A laser device according to one embodiment of the present disclosure includes a light source and a reflection-type polarizer. The light source causes laser light to oscillate. The reflection-type polarizer is disposed on an optical path of the laser light and has a transmission axis coinciding with a polarization direction of the laser light.

An electromagnetic radiation steering mechanism An electromagnetic radiation steering mechanism configured to steer electromagnetic radiation to address a specific location within a two-dimensional field of view comprising a first optical element having an associated first actuator configured to rotate the first optical element about a first rotational axis to change a first coordinate of a first steering axis in the two-dimensional field of view, a second optical element having an associated second actuator configured to rotate the second optical element about a second rotational axis to change a second coordinate of a second steering axis in the two-dimensional field of view, and an electromagnetic radiation manipulator optically disposed between the first and second optical elements. A first angle is defined between the first and second rotational axes and a second angle is defined between the first and second steering axes. The electromagnetic radiation manipulator is configured to introduce a difference between the first angle and the second angle.

Power to an electrical device is controlled using a phase control that changes a cutoff phase of an alternating current (AC) electrical signal delivered to the electrical device. The power delivered to the electrical device is increased to an operational level using the phase control. A level of the power delivered to the electrical device is maintained at the operational level using an integral half cycle control that selectively removes a plurality of half cycles from the AC electrical signal delivered to the electrical device such that a plurality of remaining half cycles in the AC electrical signal delivered to the electrical device have a frequency outside a range of sub-harmonic frequencies.

A recording device according to the present disclosure includes: a writer that rewrites schedule information visibly recorded on a recording medium and corresponding to a time from first schedule information to second schedule information; and a generator that generates the second schedule information on the basis of a time.

A printing apparatus includes a print head, a processor, and a drying mechanism. The print head ejects ink onto a printing medium located in a printing region to form an image. The processor is configured to control a duty that is an amount of ink ejected by the print head onto the printing medium per unit area. The drying mechanism includes a transport unit that transports the printing medium in a first direction and a heater that heats the printing medium. The drying mechanism is configured to dry the printing medium having the image formed thereon by the print head, by transporting, using the transport unit, the printing medium to a drying region in which the printing medium is dried by the heater. The processor controls drying of the printing medium performed by the drying mechanism in accordance with the duty.

A thermosensitive recording medium according to an embodiment of the present disclosure includes: a recording layer that includes a coloring compound having electron-donating property, a developer having electron-accepting property, a photothermal conversion agent, and a polymer material; and a protective member that is stacked on the recording layer, and has a convexo-concave shape in a plane.

A system includes an unpatterned heater configured to pre-heat a thermochromic coating disposed on a substrate to a first temperature. The thermochromic coating has a threshold temperature at which the thermochromic material undergoes a color change. The system also includes a patterned heater comprising multiple heating elements configured to heat selected pixels of the thermochromic coating to a temperature at or above the threshold temperature according to a predetermined pattern. An air gap is maintained between the multiple heating elements and the thermochromic material while the patterned heater is heating the thermochromic material. The air in the air gap heated to a second temperature.
