Abstract: To Provide a scent provision apparatus capable of providing a scent to a user at a proper timing and preventing the provision of a scent at an unintended timing. Provided is a scent provision apparatus 200 that includes a main body section 201 and an air flow control unit 203. The main body section 201 has an opening portion 207 for discharging or taking in a scent-containing air flow that contains a scent. The air flow control unit 203 controls characteristics of the scent-containing air flow discharged or taken in from the opening portion 207. The air flow control unit 203 can generate a control air flow for accelerating and decelerating and/or diffusing the scent-containing air flow and can also generate a control air flow for interrupting a flow of the scent-containing air flow.

Abstract: The present disclosure relates to an autonomous mobile device, a control method, and a program which enable higher-speed self-position estimation with higher accuracy and with a smaller calculation load. Provided is an autonomous mobile device including: a sensor unit including at least a first sensor that detects an angular velocity, a second sensor that is installed in a housing and detects a speed of a wheel, and a third sensor that detects a displacement amount on a two-dimensional plane; and a self-position estimation unit that estimates a self-position on the basis of parameters calculated by the sensor unit, the self-position estimation unit using a predetermined parameter suitable for a predetermined condition among the parameters of the respective sensors calculated by the sensor unit when estimating the self-position. The present disclosure can be applied to, for example, an autonomous mobile robot device.

Abstract: A perfume holding member 101 includes: a perfume holder 208 that holds perfume; a holding space 209 where the perfume holder is disposed; a first opening 202 and a second opening 211 that open the holding space to the outside; movable portions 204 and 210 that move so as to open and close the first opening and the second opening; and a tolerance absorbing portion 207 that absorbs a tolerance between the first opening/closing position of the first opening of the movable portion and the second opening/closing position of the second opening of the movable portion. The holding space has an airflow passage including the first opening and the second opening, and the movable portions close the first opening and the second opening in a steady state and open the first opening and the second opening when the holding space is opened.

Abstract: Communication with a user is more naturally and effectively realized. An information processing apparatus includes an autonomous mobile body (10) that travels while maintaining an inverted state, and an operation control unit (230) that controls an operation of the autonomous mobile body. The autonomous mobile body includes a main body (10), two wheels (570) mounted on the main body, and a drive mechanism (565) that drives the two wheels. The operation control unit controls the drive mechanism to maintain the inverted state of the autonomous mobile body by the two wheels in a first state, and make the autonomous mobile body come to rest by the two wheels and a bottom of the main body when the autonomous mobile body transfers from the first state to a second state.

Abstract: The present disclosure relates to an imaging element and a method for controlling an imaging element, an imaging apparatus, and an electronic apparatus that can reduce the size of the imaging element and can reduce power consumption. First, a gray code corresponding to a P-phase pixel signal of each pixel is converted into a binary code. Then, a difference between a binary code corresponding to the converted same bit and a binary code of the pixel signal in which all bits are 0 and which is latched in a temporary latch is continuously calculated and is latched as the binary code of the P-phase pixel signal in the temporary latch. Then, a gray code corresponding to a D-phase pixel signal of each pixel is converted into a binary code. Then, a difference between a binary code corresponding to the converted same bit and the binary code of P-phase the pixel signal which is latched in the temporary latch is continuously calculated. The present disclosure can be applied to an imaging apparatus.
