Abstract: A portable circulatory shock detecting device is disclosed. In a measurement device, a body surface vibration data of a subject is sensed by a vibration-sensing module and transmitted to an electronic device by a communication interface. A heartbeat acquisition process is executed to obtain a heartbeat vibration data of the subject by a monitoring module of the electronic device, a circulatory shock detection process is executed to generate a heartbeat evaluation based on the heartbeat vibration data, and a circulatory shock alarm is outputted while the heartbeat evaluation is assessed as a circulatory shock risk.

Abstract: A retroreflective screen comprising including a film having a surface including a plurality of microrecesses, each microrecess having the shape of a truncated pyramid, the lateral walls and the back of each microrecess being coated with a reflective metallization.

Abstract: A portable device for monitoring vascular access status is disclosed. The portable device comprises a measurement device and a monitoring module. The measurement device senses vibration data induced by blood flow over certain part of a vascular access of a subject via a vibration-sensing module, and sends the sensed data to outside via its communication module. The monitor module controls an electronic device to receive the sensed data and determines a vibration evaluation index corresponding to a status of the part of the vascular access. The portable device for monitoring vascular access status of the present disclosed example has advantages of small size, easy to carry, low cost, and so on, so as to be applicable to home vascular access status monitor.

Abstract: A water saving toilet device comprises a drain pipe of a basin connected with a flush unit of a toilet, thereby providing the wastewater, which is produced after the basin is used, into the flush unit of the toilet via the drain pipe to be a water for cleaning the toilet after the user used the toilet, achieving the effect of water saving.

Abstract: A luggage scooter is revealed. A moveable and foldable foot rest unit is disposed on a front surface of a box. A vertical rod arranged with a handle is connected to a front end of the foot rest unit. A front wheel is set on bottom of the vertical rod while a transmission wheel is disposed on a bottom side of the box and connected to a power source. Anti-tip wheels are arranged at bottom surface of the box. The foot rest unit and the vertical rod are mounted in the box so that the luggage scooter is used as a luggage for loading objects. While being used as a scooter, the foot rest unit is extended and users sit on the box with feet stepping thereon and hands holding the handle. A drive unit drives the power source to move the transmission wheel.

Abstract: A white light source is obtained by converting short wavelength color light emitted from a light emitting diode (LED). The conversion is achieved by covering the LED chip with a fluorescent glue. The LED chip is mounted on a split substrate, and the outer ends of the substrate serve as terminals for the LED. A wall may be erected around the LED chip to contain the fluorescent glue, and another transparent glue may be used to cover the fluorescent glue for protection.

Abstract: An optoelectronic device is placed in a through hole of an upper substrate and mounted on a lower substrate, which is stacked under the upper substrate. The through hole forms a focusing cup for the optoelectronic device. A metallic base plate can be inserted between the optoelectronic device and the lower substrate to enhance light reflection and heat removal. The through hole can be lined with metallic coating to enhance light reflection.
