The goggles of the invention utilize a substantially rigid frame with separate top and bottom individually rotatable elements, namely an upper browbar and a lower nosepiece, that firmly capture the lens from above and below. The lens is further secured to the frame by projections on each of the browbar and nosepiece which fit through apertures in the lens. At the top, a post which projects forwardly from the frame is received in the well of the browbar by snap-fit engagement. At the bottom, a prong on the rotatable nosepiece passes through a bottom aperture of the lens and is received in a recess of a bottom portion of the frame by snap-fit engagement. The apertures and cooperating projections are preferably located along the center of a one-piece lens. Thus, the rotatable browbar and nosepiece capture the lens top and bottom by edgewise compression and hold the lens front-to-back.

There is disclosed a sound attenuation panel comprising, a rigid frame divided into a plurality of individual cells, a sheet of a flexible material, and a plurality of weights. Each weight is fixed to the sheet of flexible material such that each cell is provided with a respective weight and the frequency of the sound attenuated can be controlled by suitable selecting the mass of the weight.

An exercising apparatus for allowing mobility recovery and slimming activities. The apparatus is an endless belt-like exercising sport mat device which comprises a) an endless belt padded with a relatively soft and elastic material for serving as a sliding sport mat; b) a rolling mechanism for allowing the endless belt to be looped at a relatively low speed around the rolling mechanism, thereby providing a lower belt section and an overlying upper belt section on which a user may perform such activities; c) a supporting surface disposed under the inner surface of said upper belt section supporting relation thereto and depressible therewith under the weight of a user for aiding the user to move the endless belt; and d) a rigid frame for containing the supporting surface and the rolling mechanism.

A retractable step for use with a vehicle comprises a stepping member having a stepping deck, a first arm, a second arm, a motor and a stop. The first arm has a first end pivotally attached to the vehicle, and a second end pivotally attached to the stepping member. The second arm also has a first end pivotally attached to the vehicle, and a second end pivotally attached to the stepping member. The motor is drivingly connected to the first arm such that a rotation of the motor causes rotation of the first arm about its first end and moves the stepping member from a retracted position to an extended position, or vice versa. The stop is located within the range of motion of the second arm such that the second arm bears against the stop when the stepping member is in the extended position. The first and second arms are situated such that the first arm is loaded in compression and the second arm is loaded in tension when the stepping member is in the extended position and a load is placed upon it. In another embodiment, a retractable vehicle step assist comprises a rigid frame, a forward planar linkage pivotably connected to the frame along a forward upper connection width, and a rearward planar linkage pivotably connected to the frame along a rearward upper connection width. The retractable vehicle step further comprises a rigid step member having a stepping deck. The step member is pivotably connected to the forward planar linkage along a forward lower connection width, and is pivotably connected to the rearward planar linkage along a rearward lower connection width and on a side of the forward planar linkage opposite the stepping deck. The stepping deck is substantially wider than any of the forward upper connection width, the rearward upper connection width, the forward lower connection width, and the rearward lower connection width.

An accessory device mounting platform includes a substantially rigid frame and a substantially rigid mating tray that are slidably interconnected along a first direction, the frame and tray include a tongue-and-groove slide mechanism arranged therebetween for sliding the tray relative to the frame relative to a first direction. A resilient biasing mechanism, such as a cantilevered flexure or tension spring, is coupled between the frame and a latch bolt portion of a clasp mechanism for biasing the latch bolt portion toward a latch strike plate mechanism formed in the tray. The latch strike plate mechanism is formed with an inclined surface that is positioned to engage a latch bolt portion of the clasp mechanism and is structured for deflecting the latch bolt away from the frame, while the resilient biasing mechanism of the clasp mechanism is structured for biasing the latch bolt back toward the frame.

This invention relates to a briefcase or carrying case for a mobile office, holding a number of interconnected electronic devices (laptop computer, printer, and the like) which may be opened up for immediate use of the devices. A rectangular rigid frame comprises the foundation and ancillary items are fastened to the frame. An enclosing cover having a zipper is also attached to the frame. Shock-absorbing foam and straps are included. An optional wheeled caddie can support the frame using coupling blocks on each side of the frame.When in use, the laptop extends forward from the frame in a low flat position. The printer, held on a second hinged tray, is flipped backwards by 270 degrees over the top of the frame, so that the weight of the printer and the weight of the laptop tend to counterbalance each other and the carrying case is stable.

Collaborative coexistence of co-located mobile WiMAX, wireless LAN, and / or Bluetooth radios. Within a communication device that includes multi-protocol communication capability, the various radio modules included within such a communication device operate cooperatively such that collisions are avoided between those various radios. When a first of the radio modules operates as governed by a relatively rigid frame structure, a second of the radio modules capitalizes upon that predetermined nature (of the relatively rigid frame structure) to support communication during times in which that first radio module has a lower level of activity (e.g., turned off completely, within a power savings mode, in a sleep mode, etc.). The radio module operation is performed within a time-orthogonal manner, such that multiple radio modules are not attempting to transmit or receive simultaneously. Moreover, CTS2SELF operation can be employed alone or in conjunction with power savings operation of co-located radios within a communication device.
