A distress signal sender and a distress signal receiver receive beacon-name generation parameters and generate a beacon name based at least in part on the received parameters, the beacon name representing a network location. Responsive to detecting an unexpected lack of access to network communications, the distress signal sender sends a beacon message to the generated beacon name, the beacon message describing a security state of the client. The distress signal receiver detects the beacon message sent by the distress signal sender, and responsive to receiving the beacon message, performs a remedial action.

The disclosure generally relates to systems and methods for allowing a person to activate a distress signal via a portable device, such as a mobile phone, without having to physically look at the portable device. For example, if a victim is being held hostage, attacked, threatened, etc., and cannot use their mobile phone in plain sight of the hostage-takers, the present invention allows the victim to silently activate a distress signal that can be sent to various third-party response providers, such as a 911 dispatch center, a private security/monitoring service and a friends and family network. The distress signal is activated through various software- and/or hardware-based tactile mechanisms and buttons provided on the portable device.

The invention relates to the field of flight devices, and provides a flight vehicle searching device and a searching method thereof. The searching device is arranged on a flight vehicle, and works independent of the flight vehicle. The searching device comprises a controller, and a power supply module, a wireless communication module and a positioning module which are connected with the controller. When the flight vehicle is working or stops working, the controller judges whether or not to send a distress signal to the outside. After judging that there is a need to send a distress signal to the outside, the controller acquires the current location information of the flight vehicle from the positioning module, and sends a distress signal containing the acquired location information to a handheld terminal of a user through the wireless communication module. The handheld terminal determines the location of the flight vehicle according to the location information in the received distress signal. Compared with the prior art, as the searching device is an independent device and can work independently, the searching device is not affected by flight vehicles, the possibility that a flight vehicle is found is improved, and the economic loss of users is reduced.

An insecticide organic fertilizer composition eradicates insects such as imported fire ants (IFA). The insecticide organic fertilizer composition comprises an aqueous homogenized manure extract having an active ingredient, a surfactant, a solvent, and a fatty acid. Active ingredients include botanical insecticides which are subject to degradation after a preselected period of time upon delivery to a soil area. The botanical insecticide is selected from the group consisting of rotenone, pyrethrum, sabadilla (varatrine), neem (azadirachtin), ryania (ryanodine), and mixtures thereof, with rotenone being the preferable botanical insecticide selected. Advantageously, the combination of these components and component amounts renders the botanical insecticide's active ingredients, including rotenone, stable in the aqueous organic manure extract for a predetermined period of time. During this predetermined period of time, the insecticide organic fertilizer composition biologically interferes with IFA's pheromone distress signals. Upon application of the insecticide organic fertilizer composition to an IFA mound, the IFAs began to exhibit a state of sluggishness and gradually begin to die over time rather than relocating, effectuating effective eradication after treatment. In addition, the biotanical insecticide functions to fertilize and nourish soil near the vicinity of the mound.
