  • Publication number: 20240096135
    Abstract: There is provided a locker with a motion sensor. The motion sensor identifies whether an object is put into or taken out from the locker by calculating coordinates of the object using a motion detection algorithm, by calculating a moving vector of the object using an image time differential algorithm or by comparing a current image frame and a background image frame, and outputs a put-in signal and a taken-out signal to a post control system.

    Abstract: A floating image generation device is disclosed, which includes a light source, an image generation module, and a floating image generation unit. The image generation module is disposed above the light source and includes a shading unit and an image generation unit. The shading unit is capable of changing light transmissivity state. The image generation unit is disposed above the shading unit. The floating image generation unit is disposed above the image generation unit. The light source emits a light passing through the shading unit, the image generation unit, and the floating image generation unit to generate a first floating image when the shading unit is in a first light transmissivity state. The light source emits a light passing through the shading unit, the image generation unit, and the floating image generation unit to generate a second floating image when the shading unit is in a second light transmissivity state.

  • Patent number: 11426598
    Abstract: A reusable adhesive pad with embedded magnets consists of a layer of fibrous cloth with elasticity, a layer of silicone gel padding, and permanent magnets. The fibrous cloth with elasticity is made from fiber materials with a stretchable characteristic. The silicone gel padding is spread out fully and glued on one surface of the fibrous cloth with elasticity. In addition, the silicone gel padding is provided with holes that the permanent magnets with cylindrical or conical outers can be filled in and glued to the adhesive surface of the fibrous cloth with elasticity. Since the other sides of the permanent magnets protrude outwards the surface of the silicone gel padding, applying the invention to the human skin can perform the acupuncture and moxibustion treatment and the magneto-therapy to lessen painful discomfort.

  • Publication number: 20220040554
    Abstract: A swimming timer including a fluid container, a fluid channel, a fluid sensor, a control circuit board and a display device. The fluid channel is connected to the fluid container and the fluid sensor, and the control circuit board is wired with the fluid sensor and the display device. The fluid container is installed and mounted on a side-wall of a swimming lane. When a swimmer starts, turns and stops, the fluid container will be touched and compressed forcing the fluid inside to flow into the fluid channel. The fluid sensor detects the fluid flow and generates electronic signals accordingly for the control circuit board and the built-in timing and stopwatch program to use as the input commands of start, lap and stop to compute the swimming time and the number of swimming laps. The display device is to show the results for the swimmer reference.

  • Publication number: 20210069566
    Abstract: The objective of the invention is to provide a visual rhythmic guide device for swimming training capable of emitting rhythmical flashlights with a given frequency to lead the tempo of movements such as arm stroking and leg kicking for a swimmer. To achieve the objective, the device comprises a waterproof body to house components including a control circuit board, a timer, a gravity sensor (G-Sensor), a LED light source, a screen, a battery, a connection port and a set of input keys. When the device is given a frequency by a swimmer through the input keys, the LED light source will be driven to emit rhythmical flashlights in accordance with the given frequency. The swimmer is able to wear the device on anywhere of the body as long as the rhythmical flashlights can be sensed to adjust and practice the tempo of swimming movements.

  • Publication number: 20210069567
    Abstract: A limb motion measurement device for swimming training includes a sense glove and a sense shoe able to measure and collect the states of moving hands and feet of a swimmer in a training practice, including strength, displacement, velocity, bearing angle, number of times, frequency and time parameters, and to generate a serial of limb motion data of arm stroking and leg kicking motions. These organized and quantified limb motion data can be transmitted outwards to an external computer for the swimmer to study and to produce useful information of more efficient movements and tempos of swimming techniques. Accordingly, the limb motion measurement device for swimming training can be applied to improve swimming techniques in a scientific way.
