    摘要: A fraction chip correlation device for a spread spectrum receiver for receiving signals modulated with spread spectrum codes and a method for operating fractional chip correlation to spread spectrum signals received by the spread spectrum receiver are disclosed. In the present invention, at least one delayed version of an input signal is generated to be correlated with a local code replica to accomplish fractional chip correlation. By doing so, correlators can operate at a low speed, so that power consumption of the receiver can be significantly reduced.

    摘要: The invention discloses an optical recording medium comprising a first substrate, a second substrate, a median layer and an adhesive layer. A plurality of Braille characters is formed on the second substrate by injection molding. The median layer is formed on the first substrate. The second substrate is adhered to the median layer by the adhesive layer. Accordingly, a visually-impaired person can easily identify the contents in the optical recording medium by touching the Braille characters on the second substrate.

    摘要: A satellite signal adjustable time-division multiplexing receiver for GNSS and a method for acquiring and tracking satellite signal used in the receiver. The present invention executes correlation in an adjustable time-division multiplexing and uses a clock signal with a clock rate to control speed of correlation. The clock rate can be fixed or variable. In the case that the clock rate is variable, when the speed is required to be fast (e.g. in satellite acquisition mode), the clock rate is set to be high clock rate; when the speed needs not be so fast (e.g. in signal tracking mode), the clock rate can be lower down to reduce power consumption. The adjustable time-division multiplexing is arranged for respective domains such as visible satellite, code phase, Doppler frequency and tracking accuracy according to the clock rate.

    摘要: A helmet includes a helmet body, and a cooling fan device mounted in the helmet body to introduce an ambient air into the helmet body. The cooling fan device includes a support base, a cooling fan, a battery, and a control switch. Thus, the cooling fan is operated to introduce the ambient air through the vent hole of the helmet body into the helmet body to provide ventilating and radiating effects to a user wearing the helmet body so as to provide a comfortable sensation to the user.
