Abstract: A brake testing device (100) evaluates the condition of a disk (102) having a disk axis (106) and first and second disk surfaces (108, 110). The device (100) has two gauges (112, 124), each having a sensing element (114, 126) for measuring the position of one of the disk surfaces (108, 110) along a line parallel to the disk axis (106). The gauges (112, 124) generate signals corresponding to the measured positions of the disk surfaces (108, 110). The gauges (112, 124) are secured with respect to each other so as to measure along parallel lines, and are positioned by the device (100) to measure the disk surfaces (108, 110) at points equidistant from the disk axis (106). Gauges (218, 230) can be employed which allow testing a disk (202) surrounded by a wheel (208) and a dust shield (206). The device (100) may be part of a system (750) which processes the signals to determine the thickness and the lateral run-out of the disk (102), and which may also compare these values to manufacturer-specified standards.

Abstract: The invention is systems and methods for transferring items with restricted transferability. Initially, the systems and methods wait for a first consumer to make a request to transfer an item after having purchased the item from a provider. The systems and methods then send a request to transfer the item to the provider. This request may indicate inducements to the provider to authorize the transfer. If the transfer information is authorized, teh systems and methods then present information regarding the item to other consumers. This information may be presented as part of a bidding interface or as part of an advertising interface. Once the second consumer submits a winning bid for the item when the information is presented in a bidding interface, or an acceptable offer when the information is presented in an advertising interface, the transfer of the item can then be completed with or without the assistance of an intermediary. When the transfer is completed without the assistance of an intermediary, the first and second consumer may directly transfer the item and payment to each other. When the transfer is completed with the assistance of an intermediary, the first consumer may send the item to the intermediary and the second consumer may send payment to the intermediary.  Once both the item and the payment have been received at the intermediary, the intermediary may send the item to the second consumer and all or part of the payment to the first consumer.
