Abstract:
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.).

Abstract:
Various embodiments facilitate location-aware distributed competitions. In one embodiment, a system facilitates a distributed sporting event that includes multiple players traveling over non-uniform courses that are remote from one another. The system includes a manager that receives state information, such as location information, from client devices used by each of the players. The manager then transmits location information for each of the players to the client devices, which are each configured to present a graphical representation, such as a map annotated with the locations of each of the players. The system corrects for disparities between the non-uniform courses traveled by the players, for example by mapping a location on a course traveled by a first player to a location on a course traveled by a second player. Various mechanisms for establishing the mapping between non-uniform courses are also described.
Abstract:
A masquerading detection system includes: an imaging unit (2) that obtains a first image by imaging an inspection object (12) from a first angle, and a second image by imaging the inspection object from a second angle which is different from the first angle; a unit (101) that detects first feature points from the first image, obtains first feature point coordinates of the detected feature points, detects second feature points from the second image, and obtains second feature point coordinates of the detected feature points; a unit (104) that obtains transformed coordinates by performing a plane projective transformation for the second feature point coordinates from the second image to the first image; and a unit (105) that determines that masquerading has been attempted when the difference between the transformed coordinates and the corresponding first feature point coordinates is equal to or smaller than a predetermined value.

Abstract:
Indicia for providing a visual clue of the position of a vehicle on a race track preferably includes at least one of a first wall indicia strip and a first shoulder indicia strip being formed around the entire race track. At least one of a second wall indicia strip and a second shoulder indicia strip are formed starting at the beginning of the second turn and ending at the start/finish line. At least one of a third wall indicia strip and a third shoulder indicia strip are formed starting at substantially the half way point of the second straight and ending at the start finish line. At least one of a fourth wall indicia strip and a fourth shoulder indicia strap are formed starting at the beginning of the fourth turn and ending at the stop/finish line.
Abstract:
This invention relates to gravity-driven car racing, specifically an improved ramp, such as used in the popular Pinewood Derby race, which is cycloid shaped. The present invention eliminates excessive centripetal force and related problems such as car oscillation caused by prior art ramps which are curved too much or curved in the wrong places. The present invention comprises a ramp shaped as a section of a cycloid curve with the ramp bottom tangent to the horizontal coasting run. It can be shown mathematically that such a curve will produce the least possible centripetal force and associated friction increase in the car wheels as it accelerates toward the coasting run. The present invention causes a ramp to assume the cycloid shape by applying appropriate bending forces to the underside of the ramp. In a preferred embodiment, a hinged brace automatically applies the key bending force as the main support legs are lowered.
Abstract:
The present invention provides a race track configured to encourage passing. The race track includes a pavement that defines a turn, a first path around the turn, and a second path around the turn. The second path is longer than the first path, and the two paths are spaced-apart such that a first car can travel on the first path and a second car can travel on the second path in an overlapped position relative to the first car. At least a portion of the first path passing over a plurality of depressions defined in the pavement at predetermined positions. The depressions configured to reduce the amount of friction available to the first car such that the first car is slowed sufficiently for the second car to maintain the overlap position or pass the first car through the turn as the second car travels on the longer second path.
Abstract:
Disclosed are systems and methods for providing a real-time interactive surface. In one embodiment, such a system comprises an activity surface for use as a venue for an interactive experience, and an interactive experience control unit including an events management application. The events management application is configured to monitor and coordinate events occurring during the interactive experience. The system also comprises a surface rendering application interactively linked to the events management application, the surface rendering application configured to render a visual image for display at the activity surface in real-time, the visual image corresponding to one or more visual assets associated with a subset of the events occurring during the interactive experience. The system further comprises a surface display module interactively linked to the surface rendering application, the surface display module configured to display the rendered real-time visual image at the activity surface to provide the real-time interactive surface.
