Abstract: Systems and methods for deploying emergency roadside signaling devices are disclosed. In one aspect, system for an autonomous vehicle includes one or more signaling devices configured to visually notify other vehicles when placed on or near a roadway, and an object placing device configured to place the one or more signaling devices. The system further includes a processor and a computer-readable memory in communication with the processor and having stored thereon computer-executable instructions to cause the processor to: determine that the autonomous vehicle has experienced a malfunction, and provide instructions to the object placing device to place the one or more signaling devices on or near the roadway.

Abstract: Systems and methods for deploying emergency roadside signaling devices are disclosed. In one aspect, a control system for an object placing device of an autonomous vehicle includes a processor, and a computer-readable memory in communication with the processor and having stored thereon computer-executable instructions to cause the processor to: receive a signal comprising instructions to activate the object placing device; and provide instructions to the object placing device to place a plurality of signaling devices in accordance with predetermined criteria.

Abstract: A surface cleaning head includes a housing having a front side and back side, a brush roll rotatably mounted to the housing within a suction conduit and having at least a portion proximate the opening of the suction conduit, a leading roller mounted to the housing in front of the brush roll, and a drive mechanism operatively coupled to the brush roll and the leading roller for driving the brush roll and the leading roller at same time. The brush roll includes an agitator body and a first bristle/flap arrangement comprising a first deformable flap extending from the agitator body and a first bristle strip and/or row of tufts extending from the agitator body and disposed adjacent to the first deformable flap. The first deformable flap is disposed at an aggressive angle and the first bristle strip and/or row of tufts is arranged at a passive angle.

Abstract: A system for installation of sheet pile including a sheet pile installation apparatus having a substantially rigid elongate beam with an upper end and a lower end, and at least one drive finger proximal the lower end of the substantially rigid elongate beam; and a sheet pile having an elongate member with an upper end and a lower end, and a first side and a second side, the first side having a male profile lock and the second side having a female profile lock, the sheet pile further including at least one receiver proximal the lower end for receiving the at least one drive finger of the sheet pile installation apparatus.

Abstract: An improved bicycle support frame structure for use in bicycles wherein the support frame structure comprises U-shaped channel members serving as load bearing elements and also cooperating with side panels to form a storage compartment for carrying baggage. The storage compartment is accessible through suitable access openings in the side panels, and the space within the compartment may be subdivided by internal brace members which also support and stiffen the side panels.

Abstract: 1. An apparatus for preselecting the Doppler frequency response of a proxty fuze comprising, in combination, radar means for determining the relative velocity between a selected target and a proximity fuze and for developing a predetermined control current correlative to this information, tunable amplifier means in the proximity fuze discretely responsive to said control current and adapted to render the proximity fuze selectively responsive to the determined relative velocity between the selected target and the proximity fuze, a conductive sleeve on the proximity fuze electrically connected to said tunable amplifier, and contact means detachably abutting said sleeve and electrically connected to said radar means for applying said control current to the fuze prior to the firing thereof at the selected target.

Abstract: An apparatus and method for determining the range and bearing of an object rom a reference position. Sound energy emanating from the object and travelling through a water medium strikes spaced hydrophones located at the reference position. The signals produced in each hydrophone are correlated with the signals in each of the remaining hydrophones. The signals are correlated with a variable time delay between signals and the resulting maximum correlation output determines the range and bearing of the object.
