Abstract: A Bluetooth communication method having dynamic bandwidth allocation mechanism is provided including steps outlined below. A Bluetooth central apparatus and a Bluetooth peripheral apparatus perform a CIS communication according to a CIS technology. The Bluetooth central apparatus performs normal transmission mode packet communication behaviors with the Bluetooth peripheral apparatus operating under a normal transmission mode such that the Bluetooth peripheral apparatus performs an ACK signal transmission behavior in response. The Bluetooth central apparatus performs high bandwidth transmission mode packet communication behaviors with the Bluetooth peripheral apparatus operating under a high bandwidth transmission mode such that the Bluetooth peripheral apparatus selects at least one selected high bandwidth transmission mode packet communication behaviors and does not perform the ACK signal transmission behavior corresponding to the selected high bandwidth transmission mode packet communication behaviors.

Abstract: A Bluetooth communication method having bi-directional communication mechanism is provided including steps outlined below. A Bluetooth central apparatus and a Bluetooth peripheral apparatus perform a broadcast isochronous stream (BIS) communication according to a BIS technology. The Bluetooth central apparatus initiates one-way first packet communication behaviors performed with the Bluetooth peripheral apparatus operating under a normal transmission mode such that the Bluetooth peripheral apparatus does not react in response to the one-way first packet communication behaviors.

Abstract: A touchpad with a force sensing function and resistive pressure sensor thereof are disclosed. The resistive pressure sensor has a circuit board and a Wheatstone bridge circuit mounted on a deformation zone of the circuit board. The deformation zone deforms when a touchpad body is pressed by a force. The Wheatstone bridge circuit has a first upper-arm resistor, a first lower-arm resistor, a second upper-arm resistor and a second lower-arm resistor. The four arm resistors are in the deformation zone. A direction of current through the first lower-arm resistor and the second upper-arm resistor is different from a direction of current through the second lower-arm resistor and the first upper-arm resistor. Therefore, when the deformation zone of the circuit board deforms by the force, an output voltage of the Wheatstone bridge circuit is relatively increased to enhance a force sensitivity.

Abstract: The present invention provides a method fir emergency treatment by artificial intelligence. An artificial neural network is used as the artificial intelligence. Firstly the artificial neural network is trained to make injury classification, inspection list and medical material scheduling correctly. For a patient entering the hospital, the artificial neural network that has been successfully trained is used to accept a plurality of word vectors and various physiological information of the patient to generate an injury classification. The artificial neural network then determines whether the patient has to perform various inspection items respectively with the highest level of the injury classification. The artificial neural network then determines whether the patient needs the various medical materials with the highest level of the injury classification.

Abstract: A vibration body-pump device comprises a slab, a link rod and an electric motor. The slab is for supporting hands or feet, supported by a hinge, and connected with an inversely triangular bracket. One end of the hinge is pivotally connected to the bracket and the other end to an eccentric wheel. The electric motor has an axial shaft coaxially attached with the eccentric wheel, whereby, as the motor is rotating, the eccentric wheel will move accordingly, and whereby the link rod will be driven to make the slab vibrate. Therefore, the body-pump device will shake the whole body by vibrating the hands or feet put on the slab, achieving an effect of body pump.

Abstract: A collapsible tent skeleton frame includes a plurality of poles, a plurality of joints mounted respectively on the poles, a plurality of side ribs pivoted respectively to the joints, a top joint, and a plurality of upper ribs pivoted respectively to adjacent pairs of the side ribs and to the top joint. Each of the joints has two arms, each of which is formed with a recess that has a round inner end section and an extension. Each of the side ribs has a rounded end that is received in and that conforms to the inner end section of the recess in a respective one of the arms of a respective one of the joints.
