  • Publication number: 20150291338
    Abstract: A desiccant container structure includes a main body, a lid, and a desiccant storing element having at least a viewing portion made of a transparent material. The main body is formed with a plurality of through holes and an accommodation space for accommodating an object. The desiccant storing element is formed with a storing chamber for accommodating a desiccant and communicating with the main body through the plurality of through holes. The desiccant in the desiccant storing element is capable of absorbing moisture from the accommodation space through the plurality of through holes for maintaining the object in a dry state, and a state of the desiccant is capable of being viewed directly through the transparent viewing portion.

  • Publication number: 20140367286
    Abstract: A can structure for storing testing strip, mainly consisting of a can body, a cover and a moisture-proof can. After the cover is put on the can body, an elastic mechanism on the cover is pressed, and then the elastic mechanism restores its position automatically so that a space inside the can body is changed through reciprocation of the elastic mechanism to make a pressure outside the can body higher than a pressure inside the can body. This can improve the tightness of engagement between the can body and the cover to ensure that the can body is maintained at a completely closed state to effectively store the testing strip, and by means of a desiccant filled in the moisture-proof can, the testing strip is kept dry.

  • Patent number: 8595814
    Abstract: Disclosed are systems and methods for providing transport layer encryption with an intermediate electronic message managing service interposed in a message path of an electronic message to be sent from a sending server to an intended receiving server across a computer network. To implement TLS in such a managed e-mail services context, given that a managed e-mail service is inserted into the message delivery path, the transport layer security protocols are simultaneously established along both the link from the sending server to the managed e-mail service and from the receiving server to the managed e-mail service, with the managed e-mail service providing a “proxy” connection for communication between the sending server and the receiving server.

  • Publication number: 20130256132
    Abstract: A test strip structure is provided, and more particularly to a blood glucose test strip, which facilitates permeating blood, comprises a plurality of conductive strips disposed over a top of a base layer, and a first insulation glue layer covering with the conductive strip. A roof plate layer is disposed over a top of the first insulation glue layer. One end of the conductive strip is capable of receiving a detection of a blood glucose machine while another end is disposed with a reaction layer. The first insulation glue layer is formed with a notch portion relative to the reaction layer. The notch portion is formed with a notch port, which is at one end of the base layer, capable of providing blood to permeate into the reaction layer. The first insulation glue layer has a ventilation gutter communicating with the notch portion.

  • Publication number: 20100208767
    Abstract: An ear thermometer using optical fiber transmission includes a housing, an optical fiber conductor, a thermal sensor, and a circuit board. When the ear thermometer is used to take a human body temperature, a convex surface at one end of the optical fiber conductor collects thermal radiation caused by the human body temperature inside a human auditory meatus, and the optical fiber conductor transmits the thermal radiation to an opposite end thereof so that a convex surface at the opposite end evenly scatters the thermal radiation toward the thermal sensor. Thereby the thermal sensor senses the thermal radiation and determines the human body temperature accordingly.
