  • Publication number: 20170115500
    Abstract: This disclosure provides a laser speckle-removing optical component, including a beam-shrinking lens group and a diffusion sheet arranged on a laser emergent optical path, where the beam-shrinking lens group includes a first beam-shrinking lens and a second beam-shrinking lens, and the diffusion sheet is located between the first beam-shrinking lens and the second beam-shrinking lens. The arrangement of the diffusion sheet between the first beam-shrinking lens and the second beam-shrinking lens, increases the area of speckles received by the diffusion sheet component, reduces energy density of the light received, and is able to alleviate the accumulation phenomenon of dust particles on the diffusion sheet, therefore, alleviating light attenuation phenomenon, and prolonging the service life of the laser source. This disclosure also provides a double-color laser source, a three-color laser source and a laser projection equipment applying the above laser speckle-removing optical component.

  • Publication number: 20170048346
    Abstract: A method for pushing data in a Content-Centric Networking (CCN) network comprises receiving a message from a source at an input interface device of a node device in the CCN network, the node device executing a CCN protocol. A determination is made that the received message is an interest-notification message. The received message is identified as the interest-notification message by including a Type field, a Content Name field, and a Cacheable Object field. The Type field indicates that the received message is pushing data within the CCN network. The Content Name field associates a hierarchical name to the data being pushed within the CCN network. The Cacheable Object field includes a cacheable object representing the data being pushed within the CCN network. The cacheable object is extracted in response to the received message being an interest-notification message. The cacheable object is placed in a cache at the node device.

  • Publication number: 20170023750
    Abstract: An N×N parallel optical transceiver includes a printed circuit board, a laser driving control chip, one or more lasers, two GRIN lenses, an optical band-pass filter, a multimode fiber array and a photodiode array. In the transmitter, laser beams of the same wavelength simultaneously output from the laser chip are first focused by the first GRIN lens, then the beams pass through a wavelength band-pass filter and are refocused by the second GRIN lens, and enter the channels in the multimode fiber array. In the receiver, laser beams of a different wavelength from the multimode fiber array are focused by the second GRIN lens, then reflected by the band-pass filter, refocused by the second GRIN lens, and received by the photodiode array. The multi-channel parallel transceiver has a small form, and can integrate a DFB or FP laser chip and GRIN lenses.

  • Patent number: 9550476
    Abstract: An overload protection in a drive unit for a steady or jack for a caravan comprises an electro-mechanical control system. A spindle is driven by a motor through a gearbox, wherein the motor is controlled through a power supply. A control device in the system comprises a movable part slidably seated on an output shaft of the gearbox, where the movable part is connected with the spindle. Movement between the shaft and the sliding part is counteracted by springs. The slidable part is provided with actuating points that may contact switches by axial movements. When a nut on the spindle reaches an end position, a reactive force in the spindle will cause the part to move against the force of springs, eventually actuating a switch and thereby causing interruption of the circuit, thereby protecting motor and engagement between nut and spindle from electric and mechanical overload.
