Abstract:
Access to an authentication image may be protected so that only authenticated processes have access to the image. The image can be displayed to authenticate a User Interface (UI) to a computer user. The image indicates the UI can be trusted. If the image is not displayed, it may be that an application UI is “spoofed” to trick a user into providing sensitive information. Additionally, a large variety of different images can be used as authentication images, so spoofing one image be recognized by most users. A set of original images may be provided, along with image modification processes which can generate a large number of variations. Techniques for authenticating UIs in a virtual machine context are provided. A secure attention sequence is also provided, which allows users to test whether processes running on a computer are authenticated.
Abstract:
A system and method for renting or purchasing products, preferably digital media. The system comprises a self-check station and unique locking apparatus for the media. The method includes a procedure to both rent and return the media without the aid of borrowing facility personnel.
Abstract:
An axle assembly includes a shaft supported for rotation within an axle housing. The housing is mountable to a trailing arm pivotal relative to a vehicle. The axle shaft includes a hub mounted on a first end for mounting of a wheel. A rotor is mounted to a second portion of the axle. The second portion of the axle shaft and rotor is mounted at a position inboard of any portion of the wheel rim. Mounting of the rotor outside any portion of the wheel rim allows the rotor, caliper, and actuator to be configured without constraints on size and cooling concerns inherent with brake assemblies positioned within the circumference of the wheel rim.
Abstract:
Techniques are disclosed to provide security for graphical user interface elements being displayed in a system in which a first, host operating system is used along with a second, high assurance operating system, where the first system provides at least some of the infrastructure for the second system. Graphical user interface elements associated with the high-assurance operating system are prevented from being obscured and from any partial transparency. Additionally, a piece of secret information is stored which can be displayed upon command by graphical user interface elements associated with the high-assurance operating system. Coordinating certain elements of the display of all graphical user interface elements associated with the high assurance operating system also helps to identify legitimate elements associated with the high assurance operating system, as opposed to impostor elements which are not. Where a windowing system is used, public title information is furnished to a host operating system windowing system to identify a window owned by a process running on a high-assurance operating system. Private title information associated with the same window is used only in the high assurance operating system.
Abstract:
A brake caliper includes an actuator, a moveable brake pad including a brake pad backplate having a generally planar portion, and a friction material secured to the brake pad backplate. The brake pad backplate is being generally arcuate in shape and defines a friction material outer radius and has a friction face for engagement with a brake disc. The brake pad defines a wear limit of the friction material at a wear limit plane that is parallel to the friction face. The brake pad backplate includes a first pad abutment to limit rotation of the brake pad in a first direction. The first pad abutment is defined on a first lug surface of a first lug projecting from the generally planar portion, and the first lug surface is at a radius larger than the friction material outer radius and is positioned on the friction face side of the wear limit plane. The brake caliper also includes a stationary brake pad and a frame having a housing region for receiving the actuator, a reaction side portion for receiving the stationary brake pad in an axially static manner, and a first bridge arm connecting the housing region to the reaction side portion. The actuator is operable to move the moveable brake pad towards the stationary brake pad. The first pad abutment engages a first bridge abutment on the first bridge arm to limit rotation of the brake pad in the first direction.
Abstract:
A brake and actuator assembly includes a brake housing (4), an actuator device (6) mounted on the housing, the actuator having a force transmission element (7) extending through an opening (8) in the housing and cooperating with an actuating member (10) of the brake within the housing. A seal (12) is arranged to seal around both the opening (8) and element (7) whilst permitting the latter to move in a direction longitudinally of the element for brake actuation. The sealing element has a portion (14A) arranged for sealing engagement with the member (10) at least when that member is in its inoperative rest position.
Abstract:
A method for interacting with a user, comprising communicating with at least one cooperative server through a normal browser; automatically receiving encrypted data having an associated received type code indicative of a requirement for a secure browser having restricted functionality with respect to a functionality of the normal browser; selectively and automatically invoking the secure browser for handling of the received encrypted data based on the received type code associated with the received encrypted data; receiving the encrypted data with the invoked secure browser for handling thereof, wherein the received encrypted data is not available for use by the user in the normal browser and the invoked secure browser imposes restrictions on availability outside of the secure browser of decrypted data derived from the encrypted data; and communicating an input from the user, through the secure browser, to the at least one cooperative server.
Abstract:
An acetabular component (10) for hip surgery has an outer convex surface for location in the acetabulum and an inner concave bearing surface (16) suitable for holding and bearing against a corresponding femoral head component, without need for an interposed liner. The outer convex surface and the inner concave surface define between them an integral wall (14) of the component. Screw holes (18) are provided though the wall, from the inner concave bearing surface to the outer convex surface for screw fixation of the component in the acetabulum.
Abstract:
A disc brake includes an actuation mechanism, and first and second brake pad mounting structures to be located, in use, adjacent opposing inboard and outboard faces, respectively, of a brake rotor to be braked. The disc brake further includes first and second brake pads located by the first and second mounting structures, respectively, such that upon application of the actuation mechanism, the brake pads clamp the brake rotor, and brake torque is reacted by the brake pad mounting structures. The first brake pad has a different functional requirement to the second brake pad such that fitment of the first brake pad in the second brake pad mounting structure and/or the second brake pad in the first brake pad mounting structure impairs the safety, functionality or durability of the brake. To prevent or inhibit such incorrect fitting, the first brake pad includes on a peripheral face or a rear face thereof a first formation in such a location that it may only be successfully fitted in the first brake pad mounting structure and only successfully fitted in the correct orientation with the brake fully assembled. The second brake pad includes a second formation different from the first formation such that it may only be successfully fitted in the second brake pad mounting structure and only successfully fitted in the correct orientation with the brake fully assembled.
