An apparatus includes a base, a body coupled to the base and having slopped sidewalls, and imprinted glass marbles carried by the body. Each imprinted glass marble is configured to transmit terahertz frequencies from 300 GHz to 3 THz. The slopped sidewalls direct the transmitted terahertz frequencies above the body.

The repellent system includes a repellent device, a control device, a message device, and a power device. The repellent device is one for repelling or trapping animals or insects. The control device includes a processing module, a driver module, and a wireless communication module. The driver module is connected to the repellent device and is data-linked with the processing module. The wireless communication module is data-linked with the processing module. The message device communicating with the wireless communication module. The power device electrically connected to the processing module. A user, via the message device such as a cellular phone, obtains status data from the repellent device through the control device, and controls, configures, and adjusts the function and operation of the repellent device in a wireless and two-way interactive manner so that the convenience and applicability of the repellent device is greatly enhanced.

A method of autonomously preventing fouling of a submerged vessel, the method comprising: activating, by one or more computing devices, a at least one transducer and at least one sensor at a first area; generating, by one or more computing devices, a predetermined sound wave from the at least one transducer; monitoring, by one or more computing devices, data collected by the at least one sensor; altering, by one or more computing devices, the at least one transducer, wherein the alteration is based on the data collected by the at least one sensor; and autonomously adjusting, by one or more computing devices, at least one of the at least one transducer, wherein at least one of the transducers is activated.

A behavior modification device includes processing circuitry configured to: acquire sensing information of a sensor to observe a monitoring area; identify behavior of an organism to be threatened present in the monitoring area on a basis of the acquired sensing information; determine a parameter of a stimulus to be given to the organism on a basis of the identified behavior; and generate stimulus data for generating the stimulus on a basis of the determined parameter and output the stimulus data to an actuator for generating a stimulus.

Lighting fixture data hubs and systems and methods for use. An example of a data hub may include an annunciator configured to generate a first indication and a second indication, one or more sensors configured to detect between one or more vehicles and one or more pedestrians and potential convergence thereof within a zone in a vicinity of the data hub and to emit one or more signals corresponding to said detection, and a gateway in communication with an on-board processor and the annunciator, the on-board processor configured to wirelessly receive and analyze the one or more signals, communicate said one or more signals to the gateway so that the gateway can generate the first indication or the second indication in response to the one or more signals. Data hubs may also include a sensor unit housing and/or a light source.

Disclosed is an apparatus for repelling birds that can be readily installed on a structure and effective in repelling birds. To fundamentally prevent the birds from perching on the structure, the apparatus for repelling birds in accordance with an embodiment of the present invention includes: a fastening means including a first supporting part, a second supporting part and a fastening part interposed between the first supporting part and the second supporting part, and having the first supporting part and the second supporting part protruded in a same direction from either end of the fastening part in such a way that a protruded structure is fitted therein; a stopper being engaged with one of the first supporting part and the second supporting part in such a way that the fastening means is fastened to the structure after the fastening means is fitted on the structure, the stopper being at least one bolt; a supporting means being installed on the fastening means; a wire having at least one end coupled to the supporting means; and a tension adjusting means being installed at a portion where the wire is coupled with the supporting means.

A bird deterrent assembly for preventing a bird from defecating on a vehicle mirror includes a pair of clamps that may grip a mirror. A sensing unit is coupled between the clamps to detect when a bird has landed thereupon when the clamps are coupled to the mirror. The sensing unit disturbs the bird thereby preventing the bird from defecating on the mirror.
