Provided is a self-retracting device including a rotatable hub assembly. The rotatable hub assembly includes a first half and a second half. The first half includes a slot for an axle. The second half includes a retraction member and a slot for the axle. The self-retracting device also includes an axle with a body extending through the slot of the first half and the slot of the second half and a line. A first end of the line includes a loop, wherein the loop is between the first half and the second half and the axle body extends through an opening defined by the loop. The rotatable hub assembly is configured to retract the line when the rotatable hub assembly moves in the first rotational direction and pay out the line when the rotatable hub assembly moves in a second rotational direction opposite the first rotational direction.

The present disclosure relates to a holding apparatus for holding a card. The holding apparatus comprises at least two proximity sensors, a control unit and a motor. Each of the at least two proximity sensors are configured to determine orientation of the card when the card is present in the holding apparatus. The control unit is configured to determine status of each of the at least two proximity sensors in order to determine a position of the holding apparatus. The status of the at least two proximity sensors is at least one of open and close. The control unit is further configured to transmit a control signal to the motor based on the determined status. The motor rotates the card upon receiving the control signal, thereby orienting the card with respect to a viewer of the card.

A cable handling assembly is adapted to store and pay-out a telecommunications cable. The assembly includes first and second sets of pulleys, a housing, and a cable route. The first and second sets of pulleys are spaced from each other by a take-up distance that decreases upon the cable being paid-out. The housing supports the pulleys and also guides the pulleys as the take-up distance changes. The cable route is routed between the first and second sets of pulleys. A stack of pulley sets may be formed and may include at least one intermediate pulley set positioned between the first and second pulley sets. The cable route is routed between adjacent pulley sets of the stack of pulley sets. A route length decreases as the take-up distance decreases. A rack unit for organizing a plurality of telecommunications cables in a telecommunications rack may include a plurality of the cable handling assemblies. At least one of the cable handling assemblies may include a retraction apparatus that further adapts the at least one cable handling assembly to retract the corresponding telecommunications cable.

A remote controlled retractable leg iron device provides a restraint device which can be used by police or any other authority to maintain control of persons while in transport. The device is remote controlled so an operator can control the wearer from a distance. The cuffs are secured to the legs of the wearer and are attached to the housing unit by cables which coil around winch drums within the housing unit. The winch drums rotate freely in a normal operation mode so that the wearer can walk or move with little resistance. In an emergency mode, the device retracts the wire cables into the housing unit so that the wearer's legs are restrained tightly together—removing the lack of resistance and thus stopping the wearer's motion. The emergency mode is activated using the remote control.

Various implementations include an extended repeated-use table cover device. The device includes a roller, a non-silicone mat, a disinfecting enclosure, a table mount, and a winding mechanism. An outer surface of the roller is coupled to a first mat end such that rotation of the roller about a roller axis causes the mat to wind around the outer surface of the roller. An outer surface of the disinfecting enclosure defines an opening extending from the outer surface to a cavity defined by an inner surface of the disinfecting enclosure. The roller is disposed within the cavity, and the mat is extendable through the opening. The winding mechanism is for rotating the roller from an extended position to a retracted position. The mat is durable enough to be used for at least three months under expected standard use without needing to be replaced.

A retractable cord reel houses contacts that connect autonomously when the user aligns the spool to lock it from retracting. The spool and housing contains high quality, sensitive contacts for high speed data and other critical signals that engage when indexed by the user. The design is flexible for adaptation to a variety of applications and scalable based on cable type and length as well as the number of contacts required. The contacts are engaged when the user allows an indexing dog to engage a spool indexing housing causing the dog to shift and force a mating lever to make the electrical connection. Decoupling occurs instantly when the spool is slightly rotated by the user. The user's only action throughout the process is to pull the cable. Without this intentional action of the user, the spool, rotates freely and the contacts are not engaged.

A line retraction device includes a rotatable drum having a line associated therewith, with the line including a first end directly or indirectly attached to the drum and a second end opposite the first end, and at least one retraction member biasing the drum in a first rotational direction of the drum opposite a second rotational direction of the drum, where the drum is configured to: (i) retract the line when the drum moves in the first rotational direction; and (ii) payout the line when the drum moves in the second rotational direction. The device further including a damper assembly configured to provide rotational resistance to the drum in: (i) the first rotational direction of the drum as the line is being retracted; and (ii) the second rotational direction as the line is being paid out.

A blind body actuator used in a cordless window blind assembly is provided to include a casing, a winding mechanism, two guide units and two lift cords. The winding mechanism includes two winding wheels and a volute spring connected to the winding wheels. Each of the winding wheels is meshed with one respective lift-cord wheel so that the lift-cord wheels can be driven by the winding mechanism to rotate synchronously. The guide units are respectively disposed adjacent to one respective lift-cord wheel, each including a first cylinder roller. Each of the lift cords is wound around the first cylinder roller of one respective guide unit, having one end thereof connected to one respective lift-cord wheel and an opposite end thereof extended out of the casing.
