DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] An exemplary embodiment of the present disclosure provides a wireless imaging device. With reference to FIGS. 1-10, a wireless imaging system is shown. The wireless imaging system may include a wireless imaging device generally designated 100. The wireless imaging system may further include a receiver (e.g., receiver 400) and a battery charging device (e.g., battery charging device 300) configured to charge a battery (e.g., battery 108). In use, the wireless imaging device ("device") 100 is a wireless device configured to provide light to an area of ​​interest and capture images and / or videos from the area of ​​interest. The device 100 may be configured for use in a variety of industries and practices, such as medical, dental, construction, automotive, aviation, or other types of industries. The device 100 may be wireless to allow for easier maneuverability and portability when using the device 100. Additionally, the wireless nature of the device 100 may reduce accidents and mistakes by eliminating wires that can be a tripping or falling hazard.

[0018] In some embodiments, the device 100 includes a scope or optical device (e.g., scope 150) coupled to a head unit (e.g., head unit 102) to aid in visualization. The device 100 may include a medical scope (e.g., endoscope, arthroscope, bronchoscope). The device 100 may be configured to work with most standard medical scopes such that the head unit of the device 100 can be coupled to most standard medical scopes without the need for additional adapters or parts. Additionally, the device 100 may be configured to allow for the use of adapters that aid in coupling the device 100 to a medical scope. The device 100 may be configured to be used for endoscopy, arthroscopy, bronchoscopy, gastroscopy, colonoscopy, cystoscopy, or other types of procedures requiring imaging. However, the device 100 may include a head unit configured to couple to a non-medical scope, such as a borescope, fiberscope, videoscope, or other types of scopes.

[0019] In some embodiments, the device 100 is a wireless medical imaging device. For example, the device 100 may be a wireless medical imaging device that allows a user to diagnose and treat a patient by viewing areas of interest within the patient. The device 100 may provide for less invasive procedures more easily because the device 100 is wireless. For example, the device 100 may be wireless such that there are no cords running from the device 100 to towers or other devices. This may result in an operating room (OR) having more usable space or a more efficient or smaller room layout since less space is taken up by towers and cables. The device 100 being wireless may result in easier maneuverability of the device 100 during use, resulting in faster and better treatment of the patient. Additionally, the device 100 being wireless may reduce the set-up, use, and take-down time for a surgical procedure. The device 100 being wireless may also reduce the number of people required to perform or assist in performing a procedure. For example, the device 100 being wireless may reduce the number of nurses or technicians required to perform a procedure. Additionally, reprocessing, cleaning, and sterilization times may also be reduced due to the lack of wires and small footprint of device 100 compared to conventional imaging systems. The improvements herein may save significant time and money for users of device 100 (e.g., healthcare providers or hospitals).

[0020] In some embodiments, the portability and wireless nature of the device 100 allows the device 100 to be used anywhere without the need for a medical environment. Because the device 100 can be used anywhere and may not require a medical environment, patients may receive medical care without traveling to another location. In some embodiments, the wireless nature of the device 100 allows it to be used in many different locations, such as in / out patient surgery centers, doctor's offices, nursing homes / long-term care facilities, and mobile clinics and surgery centers that can go directly to patients. For example, a bedridden patient in a long-term care facility who has suffered an injury can be treated and receive rehabilitation services quickly at the facility instead of spending additional time in a hospital operating room or suffering through difficult travel. The device 100 may also enable the creation of mobile diagnostic and operating rooms that can provide minimally invasive surgery next to the patient's home, thereby reducing pre- and post-operative time and quickly returning the patient to a comfortable environment. Furthermore, the compact size and easy portability of device 100 may enable the use of advanced imaging and surgical procedures in harsh environments where modern hospitals are not available, such as, for example, developing countries, military operations, or areas of natural disasters.

[0021] 1-4, device 100 may include a head unit 102 and a light source or light engine 200. Head unit 102 of device 100 may be configured to couple to a scope 150. In some embodiments, scope 150 is coupled to head unit 102 and light engine 200. In some embodiments, scope 150 is a laparoscope, an ENT scope, an arthroscope, or other type of medical imaging scope. Head unit 102 may be coupled to light engine 200 via power cable ("cable") 112. In some embodiments, head unit 102 is configured to receive an image from scope 150 that is illuminated via light from light engine 200. For example, light engine 200 may be configured to output light that passes through scope 150 to illuminate an area of ​​interest. Light from the area of ​​interest may reflect back through scope 150 toward head unit 102.

[0022] The head unit 102 may include one or more cameras and one or more image processing units configured to convert light received from the area of ​​interest into images / videos. For example, the head unit 102 may include a camera configured to receive light from the area of ​​interest via the scope 150, and the head unit 102 may include an image processing unit configured to convert the received light into image / video data. The image / video data may be transmitted to a remote receiver, which may be coupled to a display configured to convert the image / video data into one or more images / videos for viewing. In some embodiments, the device 100 includes a display screen for displaying images / videos of the area of ​​interest. For example, the device 100 may include a display screen disposed on an exterior surface (e.g., the housing 105) of the device 100 configured to display images / videos of the area of ​​interest. The user interface 116 may include a display screen configured to display images / videos of the area of ​​interest. In some embodiments, the user interface 116 is a touch screen that allows a user to control the head unit 102 and also view images / videos of the area of ​​interest. Alternatively, the device 100 may transmit the image / video data to an external display. In some embodiments, device 100 wirelessly transmits image / video data to an external display.

[0023] In some embodiments, the head unit 102 is sized and shaped to fit within a user's hand. For example, the head unit 102 may have an ergonomic design that allows the head unit 102 to easily fit in an individual user's hand for extended periods of time without causing discomfort. The head unit 102 may be configured to provide multiple gripping and holding options. In some embodiments, the head unit 102 allows the device 100 to be lightweight as compared to conventional imaging devices. For example, the head unit 102 may be between 300 grams and 500 grams, between 325 grams and 450 grams, or between 350 grams and 400 grams. For example, the head unit 102, and thus the device 100, being wireless reduces the need for additional wires and cables, thereby reducing the overall weight of the device 100, as well as eliminating the effects of wires and cables pulling on the head unit 102.

[0024] 1-4, the head unit 102 may include a housing 105. The housing 105 may comprise an exterior surface of the head unit 102. In some embodiments, the housing 105 is constructed of a durable material to allow for more rugged use of the device 100. For example, the housing 105 may be constructed of a durable polymer, metal, or a combination thereof, allowing the head unit 102 to be dropped or receive one or more impacts without damaging the head unit 102. The housing 105 may be fabricated via molding, casting, reduction processes, and / or additive processes (e.g., 3D printing). The housing 105 may include an inner cavity 118, which may be configured to receive a battery 108. The battery 108 may be a removable battery configured to be inserted into and removed from the inner cavity 118.

[0025] In some embodiments, the inner cavity 118 is configured to receive the battery 108 in a particular orientation. The inner cavity 118 may include a connection element 119 configured to couple the battery 108 to the head unit 102. In some embodiments, fully inserting the battery 108 into the inner cavity 118 couples the battery 108 to the connection element 119. When the battery 108 and the connection element 119 are coupled, the battery 108 is coupled to the head unit 102 and the battery 108 may provide power to the head unit 102. For example, inserting the battery 108 into the inner cavity 118 such that the battery 108 couples to the connection element 119 may cause the battery 108 to provide power to the head unit 102.

[0026] 1 , the battery 108 may include a proximal end 107 and a distal end 109. The distal end 109 may be opposite the proximal end 107. In some embodiments, when the battery 108 is fully inserted into the inner cavity 118, the distal end 109 may remain exposed. The exposed distal end 109 allows a user to easily grasp and remove the battery 108 from the inner cavity 118 for replacement, repair, or recharging. In some embodiments, when the battery 108 is fully inserted into the inner cavity 118, the distal end 109 is flush with the housing 105, allowing a user to comfortably grip the head unit 102 near the distal end 109 of the battery 108 while using the device 100.

[0027] In some embodiments, the head unit 102 includes a proximal end 101 and a distal end 103. The proximal end 101 can be opposite the distal end 103 and can include a power cable port 120 and a mount 115. In some embodiments, the power cable port 120 and the mount 115 are each opposite an inner cavity 118. For example, the power cable port 120 and the mount 115 can be disposed on the proximal end 101 and opposite the inner cavity 118 that is disposed on the distal end 103. The proximal end 101 can include a planar front surface. In some embodiments, the power cable port 120 and the mount 115 are disposed on the planar front surface such that the power cable port 120 is coplanar with the mount 115.

[0028] In some embodiments, the proximal end 101 is substantially planar such that the power cable port 120 is flush with the mount 115. The power cable port 120 may be coupled to the power cable 112, thereby coupling the power cable 112 to the head unit 102. The power cable port 120 may be coupled to the proximal end 113 of the power cable 112. In some embodiments, the power cable 112 is fixedly coupled to the power cable port 120. However, the power cable 112 may be removably coupled to the power cable port 120.

[0029] In some embodiments, the proximal end 101 includes a mount 115. The mount 115 may be configured to couple to a scope 150 (e.g., an endoscope). In some embodiments, the mount 115 is configured to removably couple the head unit 102 to the scope 150. The mount 115 may be configured to accommodate different types of coupling mechanisms. For example, the mount 115 may be compatible with a C-mount coupler, an ocular coupler, a direct view coupler, or other types of coupling mechanisms. In some embodiments, the mount 115 is configured to allow the head unit 102 to couple to a C-mount scope, an ocular scope, a direct view scope, or other types of scopes. The mount 115 may be configured to couple and secure the scope 150 to the head unit 102. The mount 115 allows the head unit 102 to be plug-and-play compatible with various types of scopes, such as the scope 150. For example, during use of the device 100, a user may couple a first scope to the head unit 102 (e.g., via the mount 115) and then easily detach the first scope from the head unit 102 and couple a second scope to the head unit 102. In some embodiments, the scope 150 includes an adjustment mechanism 114, and the scope 150 is coupled to the mount 115 via the adjustment mechanism 114. The adjustment mechanism 114 may help secure the scope 150 to the head unit 102 in the mount 115. In some embodiments, the adjustment mechanism 114 allows the scope 150 to be freely rotated relative to the head unit 102 without removing the scope 150 from the mount 115. In some embodiments, the scope 150 is configured to rotate 360 ​​degrees relative to the head unit 102 and / or the mount 115, allowing a user to achieve a desired orientation and field of view.

[0030] In some embodiments, the scope 150 includes the adjustment mechanism 114 such that the scope 150 is coupled to the mount 115 via the adjustment mechanism 114. Alternatively, the head unit 102 can include the adjustment mechanism 114 coupled to the mount 115, and the scope 150 can be coupled to the adjustment mechanism 114 to secure the scope 150 to the mount 115 and the head unit 102.

[0031] In some embodiments, adjustment mechanism 114 is configured to allow a user to adjust and / or control various functions of device 100. For example, adjustment mechanism 114 may allow a user to adjust the focus and / or zoom (e.g., zoom in and out) of images / video received by head unit 102 from scope 150. Adjustment mechanism 114 may also allow a user to adjust the amount of light illuminated by scope 150 onto an area of ​​interest. In some embodiments, while using device 100, a user may hold head unit 102 in one hand and adjust adjustment mechanism 114 with the same hand. Alternatively, the user may use the other hand to adjust adjustment mechanism 114.

[0032] 1-2, the proximal end 101 may include a protrusion 110. The protrusion 110 may be configured to prevent a user's hand from slipping towards the scope 150. In some embodiments, the protrusion 110 provides an ergonomic resting position for the user's hand or a portion of the user's hand. The protrusion 110 may include one or more antennas. The one or more antennas may be configured to transmit data (e.g., image / video data, command and control signals, etc.) to a remote receiver and receive information from a remote device. In some embodiments, the one or more antennas are located anywhere within the head unit 102, such as proximate to the proximal end 101, proximate to the distal end 103, and / or between the proximal end 101 and the distal end 103.

[0033] In some embodiments, the one or more antennas are configured to wirelessly communicate with a remote receiver (e.g., receiver 400). For example, head unit 102 may include one or more antennas, and head unit 102 may be configured to wirelessly communicate with a remote receiver via a wireless modality. The wireless modality may be ultra-wideband (UWB), Bluetooth, near field communication (NFC), Wi-Fi, cellular, or other types of wireless modalities. In some embodiments, device 100 utilizes UWB to communicate with a remote receiver (e.g., receiver 400). Device 100 may further include built-in encryption to securely transmit data to the remote receiver. For example, device 100 may associate image / video data generated by head unit 102 with an authentication factor, such as an authentication token. Device 100 may transmit image / video data along with the authentication factor to a remote receiver (e.g., receiver 400). The remote receiver may include a cryptographic engine configured to authenticate an authentication factor received along with the image / video data to ensure that the image / video data was securely transmitted from the head unit 102. Additionally, associating the image / video data generated by the head unit 102 with the authentication factor prevents unauthorized users and / or devices from accessing the image / video data.

[0034] In some embodiments, during use of the device 100, other devices, such as other wireless devices, are used simultaneously adjacent to the device 100, causing interference. The device 100 utilizing UWB for wireless communication prevents or minimizes interference from other devices while maintaining the ability to transmit large data packets (e.g., image / video data). For example, by utilizing UWB communication, the device 100 can transmit large size image / video data, including high resolution images / videos, as well as command and control signals, to a remote receiver (e.g., receiver 400) for viewing via a display coupled to the receiver. In some embodiments, the wireless communication between the device 100 and the remote receiver is configured to act as a cable for encoding purposes. This allows for simplified communication protocols and debugging of problems during use of the device 100. In some embodiments, the device 100 is configured to provide low latency communication such that the lag between the head unit 102 receiving data from the area of ​​interest viewed by the scope 150 and it being received by the receiver and displayed to the user via the display screen is minimized. A device 100 that provides low latency communications may increase the efficiency of a procedure during which the device 100 is in use, in addition to reducing the risk of injury, error, or accidents during a procedure using the device 100 .

[0035] In some embodiments, the distal end 103 is configured to receive the battery 108 via the inner cavity 118. In some embodiments, the head unit 102 is coupled to the battery 108, allowing the device 100 to be wireless without the need for a power line. The battery 108 may be rechargeable. In some embodiments, the battery 108 is configured to be removably coupled to the head unit 102 so that the battery 108 can be quickly replaced and replaced with a fully charged battery 108. In some embodiments, when the battery 108 is received within the inner cavity 118 of the head unit 102, all or a portion (e.g., a distal portion) of the distal end 109 may be exposed (e.g., a portion of the distal end 109 that is not disposed within the inner cavity 118 is flush with the housing 105). The head unit 102 may include a locking device 117 to secure the battery 108 in place when the battery 108 is coupled to the head unit 102. The locking device 117 may be configured to allow the battery 108 to be removably coupled to the head unit 102. For example, the locking device 117 may be configured to engage a portion of the battery 108 to secure the battery 108 within the inner cavity 118. A user may manipulate the locking device 117, such as by disengaging the locking device 117, to allow removal of the battery 108 from the inner cavity 118. In some embodiments, the locking device 117 allows the battery 108 to be quickly replaced and reset in approximately 30 seconds. The battery 108 and locking device 117 reduce downtime when replacing the battery 108 during use of the device 100.

[0036] With reference to FIG. 4 , replacing the battery 108 in the head unit 102 resets the device 100 to a basic state. For example, when the battery 108 is fully placed in the inner cavity 118, the battery 108 may engage the connection element 119. When the battery 108 is at least partially removed from the inner cavity 118, the battery 108 may no longer engage the connection element 119, thereby resetting the device 100 and / or entering the basic state. Resetting the device 100 to the basic state may be useful for correcting errors or problems that have occurred during use of the device 100. In resetting the device 100 to the basic state, all or most of the settings of the device 100 may be reset to address errors or problems that previously occurred. Additionally, resetting the device 100 ensures that no protected data, such as patient data or HIPAA data, is stored locally and allows for a quick start-up cycle.

[0037] In some embodiments, the device 100 includes an internal battery disposed within the head unit 102. The internal battery may provide power to the device 100 when the battery 108 is disengaged from the connecting element 119 and / or removed from the inner cavity 118. The internal battery providing power to the device 100 may prevent the device 100 from resetting or going to a base state when the battery 108 is replaced or removed. This allows for continued use of the device 100 even when the battery 108 is being replaced or removed. In some embodiments, the device 100 is configured to allow a user to disengage the internal battery so that the internal battery does not provide power to the device 100 during replacement and / or removal of the battery 108. Disengaging the internal battery allows a user to reset the device 100 to a base state when the battery 108 is disengaged from the connecting element 119 and / or removed from the inner cavity 118.

[0038] In some embodiments, the battery 108 is configured to provide at least 1 hour of continuous operation time for the device 100. For example, during a single use of the battery 108, at least 1 hour, 2 hours, 3 hours, 4 hours, 5 hours, or more than 6 hours of operation time for the device 100 is obtained. In some embodiments, the battery 108 is configured to provide 30 minutes to 600 minutes, 180 minutes to 540 minutes, or 240 minutes to 480 minutes of operation time. The battery 108 may be configured to allow the device 100 to operate without battery change / replacement for a period of time longer than most surgeries or procedures require. This is due to the power and efficiency of the battery 108, as well as the highly efficient electronics of the device 100 designed to ensure the life of the battery 108 and the use of the device 100. Additionally, the device 100 may be configured to operate with lower power consumption than conventional imaging devices. For example, the device 100 may operate with less energy compared to conventional imaging devices. In some embodiments, the device 100 uses 1% to 5% of the total power required by conventional imaging devices. The wireless imaging device system, including device 100, receiver 400, and battery charging device 300, uses 1% to 5% of the total power required by a conventional imaging device. This results in less power usage and less expense for the user of device 100 (e.g., a healthcare provider or hospital). Additionally, because device 100 is wireless and portable, device 100 has a smaller footprint compared to conventional imaging devices. The smaller footprint of device 100 makes device 100 easier to clean and sterilize compared to conventional imaging devices.

[0039] In some embodiments, the reduced power usage of our wireless imaging device system (device 100, receiver 400, and battery charging device 300) also reduces the amount of waste heat generated compared to conventional imaging systems. The waste heat must be removed from the OR, leading to improved power savings. A wireless imaging device system (device 100, receiver 400, and battery charging device 300) that reduces the amount of waste heat results in a more efficient imaging system due to reduced power usage (heating, ventilation, and air conditioning).

[0040] 1 and 5, the head unit 102 may be coupled to the light engine 200 via the power cable 112. The light engine 200 may include a first end 201 and a second end 203. The first end 201 may be disposed opposite the second end 203. In some embodiments, the light engine 200 is coupled to the power cable 112 at the first end 201 and coupled to the scope 150 at the second end 203. The first end 201 and the second end 203 may be disposed along a central axis AA. In some embodiments, the central axis AA bisects the light engine 200. For example, the light engine 200 may be symmetrical about the central axis AA.

[0041] The power cable 112 may include a proximal end 113 and a distal end 111. In some embodiments, the proximal end 113 is coupled to the head unit 102 at a power cable port 120. The distal end 111 may be coupled to the light engine 200. The power cable 112 may be configured to provide power to the light engine 200. In some embodiments, the power cable 112 is flexible to allow the light engine 200 to rotate relative to the head unit 102. For example, the flexibility of the power cable 112 allows the light engine 200 to rotate 360 ​​degrees relative to the head unit 102. In some embodiments, the power cable 112 is configured to be flexible so as not to impede the rotation of the light engine 200 relative to the head unit 102. The light engine 200 may be configured to generate light to illuminate a target area. The light engine 200 may output light that travels through the scope 150 to the target area.

[0042] The light engine 200 may be configured to generate and output light. The light engine 200 may include an outer shell 202. The outer shell 202 may be constructed of aluminum, other metals, or polymers with high thermal conductivity. In some embodiments, the outer shell 202 acts as a heat sink to dissipate heat generated by the light engine 200. For example, the outer shell 202 may dissipate heat generated by the light engine 200 such that the light engine 200 remains below a temperature that may cause burns, such as below about 43.5°C. However, the outer shell 202 may be configured to dissipate heat generated by the light engine 200 such that the light engine 200 remains below about 45°C, about 40°C, about 35°C, about 30°C, or about 25°C. In some embodiments, the light engine 200 is configured to remain below about 45°C (e.g., below 43.5°C) during extended use of the device 100 (e.g., more than 4 hours of use). Keeping the light engine 200, and therefore the device 100, below approximately 40° C. prevents the device 100 from becoming a fire hazard, as well as preventing burns to individuals around the device 100.

[0043] In some embodiments, the light engine 200 includes an illumination source 204. The illumination source 204 may be a laser, a light emitting diode (LED), an incandescent light source, or any other type of light source capable of providing illumination.

[0045] The illumination source 204 may be configured to generate and output the light 210. The illumination source 204 may output the light 210 having a peak wavelength between 440 nm and 470 nm. In some embodiments, the light 210 is unconditioned light output by the illumination source 204. The light engine 200 may include an optical element 212 configured to condition, collimate, filter, direct, and / or focus the light 210 output by the illumination source 204. In some embodiments, the optical element 212 includes one or more homogenizing rods configured to collimate and direct the light 210. The optical element 212 may be constructed of glass, plastic, or other types of materials such that the optical element 212 can condition, collimate, filter, direct, and / or focus the light 210.

Converter 214 may be disposed within shell 202 of light engine 200 and configured to convert light 210 to light 218. In some embodiments, light 218 has a different wavelength than light 210.

[0046] In some embodiments, the light converter or converter 214 is configured to convert the incident light 210 to the light 218 output by the light engine 200. The light 218 can be white light between 480 nm and 770 nm. In some embodiments, the converter 214 is a volumetric spectral converter including phosphor particles. The converter 214 can include phosphor particles volumetrically disposed within a substrate. In some embodiments, the substrate can be a homogenous composite substrate of a non-converting material (e.g., plastic, acrylic, glass, ceramic). The phosphor particles volumetrically disposed within the converter 214 can allow the converter 214 to more efficiently convert the light 210 to the light 218. In some embodiments, the converter 214 is comprised of multiple layers, each layer can have multiple phosphor particles volumetrically disposed therein. The multiple layers can form a volumetric spectral converter. In some embodiments, the multiple layers are disposed such that each layer is substantially perpendicular to the light 210. In some embodiments, light 210 is incident on converter 214 at an angle between 45 degrees and 135 degrees, between 65 degrees and 125 degrees, or between 75 degrees and 115 degrees.

[0047] The converter 214 may be selected to convert light from the illumination source 204 to another wavelength of light, e.g., narrow or broad spectrum, or incoherent light. The converter 214 may be comprised of a conversion material, including, for example, phosphorescent materials, fluorescent materials, other radiation conversion materials, or combinations of these materials. The conversion material is volumetrically disposed on a substrate, which may include, for example, PMMA, polystyrene, polycarbonate, polyester, copolymers, or mixtures of combinations of the aforementioned materials, to create an effectively homogenous composite. This process may include, for example, extrusion, coating, lamination, compounding, mixing, or suspension. In some embodiments, the converter 214 has a thickness of 0.1 mm to 5 mm and a radius of 0.1 mm to 5 mm.

[0048] In some embodiments, the converter 214 is a volumetric phosphor disk configured to convert the light 210 to light 218. Alternatively, the converter 214 may be a volumetric phosphor sphere, a cube, a rectangular prism, a pyramid, a sphere, or any other shape desired. The converter 214 may be fixed within the light engine 200. For example, the converter 214 may be disposed between the optical element 212 and a window 219 of the light engine 200. In some embodiments, the converter 214 is a disk fixed between the optical element 212 and the window 219 via friction, glue, epoxy, fasteners, or other methods of fixing the converter 214 between the optical element 212 and the window 219. The light 218 may exit the converter 214 such that the light 218 passes through the window 219 and exits the light engine 200. The window 219 may be transparent to allow the light 218 to pass through.

[0049] In some embodiments, the outer shell 202 includes an opening 213 extending at least partially through the outer shell 202. The opening 213 may be in optical communication with the window 219 such that the light 218 from the converter 214 passes through the window 219 and exits the light engine 200 through the opening 213. In some embodiments, the opening 213 extends through the outer shell 202 along the central axis AA. In some embodiments, the illumination source 204, the optical element 212, and the window 219 are side-by-side. For example, the illumination source 204, the optical element 212, the window 219, the converter 214, and the opening 213 may be disposed along the central axis AA of the light engine 200. In some embodiments, the illumination source 204, the optical element 212, the window 219, the converter 214, and the opening 213 are disposed in series along the central axis AA.

[0050] 2 and 5, the light engine 200 may include a ring 216. The ring 216 may be configured to aid in coupling the light engine 200 to the scope 150. For example, the scope 150 may include a coupling element 122 that may be received by the light engine 200 and secured to the light engine 200 via the ring 216. In some embodiments, the scope 150 includes a coupling element 122 that is received by the ring 216 of the light engine 200 such that the coupling element 122 and the scope 150 are secured to the light engine 200. The light engine 200 may be secured to the scope 150 via the coupling element 122 and the scope 150 such that the light engine 200 and the scope 150 are rotatable relative to the head unit 102. For example, the light engine 200 and the scope 150 may rotate 360 ​​degrees relative to the head unit 102.

[0051] 6A and 6B, the battery 108 is rechargeable and may be recharged using a battery charging apparatus 300.

[0059] In some embodiments, receiver 400 is configured to receive image / video data in real-time with low latency and configured to cause display device 600 to display the images / video so that a user can view the illuminated target area in real-time with low latency. Display device 600 may be configured to generate display 700. Display 700 may be color (FIG. 8), black and white (FIGS. 9A and 9B), or grayscale.

[0060] In some embodiments, the receiver 400 causes the display device 600 to display and generate the display 700. For example, the receiver 400 may receive image / video data from the head unit 102 and transmit the image / video data to the display device 600 to display an image / video related to the image / video data. The display 700 may be configured to display an image 706, which may be an image received by the scope 150, processed by the head unit 102, and transmitted to the receiver 400. For example, the image 706 may be an image of an area of ​​interest that the scope 150 is looking at. In some embodiments, the display 700 is configured to generate and display an image or video. The display 700 may include a power indicator 702 that indicates a power level of the battery 108.

[0061] In some embodiments, the display 700 includes a brightness indicator 708. The brightness indicator 708 may indicate a brightness level of the image 706. In some embodiments, the brightness indicator 708 indicates the lux of the light 218 from the light engine 200. For example, a user may use the user interface 116 to adjust the lux of the light engine 200, thereby controlling the brightness of the light 218, resulting in the image 706 becoming brighter or dimmer. An increase in brightness may be indicated via the brightness indicator 708.

[0062] The display 700 may include a function indicator 710. In some embodiments, the function indicator 710 is a white balance function indicator to indicate activation of a white balance function. For example, the display 700 may have a low brightness level, resulting in the image 706 being dim or having a low brightness, making it difficult to see features of the area of ​​interest viewed by the scope 150. In some embodiments, the user interface 116 is used to increase the brightness of the display 700. For example, a user may use the user interface 116 to increase the brightness of the display 700, resulting in the brightness indicator 708 indicating an increase in the brightness level of the image 706. In some embodiments, the brightness indicator 708 may indicate a change in sensitivity to an image sensor or video sensor located within the head unit 102. This may indicate how bright the image output by the head unit 102 is. For example, a user may use the user interface 116 to increase the brightness of the image 706, resulting in a change in the sensitivity of the image sensor or video sensor of the head unit 102. As the brightness of the image 706 increases, the brightness indicator 708 changes.

[0063] Additionally, display 700 may have colors displayed inaccurately, making it difficult to see features of the area of ​​interest viewed by scope 150. Function indicator 710 may indicate that a white balance function has been applied to image 706, such that white objects in image 706 appear brighter or with more accurate colors to assist a user in seeing features of image 706.

[0064] In some embodiments, the display 700 is configured to digitally zoom the image 706. For example, a user may use the user interface 116 to zoom in and out of the image 706 via the display 700. In some embodiments, the display 700 is configured to automatically zoom in or out based on the content of the image 706. A user may digitally zoom in and out of the image 706 using the user interface 116 or the display 700.

The mounting bracket 500 may be configured to allow the receiver 400 to be coupled to a display (e.g., a display device 600) such that the receiver 400 is fixed to the display device. For example, the mounting bracket 500 may be coupled to a bottom portion 404 of the receiver 400, and the mounting bracket 500 may be further coupled to the display device 600 to couple the receiver 400 to the display device 600. The mounting bracket 500 may include one or more arms 504 and a coupling mechanism 502. The coupling mechanism 502 may be configured to couple to the receiver 400 (e.g., the bottom portion 404 of the receiver 400). The arm 504 may be configured to assist the mounting bracket 500 in coupling to the display device 600. In some embodiments, the receiver 400 is coupled and fixed to the display device 600 by coupling the arm 504 to the display and coupling the coupling mechanism 502 to the receiver 400. In some embodiments, the mounting bracket 400 has two arms 504. However, the mounting bracket 500 may have one arm, three arms, four arms, or more than four arms. In some embodiments, the connecting arm 504 is intended to interface with a VESA mount, or other mounting standard, on the back of the display device 600.

[0066] In some embodiments, the mounting bracket 500 is configured to couple to the receiver 400 and to the back of the display device 600 such that the receiver 400 is disposed above the display device 600. By coupling the receiver 400 to the display device 600 such that the receiver 400 is disposed above the display device 600, the receiver 400 and the display have an overall smaller footprint and a less bulky configuration. Additionally, by disposing the receiver 400 above the display device 600, the amount of clutter and loose cords is reduced. In some embodiments, the display device 600 is a portable display that allows the receiver 400 and device 100 to be used anywhere.
