  • Publication number: 20190187003
    Abstract: A temperature sensor probe having a shaft is described. The shaft is made from a material that is corrosion resistant to plasma and remnants of a plasma process. The shaft extends over a portion of a metal layer, which forms a tip of the temperature sensor probe. The shaft further extends over a sleeve of the temperature sensor probe, a portion of a fiber optic medium of the temperature sensor probe and a portion of the fiber bundle housing of the temperature sensor probe. The material of the shaft increases a number of active processing hours for which the shaft is used within a plasma chamber during the plasma process.

  • Patent number: 9628993
    Abstract: A first request is sent from a station to an access point. The station receives a first response from the access point that includes a first sequence number, and stores the first sequence number. The station sends a second request to the access point and sets a waiting period for receiving a response from the access point. The station receives a second response from the access point and a third response from a second access point during the waiting period. The second response includes a second sequence number and the third response includes a third sequence number. The station determines that the second response is a legitimate response by comparing the second and third sequence numbers to the first sequence number.

  • Publication number: 20150358347
    Abstract: Systems, methods, and machine-readable and executable instructions are provided for preventing an input/output blocking attack to a wireless access point. Prevention can include instructions to receive a first comeback request from a querying station and to transmit a first portion of a response in a first comeback response frame including an indication of a comeback delay. Prevention can include instructions to receive a second comeback request from the querying station and transmit a second portion of the response in a second comeback response frame in response to the second comeback request complying with the comeback delay. Prevention can include instructions to drop the second comeback request from the querying station in response to the second comeback request not complying with the comeback delay.
