A modular lift system may include, but is not limited to: one or more lift segments each including: a lift-truss structure; and a drive shaft having at least one end-coupler, at least one lift assembly coupled to the lift-truss structure, and at least one drive segment including: a drive-truss structure; a drive motor coupled to the drive-truss structure; and a drive-coupler attached to the drive motor and configured to engage the end-coupler of the drive shaft.

A lifting cabinet includes a transmission assembly and a power unit for raising and lowering a shelf. The transmission assembly comprises a first transmission unit, comprising a screw rod which is connected with a driving device and a sliding piece which is connected with the lifting shelf, and the sliding piece is coupled to the screw rod. The screw rod rotates under the action of the driving device and drives the sliding piece to move back and forth along the axis of the screw rod; and then the sliding piece drives the lifting shelf to move up and down. For the lifting cabinet and the power unit thereof, the transmission assembly converts a rotary motion outputted from the driving device into a linear motion through the cooperation between the screw rod and the sliding piece, and a greater axial force is thereby outputted. Thus, a relatively small motor with a lower output torque can be used in the lifting cabinet to drive a lifting shelf of the same weight when compared to the conventional lifting cabinet, and the problem of large motor in conventional lifting cabinet taking up too much space is thereby solved.

A robot system for maintenance of a building façade with an irregular façade surface is provided. The robot system includes a platform cooperating with a least four pairs of cables for positioning the platform at a distance from a building façade. At least one robot arm is situated on the platform, and includes an adaptor positioned at a distal end thereof for holding and manipulating a building façade maintenance tool. An actuator drives the cables to move the platform to any arbitrary position along the building façade. A controller cooperates with the actuator to instruct the actuator to drive the cables and to control movement of the robot arm, such that driving the actuator and movement of the robot arm is coordinated by the controller; any position deviations in the platform are compensated for by positioning or movement of the robot arm.

A bug-catching curtain system includes a plurality of curtains composed of adhesive material suspended from rigid framing material. A drive shaft is supported by the support structure. A plurality of primary cables extending out from a plurality of spindles that are mounted on the drive shaft. A plurality of support cables are attached to the primary cable and to the rigid framing material. The plurality of support cables suspend the plurality of curtains between rows of plants. A height at which the plurality of curtains are suspended is varied by using the turning the drive shaft to let out and to wind in the plurality of primary cables.

A barbecue cooking apparatus is an apparatus used to cook food items by utilizing different barbecue smoking methods. The apparatus includes a barrel, a lid, a frame, a shelved cooking system, a venting system, a winch mechanism, a lip, and a firebox gasket. The barrel provides a thermal enclosure for cooking the food items. The lid serves to close the barrel and to support the shelved cooking system. The lip and the firebox gasket seal the lid on the barrel when closed. The shelved cooking system holds both the food items within the barrel during the cooking process and the fuel source utilized to generate the heat energy to cook the food items. The frame holds the winch mechanism offset from the barrel. The winch mechanism facilitates the retrieval of the shelved cooking system from the barrel as well as the reintroduction of the shelved cooking system into the barrel.
