Abstract: An environmentally friendly weight block for diver's weight belt is disclosed to include a weight formed of a lead block made in the shape of an English letter and coated with a layer of anti-corrosion plastic coating, and a clip or belt loop affixed to the back side of the weight for fastening to a diver's weight belt.

Abstract: The present invention provides a protocol structure to accelerate memory transmission, characterized in that an address memory unit is built in the front end of the memory, of which comprises several address buffers, and there is a pointing design between each address buffer and the corresponding data block in the memory. Address data is saved in address buffers in advance by external pins to further quickly match such address data with the corresponding data block without entering long data address every time. The invention provides the industry users the method to rapidly change the data address for data transmission and access.

Abstract: An IC oscillation frequency internal drive control characterized by that a record unit being provided at the front end of the oscillator of the IC circuit; the record unit including multiple recordable points and a safe recordable point; the front end of the record unit being connected in series with an internal record control circuit to receive signals inputted from an external circuit or software; oscillation frequency being outputted from the rear end of the oscillator to control the internal record control circuit by external signals thus to designate various recordable points to drive and control the oscillator to generate various oscillation frequencies to be transmitted back to the external circuit or software for performing in time self feedback in cycles to detect recording of the optimal drive oscillation recordable points, finally to achieve easy control of safe and constant outputs of working frequencies that are applicable to various electronic peripherals.

Abstract: The present invention relates to an apparatus for automatically selecting an internal or external resistor, characterized by that a built-in control unit is placed in the front of the oscillator of the integrated circuit, and such control unit comprises a detection circuit for coupling the external resistor and oscillator, and an internal resistor bridging the detection circuit in parallel with its output end such that the detection circuit can automatically detect whether or not there is any input of serial signal from the external resistor to switch into the external or internal resistor at appropriate time, and further select inputting the optimal operating frequency of the control IC.

Abstract: The present invention is a method and apparatus for showing special characters or figures on a rotating disk. A sensor (e.g. spectrum sensor, metal sensor, magnetic field sensor, mechanical contact sensor and sound sensor) and a plurality of light fittings (e.g. bulbs, light-emitting diodes) are fitted to the rotating disk. The sensor detects the surroundings with inconsistency so that different sensed signals at different points are created when the sensor turns around the central axis once. By deciding the fixing points of the repetitive signals, the rotational cycle of the rotating disk is obtained. After analyzing the rotational cycle, different light fittings on the rotating disk light up at different delay time point. In cooperation with the persistency of vision of human eyes, the preset complicate figures and characters are therefore shown on the displaying surface of the rotating disk when it rotates.
