    Abstract: A sonde includes an elongate flexible ferromagnetic core and a coil surrounds an intermediate segment of the core. A housing surrounds and supports the coil. An electronic drive circuit is mounted in the housing for supplying the coil with an electric signal that will induce the core to emit electromagnetic signals at a predetermined strength and frequency that can be remotely detected. Self-contained battery powered float-type and pill-type sondes are also disclosed.

    Abstract: A weight belt which a diver can release quickly and swing free and clear of the diver's legs and gear with one hand in case of an emergency. The ends of a waist encircling piece of webbing are threaded through corresponding male and female parts of a buckle. The male part has a transversely extending hook formed at a forward end thereof. The female part has a transversely extending post at a forward end thereof and a transversely extending hook receiving cavity. The hook can be inserted into the cavity to engage and surround the post when the male and female parts of the buckle extend substantially at a right angle relative to one another. The male and female parts can thereafter be rotated so that they are in substantial longitudinal alignment and lie flat against the diver's body. The male and female parts cannot more transversely or longitudinally with respect to each other in this alignment. A release knob may be pulled with one hand to rotate the male part of the buckle through a sufficient angle relative to the female part so that the parts will disengage.

    Abstract translation: 潜水员在发生紧急情况时，一只手能够快速释放并摆脱潜水员的腿部和脚部的重量皮带。 腰围环绕的织带的端部穿过带扣的相应的公和母部分。 阳部件在其前端形成有横向延伸的钩。 阴部分在其前端具有横向延伸的柱，横向延伸的钩接收腔。 当扣环的阳和阴部分基本相对于彼此成直角地延伸时，钩可以插入空腔中以接合和围绕柱。 此后，男性和女性部分可以旋转，使得它们基本上纵向对准并且平躺在潜水员的身体上。 在该对准中，阳部件和阴部件不能相对于彼此横向或纵向。 可以用一只手拉动释放旋钮，以使扣环的凸形部分相对于凹形部分旋转足够的角度，使得这些部件将脱开。

    Abstract: Location systems and methods for locating paint and other markings on a surface are described. More specifically, but not exclusively, the disclosure relates to smart paint stick devices and methods of use in locating and marking buried utility lines or other buried objects. One system for locating a buried object may include a buried object locator and a paint stick. The locator may include a tracking component configured to detect a location of a buried object. The paint stick may be configured to cause a paint container to dispense paint at a first position associated with the location of the buried object. The paint stick may include a position determination component configured to transmit one or more range vector signals that are detected by the tracking component. Sensors may be used to determine when paint is dispensed from a paint container, and to determine a color of the paint or a type of a marking.
