Abstract: A method of creating fees or other revenue for vehicle display users who own or lease display and portable transmitting/receiving equipment. A party running an advertising server transmits and receives communications from the portable transmitter/receiver. The transmitter/receiver functions both to select and display advertisements and offers but also to display emergency and missing children alerts that are received through the emergency broadcast system. Vehicle display users may also generate their own local ads and offers. Responders to the advertisements and offers participate by downloading an app from their cell phone app store that allows them to receive messages when the potential responder are in the vicinity of the vehicle user advertising display. The advertising server records activity generated by vehicle user displays and collects revenue from advertising sources and distributes revenue to the vehicle display user.

Abstract: Various methods, systems, and computer program products are disclosed for determining a location estimate of user equipment in a mobile network. For example, a method may include receiving measurement data that includes a time of arrival indication of data communicated between the user equipment and base stations of the mobile network. The method may further include processing only the received measurement data that is within a particular time window and excluding some of the received measurement data outside the particular time window. The method may further include determining a sync value based on the received measurement data within the time window. The sync value may synchronize timing between at least two base stations of the mobile network. The method may include determining a location of the user equipment based on the sync value and the measurement data. The method may include geometric or linear optimization of the determined location estimate.

Abstract: A process of manufacturing a drive shaft of an explosion-proof motor, the drive shaft having a cylindrical section and a spline section, the process includes the steps of horizontally disposing the drive shaft; continuously forward moving the drive shaft; feeding both a milling cutter and a correction roller toward the drive shaft wherein the correction roller is coaxial with a shaft of a lathe; activating the milling cutter to mill a front end of the drive shaft; and activating the correction roller to correct any deformations generated by the milling. The correction roller is made of diamond. The cylindrical section has a deformation of less than 0.02 mm per 200 mm of length, and the spline section has a deformation of less than 0.02 mm per 250 mm of length.

Abstract: A process of manufacturing a feed screw includes the steps of arranging three dies spaced apart 120-degree each other so as to limit a radial movement of an elongated blank feeding through a space defined by the dies; clockwise rotating the dies to cut threads on the blank; performing a thread grinding on the threads of the blank; and cutting the blank into a finished feed screw per predetermined period of time. The blank is fed through a sleeve for positioning prior to the blank feeding. Cylindrical degree of the finished feed screw is less than 0.1 mm/1,000 mm and its pitch error is 0.05 mm/100 threads.

Abstract: A device is described that may be positioned at a location in an intervertebral disc for diagnosis or treatment of the disc. Treatment may include, for example, applying energy or removing material, and may decrease intradiscal pressure. Radiofrequency energy may be applied. A percutaneous method of repairing a fissure in the annulus pulposus comprises placing an energy source adjacent to the fissure and providing sufficient energy to the fissure to raise the temperature to at least about 45-70° C. and for a sufficient time to cause the collagen to weld. An intervertebral fissure also can be treated by placing a catheter with a lumen adjacent to the fissure and injecting sealant into the fissure via the catheter, thereby sealing the fissure. An intervertebral fissure additionally can be treated by providing a catheter having a distal end, a proximal end, a longitudinal axis, and an intradiscal section at the catheter's distal end on which there is at least one functional element.
