  • Patent number: 9449497
    Abstract: An alarm system monitors a home, business, or other property for fire, burglary, break-in, or other event that may warrant raising an alarm. The alarm system is configured to detect tampering, whereby someone intentionally impedes the ability of the system to raise an alarm or otherwise interferes the system's operation. An alarm panel of the alarm system communicates with a server. At certain times, the alarm system transmits a series of packets to the server using a unidirectional protocol. Upon receipt of one of the packets, the server alternates between monitoring for an incoming packet and ignoring any incoming packets. Detection of an incoming packet during a monitoring time period causes the server to transition to ignoring packets for a sleep period of time. Completion of the sleep period of time causes the server to return to monitoring for the monitoring period of time.

  • Patent number: 8723672
    Abstract: A plurality of hazard alarm devices are in spatially diverse locations and coupled together with an input-output bus. An interconnect protocol enables non-originating alarm devices to synchronize their audible alert tone pulses with audible alert tone pulses from an originating alarm device in a local hazard alarm condition. Hence, all audible alert tone pulses start sounding substantially together with allowances for signal contention and arbitration between the spatially diverse alarm devices. The originating alarm device continuously sounds its pattern of audible alert tone pulse groups without interruption, while the non-originating alarm devices periodically pause sounding a group of their audible alert tone pulses. The originating alarm device may be found by listening for the alarm device that is continuously sounding audible alert tone pulse groups without pause.

    Abstract: A method for controlling a water supply amount and a refrigerator using the same are disclosed. The method includes receiving information regarding a water supply amount selected by a user, counting a duration after starting water supply, and checking whether an error in a water supply amount measurement unit exists. When the water supply amount measurement unit is normal, an actual water supply amount is determined based on a signal from the water supply amount measurement unit, and, when a fault exists, a water supply amount is determined based on correlation between a stored water supply amount for normal operation and a water supply duration.

  • Patent number: 8581737
    Abstract: A security system comprises a system control panel for arming and disarming the security system. A door sensing unit comprises a first radio frequency (RF) transceiver interconnected with the system control panel over a network. The first RF transceiver is mounted proximate to a door that defines at least a portion of a perimeter around an area to be monitored by the security system. The first RF transceiver has an RF detection field proximate to the door. A disarm device comprises a second RF transceiver that automatically transmits a disarm device packet. The first RF transceiver receives the disarm device packet when the second RF transceiver is within the RF detection field. The first RF transceiver sends a disarm message to the system control panel over the network to disarm the security system based on at least the disarm device packet.

  • Patent number: 8436725
    Abstract: System which is constituted by one or more positioning devices (2), one or more localizers (1), one or several communication networks and one or several control centers (3). The localizers (1) and the positioning devices (2) have two or more communication interfaces and two or more positioning systems. The positioning devices (2) can calculate the position through some of the positioning systems and send their position via one of the communication interfaces, avoiding inoperability if one of the positioning systems or one of the communication interfaces fails to work. The localizers can perform the function of nodes (4) and forward the data of the position of a positioning devices and make them reach the localizer which has requested that information. Both the positioning devices and the localizers are mobile units. The control centers can monitor the position of the positioning devices if necessary.

  • Patent number: 8378806
    Abstract: A pseudo non-addressable alarm system that uses addressable notification appliances and/or detectors is disclosed. In one aspect, the addressable notification appliances and/or detectors may be entirely automatically (or partially automatically) grouped. One manner of automatic grouping is to use the wiring of the pseudo non-addressable system in order to automatically form the groupings of notification applications, such as grouping the notification appliances based on the signal line circuit to which they are connected. In another aspect, labels for the notification appliances and/or detectors in the pseudo non-addressable system may be entirely automatically (or partially automatically) generated. The labels may be automatically generated based on wiring of the pseudo non-addressable system and/or based on grouping information (such as grouping based on the particular signal line circuit to which the notification appliance is connected).

  • Patent number: 8363790
    Abstract: A method and apparatus for providing automated processing of a switched voice alarm on a switched and/or Internet Protocol (IP) network are disclosed. For example, the method receives an alarm associated with a switched voice service, and retrieves a Local Routing Number (LRN) or Primary Inter-exchange Carrier (PIC) information from a switch serving a call associated with a caller's telephone number. The method determines if the alarm is due to one or more service degradations, and notifies a work center responsible for one or more of the service degradations if the alarm is due to the one or more service degradations.

  • Patent number: 8289146
    Abstract: A monitoring system for a NAC (Notification Appliance Circuit) is provided. The monitoring system includes a system controller, and a NAC comprised of one or more notification appliances that may be in a series. The NAC and its appliances may be operatively coupled to the system controller. The system controller is operable to determine whether a notification appliance has sufficient voltage at a low voltage operation. The system controller may control the voltage to the NAC in order to provide power to simulate operation of the NAC using battery power. A voltage may be measured during the simulation (such as at one end of the NAC). The measured voltage may be compared with a predetermined minimum operating voltage for the notification appliance. Based on the comparison, it may be determined whether the one or more appliances on the NAC may operate properly when the NAC is operated using battery power.
