Regarding claim-16. Hayashi discloses wherein: the sensor (8) at each step-skirt interface (Fig.3 and 6) is configured to execute periodic sensing and is further configured to generate signals during the periodic sensing which are receivable and readable by the processor (11), and wherein:
when no object is present at either step-skirt interface, the signals of each sensor are first signals and are reflective of a predetermined length along the balustrades for which each sensor is responsible, when an object is present at either step-skirt interface for less than the predetermined time, the signals of the corresponding sensor deviate from the first signals and persist for less than the predetermined time, and when an object is present at either step-skirt interface for at least the predetermined time, the signals of the corresponding sensor deviate from the first signals and persist for at least the predetermined time (See Embodiment 1, 3, Fig.1, 3-4).
Regarding claim-19. Hayashi discloses a method of operating an entrapment monitoring and detection system (Fig.3-4, 6) of an escalator system (Fig.1) in which a moving step (2) passes by ends of a brush (15 having brushes) of a balustrade (3) at a step-skirt interface, the method comprising:
scanning the step-skirt interface (via sensor 8);
determining whether results of the scanning are indicative of an object at the step-skirt interface; determining whether the results of the scanning are indicative of the object at the step-skirt interface persisting for a predetermined time; and judging that an entrapment is in effect or imminent in accordance with the results of the scanning being indicative of the object at the step-skirt interface and persisting for the predetermined time (See Embodiment 1, Fig.1, 3-4).
Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claim(s) 4-5, 13-14 is/are rejected under 35 U.S.C. 103 as being unpatentable over Hayashi (JP 2008174315) in view of Li (20180029841).
Regarding claim-4-5, 13-14. Hayashi does not explicitly disclose wherein the sensor (8) is a RADAR sensor; wherein the sensor (8) is a camera; wherein the sensor (8) at each step-skirt interface is a RADAR sensor; wherein the sensor (8) at each step-skirt interface is a camera. However, it is just a mere of design and constructional detail of an apparatus in which skilled person in the art can deploy or alternatively provide any suitable sensor which are well known in the art to detect the presence of the object at given location/point as present by Hayashi sensor (8).
Li discloses an escalator system (Fig.1), and also, teaches wherein the sensor (310, Fig.1-3) is a radar sensor, or camera ([0027]).
Therefore, it would have been obvious to the skilled person in the art before the effective filing date of claimed invention to alternatively provide Hayashi system with radar or camera for purpose of detecting the presence of the object as described by Hayashi.
Claim(s) 8-9, 17-18, and 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Hayashi (JP 2008174315) in view of Lou (US 20200239283).
Regarding claim-8, 17. Hayashi does not discloses further comprising light emitting diodes (LEDs) arranged along the balustrade (3) and controllable by the entrapment monitoring and detection system to emit light in response to the processor (11) determining that the sensor senses the object being present at the step-skirt interface for the predetermined time (See Embodiment 1, Fig.1, 3-4). Hayashi lacks LED arranged along the balustrade that emit light when sensor senses the object. However, Hayashi does teach a warning issuing means 13 to warn that object is lodged at step-skirt interface.
Lou discloses an escalator system (Fig.1) and teaches a sensor (5) that emits visible light upon detection ([0058]).
Therefore, it would have been obvious to the skilled person in the art before the effective filing date of claimed invention to alternatively provide Hayashi system with the sensor that emit light as taught by Lou for purpose to allow passengers or technician to easily spot foreign objects that are lodged at the given step-skirt interface while operational control 14 decelerate the escalator for prevention of any injury to passengers.
Regarding claim-9, 18. Hayashi as modified discloses wherein: the processor (11) is further configured to judge that an entrapment incident is in effect or is imminent in accordance with an affirmative determination that the sensor (8) senses the object being present at the step-skirt interface for the predetermined time and to take a mitigation action accordingly, and the mitigation action comprises at least one or more of activating a warning (warning issuing means 13 or emitting light as taught by Lou sensor 5) light to emit a first color, activating the warning light to emit a second color and braking or slowing (decelerating) the escalator system (See Embodiment 1, Fig.1, 3-4).
Regarding claim-20. Hayashi as modified discloses further comprising taking a mitigation action to address the entrapment being in effect or imminent, the mitigation action comprising at least one or more of activating a warning (warning issuing means 13 or emitting light as taught by Lou sensor 5) light to emit a first color, activating the warning light to emit a second color and braking or slowing (decelerating) the escalator system (See Embodiment 1, Fig.1, 3-4).
