A mud flap system for a tractor is described. The mud flap system includes brackets that clamp or secure to a frame of the tractor. Lateral extensions engage to the brackets to support covers over a top surface of rear wheels of the tractor.

A method of retrofitting a window covering with a motorized tilting assembly. The method includes removing a tilt rod from a blinds tilting mechanism and introducing the motorized tilting assembly into the blinds tilting mechanism. The assembly includes a motor, a gearbox having an internal enclosure and an external enclosure, and an output shaft. The internal enclosure encloses gears, and the external enclosure encloses the internal enclosure. The output shaft includes a through-channel and extends through the internal enclosure and the external enclosure. The method further includes: selecting a tilt rod adapter having an internal shape complementary to the tilt rod and an external shape complementary to the through-channel of the output shaft; inserting the tilt rod adapter into the output shaft; and reinstalling the tilt rod such that the tilt rod passes completely through the output shaft and the tilt rod adapter.

A self-locking handrail system includes a female profile and a male profile. The female profile includes a first leg, a first locking extension that is approximately parallel to the first leg, having a gap formed therebetween, and a first vertical leg extending from the first locking extension approximately orthogonal to the first locking extension. The male profile includes a second vertical leg, and a second locking extension extending from a free end of the second locking extension, forming a fulcrum. A panel is positioned between the first vertical leg and the second vertical leg. A bar is positioned between the panel and the second vertical leg, the bar having first and second surfaces opposite one another that are not parallel with one another, causing the female and male profiles to engage by tilting the second vertical leg outward from the panel and about the fulcrum.

A light-emitting display system has an alignment mechanism to align or angle light-emitting tiles of the display. A first tile connects to a second tile by joining a first clamp portion on the first tile with a second clamp portion on the second tile. In an implementation, the alignment mechanism includes a replaceable angle adjustment insert that is inserted into at least one of the clamp portions, such as the first clamp portion. When the first and second clamp portions are joined, a surface of the second clamp portion presses against the insert and a desired angle between the first and second tile is formed. The insert can have any angle so that any desired angle can be formed between the first and second tiles.

A mud flap system for a tractor is described. The mud flap system includes brackets that clamp or secure to a frame of the tractor. Lateral extensions engage to the brackets to support covers over a top surface of rear wheels of the tractor.

A method in accordance with the invention includes a headrail bracket configured to be inserted into a headrail at an angle from a top thereof. The headrail bracket includes clips snap into a top edge of the headrail, and an attachment mechanism to attach to a gearbox assembly configured to rotate a tilt rod of a window blind tilting mechanism. In certain embodiments, the headrail bracket is a single component with a substantially low profile. This headrail bracket may span a top of the headrail. In other embodiments, the headrail bracket includes a first component to secure a first end of the gearbox assembly to the headrail and a second component to secure a second end of the gearbox assembly to the headrail. In certain embodiments, the first component slides over the first end of the gearbox assembly and the second component slides over the second end of the gearbox assembly.

System and method for mounting one or more photovoltaic modules includes one or more flexible rods, including a first end and a second end opposite the first end, each of the one or more flexible rods further including an inner core and a first jacket surrounding the inner core between the first end and the second end. The first end is configured to be attached to at least one photovoltaic module using one or more first adhesive materials. The second end is configured to be inserted into at least one hole of a modular rail and attached to at least the modular rail using one or more second adhesive materials. The one or more flexible rods are configured to allow at least a lateral movement in a first direction between the photovoltaic module and the modular rail and support at least the photovoltaic module in a second direction.

Disclosed are alternate embodiments of various components of a barrier operator system. and methods of operation, including of the mechanical drive subsystem with segmented and self-locking rail unit, rail mounting supports, belt and chain drive tensioning, and drive assembly carriage and interface; the electronics and software routines for controlled operation of the various barrier operator functions; wall console communications with the barrier operator; encryption and decryption of access codes; establishment and monitoring of travel limits and barrier speed and force profiles; thermal protection of barrier operator drive motors; and establishment and control of communications from the barrier operator to accessories by way of a wireless adapter.

A mud flap system for a tractor is described. The mud flap system includes brackets that clamp or secure to a frame of the tractor. Lateral extensions engage to the brackets to support covers over a top surface of rear wheels of the tractor.

Retractor systems and methods for retracting body tissue during surgery. The retractor system includes a rail having two opposed widened rail portions separated by a narrowed portion, each widened portion engageable by a separate clamp. The clamps are configured to support the rail to a fixed surface, or to support a surgical device. Each clamp may independently be positioned or slid along the rail to a desired location without interference with a clamp on an opposing widened rail portion. A device clamp is formed of spherical mating portions which enable alignment of a surgical device along six degrees of freedom, and tightenable by securing a single fastener. A retractor blade mount enables an angular and tilting disposition of a retractor blade, as well as remote manipulation of the retractor blade.
