摘要： A method for bi-directional link margin establishment includes sending a first link margin exchange packet by a wireless end point (WEP) to a wireless access point (WAP); measuring an uplink signal strength of the first packet; sending to the WEP a second packet comprising the measured uplink signal strength of the first packet; measuring a downlink signal strength of the second packet; calculating an uplink link margin based on the uplink signal strength from the second packet; sending to the WAP a third packet comprising the measured downlink signal strength of the second packet and the calculated uplink link margin; measuring the uplink signal strength of the third packet; calculating a downlink link margin based on the downlink signal strength from the third packet; and sending to the WEP a fourth packet comprising the measured uplink signal strength of the third packet and the calculated downlink link margin.

摘要： A method for frequency agility in a wireless embedded system, the wireless embedded system comprising a WAP and a WEP communicating on a current channel, includes determining a first channel table comprising an order of available channels for the WAP; determining a second channel table for WEP, wherein the first channel table and the second channel table list the available channels in the same order; in the event interference is detected by the WAP on the current channel, determining a new current channel by testing the available channels for interference in the order listed in the first channel table; and in the event the WEP does not receive an acknowledgement from the WAP of a message sent by the WEP to the WAP, resending the message on each of the available channels in the order listed in the second channel table until an acknowledgement is received from the WAP.

摘要： A video content analysis (VCA) system generates an output regarding a detected condition that provides an indication of a confidence level regarding the detected condition. One example VCA system determines whether a first characteristic of a detected object in a field of vision of the video content analysis system satisfies a first criterion. If so, a first signal is generated under selected conditions. The VCA system also determines whether a second characteristic of the detected object satisfies a corresponding second criterion. If so, a second, different signal is generated if the first and second criteria are satisfied. The first and second signals indicate respective, different confidence levels that an event has occurred. A disclosed example includes a VCA as part of a security system.

摘要： A system and method for monitoring a location having at least one sensor for sensing a change in at least one condition using voice tags to announce alarms. The system includes a registration process where a voice recorder and a digital conversion unit form digital voice tags from recorded speech representing the type and location of sensors. The voice tag is sent as part of an alarm message or pre-stored in a control panel for later retrieval such that the type and location of an alarm is reproduced vocally at the time of the alarm. The registration process may be completed with a registration module which may be a keypad or the voice recorder may be included in the sensors. Additional features include sensor location change notification to ensure the stored voice tag represents the current location of the sensor.
