A job site security system contains a wireless communications node and a device such as a tool, a battery, a charger, etc., which contains a controller. Each tool has a locked state and an unlocked state as determined by the controller. Each tool is (initially) in the locked state. When the wireless communications node transmits a signal to the device the controller changes the locked state to the unlocked state allowing the device to be used. A method for securing a job site is also provided.

A client device is configured to communicate with an access point over a wireless network, exchanging data with the access point over a selected communication channel. The client device stores an identifier of the selected communication channel. After the wireless connection to the access point has ended, the client device initiates a process to reconnect to the access point over the selected communication channel using the stored identifier.

Techniques for detecting a high gas pressure situation within a gas delivery system (e.g., for natural gas delivery to homes and businesses) are described. In one example, a device measures gas pressure. If a pressure over a threshold value is detected, a nearby device is messaged. The nearby device either confirms the over-pressure condition or indicates it may be more localized. If the condition is present within an area of the gas delivery system and/or within a group of devices within the gas delivery system, protective measures may be taken, such as closing valves providing gas to a number of service sites.

The invention includes systems, methods, and software applications for centrally maintaining information and automatically distributing relevant portions of the information to remote users. In one embodiment, a central server stores the information, which is maintained on the central server. Periodically, or each time the server information is updated, the server identifies the portion of the information that is relevant to each user and downloads the relevant portion of information to each user, for example to a mobile device such as a Blackberry™. The invention may be used to maintain and timely distribute information related to emergency response procedures, sales or servicing schedules, and delivery schedules, among other things.

A criminal act detection system may include a device processor; and a non-transitory computer readable medium including instructions executable by the device processor to perform the following steps: receiving data from a plurality of geographically distributed personal electronic devices; determining, based on the data received from the personal electronic devices, that conduct consistent with a criminal act has occurred; and sending information pertaining to the conduct consistent with a criminal act to one or more of the personal electronic devices.

An information providing system 100 of the present invention includes an acquisition means 121 for acquiring disaster information and acquiring user information that is information related to a user, a generation means 122 for, on the basis of the disaster information and the user information, generating provided information including a captured image that is an image obtained by capturing a predetermined place, and a providing means 123 for providing an information processing device of the user with the provided information.

A server includes a server communication unit, a server control unit, and a server storage unit, and is connected in a communicable manner to a first vehicle and a second vehicle via the server communication unit. The server control unit transmits an imaging start command to the second vehicle, which runs within a predetermined range from an accident site, in response to the reception of an accident notification associated with positional information on the accident site from the first vehicle, receives an imaged image from the second vehicle, and stores the imaged image into the server storage unit.

A network node obtains (302) a message to be transmitted as a public warning system notification to multiple UEs, via one or more SIBs, and obtains (304) area information corresponding to the message. The area information indicates an area for which the message is relevant. The network node determines (306) how many SIBs are needed for transmitting the area information and segments (308) the message into a plurality of segments, based on how many SIBs are needed for transmitting the area information. The network node transmits (310) the message and the area information via SIBs, such that a segment of the message is included in each SIB and such that each portion of the area information included in a SIB is accompanied by a segment of the message. A UE receives the SIBs and assembles the message and area information, displaying the message if it is relevant.

A portable alarm system has a base unit including a processor electrically connected to a wireless transceiver configured to communicate wireless signals to an external location. The base unit is further configured to receive wireless alarm signals from at least a first sensor and a second sensor, both of the first and second sensors being physically separated from the base unit. The processor is configured to be selectively programmed by a user to cause the base unit to communicate with a remote monitoring station in response to receiving an alarm signal from the first sensor, but not in response to receiving an alarm signal from the second sensor. Instead, when an alarm signal is received from the second sensor, the processor causes a different action, other than communicating with the monitoring station, to occur. Such action can include, for example, sending a wireless communication to a mobile electronic device.
