A lighting assembly for a recessed luminaire includes a plaster frame for supporting the recessed luminaire and a pair of telescoping bars for attaching the plaster frame to framing support members. The telescoping bars include a first bar and a second bar, each of the bars having a generally S-shaped cross-sectional profile that is defined by a center curve joining a first area and a second area, which are generally hook-shaped and extend perpendicularly from the center curve in opposing directions. The first area of the first bar is overlappingly positioned at least in part within the second area of the second bar, and the first area of the second bar is overlappingly positioned at least in part within the second area of the second bar whereby the first and second bars are mated in an inverted and opposed adjacent relationship allowing sliding extension of the bars.

The present invention relates to portable hose carts for handling and storage of flexible hoses, such as garden or air hoses. The cart is primarily constructed of plastic components having a centrally rotatable spool for winding of the flexible hose, an enclosure for supporting the spool, wheels at one end of the base of the enclosure, and a handle assembly for tilting the frame onto the wheels to facilitate moving the device. The handle assembly is telescoping mounted and includes a handle mounted near the top of the handle assembly. The spool is rotatable by either a direct current powered motor or a folding manual crank. Power from the electrical motor is transferred to the spool via an infinitely adjustable torque transfer assembly. When the cover is in the open position, the direct current motor is operationally locked out, and when the cover is rotated into the closed position, the direct current motor is operable. The device may further include a reciprocating guide assembly that operates during rotation of the spool to rewind the hose into a compact configuration.

A low orbit optical imaging satellite has a long thin satellite body housing an optical telescope arrangement. A major part of the telescope arrangement has its optical axis roughly parallel to the direction of elongation and includes a mirror arrangement deployed to direct a line of sight of the optical telescope out sideways from the direction of elongation. The transverse dimensions of the satellite body are preferably minimized to be close to the optical aperture dimension of the optical telescope, thereby providing a high ballistic coefficient and high orbit lifetime for orbits in the low thermosphere.

The invention discloses a synthetic aperture type high-resolution imaging telescope device based on a bright source. The synthetic aperture type high-resolution imaging telescope device is composed of a receiving pupil whose diameter d is matched with the current observatory address seeing, a synthetic aperture type optical imaging system and a telescope imaging system having a main mirror diameter of D. A sparse aperture array and delay line compensators are arranged in the synthetic aperture type optical imaging system. The sparse aperture array includes a plurality of sub-mirrors having an aperture of d which are distributed in a plurality of multistage two-dimensional spaces. The sub-mirrors comprise a spectroscope, a transmitting mirror and a plane mirror. The delay line compensators are arranged on the output optical path of each sub-mirror separately. The plurality of sub-mirrors are used to acquire nearly-complete real-time UV plane coverage on a focal plane through the multistage spectral arrangement according to the energy ratio. The delay line compensators are used to compensate the optical path difference of each aperture to acquire the outgoing diffraction limit wavefront on the sparse aperture array longest baseline D and output the outgoing diffraction limit wavefront to the telescope imaging system having a main mirror diameter of D. According to the invention, advantages of low cost and simple system can be realized, and high time and space resolution diffraction limit imaging can be obtained on a real-time basis.

A manual controller commands a telescope mount to automatically track a specific bright star after the image of the star is located to center of an electronic eyepiece and a timer is started. The average moving speed of the bright star is calculated after a predetermined elapsed time to acquire the right ascension (RA) and the declination (DEC) coordinates of this bright star. Subsequently, the RA and DEC coordinates are compared with pre-stored data contained within a database used to identify the bright star. The celestial sphere coordinates of the telescope can be determined after a minimum of one bright star is identified. In the auto-tracking procedure, the manual controller controls movement of telescope by feedbacks of the drifting speed and direction of the specific bright star in an electronic eyepiece for the purpose of keeping the specific bright star in the center of the electronic eyepiece.

A system with a calibrated rotary encoder can be used for accurate telescope tracking along the Right Ascension (RA) rotation axis. The system includes an incremental quadrature optical encoder, a microcontroller unit (MCU), a timer, an electronic memory, and a control interface. The rotor of the encoder is coaxially attached to the RA drive shaft of the telescope mount in order to send angular position data for the RA drive shaft to the MCU. The MCU evaluates the angular position data for errors and send corrections to the control mechanism of the RA drive shaft. The electronic memory stores calibrated reference data, which is compared to the angular position data by the MCU. The calibrated reference data can be found by measuring the movement of a reference star across an image. The system can also calculate an accurate visible speed for the Earth's rotation in a desired direction.

A disc-based altitude-azimuth telescope mount for mounting and adjusting a telescope along altitude and azimuth axes. The telescope mount includes an azimuth disc assembly for facilitating adjustment of the telescope along the azimuth axis and an altitude disc assembly for facilitating adjustment of the telescope along the altitude axis. A friction adjusting mechanism operably engages the azimuth disc assembly and the altitude disc assembly to prevent inadvertent movement of the telescope along both axes. A digital setting circle may be operably connected to the disc assemblies to facilitate automatic adjustment of the telescope, as desired.
