A working platform that can be removably attached to a front portion of a utility tractor is provided in which the platform is at least horizontally adjustable, is sized to allow a user to move about on the platform, and the tractor can be controlled by a user with controls located on the platform. In addition, an automatic steering system may be included that allows the tractor to remain generally along a preselected course, such as between rows of trees or other objects. As the tractor moves down the row of an orchard, the platform can be adjusted so as to be in an appropriate position for performing work on the tree.

A fanning plate for a baked potato provides an arched top surface to fan out the slices of a Hasselback potato during the seasoning and baking process, allowing the potato slices to crisp properly, as well as raised rims and endcaps to keep the seasonings contained and prevent a mess. Multiple plates may be easily stacked for compact storage.

A body for a disc brake caliper has a mounting side limb and a non-mounting side limb, each limb housing at least one hydraulic brake cylinder. The body has a peripheral stiffening band that extends about an outer lateral surface of at least one of the limbs. In a preferred embodiment, a peripheral stiffening band extends about an outer lateral surface of each of the limbs. The stiffening band or bands provide stiffness in the body under dynamic braking conditions with a minimum of material. A method of designing and manufacturing a body for a disc brake caliper involves analyzing the stiffness of the body under dynamic rather than static braking conditions and producing a caliper body with a desired level of stiffness under dynamic conditions while reducing the amount of material used to a minimum.

To protect computer programs against security attacks that attempt to corrupt pointers within the address space of the program, the value of a pointer is encrypted each time the pointer is initialized or modified, and then the value is decrypted before use, i.e., each time the pointer is read. Preferably, the encrypting and decrypting steps are effected by instructions generated by a compiler during compilation of the program. One convenient method of implementing the encrypting and decrypting steps is by XOR'ing the pointer with a predetermined encryption key value, which could be specially selected or selected at random.

This invention is a system, an apparatus and a method for measuring biomechanical properties of cornea and the intraocular pressure in vivo. More than one dimensional topographic information of the cornea is recorded and analyzed before and during the fluid discharge and converted to the stress-strain relationship and other cornea parameters, for example the cornea thickness and radius of curvature, etc. The deformation of cornea is initiated by a non-contact fluid discharge whose profile is predetermined and monitored in real time. Utilizing this non-contact topographer, the true intraocular pressure can be derived from the response of the cornea due to the impact of fluid discharge and the corneal topographic parameters. One embodiment of this invention includes the use of a multiple color strobe light/multiple detector system to record the corneal topographic deformation due to the impact of fluid discharge.

In one embodiment, a breathable, incrementally stretched elastic composite material comprises an inner elastomeric film extrusion-laminated to an outer nonwoven web at each film surface. The inner elastomeric film has a random pattern of incremental stretch-formed macroholes therein and is substantially free of pore-forming filler. In another embodiment, a breathable, incrementally stretched elastic composite material comprises an elastomeric film extrusion-laminated to a nonwoven web at one or both of the film surfaces. The elastomeric film has a random pattern of incremental stretch-formed macroholes therein and is substantially free of pore-forming filler. Methods of manufacturing the composite materials comprise extrusion laminating and incremental stretching. Garments and disposable articles are formed at least in part from the composite material.

A probe card assemblage for simultaneously testing one or more integrated circuit chips including an interposer having on one surface a plurality of protruding contact elements for electrically contacting one or more chips of a wafer positioned atop a layer of compliant material, and arrayed in a pattern corresponding to a chip pads, a series of conductive vias through the electrically insulating interposer which connect the chip contact elements with an arrangement of leads terminating in a universal arrangement of connectors on the second surface, and a probe card with connectors mating to those on the interposer. The connectors on the interposer is secured are secured to those on the probe card, thereby providing a vertical probe assemblage which makes use of ultrasonic energy to minimize scrub or over travel. The universal probe card is specific to a tester configuration and common to a family of circuits to be tested.
