    摘要: A parent node transmits a third specific message to child nodes as a broadcast message if a first specific message indicating the start of the child node collides with another message so that normal receiving cannot be performed. Then, the parent node sequentially transmits second specific messages to each child node and then receives responses to recognize the states of the children nodes. The parent node transmits a specific message indicating a realization of a sleeping state as a broadcast message to the children nodes, followed by transmitting a specific message when data to be transmitted from the child node has been generated. The parent node cancels the sleeping state when it receives the specific message.

    摘要: A communication apparatus transmits a test message in one direction by the transmitting unit having narrow directivity capable of changing the transmitting direction, and an indication message which indicates that the test message is being transmitted by a transmitting unit having non directivity. Accordingly, the indication message is transmitted at least to the communicating party's apparatus. Subsequently, the transmitting direction of the test message is sequentially changed, and a similar process is performed. When the communicating party's apparatus detects a reception of the indication message, information indicating a level of the test message is transmitted to the transmitting apparatus as a response. The communication apparatus at the transmitting side detects the direction where the communicating party exists by receiving the information indicating the level. Hereinafter, the information communication is performed to adjust the transmitting unit of narrow directivity to the determined direction.

    摘要: An electronic apparatus comprising a plurality of loads, which are separately driven by a plurality of batteries, further comprises a switching device which automatically changes a system of connection between the batteries and the loads in accordance with the conditions of the electronic apparatus. Such conditions of the electronic apparatus include the remaining capacities of the batteries, load changes in the loads, and temperature changes in the electronic apparatus. An electronic apparatus provided with a system clock generating device and a peak load device comprises a system clock controller which suspends the supply of a system clock or divides the system clock while a peak voltage is being generated. A drive controller changes the connection between the first and second batteries in accordance with detected remaining capacities of the first and second batteries.

    摘要: A pointed-position detecting apparatus where image output unit visually displays an image, and image input unit inputs the displayed visible image. The input visible image is stored into memory as an original image. The visible image is partially changed by using a manipulation device such as a laser pointer or a pointing rod, and the visible image with the partially-changed area is inputted from the image input unit. Controller extract the changed image area from the input visible image, and detects a pointed position based on the changed image area. Thus, the phenomenon where a user's action with respect to a displayed image is reflected as a change in the image is utilized to detect coordinates and motion at the image area as the object of change.
