Abstract: A server system to manage esports live distribution distributes, to a viewer terminal, data for displaying an image of gameplay by players on the viewer terminal, and situation data. The situation data describes various situations, such as a viewer's watching situation, a game progress status, a player's operation situation, a reward generation situation, a posting situation of comments such as cheers, and an evaluation situation of players by viewers. In the viewer terminal, various types of situation data are compared with predetermined screen configuration change conditions, and when some of the conditions is satisfied, the present configuration of a watching screen is changed to a screen configuration associated with the satisfied condition to provide information for the viewer in such a manner as to facilitate understanding of a situation on each occasion.

Abstract: A forced-ventilation device ventilates a compartment of a vehicle by forced ventilation by actuating a blower of an air-conditioning device of the vehicle when the compartment is left at a high temperature. When a mode for forced ventilation has been set by the user, when a mobile device approaching the vehicle together with a user enters a predetermined detection area within which the mobile device is detectable by a response signal, and when the response signal is successfully verified, a control portion switches ON an ignition switch of the vehicle, opens one or two or more windows using an opening and closing mechanism, and directs the air-conditioning device to actuate the blower.

Abstract: When a viewer executes a predetermined present operation, an item is selected from items that are possessed by the viewer, and is given to a player who is selected as a destination. Alternatively, an item that is purchased by the viewer is given to a player who is selected as a destination. When the player uses the presented item, a reward is given to the viewer who provided the present. This can make watching of gameplay images to be more attractive. Further, this allows the viewer to provide assistance more than cheering up to the player who performs the gameplay, and allows the viewer to feel a certain sense of unity with the player.

Abstract: A rotation information detection device detects rotation information of a DC motor based on a surge component waveform superimposed on a voltage waveform between the terminals of the DC motor or a current waveform of the DC motor, a circuit is provided which supplies a current of a current value Ipwm 45% during motor forward rotation or Ipwm 55% during reverse motor rotation to the motor over the period from when the motor starts braking operation to when it stops.

Abstract: A demodulator includes a count section, a synchronization timing setting section, and a code judgment section. The count section has four counters that count a number of waves of an FSK-modulated digital signal at different timing within a bit time width. The synchronization timing setting section designates a synchronized timing signal based on the count value of the count section. Then, the code judgment section compares the count value with a threshold value to judge the signal level, thereby decoding the digital signal.

Abstract: An inventive voltage-controlled ring oscillator provides a relatively stable oscillation frequency even with a lower power supply voltage. The oscillator includes an odd number of inverters and a variable delay circuit connected in a ring. The variable delay circuit comprises first and second control terminals to which first and second control signals that determine the amount of delay are applied; and a switching circuit including a first and second switching elements each comprising a MOS transistor.
