`

`REMARKS
`
`Reconsideration of pending claims 1 - 8 and 10- 37 is requested.
`
`Claim 1 features apparatus for controlling motion of a motor driven element in a
`
`vehicle over a range of motion and for altering that motion when undesirable resistance
`
`to motion is encountered . A sensor measures a parameter of a motor coupled to the
`
`motor driven element that varies in response to a resistance to motion during all or part
`
`of a range of motion of the motor driven element. A memory is used to store a number
`
`of measurement values from the sensor based on immediate past measurements of the
`
`parameter over at least a portion of a present path of travel of the motor driven element
`
`through its range of motion. A controller coupled to the memory determines whether to
`
`de-activate the motor based on a most recent sensor measurement of the parameter
`
`and the immediate past measurement values stored in the memory as the motor driven
`
`element moves over its range of motion . A controller interface coupled to the motor
`
`alters motion of the motor driven element in response to a determination made by the
`
`controller.
`
`The controller featured in claim 1 performs its collision detection based on real
`
`time data obtained during a present run of the window or panel. Unlike the invention
`
`featured in claim 1, the Jones et al system disclosed in US 4,831,509 uses training data
`
`stored by the control during a training run to signal a collision between a door and an
`
`obstacle and therefore neither shows nor suggests the structure of claim 1.
`
`At column 3, line 17, Jones et al notes, "In order to determine a door travel
`
`characteristic the processing means samples the time taken for the door curtain to
`
`travel a fixed distance and therefrom determines changes in the speed of the door." At
`
`column 4, line 49 Jones et al states "As stated above the stored running average of
`
`peak speed changes for a segment is regularly compared with the calculated peak
`
`speed change for the same segment on a present run of the door. If this new value
`
`exceeds the stored value, the door controller will consider an obstruction to have been
`
`detected in the travel path of the door."
`
`These two statements from columns 3 and 4 must be interpreted in light of the
`
`December 13th, 2006
`
`12
`
`

`

`Jones et al definition of a 'segment' found
`
`at column 3, line 20. The Jones et al
`
`system works "by notationally dividing the door travel into a plurality of segments and
`
`further sub-dividing each segment into a plurality of secto[r]s (sic) and producing a
`
`running average of peak speed changes for each sector."
`
`Returning to the Jones et al collision detection scheme defined at column 4 and
`
`assume a collision is encountered sometime during a run, i.e. during a one way
`
`traversal by the door in its travel path. Specifically, assume the time it takes to traverse
`
`a sector (recall multiple sectors make up a segment) is dramatically greater than
`
`previously encountered. Jones et al assumes such dramatic change in speed is due to
`
`a collision.
`
`The Jones et al control compares the dramatic speed change of that sector
`
`(sector x, for example) with an average peak speed change for the segment (16
`
`consecutive sectors) in which sector xis located. The controller can not calculate the
`
`average peak speed change for the segment containing the sector x on a real time
`
`basis as featured in claim 1. All sectors within the segment have not been encountered
`
`or traversed. Stated another way, the Jones et al collision detected must be based on
`
`old data. Jones et al must be using old data from a prior door run (sometimes referred
`
`to as a training run) and hence neither shows nor suggests applicants invention .
`
`The advantages achieved through practice of the invention are significant.
`
`Assume weeks go by between operation of a vehicle sunroof for example. The
`
`temperature could have changed dramatically. The roof might have been closed with
`
`the vehicle parked during its last run sequence and therefore the drag encountered due
`
`to wind resistance was different. On the present run, the sunroof is closed as the car is
`
`traveling down the highway at a reasonable rate and the temperature is much higher.
`
`How will the controller react if it is relying on old data? The Jones et al system must use
`
`old data and hence may not react properly. This fact highlights the fact that a system
`
`satisfactory for use as a garage door control may not work as effectively in a motor
`
`vehicle control for a window or panel of a motor vehicle. Jones et al neither anticipates
`
`nor renders obvious the subject matter of claim 1 and this claim is patentable.
`
`December 13th, 2006
`
`13
`
`

`

`New claim 36 depends on allowable claim 1 and is also allowable. This claim
`
`features the apparatus of claim 1 wherein the immediate past measurements used in
`
`determining a threshold are taken within a forty millisecond interval prior to the most
`
`recent sensor measurement. Since Jones et al relies on old data observed during an
`
`old run or sequence, there is no suggestion of this feature and therefore this claim is
`
`patentable.
`
`Claim 2 features a method for controlling motion of a motor driven element in a
`
`vehicle over a range of motion and for altering the motion when undesirable resistance
`
`to the motion is encountered. The method is performed by measuring a parameter of a
`
`motor coupled to the motor driven element that varies in response to a resistance to
`
`motion during all or part of a range of motion of the motor driven element by taking a
`
`multiplicity of measurements as the motor moves the motor driven element over its
`
`range of motion. A number of measurement values are stored based on measurements
`
`of the motor parameter over at least a portion of its range of motion. If the parameter is
`
`determined to be outside a parameter range based on previous stored measurement
`
`values as the motor driven element moves over its range of motion, the method of claim
`
`2 alters motion of said motor driven element.
`
`Claim 2 was rejected in the last office action as being anticipated under 35 USC
`
`102(b) on the basis of Jones et al (US 4,831 ,509).
`
`The Court of Appeals for the Federal Circuit has held that language found in the
`
`preamble of a claim that is also included in the body of the claim limits the claim "by
`
`virtue of its inclusion." Catalina Marketing, 62 USPQ2d at 1787; see also British
`
`Telecommunications v. Prodigy Communs., 217 F.Supp.2d 399,413 (S.D.N.Y. 2002)
`
`(finding that a preamble term limited the claim because it was also found in the body of
`
`the claim). In the Telecommunications decision it was held that the preamble provided
`
`structure to the claim body, a "central computer" being the terms at issue. The
`
`Telecommunications decision differs somewhat from Catalina Marketing where the
`
`claim language was concentrated on use, reciting "a plurality of free standing terminals
`
`located at predesignated sites such as consumer stores". Catalina Marketing, 62
`
`December 13th, 2006
`
`14
`
`

`

`USPQ2d at 1783 (emphasis added on
`
`terms at issue). The Federal Circuit even
`
`articulated such by identifying the claim language as defining an intended use, stating,
`
`"the location of the terminals in stores merely gives an intended use for the claimed
`
`terminals." /d., at 1786-87. But, the Court held the same language in claim 25 limited
`
`the claim because it was found the language in both the preamble and body of the
`
`claim.
`
`In the present instance claim 2 calls for, in part a motor driven element in a
`
`vehicle. Whether this term is interpreted as a use or a structure, weight must be given
`
`to its recitation since it is used again in the claim body, i.e. the recitation of the motor
`
`driven element is found throughout the claim. Since Jones et al neither shows nor
`
`suggests a motor driven element in a vehicle, this claim is not properly rejected either
`
`as being anticipated or rendered obvious by Jones et al. Stated another way a prima
`
`facie basis of rejection is not found in Jones et al.
`
`Claim 2 also recites measuring a parameter of a motor coupled to the motor
`
`driven element. Turning to Jones et al, at column 3, line 7 , Jones et al states that "the
`
`door curtain position relative to the door opening is obtained from an encoder coupled to
`
`the door drum. (emphasis added) Pulses are provided to the encoder from
`
`optoelectronic sensors appropriately placed or positioned in relation to a set of spinning
`
`blades coupled to the drive means for the roller door."
`
`In Jones et al the speed and position of the door increase when lowered due to
`
`the added affect of gravity and the speed and position decrease as the door is raised.
`
`Jones teaches a door position encoder "for providing signals indicative of the position of
`
`the door curtain relative to the door opening". column 1 line 53 of Jones et al, but there
`
`is no teaching or suggestion of measuring a parameter of a motor coupled to a motor
`
`driven element. By noting that the motor load "is dependent on the position of the door"
`
`as a criticism of using motor load monitoring devices, Jones et al explicitly teaches
`
`away from measuring a parameter of the motor and using that parameter to determine if
`
`the parameter is outside a range as featured in claim 2.
`
`For the foregoing reasons, claim 2 is not anticipated nor rendered obvious in the
`
`December 13th, 2006
`
`15
`
`

`

`prior art patent to Jones et al and is
`
`therefore allowable. Claims 3- 5 depend
`
`on allowable claim 2 and are also allowable.
`
`Claim 6 features apparatus for controlling activation of a motor coupled to a
`
`motor vehicle window or panel for moving the window or panel along a travel path. The
`
`panel or window movement is stopped in the event an obstacle is encountered by the
`
`window or panel. The apparatus includes a sensor that senses movement of the
`
`window or panel and provides a sensor output signal related to a speed of movement of
`
`the window or panel. A switch controls actuation of the motor by providing an energiz(cid:173)
`
`ation signal and a controller has an interface coupled to the sensor and the switch to
`
`control energization of the motor.
`
`The controller of claim 6 implements real time collision sensing better suited
`
`(than Jones et al) to use with a controller moving a window or panel mounted in a motor
`
`vehicle. The exemplary controller:
`
`i) monitors movement of the window or panel by monitoring a signal from the
`
`sensor related to the movement of the window or panel;
`
`ii) adjusts an obstacle detection threshold in real time based on immediate past
`
`measurements of the signal sensed by the sensor to adapt to varying conditions
`
`encountered during operation of the window or panel;
`
`iii) identifies a collision of the window or panel with an obstacle due to a change
`
`in the signal from the sensor that is related to a change in movement of the window or
`
`panel by comparing a value based on a most recent signal from the sensor with the
`
`obstacle detection threshold; and
`
`iv) outputs a control signal to the switch to deactivate the motor in response to a
`
`sensing of a collision between an obstacle and the window or panel.
`
`As discussed above, the Jones et al patent neither shows nor suggests the
`
`italicized features of claim 6 and accordingly this claim is allowable.
`
`Claims 7, 8, 10, 11 and 37 depend from allowable claim 6 and are also allowable.
`
`The comments above regarding new claim 36 are also applicable to claim 37.
`
`Claim 12 features apparatus for controlling activation of a motor for moving an

`

`

`object along a travel path and de-activating the motor if an obstacle is encountered by
`
`the object. A movement sensor monitors movement of the object as the motor moves
`the object along a travel path. A switch controls energization of the motor with an
`energization signal and a controller includes an interface coupled to the switch for con(cid:173)
`
`trollably energizing the motor. The interface also couples the controller to the
`
`movement sensor for monitoring signals from said movement sensor. The controller
`
`has a stored program that:
`
`i) determines motor speed of movement from an output signal from the
`
`movement sensor;
`
`ii) calculates an obstacle detect threshold based on motor speed of movement
`
`detected during a present run of said motor driven element;
`
`iii) compares a value based on currently sensed motor speed of movement with
`
`the obstacle detect threshold; and
`
`iv) outputs a signal from the interface to said switch for stopping the motor if the
`
`comparison based on currently sensed motor movement indicates the object has
`
`contacted an obstacle.
`
`Jones et al neither shows nor suggests calculating an obstacle detect threshold
`
`based on motor speed of movement detected during a present run of the motor driven
`
`element and for this reason claim 12 is allowable.
`Claims 13- 18 depend on allowable claim 12 and are also allowable.
`Claim 19 features apparatus for controlling activation of a motor for moving a
`
`window or panel along a travel path and de-activating the motor if an obstacle is
`
`encountered by the window or panel. A sensor senses movement of a window or panel
`
`along a travel path and a switch controls energization of the motor with an energization
`
`signal.
`
`Claim 19 also includes a controller coupled to the switch for controllably
`
`energizing the motor and having an interface coupling the controller to the sensor and to
`
`the switch. The controller implements decision making logic for:
`
`i) monitoring a signal from the sensor;

`
`

`

`ii) calculating a real time
`
`obstacle detect threshold based on the
`
`signal that is detected during at least one prior period of motor operation during
`
`movement along a present or current path of travel of said window or panel;
`
`iii) comparing a value based on a currently sensed motor parameter with
`
`the obstacle detect threshold; and
`
`iv) stopping movement of the window or panel by controlling an output to
`
`said switch th
