Title: A method of controlling heating in a building
Inventor: SCHEU WALTER
IPC: G05D23/19
Filed: 1993-07-30
Abstract: In a method of controlling a sluggish heating and cooling system for buildings, that due to a high heat capacity reacts with delayed temperature changes, the exterior temperature is measured, an average projected temperature value of the exterior temperature based on previously measured exterior temperatures is extrapolated, and the heating and cooling system is switched based on the average projected temperature value. <IMAGE>

Title: Two way rolling sheet trailer cover
Inventor: HUMPHREY KENNETH
IPC: B60J7/08
Filed: 1993-08-27
Abstract: A sheet cover 1 e.g. articulated bulk trailer, that can be rolled open from either side of the trailer enabling it to be loaded from either side without restriction. The cover is releasably secured to the trailer and can be unwound simply from a ground standing position in either direction across the trailer and restrained by strapping 7 to the overhanging leading edges which can be tightened onto the trailer and support poles 2 to tension the sheet covering the trailer prior to transit. Cambered ribs 4 at each end provide rolling guides for the leading edge and ridge poles for winding up and also form a profile for the tensioned sheet. The rear rib has a telescopic strut support 6 to the trailer rear gate to allow tipping and opening of the gate without deformation of the support rib. <IMAGE>

Abstract: A moulded plastic handle and a method of its manufacture, the handle comprising an injection-moulded, rigid, thermoplastic core 11 having an outer sleeve 12 of similar but softer thermoplastic polymer injection-moulded to its surface. A central domed rectangular cavity 13 is formed axially in the core 11 for receiving a similarly shaped tang (23, Fig. 4) of a tool. Preferably the tang is of pressed metal, is of an inverted U-shape, has saw-tooth or ratchet form teeth (24, Fig. 4) on its lower edges and is force-fit in cavity 13.

Title: Actively adjusting and controlling a resonant mass-spring system
Inventor: GARNJOST KENNETH D
IPC: B60G17/018
Filed: 1994-03-21
Abstract: An actively-controlled resonant-type force generator 20 is adapted to be attached to a structure 21, and includes a mass 23 mounted for movement relative to the structure and a plurality of springs 22, 24 operatively arranged between the mass and the structure. A servoactuator (26) is arranged to controllably excite the mass-spring system. The actual force (Fa) transmitted from the mass to the structure is compared with a commanded force (Fc) to produce a force error signal (Fe). The actuator is caused to produce a velocity as a function of the error signal. The gain of the closed force loop is selected so that the resonance of the mass-spring system has an effective damping ratio ( zeta ) greater than about 0.5, and preferably about 0.7. Thus, the mass-spring system will not be substantially resonantly excited by vibrations of the structure near its resonant frequency ( omega n) The actuator may be in series (figs. 1, 2, 6, 7) or in parallel (fig. 8) with the mass and spring or springs and may be hydraulic (figs. 1, 2, 6, 7) or electromagnetic (fig. 8, 9). The mass may be mounted on a level (fig. 16) and the invention has particular application to helicopters (figs. 13 and 14). <IMAGE>

Patent GB-2282468-A (GB)
Title: A fuel controller with air/fuel transient compensation
Inventor: DELOSH ROBERT G
IPC: F02D41/14
Filed: 1994-09-28
Abstract: A fuel control system operates under closed-loop control to sense the oxygen content of the combustion products of an internal combustion engine along with the engine angular velocity and air flow through the intake manifold and to alter the composition of air and fuel combusted by the engine, such that under stable closed-loop control, the air/fuel composition generally oscillates about stoichiometry between a minimum and a maximum value. The rate of fluctuation of the oxygen content of the combustion products is monitored and if the oxygen content does not switch when expected, then a transient change in the exhaust content of the exhaust gas is assumed and a transient response is generated. The transient response comprises the generation of an air/fuel ratio substantially equal in magnitude and time but opposite in direction from the detected transient. After the transient response, periodic fluctuation of the air/fuel ratio between the minimum and maximum values is resumed. <IMAGE>

IPC: B65H5/06
Filed: 1996-05-24
Abstract: A sheet P is guided to the nip a between feed and pinch rollers 30 and 40 by a guide 50, which is pivotal about axis X1, which is itself shiftable in direction X. A spring 58 urges end 53 of the guide 50 into contact with the feed roller 30, and a roller 57 is mounted on the guide 50 and contacts the feed roller 30 to control the contact pressure f at end 53.

Title: Moving objects combined with video matte image display
Inventor: DE HAAN GIJSBERT
IPC: H04N5/262
Filed: 1997-03-22
Abstract: Image data is processed consisting of a first data set representing a polarity of moving objects and a second data set derived from two dimensional video frames. Three dimensional video objects are perceived as moving in three dimensional space in response to a trajectory definition. The trajectories of the moving objects is modified in response to the position of the two dimensional video frames. The modification may be affected in response to a matte or key signal derived from the video images, allowing the foreground video image to be combined with three dimensional moving particles. As described a plurality of moving objects data 602 are defined in a 3-D world space in accordance with a computer algorithm. A matte image data 603 is introduced into a 2-D control plane within said 3-D world space and trajectories of the moving object data which are coincident with the control plane are modified in accordance with the matte image data values. Alternatively the moving object generation sites may be distributed over the matte image and the density of these sites may be made dependent upon the information contained in the matte image data eg more sites from the "body areas of a car" matte image than from the "window areas of a car" matte image. In addition the speed and direction of the moving objects and their rate of generation may be controlled by the matte image data parameters eg intensity or colour.

Title: Digital Broadcasting Receiver
Inventor: OHKUBO TADATOSHI
IPC: H04L27/22
Filed: 1997-04-24
Abstract: It is an object to correct a frequency deviation at the time of reception of a digital signal in which each carrier is subjected to phase modulation and orthogonal frequency division multiplexing (OFDM). A vector of fixed pattern symbols for reference of received carriers is multiplied by a vector of conjugate complex numbers of the defined values for each element. In the result, elements separated by the same numbers forward and backward from an element at a particular carrier frequency are multiplied together and the results are added. The same processing is applied to cases in which the elements of the vectors are mutually shifted by a plurality of elements from a certain correspondence and synchronization control to the broadcasting frequency is provided on the basis of a value which maximizes the absolute value in the results of the addition and the correspondence at that time.

Title: Viterbi decoder for depunctured codes
Inventor: CHOI YOUNG BAE
IPC: G06F11/10
Filed: 1997-06-30
Abstract: A Viterbi decoder for decoding depunctured code comprises a branch metric calculation unit; an add/ comparison/ selection unit; a path metric network; a survivor memory unit; a decoding depth control unit; and a decoded symbol selection unit. The decoding depth control unit outputs a decoding depth control signal by determining a decoding depth having the least bit error rate according to code rates of punctured codes. The decoding depth having the least bit error rate is set to a maximum value of integer times or integer +1 times of each code rate's numerators of the punctured codes within a range of a predetermined decoding depth. Accordingly, the Viterbi decoder recovers the original information without the need to expand the conventional survivor memory required for a trace back process in the system using the puncturing technique.
