Inventor: FELDMAN ZEIYLIK Y
IPC: B66F9/00
Filed: 1995-09-27
Abstract: An extendable lifting apparatus for a vehicle. The apparatus includes a support bracket secured to the floor of the vehicle.  A tube is mounted to the support bracket perpendicularly to the axis of the vehicle frame.  The tube receives a boom which is used to support a cable used to lift heavy objects.  The tube is substantially rectangular and has an axial slot extending along the bottom to form an axial opening that allows the cable to be suspended therein when the boom is in the fully retracted position.  The slotted wall of the tube also acts as a floor opposite an inner ceiling. A winch is coupled to the boom for successively winding and unwinding the cable.  A motor is coupled to the tube for moving the boom from a retracted position wholly within the tube to an advanced position.  A second motor is coupled to the winch for controlling the winding and unwinding of the cable.  Control of the two motors is provided by a remote control.  Finally, a brake is provided for preventing the unwinding of the winch allowing a suspended object to freefall when the second motor experiences failure.

Abstract: The invention provides a variable bit rate discrimination method and apparatus wherein a transmission bit rate of data received by a mobile station in a mobile communication which employs a spectrum spreading method can be discriminated readily to realize reduction in time required for decoding processing and miniaturization in circuit scale.  A variable bit rate including four different transmission bit rates is used as a transmission rate of a traffic channel from a base station to a mobile station, and transmission data are encoded using convolutional encoder for error correction and transmitted.          In the mobile station, received data are decoded for the four individual transmission bit rates using Viterbi decoders, and the decoded received data are compared with coded data sequences generated from the convolution codes to obtain path metric values which are sum totals of errors of the received data.  Then, one of the transmission bit rates which exhibits a lowest one of the path metric values is selected as a bit rate used for transmission of the transmission data.          Consequently, after Viterbi decoding, no further encoding is required.

Abstract: An rms value of a sum signal series x = en + vn calculated by adding a noise series to an error signal series of a known signal series and an unknown signal series, is calculated by an rms calculator.   By means of an amplitude controller, x is output as is when ¦x¦ is smaller than a threshold value A proportional to the rms value.          When ¦x¦ is greater than the threshold value A, a product signal calculated by multiplying the polarity of x with the threshold value is output.  Utilizing the output of the amplitude controller, respective tap weights of filter is corrected to generate be tap weights Ck(n). By this, switching  control  between  a  probability  gradient  LMS algorithm ( LA ) and a probability gradient sign algorithm ( SA ) can be performed smoothly.   Thus,  an adaptively controlled filter having an advantage of small residual error and fast convergence of LA and an advantage of satisfactory strength against disturbance, such as burst noise or so forth of SA, can be obtained.

Title: Procedure for producing a reference model intended to be used for automatically checking the printing quality of an image on paper
Inventor: STRINGA LUIGI
IPC: B41F33/00
Filed: 1996-03-06
Abstract: The procedure for producing a reference model for checking the printing quality of an image composed of at least two drawings comprises the following steps:      Starting with printed test sheets, the sheets are aligned so that the drawings (a1, a2) printed in a first printing are in register. The images are recorded, storing the densitometric pixel values (a10, a11, a12, a13; a20, a21, a23) constituting the images in memory.      The minimum value obtained (a10, a12) is associated with each pixel and the model (M) for the first drawing is obtained. We continue in the same way for the second drawing.

Title: Method of compensating for changes in flow characteristics of a dispensed fluid
Inventor: BRETMERSKY CARL A
IPC: F15D1/08
Filed: 1996-04-15
Abstract: A fluid dispensing control for controlling the dispensing of a fluid by a metering valve through a nozzle onto a workpiece. An initial value of a flow characteristic of the fluid is determined that is correlated to the relationship between the flow rate of the fluid and nozzle pressure. Desired nozzle pressure values are periodically determined by evaluating a model of flow rate of the fluid through nozzle in response to the initial value of the flow characteristic and a desired flow rate value. Thereafter, the control provides command signals to the metering valve as a function of the desired nozzle pressures. A new value of the flow characteristic is determined as a function of the measured volume of fluid dispensed during the dispensing cycle to the measured nozzle pressure. During a subsequent dispensing cycle, the control determines the desired nozzle pressures by evaluating the model of flow rate of the fluid through the nozzle as a function of the new value of the flow characteristic. The process of reevaluating the flow characteristic over successive dispensing cycles as a function of measured volumes of fluid dispensed and measured nozzle pressures, and using those updated values to reevaluate the model of flow rate of fluid through the nozzle, is repeated.
