Abstract:

An air spring actuated brake assembly for a railway vehicle braking system is provided which comprises an air spring disposed between a mounting member for attachment to the rigid structure of the braking system and a push rod attached thereto for longitudinal movement in an outward direction upon actuation thereof to initiate a braking sequence of the railway vehicle braking system. The air spring actuated brake assembly of the present invention allows for improved control of the brake shoe forces including visual travel measurement indication which is especially desirable during light load conditions. Additionally the air spring actuated brake assembly of the invention allows for the visual inspection and simple replacement of an inflatable spring should an air leak in the actuator occur. Currently used brake assemblies employing cylinder type actuators may be retrofitted with the air spring actuator of the invention.

Abstract:

The disclosed technology includes systems and methods for identifying synthetic identities among a population of entity representations in an electronic database. The method includes include selecting a first entity representation, and for the selected first entity representation, identifying one or more network chains formed by one or more connections between the first entity representation, a second entity representation, and zero or more intervening entity representations; and determining a number of connections per connection degree for a predetermined number of degrees in at least one of the identified one or more network chains; determining, based on the number of connections per connection degree, an indication that one or more of the first entity representation, the second entity representation, and zero or more of the intervening entity representations is a synthetic identity; and outputting entity representation information of one or more entities in the population that are indicated as a synthetic identity.
