Abstract: A method of charging a plurality of battery packs may include applying a first constant current to a battery for a first period of time until a first charging voltage value is reached for the battery to define a first charging stage, applying a second constant current to the battery for a second period of time until a second charging voltage value is reached for the battery to define a second charging stage, and sequentially repeating application of the first and second charging stages to one or more additional batteries such that each of the one or more additional batteries enters the first charging stage when a previous battery in the first charging stage transitions to the second charging stage, and the each of the one or more additional batteries transitions to the second charging stage upon completing the first charging stage until all of the battery and the one or more additional batteries achieve a desired state of charge.

Abstract: Reducing false negatives and finding new classes in object detectors is disclosed. Also disclosed is a method that includes grouping together a plurality of cropped image portions from region proposals based on image properties. The method also includes receiving first user input that either establishes that the grouped together, cropped image portions relate to uninteresting objects or establishes that the grouped together, cropped image portions relate to an object class of interesting objects. The method also includes obtaining, only when the grouped together, cropped image portions relate to the object class of interesting objects, second user input that includes an object label corresponding to the object class of interesting objects.

Abstract: A method for performing an appearance search using a map involves receiving search commencement input requesting that an appearance search for one or more objects-of-interest commence be performed. In response to the search commencement input, one or more video recordings for the one or more objects-of-interest are searched. In conjunction with a map on a display, one or more appearance search results depicting the one or more objects-of-interest are then displayed. Each of the appearance search results depicts the one or more objects-of-interest as captured by a camera at a time during the one or more video recordings, and is depicted in conjunction with the map at a location indicative of a geographical location of the camera. The method may be performed using a video surveillance system and stored on one or more computer-readable media for execution using that system.

Abstract: An apparatus and method for adjusting the height of a vehicle head restraint includes a top cover, latch assembly, and bottom cover. The top cover is connected to the head restraint. A latch assembly is moveable in a lateral direction relative to a latch post, and a bottom cover connects to the top cover, sandwiching the latch assembly between the top and bottom covers. When the button portion of the latch assembly is actuated, the latch assembly unlatches from the latch post, allowing the height of the head restraint to be adjusted. By directly connecting to the underside of the head restraint, the apparatus is further operative to close out the bottom closeout opening on the underside of the head restraint and provide an aesthetically pleasing finish.
