  • Publication number: 20240177949
    Abstract: A force-sensitive key module and a force-sensitive switch structure are provided. The force-sensitive switch structure includes a first protective layer, a second protective layer, a first conductive layer, a second conductive layer and a force-sensitive layer. The first protective layer receives a pressing force. The second conductive layer is aligned with the first conductive layer. The force-sensitive layer is installed on the first conductive layer or the second conductive layer. When the first protective layer receives the pressing force, an electric connection between the first conductive layer and the second conductive layer is established, and the force-sensitive layer generates an analog sensing signal in response to the pressing force. When a magnitude of the pressing force is changed, the analog sensing signal is correspondingly changed according to an impedance change of the force-sensitive layer.

  • Patent number: 11990761
    Abstract: A power supply system with current sharing includes a current sharing bus, a plurality of power supply units, and a plurality of controllers. The power supply units are connected to each other through the current sharing bus. Each power supply unit provides a current sharing signal value to the current sharing bus, and provides an output current to a load. Each controller receives current sharing signal values provided from other power supply units and current signal values corresponding to the output currents. When determining that the current signal value is less than a reference current sharing signal value, the controller increases an output voltage of the power supply unit to increase the output current. Otherwise, the controller decreases the output voltage to decrease the output current so that so that the output currents of the power supply units are shared to supply power to the load.

  • Publication number: 20240156440
    Abstract: A method of reconstructing transcranial images using a dual-mode ultrasonic phased array includes steps of: controlling channels to emit energy toward an intracranial target point of a patient; respectively generating backscattered radiofrequency (RF) data by using the channels to receive backscattered energy reflected from the intracranial target; and reconstructing an acoustic distribution image based on those backscattered RF data in real-time. Compared with Pre-Treatment Ray Tracing Method, the present invention can display intracranial pressure distribution in real-time; compared with MR Thermometry, the present invention can be applied to low-energy applications without temperature change; and compared with Passive Cavitation Imaging, the present invention can stably present acoustic distribution images without relying on microbubbles.
