Abstract: A tracer-liner portion includes an inner tube and an outer tube, each including at least one wall having an internal surface and an external surface, the walls of the inner tube and the outer tube being impermeable to fluid flow, the outer tube having an internal diameter which is larger than the outer diameter of the inner tube, the inner tube being arranged coaxially within the outer tube such that at least a portion of the external surface of the inner tube is covered by the outer tube; the internal diameter of the outer tube exceeds the outer diameter of the inner tube by an amount sufficient to form a space between the external surface of the inner tube and the internal surface of the outer tube, and a tracer material containing a tracer compound is present in the space.

Abstract: A fuel door assembly for a motor vehicle is provided. The fuel door assembly includes a housing, a fuel door and a door seal. The fuel door is hingedly supported by the housing for rotation between an open position and a closed position. The door seal includes a proximal edge supported by the housing and a distal edge separated from the housing. The door seal has an arcuate shape extending from the proximal edge to the distal edge when the fuel door is in the open position.

Abstract: Techniques are described herein for automatically determining play states, intrinsic motivators, play types/patterns and a play personality of a user/subject. Play personalities develop from activation of play states, and vary individually and are expressed in a variety of play type/patterns. These states, personalities, patterns and associated intrinsic motivations may be automatically determined by computing devices based on that user/subject's information, behaviors and biometric data. The play personality may be additionally used as the means for identifying and integrating intrinsic motivators into player-centric design which can alter and personalize user/subject/player engagement, experience and outcomes.

Abstract: Techniques are described herein for automatically determining a play personality of a user. Play personalities develop from play type and play patterns, which may be automatically determined by computing devices based on that user/subject's information and actions. Furthermore, in a gaming environment, the play personality of the user/subject may be represented by an avatar, doppelganger, narrative, graphic or iconic depiction. The play personality may be determined based on the avatar or doppelganger's actions, which may include but are not limited to how they respond to questions posed by non-playing characters and/or the avatars or doppelgangers of other users. Once determined, the play personality may be used as a basis for identifying and integrating intrinsic motivators and integrating user-centric design which can alter some aspect of the game environment, such as the appearance of the avatar, or the nature of a quest, or means for identifying or exploring solutions in gamification.

Abstract: A rotatable performance device, such as a yo-yo, is modifiable such that the device can act as a relatively responsive device for beginners and a relatively stable device for advanced users. Spacers that facilitate these modifications and a method for configuring the spacers to change the device's responsiveness and stability are also disclosed.

Abstract: A method, system, and computer program product for an environmentally-friendly parking reservation system are provided in the illustrative embodiments. A computer receives a request to make a reservation for parking a vehicle in a parking area. A parking location in the parking area is selected in an application, forming a selection. The computer modifies the selection based on a qualifier in the request, the qualifier indicating an environmentally-friendly aspect of the vehicle. The computer generates a response, the response identifying the parking location.

Abstract: A method, system, and computer program product for parking reservation that encourages car-pooling are provided in the illustrative embodiments. A processor, at a first mobile data processing system representing an automobile, receives an input to create a reservation for a parking location. A second mobile data processing system is detected, wherein the second mobile data processing system is within a threshold distance of the first mobile data processing system. A determination is made whether a movement of the second mobile data processing system relative to the first mobile data processing system is less than a threshold measure of the movement. Responsive to the determining being affirmative, a qualifier is applied to the reservation to obtain a benefit in the reservation, wherein the qualifier accrues a benefit to the reservation.

Abstract: A modification method and system. The method includes retrieving by a computer processor of a computing system a list of features and plug-ins associated with an application. The features include features version metadata and the plug-ins include plug-ins version metadata. The computer processor compares features source code associated with the features with previous versions of associated source code. The computer processor generates modified features version metadata associated with the features version metadata. The modified features version metadata includes updated version labels differing from previous version labels of the previous versions of associated source code. The features are assembled into an application.
