A portable data storage device includes a USB controller, a master control unit and a NAND flash memory device. The master control unit receives data to be written to logical addresses, and instructions to read data from logical addresses. It uses a memory address mapping table to associate the logical addresses with the physical addresses in the memory device, and writes data to or reads data from the physical address corresponding to the logical address. The mapping is changed at intervals, so that different ones of the physical address regions are associated at different times with the logical addresses. This increases the speed of the device, and also means that no physical addresses are rapidly worn out by being permanently associated with logical addresses to which data is written relatively often.

A windshield wiper system for an automotive vehicle is disclosed in which the windshield wiper washer fluid is heated and delivered to the windshield through the rubber wiping element. In one embodiment, the windshield wiper fluid is heated to a substantial level of temperature and pressure within a sealed reservoir by the heat from the engine coolant system. In another embodiment, a tubular electrical high intensity heating element with turbulent counter flow is used to instantly heat the windshield wiper fluid, and the heating element is automatically electrically energized in response to fluid flow through the tubular heating element. In another embodiment electrical direct current vehicle power or selectively alternating current external power is used to heat fluid to a substantial level of temperature and pressure within a sealed insulated reservoir. A novel windshield wiper blade is also disclosed in which the wiper blade has a longitudinally elongated fluid chamber formed along its length. The fluid chamber is closed at one end and connected to the source of the washer fluid at its other end. A plurality of longitudinally aligned slits is formed through the wiper blade to the outlet edge to uniformly dispense the heated washing fluid downstream of wipe direction, and onto the vehicle windshield while one or more openings are also formed in the wiper blade to direct a portion of the heated washing fluid to the joints in the wiper support frame to remove ice binding the wiper frame flex joints. Additionally, the dual configuration of the blade edge is such that the second edge pair wears out sequentially to the first edge pair effectively doubling the clean wiping life of the blade.

A computer-implemented method and information handling system manage a rate of decreasing full capacity of a rechargeable battery by using a projected / target rate of decreasing charge capacity for the battery. The method includes determining an actual rate of decreasing charge capacity of the battery, comparing the actual rate of decreasing charge capacity to the projected / target rate of decreasing charge capacity to determine whether the actual rate of decreasing charge capacity is greater than the projected rate of decreasing charge capacity, and if the actual rate of decreasing charge capacity is greater than the projected / target rate of decreasing charge capacity, modifying one or more variable parameters to slow down the actual rate of decreasing charge capacity of the battery such that the actual rate of decreasing charge capacity remains within a range of the projected / target rate of decreasing charge capacity, and charging and discharging the battery using the modified parameters.

The crushing and high voltage electrostatic separation process of waste printed circuit board includes first crushing waste printed circuit board into 5-20 mm fragments, then pulverized into 0.06-0.5 mm grains and final separating metal grains from non-metal grains. The pulverized grains are fed to separating roller in high voltage electrostatic separating apparatus homogeneously and bombarded with negative ions the corona electrode generates to be charged. The metal grains are discharged fast in the earthing roller and electrostatically attracted with the static charge the electrostatic electrode generates to separate from the separating roller and fall into the metal collecting area, while the negatively charged non-metal grains are repelled electrically by the electrode to maintain on the surface of the metal roller before being brushed with a brush to fall into the non-metal collecting area. Thus, non-metal grains are separated from the metal grains in low cost, high efficiency and no pollution.

Natural joint interfaces wear out and / or are damaged causing pain and disability. They can be currently replaced by artificial surfaces made of materials or in the near future by magnetic fields. They would benefit from a PVES (paramagnetic visco-viscoelastic supplement) that can replace or augment natural joint interfaces or augment total joint replacements. Joint replacement components can be modular and would benefit from a PVES to decrease wear and damp impact between modular parts of a single component. The PVES is a dynamic interface allowing components to be less rigid. Energy transmission is reduced. PVES can act as an interface between natural damaged joint surfaces obviating the need for classic total joint replacement or between the surfaces of artificial joint components to improve or supplement their function. These PVES can be controlled by magnetic fields with respect to their location, physical properties, loads, etc. PVES are typically made of paramagnetic ions and a substrate molecule. One such PVES can be made of gadolinium ions and hyaluronic acid to form gadolinium hyaluronate.

A device for serving as a wheel for motor vehicles, where the wheel has its tire tread replaceable when it is worn out via unique rims and molded tire features. An alternate internal structure prevents the tire from “going flat” or “blowing out” when it is punctured or cut. In one variation the tire can be used with existing rims and can be retro-fitted into existing tire by mating the tires with this invention's “Non-Flat Tire” internal element and special rim. A variation of the “Non-Flat Tire” system uses spring-like materials for its tire core that is shaped similar to a tire's inner tube, and functions like an “air-filled” tire, but the absence of the use of air in this unique configuration gives it the “Flat Tire Prevention” effect.

The system may include a wear-out module configured to provide a wear-out signal, the wear-out signal indicating a remaining amount of useful life of the component; a health module configured to provide a health signal, the health signal indicating an extent to which operational and environmental factors affect a failure rate of the component during a useful life of the component; and a mission module configured to provide a mission signal, the mission signal indicative of whether an operating condition is approaching a threshold that would adversely affect the system's ability to meet at least one performance objective.

An ultra-thin dielectric film is subject to a dynamic electrical bias. During a first phase, the ultra-thin dielectric film is under a high field bias generated by the application of a high voltage. The duration of the high electrical stress is dependent on the intrinsic properties of the ultra-thin dielectric material. In a second phase, the ultra-thin dielectric film is subjected to an operating field bias generated by the application of an operating voltage. The change in the field bias exposes the dielectric to a similar dynamic stress that microelectronic devices ordinarily experience. At the operating field stage, a gate current is measured and compared to a predetermined range. Once the gate current exceeds that range the test concludes. Otherwise, the test cycles between the above-mentioned phases for a predetermined number of iterations based on prior experimental correlation. In a destructive testing mode, the process is continuous and does not conclude until the gate current exceeds a predetermined range. The ultra-thin dielectric gate current may also be measured as the ultra-thin dielectric is heated so that the transport properties or reliability of the ultra-thin dielectric is more clearly understood.

By screwing the screw by rotating from the slot, the screw will rotate so as to drill a hole and enter into a wood plate. Then the protruding sheets enlarge the hole. The undesired wood pieces are removed from the recesses. When the screw further drills into a metal plate, the protruding sheet will be worn out because the protruding sheet is made of soft metal.

A new method and apparatus signals to an inspector on a cursory exterior examination of a vehicle that brake pads have reached the limit of safe wear. Brake pads are designed to release a material that has a color other than the browns and grays of conventional brake pad dust when they reach the limit of safe wear. The colored material distributes itself on the wheel of the vehicle, thereby offering telltale evidence of worn-out brake pads. A first embodiment brake pad employs a colored powdered material enclosed in at least one pocket beneath the normal wear range of the friction lining. A third embodiment brake pad employs a heat-stable, colored liquid or slurry in metal capsule. The capsule is breached by rubbing against the brake rotor when the wear limit is reached. Inorganic pigments are used for powder, slurry and friction lining colorants.

A high-speed universal motor running at over 10,000 or even over 20,000 rpm includes a non-rubbing water repellent sleeve that protects the bearings from moisture damage. Rather than having a sliding contact seal that can quickly wear out under such high speeds, the sleeve is made of material having a low solid surface energy so that the seal material itself repels waters on its own. TEFLON is the preferred material, which is relatively soft, so to prevent the compressibility of the seal from affecting the axial positioning of parts on the motor shaft, the seal is installed such that the seal does not contribute to the critically precise positioning of the shaft and the parts mounted to it. In some embodiments, for example, the relatively soft seal simply overlies a much stiffer, accurately machined metal spacer.

Disclosed therein is a big femoral head and femoral head surface replacement, which are used for hip osteoarthritis and vascular necrosis of femoral head. As a person get older and aged, the weight bearing hip joint is indispensably changed to osteoarthritis and sometimes showed avascular necrosis of the femoral head with unknown etiology. The deformed femoral head and hip joint should be replaced with the THA. Till now, the total hip replacement is performed in such a way that the necrosed femoral head and a healthy femoral neck are all removed and a femoral stem is inserted into the marrow cavity, and in this case, a small femoral head causes a reduction of a range of motion and dislocation of the hip joint occasionally, and osteolysis due to abrasion of plastic acetabular liner. In case of a conventional femoral head surface replacement (hereinafter, called “conventional FHSR”), a complication of femoral neck fracture and could not combined use with conventional THA. Recently, hard bearing system such as metal on metal THA or ceramic on ceramic THA without using plastic has been introduced to solve the problem of osteolysis due to abraded plastic particles generated when the THA is worn out as time goes. But there also have many problems as a limited range of motion, resected normal femoral neck and difficulties of rereplacement of the femoral stem. Because of the big femoral head or the FHSR can increase the range of motion and lower dislocation rate these devices are gradually widespread in young active person and Asian peoples. This invented design of the modularity gives the convenience to the surgeon and economically lower burden to patients to use of the FHSR and big femoral head system. The related accessory showed initial stability of the FHSR during operation and prevent from femoral neck fracture in follow-up periods.

An apparatus and method are described that allows for the production of vortex-ring bubbles in a host liquid. A simple embodiment of the device consists of an inverted cup with a short nozzle protruding into it through the center of its end face. Circular plates are fixed to both open ends of the nozzle tube, which itself is positioned such that its lower end is at a higher level than the open end of the inverted cup. When cup is immersed in a liquid, open end down, and the inside of the cup is pressurized with an inflow of gas, a confined volume of gas will form inside the cup, and the liquid level in the cup will fall, and peel away from the nozzle lower end plate. The gas is exposed to the open lower end face of the nozzle, but does not enter the nozzle until the pressure has built up within the cup sufficiently to break the surface tension meniscus at the nozzle inlet. The gas then self accelerates up through the nozzle and rapidly exits at the upper end of the nozzle tube. The confined liquid level in the cup rises back up in response and enters the nozzle in a unique self-siphoning action shutting off further gas flow out the nozzle. The exiting gas bubble self organizes into a gas-filled, vortex ring. Alternatively, the exiting flow of gas can be captured in a second conical nozzle and buoyantly directed to the throat of the nozzle where it undergoes the same self acceleration and self siphoning to form a vortex ring at the throat exit. Other different embodiments of the device that all operate under the same method of intermittent breaking of surface tension forces followed by self acceleration and self siphoning to generate a vortex ring bubble are described. The advantages of the device are that it is mechanically simple, easy to manufacture, has no moving parts, will not wear out, and does not require any operator intervention in order to function.

A pedal with a body that has two plates that can be easily removed or displaced to access the inner surfaces of the pedal and the backside of traction pins. In this way, traction pins can be replaced even after the pins have been worn out or broken. Also, the plates can be made out of a harder, more durable, more expensive material than the material of the body, because the plates are typically subjected to the most impact and abrasion because of the shape and location of the plates. Alternatively, the plates can be made of a relatively inexpensive material because the plates are easy to replace if worn or damaged. Also disclosed is a system for re-greasing the inside of the pedal including a screw-in end cap that can be removed, and a slot down the inside of the body that allows grease to flow around a sealed bearing.
