Abstract: A system includes a first interface module and a route determining module. The first interface module interfaces with a scheduling program and retrieves from the scheduling program a meeting time and a meeting location for a meeting scheduled by a user using the scheduling program. The route determining module determines (i) a route from a first location to the meeting location and (ii) a departure time for the user to depart from the first location to reach the meeting location at the meeting time. The route determining module determines the route and the departure time based on (i) predicted traffic conditions and (ii) predicted weather conditions surrounding the first location and the meeting location prior to the meeting time.

Abstract: A planetary gearset is provided having an internal ring gear with a plurality of generally radially inwardly extending teeth in meshing engagement with at least one pinion gear. A hub portion extends generally radially inwardly from the internal ring gear. The internal ring gear and the hub portion are integrally formed. Additionally, the internal ring gear and hub portion may be integrally formed by one of a spinning operation, powdered metal compaction, and cold extrusion.

Abstract: A planet carrier assembly has a plurality of pinion gears rotatably mounted on pinion pins, each pin having a slot formed thereon. A locator ring is assembled onto the pinion pins and rotated in a manner such that the locator ring engages the slots in the pinion pins and a plurality of tabs and protuberances engage complementary components formed on a housing member of the planet carrier assembly. The locator ring ensures both axial and rotational positioning of the pinion pins within the planet carrier housing.

Abstract: A hybrid transmission including two electric motors and a plurality of planetary gear sets operatively connectable to the motors and to an engine is provided. Novel motor features are provided including structure adapted to improve reliability and to facilitate assembly. More precisely, a method is provided for locating and installing the components of a motor, including a rotor and a stator, within a covered housing to form a motor module. A plurality of rotor bearings and a position/speed sensor are also preferably added to the motor module. After the motor module is assembled, the motor may be tested and thereafter the motor module can be installed into a hybrid transmission as a single component utilizing conventional transmission assembly methods.

Abstract: The present invention is a sports implement for hitting a pitched object. The sports implement includes attachments for a contact end of the implement allowing variation of the weight and/or length of the sports implement.
