Patent CA-2144564-A1 (CA)
Title: Hydraulic floating system for downpressure control of seeding tools
Inventor: JANELLE LUC
IPC: A01C7/20
Filed: 1995-03-14
Abstract: A hydraulic downpressure system for use on no-tillage seeders allows for a constant downward force to be applied on seeding tools operating in highly variable soil surface conditions in order to keep a uniform seeding or planting depth. Raising and lowering of the seeding units can also be achieved with this hydraulic system. A double acting hydraulic cylinder is principally used having its rod end connected to one or two seeding units. A hydraulically operated two-way mode selection valve provides system shifting between both modes involved.        The first mode- is used when transporting the seeder on roads and to operate the seeding tools in the field. Control is then provided by a three-way directional valve mounted to an external hydraulic power supply, such as an agricultural tractor.      Raising and lowering of the seeding tools can be achieved when operating in this mode. A second mode is involved when the seeding tools are working into the ground to sow seeds. Pressure applied on both ports of the hydraulic cylinder comes from a nitrogen accumulator that acts as a pressure absorber which results in a net downward force. The cylinder can thus move independently while always maintaining the same force. A second three-way directional valve regulates the pressure in the accumulator and protects system from overload pressure. Downpressure adjustment is directly dependent from this control valve. A pressure compensator prevents a differential of pressure during system mode changes. The force from one cylinder can be applied on two seeding units using a double linkage system.

Title: Computationally efficient adaptive bit allocation for encoding method and apparatus with allowance for decoder spectral distortions
Inventor: FIELDER LOUIS DUNN
IPC: G10L19/035
Filed: 1994-07-15
Abstract: The invention relates in general to low bit rate encoding and decoding of information such as audio information. More particularly, the invention relates to computationally efficient adaptive bit allocation and quantization of encoded information useful in high-quality low bit-rate coding systems. In audio applications, a digital split-band encoder splits an input signal into frequency subband signals having bandwidths commensurate with the critical bandwidths of the human auditory system, quantizes the subband signals according to values established by an allocation function, and assembles the quantized subband signals into an encoded signal. The allocation function establishes allocation values in accordance with psychoacoustic principles with allowance for decoding synthesis filter bank spectral distortions. In one embodiment, an allocation function establishes allocation values using a psychoacoustic masking threshold generated by estimating the power spectral density (PSD) of the input signal, generating an excitation pattern by applying a basilar-membrane spreading function to the PSD, adjusting the excitation pattern by an amount equal to a sensitivity function which specifies a signal-to-noise ratio (SNR) sufficient to achieve psychoacoustic masking, comparing the level of the adjusted pattern to the threshold of hearing and generating the psychoacoustic masking threshold which is equal to the larger of the two. An allocation function may allow for decoder synthesis filter bank spectral distortions in any of a number of ways such as by adapting the sensitivity function.

Ce second système met en oeuvre un groupe de détecteurs de température placés à proximité immédiate de chaque électrode venant en contact avec le tissu, et met également en oeuvre un algorithme approprié sensible à la dérivée. Les deux systèmes sont exploités dans un mode multiplex par l'intermédiaire d'un premier multiplexeur. Un second multiplexeur applique la puissance de sortie en alternance aux diverses électrodes, indépendamment et séparément.

Title: Selective droplet dispersion technique
Inventor: PIATT MICHAEL J
IPC: G06K15/10
Filed: 1996-05-03
Abstract: The present invention provides for selective droplet dispersion. The selective droplet dispersion technique of the present invention is used to optimize image quality from a continuous ink jet printer.  Initially, a pixel to be printed is identified, and then placement of droplets within the pixel to be printed is selected to optimize image quality. The selection can be unconditional, wherein the placement of droplets is not dependent on neighboring pixels. Such selection includes printing first or last available droplets, or centering the droplets within the pixel to be printed. The selection can also be conditional, wherein placement of droplets is dependent on surrounding pixels. Such selection includes providing data from at least one surrounding pixel relative to the identified pixel and using the surrounding pixel data to select droplet placement within the identified pixel.

Title: Spring Trip Shank Assembly Having Quick-Dropping Trip-Out Force and Improved Resetting Ability
Inventor: DOBSON DAVID A
IPC: A01B61/04
Filed: 1997-03-06
Abstract: The spring trip assembly has lever mechanism between the shank and the compression spring which causes the trip-out force of the shank to drop sharply once the relatively high, initial trip-out force level has been reached, thus permitting the shank to slide up and over obstructions without breakage. The compression spring is actuated from both ends simultaneously as the shank rises so that although the trip force drops off quickly, energy also builds up quickly in the spring. Thus, the trip force does not drop as low as it otherwise would, assuring that ample return force is available to reset the shank down into the soil in its working position. Various components of the assembly can be removed and replaced easily without disassembling the entire unit from the tool bar.
