A sound and light machine (SLM) produces sound and light pulses at brain wave frequencies so as to induce a particular state of consciousness in a user, while simultaneously providing music. The SLM includes light emitting diodes (LEDs) and headphone speakers. A microcontroller runs firmware to control the LEDs and headphone speakers so as to produce a plurality of dominant brainwave frequencies. Binaural voices produce a melody of music without interfering with the brainwave frequencies. Each note of the melody is sounded at a specific pitch based on information in a Tone Object, which includes a state variable index holding the note's current position within a waveform array and a state variable step, which is an amount by which to increment the state variable index at each iteration. The index is set to 0 at startup and the step is calculated from the initial note desired.

A sound and light machine (SLM) produces sound and light that pulses at brain wave frequencies. The SLM is programmed to induce a particular state of consciousness in a user. The SLM includes a left and a right light emitting diode (LED) (). The LEDs () are configured to be placed in front of the user's left and right eyes, respectively, and are programmed to pulse light at a frequency that helps induce the particular state of consciousness in the user. The SLM has a left and a right headphone speaker (). The speakers () are configured to play different tones into right and left ears to produce binaural beats that match the LED pulse frequencies. The SLM also has a microcontroller () on circuit board that runs firmware to control the LEDs and headphone speakers.

The present invention is related to methods and systems for providing different stripe sizes for different zones for at least a first of a plurality of mirrored drives to improve data rates. The first drive has a plurality of zones. In one embodiment, a first stripe size is selected for a first zone, and a second stripe size is selected for a second zone. The said second stripe size is different than said first stripe size.

Methods and systems for mirrored disk arrays

The present invention is related to methods and systems for improving the read performance of a drive array, such as a RAID array, having an &ldquo;n&rdquo; number of drives so that the read performance is greater than (n&minus;1) times that of an independent single drive. Formatting information for each of at least three drives is received. A first parity block size for use with corresponding first zones of the at least three drives is selected. A second parity block size different than the first parity block size is selected for use with corresponding second zones of the at least three drives. The first and the second parity block sizes are selected to increase the read performance from the drive array based on at least a portion of the formatting information.

Methods and systems for selecting block sizes for use with disk arrays

The present invention is related to methods and systems for accessing multimedia data stored on a disk array to ensure that the transfer rate does not fall below a selected minimum transfer rate independent of where the multimedia data is stored on the disk array. In one embodiment, the sizes of blocks accessed are varied and the direction of access is selected to enhance read performance. A plurality of blocks are read whose sizes vary linearly as data is being read from a first disk in a backward direction, from an inner diameter side of the first disk, towards an outer diameter of the first disk. Blocks are read from a second disk in a forward direction, towards an inner diameter of the second disk.

Methods and systems for accessing disks using forward and reverse seeks

The present invention is related to methods and systems for reducing head movements during accesses to drives within a drive array by dynamically selecting which one of a first drive and a second drive is to be used to read data stored within a first logical address range. A first set of data is stored in both the first drive and the second drive. The logical block addresses accessed by at least a portion of read operations are monitored. The first drive is designated as a data source for data stored on both the first drive and the second drive in the first logical address range. The second drive is designated as a data source for data stored on both the first drive and the second drive outside the first logical address range. The designation of drives is performed at least partly in response to the monitoring act.
