1. An FFT accelerated display mode process comprising the steps of:
streaming time domain samples for a signal into a data buffer representing a measurement frame that provides a desired frequency resolution;
providing a spectrum analysis display from an initial number of time domain samples when received in the data buffer from the streaming step;
updating the spectrum analysis display when a specified number of additional time domain samples have been received in the data buffer from the streaming step;
repeating the updating step until the spectrum analysis display encompasses the measurement frame.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
I claim:
1. A releasably engageable sole assembly for footwear, comprising:
(a) an outer sole including a retaining lip;
(b) a latch movably connected to the outer sole between a capture position and release position, the latch being spaced from the retaining lip;
(c) a bias mechanism connected to the latch to urge the latch into the capture position; and
(d) a release mechanism connected to the latch to selectively move the latch to the release position.
2. The sole assembly of claim 1, further comprising a mid sole having a catch sized to cooperatively engage the latch.
3. The sole assembly of claim 2, where the mid sole includes a tongue sized to cooperatively engage the retaining lip.
4. The sole assembly of claim 1, where the release mechanism has a recessed surface to enable its selectable actuation.
5. The sole assembly of claim 1, further comprising an axially translatable actuator connected to the release mechanism.
6. The sole assembly of claim 1, where the bias mechanism is a spring.
7. A sole assembly, comprising:
(a) an outer sole including a retaining lip;
(b) a locking mechanism spaced from the retaining lip; and
(c) a mid sole having a catch sized to engage the releasable locking mechanism, and a tongue sized to cooperatively engage the retaining lip.
8. The sole assembly of claim 7, where the retaining lip is along a front perimeter of the outer sole.
9. The sole of claim 7, further comprising a spring connected to the locking mechanism.
10. The sole of claim 7, wherein the locking mechanism is exposed to a side edge of the outer sole.
11. The sole of claim 10, wherein the locking mechanism is rotatable.
12. The sole of claim 11, wherein the locking mechanism includes a slotted surface for selectably rotating the locking mechanism.
13. The sole of claim 7, where the outer sole is transparent.
14. A sole assembly including a mid sole and a separable outer sole, one of the mid sole and the outer sole including a fastener and a retaining lip spaced from the fastener, the fastener moveable between a capture position and a release position, wherein the fastener in the capture position and the lip cooperate to preclude separation of the mid sole and the outer sole, and when the fastener is in the release position, the mid sole is separable from the outer sole.
15. The sole assembly of claim 14, further comprising an upper connected to an upper surface of the mid sole.
16. The sole assembly of claim 14, further comprising an upper connected to a lower surface of the mid sole.
17. The sole assembly of claim 14, further comprising an upper connected to an interior surface of the mid sole.
18. An article of footwear, comprising:
(a) a mid sole having a forward ground contacting portion and a spaced apart rearward ground contacting portion;
(b) an arch between the forward ground contacting portion and the rearward ground contacting portion; and
(c) a catch extending beneath the arch from the rearward ground contacting portion to beneath the arch.
19. The article of footwear of claim 18, comprising also an outer sole selected to releasably engage the mid sole.
20. An article of footwear comprising
(a) a mid sole having a forward ground contacting portion and a spaced apart rearward ground contacting portion; and
(b) a lip extending forward from the forward ground contacting portion; the mid sole having an aperture extending thereinto above the rearward ground contacting portion.
21. The article of footwear of claim 20, comprising also an outer sole selected to releasably engage the mid sole.
22. A method for assembling a sole assembly for a shoe, comprising the steps of
(a) engaging a tongue in a mid sole with a lip in an outer sole; and
(b) reversibly fastening the outer sole to the mid sole at a position spaced from the lip.
23. A method for assembling a sole assembly for a shoe, comprising the steps of:
(a) engaging a tongue in a mid sole with a lip in the outer sole; and
(b) contacting a latch connected to the outer side with the mid sole to releasably engage the mid sole and the outer sole.
