  • Patent number: 10082572
    Abstract: An apparatus includes an extendable wand, and a sensor head coupled to the wand. The sensor head includes a continuous wave metal detector (CWMD) and a radar. When the wand is collapsed, the wand and the sensor head collapse to fill a volume that is smaller than a volume filled by the sensor head and the wand when the wand is extended. Frequency-domain data from a sensor configured to sense a region is accessed, the frequency-domain data is transformed to generate a time-domain representation of the region, a first model is determined based on the accessed frequency-domain data, a second model is determined based on the generated time-domain representation, the second model being associated with a particular region within the sensed region, and a background model that represents a background of the region is determined based on the first model and the second model.

    Abstract: An actuator for a flap on an item of furniture includes at least one actuating arm that is mounted to pivot between a closed position and an open position in order to move the flap, a spring device for acting on the actuating arm, and a transmission mechanism for transmitting the force of the spring device onto the actuating arm. An adjustment device allows the transmission mechanism to be shifted between at least two operating positions. In a first operating position, the spring device applies a closing force, in the direction of the closed position, onto the actuating arm which is in an opening position immediately upstream of said closed position. In a second operating position, when said actuating arm is in the aforementioned, immediately-upstream opening position, the spring device exerts a force which acts in the direction of the open position.

    Abstract: An asymmetrical resistant hinge set includes at least a resistant hinge and an elastic element coaxially positioned. The resistant hinge is hinged on a first pivotal means located on the bottom side of a body. The elastic element provides action forces on the resistant hinge and one-way resistance to generate an asymmetrical hinge effect with a greater resistance in one direction and a smaller resistance in another direction when a support lid is flipped in forward and reverse directions to reduce the resistance of the resistant hinge. As a result, when the support lid is flipped to a selected angle it still can bear the weight of the body of a portable electronic device at the anchored position without drifting.

The drive mechanism has a driving mechanism such that a movement from the first position to the second position can be initiated initially by a slight movement and the additional movement is then effected automatically through spring force (F) until the second position has been reached. The movement out of the first position into the second position is possible in either a clockwise and counterclockwise movement. The driving mechanism comprises a driven part, one operating part and two drives that are in the form of a force storing device The force storing devices interact with the driven part in opposing directions in such a manner that only the one for storing device is in driving connection with the driven part while the other force storing device is retained in its starting position.

The extendible hinge allows the door to pivot through a range of pivotal positions and, when necessary, allows the door to move through a range of extended positions. The pivotal positions allow the door to open and close normally across a doorway, while the extended positions help protect the door assembly from damage in the event the door is forced to swing beyond its pivotal positions. In some embodiments, the door includes a spring-tensioned chain that draws the inner edge of the door against an anchor attached to a side edge of the doorway. The flexibility of the chain allows the door to pivot, while the compliance of the chain's spring allows the door to shift away from its normal pivot point and move to various extended positions.

  • Patent number: 6526627
    Abstract: An hinge auto-return device for a glass door includes a body containing a longitudinal pivot hole to rotatably receive a pivot pin in the body and a lateral guide hole to movably receive a positioning block in the body. The lateral guide hole extends perpendicular to communicate with the pivot hole. At lest one blind hole is longitudinally defined in the positioning block to mount at least one resilient member in the positioning block. The positioning block has a contact face forced by the resilience of the resilient member to press against a flat segment of the pivot pin when a hinge assembled with the auto-return device is attached to a glass door and hinges the glass door on a doorframe. The positioning block is able to slide smoothly in the guide hole in the body of the auto-return device so that the auto-return device performs reliably and durably.

  • Patent number: 6510588
    Abstract: A turning mechanism for providing a turning motion, and a hinged electronic device. The turning mechanism comprises a power element which is arranged to generate the turning force for the turning motion, and a damping element which is arranged to control the speed of the turning motion. The damping element comprises a substantially cylindrical casing inside of which a spindle is mounted using a clearance fit. The power element is connected with respect to the spindle to allow the spindle to rotate inside the casing along with the turning motion. The clearance fit between the casing and the spindle is provided with an elastic medium which controls the motion of the spindle with respect to the casing and dampens the stopping of the turning motion.

    Abstract: A hinge mechanism for joining a door to a vessel is disclosed. The hinge mechanism includes a housing having a first end and a second end, and a rod reciprocally disposed in the housing, with the rod having a first end adapted to pivotally engage the door and further having a second end. A spring is disposed within the housing. A first coupling slidably connects a first end of the spring to the first end of the rod, and a second coupling slidably connects a second end of the spring to the second end of the rod. The spring, the housing, and the first and second couplings cooperate to permit movement of the rod between an outward position, an inward position, and a neutral position between the outward position and the inward position. The spring is arranged to bias the rod toward the neutral position.

  • Patent number: 5600868
    Abstract: A hinge (20) includes two hinge plates (22, 24) and a connecting hinge pin (32). A coil spring (48) supported on a bushing (44) overlies the hinge pin (32), which is free to move along its longitudinal axis (30). A cam follower (42) on the hinge pin (32) engages a cam (32) mounted to one of the hinge plates (22), so that the hinge pin (32) slides longitudinally as the hinge plates (22, 24) pivot relative to each other about the hinge pin (32). As the hinge pin (32) slides longitudinally, it axially compresses or decompresses the spring (48). The cam (32) is oriented such that pivoting of the hinge plates (22, 24) in either direction from an open position compresses the spring (48), providing a restoring force which tends to retain the hinge plates (22, 24) in the open position.

  • Patent number: 4616799
    Abstract: A yieldable highway swing sign is described which swings out of the way when struck by farm equipment or other objects such as wet snow from snow plows. The sign has a torsion bar which returns the sign to its original position after being struck. The sign has notches in its hinges to maintain its original position. The notches resist any displacement forces by providing an inclined plane of 40.degree. which must be overcome before the sign is displaced in an arc pivoting around the torsion bar. The displacement of the sign is limited to a 90.degree. displacement from the original position by the configuration of the hinges and is helped by the increased torque created by the torsion bar as the sign swings further from its original position.
