Abstract: An analog neural network circuit includes at least one fewer layers than a number of expected layers of a neural network such that at least two cycles of feeding back outputs and applying weights occur to complete all the expected layers of the neural network. A control circuit, for example implemented using an analog oscillator, provides timing signals to control signal paths, including a feedback signal path to reuse circuitry of a layer for the at least two cycles. An analog memory is coupled to store an output of the circuitry of the layer. The analog memory is controllably coupled as part of the feedback signal path to the circuitry of the layer.

Abstract: A wheel cover mounting assembly is revealed. A cover whose shape is similar to that of an automotive wheel is mounted into an axle hole of the automotive wheel by a mounting assembly. The mounting assembly includes a through hole at the center of the wheel cover and a circular wall arranged in the through hole. A threaded segment formed on an inner surface of the circular wall and a moveable base are threaded and locked with each other. A thread portion engaged with the threaded segment is disposed on surface of the moveable base. Through the design of the relative thread depth of the thread portion with regard to the threaded segment, the moveable base presses the circular wall against the axle hole of the automotive wheel for positioning the circular wall in the axle hole firmly.

Abstract: An adjustable wheel cover for aluminum alloy rims is revealed. A wheel cover is disposed with through holes corresponding to hollow holes of an aluminum alloy rim. A peripheral wall is extended axially from an inner surface of the wheel cover and along a periphery of each through hole. At least one assembly part is formed on the peripheral wall and an insertion slot for receiving a fixing part is arranged at the assembly part axially. The assembly part is disposed with a plurality of adjustment holes radially. A locking block on a spring of the fixing part is secured in the adjustment hole correspondingly. Thus the wheel cover can be adjusted flexibly to fit the aluminum alloy rims with production tolerances. The problem of unstable connection between the wheel cover and the aluminum alloy rim caused by unmatched size can also be solved.

Abstract: A wheel cover has several through holes thereon, and several wall portions encompassing respective ones of the through holes; the encompassing wall portions project from an inner side of the wheel cover and abut respective ones of the edges of the through holes; the encompassing wall portions each have several detained protrusions on an outward side of a tail end thereof; the wheel cover is joined to an aluminum alloy wheel, which has several hollow portions, with the encompassing wall portions thereof being passed through respective ones of the hollow portions, and with the detained protrusions being tightly pressed against inner ends of the hollow portions and detained in the aluminum alloy wheel; thus, the wheel cover is firmly held on the aluminum alloy wheel.

Abstract: A wheel rim cover engagement device includes an engage ring and a steel ring. The engage ring is fixed in the recess of the flange of a wheel rim, and a wheel rim cover has its inner fastening members tightly clasp the engage ring and is fixedly assembled on the wheel rim, able to solve the problem that a wheel rim cover cannot directly be installed on the wheel rim of a large-size car because the radian of the flange of the wheel rim is too large and the inner circumferential edge of the wheel rim is too straight.
