A snow removal machine capable of illuminating, with a light projector, a dropped position of snow that varies depending on a direction of a chute guide. A working machine as a snow removal machine includes a machine body, and a chute that is provided on the machine body, and throws away snow. The chute includes a chute main body extending upwardly from the machine body, and a chute guide that is pivotably provided on a distal end portion of the chute main body, and adjusts a snow throwing direction that is an up-down direction of the snow to be thrown, the chute guide is connected to the chute main body side through a link, and the link is provided with a light projector so as to be capable of illuminating a dropped position of the snow to be thrown.

A system for dredging a seabed includes a trailing suction hopper dredger. The trailing suction hopper dredger includes a hull, a rail coupled to the hull, and a dredge arm coupled to the rail. The dredge arm includes an upper suction pipe coupled to a lower suction pipe. A pump is coupled to the upper suction pipe and is configured to draw material toward the upper suction pipe from the seabed. A visual marine life deterrent is coupled to the dredge arm and is configured to direct light toward the sea floor where marine life may be located. Another visual marine life deterrent includes a silhouette of a marine life predator. The visual marine life deterrents are configured to be observable by the marine life and cause marine life to move away from the dredge arm.

A shovel includes a lower traveling body, an upper turning body turnably mounted on the lower traveling body, a cab mounted on the upper turning body, multiple image capturing devices mounted on the upper turning body, a display device provided in the cab, and an operation part provided in the cab. The display device includes an image display part configured to display a captured image captured by at least one of the image capturing devices and a menu screen. The image display part is configured to display the menu screen while displaying the captured image, in response to the operation part being operated.

A working spotlight for a vehicle is provided, featuring a housing, a light source, and a light guide system for guiding working light generated by the light source in a predefined direction out of the housing and into a working area. In and/or on the housing, a means of generating a motif is arranged for projecting at least one motif onto a projection surface outside of the housing.

Provided is an LED lamp for prevention of freezing, comprising: a housing opened at a front side thereof; an LED unit disposed inside the housing; a lens mounted at the opened front side of the housing and configured to allow lighting light emitted from the LED unit to transmit therethrough; a heating member disposed at the rear side of the lens and configured to generate heat by being supplied with power; a sensor unit disposed at the inside of the housing and configured to sense the internal temperature of the housing; and a control unit configured to control the power supplied to the heating member depending on the internal temperature of the housing, sensed by the sensor unit.

A snowplow having a snow removal mechanism, the snowplow comprises: an obtainment unit configured to obtain topography information prior to snow accumulation; and a projection unit configured to, based on the topography information prior to snow accumulation obtained b the obtainment unit, project an image indicating the topography information prior to snow accumulation on a surface of accumulated snow that is to be removed by the snow removal mechanism.

An example system includes a vehicle, a light projector connected to the vehicle, and a control system. The control system is configured to determine a planned operating region for the vehicle within an environment. The control system is also configured to determine that the planned operating region is within a threshold distance of an object within the environment and, in response, determine a caution region to illuminate with the light projector near the object. The control system is further configured to cause the light projector to project an indication of the caution region near the object. The projected indication remains fixed in relation to the object as the vehicle moves toward the planned operating region.

A battery operated trash can carrier (100) for holding and transporting one or more containers is provided. The trash can carrier (100) includes a frame (102) having a laterally facing ramp (106) defining an entry means adapted to slidably receive one or more containers on a platform (104). The trash can carrier (100) includes a wheel base, where the wheel base includes a pair of wheels on one axle (108-1) and another pair of wheels on second axle (108-2). The trash can carrier (100) further includes a detachable power drive (110), battery compartment (130), ramp control (124), electronics control module (126) and a steering control (128). The detachable power drive (110) coupled to the wheel base, to power the pair of wheels on the one of the axle (108-2) and to steer the pair of wheels on the other axle (108-2) to transport carrier from one place to another.

A light assembly for attachment to a surface of a vehicle includes a vehicle base configured to be coupled to the surface of the vehicle, and a light head coupled to the vehicle base and including a plurality of light emitting diodes and a lens. The lens has a plurality of total internal reflection lenses. Each total internal reflection lens has a truncated frustoconical cross-sectional shape.

A burden on an operation of an operator is reduced. A working machine includes a grid light that projects a grid light of a grid-shaped pattern, and a control unit that control the vehicle in accordance with deformation of the pattern of the grid light according to a shape of a projection spot.
