Abstract: A semiconductor memory device has a plastic package including an inductor, a first memory chip including a booster circuit that boosts a voltage from a first voltage to a second voltage using the inductor, and a second memory chip having a terminal supplied with the second voltage from the first memory chip.

Abstract: A navigation system includes a detector configured to detect a situation in a movable object, a determiner configured to determine a degree of activity of conversation in the movable object on the basis of a detection result by the detector, a movement plan setter configured to set a movement plan on the basis of setting information which is set by a user, and to change at least part of the set movement plan on the basis of a determination result by the determiner, and a navigator configured to navigate the movable object on the basis of the movement plan which is set or changed by the movement plan setter.

Abstract: A movement plan provision system includes an analyzer configured to analyze an attribute of a user on the basis of life information related to a life of the user, which is information collected by an electronic apparatus present in a life space of the user, a group generator configured to generate a group to which a user having a predetermined relationship belongs, on the basis of the attribute of the user analyzed by the analyzer, and a movement plan provider configured to provide a movement plan according to the relationship of the group generated by the group generator to a plurality of users belonging to the group generated by the group generator.

Abstract: A meeting support system includes a movement means acquirer configured to acquire information related to a movement means of a first user, a movement means selector configured to select a movement means of a second user who meets with the first user on the basis of the information related to the movement means of the first user acquired by the movement means acquirer, and a provider configured to provide the movement means of the second user selected by the movement means selector to the second user.
