Abstract: There is provided a control chip including a microcontroller unit (MCU), a bus arbiter, a first bus, a second bus, a void hardware, a cache controller, a flash controller and a flash memory, wherein the flash memory is recorded with a firmware. When the MCU does not receive an update instruction, the bus arbiter reads, according to a function command of the MCU, a function return value associated with the function command from the flash memory via the first bus, the cache controller and the flash controller. When the MCU receives the update instruction, the bus arbiter updates the firmware in the flash memory via the second bus and the flash controller, and the void hardware actively replies a void return value associated with the function command to the MCU to replace the function return value.

Abstract: A method and node for processing messages within an Internet of Things (IoT) network and network packet thereof are provided. Multiple fields of a header of a network packet broadcasted over the IoT network are referred to in the method. When a node receives a network packet broadcasted over the IOT network, it checks if the node's ID is recorded in an ID field of the network packet. The node ID is added to the network packet if the network packet does not record the node ID, and the network packet is then broadcasted to the IOT network; otherwise, the network packet is not broadcasted if the node ID has been recorded in the ID field. The node also performs a function indicated in a function field of the network packet when the node ID is not recorded in the network packet.

Abstract: An optical detection device is applied to an organism and includes a light emitting module, an optical detection module and an operation processor. The light emitting module includes a plurality of light emitters arranged along a first direction. The optical detection module includes a plurality of optical sensors arranged along a second direction and symmetrically relative to the light emitting module. The second direction is substantially different from the first direction. The optical sensors are substantially placed more outward from a center of the optical detection device than the light emitters. The operation processor is electrically connected to the optical detection module. The operation processor is adapted to analyze signal variation in the plurality of light emitters acquired by each of the plurality of optical sensors for determining a physiological feature of the organism.

Abstract: There is provided a touch force sensor including a first drive electrode, a second drive electrode and a receiving electrode. The first drive electrode is used to form a first capacitance with the receiving electrode. The second drive electrode is used to form a second capacitance with the receiving electrode. The receiving electrode shields the first drive electrode such that when a conductor approaches the receiving electrode, only the second capacitance is changed but the first capacitance is not changed. The first capacitance is changed only when the conductor gives a force upon the receiving electrode.
