There is a need for a small and fast optical zoom device that can change magnification. Conventional zoom devices require coupled mechanical motions to adjust the axial separations between individual or groups of elements in order to change the optical magnification. The mechanical motions decrease the speed of zooming, increase space and weight for zoom system, may induce unwanted jitter, and require large power consumption. In addition, the mechanical zoom system is restricted to magnifying the area on-axis. To solve problems of conventional zoom system, the zoom system utilizing one or more variable focal length micromirror array lenses without macroscopic mechanical motion of lenses is invented.

A three-dimensional display device includes a two-dimensional display displaying a first image, and a variable focusing lens receiving light from the two-dimensional display and forming a second image. The variable focusing lens reflects light from the two-dimensional display. The first image includes a predetermined number of first depthwise images that are displayed within a unit time, and the second image includes corresponding second depthwise images. Each depthwise image represents the portion of the first image having the same image depth, and the two-dimensional display displays one depthwise image at a time. The focal length of the variable focusing lens changes according to the depth of the depthwise image being displayed. A micromirror array lens is used as the variable focusing lens. The micromirror array lens has enough speed and focusing depth range for realistic three-dimensional display.

A method for reducing or preventing the occurrence of chronic tension headaches, migraine headaches, or temporormandibular disorders, including the application of a therapeutic, non-disabling, non-disfiguring dose of Botulinum Toxin Type A to the temporalis and/or messeter muscles of a patient, in combination with the use of a semi-custom intraoral discluder device that can be placed on either the upper teeth or the lower teeth to prevent contact of opposing upper and lower teeth. The combination of the use of an semi-custom intraoral discluder device with the administration of Botulinum Toxin Type A to the temporalis and/or messeter muscles, provides a greater reduction in maximum clenching than the use of Botulinum Toxin Type A or the semi-custom discluder device alone.

A vibration isolating system is disclosed. The vibration isolating system comprises a passive mechanical system comprising a damping assembly, a first resilient member coupled in series with the damping assembly, and a second resilient member coupled in parallel with the series combination of the damping assembly and the first resilient member. The vibration isolating system further comprises a support member coupled in series with the passive mechanical system, a viscoelastic mount coupled to the support member, and a motion limiter coupled to the support member such that the passive mechanical system transmits a force to the support member when the passive mechanical undergoes longitudinal displacement greater than a predetermined displacement.

A die assembly adapted to be attached to one of a wrench first arm and a wrench second arm. The die assembly includes a die having a pipe facing front spaced apart from but parallel to the pipe longitudinal axis, a wrench facing rear, and two spaced apart opposed sides, each connected to the die front and die rear. The die is thick on one side and thin on the other side so that the die facing front has a face that recedes from the pipe from one edge to the other edge so that contact between the die facing front varies depending upon the diameter of the pipe. The die rear also has a convex curve so that the die has a thick mid section.

A device for allowing the puborectalis muscle to relax for easier fecal matter evacuation. The device differs from current units because it is a lightweight, portable unit that can collapse and be hidden away from view. The device has a nonslip foot rest that is adjustable based on differences in height of users. An unlocking mechanism enables a user to unlock the foot rests and fold them for easy storage.

Fluid amplifiers and vibration damping and isolation systems are provided. A fluid amplifier includes a housing assembly, a piezo-electric element, two amplification stages, and a rod. The piezo-electric element is disposed within the housing assembly and is capable of being energized to lengthen axially to provide an input stroke at an initial magnitude. The first amplification stage is disposed within the housing assembly adjacent to the piezo-electric element and is adapted to amplify the input stroke from the piezo-electric element to a first magnitude. The second amplification stage is disposed in series with the first amplification stage and is adapted to increase the input stroke from the first magnitude to a second magnitude that is greater than the first magnitude to yield an amplified input stroke. The rod extends through the second amplification stage and is coupled thereto to transmit the amplified input stroke having the second magnitude.
