Abstract: A lubrication structure for a shock absorber of vehicle has a protecting pipe and a self-lubricating layer. The protecting pipe is a non-circular metal tube and has an elongated slit. The self-lubricating layer is an engineering plastic layer, is deposited in the protecting pipe and has a shaft hole. When the lubrication structure is deposited between an outer tube and an inner tube of a shock absorber of vehicle, the protecting pipe engages in the outer tube to prevent the self-lubricating layer from contacting the outer tube directly. The self-lubricating layer with small friction coefficient is mounted around the inner shaft to enable the inner shaft to move smoothly relative to the outer tube. The lubrication structure has characteristics of low cost, small volume, and small tolerance, and the life and the practicality of the lubrication structure can be improved.

Abstract: The digital air pressure gauge includes an error correction lookup table database stored within a memory device within the gauge. The database includes reference air pressure values and associated measured air pressure values, where the reference air pressure values and associated measured air pressure values are determined at identical discrete time intervals as pressurized air is input into the gauge. A transducer generates an electrical signal representative of air pressure within a device such as a pneumatic tire. A microprocessor compares the electrical signal with measured air pressure values within the database and determines a closest measured air pressure value. The microprocessor then determines the associated reference air pressure value of the closest measured air pressure value. The reference air pressure value is then displayed as the accurate pressure of the pressurized air within the device. The gauge may be disposed within a tire valve cap with an RF transmitter.
