Title: Information source encoding apparatus
Inventor: ASANO KENICHI
IPC: H04N19/625
Filed: 1992-11-27
Abstract: An information source encoding system in which overload noise and block noise are less recognized and quantizing overload and large quantizing distortion can be reduced within an intra-frame mode encoding region even when intra-frame and inter-frame mode encoding regions coexist in an image screen. An orthogonal converter outputs conversion coefficients in a predetermined spatial frequency region.          A coefficient separating unit selectively separates the conversion coefficients.  With the separated coefficients from the coefficient separating unit, a power is calculated.          The calculated power is compared with a predetermined threshold value by a coefficient power determining unit.          A step width controller sets a quantizing step width, based on the combination of a power determining ON/OFF signal from the coefficient power determining unit and an adaptive control ON/OFF signal from the encoding controller, when the coefficient power is larger than the threshold value in the intra-frame mode, and sets a quantizing step width determined by the quantization characteristic designation signal from the encoding controller in remaining cases.  As a result, a combined adaptive quantization characteristic signal having a quantizing step width for combined adaptive control is output to the quantizer.

Title: Manually operated pickup truck hoist
Inventor: DRIVER WILFRED D
IPC: B60P1/43
Filed: 1992-12-17
Abstract: ABSTRACT OF THE DISCLOSURE:     A manual powered hoist and ramp system for pickup trucks enables a single person to lift heavy objects located on handtrucks or dollies onto the loading platform of the truck. The truck tailgate has a pivoted flap extension to form a ramp inclined from the truck loading platform to the ground when pivoted into its opened ramp position with the flap extended. An accompanying hoist has a counterforce mechanism mounted on a pair of elevated stanchion posts on opposite sides of the truck loading platform for producing an upward assisting lifting force establishing tension in a line extending to the ground for attachment to a handtruck or dolly. That force directed substantially parallel to the ramp tending to move the load up the ramp thus enables a single person to handle a heavier load, such as a refrigerator, for hoisting onto the truck platform. The hoist is manually powered and thus stores a force in the counterforce mechanism as the line is extended to ground level to attach to a loaded hand truck or the like. The counterforce mechanism relies upon the weight of lead masses or the like to provide enough lifting force that a single person can manipulate safely larger loads between ground level and the truck platform.          The hoist-ramp assembly stores on a pickup truck to convert it to a one person moving vehicle capable of moving large, heavy furniture pieces such as refrigerators.
