  • Patent number: 11680755
    Abstract: An air-permeable carrier includes at least one temperature adjusting unit and a carrier body having a plurality of pores. The temperature adjusting unit includes an adhesive and a plurality of phase change microcapsules. The temperature adjusting unit is distributed and fixedly embedded within the carrier body by an adhesive-dispensing injection process, such that the temperature adjusting unit is filled in at least one of the pores in a partial region of the carrier body to form at least one temperature adjusting region at a position corresponding and proximate to the temperature adjusting unit. Each horizontal distance or vertical distance between any two adjacent temperature adjusting units can be substantially the same or different, so that when a user leans against the carrier, phase change microcapsules can be communicated with air from the surrounding environment through the pores to achieve the effect of heat adjustment.

  • Patent number: 10490052
    Abstract: A motion-sensing floor mat, an assembly of such floor mats, and a monitoring system with such floor mats are provided; wherein the floor mat can be joined with another such floor mat and electrically connected to a monitoring device to form the monitoring system; the monitoring device stores a queue list and a topology matrix and uses a topological algorithm to store the identification tag of each such floor mat detected into the queue list in order, to gradually establish the topology matrix for the floor mats detected; and to thereby obtain the relative positions of the floor mats detected. When any of the floor mats is subjected to pressure (e.g., when someone falls on the floor mat accidentally) and generates a sensing signal, the monitoring device can pinpoint the position of that floor mat (i.e., the location of the fall) rapidly according to the topology matrix.

  • Patent number: 9895004
    Abstract: A mat with a thermostatic layer between two layers of foam to reduce heat accumulation and the manufacturing process thereof, which includes a supporting foam layer, an air permeable foam layer, and the thermostatic layer; wherein the thermostatic layer lies on the top side of the supporting foam layer and includes phase change material (PCM) microcapsules and a bonding material; the air permeable foam layer has larger pores than the supporting foam layer, and has its bottom side attached to the thermostatic layer, and is thus bonded to the supporting foam layer via the bonding material. When a user lies on the air permeable foam layer, the user's body skin is not directly pressed against the PCM microcapsules, thereby allowing the PCM microcapsules to communicate with the ambient air through the pores in the air permeable foam layer and to dissipate heat rapidly for keeping the mat cool.

  • Publication number: 20150364023
    Abstract: The present invention is to provide a monitoring system including a plurality of motion sensing carpets and a monitoring device (e.g., a computer) electrically connected to one of the motion sensing carpets serving as a control unit while all the other motion sensing carpets directly or indirectly joined to the control unit serves as auxiliary units. The monitoring device is able to carry out a topology algorithm and then establish a topology matrix of the motion sensing carpets in a stepwise manner so as to obtain the relative location of each motion sensing carpet. When any of the motion sensing carpets is subjected to pressure caused by a senior member or child in the family toppling over thereon (e.g., an accident) and generates a sensing signal, the monitoring device can rapidly know from the topology matrix the exact location of the accident according to the sensing signal.

  • Patent number: 8943908
    Abstract: The present invention is to provide an imperceptible motion sensing device, which includes a non-conductive elastomer made of a pliable and elastic non-conductor (e.g., polyurethane) and having a bumpy side formed with at least one sunken portion thereon, at least one conductive fiber positioned in the at least one sunken portion respectively (e.g., by sewing), and a conductive elastomer made of a pliable and elastic conductor (e.g., a conductive foam or conductive rubber) and provided on the bumpy side of the non-conductive elastomer. When the sensing device is compressed by an external force, corresponding portions of the conductive elastomer and the non-conductive elastomer are compressed and deformed, causing contact and hence electrical connection between the conductive elastomer and the at least one conductive fiber. Thus, the imperceptible motion sensing device not only provides more accurate and more sensitive signal detection, but also ensures consistent performance even after long-term use.

  • Patent number: 8418289
    Abstract: The present invention is to provide an automated anti-snoring bed system, which includes a bed designed to support a user lying thereon and internally provided with a driving device, a sensing device able to send out a detection signal toward the user's chest at regular intervals of time and receive a reflected signal returning from the user in response to the detection signal, and a control device. When the sensing device determines that the user is snoring according to the reflected signal, the sensing device sends out a control command to the control device and the control device then drives the driving device to change the configuration of the bed to a mode for stopping the user from snoring. Thus, the user is prevented not only from sleep disorders, but also from sleep apnea which may otherwise jeopardize the user's sleeping quality and health.
