Abstract: Circuits, methods, and apparatus that provide user interfaces for playing games on portable electronic devices. One example provides a game accessory having input controls for playing video, audio, and other types of games. The game accessory can have input controls, such as buttons, joysticks, and D-pads. Another example provides a game accessory having a thumb pad or keyboard. Other possible features include microphones, cameras and camera lenses, speakers, a second screen, rumble, and motion detection. The game accessory may have a recess sized to fit the portable electronic device. Inserts or removable adapters can be used to fit portable electronic devices having different sizes. The portable electronic device can be held in the accessory using sliding covers, clips, or other engaging members. In other examples, the accessory can communicate with another accessory for head-to-head game play. The accessory may include circuitry for power, identification, and authorization.

Abstract: Improved approaches to provide user interaction with a portable electronic device operating to in a particular mode, such as an e-reader mode, are disclosed. In one embodiment, the portable electronic device is a multi-function portable electronic device that can be configured differently based on a particular mode being used. Based on the mode of operation or application being used, the user inputs to the device can be characterized differently. Advantageously, with mode-based configurations, the portable electronic device can operate to make use of user interface controls in an efficient manner. The mode-based configuration can save power, increase efficiency, and/or speed up operation of the device.

Abstract: Mantle lifting device (10) has a body (26) configured to selectively engage and disengage an opening (24) of a mantle (12) by rotation in respective opposite directions about a central axis (28) of the body (26). The body (26) is provided with a lifting point (30) which is configured to couple with a lifting device such as a crane (not shown). The body (26) is in the general form of a plug having an upper surface (34) and an opposite surface (36) and tapered circumferential surfaces (38 and 40). The surface (40) is provided with indicia (43) commencing at a distance d on the surface (40) below the edge (42). This is used to indicate safe or unsafe lifting conditions. The indicia (43) being visible when the device (10) is engaged with the mantle (12) is an indication that the mantle (12) is worn to the extent that it may not be safe to lift the mantle (12) by way of the device (10), or at least not without additional safety precautions being taken.

Abstract: An estimated travel time for a route generated by a navigation system can be modified using a route-specific, custom travel factor computed from data collected by the navigation system while the user is traveling the route. In one aspect, the data can be stored in a local or remote database accessible by the navigation system. The data can be used to classify routes so that custom travel factors computed for a route in a given class can be used to estimate travel times for other routes in the same class. In another aspect, the classified custom travel factors can be shared with other users.

The indicia (43) being visible when the device (10) is engaged with the mantle (12) is an indication that the mantle (12) is worn to the extent that it may not be safe to lift the mantle (12) by way of the device (10), or at least not without additional safety precautions being taken.

Abstract: A jaw assembly for a jaw crusher is disclosed where the assembly comprises a jaw stock (12), a wear plate (16), and a fastening device in the form of a bolt (34) with a square head (42) at one end and a washer (56) and fastening nut (52) positioned at an end opposite to the one end. The bolt (34) extends between the jaw stock (12) and the wear plate (16). The fastening device (34, 42, 56, 52) is operative to adopt a clamped configuration where the device provides a clamping force along a fastening axis to clamp the wear plate (16) at the jaw stock (12), and a released configuration where the fastening device does not prevent the wear plate (16) from being separated from the jaw stock (12). The fastening device (34, 42, 56, 52) is accessible from a direction that is transverse to that fastening axis, to enable the device (34, 42, 56, 52) to be changed from its clamped configuration to its released configuration.

Abstract: A bail support and a top drive system for an oilfield drill rig. The top drive system includes a drive apparatus, and the bails have bodies with upper head portions and two spaced-apart legs. Each leg includes an upper leg portion and a lower leg portion. The upper leg portions are non-parallel to each other and extend from the head portion at an angle to a centerline of the bail. Each lower leg portion extends down from its corresponding upper leg portion in a reverse bend.
