  • Patent number: 11688224
    Abstract: The invention provides a vending machine for dispensing hot packaged food. The vending machine includes a storage and dispenser unit comprising plural dispensing trays arranged in an array for storing one or more packaged foods, a frame, and a carrier structure. Each individual dispensing tray includes a pivotable gate and a slideway inclined by a tilting angle from a horizontal axis. The carrier structure comprises a carrying arm having an engaging feature; and an engaging mechanism for actuating the pivotable gate. The engaging mechanism is configured to move the carrying arm towards the individual dispensing tray such that the engaging feature actuates the pivotable gate from a locked position to an unlocked position. The packaged food is prevented from sliding down when the pivotable gate is at the locked position. The packaged food is slidable relative to the individual dispensing tray when the pivotable gate is at the unlocked position.

  • Patent number: 10546368
    Abstract: A method and a display driver for compensating the perceptual bias of edge boost when driving a display panel are provided. The method can pre-process an input image to compensate for a perceptual bias of edge boost, e.g., at a contiguous group of color bands in the input image prior to sending the input image in a form of plural frames to a display panel for display. The method includes the steps of partitioning an input image into one or more grayscale regions, segmenting the grayscale regions into a plurality of color bands, detecting a subtle but perceivably significant change of color or luminance between two adjacent color bands, identifying a transition region and performing color dilution on the transition region. The display driver can include an input buffer, an image processor configured to execute the above method and an output buffer.

  • Patent number: 10452196
    Abstract: A capacitive sensing method comprising: driving a first excitation signal onto a sensor electrode, and driving a second excitation signal onto the embedded electrodes. Either the first or the second excitation signal has voltage oscillations of constant first amplitude, while the other has voltage oscillations of varying second amplitude. The second amplitude varies between a high amplitude value that is larger than the first amplitude by an amplitude difference and a low amplitude value that is smaller than the first amplitude by the same amplitude difference. The method further comprises using one or more integrators to integrate an electric current due to combined voltage oscillations of the first and the second excitation signals within an integration cycle, and generate an integrated signal for detecting a capacitive change on the sensor electrode; wherein the integration cycle comprises a plurality of voltage oscillations of the first and the second excitation signals.

  • Patent number: 10133405
    Abstract: A touch-sensing-enabled display module is provided. In the module, a display panel has an electroluminescent layer, such as an organic light emitting diode (OLED) layer, sandwiched between cathode electrodes and anode electrodes. The anode electrodes transmit touch-sensing signals induced at the display panel. The MSN performs multiplexing and summing on the touch-sensing signals to produce output-channel signals for touch sensing. The multiplexing and the summing are reconfigurable such that the touch-sensing signals are dynamically selected for summing to produce one or more output-channel signals. A touch controller measures the output-channel signals to generate touch data. The module further includes a display driver for driving the cathode and anode electrodes. By using the MSN, the display panel is able to provide adaptive sensor reconfiguration.

  • Patent number: 9954441
    Abstract: A slim and cost effective power module solution derived from the multiple-phase buck converter technology that addresses the problems of inductor thickness and excessive magnetic material use. Such power module solution utilizes a multi-phase constant current topology and a corresponding electronic controller to provide a constant current source for various OLED lighting applications. The multi-phase constant current topology comprises two or more inductor-flyback diode feedback loops. Each inductor-flyback diode feedback loop is triggered ON and OFF out-of-phase by a current controller, which senses and estimates the average current supplied to the load, and causes the adjustments to the average current supplied to the load by controlling the ON duration of the inductor-flyback diode feedback loops.

  • Publication number: 20120095336
    Abstract: A holding structure holds a biopsy needle and a HIFU transducer to allow smooth and accurate delivery of the HIFU beam at the interface of the liver, where bleeding will occur. This manipulator structure performs the biopsy and HIFU through the percutaneous approach. In addition, the procedure is imaged by an imaging ultrasound probe. The imaging ultrasound probe can track the needle entry site even when needle has been removed. The HIFU transducer fires a short pulse of HIFU in the needle tract to cause coagulation and stop bleeding.
