The present invention provides a drone-passing multiple detection sensor gate comprising: a gate having a ring-like structure through which a drone can pass during flight; a first sensor, disposed on the front or the inner front of the gate, for detecting whether the drone approaches the gate or passes through the front side of the gate; a second sensor, disposed on the inner rear of the gate, for detecting whether the drone sensed by the first sensor passes through the rear side of the gate; a detection signal transmitter, disposed inside or on a surface of the gate, for receiving, from the first sensor and the second sensor, the detection signal indicating whether the drone approaches or passes through the gate, and wirelessly transmitting the detection signal. In addition, the present invention provides a drone game system using a multiple detection sensor gate.

A publicly accessible urban beach entertainment complex is disclosed, with a man-made tropical, pristine-clear lagoon as the centerpiece of the complex, with surrounding entertainment, educational, sports, and commercial facilities, the complex having controlled public access and providing the look and feel of a tropical beach with clear waters and sandy beaches. In addition a method for efficiently utilizing facilities and land that are vacant, underutilized, have limited uses, or that are contiguous to or nearby recreational, educational, sports, or commercial venues is disclosed. The method providing a publicly accessible urban beach entertainment complex with a centerpiece man-made tropical-style pristine-clear lagoon. The method allows for generating revenue and increasing efficiency by pairing vacant sites, underutilized sites, limited use land, or sites that are contiguous to entertainment, educational, sports, and/or commercial venues with urban beach entertainment complexes. The complex preferably has a controlled public access, thereby allowing entrance upon payment of a fee.

An artificial cave has various features that resemble speleothems (e.g., stalactites, stalagmites, etc.) found in real subterranean caves. Human users may pass through the artificial cave, with each user wearing a wearable transceiver that broadcasts a signal code unique to that user. Fixed transceivers throughout the cave can detect and identify any user who is sufficiently close to that fixed transceiver. Other components of the system collect user identification information from the fixed transceivers for any of several possible purposes (e.g., identifying which user was probably responsible for inappropriate interaction with a speleothem that is adjacent to a given fixed transceiver, where all of the various user of the cave are currently located in the cave, etc.). A count of users currently in the artificial cave passageway may be maintained and used for a number of purposes. Similarly, human detectors may be employed near the system and/or in the artificial cave passage for any of several different purposes.

To provide a pace setting system that can be constructed using only simple equipment at a low price, that has a high degree of freedom in terms of the installation location and applicable competition, and that can be used casually. A pace setting system that presents, to an athlete 2, pace information pertaining to speed, wherein the system comprises: a plurality of smartphones 1a-1n having a communication function and an information output function; and a coordination control unit 11c that controls, via the communication function of each of the plurality of information processing terminals, the timing at which information is outputted from the information output function of each of the information processing terminals. The coordination control unit 11c, which can accommodate a plurality of athletes, outputs pace information that corresponds to a speed setting for each of the athletes, the pace information being outputted at a timing corresponding to each moving body.

A publicly accessible urban beach entertainment complex is disclosed, with a man-made tropical, pristine-clear lagoon as the centerpiece of the complex. The lagoon includes a surf feature and surrounding the lagoon are entertainment, educational, sports, and commercial facilities. The complex has a controlled public access and provides the look and feel of a tropical beach with clear waters and sandy beaches.

A tunnel for mounting above a road surface (3) comprises a plurality of tunnel segments (1). Each tunnel segment is adapted for mounting at least one projector (6) therein, above a respective opening formed by the tunnel segment in a ceiling of the tunnel. The openings (5) of the plurality of tunnel segments are spaced apart in succession in a direction of travel of vehicles in the tunnel. The tunnel segments are disposed such that projection surfaces (8) of the projectors are seamlessly contiguous or overlapping on the road surface in the direction of travel. The tunnel may comprise awnings positioned at its entrance and its exit, the ceiling being formed at least in part by the awnings. A first awning (10A) may be mounted to a first tunnel segment, in the direction of travel, and a second awning (10B) may be mounted to a last tunnel segment, in the direction of travel.

A venue transformation and construction method is disclosed that creates a tropical style swimming lagoon at an infield site of a race or activity circuit facility, the infield site being contained within a race or activity circuit perimeter. The transformation includes demolishing at least part of the infield site; excavating material from an area within the infield site; and forming a basin for a large water body having a surface area of at least 3,000 m2. Water containment walls are constructed on a first section and a sloped access area is formed on a second section of the basin for a beach. A barrier is included to control access to the beach. At least one additional recreational facility is constructed around the basin and a connection is provided that connects the outfield of the race or activity circuit with the infield site to allow transit of vehicles and/or people.
