An electro-optic display having a plurality of pixels is driven from a first image to a second image using a first drive scheme, and then from the second image to a third image using a second drive scheme different from the first drive scheme and having at least one impulse differential gray level having an impulse potential different from the corresponding gray level in the first drive scheme. Each pixel which is in an impulse differential gray level in the second image is driven from the second image to the third image using a modified version of the second drive scheme which reduces its impulse differential The subsequent transition from the third image to a fourth image is also conducted using the modified second drive scheme but after a limited number of transitions using the modified second drive scheme, all subsequent transitions are conducted using the unmodified second drive scheme.

Electro-optic displays and methods for driving the same

A variety of methods for driving electro-optic displays so as to reduce visible artifacts are described. Such methods include (a) applying a first drive scheme to a non-zero minor proportion of the pixels of the display and a second drive scheme to the remaining pixels, the pixels using the first drive scheme being changed at each transition; (b) using two different drive schemes on different groups of pixels so that pixels in differing groups undergoing the same transition will not experience the same waveform; (c) applying either a balanced pulse pair or a top-off pulse to a pixel undergoing a white-to-white transition and lying adjacent a pixel undergoing a visible transition; (d) driving extra pixels where the boundary between a driven and undriven area would otherwise fall along a straight line; and (e) driving a display with both DC balanced and DC imbalanced drive schemes, maintaining an impulse bank value for the DC imbalance and modifying transitions to reduce the impulse bank value.

Methods for driving electro-optic displays

An autonomous transport robot for transporting a payload, the autonomous transport robot includes a payload bed having at least one reference datum surface and at least one payload justification device, the at least one payload justification device being configured to position a payload on the payload bed in substantial contact with the at least one reference datum surface to place the payload in a predetermined position on the payload bed.

Storage material handling system

Methods are described for sequentially rendering fonts at multiple bit depths while reducing differences in visual appearance between the fonts rendered at different bit depths. The same hinting may be used for rendering the font at two different bit depths. Methods for reducing artifacts including edge artifacts also are described, including the use of font masks for updating electro-optic displays.

Font control for electro-optic displays and related apparatus and methods

An electro-optic display comprises, in order, a light-transmissive electrically-conductive layer; a layer of a solid electro-optic material; and a backplane () bearing a plurality of pixel electrodes, a peripheral portion of the backplane extending outwardly beyond the layer of solid electro-optic material and bearing a plurality of radiation generating means () and a plurality of radiation detecting means (), the radiation generating means and radiation detecting means together being arranged to act as a touch screen.

Electro-optic displays with touch sensors and/or tactile feedback

A storage fill and retrieval system includes fixed storage locations distributed in a storage space and defining at least one human pick zone having at least one collection tote location, at least one autonomous mobile robot configured for holding and transporting a tote within the storage space and having an end effector arranged for autonomous transfer of the tote between the at least one robot and a tote holding station and a collection tote location, and a storage management system communicably connected to the at least one robot and configured to associate each robot with a human pick zone, wherein the at least one robot is configured to transport the tote to the collection tote location of each associated human pick zone, and wherein each collection tote location is arranged for human picker access and defines an interface between a human picker and the at least one robot.
