  • Publication number: 20170169576
    Abstract: The present invention relates to a flow velocity measuring method. The flow velocity measuring method includes providing a video recording a temporal and spatial variation of a flow wherein the video contains multiple frames; selecting multiple sampled frames from the multiple raw frames by a sampling rate and dividing each multiple sampled frames into multiple sub-frames; grouping the multiple sub-frames situated on the same corresponding position on the each multiple sampled frames together to make multiple sub-frame videos; providing each multiple sub-frame videos to different multiple observers, each of which observers marks out a flowing feature for at least one of the multiple sub-frame videos; computing multiple spatial displacements for each multiple flowing features and a time interval between each multiple sampled frames from the sampling rate; and determining a flow velocity of the flow based on all the multiple spatial displacements and the time interval.

  • Patent number: 9549861
    Abstract: An early warning method and a device for preventing a wheelchair from tipping over are described. The early warning method includes projecting a laser light pattern, scanning the laser light pattern, making a comparison to determine whether the ground is a barrier terrain, and issuing an early warning to the user in situations of risk. The laser light pattern is projected onto the ground and compared with a standard pattern. The early warning is generated and is one selected from a group consisting of a beep, a warning message and a vibration to alert the wheelchair user to the danger of the barrier terrain.

  • Publication number: 20150170392
    Abstract: In a method for an electronic device to output handwriting fonts, a thickness and a color is chosen for lines of handwriting fonts. Coordinates of touch points in response to a handwriting operation on the touch screen are recorded and one or more handwriting fonts are generated based on the recorded touch points. A first bitmap including the generated handwriting fonts is generated and a compression ratio between a minimum area of the generated handwriting fonts in the first bitmap and a area of a font in a text box of the electronic device is calculated. The generated handwriting fonts are compressed according to the compression ratio and a second bitmap including the compressed handwriting fonts is generated. The second bitmap is converted into a figure, and the figure is outputted in the text box of the electronic device.

  • Publication number: 20140368638
    Abstract: The present invention provides a method of mobile image identification for flow velocity and the apparatus thereof. The present invention integrates laser-light module and mobile photographing devices such as smartphones, cameras, or tablet computers. After multiple laser spots are projected on the surface of flowing water, water-surface images including the laser spots are photographed continuously. Then the software program of image identification in the mobile photographing device performs calculations and coordinate conversion. According to the difference between multiple water-surface images taken continuously, the flow-velocity information of the water surface is given.

  • Publication number: 20140217447
    Abstract: Phosphor compositions for highly reliable white light-emitting diode (LED) devices are disclosed. The phosphor compositions include a first oxynitride-based phosphor that emits green light and a second nitride-based phosphor that emits red light. When the weight ratio of the first oxynitride-based phosphor to the second nitride-based phosphor is from about 8:2 to 9:1, the emission spectra of the phosphor compositions are very similar to that of a yellow YAG phosphor with a peak at 550 nm. The phosphor compositions have emissions with CIE color coordinates satisfying an equation expressed as: y=0.0805x3?154.06x2+97017x?2E+07.

  • Patent number: 8456288
    Abstract: A communication device locks input of the communication device and executes an alarm if a current time reaches a set alarm time. When the alarm is executed, an unlock input set is generated for unlocking the input and an alarm disable button set is generated for disabling the alarm. If an unlock input set is the same as the generated unlock keypad set, the locked input is unlocking. If the alarm disable button set input by the user is the same as the generated alarm disable button set, the communication device disables the alarm.

  • Patent number: 8088672
    Abstract: A method for producing a thin film includes the following steps: providing a primary substrate; forming an etching stop layer on the primary substrate; forming a sacrificial layer on the etching stop layer; implanting gas ions to form an ion implantation peak layer, which defines an effective transferred layer and a remnant layer; and separating the effective transferred layer from the remnant layer. The thickness of the effective transferred layer can be effectively determined by controlling the thickness of the sacrificial layer. Moreover, the thickness of the effective transferred layer can be uniform and then the effective transferred layer can become a nanoscale thin film.
