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.

A device that can hold at least two cans of spray paint or chalk, thus enabling marking with different colors using a single device. The device comprises a staff, a can holster, a grip, a trigger and a selector. The selector comprises a selector rod moveable in or alongside the staff. At one end of the selector rod is a selector knob and at the other is an engagement mechanism that engages the spray valve of each can, one can at a time. The engagement mechanism comprises a cam and a rocker arm with two opposing fingers, one to engage each spray can when selected. Optionally one or more flag holders may be attached to the staff for holding marker flags.

A soil compactor for compacting soil material, in particular asphalt, comprises at least one compactor roller (14, 16) which is rotatable on a compactor structure (30) around a roller axis of rotation (W) which is essentially orthogonal to a compactor longitudinal direction (L) and at least one marking unit (26, 26) carried on the compactor structure (30) for applying marking material (M) to soil material (12) driven over by the soil compactor (10).

Concepts and technologies are disclosed herein for an antenna placement determination device. An antenna placement determination device can include a signal sensor located at a first end of an extendible arm, a platform located proximate to a second end of the extendible arm, a drive system connected to the platform, and an actuator connected to the extendible arm. The actuator can be configured to extend and collapse the extendible arm. The signal sensor can be connected to the extendible arm by a joint, and a sensor actuator or sensor motor can rotate the signal sensor about the joint. The drive system can include a drive motor and a drive mechanism that is configured to transport the antenna placement determination device.

A tool for marking the location of a bonding plate concealed beneath a roof membrane. The tool has a magnetic attraction to the bonding plate and causes a marking assembly to vertically lower toward the roof membrane and rotate on an axle. Rotation of the marking assembly and vertical lowering causes the marking implement to come into contact with the roof membrane at a location corresponding to the location of the bonding plate beneath the roof membrane. A brake restricts the rotation of the marking assembly on the axle by coming into contact with an inner edge of a chassis. Contact between the marking implement and the roof membrane and the restriction of rotation of the marking assembly by the brake cause the marking implement to create a visible mark at a position corresponding to the location of the bonding plate beneath the roof membrane.

An intelligent marking paint applicator system and method of use. The applicator, such as a marking stick or gun for example, can include a composition marking applicator and associated electrical and electronic components mounted in or in association with the device to identify and record composition (such as spray paint for example) marking activity. The device may optionally include GPS locating sensing capability to identify the location of the composition marking activity. The device may optionally provide marking activity to one or more separate devices, including in order to identify the location of the composition marking activity. Some embodiments of the applicator can also be lightweight, compact, and economicalin some embodiments, relying on use of the device with one or more other separate smart devices to provide geolocation of device for example.
