Abstract: An electric power control apparatus, an electric power control method, and an electric power feeding system by which the maximum operating point of a generating element such as a solar battery can be controlled to be maintained, and electric power loss can be avoided. The electric power control apparatus is provided with an electric power path switch unit to which a plurality of generating elements can be connected, and a voltage conversion unit that converts a voltage level which is generated by the generating elements and supplied via the electric power path switch unit. The electric power path switch unit includes a first connection switching function which switches between series connection and parallel connection for the plurality of generating elements, and a second connection switching function which switches between connected and non-connected to an input side of the voltage conversion unit for the generating elements connected in series or parallel.

Abstract: There is provided a projection device including a projecting unit that projects an image onto a screen, an acquiring unit that acquires image data of the image to be projected onto the screen, a generating unit that generates first pixel data representing pixels of first spot beams to be projected onto the screen without overlapping with each other among a plurality of spot beams to be projected at different timings based on the image data, and a driving control unit that controls driving of the projecting unit based on the first pixel data in a manner that the first spot beams are projected onto the screen as pixels of the image data.

Abstract: There is provided an image output device including a projectable region calculating unit that calculates a projectable region which is a region on a screen in which laser beam is projectable based on a trajectory in which scanning with the laser beam is performed using information specifying the screen onto which an image is projected by two-dimensional scanning with the laser beam, a projection window setting unit that causes the laser beam to be emitted and sets a projection window serving as a range in which the image is projected in the projectable region, and a generating unit that generates a pixel value of each of positions corresponding to pixels included in the image within the projection window on the screen for each pixel in a manner that the image is projected in the range set by the projection window.

Abstract: Disclosed herein is a cache memory including: a tag storage section including entries each including a tag address and a pending indication portion, at least one of the entries being to be referred to by a first address portion of an access address; a data storage section; a tag control section configured to compare a second address portion of the access address with the tag address included in each of the entries referred to to detect an entry whose tag address matches the second address portion, and, when the pending indication portion included in the detected entry indicates pending, cause an access related to the access address to be suspended; and a data control section configured to select data corresponding to the detected entry from among the data storage section, when the pending indication portion included in the detected entry does not indicate pending.
