Title: Telephone call billing system
Inventor: ROSINSKI RICHARD R
IPC: H04M15/00
Filed: 1993-07-26
Granted: 1997-01-14
Abstract: The cost of a telephone toll call is shared by arranging the billing system of the telephone toll carrier to permit sharing of  the  period  cost  for  at least  one indivisible time period of a toll call. Accordingly, at least a portion of the period cost associated with at least one of the indivisible time periods of a toll call is assigned to both the terminating and originating subscribers, so that each subscriber to the toll call is billed for a portion of the total basic cost incurred for each of those indivisible periods of time over which it is agreed that the period costs will be shared. Anauthorization signal, indicating that the subscriber who would not have shared in the period costs for any indivisible period if the call had the call been placed as in the prior art--typically the terminating subscriber--agrees to accept his share of the period costs, may be required before any period cost sharing periods can occur.

Title: Energy absorbing roadside crash barrier
Inventor: GERTZ DAVID C
IPC: B60R19/36
Filed: 1993-07-29
Granted: 1997-03-18
Abstract: An  energy  absorbing  roadside  crash  barrier includes a scissors linkage having first and second ends. The  scissors  linkage  is  movable  between  an  extended position and a collapsed position.  A mounting element is coupled to the first end of the scissors linkage to mount the scissors linkage to a roadside obstacle.  Deformable energy absorbing elements are mounted to  the  scissors linkage and positioned such that movement of the scissors linkage from  the  extended  to  the  collapsed  positions deforms  the  energy absorbing  elements,  and the  energy absorbing elements thereby progressively resist collapse of the scissors linkage.  A tension member is secured to the scissors linkage to apply a restraining force to hold the scissors linkage in the extended position, until forces tending to collapse the linkage exceed a pre-set range of values.

Granted: 1997-07-22
Abstract: A swing-tongue harvester (10) has a hydraulically controlled pulling tongue (30) that can be operated from the tractor seat to change the lateral position of the machine relative to the towing tractor (36), notwithstanding the presence of a mechanical drive line (90) which extends along the tongue (30) and branches down to a gearbox (116) carried by the header (50) for driving the operating components of the header (50). Telescoping steering linkage (138) between the swing tongue (30) and the gearbox (116) causes the gearbox (116) to swing responsively with the tongue (30) when the tongue is swung to any of its angular positions, thus keeping the input shaft (114) of the gearbox (116) oriented properly toward the driveline (90) along the tongue (30). The connection points for the steering linkage (38) between the tongue (30) and the gearbox (116) are such that a telescoping section (106) of the driveline (90) bridging the tongue (30) and the input shaft (114) of the gearbox (116) has equal angles maintained at its universal joints (104, 110) at opposite ends of the telescoping section (106) to reduce unequal loading at those locations. Specifically configured impeller plates (186) associated with the left and right, endmost rotary cutting units (172) on the cutter bed of the header (50) assist in proper delivery of the cut materials rearwardly into the discharge opening (65) of the header (50).

Abstract: A vibration isolator (10) has four fluid-filled variable volume toad-bearing chambers (32a-d), with two arranged on one side of a core (20) and the ether two on the other side. The core (20) and chambers (32a-d) are contained within a frame (12), with the chambers (32a-d) extending between the core (20) and the frame (12), so that vibrating the core (20) axially compresses or ex-tends the chambers (32a-d). Diagonally opposite pairs (32a-d, 32b-c) of chambers (32a-d) are each connected with a separate fluid track (70, 72), and the two fluid tracks (70, 72) may be tuned to have different resonant frequencies or the same resonant fre-quency. The chambers (32a-d) are defined by elastomeric bodies (24a-d) which may be reinforced using a tubular shaped reinfor-cing element (26a-d) adjacent to the chamber (32a-d), to help contain the pressures within the chamber (32a-d) without materially increasing the compression strength of the elastormeric bodies (24a-d). A  fluid expansion chamber (50) communicates with the fluid envelope of the chambers (32a-d) and tracks (70, 72) through porous flow restriction elements (64) which allow flow to or from the expansion chamber (50) in response to temperature changes of the fluid but snub significant flow to or from the expand-sion chamber (50) which may otherwise be caused by subjecting the isolator (10) to vibrations.

Abstract: A method (30) for measuring and quantifying clutter, and target detection and tracking systems (10) that employs wavelet-based clutter quantification to generate a clutter number and a signal-to-clutter ratio derived therefrom to achieve improved target detection performance. The method (30) processes video signals representative of an image scene (14) containing a target (15) and background clutter (16) to provide for more accurate tracking of the target (15) by a tracker(s) (21). The method (30) comprises processing (31) the video signals to compute a wavelet clutter number,processing (32) the video signals to compute a signal-to clutter ratio using the wavelet clutter number, and generating (33) a pointer to a lookup table that sets parameters and selects the tracker (21) that is to be used to track the target (15) based upon the computed signal-to clutter ratio. The target detection and tracking system (10) tracks a target (15) located in an image scene (14) containing clutter (16). The system (10) comprises a sensor (11) for generating video signals representative of the image scene (14) that contains the target (15) and the background clutter (16). A tracking computer (12) is coupled to the sensor (11) that comprises a tracker(s) (21) that implement predetermined tracking algorithms that are designed to track different types of targets (15). A wavelet-based signal-to-clutter processor (20) is coupled between the sensor (11) and each of the tracker(s) (21) for processing the video signals to compute the wavelet clutter number and the signal-to clutter ratio using the wavelet clutter number, and for generating a pointer to a lookup table that sets parameters and selects a particular tracker (21) or tracking algorithm that is to be used to track the target (15) based upon the computed signal-to clutter ratio. A display monitor (13) may be coupled to the tracker(s) (21) for viewing the tracked target (15) and the image scene (14). The computed signal-to clutter ratio corresponds to target contrast divided by the clutter number, where the contrast is defined as the difference between a peak gray level (P~) of the target (15) and a local background gray level (µb).

Title: Pleated blinds
Inventor: RALTON DAVID
IPC: E06B9/24
Filed: 1995-08-10
Granted: 2007-02-06
Abstract: A pleated blind is disclosed including a head rail, a bottom rail and an expandable and collapsible shade extending between them and divided up into a plurality of pleats by fold lines. A row of apertures passes through each pleat to permit passage of a supporting cord. The supporting cord consists of a central yarn and a series of equally spaced polymeric rungs. The rungs are spaced at equal intervals along the cord, the spacing between the rungs being substantially equal to the maximum distance between the head rail and the bottom rail divided by the number of pleats in the shade. In this way, the rungs, which are of sufficient length to span the sides of the apertures, will support their respective pleats and prevent the pleats from opening up too widely, thus ensuring that the pleat spacing remains substantially even.
