[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] See also Figure 1 , Figure 2 and Figure 3The present application provides a wearable physiotherapy device 100, including a control component 114, a wear pad 101, and a cable 109 connecting the control component 114 and the wear pad 101. The wear pad 101 includes an outer layer 125, an intermediate layer 127, and an inner layer 102. Fasteners 202 are provided at both ends of the outer layer 125 to relatively fix the wear pad 101 to the area to be treated (such as the face, waist or arm) so that the user can use it more stably and reliably. The intermediate layer 127 is provided between the inner layer 102 and the outer layer 125.

[0043] The inner layer 102 is suitable for contacting with the user's skin, and is provided with a plurality of detection positions 107 and a plurality of stimulation positions 103 respectively located between the plurality of detection positions 107. The wearable physiotherapeutic device 100 further includes a plurality of stimulation elements 104, a plurality of optical fibers 106, and an optical sensor 206. The stimulation elements 104 are installed at the stimulation positions 103. Each optical fiber 106 has a first optical endpoint 108 and a second optical endpoint 133. The first optical endpoint 108 is located in the detection position 107. The optical sensor 206 is used to receive an optical signal transmitted from the first optical endpoint 108 to the second optical endpoint 133. A through hole 129 is provided on the stimulation site 103 relative to the stimulation element 104, and the detection site 107 is arranged at intervals or overlaps with the stimulation site 103. In this embodiment, at least one stimulation site 103 is arranged in the area surrounded by multiple detection sites 107, and at least one detection site 107 is arranged in the area surrounded by multiple stimulation sites 103. The first optical endpoint 108 corresponds to the detection site 107 one by one, so that the stimulation element 104 and the first optical endpoint 108 can be evenly arranged in each part, and the user's skin data can be collected and treated as much as possible. The stimulation element 104 can pass through the inner layer 102 through the through hole 129 and directly contact the user's skin for treatment.

[0044] The stimulation element 104 is a combination of one or more of a phototherapy light source, an irradiation source, a heating element, a cooling element, a vibration element, an ultrasonic generator, and an electrode. When the stimulation element 104 is a phototherapy light source, the stimulation element 104 may be composed of a light emitting diode and a laser, and select or switch between a pulse mode and a continuous mode; when the stimulation element 104 is an irradiation source, the stimulation element will emit electromagnetic radiation; when the stimulation element 104 is a vibration element, the stimulation element 104 may be a vibration head composed of a motor; when the stimulation element 104 is a heating element, the stimulation element 104 may be a combination of one or more of a metal heating element, a ceramic heating element, a semiconductor heating element, a thick film heating element, a polymer-based heating element, etc.; when the stimulation element 104 is a cooling element, the stimulation element 104 may be a thermoelectric cooler, also known as a Peltier heat pump; when the stimulation element 104 is an ultrasonic generator, the stimulation element 104 may be composed of a quartz crystal fused to a metal plate. Quartz crystals can potentially generate ultrasound waves due to the piezoelectric effect, and ultrasound therapy can be used for applications such as treating chronic pain, improving blood circulation, and tissue repair.

[0045] In the case where the stimulation element 104 is an electrode, the stimulation element 104 can be embodied as an open conductor. The stimulation element 104 is capable of providing transcutaneous electrical nerve stimulation (TENS), electronic muscle stimulation (EMS), and microcurrent electrotherapy (MET) to the user's body. TENS therapy uses low-voltage electric current to relieve pain. The electrical pulses are delivered through electrodes placed on the surface of the user's body. The electrodes are placed at or near the nerve where the pain is located or at certain known trigger points. EMS therapy is similar to TENS therapy, except that EMS is applied to key muscle groups rather than being widely used. The electrical signals in MET cause certain muscles to contract and tighten. In addition, the electrical pulses in EMS therapy are stronger than those in TENS therapy. In contrast, the current amplitude used by MET is less than 1 mA and the frequency is 0.5 Hz, which can be used to treat pain.

[0046] In this embodiment, the wearable physiotherapy device 100 also includes a light source 252, and the light emitted by the light source 252 is incident on the optical fiber 106 from the second optical endpoint 133, emitted through the first optical endpoint 108, and used to form an incident light signal that irradiates the skin at a corresponding position; and the first optical endpoint 108 is used to receive the incident light signal reflected by the skin at a corresponding position to form a reflected light signal, and the reflected light signal is emitted from the second optical endpoint 133 through the optical fiber 106 to the optical sensor 206.

[0047] The light source 252 is configured to provide incident light for sensing applications, deploying techniques involving the use of interferometers, optical coherence tomography (OCT), Raman scattering, fluorescence spectroscopy, fiber Bragg gratings, confocal microscopy, etc. In embodiments involving the use of the light source 252, the light source 252 is configured to provide incident radiation to the plurality of optical fibers 106 through the plurality of respective second optical endpoints 133. In addition, the electromagnetic radiation received by the optical sensor 206 is reflected radiation from the plurality of first optical endpoints 108.

[0048] Light source 252 can be selected from several different available structures. For example, LED can be used for light source, because LED can produce a wide range of wavelengths, and has higher durability and lower manufacturing and operating costs. Another possible choice of light source 252 may be super luminescent diode (SLD) with relatively wider spectral bandwidth and higher output power. SLD is related to sensors based on Raman scattering and Brillouin scattering. Lasers used as light sources provide incident beams with very high coherence for interferometric sensors and fiber Bragg grating sensors. Halogen lamps or xenon lamps can be used for fluorescence-based sensors. Ultraviolet (UV) light sources, such as excimer lasers or mercury lamps, can be used as applications involving biomolecule detection.

[0049] The inner layer 102 is also provided with a plurality of installation slots 131, one end of which is a detection position 107. The optical fiber 106 is arranged in the installation slot 131, and the middle part of each optical fiber 106 is bound to form an optical cable 122. The optical sensor 206 is installed in the control component 114, and the second optical end point 133 extends into the control component 114. The middle part of each optical fiber 106 is bound together with the cable 109, and the optical cable 112 is in a tapered structure 135 near the second optical end point 133. The tapered structure 135 converges the optical fiber 106 to facilitate connection with the control component 114. This arrangement makes the overall structure thinner and lighter, reduces the load-bearing burden when the user wears it, and is not easy to fall off.

[0050] Multiple optical fibers 106 transmit electromagnetic radiation signals that carry information about at least one physiological parameter associated with the user's skin (such as temperature, pressure, strain, and other visual skin abnormalities). For example, the intensity of the electromagnetic radiation may be affected by changes in temperature, pressure, or strain. Similar to intensity, the phase of the electromagnetic radiation may be sensitive to environmental changes such as vibrations or sound waves. The inherent polarization of electromagnetic radiation may be affected by external factors such as magnetic fields or electric currents. Some optical fiber materials exhibit color changes or wavelength changes when exposed to specific chemicals or temperature changes. In addition, the transmission time of the electromagnetic radiation within the multiple optical fibers 106 is also affected by changes in strain, pressure, etc.

[0051] In this regard, the plurality of optical fibers 106 can be further adapted in several ways to amplify the effects that the physiological parameters may have on the plurality of optical fibers 106. For example, doping the optical fiber 106 material with certain known dopants will allow the plurality of optical fibers 106 to recognize specific chemical molecules and temperature changes. Etching or removing a portion of the cladding material of the plurality of optical fibers 106 will enhance its sensitivity to changes in pressure and strain. In addition, a microcavity structure can be provided in the plurality of optical fibers 106, and these optical fibers 106 can be configured to capture light capable of generating a resonant cavity. The resonant cavity is sensitive to changes in temperature. In addition, the plurality of first optical endpoints can be provided with a parameter-sensitive coating, for example, a thermo-dominant fluorescent coating that is sensitive to one or more physiological parameters of the user. It should be noted that the wearable physiotherapy device 100 is made of a flexible material, that is, the inner layer 102, the outer layer 125 and the middle layer 127 are all made of a flexible material, so that during use, it can fully fit the user's skin, improve the therapeutic efficacy, and at the same time improve the comfort of the user in wearing and using. Among them, the inner layer 102 can be composed of a skin-friendly flexible transparent material, such as hydrogel, polyurethane, silicone, polyethylene naphthalate, etc. The outer layer 125 can be opaque to prevent radiation leakage, and can be composed of knitted fabrics, silk, polydimethylsiloxane (PDMS), hydrogel, polyurethane, silicone, polyethylene naphthalate, etc. The middle layer 127 can be composed of a conductor material, such as copper, aluminum, nickel, deposited on a polymer such as polyimide (PI), polyester (PET), polyethylene naphthalate, etc. In addition, epoxy resins and pressure-sensitive adhesives can be used to bond these layers, and a cover layer can be provided on the deposited conductor layer to prevent mechanical and / or chemical damage and / or wear of the conductor layer.

[0052] Please continue to combine Figure 4 The control component 114 includes an optical sensor 206, a user interface 116, an indication unit 118 and a control module 204. The control module 204 includes a processor 254, a memory unit 256 and a communication interface 258. The user interface 116 is used to manually control function switching, and the indication unit 118 is used to display audio-visual information such as device status and operating parameters. The control module 204 is connected to the optical sensor 206, the user interface 116 and the indication unit 118 for signal processing and network communication with external devices.

[0053] It is particularly noted that the external device is a user computing device 210 , which can be selected from a group consisting of a smart phone, a tablet computer, a laptop computer, etc. In addition, the user computing device 210 is configured to communicate with the control module 204 of the control component 114 through the communication network 208 .

[0054] The user interface 116 can be used to manually control function switching, such as switching the function of the wearable physical therapy device 100, selecting between different predefined operating modes, increasing or decreasing the intensity of the treatment provided, broadcasting a media access control (MAC) address for connecting to the user computing device 210, etc. In this regard, the user interface 116 can be embodied as a touch screen (resistive or capacitive), a single control button, or a group of control switches. The indication unit can be embodied as a display screen, an LED and / or a speaker unit, and provide the user with audiovisual information about several operating parameters of the wearable physical therapy device 100. The operating parameters can be selected from the group consisting of the current state of the wearable physical therapy device 100 (on, off or standby), the operating mode (continuous or pulsating), the type of treatment provided (heating, cooling, irradiation, vibration massage or a combination thereof), the treatment time (elapsed time or remaining time) and the charging state of the battery driving the wearable physical therapy device 100.

[0055] In this embodiment, the wearable physiotherapy device 100 further includes a storage device 260, and the control module 204 is connected to the storage device 260 via the communication interface 258. The storage device 260 is used to store static and dynamic data received or generated by the control module 204. The storage device 260 can be set in the control component 114 or separately set outside, which is not limited here.

[0056] The processor 254 is connected to the storage device 260, the light source 252, the optical cable 112 and the optical sensor 206 through the communication interface 258 to process the signal received by the optical sensor 206, access the position data stored in the storage device 260, and control the light source 252 and signal transmission.

[0057] See also Figure 5 , Figure 6 and Figure 7 ,in, Figure 5 This is a front view of the second embodiment of the wearable physiotherapy device 300. Figure 63 is a front view of the third embodiment of the wearable physiotherapy device 350. It is explained here that the wearable physiotherapy device 100, 300 or 350 can be a mask, a belt or an armband, depending on the specific part of the human body to be treated. The difference from the first embodiment is that the overall shape of the wear pad 301 of the second and third embodiments is different. Since it is used for a belt instead of a mask, the overall square structure is more suitable for the waist or arm of the human body. The wearable physiotherapy device 300 also includes a control component 351, a wear pad 301 and a cable 309 connecting the control component 351 and the wear pad 301. The wear pad 301 includes an outer layer 325, an intermediate layer 327 and an inner layer 302. Fasteners 342 are provided at both ends of the outer layer 325 for relatively fixing the wear pad 301 to the area to be treated (such as the face, waist or arm) so that it is more stable and reliable during use. The intermediate layer 327 is arranged between the inner layer 302 and the outer layer 325.

[0058] The inner layer 302 is provided with a plurality of detection positions 307, a plurality of stimulation positions 303 respectively located between the plurality of detection positions 107, and a mounting slot 331. The wearable physiotherapy device 300 further includes a plurality of stimulation elements 304, a plurality of optical fibers 306, and an optical sensor 360. The stimulation elements 304 are installed at the stimulation positions 303. Each optical fiber 306 has a first optical end point 308 and a second optical end point 333. The first optical end point 308 is located in the detection position 307. The optical sensor 306 is used to receive an optical signal transmitted from the first optical end point 308 to the second optical end point 333. A through hole 329 is provided on the stimulation site 303 relative to the stimulation element 304, the detection site 307 is arranged at intervals or overlapped with the stimulation site 303, one end of the installation slot 331 is the detection site 307, the optical fiber 306 is arranged in the installation slot 331, the first optical end point 308 is arranged in the detection site 307 and connected to the optical fiber 306, the optical fiber 306 transmits the signal collected by the first optical end point 308 to the control component 351, and after analysis and processing, controls the working state of the stimulation element 304. At least one or more stimulation sites 303 are arranged to overlap with the detection site 307, so that the stimulation elements 304 and the first optical end point 308 can be evenly arranged in each part, so as to ensure that the user's skin data is collected and treated as much as possible. The stimulation element 304 can pass through the inner layer 302 through the through hole 329 and directly contact the user's skin for treatment.

[0059] In this embodiment, similarly, the wearable physiotherapy device 300 is made of a flexible material, that is, the inner layer 302, the outer layer 325 and the middle layer 327 are all made of a flexible material. The cable 309 also includes a second optical end point 333, which is arranged at the other end of the optical fiber 306 relative to the first optical end point 308 and is arranged in the control component 351. The control component 351 includes an optical sensor 360, a user interface 354, an indication unit 318 and a control module 356, and the control module 356 includes a processor 362, a memory unit 366 and a communication interface 368. Among them, the user interface 354 is used for manually controlling function switching, the indication unit 318 is used for displaying audio-visual information such as device status and operating parameters, and the control module 356 is connected to the optical sensor 360, the user interface 354 and the indication unit 318 for signal processing and network communication with external devices.

[0060] Likewise, the external device is a user computing device 210 , which may be selected from a group consisting of a smartphone, a tablet computer, a laptop computer, etc. In addition, the user computing device 210 is configured to communicate with the control module 204 of the control component 114 via the communication network 208 .

[0061] Similarly, the wearable physiotherapy device 300 also includes a light source 364, and the light emitted by the light source 364 is incident on the optical fiber 306 from the second optical endpoint 333, emitted through the first optical endpoint 308, and used to form an incident light signal that irradiates the skin at a corresponding position; and the first optical endpoint 308 is used to receive the incident light signal reflected by the skin at a corresponding position to form a reflected light signal, and the reflected light signal is emitted from the second optical endpoint 333 through the optical fiber 306 to the optical sensor 306.

[0062] In this embodiment, the control component 351 includes a housing 370, a user interface 354, a circuit board 356 and a rechargeable or replaceable battery 358 installed in the housing 370, a processor 362, a storage unit 366, an optical sensor 360, a light source 364 and a communication interface 368, and the communication interface 368 can also be used as a wired charging port in the battery 358. The optical sensor 360 is installed in the housing 370, and the battery 358 and the optical sensor 360 are electrically connected to the circuit board 356; the wearable physiotherapy device 300 or 350 also includes a cable 309 electrically connecting the circuit board 356 and the stimulation element 304.

[0063] It is specially noted here that the difference between the third embodiment and the second embodiment lies in the different layouts of the stimulation position 303, the detection position 307 and the installation slot 331. In order to facilitate users to perform more efficient skin treatments, the stimulation position 303 and the detection position 307 are distributed as evenly as possible at various positions of the inner layer 302. Therefore, the specific layout is not limited here. In other embodiments, the layout schemes may also be different from those of the second and third embodiments.

[0064] Please continue reading Figure 8 and Fig. 9 , the optical cable 312 is configured to be illuminated by a light source 364, and the optical sensor 360 is configured to receive reflected radiation from a facial area 402 of the user. The facial area 402 has some lesions and abnormalities 404, such as lumps, cracks, redness, freckles, etc. Such lesions and abnormalities can cause local strain and increased pressure. In addition, red will have a darker color feature than the area surrounding it. In some lesions, the local temperature may be slightly higher due to an inflammatory response. Therefore, the light reflected by the lesions and abnormalities will change in intensity, polarization, phase, transit time, etc. when compared with a reference beam. The above changes can then be captured by the optical sensor 360.

[0065] Arm region 412 includes several lesions and abnormalities 414. Lesions and abnormalities 414 may exhibit similar effects to those exhibited by the lesions and abnormalities on incident sensing beam 404. In several embodiments, light source 364 may not be required, and illumination provided by ambient conditions may be sufficient to generate reference and sensing beams.

[0066] See also Fig.10 and Fig.11 , Fig.10 A plurality of respective second optical end points 333 of a plurality of optical fibers 306 are shown, bundled as light beams 312, impinging reflected radiation onto an optical sensor 360. The optical sensor 360 is embodied as a matrix of material elements that may be sensitive to, for example, intensity, phase, polarization, wavelength shift, transit time, or several different combinations thereof. The same principles will also apply to the optical sensor 206.

[0067] The processor 254 of the control module 204 of the first embodiment or the processor 362 of the second embodiment respectively determines the radiation characteristics of the electromagnetic radiation received by the optical sensor 206 or 360. For example, according to the intensity, phase, polarization, wavelength shift, transmission time, etc., each element of the optical sensor 206 or 360 will display a related characteristic response, which can be converted into a related electrical signal and transmitted to the processor 254 or the processor 362 respectively.

[0068] In addition, the processor 254 or the processor 362 when executing the machine-readable instructions can access a position database stored in the storage device 260 or 366. The position database is envisioned to include a plurality of first predefined position coordinate sets of a plurality of respective sensing locations 107 or 307, respectively, and a plurality of second predefined position coordinate sets of a plurality of respective stimulation locations 103 or 303, respectively, with respect to a reference coordinate system. The reference coordinate system can be selected from a group consisting of a Cartesian coordinate system, a polar coordinate system, a spherical coordinate system, and a cylindrical coordinate system.

[0069] The position database may also include a plurality of element position coordinate sets of the optical sensor 206 or 360, respectively. In addition, a mapping may be provided between a plurality of first predefined position coordinate sets and a plurality of element position coordinate sets, so that radiation signatures determined from a plurality of elements may be assigned to a plurality of sensing locations 107 or 307, respectively.

[0070] Fig.11 206 or 360. Each cell in the matrix indicates a sensing location. The radiation characteristics may correspond to intensity, phase shift, wavelength shift, transit time, polarization, etc. depending on the type of optical sensor used and the type of analysis technique used. The processor 254 or processor 362 determines at least one physiological parameter, such as local temperature, pressure, strain, visual abnormality, etc. From the determined radiation characteristics, each of the plurality of first position coordinate sets indicating a plurality of respective sensing locations 107 or 307 is corresponded. For example, at least one physiological parameter may be determined using one or more analysis techniques deploying interferometers, fiber Bragg gratings, confocal microscopy, optical coherence tomography (OCT), fluorescence spectroscopy, Brillouin scattering, and Raman scattering. In addition, the processor 254 or processor 362 may utilize a machine learning (ML) algorithm in combination with historical reference data for determination of artificial intelligence (AI) based on at least one physiological parameter.

[0071] The processor 254 or the processor 362 stores each physiological parameter in the plurality of first position coordinate sets in a storage device. The processor 254 or 362 may store the determined physiological parameter values ​​in the storage device 260 or 366, and the processor 254 or 362 may temporarily store these physiological parameter values ​​in the storage device 366 and then transfer these values ​​to the external storage device 260 or 366 via the communication interface 368. Of course, the storage device 260 or 366 may be disposed in the control component 114 or 351 or externally.

[0072] Region 627 shows a relatively high radiation characteristic. The relatively high intensity may indicate a lesion, localized tissue damage, redness, inflammation, cracks, or infection. Therefore, processor 254 or processor 362 identifies region 627 as a target region for providing treatment.

[0075] The wearable physiotherapy device 100 is worn on the user's face through the fastener 202, so that the face is fully fitted with the inner layer 102 of the wearing pad 101;

[0076] The working state and function selection of the wearable physical therapy device 100 are controlled by the control component 114, or controlled by wireless control signals of the user computing device 210;

[0079] The control module 204 determines the radiation characteristics of the electromagnetic radiation received by the optical sensor 206 and activates the stimulation element 104 associated with the determined radiation characteristics.

[0080] Compared with the prior art, the wearable therapy device 100 provided in the present application sets a stimulation position 103, a detection position 107 and an installation groove 131 on the inner layer 102, so that multiple stimulation elements 104 and a first optical end point 108 can be set in the wearable pad 101, and controlled by the control component 114 to achieve multi-functional treatment plan selection; compared with traditional electrical signal transmission, the optical fiber transmission method has the advantages of fast response and high signal accuracy, and can provide feedback and adjustments in time according to the user's situation; in addition, the wearable therapy device 100 sets a fastener 202 on the outer layer 125, which makes the use process more stable, and can be applied to multiple positions and various complex environments, and has stronger adaptability.

[0081] The above is only an implementation method of the present application. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present application, but these improvements are within the scope of protection of the present application.

[0082] In this application, the term "interferometer" refers to a fiber interferometer that splits an incident light beam into a reference beam and a sensing beam. The sensing beam is affected by the parameter of interest and then interferes with the reference beam. The interferometer is configured to analyze the interference pattern generated by the interference of the affected sensing beam and the reference beam to determine the parameter of interest. Commonly used fiber interferometers include Michelson interferometer, Fabry-Perot interferometer, Sagnac interferometer, Mach-Zehnder interferometer, modal interferometer, Moiré interferometer, and white light interferometer.

[0083] In this application, a "fiber Bragg grating (FBG)" is a short section of optical fiber (a few millimeters long) that has its refractive index permanently modified to act as a mirror for specific wavelengths, thereby reflecting specific wavelengths while transmitting other mirrors. FBGs are used in sensing applications because changes in the fiber's environment, such as changes in temperature, pressure, and strain, can cause a shift in the reflected wavelength. The amount of shift from a known wavelength can be related to the temperature, pressure, and strain or changes therein in the fiber's environment.

[0084] In this application, the term "optical coherence tomography (OCT)" refers to a technique that combines optical fibers, interferometers, and computing hardware to generate cross-sectional images of the tissue being examined. OCT is similar to interferometry, with the additional step of using a computer-based algorithm to analyze the resulting interference pattern and generate a cross-sectional image of the tissue being examined. The generated cross-sectional image can then be displayed on a display device.

[0085] In this application, the phrase "fluorescence spectroscopy" refers to a technique that involves exciting known substances with incident light so that they exhibit fluorescence (wherein the known substance emits light of a different wavelength than the incident light) and receiving the emitted light to analyze the properties of the known substance. Fluorescence spectroscopy is used in conjunction with optical fibers (used as a medium to transmit the incident light and receive the emitted light) to sense changes in the environment of the known substance, such as temperature, pH, etc. The wavelength of the light emitted by the known substance can be further varied. The change in wavelength can be calibrated as a measure of environmental change when compared to a wavelength associated with a reference environment of the known substance.

[0086] In this application, the term "Brillouin scattering or Brillouin light scattering (BLS)" refers to a phenomenon in which the interaction of light with sound waves causes light to be scattered forward and backward. The backscattered light undergoes a frequency shift known as the Brillouin shift. The shift in the Brillouin signal indicates the characteristics of the sound waves as well as the physical and chemical properties of the material itself. The scattered light is analyzed using a customized spectrometer to determine the Brillouin spectrum. BLS can be combined with optical fibers and used to sense changes in the fiber environment, such as changes in temperature, pressure, etc. This causes the Brillouin shift of the fiber material to change compared to the Brillouin shift under reference environmental conditions.

[0087] In this application, "Raman scattering or Raman effect" refers to the inelastic scattering of light caused by the interaction and energy exchange between photons of light and a given molecule. The scattered light can then be analyzed to produce a Raman spectrum that indicates the chemical and physical properties of the molecule itself. The Raman effect can be combined with optical fiber to sense changes in the fiber environment, such as changes in temperature, pressure, etc., which will cause changes in the Raman spectrum of the fiber material compared to the Raman spectrum under reference environmental conditions.

[0088] In this application, the term "processor" refers to one or more of a microprocessor, a microcontroller, a general-purpose processor, a field programmable gate array (FPGA), a neural processing unit (NPU), a graphics processing unit (GPU), a tensor processing unit (TPU), an application specific integrated circuit (ASIC), etc.

[0089] In this application, "memory unit" refers to volatile memory, such as static random access memory (SRAM) and dynamic random access memory (DRAM), types of which are asynchronous DRAM, synchronous DRAM, double data rate SDRAM, Rambus DRAM, and cache DRAM).

[0090] In this application, the phrase "storage device" refers to non-volatile memory, such as EPROM, EEPROM, flash memory, etc.

[0091] In this application, the phrase "communication interface" refers to a device or module that implements a direct connection via USB, HDMI, VGA, or a wireless connection such as Bluetooth or Wi-Fi, or a local area network (LAN) or wide area network (WAN) via TCP / IP, IEEE802. GSM, CDMA, LTE or other equivalent protocols.

[0092] In this application, the term "history" in command execution refers to any instant in time earlier than the instant in time at which the command was initiated.

[0093] In this application, the term "real time" refers to the time required to measure / receive / process / transmit data as accurately as practical due to processing limitations of hardware / software / firmware.

[0094] In this application, terms such as "light", "radiation", "irradiation", "emission" and "illumination" refer to electromagnetic radiation that ranges in frequency between ultraviolet (UV) frequencies and infrared (IR) frequencies and wavelengths (including all visible light frequencies and wavelengths), where this range includes the UV and IR frequencies and wavelengths. It is important to note here that UV radiation can be classified in several ways based on their respective wavelength ranges, all of which are contemplated to be within the scope of the present invention. For example, UV radiation can be divided into Hydrogen Lyman-alpha (122-121nm), Far UV (200-122nm), Mid UV (300-200nm) and Near UV (400-300nm). UV radiation can also be divided into UVA (400-315nm), UVB (315-280nm) and UVC (280-100nm). Similarly, infrared radiation can also be divided into several categories based on their respective wavelength ranges, which are again contemplated to be within the scope of the present invention. A commonly used subdivision scheme for infrared radiation includes near infrared radiation (0.75-4 μm), short wavelength IR (1.4-3 μm), medium wavelength IR (3-8 μm), long wavelength IR (8-15 μm), and far infrared (15-1000 μm).

[0095] In this application, the term "polymer" refers to a material composed of long chains of organic molecules (8 or more organic molecules), including but not limited to carbon, nitrogen, oxygen and hydrogen as their constituent elements. The term polymer is contemplated to include naturally occurring polymers, such as wool, and synthetic polymers, such as polyethylene and nylon.

[0096] In this application, "transparent material" means a material that allows at least a portion of one or more forms of electromagnetic radiation (such as infrared, ultraviolet, X-rays, visible light, microwaves, radio waves, etc.) to pass through. Transparent materials can be transparent (allowing one or more forms of electromagnetic radiation to pass through with minimal scattering) or translucent (allowing one or more forms of electromagnetic radiation to pass through with significant diffusion or scattering). Transparent materials can be dense, such as glass, or have an open structure, such as wire mesh or woven fabric.

[0097] As used herein, a "light emitting diode (LED)" refers to a semiconductor diode capable of emitting electromagnetic radiation when supplied with an electric current. LEDs have superior power efficiency, smaller size, switching speed, physical robustness, and lifespan compared to incandescent or fluorescent lamps. In this regard, one or more LEDs may be, for example, hole-type LEDs (typically used to produce red, green, yellow, blue, and white electromagnetic radiation), surface mount technology (SMT) LEDs, bi-color LEDs, pulse width modulated RGB (red-green-blue) LEDs, and high power LEDs.

[0098] The materials used in LEDs can vary from one embodiment to another depending on the desired radiation frequency. Different frequencies can be obtained from LEDs made of pure or doped semiconductor materials. Commonly used semiconductor materials include silicon, gallium, aluminum, boron, zinc selenide, etc. Pure form or doped with elements such as aluminum and indium. For example, red and amber are produced by compositions based on aluminum indium gallium phosphide (AlGaInP), while blue, green and cyan use compositions based on indium gallium nitride. White light can be produced by mixing red, green and blue light in equal proportions, while different proportions can be used to produce a wider color gamut. White and other colored lighting can also be produced using fluorescent coatings, such as yttrium aluminum garnet (YAG) combined with blue LEDs to produce white light, and magnesium-doped potassium fluorosilicate combined with blue LEDs to produce red light. In addition, near-ultraviolet (UV) LEDs can be combined with europium-based phosphors to produce red and blue light, and copper and zinc doped zinc sulfide-based phosphors to produce green light.

[0099] In addition to conventional mineral-based LEDs, one or more LEDs may also be provided on an organic LED (OLED)-based flexible panel or an inorganic LED-based flexible panel. Such an OLED panel may be produced by depositing an organic semiconductor material on a thin film transistor (TFT)-based substrate. In addition, a discussion of OLED panels may be referenced in Bardsley, JN (2004), "International OLED Technology Roadmap", IEEE Journal of Selected Topics in Quantum Electronics, Vol. 1. An exemplary description of a flexible inorganic light-emitting diode strip may be referenced in the prior art of U.S. Patent No. US7,476,557B2, entitled "Roll-to-Roll Fabrication of Optical Sheets and Packaged Semiconductor Circuit Devices".
