  • Publication number: 20190181797
    Abstract: The present invention provides a smart power supply system including an open storage chamber, a rail, and photovoltaic umbrellas each including a plurality of photovoltaic umbrella panels. The photovoltaic umbrellas may be stored in the storage chamber; the storage chamber is connected to the rail via an opening. When in use, the photovoltaic umbrellas are moved upward from the storage chamber to the rail, then photovoltaic umbrella panels of the photovoltaic umbrellas are expanded. During storage, the photovoltaic umbrella panels of the photovoltaic umbrellas are collapsed, then the photovoltaic umbrellas move downwards along the rail and are then stored in the storage chamber. In the present invention, when use of the photovoltaic umbrellas is required, the photovoltaic umbrellas are expanded outdoor; under certain circumstances such as raining and typhoon, the photovoltaic umbrellas are stored indoor to prevent damages caused to the photovoltaic umbrellas.

  • Patent number: 10020311
    Abstract: A semiconductor memory device is provided such as a random-access memory (DRAM) including a plurality of DRAM memory cells. Each of the DRAM cells includes an N-type transistor, a P-type transistor, and a common capacitor. The components are disposed in the same direction as the bit-line, with the common capacitor occupying the center region between the N- and P-type transistors. The common capacitor is a metal insulator metal (MIM) capacitor configured by connecting three capacitor elements in parallel. The three capacitors include a first capacitor element formed on a first source/drain region of the N-type transistor, a second capacitor element formed on a first source/drain region of the P-type transistor, and a third element over the field isolation region between the transistors. A bottom electrode of each of these capacitor elements connects the first source/drain region of the N-type transistor to a first source/drain region of the P-type transistor.

  • Patent number: 9942956
    Abstract: Embodiments of the invention improve efficiency and address the stability issues that arise when a boost converter is used for both backlight WLEDs and camera flash applications, which require increased voltage or output voltage less than input voltage. In prior solutions, boost converters may suffer poor efficiency when operating in a fixed high output voltage mode or may lose stability by not properly regulating their output when operating in a step-down voltage mode. To improve efficiency of the boost converter, the present invention uses a 100%-pass mode topology when the battery voltage is high enough to support the diode voltage required for the backlight WLEDs or the camera flash. On the other hand, when the battery voltage drops below the required voltage, then the converter switches automatically to boost mode to generate a sufficient output voltage to drive the diodes to the required current level.

  • Patent number: 8996338
    Abstract: A method of detecting a concentration of a target component by using a reference wavelength includes: defining a wavelength at which a light intensity is insensitive to the variation of the target component concentration as a reference wavelength for the target component; detecting spectra at both the reference wavelength and a further measuring wavelength; processing the spectrum detected at the further measuring wavelength, with the spectrum detected at the reference wavelength as an inner reference, to obtain a characteristic spectrum including specific information of the target component; building a calibration model between the characteristic spectrum and the concentration of the target component; and determining the concentration of the target component based on the calibration model.

  • Publication number: 20110193539
    Abstract: A switching regulator generally includes an output circuit, a comparator, an on-time timer and an error amplifier. The output circuit receives an input voltage and produces an output voltage. The comparator causes the output circuit to turn on the output voltage when a feedback voltage falls below a first reference voltage. The on-time timer causes the output circuit to turn off the output voltage after a time-out period. The error amplifier receives the feedback voltage and a second reference voltage and produces the first reference voltage.

  • Patent number: 7533399
    Abstract: An EPG contents collection and recommendation system includes an EPG database of identifications of available programs. A program information acquisition module applies text classification to detailed descriptions of the available programs. An EPG recommendation module recommends an available program to a user based on the text classification. Preferably, EPG contents are collected from publicly available TV websites and parsed into a uniform format. For example, contents are vectorized, and a Maximum Entropy technique is applied. Also, user interaction with the EPG database is used to form a user profile database. Further, classifiers are trained based on contents of the user profile database, and these classifiers are used to recommend EPG contents to the user.
