[0029] This disclosure describes a cosmetic applicator system that minimizes, modifies, attenuates, changes, reduces, compensates for, or similarly mitigates involuntary movements by stabilizing, guiding, operating, controlling, etc., an applicator for a user and is also designed to be flexible enough to accommodate different types of commercially available cosmetic applications. This disclosure further describes a system and features for enhancing the functionality of such a cosmetic applicator system.

[0030] The basic features and operation of a motion stabilization device for a cosmetic applicator are described in US patent no. 11,458,062.

[0031] Figure 1 shows a conventional motion stabilization device 1100, which serves as a base unit for receiving a cosmetic applicator according to one embodiment. The device 1100 comprises a handle portion 1101, a receiver portion 1102, and a strap 1103. The receiver portion 1102 includes an interface 1104, shown as a male connector that couples with a cosmetic applicator, which will be discussed in detail below. The receiver portion can be used for communication between the base unit and the applicator. The connection to an adapter and / or an applicator can be achieved using a mechanical coupling, such as a screw or snap-on fitting, or by means of magnets.

[0032] Figure 2 shows how device 1100 is coupled with adapter 1105 and a makeup applicator 1106. It can be seen that the adapter fits onto the exposed end of the receiving portion 1102. The adapter has electrical coupling connectors (a female connector - not shown) in a recessed portion to make contact with the electrical interface of the receiving portion 1101.

[0033] As shown in [Fig. 2], the receiving portion 1102 is configured to contort, articulate, reposition, etc., between an upright posture (as shown in [Fig. 1]) and an inclined posture (as shown in [Fig. 2]). This is achieved using a hinge mechanism contained within the receiving portion 1102. [Fig. 2] shows that the hinge mechanism is a self-leveling / motion-stabilizing hinge.

[0034] Fig. 3A shows a diagram of the internal components of the device 1100 according to one embodiment. In the handle portion, the device includes a power supply 1301, which may be a battery or similar. The device includes a printed circuit board (PCB) assembly 1302, which may include the position sensor circuit 1307, the reader circuit 1308, the control circuit 1309 and the communication interface 1310, as included in art.

[0035] For example, like the sensor circuit 1307, the PCBA may include at least one inertial sensor and at least one distributed motion sensor to detect involuntary muscle movements and measure the signals associated with these involuntary muscle movements that are created when a user negatively affects the applicator's movement. These sensors also detect the movement of the stabilized output relative to the device. The control circuits send voltage commands to the motion-generating elements (described below) in response to the signals to cancel out the user's involuntary tremors or muscle movements. This cancellation maintains and stabilizes the applicator's position, keeping it stable.

[0036] Those skilled in the art will readily appreciate that a system and method according to the present invention can utilize various implementations of the control circuits and sensor circuits that would be within the spirit and scope of the present invention. In one embodiment, the control circuit 1309 includes an electrical system capable of producing an electrical response from sensor inputs such as a programmable microcontroller or a user-programmable pre-diffused array (FPGA). In one embodiment, the control circuit includes an 8-bit ATMEGA8A programmable microcontroller manufactured by Atmel because of its low overall cost, low power consumption, and suitability for use in high-volume applications.

[0037] In one embodiment, at least one inertial sensor in the sensor circuit is a sensor comprising, in particular, an accelerometer, a gyroscope, or a combination of both. In another embodiment, at least one distributed motion sensor in the sensor circuit is a non-contact position sensor comprising, in particular, a Hall effect magnetic sensor.

[0038] The system created by combining the sensor circuit, the control circuit, and the motion-generating elements can be a closed-loop control system that detects movement and acceleration at various points in the system and transmits detailed information to a control algorithm that moves the motion-generating elements appropriately to cancel the net effect of involuntary muscle movements of a user and thus stabilize the position of the applicator. The operation and details of the control system elements and the control algorithm are included in the art, as described in US PG Publication 2014 / 0052275A1.

[0039] The communication interface 1310 may include a network controller such as BCM43342 Wi-Fi, frequency modulation and a Bluetooth combo chip Broadcom, for the interface with a network.

[0040] In the receiving portion of the device, there may be two motor elements to allow three-dimensional movement of the receiver as an anti-shake function. The two motor elements comprise a y-axis motor element 1303 and an x-axis motor element 1304, each connected to and controlled by the PCB A 1302. Each of the motor elements may be servomotors as defined in the article. The device further includes a terminal effector coupling 1305, which is configured to be coupled with the adapter 1105. The terminal effector coupling 1305 may include a radio frequency identification (RFID) reader 1306, configured to read an RFID tag, which may be included with the applicator, as shown below.

[0041] Figure 3B shows a diagram of an alternative embodiment of the device 1100 in which the receiving portion comprises an electromagnetic positioner 1311 instead of the driving elements shown in Figure 3A. The electromagnetic positioner 1311 may comprise U-shaped magnetic cores 1312 arranged around a non-magnetic tube 1313, filled with a magnetic fluid 1314. Each of the magnetic cores comprises arm portions surrounded by windings 1315. The magnetic cores can be controlled by the control circuit of the PCBA 1302 to act as a controllable active magnetic field generating structure, which is used to generate a variable magnetic field that acts on the magnetic fluid, causing it to move, thus allowing the armature to be moved to the desired position and / or coordinate orientation.Details of the implementation of the 1311 electromagnetic positioner can be found in U.S. patent no. 6553,161.

[0042] In the conventional motion stabilization device described above, there is a problem, namely that the interface 1104 which receives the adapter 1105 requires a specific fixing point to align correctly with the interface.

[0043] Therefore, the embodiments below provide a universal adapter connection between the handle of the motion stabilization device in order to improve the user experience and reduce the difficulty and time required to set up the system for use.

[0044] In one embodiment, this disclosure relates to a cosmetic applicator. The cosmetic applicator can be used for a variety of cosmetic applications, including, but not limited to, mascara, eyeliner, eyebrow products, lip products (lipstick, lip gloss, lip pencil, etc.), skin and / or hair products. In one embodiment, the cosmetic applicator may include an adapter, the adapter being able to connect the cosmetic applicator to a motion stabilizer. A motion stabilizer can be, for example, a handle that can counteract involuntary movements such as tremors or spasms. These movements can interfere with the application of cosmetic products and can also make general interaction with cosmetic applicators or tools difficult. For example, many cosmetic products require movement or twisting force to open or extrude the product. It can be difficult for users to achieve the necessary range of motion or precision to apply these forces to the cosmetic. In one embodiment, the cosmetic applicator can hold a cosmetic and can allow the appropriate force to be applied to the cosmetic to open, close, mix, stir, agitate, extrude, or achieve other similar functions necessary for application.

[0045] Figure 4 shows an overview of a cosmetic attachment device including a motion stabilizer device 150 and a cosmetic adapter 100, according to an embodiment of this disclosure. The motion stabilizer device 150 may include at least one of a handle portion 151 and a hinge portion 152 (receiving portion). In one embodiment, the handle portion 151 is functionally similar to the handle portion 1101 shown in Figure 1. In another embodiment, the receiving portion 152 is functionally similar to the receiving portion 1102 shown in Figure 1. The motion stabilizer device 150 as a whole is referred to as the motion stabilizer handle.In one embodiment, the cosmetic attachment device includes a cosmetic adapter 100, wherein the adapter 100 is coupled to the receiving portion 152 of the motion stabilizer device 150. The cosmetic adapter 100 is configured to hold a tool or a cosmetic product. In one embodiment, the cosmetic adapter 100 includes a universal adapter configured to hold different types of cosmetic products. For example, the adapter 100 may include a ring-shaped cosmetic holder. Different configurations of the adapter 100 can be used for different cosmetic products and tools. For example, the shape and dimensions of the cosmetic holder can be configured for different cosmetic products. The adapter 100 can be easily attached to and removed from the motion stabilizer device. The basic features and operation of the cosmetic attachment device of [Fig.4] are described in pending US patent applications 18 / 091,882; 18 / 091,920; 18 / 091,843; 18 / 091,925; 18 / 148,957; and 18 / 148,880; and 18 / 148,930. .

[0046] In one embodiment, the adapter 100 is coupled to the receiving portion 152 of the motion stabilizer device 150 via a magnetic attachment. The base or lower end of the adapter 100 forms a chamber that can be inserted onto a projection at the tip of the receiving portion 152. The base of the adapter has at minus one magnet, the at least one magnet being attracted to and attached to a magnet in the receiving portion 152. In one embodiment, the chamber formed at the base of the adapter 100 can fit onto the receiving portion 152 in more than one orientation. The chamber can be a hollow area within the body of the adapter that is entirely contained by the walls of the adapter 110. The chamber can be approximately conical in shape. In one embodiment, the chamber is cylindrical. The chamber can be configured to fit onto a protrusion on one end of the motion stabilizer. The chamber can be used to align and guide the attachment of the cosmetic applicator onto the motion stabilizer. Fitting the chamber onto and around the protrusion on the end of the motion stabilizer limits lateral movement that would misalign the cosmetic applicator and the motion stabilizer.It may be easier for a user to align the chamber with the end of the motion stabilizer than for the user to align the edges of the circular face of the adapter with the edges of the circular face of the motion stabilizer. The chamber may have rotational symmetry so that the cutout can be placed on the end of the motion stabilizer in any orientation or at any degree of rotation around the axis of the chamber. In one embodiment, the lower end of the adapter body may include additional physical structures that can align, guide, and secure the adapter to the motion stabilizer.

[0047] In one embodiment, one or more motion stabilization components are placed in an inner sleeve, the inner sleeve being able to be inserted into the motion stabilizing device 150. In one embodiment, the motion stabilizing device 150 may be a hollow shell (for example, a cylindrical shell), and the inner sleeve containing motion stabilization components may be a cylindrical sleeve with a diameter that is smaller than the diameter of the motion stabilizing device 150. The motion stabilization components may be located in the inner sleeve and may be aligned with the positions illustrated in [Fig. 3A] and [Fig. 3B].

[0048] In one embodiment, the inner sleeve can form a receptacle for one or more motion stabilization components. For example, the inner sleeve can have cutouts along its length, the cutouts being sized for one or more motion stabilization components. Each motion stabilization component can be placed or integrated into a cutout to be secured in the inner sleeve. In one embodiment, the inner sleeve can be a hollow cylinder, in which motion stabilization components are placed inside the hollow cylinder. The inner sleeve can allow the motion stabilization components to be placed in the motion stabilizing device and the removal of the motion stabilizing components from the motion stabilizing device if necessary. In one embodiment, the cosmetic fastening device may include a locking mechanism and / or an ejection mechanism to secure and release the inner sleeve and the motion stabilizing components contained therein.

[0049] In one embodiment, the motion stabilizer device 150 may include a strap adjustment system 405 disposed at one end of the handle portion 151. Many disabled users may have difficulty using both hands, as well as performing a pinching or similar movement. Therefore, it may be difficult to adjust the strap 1103 with a simple one-handed pulling or pushing motion. Thus, the strap adjustment system 405 can be configured to adjust a strap 1103 around one of the user's hands without requiring fine manipulation and dexterity.The strap 1103 can be attached or fixed to the motion stabilizer device 150 at one end of the strap 1103, and the strap adjustment system 405 can receive a second end of the strap 1103 through one or more openings and adjust the amount of the strap 1103 pulled or pushed through the one or more openings. By doing so, the size of a loop formed between the motion stabilizer device 150 and the strap 1103 can be adjusted to be narrower or wider by the strap adjustment system.

[0050] The first end of the strap 1103 can be attached or fixed, for example, to the handle portion 151 or to the receiver portion 152. The attachment point of the first end of the strap 1103 can be modified according to the shape or structure of the motion stabilizer device 150 to accommodate the width of most user hands for a single attachment point. Alternatively, the attachment point of the first end of the strap 1103 can be dynamic or adjustable to allow for further customization according to the user's hand width. The user's hand width can be defined as, for example, a distance measured across the palm of the user's hand in a direction perpendicular to a longitudinal axis of the arm.That is to say, the width of the hand can be measured from a little finger to an index finger along the outermost edges of said fingers. When gripping the motion stabilizer device 150, the strap 1103 can be positioned along the back of the user's hand (on the side opposite the palm). In most cases, the user can position their thumb outside the loop to wrap it around the handle portion 151, but cases where the user positions their thumb inside the loop may also occur. Other cases may occur when, for example, the user does not have a thumb or other missing fingers. fingers, and that the 1103 strap can be adjusted accordingly for a better fit without dexterity-intensive manipulations

[0051] Figure 5 illustrates a strap adjustment system 405a with friction locks, according to an embodiment of this disclosure. In one embodiment, the strap adjustment system 405a includes a locking spring 410, a housing cap 415, and a roller wheel 420. The strap 1103 passes through a first opening and a second opening formed between the handle portion 151 and the housing cap 415. The locking spring 410 and the roller wheel 420 are disposed between the first and second openings in a chamber of the strap adjustment system 405a. The locking spring 410 is attached to a first side of the chamber proximal to the handle portion 151, and the roller wheel 420 is attached to a second side of the chamber proximal to the housing cap 415. The roller wheel 420 has an axle around which the roller wheel 420 rotates.The axle can be fixed to one or both ends of the housing cap 415. For example, a first axle end and a second axle end are disposed in a first axle housing and a second axle housing formed as part of the second side of the chamber, the first axle housing and the second axle housing each comprising an elongated opening extending in the first and second directions through which the first axle end and the second axle end can move between the engaged and disengaged states of the roller wheel 420. The axle, and therefore the roller wheel 420, is configured to move in a direction towards or away from the locking spring 410 (up-down direction).The roller wheel 420 is configured to come into contact with the strap 1103 along one side of the strap 1103, the first side being opposite a second side of the strap 1103 configured to come into contact with the locking spring 410.

[0052] As shown in [Fig. 5] on the left, the locking spring 410 applies a force (downward force) against the second side of the strap 1103 towards the housing cap 415 and the roller wheel 420, causing the strap 1103 to deform along a portion of the strap 1103 located inside the chamber. For example, the locking spring 410 can be driven towards the strap 1103 by means of a stored spring force or a magnetic force. For example, the locking spring 410 is a magnet driven towards the strap 1103 by means of a magnetic force (for example, the magnetic force is generated by means of a magnetized pole of the same polarity located proximal to the magnetized pole of the locking spring 410 driving the locking spring 410 towards the strap 1103).

[0053] In one embodiment, the strap 1103, when deformed and pushed downwards towards the housing cap 415, butts against a first locking edge 415a of the housing cap 415 at a first location of the strap 1103 and a second locking edge 415b of the housing cap at a second location of the strap 1103. The stop of the strap 1103 at the first locking edge 415a and the second locking edge 415b creates a frictional force sufficient to prevent translation of the strap 1103 (movement to the left or to the right). The first locking edge 415a and the second locking edge 415b are formed as part of the housing cap 415 and as part of the first and second openings. Although shown smooth, the first and / or second side of the strap 1103 may include striations, bumps, serrations, hollows, etc.or other friction features to provide additional resistance to translation when the strap 1103 abuts against the first locking edge 415a and the second locking edge 415b. The same or additional friction features may be formed on a surface of the locking spring 410 to further resist the translation of the strap 1103. The same or additional features may be formed on a surface of the roller wheel 420 to assist the translation of the strap 1103 via the roller wheel 420. In addition, it may be desirable for only one of the first locking edge 415a or the second locking edge 415b to be configured to prevent the strap 1103 from translating. It may be advantageous to use additional locking edges to prevent the translation of the strap 1103.

[0054] In one embodiment, to the right of [Fig. 5], the roller wheel 420 can be pushed upwards towards the handle portion 141 to engage the strap 1103, straighten the strap 1103, and depress the locking spring 410. In one embodiment, the upward movement reduces friction between the strap 1103 and the first locking edge 415 and the second locking edge 415b to allow the strap 1103 to move to the left or right. This movement is achieved by rolling the roller wheel to the left or right while simultaneously forcing the roller wheel 420 upwards.For example, the user can grasp the motion stabilizer 150 along the handle portion 151, place the roller wheel 420 on a flat surface, such as a table, and apply force toward the flat surface while sliding the motion stabilizer 150 in the left or right direction. Of course, left and right directions are described, but other opposite directions can be used. For example, the user can be seated and place the roller wheel 420 on one of their legs, then push or pull it toward their body. For example, the user can place the roller wheel 420 on a vertical surface, then move the motion stabilizer 150 up or down.

[0055] In one embodiment, the roller wheel 420 is configured to rotate about an axis of the motion stabilizer device 150 (the up-down axis as illustrated) so that any movement by the user will move the strap 1103 to tighten or loosen it around the user's hand. For example, the roller wheel 420 can be mounted on a swiveling platform formed as part of the housing cap 415. This can be particularly useful when the user has a limited range of motion and can only move the motion stabilizer device 150 in a predetermined direction that is not parallel to the translational direction of the strap 1103.Therefore, the roller wheel 420 is configured to pivot and then roll along the user's axis of movement, and the roller wheel 420 is coupled to one or more additional roller wheels, gears, and screws to convert the rolling motion of the roller wheel 420 into translation of the strap 1103.

[0056] As described above, moving the strap 1103 leftward or rightward via the roller wheel 420 causes the strap 1103 to tighten or loosen around the user's hand. For example, since the strap 1103 is attached to the motion stabilizer device 150 at its first end, pulling the strap 1103 at its second end through the chamber tightens the strap 1103. Conversely, applying the opposite force or movement (pushing the second end through the chamber) loosens the strap 1103.When the force acting on the roller wheel 420 towards the locking spring 410 is released, the locking spring 410 again deforms the strap 1103 inside the chamber towards the roller wheel 420 and forces the strap 1103 to abut against the first locking edge 415a and the second locking edge 415b to lock the strap 1103 to the current setting and tightening. Furthermore, for the strap 1103 with its first end attached in an adjustable or dynamic manner to the motion stabilizer device 150, the user can tighten the strap 1103 to a first resistance control point where the strap 1103 is taut against the back of the user's hand (for example, by rolling the roller wheel 420). Next, an additional bearing of the roller wheel 420 causes a translation of the attachment point of the first end of the strap 1103 towards the housing cap 415.This reduces the diameter of the loop along one axis of the motion stabilizer device by 150 for a more secure or tighter fit with a narrow width around the user's hand.

[0057] Figure 6 shows an illustration of a strap adjustment system 405b with a locking pin 430, according to an embodiment of this disclosure. In one embodiment, the strap adjustment system 405b includes the locking pin 430, a pivot point 435, the housing cap 415, and the Roller wheel 420. The strap 1103 passes through the first and second openings formed between the handle portion 151 and the housing cap 415. The locking pin 430 and the roller wheel 420 are positioned between the first and second openings in the chamber. Specifically, the strap 1103 is not deformed or deflected within the chamber to prevent movement of the strap 1103.

[0058] In one embodiment, the strap 1103 has teeth on its first side, and the locking pin 430 has a shape complementary to the teeth. The locking pin 430 is configured to butt against and mate with one of the teeth when it is in the locked or engaged position. The locking pin 430 can be attached to a lever arm at one end, with the roller wheel 420 attached to a second end of the lever arm. The fulcrum 435 is located between the locking pin 430 and the roller wheel 420, and the lever arm is attached to the fulcrum 435. Consequently, the lever arm pivots about the attachment point on the fulcrum 435, causing the locking pin 430 and the roller wheel 420 to move in opposite directions relative to each other. As shown in [Fig.[6] When the roller wheel 420 is moved in a direction towards the strap 1103 (upwards), the locking pin 430 can move away from the strap 1103 (downwards) and disengage from the teeth. In particular, it is possible to apply a force to drive the locking pin 430 towards the strap 1103 (upwards), such as a spring force or a magnetic force, which then constantly drives the roller wheel 420 away from the strap 1103 (downwards) via the pivot point of the support 430.

[0059] Again, the roller wheel 420 includes the axle around which the roller wheel 420 rotates. The axle is attached here to one or both ends of the lever arm (or lever arms when the axle is attached to both ends of the axle). The roller wheel 420 is configured to come into contact with the strap 1103 along the first side of the strap 1103. In one embodiment, the roller wheel 420 also has teeth of a shape complementary to the teeth on the strap 1103, thus ensuring more secure translation of the strap 1103 when the roller wheel 420 is forced upward to come into contact with the strap 1103 and then rotated left or right to tighten or loosen the strap 1103.

[0060] In one embodiment, when the roller wheel 420 is forced into contact with the strap 1103, the locking pin 430 disengages or moves to the unlocked position due to the fulcrum, allowing the strap 1103 to move freely. Simultaneously, the roller wheel 420 comes into contact with the strap, and when a force is applied to rotate the roller wheel 420, the roller wheel 420 translates the strap 1103 to the left or to the right. For example, as As described previously, the user can place the motion stabilizer device 150 on a flat surface with the roller wheel end 420 of the motion stabilizer device 150 proximal to the flat surface. The user then pushes downward with additional force to drive the roller wheel 420 in a direction toward the strap 1103, which releases the locking pin 430 from the strap 1103. The user then moves the motion stabilizer device 150 left or right to tighten or loosen the strap 1103 around their hand. Once the strap 1103 has reached the desired setting, the user lifts the motion stabilizer device 150 from the flat surface, which (via the force of the spring by applying pressure to the locking pin 430 towards the strap 1103) returns the locking pin 430 to the locked or engaged position and prevents the strap 1103 from adjusting further.

[0061] Figure 7 shows an illustration of a strap adjustment system 405c with a ratchet knob 445, according to an embodiment of this disclosure. In one embodiment, the strap adjustment system 405c comprises the ratchet knob 445, a ratchet wheel 440, and a locking ratchet 450. The strap 1103 passes through the first and second openings formed between the handle portion 151 and the housing cap 415. The ratchet wheel 440 is disposed adjacent to the strap 1103, as arranged along the handle portion 151, and makes contact with the strap 1103 on the second side of the strap 1103 (as shown). In one embodiment, the ratchet wheel 440 is arranged along the housing cap 415 and comes into contact with the strap 1103 on the first side of the strap 1103.As shown, the ratchet wheel 440 pushes the strap 1103 towards the housing cap 415 to achieve sufficient friction between the ratchet wheel 440 and the strap 1103. As described previously, the strap 1103 may optionally include teeth that can butt against and mate with complementary features formed on the ratchet wheel 440 to provide additional security in the translation of the strap 1103 via a rotation of the ratchet wheel 440.

[0062] In one embodiment, the ratchet wheel 440 is configured to abut against the strap 1103 and translate the strap 1103 laterally (to the left or right) by a rotation of the ratchet wheel 440. For this purpose, the ratchet button 455 is disposed on an outer surface of the housing cap 415 and configured to move in a direction toward and away from the ratchet wheel 440. To rotate the ratchet wheel 440, the ratchet button 445 is mechanically coupled to the ratchet wheel 440 and configured to be depressed to cause a rotation or ratcheting of the ratchet wheel 440. For example, a series of gears and screws can translate the linear movement of the ratchet button 445 into the rotation of the ratchet wheel 440. Pressing the ratchet button 445 also allows the strap 1103 to be simultaneously held in its current position by the locking pawl 450. The locking pawl 450 is configured to engage with the ratchet wheel 440 and prevent its rotation. The locking pawl 450 can be applied to the ratchet wheel 440 by means of, for example, a spring or magnetic force. In particular, pressing the ratchet button 445 can result in a greater force than the locking pawl 450 exerts on the ratchet wheel 440, thus rotating the ratchet wheel 440 and moving the strap 1103.It may be appreciated that the ratchet button 445 can be disposed along other external surfaces of the motion stabilizer device 150, for example along an external surface of the handle portion 151 so that the user can use a finger to depress the ratchet button 445.

[0063] In one embodiment, the locking pawl 450 is configured to come into contact with the strap 1103 and prevent the strap 1103 from moving (and consequently, prevent the ratchet wheel 440 from rotating). The locking pawl 450 can be applied to the strap 1103, for example, by a spring force or a magnetic force. In particular, depressing the ratchet button 445 can result in a greater applying force than the locking pawl 450 can achieve on the strap 1103, thus allowing the strap 1103 to move.

[0064] In one embodiment, the ratchet button 445 is configured to return to a starting position via, for example, a spring or a magnetic force when the force required to depress the ratchet button 445 is reduced. Thus, the ratchet button 445 can be depressed multiple times to rotate the ratchet wheel 440 (and release the locking pawl 450) to translate the strap 1103. Each time the ratchet button 445 is depressed, the ratchet wheel 440 rotates and translates the strap 1103. Then, the locking pawl 450 prevents further translation of the strap 1103 indirectly by preventing rotation of the ratchet wheel 440 and / or directly by preventing translation of the strap 1103, for example, by friction.

[0065] In one embodiment, multiple presses of the ratchet knob 445 tighten the strap 1103 around the user's hand. For example, the user can grasp the motion stabilizer device 150 along the handle portion 151, position the ratchet knob 445 proximal to a flat surface, such as a table, and apply force toward the flat surface to press the ratchet knob 445 as many times as necessary to translate the strap 1103 and tighten the strap 1103 around their hand. When a desired adjustment is achieved, the user can stop pressing the ratchet knob 445.

[0066] In one embodiment, the motion stabilizer device 150 can include a loosening feature, such as another button, which the user can engage to release or unlock the ratchet wheel 440 of the strap 1103 or the locking ratchet 450 of the strap 1103, thus allowing the strap 1103 to move freely.

[0067] In one embodiment, a force can be applied to the strap 1103 in the opposite direction that overcomes the locking force of the locking ratchet 450 on the ratchet wheel 440, the locking force of the locking ratchet 450 on the strap 1103, or the locking force (for example, a friction force) between the ratchet wheel 440 and the strap 1103. For example, the user can fix the motion stabilizer device 150 between their legs and move their hand away from the motion stabilizer device 150 to move the strap 1103 away from the stabilizer device 150, which overcomes any locking force on the strap 1103 and loosens the strap 1103.

[0068] Figure 8 illustrates a strap adjustment system 405d with automated strap adjustment, according to an embodiment of this disclosure. In one embodiment, the strap adjustment system 405d comprises a motor 455, an adjustment wheel 465 connected to the motor 455, processing circuitry, and a button 460. The strap 1103 passes through the first and second openings formed between the handle portion 151 and the housing cap 415. The wheel 465 is disposed adjacent to the strap 1103, as arranged along the handle portion 151, and makes contact with the strap 1103 on the second side of the strap 1103 (as shown). In one embodiment, the wheel 465 is arranged along the housing cap 415 and comes into contact with the strap 1103 on the first side of the strap 1103.As shown, the wheel 465 pushes the strap 1103 towards the housing cap 415 to achieve sufficient friction between the wheel 465 and the strap 1103. As described previously, the strap 1103 may optionally include teeth that can butt against and mate with complementary features formed on the wheel 465 to provide additional security in a translation of the strap 1103 via a rotation of the wheel 465.

[0069] The motor 455 can be disposed in the handle portion 151, such as at one end of the handle portion 151 proximal to the strap 1103. The processing circuitry is electrically connected to the motor 455 and the button 460 and configured to actuate the motor 455. The button 460 is disposed, for example, along the outer surface of the housing cap 415 (as shown) or on another outer surface of the motion stabilizer device 150 where the user can actuate the button 460 with their finger.

[0070] In one embodiment, the button 460 is electrically connected to the processing circuitry and configured to send an electronic signal to the circuitry. a processing mechanism to actuate the motor 455 when it is pressed. The motor 455, being mechanically connected to the adjusting wheel 465, rotates the adjusting wheel 465 to move the strap 1103. Again, the motor 455 (similar to the ratchet pinion 440 and the ratchet knob 445) can be mechanically connected to the adjusting wheel 465 via a set of gears and / or screws that convert a mechanical output from the motor 455 into a rotation of the adjusting wheel 465.

[0071] In one embodiment, pressing the button 460 in predetermined patterns can result in different actuations of the motor 455. For example, a single press of the button 460 can cause the motor 455 to move the strap 1103 in one direction, and a double press of the button 460 in rapid succession can cause the motor to move the strap 1103 in a second direction. In doing so, the single or double press can tighten or loosen the strap. The motor 455 can be configured to operate for a predetermined time or continuously until another action is performed on the button 460. For example, after the double press of button 460, the motor 455 can rotate the setting wheel 465 until the button 460 is pressed again (for example, a single press or another double press), at which point the motor 455 can stop.

[0072] In one embodiment, the motor 455 includes a force sensor 470 configured to determine a resistance force of the motor 455 as it acts on the adjustment wheel 465 and thus on the strap 1103. For example, the motor 455 can rotate the adjustment wheel 465 to tighten the strap 1103 on the user's hand and, when the force sensor 470 detects that a resistance threshold has been reached, the force sensor 470 can stop the motor 455. By doing so, the strap 1103 will not be tightened beyond a predetermined force and reduces the probability of injuring the user.

[0073] In one embodiment, the PCBA 1302 is communicatively coupled to a remote processing device and configured to update the remote processing device with respect to the layout of the motion stabilizer 150 and other components, such as the button 460 and its actuation. In one embodiment, the remote processing device is configured to receive data from the PCBA 1302 and transmit instructions to the PCBA 1302 based on the layout of the motion stabilizer 150. In one embodiment, the remote processing device is configured to receive user input regarding layout settings, such as a setting for the actuation of the button 460 and / or the resistance threshold, before instructing the PCBA 1302 to adjust the strap 1103 (for example, via the motor 455).In one embodiment, the PCBA 1302 (via the included sensors) detects the unlocking force and other related sensor data and transmits the related sensor data to the . The remote processing device waits to receive instructions from the remote processing device based on relevant sensor data. Upon receiving instructions from the remote processing device, such as to tighten or loosen the strap via motor 455 according to the associated sensor data, the PCBA 1302 adjusts the strap 1103.

[0074] Figure 9 shows an illustration of the strap adjustment system 405 with the adjustable or dynamic strap attachment 1103, according to one embodiment of this disclosure. In one embodiment, as described above, the attachment location at the first end of the strap 1103 can be dynamic or adjustable to allow for further customization to the width of the user's hand. As shown, the strap 1103 is attached or secured to an adjustable strap attachment 475 and loops around the back of a hand 499. The user can tighten the strap 1103 at the first resistance control point where the strap 1103 is held taut against the back of the user's hand (for example, by rolling the roller wheel 420, ratcheting the strap 1103 via the ratchet button 445, activating the motor 455 via the button 460, etc.).At this stage, the first end of the strap 1103 at the adjustable strap attachment 475 may have remained in the same position. Subsequently, additional effort to tighten the strap 1103 causes the adjustable strap attachment 475 (and therefore the first end of the strap 1103) to translate towards the housing cap 415. This reduces the diameter of the loop along an axis of the motion stabilizer device 150 for a more secure or tighter fit with a narrow width around the hand 499. For example, the strap 1103 and the adjustable strap attachment 475 can be translated into a second resistance control point where further tightening of the strap 1103 is prevented to avoid injury.
