Claim Rejections – 35 U.S.C. 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claim(s) 1, 2, 7, 8, 15, 16 is/are rejected under 35 U.S.C. 102(a)1 as being anticipated by Weilguni et al. (2019/0394864).
Regarding Claim 1, Weilguni discloses a device comprising:
a) at least one radiation emitting element (infrared radiation source, paragraph [0003]) configured for emitting a modulated (turned on for a certain pulse duration, paragraph [0004]) thermal
radiation (emits thermal radiation, paragraph [0003]) as a result of its temperature; wherein the radiation emitting element comprises at least one incandescent lamp (incandescent lamp, paragraph [0003]); and
b) at least one electronic circuit (electronic arrangement, abstract) configured for applying a periodic time-dependent voltage (time-dependent control voltage, abstract) to the radiation emitting element (radiation source, abstract), wherein the electronic circuit is configured for controlling one or more of an amplitude, a duty cycle (ON state for a pulse duration, abstract; voltage converter selects a time profile, paragraph [0023]. Noted that the ratio of ON state and OFF state determine the duty cycle) and a frequency of the periodic time-dependent voltage (control input such that coil is constantly turned on and off at a frequency in the range of from 100kHz to 1MHz, paragraph [0050]. Noted the voltage at coil via the control input is feedback to the FB, See fig. 3),
wherein a frequency of the modulated thermal radiation (control input such that coil is constantly turned on and off at a frequency in the range of from 100kHz to 1MHz, paragraph [0050] depend on the applied periodic time-dependent voltage (time-dependent control voltage, abstract. The control voltage is feedback to FB, See fig. 3) controlled by the electronic circuit.
Weilguni discloses that the radiation emitting source (paragraph [0003]) emits thermal radiation (paragraph [0003]) as a temperature of the radiation emitting element. The lamp voltage is based on the time-dependent voltage at the feedback (See Abstract, fig. 3).
In addition, in paragraph [0062], Weilguni teaches three equations about the relationship among lamp voltage, power, and lamp temperature. For example, the time dependent lamp voltage VLP(t) determines lamp power PLP. And the lamp TLP(t) is depend on the lamp power (PLP). Therefore, the temperature of the lamp (radiation emitting element) is dependent on the time-dependent voltage.
Regarding Claim 2, Weilguni discloses the device of claim 1, wherein the electronic circuit is configured for controlling the periodic time-dependent voltage such that the applied periodic time-dependent voltage is unipolar (lamp voltage in a range of from 0.6V to 2.4V. Since it is positive voltage, it means unipolar, paragraph [0059]) and sinusoidal (Weilguni teaches that the voltage at the coil is constantly turned on and off at a frequency in the range of from 100kHz to 1MHz, paragraph [0050]. It is noted that since the output voltage is generated at a frequency, sinusoidal waveform is created)
Regarding Claim 7, Weilguni discloses the device of claim 1, wherein the electronic circuit comprises at least one variable output buck regulator, wherein the buck regulator (buck converter with voltage divider) comprises at least one resister network (R1, R2) (paragraphs [0055], [0056]).

wherein the radiation emitting element comprises at least one incandescent lamp (incandescent lamp, paragraph [0003]), the method comprising:
I) applying at least one periodic time-dependent voltage (time-dependent control voltage, abstract) to the at least one radiation emitting element (radiation source, abstract); and
II) controlling one or more of an amplitude, a duty cycle (ON state for a pulse duration, abstract; voltage converter selects a time profile, paragraph [0023]. Noted that the ratio of ON and OFF state determines the duty cycle), and a frequency of the periodic time-dependent voltage (microcontroller controls buck converter via control input such that coil is constantly turned on and off at a frequency in the range of from 100kHz to 1MHz, paragraph [0050]) with electronic circuits (electronic arrangement, abstract, fig. 3).
