In a cable-driven three-dimensional crane system, an end-effector is moved within an operating volume defined by dynamically shifting draw points. Winch assemblies pull the end-effector toward the respective draw points. Each winch assembly includes a cable router that manages travel of its drive cable through the associated draw point. Cable length encoders determine the effective length of each drive cable, from which one method of end-effector position calculations can be made. Draw point angle trackers assess the instantaneous lateral and vertical angles of each drive cable as it vectors away from its draw point toward the carrier from which another method of end-effector position calculations can be made as well as enabling self-calibration techniques. Sensitive mechanical and electrical components are sheltered in heated enclosures that wipe debris from the drive cable and track with its changing position. Multi-zone applications allow sharing of winch assemblies.

An appliance-support system in accordance with the present disclosure includes a truss and a positioning system coupled to the truss. The positioning system is adapted to support an appliance, such as a video display, light, speaker, or other device used during stage performances or events.

It is the objective of the present invention to create additional functional, flexible and accessible work and storage area in the home, office, workshop, automobile, medical and industrial environments by providing means to firmly and securely mount, store and access articles such as appliances (e.g., flat panel video displays/monitors, can openers, weighing scales) and organizing/storage vessels (e.g., spice racks, first aid kits, sewing boxes, knife blocks, tool kits) on downwardly facing surfaces, such as the underside of cabinets and shelves, and on vertical surfaces (such as cabinet doors and frames) and by enhancing access to those articles on horizontal surfaces such as countertops. The invention performs its functions using a small number of readily manufacturable, modular, standardized components. The invention also performs its functions maximizing adjustability, reliability, use of available space and ease and flexibility of installation.

The present invention relates to monitors. In order to facilitate mounting a monitor, a suspendable monitor (10) is provided for a ceiling suspended monitor system. The suspendable monitor comprises a video display (12), a structural frame (14), and a system interface (16). The video display is mounted to a front surface (18) of the structural frame. The system interface is mounted to the structural frame at one end and mountable to the ceiling suspended monitor system at the other end for suspending the suspendable monitor.

A modular bridging system comprises a channel configured to receive a portion of an elongate rail, the channel being configured to receive the elongate rail substantially perpendicularly to a longitudinal axis of the modular bridging system; a rail fastener securing the received rail within the channel; a leg receiver configured to receive an elongate leg section; and a leg fastener securing the received leg section such that the received leg section and the elongate rail are configurable to be temporarily affixed in place in relation to each other, wherein a securing point of the fastener is adjustable along a plurality of points along each leg section.

A belt transmission mechanism with improved rigidity comprises a pedestal, a sliding base, a driving unit, a positioning belt, and a transmission belt. The sliding base is disposed on the pedestal, and reciprocatively moves along a linear direction. The driving unit is disposed on the sliding base. The positioning belt and the transmission belt are disposed on the pedestal and comprise a gear rack, respectively. A detouring section of the transmission belt is separated from the positioning belt, and transmissibly meshed with the driving wheel of the driving unit. When the driving wheel rotates, the detouring section is driven to continuously shift on the transmission belt, and the sliding base is simultaneously driven to slide on the pedestal along the linear direction. Thus, a combination of the positioning belt and the transmission belt achieves an improved rigidity.

A method and device are provided for positioning a mounted camera. The device includes a holding element that secures the mounted camera to the device, a wireless linkage at which remote attitude commands representing attitude changes of a remote driver are received, a local controller that interprets the remote attitude commands and generates local attitude commands that move the camera to mimic an orientation of the remote driver, and an attitude sensing element that senses a local attitude of the device. The attitude sensing element includes a gyro, an accelerometer, or a magnetometer, and jitter present in the remote attitude commands is removed and not passed on to the local attitude commands.

The present disclosure provides a display system and a display device base for mounting a display device. The display device base includes a first horizontal displacement mechanism capable of being displaced along a first horizontal direction; a second horizontal displacement mechanism mounted on the first horizontal displacement mechanism and capable of being displaced along a second horizontal direction perpendicular to the first horizontal direction; and a rotation mechanism rotatably mounted on the second horizontal displacement mechanism and configured to mount the display device.

A rail element (10, 33) for a camera slider system or, more generally, a tube joiner for a rail comprised of an expansion device (23, 30), located internally at an open end (12, 32) of a tubular body (11, 33). The expansion device is configured to fit within a male part or joiner element (16, 31) that may be inserted into the end of the tube (10, 33) and can be actuated to an expanded state where it exerts force radially outwards through the joiner (16, 31) to hold it against the open end (12, 32), thereby joining two tubular or rail element ends together.

Provided are a photographing apparatus, and a control method and device applied to the photographing apparatus. The photographing apparatus comprises a shell (11), an illumination unit (12), a guide rail unit (13) and a control unit (14), wherein the illumination unit (12) comprises a shading plate (122) and an illumination lamp (121), with the illumination lamp (121) being arranged at one side, facing towards an inner wall (111) of a side plate, of the side surface of the shading plate (122); the guide rail unit (13) comprises a guide rail (131) arranged along one side, on which the illumination unit (12) is not arranged, of the side surface of the shading plate (122), and an adjustable support frame (132) arranged on the guide rail (131) and used for erecting a photographing apparatus, and the guide rail unit (13) further comprises a stepping electric motor arranged on the adjustable support frame (132); and the control unit (14) is in communication connection with the illumination unit (12) and the guide rail unit (13), and the control unit (14) is used for adjusting the light-emitting brightness of the illumination lamp (121) in the illumination unit (12) and controlling reverse rotation of the stepping electric motor, so as to control the adjustable support frame (132) to move on the guide rail (131). According to the invention, the light received by a photographed object is more uniform, thereby improving the imaging effect of the photographed object.
