Read/write heads for exchanging information with a magnetic media in either vertical or horizontal recording modes include SQUID detectors coupled to the magnetic flux path of the head. Selective use of superconducting material improves the data interchange operating efficiency of the read/write head and its coils. Magnetic paths associated with head elements are confined and directed by superconducting material to produce compact data with minimal power requirements. Magnetic read/write heads containing Josephson junction or SQUID detectors and which are encased in superconductive material allow high density data recording and highly sensitive data detecting. Data density is also improved by selected application of superconductive material to magnetic read/write heads constructed for perpendicular recording.

A pile driver is described wherein a piston within an internal combustion engine is rigidly coupled to the pile to be driven. The engine is resiliently coupled to the pile so as to move with the pile. Control circuitry modifies the frequency of operation of the piston so as to make the impulses created thereby synchronous with reflected impulses within the pile.

Amplification and synchronization of photon pulses in optical computing chips is accomplished by placing parametric amplifying devices at predetermined spatial locations in the light conductive paths that make up the optical circuits in the chip. The laser pumping signal for the parametric amplifiers is clocked by a system clock which also clocks the generation of the data photon pulses in the optical circuits. By synchronizing the arrival of a pumping pulse with the arrival of the photon pulse at a parametric amplifier, the data pulse can be amplified, reshaped and resynchronized. The pumping pulse can be directed to the spatially located parametric amplifiers on the chip in a number of different ways. The chip could be masked except for the parametric amplifiers, and the entire chip could be illuminated by the pumping laser though collimating lens. If the chip is not masked, then pumping light must be directed only to the parametric amplifiers. This could be done with a hologram to spatially distribute the light beams to the amplifiers. Alternatively, the beam from the pumping laser could be piped by light conducting fibers to the parametric amplifiers with light pipes. Further, the light pipes for the pumping pulses could be light conducting channels in a second optical chip, or an additional optical circuit layer.

Superconducting material improves the operating efficiency and reduces the operating power demand for a disk drive suitable for interchanging data with a magnetic or optic media. The arm containing the head is moved along a path by a balanced superconductor to magnetic field interface such as for radial positioning relative to a circular media and is maintained in constant spatial relation with respect to the media by advantageous application of superconductive layers and magnetic field sources. The superconductor environment also permits efficient bearing support for the media as well as accommodating superconductor motors for driving the media and the use of various circuit elements associated with the drive electronics.

A vehicle tire inspection apparatus includes a flat plate, a flexible bladder containing a quantity of fluid, and transducers on the plate. The plate is made of a transparent yieldable resilient bendable material capable of transmitting an inflated vehicle tire footprint and of undergoing a deflection in response to the supported weight on the tire applied thereon. The bladder is supported on the top side of the plate and has an upper opaque portion of a first color, a lower transparent portion and an enclosed interior cavity. The fluid contained within the cavity is of a second color different from the first color of the upper bladder portion. The fluid is displaceable within the bladder as the upper bladder portion is forced toward the lower bladder portion when the tire is applied upon the upper bladder portion so as to create an image of the footprint of the tire viewable on the bottom side of the plate by contrast between the second color of the fluid viewable where a tread of the tire does not press the upper bladder portion against the lower bladder portion on the top side of the plate and the first color of the opaque material of the upper bladder portion viewable where the tread of the tire presses the upper bladder portion against the lower bladder portion on the top side of the plate. The transducers are attached to the bottom side of the plate and undergo deformations proportional to the deflection of the plate and produce electrical signals proportional to the deformations.

Information-bearing signals are stored using high-temperature superconducting materials. Type II semiconductors, such as materials in the perovskite class, are used for recording. A vortex of electrical current is induced in a layer of the super-conductive materials which causing a magnetic field extending from the axis of the vortex. One or more vortices can be used to record one bit of information. The induced magnetic field is sensed for reading the stored information.

A single blade ice skate is disclosed wherein the ice engaging blade, the toe boot plate and the heel boot plate are formed as a unitary assembly from a flat sheet of metal stock material, with the two boot plates being attached to the blade by way of twisted metal extension portions. In the initial flat state, the blade portion, the two extension portions and the two boot plates occupy a common physical plane. The two extension portions that connect the boot plates to the blade are then twisted 90.degree. in this common plane, and in a manner to place the two boot plates in planes that are normal to the plane of the blade and normal to the common plane of the initial metal stock material. The two boot plates are then bent into a U-shape, so as to provide a U-shaped vertical spring member for each of the boot plates, the spring member acting between the two boot plates and the blade (i.e. a spring member operating in the vertical plane of the blade), while at the same time providing a rigid lateral connection between the plane of the two boot plates and the plane of the blade, thereby rigidly maintaining these planes as normal planes during a skating maneuver.
