8. The method of forming a reclosable bag of claim 6 wherein said rear seal is a fin seal.
9. The method of forming a reclosable bag of claim 6 wherein first and second interlocking profiles include respective first and second flanges and wherein said steps of sealing said first and second interlocking profiles include sealing said first and second flanges to said front and rear walls thereby forming respective first and second flange seals.
10. The method of forming a reclosable bag of claim 9 wherein side seals meet said first and second flange seals but do not extend to said interlocking profiles.
11. The method of forming a reclosable bag of claim 6 further including the step of loading product into said reclosable bag prior to the step of folding said section of web to form a lower folded edge and a lower rear wall of the reclosable bag.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An apparatus comprising:
at least one storage device to store code to transmit a first protection signal using orthogonal frequency division multiplexing, the first protection signal corresponding to a clear-to-send packet having a source address and a destination address corresponding to the apparatus, then transmit a second protection signal having direct spread modulation prior to transmission of a first data frame from a direct spread-compatible wireless device, wherein the apparatus is an access point, and thereafter wirelessly transmit the first data frame at a 5 Gigahertz band using non-orthogonal frequency division multiplexing, wherein the first protection signal may be received by wireless stations only capable of orthogonal frequency division multiplexing communication, and the data is only received by wireless stations capable of non-orthogonal frequency division multiplexing communication, the second protection signal to enable direct spread transmission of the first data frame from the direct spread-compatible wireless device, wherein the first protection signal is to prevent transmission from the orthogonal frequency division multiplexing-capable wireless stations during the wireless data transmission.
2. The apparatus of claim 1, wherein the first protection signal is to enable the 802.11a wireless stations to update a virtual carrier sense counter network allocation vector.
3. A system comprising:
a flash memory to store code to transmit a first protection signal using orthogonal frequency division multiplexing, the first protection signal corresponding to a clear-to-send packet having a source address and a destination address corresponding to the system, then transmit a second protection signal having direct spread modulation prior to transmission of a first data frame from a direct spread-compatible wireless device, and thereafter wirelessly transmit the first data frame at a 5 Gigahertz band using non-orthogonal frequency division multiplexing, wherein the first protection signal may be received by wireless stations only capable of orthogonal frequency division multiplexing communication, the second protection signal to enable direct spread transmission of the first data frame from the direct spread-compatible wireless device, and the data is only received by wireless stations capable of non-orthogonal frequency division multiplexing communication; and
a wireless interface coupled to the flash memory to transmit the data.
4. The system of claim 3, wherein the system comprises an access point.
5. The system of claim 3, wherein the system comprises a mobile device able to also wirelessly transmit data at the 5 Gigahertz band using orthogonal frequency division multiplexing.
