Abstract: The power supply device of an embodiment includes a first storage battery connected between a positive electrode terminal and a negative electrode terminal; a second storage battery connected in parallel with the first storage battery; a first switch that switches connection between a positive electrode of the first storage battery and the positive electrode terminal; a second switch that switches connection between a positive electrode of the second storage battery and the positive electrode terminal; and a battery management device that controls opening and closing of the first switch and the second switch, wherein energy density of the first storage battery is equal to or greater than energy density of the second storage battery, and wherein the first switch is normally closed and the second switch is normally open.

Abstract: In a vehicle-mounted display system, a spare attentiveness level deriving part derives a spare attentiveness level that is a parameter determined according to a state of a driver of a vehicle at a present moment and a risk level deriving part derives a risk level that is a parameter determined according to a risk level of an accident at the present moment. Then a display continuously displays a driving state mark that is a reference graphic, determined according to the spare attentiveness level and the risk level, while the driver is driving the vehicle. Therefore, the driver can continuously understand the own state and the risk level of an accident at the present moment.

Abstract: A use specifying unit specifies a “purpose of use” of a vehicle based on a running-data table. An application selection unit selects one or more information-related applications which are suitable for the “purpose of use”, from a plurality of information-related applications. Then, an execution inhibition unit inhibits execution of information-related applications which are not selected to be suitable for the specified purpose of the vehicle. As a result, it is possible to prevent information-related applications which are unnecessary for the “purpose of use” of the vehicle from being executed wastefully.

Abstract: The operation unit includes a shaft that receives by its one end a pressing force applied through a pressing operation by a finger/thumb, a rotating body that rotates about the shaft according to an operation by the finger/thumb within a movable range of the finger/thumb, a first sensor that detects a pressing force applied to the shaft in an axial direction of the shaft, a second sensor that detects a pressing force applied to the shaft in a direction other than the axial direction of the shaft, and a third sensor that detects a rotating state of the rotating body.

Abstract: An optical position input device is provided which enables simultaneously inputting of multiple points.

Abstract: A data recording medium for use in a game device comprises a first printed layer in which a first code pattern, which is detected by a first code pattern detecting unit of the game device, is printed and a second printed layer in which a second code pattern, which is detected by a second code pattern detecting unit of the game device, is printed. The second printed layer is overlaid on the first printed layer. Data based on a combination of the first and second code patterns is recorded in the first and second printed layers so that the data is recognizable to the game device as data intrinsic to the data recording medium. The game device detects the first and second code patterns by the first and second code pattern detecting units to make progress of a game according to the data.

Abstract: In a network game in which a plurality of game terminal devices are connected via a server, a RPG game is played by a team formed by game program characters operated by the respective game terminals. If there is a player at a game terminal who wishes to depart from the team, then the operating authority for that player's character are delegated to a player at another game terminal device. If the departed player returns to the game, the variable parameter values for the character are set to the variable parameter values at the time of departure.

Abstract: The present invention conducts rendering processing according to a prescribed priority relating to each polygon attribute. For example, rendering for semi-transparent polygons is conducted after rendering for opaque polygons. By this means, it is possible to carry out rendering for semi-transparent polygons reliably. Furthermore, rendering for polygons containing transparent portions is conducted after rendering for polygons not containing transparent portions. By this means, it is possible to reduce rendering processing for polygons containing transparent portions, as far as possible. Moreover, rendering processing is carried out for all background polygons together. Thereby, it is possible to carry out suitable depth cue processing for polygons positioned in the far distance of the screen.
