Abstract: A short-range wireless network is established by direct communication between wireless devices and wireless access points. A wireless communication device provides initial registration information to a network and becomes a registered device. An API is downloaded to the wireless device to permit automatic authentication of the device for future communications. When a registered device enters a venue, at least one access point will automatically detect the wireless device and extract the necessary identification data to permit authentication of the device. Customized messages may be provided to the wireless device. If the wireless device enters a different venue, even in another city or state, the registration data may be automatically extracted by an AP and provided to a cloud network for authentication. Authenticated devices receive a list of authenticated vendors and unauthenticated vendors near the present location of the authenticated device.

Abstract: Systems and methods are disclosed for obtaining distance related wellbore parameters using pulse-echo measurements. For example, the depth of a wellbore may be computed and/or the length of a tubular string positioned in a wellbore may be determined. In an embodiment, a pulsar is deployed into a wellbore along a length of tubular. Once deployed, a fluid pulse is sent form a surface pulse generator and the transmission time is recorded. The downhole pulsar receives the fluid pulse and, in response, returns a second fluid pulse back to the surface. Surface processing circuitry receives the second fluid pulse and records the reception time. The processing circuitry then process the data to determine the total time for travel, thereby determining the length of the downhole pipe or other tubing.
