Abstract: Pain can be relieved by passing a bar of elemental sulfur over a painful area. The bar can be of any size or dimension and can be rolled or rubbed across the painful area. The bar can be comprised completely of elemental sulfur, be coated with elemental sulfur, or have an inner layer of elemental sulfur.

Abstract: Magnetometry and pulsed electromagnetic radiation (EM) may be employed during a same survey pass by synchronously interleaving the collection of magnetometer data with pulses from EM sensors. For example, one or more magnetometers may be sampled between pulses of one or more EM coils such that the data from the one or more magnetometers is substantially free of artifacts from the pulsed EM radiation. A detection system may include a vehicle capable of locomotion over a surface of earth, a mount coupled to the vehicle, the mount including at least one magnetometer, at least one EM sensor adapted to produce pulses of EM radiation, and a controller adapted to interleave collection of data from the at least one magnetometer between the pulses of EM radiation.

Abstract: A method and apparatus for resolving a radar return by an object or layer below the earth's surface from a radar return of an air-to-earth interface. More specifically, a method and apparatus for generating short pulsewidth, broad bandwidth RF signals and for effecting control and timing of transmitted and received radar signals in order to focus an antenna illumination pattern. The apparatus includes an antenna array including a plurality of antenna elements which transmit and receive the RF pulsed signals and a custom control module which generates the control signals fed to the antenna array to delay the RF pulse signals with respect to each other, upon transmission and receipt, in order to form transmit and receive antenna illumination patterns.

Abstract: Method and apparatus are disclosed for advancing and retracting a torque applying tool to and from an operative position. The disclosed apparatus, which includes a push button retracting mechanism, includes structure for transmission of bidirectional torque between its housing and the tool. Screwdrivers and other torque applying tools may thus be driven by rotation of the apparatus housing.
