A computer implemented method provides a way of storing custom access control rules with information to which they apply. The rules can be associated with individual pieces of information, to provide a finer grained level of access without the need for prior knowledge of all potential entities that may access the information. The stored data and access control rules may be associated with a virtual representation of an entity, which may be one of many virtual representations of different entities managed within a globally accessible and federated information store. The access control rules can be based on querying information associated with the virtual representation of a requesting party, or information accessible by navigating relationships associated with that virtual representation, thereby providing great flexibility.

An infinitely variable transmission, in which the driver and driven members can exchange their roles—with the driver becoming the driven, and vice versa. The initially chosen driver carries within it a number of movable parts, which the driving forces bring into contact with the driven member, in a manner designed to produce a momentary lock between the driver and driven members, at the point of the torque transfer between them. In one embodiment the driven member—which can be a flat disc—is clamped between two oppositely placed drivers. Infinite variability is achieved by controllably relocating the fixed diameter drivers to smaller or larger diameter points on the so clamped disc. The output can be harvested from the rotation of said driven disc directly. Or one or more driver members like these which are used to rotate said disc, can be brought into contact with different locations on said disc, and become driven by it. In such a case a number of different speeds, or torque levels, can be taken simultaneously as outputs from a single rpm/torque input. In embodiments with a single driver of convex shape input, the preferred driven member is a cone with a concave curvature, to allow for a larger contact zone than two opposing convex parts could provide. Either the flat clamped disc version, or the cone versions, can be stacked vertically or horizontally, with cones nested within each other, to multiply gear ratios and or torques as wished.

A fishing rod securing device includes a housing where the housing has a first end for securing the fishing rod to a structure and a second end for coupling to a fishing rod. The first end has a passage at which the structure can be received. Also, the housing provides a biased element where the biased element detachably clamps the structure in the structure passage.

A level of trust is determined based on a combination of scores for one or more successful authentications. Scores indicate relative degrees of reliability for authentications, so that differing authentication methods may correspond to different scores. The determined level of trust can then be used to allow or deny access to a resource, and can be used to specify the type of access that is allowed, if applicable.

A coupling device is provided for receiving and securing a ball, the ball being attached to the structure to be coupled, including a tow vehicle in the case of a trailer hitch application. Various embodiments of the device for both tongue and “goose neck” trailer hitch applications are included, which provide for simple and effective latching and unlatching, including operation from the perimeter of the vehicle. Hands free latching is provided for all coupling embodiments. A pivoting ball support with one or more recessed faces is rotated and displaced as the ball enters the device, and is returned to a position whereby the ball is prevented from exiting the device. Various provisions are made for retaining the pivoting ball support in this position after such latching has occurred. Provisions for unlatching include various handles and hand pushed structure. Vertical adaptations are provided for use on gates and the like.
