  • Publication number: 20250069509
    Abstract: Various embodiments of a system and method for a smart work zone are described. In one example, the system includes smart cone devices configured to transmit smart cone device localization data, a wearable device comprising a processor configured to transmit worker localization data of a worker wearing the garment device and to receive an alert, and a base station. The base station includes an internal edge computing system configured to process the smart cone device localization data to define a virtual geofence boundary of a safe area, process the worker localization data, broadcast a location of the worker wearing the wearable device, and in response to a vehicle or the worker approaching the virtual geofence boundary, provide an alert to at least one of: the worker wearing the wearable device, a passing motorist, or a connected and automated vehicle (CAV).

  • Patent number: 11852803
    Abstract: A method includes rotating a mirror assembly in a first direction using an actuator. The mirror assembly is rotationally coupled to a base and includes a mirror. A first end of the mirror is rotationally coupled to the base, and a second end of the mirror is not supported by or attached to another structure. The method also includes rotating a reaction inertia assembly in a second direction opposite the first direction using the actuator. The reaction inertia assembly is rotationally coupled to the base. The method further include restricting movement of the mirror assembly and the reaction inertia assembly in multiple degrees of freedom using multiple flexures.

  • Patent number: 11566662
    Abstract: A flexure device comprising an interior flexure member having first and second interior flexible blades each formed with an interior end portion and separate interior body portions. An exterior flexure member can have first and second exterior flexible blades each formed with separate exterior end portions and an exterior body portion. The first interior end portion and the first exterior end portion form a first flexure end portion, the second interior portion and the second exterior portion form a second flexure end portion. The interior and exterior body portions are coupled to form a flexure body portion, such that the first interior and exterior flexible blades form a first flexure that facilitates rotation between the first flexure end portion and the flexure body portion. The second interior and exterior flexible blades form a second flexure that facilitates rotation between the second flexure end portion and the flexure body portion.

  • Patent number: 10771710
    Abstract: A shutter assembly comprises a base coupled to a photosensor assembly, a flexure device supported by the base, and a shutter arm rotatably coupled to the base via the flexure device. An actuation mechanism is coupled to the shutter arm via the flexure device, and is operable, upon application of an electric field, to rotate the shutter arm from a first position to a second position (or to a third position) to manage light relative to a photosensitive device of the photosensor assembly. Upon rotation of the shutter arm to the second position, the flexure device stores energy such that, upon removal of the electric field, the flexure device releases the stored energy to return the shutter arm to the first position. A keeper magnet can be provided to maintain the shutter arm in the second (actuated) position, so that the electric field can be removed while the keeper magnet maintains a magnetic force to keep the shutter arm in the second position.

  • Patent number: 9784759
    Abstract: A thermally insensitive open-loop hung mass accelerometer utilizes a transverse geometry to attach the body/flexures/proof mass so that thermal expansion effects due to thermal gradients across the accelerometer or bulk temperatures changes of one flexure relative to the other cause minimal or no axial displacement of the proof mass. In this geometry, multiple flexures may be stacked to achieve the required stiffness, thus reducing manufacturing costs and any tolerancing issues, without affecting thermal sensitivity. The accelerometer is suitably designed to exhibit a radial symmetry. The accelerometer is suitably designed to use low CTE materials for at least the proof mass and body and a low thermal expansion differential Eddy current sensor head.

  • Publication number: 20140158688
    Abstract: A closure for a container is described. The container has an opening through which contents of the container are dispensed and a holding member (255, 285, 295, 305, 315, 316, 317, 340, 350) for cooperating with the closure to retain the closure on the container. A sealing member (220) is configured to sealingly close the container opening. The sealing member includes a retention member (260, 275, 290, 300, 310, 325, 335, 345, 355) engageable with the holding member of the container to retain the sealing member in sealing engagement with the container. A cap member (225) has a top rim and a sidewall depending from the top rim. The sidewall includes an attachment member (160) for attachment to the container and an engagement member (245) that operatively couples the sealing member to the cap member upon placement of the cap member on the container. The cap member is rotatable relative to the container and relative to the sealing member.
