Abstract: An apparatus for precisely measuring and applying torque and angle of rotation to tighten screwed fasteners. The apparatus includes a drive motor for generating a rotation, a pair of spaced triggers for activating the operation of the drive motor, and a controller for precisely measuring the torque to be applied and angle of rotation to be achieved by the apparatus, the controller not permitting the motor to be activated without both of the triggers being activated. A reduction gear system is also provided for reducing a rate of rotation generated by the motor, the reduction gear system outputting a rotational drive torque for driving the screwed fastener.

Abstract: A coverage robot including a chassis, multiple drive wheel assemblies disposed on the chassis, and a cleaning assembly carried by the chassis. Each drive wheel assembly including a drive wheel assembly housing, a wheel rotatably coupled to the housing, and a wheel drive motor carried by the drive wheel assembly housing and operable to drive the wheel. The cleaning assembly including a cleaning assembly housing, a cleaning head rotatably coupled to the cleaning assembly housing, and a cleaning drive motor carried by cleaning assembly housing and operable to drive the cleaning head. The wheel assemblies and the cleaning assembly are each separately and independently removable from respective receptacles of the chassis as complete units.

Abstract: A web page may be rendered for display on a client device. The rendered web page may be based on a first document. It may be determined that (i) a scroll position of the rendered web page has changed such that the scroll position is below a threshold scroll position, and (ii) the change of the scroll position is due to an event other than receiving a scrolling command from a user. Possibly responsive to this determination, a second document may be requested and received from a content server device. The web page may be re-rendered for display on the client device. The re-rendered web page may include content from the first document and content from the second document.

Abstract: A web page may be rendered for display on a client device. The rendered web page may be based on a first document. A first scroll position of the rendered web page may be determined. The first scroll position may be below the beginning of the first document. The web page may be re-rendered for display on the client device. The re-rendered web page may be based on a second document. A web-page navigation back command may be received. Possibly responsive to receiving the web-page navigation back command, the web page may be further re-rendered for display on the client device, and a scroll position of the further re-rendered web page may be adjusted to be at the beginning of the first document. The further re-rendered web page may be based on the first document.

Abstract: A first document may be requested and received from a server device. Based on the first document, a web page may be rendered for display on a client device. The rendered web page may include a plurality of selectable items, each corresponding to a respective type of web page content. Via a user interface of the client device, a selection of a first selectable item of the selectable items may be received. Possibly responsive to receiving the selection of the first selectable item, a second document may be requested and received from the server device. The second document may include a first particular type of web page content corresponding to the first selectable item. The web page may be re-rendered for display on the client device to include content from both the first document and the second document.
