International Classification:

B62D 57/02
E21B 43/00

US Classification:

180 71, 180 81, 180 85, 180 9, 180 21, 180313, 166 66, 166 50, 166 55, 299 31, 305 60, 305404

Abstract:

A self-propelled mechanical crawler adapted to move on a medium. One example of such a crawler includes a foot, a wave generator adapted to drive a periodic wave in the foot, and a wave transfer mechanism coupled between the wave generator and the foot. The wave transfer mechanism may be adapted to translate the periodic wave produced by the wave generator into a corresponding periodic deformation in the foot so as to generate forces in the medium to propel the crawler.

International Classification:

G06F 15/16

US Classification:

709204

Abstract:

Apparatus having corresponding methods and computer-readable media comprises an input circuit to receive registration messages from virtual meeting servers, wherein each registration message comprises a network address of the respective virtual meeting server and an identification string for the respective virtual meeting server; a memory to store an association for each of the virtual meeting servers between the respective network addresses and the respective identification strings; wherein the input circuit receives virtual meeting invitation acceptance messages each comprising one of the identification strings; a processor to select the network addresses associated with the identification strings in the virtual meeting invitation acceptance messages; and an output circuit to transmit a redirect message in response to each of the virtual meeting invitation acceptance messages, wherein each of the redirect messages comprises the network address associated with the identification string in the corresponding virtual meeting invitation acceptance message.

Inventors:

Brian Chan - Castro Valley CA, US
Steve Nelson - San Jose CA, US
Victor Ivashin - Danville CA, US

International Classification:

G06F 7/04

US Classification:

726 28

Abstract:

Apparatus having corresponding methods and computer-readable media comprise an input circuit to receive, from a license management server, a check-in sequence representing a plurality of different check-in times; a processor to execute a software product comprising an application, and a client license management module to add timestamps to a check-in record at the check-in times; and an output circuit to transmit the check-in record to the license management server; wherein the license management server performs a comparison between the check-in record and at least one of the check-in sequence, and an earlier check-in record previously sent by the client license management module to the license management server; and wherein the license management server transmits a violation message to the client license management module when the comparison fails; and wherein the client license management module disables the application based on the violation message.

Abstract:

The described embodiments concern one or more methods, systems, apparatuses, and computer readable mediums storing processor-executable process steps to authenticate mobile subscribers for using a foreign application when they are outside of their home telecom carrier's mobile network zone (“foreign zone”). A mobile subscriber can be authenticated through data roaming service, voice roaming service, and/or WiFi service. After cross network authentication, a mobile subscriber can use the foreign application to provide the same or similar services in a foreign zone, such as foreign country, through the home services in connection with the subscriber's home telecom carrier in a similar manner like he/she can use in his/her home zone, such as home country.
