Abstract: The shape and size of a borehole may be characterized downhole, using measurements of the borehole shape in conjunction with a catalog of shapes against which the measured shape is matched. A unique identifier for the measured borehole shape, and optionally a size parameter, may be transmitted to a surface facility, generally saving bandwidth compared with the transmission of the raw measured borehole-shape data. Alternatively or additionally, downhole measurements may be adjusted based on the measured shape.

Abstract: The exercise performance monitoring apparatus consists of gloves and shoes that have embedded pressure sensor arrays to measure pressure applied to them during exercise. The gloves and shoes send the pressure data using wireless RF transmitters to a central display control unit located on each glove. The gloves have color LED strips which change color depending on whether the gloves or shoes are measuring equal pressures. The glove displays the state of balance between the glove and shoe pressures using separate LED displays on each glove. The pressure balance is adjustable as well as the selection of colors to display. The user can at a glance see if he or she is in balance when performing the specific exercise by observing the color shown on the glove display. The glove display for either glove or shoe pressure will flash the color representing unbalanced pressures if the pressures are unbalanced on the glove having the highest or lowest pressure depending on user preference.

Embodiments of the EM telemetry system with capacitive electrodes include a downhole transceiver comprising an encoded signal transmitter, a downhole sensor disposed to monitor the downhole equipment, and an encoded signal receiver comprising one or more capacitive counter electrodes. The one or more capacitive counter electrodes receives a first encoded signal from the downhole transceiver, the encoded signal corresponding to a voltage measured between the counter electrode and a wellhead. A decoder and demodulator of the encoded signal receiver recovers information in the first encoded signal. A second encoded signal, which may include instructions for the downhole equipment, may be similarly encoded, modulated, and transmitted from the encoded signal receiver to the downhole transceiver.
