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.

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.

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.

A retaining formation defined on a brake lever of an air disc brake includes a push fit/snap fit connection for releasably securing a push rod to a brake lever. The retaining formation can include a pinned connection and a ball and socket joint, and a main axis of the pinned connection is coincident with a center of rotation of the ball and socket joint. The retaining formation can include a concave formation on one of the push rod and the brake lever and a corresponding convex formation on the other of the push rod and the brake lever. The concave formation at least partially surrounds the convex formation to prevent axial separation of the push rod and the brake lever. A method of assembling a brake subassembly includes the steps of assembling a push rod and a brake lever including a retaining formation such that at least a portion of the retaining formation deforms during assembly and resiles when the push rod is assembled to the brake lever to provide a snap fit connection therebetween. Another method of manufacturing a retaining formation includes the steps of providing one of a push rod and a brake lever with a concave formation, providing the other of the push rod and the brake lever with a convex formation able to receive the concave formation, assembling the concave formation and the convex formation, mechanically working the one of the push rod and the brake lever with the concave formation such that the concave formation at least partially surrounds the convex formation to prevent axial separation of the push rod and the brake lever.

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.

An actuating lever of a brake caliper of a vehicle includes a cam surface operable against a single tappet and reacting against a caliper bridge. The actuating lever includes a wear adjuster arm which exerts a turning moment on the actuating lever. The turning moment is resisted by a small stub axle pivotable in a plain bearing of the brake caliper.

An automated technique for switching operating systems, responsive to current context of an executing test scenario. A test designer specifies, in a process control file, a required operating system for appropriate command blocks. A test sequencer packages the required operating system name with each command to be executed, and sends that information to a test listener on a system under test. The test listener remembers the currently-running operating system, and compares that to the required operating system for each command to be executed. If a mismatch occurs, then the correct operating system is not running, and the listener automatically triggers a reboot.

Apparatus and method is provided for using low cost, passive RF sensor technology such as RFID tags, to determine whether containers or other objects are in a right-side-up orientation. A useful embodiment of the invention is directed to sensor apparatus for use in detecting an improper orientation of a conventional box or container with respect to a substantially horizontal surface. The apparatus includes a structure having two sides formed of plastic in spaced apart relationship, to define an enclosed space within the structure. Selected shielding material attached to the structure shields a specified region of the enclosed space against RF signals, the shielded region being located in the lowest portion of the enclosed space when the structure is in a reference orientation with respect to the horizontal surface. An RFID tag embedded in a disk is positioned in the enclosed space, the disk being sized to move freely within the space. A guide element guides the disk in moving between the shielded region and an unshielded region, when the structure is correspondingly moved between its reference orientation and an improper orientation corresponding to an improper orientation of the container. This allows a signal to be received from the RFID tag when it becomes unshielded, to indicate improper container orientation.

A trailer axle assembly includes a non-rotating axle tube that extends laterally between a pair of wheel ends. Each wheel end supports a disc brake assembly that selectively generates a braking force to slow or stop rotation of the wheel ends. The disc brake assemblies include a torque plate that is mounted to the axle tube. The axle tube includes a radial location feature that holds the torque plate fixed relative to the axle tube so that rotational brake torque is transmitted directly through a solid interface. The axle tube also includes an axial location feature that positions the torque plate at a predetermined location along the axle beam and prevents relative axial movement between the axle beam and the torque plate.
