  • Publication number: 20230320589
    Abstract: A sole data collection device and a sole data collection method are disclosed. The sole data collection device includes an image capture module, a temperature detection module and a monofilament testing module. The sole data collection device is used for collecting the sole data of a user, and the sole data is transmitted to a cloud server. The sole data collection device and the sole data collection method are not only convenient for a user to collect sole data at home at any time, but also allow the user's caregiver and/or relevant medical care personnel to extract the sole data from the cloud server to screen the user's plantar condition, so as to solve the problem that it is time-consuming and costly to go to a medical institution for relevant examinations.

  • Patent number: 9898436
    Abstract: A data transmission system and a transmission method thereof are provided. The data transmission system includes a first electronic apparatus and a second electronic apparatus. The first electronic apparatus includes a first clock pin and a first data pin. The second electronic apparatus includes a second clock pin and a second data pin. In a connecting detection mode, the first electronic apparatus transmits a first detection signal to the first clock pin and drives the first data pin to a reference logic level. The second electronic apparatus transmits a second detection signal to the second clock pin and drives the second data pin to the reference logic level. The first electronic apparatus determines whether the first and the second electronic apparatuses are connected to each other according to whether at least one of signals on the first clock pin and on the first data pin is varied or not.

  • Publication number: 20070292659
    Abstract: The present invention discloses a high transmittance touch panel, which comprises a substrate and at least one multi-layer anti-reflection coating structure coated on the front side of the substrate. The multi-layer anti-reflection coating structure is a four-layer structure, and the refractive indexes of those layers are high, low, high, and low sequentially from the side neighboring the substrate. The outmost layer is a protective layer having a refractive index within from 1.3 to 1.5 and a thickness of at least 0.1 ?m and a hardness reaching 9H of ASTM-D3363. Via the protective layer, not only the transmittance of the touch panel of the present invention can reach over 92% according to ASTM-D1003, but also the abrasion resistance of the touch panel surface can be enhanced.
