According to an aspect, there is provided a teaching device on which portable terminal equipment is mounted, the teaching device being used to teach operation to a robot. The teaching device includes a case section including a mounting surface on which the portable terminal equipment is mounted. The case section includes a first member including a stop switch for stopping the operation of the robot and configured to restrict the portable terminal equipment's moving in a first direction extending along the mounting surface and a second member provided to be capable of moving in the first direction relatively to the first member and configured to restrict the portable terminal equipment's moving in an opposite direction of the first direction.

Teaching device and robot system

A robot includes a robot arm, a drive unit that drives the robot arm, a first control unit that controls drive of the drive unit, a plurality of detection units at least one of which is an angular velocity sensor as an inertial sensor, and a wiring unit that series-connects the plurality of detection units and the first control unit.

Robot, controller, and robot system

A robot includes a first power supply that outputs first voltage, a first circuit that operates with the first voltage, a second power supply that outputs second voltage, a second circuit that operates with the second voltage, and a first protection section that causes the first circuit to operate based on the second voltage when the first power supply stops outputting the first voltage.

Robot

A driving method for driving an electrophoretic display apparatus, which has a display section including a plurality of pixels each having a pixel electrode and a common electrode opposing each other and an electrophoretic element interposed therebetween which includes electrophoretic particles, includes erasing a first image displayed on the display section, during a process of rewriting the first image into a second image. The driving method includes displaying the second image on the display section, during the process of rewriting the first image into the second image, wherein the corrected image data is image data obtained by correcting image data associated with the second image so as to reduce an area displaying the one gradation and expand an area displaying the other gradation in the second image.

Driving method for driving electrophoretic display apparatus, electrophoretic display apparatus, and electronic device

An image display device for displaying an image on a display panel is provided. The image display device includes a temperature variation rate detecting unit that detects a temperature variation rate of the display panel; a driving condition setting unit that sets driving conditions so as to display the image on the display panel in accordance with an image data of the image; a driving condition changing unit that changes the set driving conditions in accordance with the detected temperature variation rate; and a display panel driving unit that displays the image on the display panel by driving the display panel with the driving conditions changed by the driving condition changing unit.

Image display device and image display method

An image display apparatus that displays an image on a display includes: a temperature measuring unit that measures temperatures of a plurality of display regions of the display; a determining unit that determines whether or not a temperature difference between one of the plurality of display regions and the other display regions is larger than a threshold value on the basis of the temperatures measured by the temperature measuring unit; a driving condition setting unit that sets a driving condition for displaying the image on the display according to image data of the image; a driving condition changing unit that, in a case when the determining unit determines that the temperature difference is larger than the threshold value, changes the set driving condition to a driving condition different from that in a case in which the temperature difference is determined to be equal to or smaller than the threshold value; and a display driving unit that drives the display under the driving condition changed by the driving condition changing unit and displays the image on the display.

Image display apparatus and image display method

A cholesteric liquid crystal driving device according to the present invention includes a first driving circuit for displaying one part of the image data to be displayed by a cholesteric liquid crystal on a first scanning line by driving the cholesteric liquid crystal on the first scanning line in accordance with first and second cycles; and a second driving circuit for displaying the other part of the image data to be displayed by a cholesteric liquid crystal on a second scanning line by driving the cholesteric liquid crystal on the second scanning line in accordance with a third or fourth cycle.

Cholesteric liquid crystal driving device and driving method

The present invention is adapted to make all the pixels of electrophoretic displaywhite (step S) when light no longer incomes on the face of electrophoretic display('Yes' at step S) . When someone places the face of electrophoretic displayon a contact glass of a copy machine to copy the contents on electrophoretic displayas they are, all the contents currently displayed on electrophoretic displayis deleted. As the result, the present invention can prevent the contents on electrophoretic displayfrom being easily copied by the copy machine as they are.

Display device preventing unauthorized copying

There is provided a battery-driven electronic book reader for switchingly displaying each page of contents separated in predetermined pages on a cholesteric liquid crystal panel, wherein a remaining available battery level is detected (step S), the number of pages to be switchedly displayed on the cholesteric liquid crystal panel is calculated based on the detected remaining available battery level (step S), and the calculated number of pages is displayed on the cholesteric liquid crystal panel (step).
