Abstract: A highly safe power storage system is provided. If n (n is an integer over or equal to three) secondary batteries are used in a vehicle such as an electric vehicle, a circuit configuration is used with which the condition of each secondary battery is monitored using an anomaly detection unit; and if an anomaly such as a micro-short circuit is detected, only the detected anomalous secondary battery is electrically separated from the charging system or the discharging system. At least one microcomputer monitors anomalies in n secondary batteries consecutively, selects the anomalous secondary battery or the detected secondary battery which causes an anomaly, and gives an instruction to bypass the secondary battery with each switch.

Abstract: It is difficult to know the remaining amount and the degradation state of a power storage device, and it is also difficult to estimate how long the power storage device can be used. Data obtained through midway discharge and mid-to-full charge is used as the learning data to calculate the degradation state and the capacity. In other words, the learning data includes both a discharge curve of midway discharge and a charge curve of mid-to-full charge, and neural network processing is performed with the use of the learned data.

Abstract: A display device whose aspect ratio can be changed is provided. The display device includes a plurality of display units and a plurality of driver circuit units. The plurality of display units each include a light-emitting portion and a connection region. The plurality of driver circuit units each include a driver circuit portion and a connection region. The connection regions of the adjacent units overlap with each other and one shaft passes through the connection regions. The adjacent units are electrically connected to each other with the one shaft. With such a structure, an angle between the adjacent units electrically connected to each other with one shaft can be changed, which enables the aspect ratio of the display device to be changed.

Abstract: A method and an apparatus for manufacturing an object which involve a separation technique are provided. A first substrate provided with an object is attached to a second substrate and is then suction-fixed by using a suction chuck (also referred to as a suction stage or a vacuum chuck) including portions with different suction capabilities or by using its functional equivalent, and the second substrate is separated from the first substrate. Accordingly, the object is separated from the first substrate and transferred to the second substrate. An apparatus for achieving this is also provided. A substrate fixture surface of the suction chuck or its functional equivalent includes a plurality of portions provided with suction micro-holes and a portion provided with no holes. Owing to the plurality of portions provided with suction micro-holes, a plurality of objects can be transferred from the first substrate to the second substrate.

Abstract: A highly reliable light-emitting device is provided. A yield in a manufacturing process of a light-emitting device is increased. A light-emitting device is provided in which a non-light-emitting portion having a frame-like shape outside a light-emitting portion includes a portion thinner than the light-emitting portion. A light-emitting element and a bonding layer are formed over a substrate. The light-emitting element is sealed by overlapping a pair of substrates and curing the bonding layer. Then, while the cured bonding layer is heated, pressure is applied to at least a portion of the non-light-emitting portion with a member having a projection.
