  • Alternative direct sequence spread spectrum symbol to chip mappings and methods for generating the same
    Patent number: 7903720
    Abstract: Alternative direct sequence spread spectrum symbol to chip mappings and methods for generating the same for use in a direct sequence spread spectrum wireless protocol and embedded in a transceiver chip used by wireless subsystems are provided. The present invention discloses alternative symbol to chip mappings that are orthogonal or nearly orthogonal to the N/2 unused chip sequences defined by a standard transmission protocol. The present invention is advantageous because it provides for an increased number of users and better reliability for wireless subsystems operating in increasingly overcrowded frequency bands. Other advantages of the present invention include a reduction in the negative effects of clear channel assessment including delayed or cancelled signal transmission and interference for wireless subsystems that transmit time-sensitive data.

  • Anti-slipping attachment for shoes
    Patent number: 4302890
    Abstract: An anti-slipping attachment for shoes is disclosed in two embodiments, one for both the sole and heel and the other for the sole alone. The sole portion of each embodiment includes a pair of overlapped plates pivotted together at their rear ends permitting adjustment of the width of the device at its front end. One plate includes an integral tab bent over the other plate to serve as a guide and the other plate includes an integral stop which cooperates with the tab to limit the maximum angular displacement of the plates. The plates, which have integral teeth and integral apertured ears for receiving a strap, are each formed by bending from identical sheet metal blanks.
