  • Patent number: 11426327
    Abstract: Hand-controlled physiotherapy equipment contains: a first electrode and a second electrode which are connected with living creatures so as to form a closed loop, an electrical stimulation system, a signal receiving unit, and a signal identification unit. The electrical stimulation system includes a sensing unit. The signal receiving unit is connected with the sensing unit in a wired manner or a wireless manner, the signal identification unit is configured to transform loop signals into time series signals, wherein when each of the time series signals has a specific interruption signal and a specific recovery signal, each time series signal triggers a mode adjustment signal in a control module. The control module includes a predetermined comparison database, and the comparison database has multiple set modes, wherein the multiple set modes respectively have multiple interruption signals and multiple recovery signals.

  • Patent number: 8759746
    Abstract: A rotary encoder and an optical wheel for the rotary encoder are provided. The rotary encoder further includes a light source module, a code plate and an optical sensor module. The light source module is coupled with the code plate. The optical wheel is rotary, and has imaging elements arranged annularly; at least one of the imaging elements is coupled with the code plate. The optical sensor module is coupled with at least one of the imaging elements. The light source module emits lights to the code plate, and the lights passing through the code plate forms an image which is then transmitted to the optical sensor module via the imaging element. When the optical wheel rotates, the image moves accordingly. The optical sensor module senses that the image moves. A method for generating a zeroing signal of a rotary encoder and a liner encoder are also provided.

  • Patent number: 5101365
    Abstract: A computer system which has a display memory for storing information to be presented on an output display, and a full screen bitmapped window identification memory for storing information regarding window position on an output display, and uses circuitry for comparing incoming information with information stored in the window identification memory to determine whether the incoming information should appear in a particular window of the output display, and also includes a second full screen bitmapped memory normally utilized for storing information indicative of other than window position on an output display and utilizes circuitry for selectively storing information in the second memory regarding window position on the output display when additional windows are required.

  • Patent number: 5050102
    Abstract: An apparatus for rapidly switching between output display frames using a shared frame identification memory is disclosed which has particular application to high resolution graphics for animation. Through a plurality of comparison circuitry, the apparatus enables a frame to be displayed during the clock cycles when the frame identification memory is read and during the clock cycles when the frame identification memory is provided with input, thereby, allowing a frame identification memory to be shared by two output display memories. As a result the rapid switching between output display frames sufficient for animation may be achieved with less hardware.
