Abstract: In accordance with an embodiment, a method for displaying an operation track includes: determining that a first touch point on a touchscreen is in a continuous writing state; and in response to detecting that at least two touch points exist on the touchscreen, displaying input content on the touchscreen based on a movement track of the first touch point, wherein the at least two touch points comprise the first touch point.

Abstract: A battery includes a housing, an electrode assembly, a first bonding part, and a second bonding part. The electrode assembly includes a body portion and a first metal portion. The first metal portion protrudes from the body portion along a first direction. The body portion includes a first protruding portion, a first portion, and a second protruding portion that are connected in sequence. The first portion includes a first surface and a second surface disposed opposite to each other in the second direction. The first protruding portion includes a third surface located on a same side as the first surface and a fourth surface disposed opposite to the third surface. The second protruding portion includes a fifth surface located on the same side as the first surface and a sixth surface disposed opposite to the fifth surface. The first protruding portion includes a seventh surface in the first direction.

Abstract: A power distribution unit includes a housing, a plurality of power outlets disposed within the housing, and a dynamic illumination element operable in a user selected one of a plurality of distinct colors. Systems and methods of color coding input power paths to power distribution units are also described. The power distribution units are universally used in different color coded combinations with increased manufacturing and supply chain efficiencies, and simplified customer order processing.
