摘要： A fine-displacement adjusting device is constructed to have a first base portion and a second base portion spacedly encircled therewithin. The fine-displacement adjusting device further includes a first retractable element biased between the first and second base portions, and a first resilient element biased between the first and second base portions. The first retractable element is configured to extend and retract its length along a first axis to move the second base portion in a reciprocating manner. When the second base portion is moved by the first retractable element, the first resilient element moves the second base portion along the first axis to restore the second base portion. Therefore, the second base portion is fine-moved along the first axis in a reciprocating manner for adjusting the fine-displacement of an optical lens relative to an optical light source of a light engine in the first axis.

摘要： An optical deflector capable of making a swing angle of a reflective plate larger is provided. In drive elements, since a size in the Y direction at first positions separated by a first distance from the reflective plate is larger than a size in the Y direction at second positions separated by a second distance from the reflective plate, the second distance being greater than the first distance, it is possible to increase displacement of tips of beam portions at the first positions and to make a swing angle of the reflective plate large by increasing a generated force of the entire beam portions.

摘要： A stored energy release comprises an actuatable member slidably received within a housing. The actuatable member has an extended orientation wherein a portion of the actuatable member extends outwardly from the housing and a retracted orientation wherein the actuatable member resides within the housing. A biasing member is located between the actuatable member and the housing biases the actuatable member to the retracted orientation. A shaft is within the housing with the actuatable member configured for sliding movement along the shaft. A retaining member is located between the actuatable member and the shaft. The retaining member maintains the actuatable member in the extended orientation whereby potential energy is stored within the biasing member. A piezoelectric element selectively engages the retaining member to disable the retaining member and release the stored potential energy within the biasing member to place the actuatable member in the retracted orientation.

摘要： The present invention relates to a piezoelectric motor that can be moved with very fine resolution at the nanometer level by means of a piezoelectric element (piezo actuator) that increases in length when a voltage is applied. The piezoelectric motor according to the invention is characterized by comprising a body having an upper surface and a lower surface, and a side connecting the upper surface and the lower surface, a piezoelectric material disposed on the upper surface of the body and extending longitudinally therefrom, and a rod having an upper surface and a lower surface, and extending longitudinally, and having one end connected to one end of the piezoelectric body and disposed on the upper surface of the body, and a support member disposed to span the rod and providing a predetermined frictional force on the rod, wherein the support member is driven by the rod to interlock with a contraction or an expansion of the piezoelectric material, wherein a lower surface of the support member and the upper surface of the body are at least partially in butted, and wherein the support member is driven by sliding on the upper surface of the body.

摘要： A lens driving mechanism includes first and second piezoelectric rods that move a lens and first and second sensors that detect a position of the lens. An angle formed between a line (a first piezoelectric line) that extends from the first piezoelectric rod to be perpendicular to an optical axis and a line (a first sensor line) that extends from the first sensor to be perpendicular to the optical axis is smaller than 90°. An angle formed between a line (a second piezoelectric line) that extends from the second piezoelectric rod to be perpendicular to the optical axis and a line (a second sensor line) that extends from the second sensor to be perpendicular to the optical axis is smaller than 90°.

摘要： Disclosed is an interaction system between a controller and a VR application. The interaction system includes a controller including a first actuator configured to move a mass and a first processor configured to control an operation of the first actuator; and a content execution device configured to execute an application according to a control signal received from the controller and generate a feedback signal to transmit the generated feedback signal to a controller when a virtual object change event occurs during the application execution, wherein the first processor of the controller controls the first actuator when the feedback signal is received to move the mass and move a center of gravity. According to the present disclosure, since the center of gravity and the length of the controller operated by the user in reality may be changed in linkage with a change of the virtual object displayed on the display while executing the VR application, it is possible to greatly improve the immersion and feeling of use of the user.
