A system and method of verifying whether a certificate has been revoked by providing a DNS responder containing a certificate revocation list (CRL), parsing the CRL into DNS zones, and distributing this information to the respective primary DNS responders based upon DNS zones. Information about a specific certificate is gathered by querying a DNS responder for certificate validation information, receiving such information, and reporting the results of the queries to a client software application so that the user of the system can be informed as to whether the certificate has been revoked or not.

A method for masking at least one turbine engine component wherein the method includes providing at least one masking member, securing each masking member to the at least one turbine engine component, and applying a metal coating to the at least one turbine engine component.

An input/output (I/O) port designed for electrical interconnection with multiple similar ports includes an input read circuit, an output drive circuit, and a circuit to control the port for input or output mode by electrically disconnecting the output drive circuit from the port. Also included is a back drive current protection circuit placed in series in between an external I/O line and the input read and output drive circuits which blocks backdrive currents from other active processors when the processor that includes the protection circuit is in a powered down state while still allowing full input/output functionality in a powered up state.

Methods and apparatus for full I/O functionality and blocking of backdrive current

A significantly improved scanning method and apparatus is disclosed which allows tone channel guard decode and scan to optimally coexist on the priority channel. In an exemplary embodiment of the present invention, tone channel guard decoding processing is divided into three processing windows. The first window (hereinafter referred to as SHORTLOOK) serves to indicate whether channel guard might be present. If the SHORTLOOK window processing indicates that the correct channel guard might be present, then a further processing window, hereinafter referred to as SECONDLOOK, is initiated. If at anytime during the SECONDLOOK time period, a second predetermined threshold is exceeded, the system is informed that the correct channel guard tone pattern is most probably present. The audio is then unmuted, even though the SECONDLOOK time period expires before the channel guard tone pattern is capable of being reliably detected in accordance with conventional standards. A LASTLOOK window is utilized when the SECONDLOOK window has detected a tone and opens the audio. During the LASTLOOK window, a further tone channel guard detect threshold is monitored. If this threshold is exceeded, then the priority channel audio is allowed to remain active, thereby serving as a check on the determinations made in the SHORTLOOK and SECONDLOOK windows.

Radio communications device incorporating channel guard decode and

An arrangement for establishing communication between a first mobile radio transceiver and a second mobile radio transceiver through a repeater over a radio frequency channel selected from a plurality of such channels. A repeater distinguishes between two-tone signalling sequences and four-tone signalling sequences by determining the arrival rate over some predefined interval of a received signalling sequence. The repeater transmits a busy signal to alert mobile stations seeking to acquire a channel that the repeater is busy. The repeater interrupts the transmitted busy signal during a portion of the four-tone signalling sequence but not the two-tone signalling sequence to help prevent two-tone mobile stations from falsing on four-tone signalling sequences. The arrangement is thus made compatible with both two-tone signalling and four-tone signalling formats. A calling mobile transceiver may specify the length of signalling transmitted by the repeater, so that the mobile transceiver can cause the repeater to transmit signalling for a duration longer than the mobile transceiver itself would require.
