Abstract: A method for determining false alarms at an entry to an enclosure includes: receiving a first reading from a first sensor representing intrusion of the enclosure, receiving a second reading from a second sensor, and generating an entry alarm if the second reading confirms intrusion of the enclosure. An apparatus that determines false alarms at an entry to an enclosure includes a first sensor which senses for intrusion of the enclosure, a second sensor, and a processor with instructions for generating an alarm if the first sensor detects intrusion of the enclosure and the second reading confirms intrusion of the enclosure. Another method for determining false alarms includes receiving readings from a sensor over a period of time, storing the readings at least temporarily in a memory, and comparing a window of the stored readings to a stored signature. An entry alarm is generated based on a comparison of the stored readings to the stored signature.

Abstract: A method of controlling the simultaneous broadcast of enciphered digital information signals, for example in a radio or television broadcast environment, to a plurality of subscribers provides several levels of enciphering keys. The broadcast digital information signal is in a broadcast common service enciphering key and communication between the transmitter and subscribers may take place in a box key or in a group enciphering key common to a group of subscribers having a common interest in the reception of broadcast signals of a particular type. Each receiver will decipher the broadcast digital information in a specific service key which is common to that broadcast. The service key may be changed at one or more subscribers by communicating the change in the service key to the subscribers by means of the group enciphering key. Further, the group enciphering key may be changed at one or more subscribers or new groups may be formed among subscribers by communicating to the subscribers in one or more group enciphering keys.

Abstract: A system for enciphering information bearing RF signals in digital form utilizes a first key common to all receivers. There are means to change the first key which means include, at the transmitter, means to send individual messages to each receiver, each message being itself enciphered in a second key which is peculiar to only one receiver or small group of receivers and which message includes a change of the first enciphering key. At each receiver there are means responsive to the correct address in a key change message which will thereafter permit the deciphering of the key change message in the key peculiar to the particular receiver or small group of receivers. The new first key is then used at the receiver to decipher subsequent information bearing messages.
