments, software routines within the device are modified to minimize the time during which the analog circuitry in a radio is powered. In some embodiments, the techniques make use of knowledge of implied delays associated with a particular network protocol. For example, in a CSMA network, there is a defined minimum period before the device can attempt to gain access to the media. The radio may be powered off during this defined period. In other embodiments, modifications to a protocol are disclosed which allow additional power savings.

Abstract: A system and method for prioritizing multiple audio sources and balancing them in a single combined output in a handheld device. Audio sources are sensed and combined with the level of each source subject to adjustment by an attenuator/amplifier. A priority logic unit controls the attenuator/amplifier associated with each source. the level of each source being combined is adjusted on the basis of the character of the sources being combined and a set of programmed rules. For example, if source A is a high priority source (e.g. a telephone ring or other alert tone) and source B is a lower priority source (e.g. a music program) then the sound management system may lower the volume on source B combine with source A and output the result. Alternatively, source A may be raised in volume, combined with source B, and then output. In one embodiment, the sound management system is integrated with a palm sized handheld computer system.

Abstract: An embodiment of the present invention is directed to a method for controlling software in an electronic system having a plurality of applications and an insertable peripheral device. In one embodiment of the present invention, an indication is received from a headphone jack regarding the insertion state of an audio plug. In response to the indication, a software application resident on said electronic system is automatically notified of the insertion state. In response to the notifying, the execution state of the software application is automatically changed. In one example, the application suspends when the plug is removed and automatically resumes when the plug is reinserted.

Abstract: A computer disk sleeve comprised of a semi-rigid envelope-like body, an accordion-folded portion and an adhesive portion for attachment to a computer disk. Upon attachment of the sleeve to the computer disk, the disk and the sleeve comprise an integral package. All elements of the sleeve in conjunction provide amplified areas for printed indica or other notation. Variations in the folding methods of the accordion-folded portion provide dust protection and provide use as a mailing container.
