An engine, e.g., a cam drive, barrel-type internal combustion engine, that includes: a main drive shaft defining a longitudinal axis; a sinusoidal main drive cam rigidly attached to the main drive shaft; a plurality of cam members that are in contact with the sinusoidal main drive cam and that are configured to follow the sinusoidal main drive cam, wherein rotation of the sinusoidal main drive cam corresponds to reciprocating linear movement of each of the plurality of cam members in a direction parallel to the longitudinal axis; for each cam member, a pair of linear pistons disposed on opposite sides of the cam member for reciprocating linear movement within respective cylinder bores.

摘要:
The present invention pertains to enhancement or refinement of estimated locations based upon user-specific information. Upon user authorization, geographical information is extracted from a number of user-related sources, including the web browser history, search history, maps history, address book, e-mail archives and calendar entries. Such information is used to build a spatial index of specific physical locations for a geocoded result set. From this, heat maps identifying particular locations from the user-related sources are created for different periods of time. The heat maps may be used to refine an initial location estimate of the user. This may be done by determining whether one or more positions in a given heat map provide a more accurate position of the user than the initial estimate. If so, a best position is selected. This can be used to provide enhanced driving directions to the user.

An alert server is operative to notify users when they are in proximity within one another. The alert server may determine to alert a first user of the proximity of a second user when the second user is in an unusual location. The alert server may determine that the second user is in an unusual location when the second user is outside his or her routine geographic location. The alert server may determine whether the second user is outside his or her routine geographic location by assigning confidence values to geographic locations that the second user has previously visited. The alert sent to the first user may be in the form of a text message, e-mail, or other electronic communication. The first user may receive the alert on a mobile device, such as a cellphone, smartphone, netbook, or other mobile device.
摘要:
A system and method is disclosed for requesting an updated location, including a point of interest, from a user for display on an interactive map. On receiving from an interested user a request for a point of interest associated with a subscribed user's current location, a request is transmitted to the subscribed user to check-in to the point of interest. In response to the request, the subscribed user selects a selected point of interest from a selection list. A representation of the subscribed user and the selected point of interest is then provided for display on an interactive map associated with the interested user.

Systems and methods are provided for creating and using personalized location information tags (geotags). Personalized geotags take the place of generic location information such as latitude/longitude coordinates or granular city/state information. Such geotags may be published to present to selected people, e.g., family and friends, a user's current location. Thus, the user's location may be shown as “Home” or “Gym,” providing user-specific information without having to list a street address or latitude/longitude coordinates. Personalized geotags may be inferred based upon historical location information of the user. Geotags may also be inferred based upon geotag selections from other users in a network. A matching engine may select an appropriate geotag given the current location of a user device or based upon historical location information associated with the user.
