  • Publication number: 20150376878
    Abstract: A faucet valve core includes an outer shell, a bottom cover connected with a bottom of the outer shell, a valve stem rotatable and partially mounted in the outer shell. The inner end of the valve stem is connected with a top side of the movable valve plate, a bottom side of the move valve plate is connected with a fixed valve plate. A pair of water channels is conic and is formed through the fixed valve plate and each water channel has a top opening and a bottom opening that is larger than the top opening. Given the faucet valve core, water flow rate can be increased while the size of the entire faucet valve core can be reduced.

  • Patent number: 9189004
    Abstract: A control circuit, control method used in a PFC circuit and the power source system thereof are disclosed herein. The control circuit comprises: a zero current detection circuit having a polarity detection circuit for outputting a first and a second digital signals and a signal conversion circuit for generating an analog signal; a feedback circuit for generating a driving pulse signal; and a pulse distribution circuit for distributing the driving pulse signal to a first and a second switches according to the first and the second digital signal. After a switch cycle, one of the first and the second switch performs an ON operation for the next switch cycle when the current flowing through the inductor decreases to a predetermined threshold value, wherein an ON time of the first switch is equal in each switch cycle, and an ON time of the second switch is equal in each switch cycle.

  • Patent number: 8983185
    Abstract: Disclosed is a method of compressing an image to be stored in a memory to satisfy a memory requirement. A size of a region having a uniform colour in the image is determined. The determined size of the region is compared with the candidate values of the region size threshold. A value is selected from the candidate values as the region size threshold based on the comparison between the estimated data amounts to satisfy the region size threshold and the memory requirement. The edges constituting the region which satisfy the selected value of the region size threshold are compressed losslessly.

  • Publication number: 20150036160
    Abstract: A method for combining layers of an image represented using an intermediate format receives at least two layers from the plurality of layers to be combined and estimates resources required to combine the received layers using a first combining operation. The first combining operation comprises at least rasterising data of the received layers. The method attempts to combine the received layers using a second combining operation to produce an output in the intermediate format. In response, the method generates a combined layer for the image by combining the received layers in accordance with a selected one of the first combining operation (merge & flatten) and the second combining operation (merge). The selected combining operation is based on success of the attempt. Desirably the method is performed within a printer apparatus where limited memory and/or computing resources are available for image rendering which could otherwise limit the rendering of complex pages.
