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.

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.

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.

An ergonomic pillow comprises a body including an inclined surface on either side, an arcuate central recess, and a slope near either side extended from the inclined surface to the recess so that either slope has the highest elevation on a top surface of the body; a front lengthwise projection member having a front slant extended from a bottom of the body adjacent to the recess; first and second cavities on the bottom of the body adjacent to either side and disposed corresponding to either slope; and an elongate third cavity at an underside of the projection member having the same orientation as the projection member. The pillow appropriately support face, ear, spine and shoulder for relaxing head and spine of a user in face-up or side sleeping.
