Abstract: A method and system for detecting short-term stress of a subject person and generating alerts in an indoor environment are disclosed. The system may receive data on the subject person's heart rate, galvanic skin response, and accelerometer movement from a wearable device, and also capture image frames through a camera. After that, the system may perform bio-signal analysis in accordance with the heart rate and the galvanic skin response data, and perform skeletal motion analysis in accordance with the image frames. Based on bio-signal index and skin conductance index generated from the bin-signal analysis and skeletal motion analysis respectively, the system may perform data fusion to determine the short-term stress.

Abstract: The present invention describes an extraction system (100,100a) for expediting removal of a footing (105) that is embedded in a seabed or marine floor. The extraction system provides a supply of pressurized fluid (140) to a chamber from where the pressurized fluid exudes through porous members (122,122a, etc) located on the base (114) of the footing (105). When an uplifting force is applied to the footing (105) for its removal, the pressurized fluid (140) exudes out through the porous member (122,122a, etc.) to compensate or reduce suction induced beneath the footing, without fluidizing or channeling of the seabed soil, thereby expediting removal of the footing (105).

Abstract: A toy figurine USB flash drive comprising a casing in the form of a toy figurine which is divided into a body casing which has a torso with four limbs and a head casing which can be connected with or removed from the neck area of the torso; a printed circuit board (PCB) which is disposed inside the torso; a standard type-A USB connector one end of it is mounted on the PCB and the other end of it protrudes from the neck area of the torso and can be covered by the head casing; a USB mass storage controller which is mounted on the PCB to drive the onboard memory; a NAND flash memory chip which is mounted on the PCB to store data; and a crystal oscillator which is mounted on the PCB to control data output through a phase-locked loop; wherein: the four limbs are pivotally connected to the torso forming the two arms and the two legs of the toy figurine, each of the arms can be rotated and raised above the shoulder to rest against the neighboring surface of a USB port into which the USB connector is plugged for supp
