Organosilane condensates are described as well as their use in coating compositions, processes for making them and process for applying the coating compositions. The organosilane condensates can be formed from the hydrolysis of at least one medium to long chain trialkoxy silane compound, an amino silane and optionally one or more additional reactants. Coating compositions containing the organosilane condensates can provide coatings having improved scratch and mar resistance and can have excellent recoat adhesion.

Systems and methods are presented to support operation of a multiple subscriber identity module (SIM) device. A first SIM may perform a data transfer or voice call. During the first SIM's data transfer or voice call, transition times are identified to transition communication resources to a second SIM for use in performing a registration update communication with a network controller that supports the second SIM. The registration update communication may include a periodic location update, a periodic routing update, or a periodic tracking update. The multiple SIM device may identify the transition time by obtaining periodic registration timing information from the network controller, configuring a periodic registration timer based on the periodic registration timing information, and setting the transition time as an expiration time of the periodic registration timer.

A variable configuration articulated tracked vehicle comprises a chassis, a pair of right and left drive pulleys, a right and left planetary wheel, a right and left track, a right and left arm mechanism, and a right and left drive motor. The drive pulleys are rotatably attached to the chassis and each pair of drive pulleys is in the same plane. The planetary wheels are movable relative to the chassis such that each planetary wheel is in the same plane as its respective drive pulleys. The tracks extend around the pair of drive pulleys and the planetary wheel on the respective sides. The arm mechanisms connect the respective planetary wheel to the chassis. Each arm mechanism is rotatably attached to the chassis with a cam. The cam defines a motion path of one end of the arm whereby the motion of the planetary wheel provides a path for the planetary wheel such that the track path defined by the respective drive pulleys and the planetary wheel is a constant track length. The motors are each operably connected to the respective pair of drive pulleys for driving the track.
