Abstract: A device for employing sonic transmissions is utilized to determine fluid level in a well or a container. The device may be utilized while the well is operating. It is known that wells replenish fluid at different rates even in the same formation or well field. Increased well production at minimum pumping cost is achieved for a given well. The device generates a sonic event through the use of a compressed fluid that is obtained from within a well. A fluid level measurement system is obtained in a well in which gas is produced under vacuum.

Abstract: A tool for use in well monitoring is described to insert devices for well fluid level control into a wellhead. The tool also permits removal of the devices for well fluid level control from an operating well for servicing. The tool also permits precise positioning of the components utilized to take measurements in the well annulus.

Abstract: Tracking devices are provided that use wireless local area networks to determine location. The tracking devices receive identification data from at least one local are network in the vicinity of the tracking device, and store tracking data that includes the identification data as well as a date and time stamp indicating when the identification data was received. The devices can transmit the tracking data to a server, and the location of the tracking device can be determined using the tracking data.

Abstract: A portable monitoring apparatus includes a bracelet having a housing and a strap for connecting the bracelet with a body part of a person being monitored, and an electronic monitoring circuit disposed in the housing. The electronic monitoring circuit executes an executable program for controlling the monitoring circuit according to a control algorithm. The executable program is modifiable by over the air programming from a monitoring network having transmitting and receiving circuits in operative communication with the electronic monitoring circuit. The housing of the bracelet includes a contract portion configured to engage the skin of the person being monitored and a cavity portion having an opening defining a closed sampling volume when the base is in contact with the person. An alcohol sensor is disposed at the sampling volume for detecting a physiological condition of the human and generating a signal thereof.

Abstract: A method of using a variety of sonic transmissions is utilized to determined fluid level in a well. It is known that wells replenish fluid at different rates even in the same formation or well field. The fluid levers, which may be determined include water and petroleum. The sonic signals may be transmitted through the annulus in a well where the medium is a gas such as methane. The sonic signals may be also be transmitted through the casing or tubing of the well, which is typically steel pipe. Signals are generated, reflected, received, and converted into data. The data is then utilized to determine an initial liquid level P2, a no liquid pumpable state P0, and to activate the pump to pump the liquid, and inactivate the pump at a liquid level P1 above the no liquid pumpable state P0. [Maximum production at minimum pumping cost is achieved for a given well.
