The present disclosure relates, generally to gloves having sensing and/or control features. In one aspect, the present disclosure relates to gloves incorporating pressure sensing systems. In another aspect, the disclosure relates to pressure sensing systems and enabling electronic devices and systems for detecting and monitoring hand position and gripping pressure relative to a handheld object and for detecting and tracking hand position and orientation during movement of the hand and the object.
Various types of sensing systems have been incorporated in shoes, insoles, socks and garments for monitoring various physiological parameters for various applications, including recreational, sporting, military, diagnostic and medical applications. Medical applications for sensing pressure, temperature and the like for purposes of monitoring neuropathic and other degenerative conditions with the goal of alerting an individual and/or medical service providers to sensed parameters that may indicate the worsening of a condition, lack of healing, and the like, have been proposed. Footwear-related sensing systems directed to providing sensory data for patients suffering from neuropathy, for gait analysis, rehabilitation assessment, shoe research, design and fitting, orthotic design and fitting, and the like, have been proposed.

Sensor-enabled gloves have also been proposed. U.S. Pat. No. 5,771,492 discloses an electronic golf glove training device, for example, that incorporates sensors in the form of mechanical, pressure sensitive switches located on a glove palm, thumb, finger or dorsal region. Electronic and sound-generating components are provided in a pocket located on the back of the glove and an audible signal is sounded when one of the switches is open, indicating a loss of pressure against one of the switches.

In one aspect, sensor systems of the present invention comprise one or more sensor(s) mounted to/in/on or incorporated in or associated with (any of these arrangements being referred to as “associated with”) a flexible and/or pliable substrate that may be constructed as a (full or partial) glove, or another type of covering for the hand(s). The term “glove,” as we use it herein, refers to any type of covering for a hand, whether it covers the hand fully or partially. The term “sensor,” as we use it herein, refers to sensors as described herein, as well as means for sensing as that term may be construed to extend to sensors as described herein as well as other, additional types of sensors.
In one aspect, sensors associated with the substrate are capable of sensing a physiological parameter of the underlying skin or tissue; in another aspect, sensors are capable of sensing force or pressure exerted on or against the sensor by an underlying skin or tissue, and/or or by an object external to the body. Each sensor is electrically connected, (optionally) via one or more flexible leads, to a flexible conductive trace associated with the substrate, and conductive traces terminate at conductive signal transfer terminals associated with the substrate. Thus, sensor systems and sensing devices described herein preferably comprise at least one flexible sensor (or means for sensing), (optionally) at least two flexible leads, and at least two flexible traces associated with a pliable substrate that is or may be fashioned as a (full or partial) glove.
One or more of the sensor(s), flexible leads, and conductive traces is preferably stretchable and/or elastic, as well as being flexible and pliable, without diminishing the function or operating lifespan of the sensor, flexible lead or conductive trace. In some embodiments, the sensor(s), flexible leads and conductive traces may all comprise flexible, pliable electrically resistive and/or conductive fabric, thread or yarn materials. Gloves incorporating such sensor systems and sensing devices may be comfortably worn by users under many conditions, providing real time monitoring of conditions at or near body surfaces and reporting of the condition(s) to the user, a coach or teacher, colleagues, the general public or a selected audience, and/or a clinician.
The signal transfer terminal(s) on the substrate (e.g., glove) may be matingly received in signal receipt terminals associated with a Dedicated Electronic Device (DED) that, in some embodiments, is attachable to the substrate (e.g., glove) and serves as a (temporary or permanent) data collection device. The DED may also (optionally) house batteries or other energy storage devices and serve as a sensor charging device. The DED may have the capability of communicating with one or more external electronic device(s), such as a smartphone, personal computing device/display, host computer, centralized data processing system, or the like for signal transfer, processing, analysis and display to a user and/or others. In some embodiments, the external electronic device, and/or the DED, communicates with an external, hosted computing system (operated, e.g., at a centralized, hosted facility and/or in the “Cloud”) that provides additional data storage and/or processing and/or analysis, formulates feedback, notifications, alerts, and the like, that may be displayed to the user, a coach or teacher, colleagues, the general public or a selected audience, and/or a clinician, through one or more computing and/or display devices.
In some embodiments, one or more pressure sensor(s) associated with a substrate fashioned as a glove detect changes in voltage or resistance across a surface area that is associated with force exerted on the sensor, which is related to pressure (as force per unit surface area) and/or shear. In some embodiments, FSR (Force Sensitive Resistor) or piezo-resistive sensors may be used. One type of piezoresistive force sensor that has been used previously in footwear pressure sensing applications, known as FLEXIFORCE® sensors, can be made in a variety of shapes and sizes, and measure resistance, which is inversely proportional to applied force. These sensors use pressure sensitive inks with silver leads terminating in pins, with the pressure sensitive area and leads sandwiched between polyester film layers. FLEXIFORCE® sensors are available from Tekscan, Inc., 307 West First Street, South Boston, Mass. 02127-1309 USA. Other types of sensors may also be integrated in or associated with various substrate materials from which gloves are constructed (e.g., fabrics, leathers, sheet materials, and the like), including sensors providing data relating to temperature, moisture, humidity, stress, strain, galvanic skin response, heart rate, respiratory rate, blood pressure, blood oxygen saturation, blood flow, local gas content, bacterial content, multi-axis acceleration, orientation, positioning, and the like. Auxiliary sensors may also be associated with other substrates or auxiliary devices worn by a user, and data from such auxiliary sensors may be used with sensor systems as described herein to formulate feedback. Many suitable sensors are known in the art and may be adapted for use in sensing systems described herein.
In some embodiments, pressure sensors incorporated in sensing systems of the present invention comprise non-silicon-based materials such as pliable, piezo-resistive “e-textile” fabric material(s), threads or yarns, while associated leads and/or conductive traces comprise non-silicon-based materials such as pliable, conductive “e-textile” fabric materials, threads or yarns. In some embodiments, sensors and/or associated leads and/or conductive traces incorporated in sensing systems of the present invention comprise pliable, conductive fabric materials, threads or yarns that are substantially isotropic with respect to their flexibility and/or stretch properties. By “substantially” isotropic, we mean to include materials that have no more than a 15% variation and, in some embodiments, no more than a 10% variation in flexibility and/or stretch properties in any direction, or along any axis of the material. Suitable materials, such as piezo-resistive fabric sensors, coated and/or impregnated fabrics, including metallic coated fabric materials and fabric materials coated or impregnated with other types of conductive formulations, are known in the art and a variety of such e-textile materials may be used. In some embodiments, pressure sensors and conductive leads used in sensing systems described herein comprise the same pliable e-textile fabric materials having resistivity and conductivity properties, with resistive properties being used for sensing and conductive properties being used for signal transfer to conductive traces.
E-textile fabrics comprising a knitted nylon/spandex substrate coated with a resistive and/or conductive formulation are suitable for use, for example, in fabricating biometric pressure sensors and in other applications requiring environmental stability and conformability to irregular configurations. One advantage of using these types of e-textile fabric sensors is that they perform reliably in a wide variety of environments (e.g. under different temperature and moisture conditions), and they're generally flexible, durable, washable, and comfortably worn against the skin. Suitable flexible e-textile fabric materials are available, for example, from VTT/Shieldex Trading USA, 4502 Rt-31, Palmyra, N.Y. 14522, from Eeonyx Corporation, 750 Belmont Way, Pinole, Calif. 94564. E-textile fabrics are also being developed by Footfalls & Heartbeats Ltd., Ground Floor, Shed 20, 139 Quay Street, Princes Wharf, Auckland 1010, New Zealand.
Techniques for deriving force and/or pressure measurements using e-textile resistive and/or conductive fabric materials are known in the art and various techniques may be suitable. See, e.g., http://www.kobakant.at/DIY/?p=913. Techniques for measuring other parameters using e-textile fabric materials, such as humidity and temperature measurements, are also known and may be used in sensing systems of the present invention. See, e.g., http://www.nano-tera.ch/pdf/posters2012/TWIGS105.pdf. Moreover, techniques for detecting and measuring shear are also available. Fabric sensors of the present invention may thus be capable of monitoring various parameters, including force, pressure, shear, parameters derivative of or related to force, pressure and shear, humidity, temperature, gas content, and the like, at the site. Additional monitoring capabilities may be available using fabric sensors as innovation in fabric sensors proceeds and as nano-materials and materials incorporating nano-structures are developed and become commercially feasible. E-textile sensors capable of providing proportional pressure signals (e.g., proportional pressure sensed over a surface area), and/or providing pressure signals that correlate with spatial locations on a surface area of the e-textile sensors are preferred.
Flexible (and optionally stretchable or elastic) resistive or conductive e-textile fabric sensor(s), leads and/or traces are associated with a substrate such as fabric, (natural or synthetic) leather, or another material that's substantially non-conductive and pliable, is capable of being comfortably worn (directly or indirectly) against the skin, and is capable of moving in concert with the physiological structures the substrate is covering (e.g., fingers, thumbs and palms of the hand, and similar structures of other body areas). The term “fabric” or “sheet material” as used herein, refers to many types of pliable materials, including traditional (natural or synthetic) fabrics comprising woven or non-woven fibers or strands, as well as fiber reinforced sheet materials, and other types of flexible sheeting materials composed of natural and/or synthetic materials, including flexible natural and synthetic leather materials, various types of plastic sheeting material, pliable thermoplastic, foam and composite materials, screen-like or mesh materials, and the like. The substrate may comprise a sheet material fabricated from flexible material that is stretchy and/or elastic. The substrate may be substantially isotropic with respect to its flexibility and/or stretch properties. By “substantially” isotropic, we mean to include materials that have no more than a 15% variation and, in some embodiments, no more than a 10% variation in flexibility and/or stretch properties in any direction, or along any axis of the material.
For many glove and glove-like applications, one or more e-textile sensor(s) and/or sensing devices may be associated with a substrate that is in the form of a glove or a substrate that can be finished as a glove by sewing, bonding, weaving, or the like. The e-textile sensor(s) are positioned on inner, outer or intermediate location(s) with respect to the substrate surface for contacting portions of an individual's hand (e.g., finger(s), palm, etc.), directly or indirectly, during use and for detecting the position and/or magnitude of force and/or pressure exerted against the sensor(s) by an individual's hand, and by a handheld object. The sensor(s) may detect other parameters sensed at or near a skin surface. In some embodiments, conductive threads, yarns and/or e-textile fabric sensors may be sewn through or knitted into the substrate, sandwiched between two or more substrate layers, or otherwise incorporated in fabric, leather or other substrates. In some embodiments, e-textile fabric sensors may be partially or fully enclosed in a flexible barrier material or envelope to protect the sensor(s) from excessive moisture or other unfavorable ambient conditions.
The use of e-textile pressure sensors provided at selected predetermined locations on a glove provides precise identification of the position and grip pressure of a the user's hand with respect to a hand-held object, such as a golf club, another sports-related object (e.g., racket, bat, stick, etc.), a tool, machine or other occupational object, or the like. Feedback devices and analytics may be provided to alert the user to poor grip positioning of the object in the hand, inappropriate grip pressures exerted (statically or dynamically, during motion of the hand and object), and the like. Similarly, sensor-enabled gloves used for weightlifting, lifting or pushing objects, or the like, may provide precise data relating to force exerted against specific sensor locations. The use of e-textile pressure sensors provided at selected predetermined locations on a glove may also provide precise data relating to the location and magnitude of impact forces exerted against the sensors and sensor location on a hand (in a boxing glove, for example).
Each sensor, such as a resistive pressure sensor, may be associated with two conductive leads, and each of the leads may be electrically connected to a conductive trace conveying electrical signals to a signal transfer terminal. In some embodiments, resistive pressure sensors may be directly connected to conductive traces. Resistive e-textile fabric sensors, as previously described, may be electrically connected to conductive leads, or may have a flexible fabric lead associated with or incorporated in (e.g., formed as part of) the fabric sensor footprint. The sensors and/or conductive leads are electrically connected to flexible conductive traces, which may comprise a variety of flexible conductive materials, such as a conductive fabric, thread, yarn, or the like. In some embodiments, the conductive traces are stretchable and/or elastic, at least along the longitudinal axis of the conductive trace. In some embodiments, conductive traces comprise a conductive e-textile fabric, thread or yarn having high electrical conductivity, such as silver coated e-textile materials, and may be sewn to or woven through the underlying substrate material, or bonded to the underlying substrate material using adhesives, heat bonding or non conductive threads. Suitable conductive fabric, thread and yarn materials are known in the art and are available, for example, from the vendors identified above.
Each of the conductive traces terminates in a signal transfer terminal that is mounted to/in/on, or associated with (collectively referred to as “associated with”), the substrate and can be interfaced with a mating signal receipt terminal of a dedicated electronic device (DED) providing energy, data storage, processing and/or analysis capabilities. In general, conductive traces and signal transfer terminals are arranged in a predetermined arrangement that corresponds to the arrangement of signal receipt terminals in the DED. Many different types of signal transfer and receipt terminals are known and may be used in this application. In one exemplary embodiment, signal transfer and receipt terminals may be mounted in cooperating fixtures for sliding engagement of the terminals. In another embodiment, signal transfer terminals may be provided as conductive fixtures that are electrically connected to the conductive trace (and thereby to a corresponding sensor) and detachably connectible to a mating conductive fixture located on the DED. The mating terminals may comprise mechanically mating, electrically conductive members such as snaps or other types of fasteners providing secure mechanical mating and high integrity, high reliability transfer of signals and/or data. In some embodiments, convenient and secure mating of the terminals may be enhanced using magnetic mechanisms or other types of mechanisms that help users to properly connect/disconnect the mating terminals with minimal effort.
The DED, in addition to having data recording, processing and/or analysis capabilities, may incorporate an energy source such as a battery providing energy for data recording, processing and/or analysis, as well as providing energy for operation of one or more of the sensor(s). The energy source is preferably a rechargeable and/or replaceable battery source. The DED generally provides a lightweight and water-tight enclosure for the data collection and processing electronics and (optional) energy source and provides signal receiving terminals that mate with the signal transfer terminals communicating with the sensor(s) for conveying data from the sensors to the DED.
DEDs having signal receipt terminals that mate with the signal transfer terminals associated with the substrate may take a variety of form factors, depending on the form factor of the underlying sensing substrate and/or the conditions and location of the device during use. When sensors are incorporated in a glove or glove-like form factor for monitoring conditions sensed at the hand, for example, the signal transfer terminals may be arranged in proximity to one another at a back of the hand location on the glove, and the DED may have a form factor of a small dongle or tab, with mating signal receiving terminals sized and configured for mating with the underlying signal transfer terminals. In one embodiment, the signal transfer terminals and (detachable) DED may be located on the back of the glove in a wrist area in proximity to or below an adjustment tab. In another embodiment, the signal transfer terminals (and detachable DED) may be located on an adjustment ta, such as on a flap that adjustably tightens the glove.
The DED may be provided as a substantially flexible or a substantially rigid component, and it may take a variety of forms. In one embodiment, the DED may comprise a housing that can be positioned in a pocket provided on a surface of the glove that provides secure positioning of the DED during movement, while allowing removal of the DED for charging and other purposes. In another embodiment, the DED may comprise a housing that mechanically mates with a base fixed or attachable to the surface of the glove and providing access to the signal transfer terminals on the glove. Various alternative systems for securely mounting the DED on an underlying glove and for connecting the signal transfer and signal receipt terminals may be provided.
The DED preferably communicates with and transfers data to one or more external computing and/or display system(s), such as a smartphone, computer, tablet computer, dedicated computing device, or the like, using wired and/or wireless data communication means and protocols. The DED and/or an external computing and/or display system may, in turn, communicate with a centralized host computing system (located, e.g., in the Cloud), where further data processing and analysis takes place. Substantially real-time feedback, including data displays, notifications, alerts and the like, may be provided to the user, coach, or the like. In some embodiments, the DED may store the data temporarily to a local memory, and periodically transfer the data (e.g., in batches) to the above mentioned external computing and/or display system(s). Offline processing and feedback, including data displays, notifications and the like may be provided to the user, caretaker, and/or clinician according to user, caretaker and/or clinician preferences.
Additional sensors and electronics may be provided in gloves and/or in DEDs as described herein. In some embodiments, for example, one or more accelerometer(s) (e.g., single and/or multi-axis accelerometer(s)) and/or gyroscope(s) may be provided for movement and/or orientation sensing in addition to the sensor(s) for detecting hand position relative to an object, force and/or pressure sensing. Sensors that detect physiological conditions such as stress, sweat, moisture, conductivity, and the like, may also be provided. Various types of location (e.g., GPS), optical and/or audio detectors (e.g., microphone(s)) and sensors may also be used. These electronic devices are typically located in the DED, where power, memory, processing and/or analytical capabilities are available. Additional sensors and electronic devices may also be provided.
In some embodiments, for example, a gyroscope or another orientation sensor may be provided in a DED or sensor-enabled glove to provide data relating to hand (and object) orientation, statically and/or dynamically during movement of the hand (and object). Orientation data is valuable, for example, in sporting applications such as golf, when the ball is addressed prior to swinging. The “correct” orientation of the hands and golf club grip when the ball is addressed during putting, for example, is an upright, vertical orientation of the stem and grip of the golf club. The “correct” orientation of the hands and golf club grip when the ball is addressed during driving is an entirely different orientation. Real-time feedback provided to the user from sensing systems/DED/analytical facilities described herein may present data and corrective feedback to the user, e.g., by alerting the user when his or her hand/grip position is out of alignment, improving the user's play and reducing injuries. Grip pressure and the location and distribution of grip pressure during play and ball striking is also important. Orientation and grip pressure sensing of other sporting implements (various types of rackets (e.g., tennis, racket ball, squash, and the like), bats (e.g., baseball and cricket), sticks, (e.g., hockey and lacrosse), is also important and may also be detected using sensing systems as described herein.
In some embodiments, one or more accelerometer(s) may also collect data relating to various aspects of motion of the hand(s) and object during movement. Incorporation of a gyroscope and/or accelerometer in a glove or DED associated with a glove may also provide data relating to the 3D motion of the hands (and club) during the swing. In one embodiment, a 3D representation of the plan of the swing, as detected by the position and movement of the golfer's hand(s) and the golf club grip may be detected and displayed. In yet additional embodiments using location sensors, geo-referencing tools, and other sensors (e.g., audio), swings and/or ball strikes may be detected and mapped (e.g., on specific golf courses), providing the user with a stroke count, precise information relating to the number of swings taken, swing (and ball) locations, etc. Data collected may be stored, reviewed by the user, or a coach, compared to the user's data or to desired “standards,” data collected from other users, etc.
In operation, an initial authentication routine and/or user identification system matches the DED and associated sensing system (e.g., the collection of sensor(s) associated with an underlying substrate) with the user, coach or the like, and may link user information or data from other sources to a software- and/or firmware-implemented system residing on the external computing system. The external computing device may itself communicate with a centralized host computing system or facility where data is stored, processed, analyzed, and the like, and where output, communications, instructions, commands, and the like may be formulated for delivery back to the user, coach, or the like, through the external computing device and/or the DED.
Calibration routines may be provided to ensure that the DED and connected related sensor system are properly configured to work optimally for the specific user. Configuration and setup routines may be provided to guide the user to input user information or data to facilitate data collection, and various protocols, routines, data analysis and/or display characteristics, and the like, may be selected by the user to provide data collection and analysis that is targeted to the specific user. Notification and alarm systems may be provided, and selectively enabled, to provide messages, warnings, alarms, and the like to the user, substantially in real-time, based on sensed data.
The use of similar types of sensors and sensing systems in garments such as socks and in association with substrates such as bandages, sheets and other flexible substrates, is described in detail in commonly owned U.S. Pat. No. 8,925,392 and in PCT Patent Publication WO2015/017712 A1, which are incorporated herein by reference in their entireties.
It will be understood that the appended drawings are not necessarily to scale, and that they present simplified, schematic views of many aspects of systems and components of the present invention. Specific design features, including dimensions, orientations, locations and configurations of various illustrated components may be modified, for example, for use in various intended applications and environments.
E-textile fabric sensors are mounted to, or associated with, an underlying substrate (e.g., natural or synthetic leather, a fabric or sheet material, or the like) in a variety of ways, including sewing (e.g., stitching), adhesive bonding, thermal bonding, and the like. It will be appreciated that although rectangular and L-shaped polygonal sensor/lead combinations are illustrated, fabric sensors having a variety of sizes and configurations may be provided. Leads having the same properties as the sensors may be used, or other types of leads may be employed. It will also be appreciated that the arrangement of leads with respect to sensor(s) may vary, depending on the properties, size and configuration of the sensor and lead components and that, in some embodiments, sensors may be connected directly to traces without using designated leads.
In some embodiments, one or more protective layers or materials may be provided to protect one or more sensor(s) and, optionally, the associated leads, and all or portions of conductive traces, from contact with liquids, body fluids or other materials present in the ambient environment (e.g., moisture, rain, etc.), while preserving the core resistive features and functions of the sensor(s). A protective barrier may comprise a liquid impervious or substantially liquid impervious material, such as a generally thin plastic sheet material or a composite sheet material, that doesn't interfere with the sensing capacity of the sensor. By “substantially” liquid impervious we mean that liquid penetration of the material is insubstantial enough to affect the features and functions of the sensor(s). The protective barrier may optionally be breathable and/or gas permeable. Many such liquid impervious barrier materials are known. In some embodiments, a protective barrier may be provided on one surface of the sensor; in some embodiments, a sandwich- or envelope-type barrier that substantially seals the sensor in a substantially liquid impermeable envelope or pouch may be used.
E-textile sensors as disclosed herein are electrically connected to conductive traces, as described. The conductive traces terminate in conductive terminals, which are typically associated with the substrate (e.g., glove) and provide connectivity to mating conductive terminals provided in a DED. In many applications, sensors, leads and/or traces may be associated with an interior surface of a substrate and conductive terminals CT1, CT2 may be provided as conductive elements, such as conductive mechanical snaps, that penetrate the substrate material from the interior to the exterior substrate surface. In some embodiments, signal transfer and signal receipt terminals have mechanically and magnetically detachable mating capabilities. The polarity of magnetic components may be arranged to provide male and female connectors that are connectable only when magnetically aligned in a predetermined orientation, which may facilitate user connection of the mating terminals in an appropriate orientation. In this exemplary embodiment, properties of the magnetic field may be used to create terminals that can only connect in one orientation: in this way, the user is guided to properly connect signal receiving terminals provided on the DED to the sensor system(s) associated with the underlying substrate.
It will be appreciated that other types of sensors may be integrated in the sensor system that contact the underlying body area (directly or indirectly), and that additional conductive terminals may be provided for transmission of signals and/or data from other types of sensors. It will also be appreciated that multiplexing systems may be implemented and that multiple sensors and sensor traces may be associated with a single conductive terminal. In some embodiments, the mating and detachment of terminal interfaces on the substrate and DED may operate as switches that are switched on and off abruptly by an external driving force from one switch position (e.g., “activated” when the terminals are connected) to a second position (e.g., “off,” when the terminals are detached).
Sensing systems, as disclosed herein, may be used in connection with various types of substrates and garments, as previously described. In specific embodiments disclosed herein, such sensing systems are embodied in gloves and other close-fitting articles configured to be worn on a hand, or on part of a hand. Sensor-enabled gloves may be used and designed specifically for various applications in which an object is gripped to provide data relating to hand position and/or grip pressure on the object, in both static and dynamic settings. This capability enables a user wearing a sensor-enabled glove as described herein to analyze his or her grip on the object before, during and/or after movement of the object.
These examples show how using position and grip pressure sensors in these locations, in combination with a DED and/or external data processing and analytical facility and data analysis, provides detection of golf club grip placement and grip pressure in the user's hand. Data relating to the grip placement and pressure may be detected statically, at one or more time points, and may also be detected and monitored dynamically over periods of time, such as during golf swings, for tracking, in real-time, how the grip placement and grip pressure varies during golf swings. This information may be used by glove wearers, coaches, medical professionals, colleagues and the like, to improve golf club hand positioning and grip pressure, reduce injuries, etc.
Leads may be provided integrally with and as extensions from sensors 12, 14 and 16 as shown in
Another lead from each sensor (12, 14, 16) is connected, serially, to a common trace 19, which terminates in a dedicated signal transfer terminal 25. This common trace may serve as a ground trace, terminating in a ground terminal. Alternatively, these sensor leads may be connected in parallel to a common ground terminal. It will be appreciated that many different conductive trace arrangements may be used for both signal traces and ground traces.
In some embodiments in which the traces are stitched through the substrate material of the glove, the location and configuration of contrasting trace stitching may correspond to desired positioning of an object (e.g., golf club grip) across the palm, providing a visual guide to the wearer of proper hand and club positioning.
The sensor/lead components may be associated with a palmer component 20 of the glove, as shown, and the signal transfer terminals are associated with an outer or dorsal component 30 of the glove. In the embodiment illustrated in
Different configurations and locations of e-textile sensors may be provided in gloves for different applications.
Leads may be provided integrally with and as extensions from sensors 42, 44 and 46 as shown in
A dedicated electronic device (DED) has signal receipt terminals that mate with conductive signal transfer terminals to provide signal and/or data transfer from the sensor/lead/traces associated with the substrate to the DED. The DED typically comprises a protective housing or case enclosing an interior space containing processing, memory and/or communications components. The DED preferably includes a protective and watertight housing or case protecting the electronic components provided within the housing. The housing may be provided as a substantially rigid or a substantially flexible component and a variety of DED form factors may be provided, depending on the type and arrangement of underlying substrate and signal transfer terminals.
The DED incorporates processing, memory and/or communications functionalities within the housing. A schematic diagram illustrating exemplary DED components and interfaces is shown in
Signals and/or data are communicated from the DED to an external computing facility or device, such as a computer, base station, smartphone, or another bridge device, and/or to a centralized, hosted facility in a remote location, such as in the Cloud or at a centralized data processing and analysis facility. Following data analysis in accordance with predetermined and/or pre-programmed instructions, data output, analysis, notifications, alerts, and the like are communicated from the centralized hosted facility to the bridge device, and/or the DED, as shown. It will be appreciated that this is one exemplary data flow scheme, and that many other work flows may be advantageously used in connection with sensing systems of the present invention.
In some embodiments, the DED may additionally comprise visual indicators or display elements for providing feedback to a user. Additionally or alternatively, signals and/or data may be communicated from the DED to an external computing facility or device, such as a computer, base station, smartphone, or another bridge device, and/or to a centralized, hosted facility in a remote location, such as in the Cloud or at a centralized data processing and analysis facility. Following data analysis in accordance with predetermined and/or pre-programmed instructions, data output, analysis, notifications, alerts, and the like may be communicated from the centralized hosted facility to the bridge device, and/or the DED, as shown in
In one embodiment, the DED may be physically attached to the sensing substrate (e.g., a glove) for data collection and then detached from the sensor terminals and physically mounted (e.g., though a USB or another wired connection), to an external computing and/or display device such as a phone, personal computing device, computer, or the like to download data. In other embodiments, the DED preferably has wireless communication capability (e.g., using Bluetooth, WiFi, or another wireless standard) and transmits signals and/or data to a computing and/or display device wirelessly. The DED may thus be connected through a communication system to an external electronic device having data storage, computing and/or display capabilities. The external computing and/or display device generally hosts client firmware and/or software and processing firmware and/or software for processing, analyzing, communicating and/or displaying data. It will be appreciated that the division of functions and processing, such as data processing, analysis, communications and display functions as between the DED and the external computing and/or display device may vary depending on many factors and is, to at least some extent, discretionary.
In some embodiments, as schematically illustrated in
Additional and different content may be displayed on a display component associated with gloves having other sensing systems. In some embodiments, a display associated with a glove may be provided as an interactive display, such as a touch screen display. When an interactive (e.g., capacitive) touch screen display is provided, glove fingertips having conductive elements may be provided to use with and operate the capacitive display. A variety of glove types, such as sports gloves, outdoor gloves, motor sports gloves, ski gloves, and the like, may be provided with interactive or non-interactive display elements having rigid, curved or flexible components.
Sensor systems enabled in gloves, as described herein, may be used in combination with one or more additional sensor systems mounted for detection of movement and orientation on a glove, on an object gripped by a user (e.g., a golf club), on an auxiliary device attachable to a glove or a golf club, or on a garment, band, or the like wearable by the user. Suitable sensors include (single and/or multi-axis) accelerometer(s) for detecting magnitude and/or direction of the proper acceleration (or g-force), for sensing orientation, coordinate acceleration, vibration, shock, and the like; gyroscopes for detecting and monitoring orientation, angular momentum, and the like; camera(s) or other types of optical sensors and detectors; audio sensors and detectors for detecting sounds, vibrations, and the like, and other types of sensors. Sensors for detecting ambient conditions, such as temperature, humidity, light conditions, barometric pressure, and the like, may also be provided.
In some embodiments, client software and communications systems are hosted on the external computing device (e.g., a computer or a mobile device such as a tablet or smartphone), and provide feedback to and interact with the user, communicating through an Internet connection via web services, to push collected data and retrieve processed data from the service and display (or otherwise communicate) it to the user. The client software may comprise a set of applications that can run on multiple platforms (not limited to personal computers, tablets, smartphones) and sub-components (diagnostics, troubleshooting, data collecting, snap and match, shopping) to deliver a rich and complete user experience.
Additional data may be collected and displayed, as described. Data collected from one or more sensors, such as a multi-axis accelerometer, can be analyzed and provide information relating to the user's dynamic swing motion, and feedback, such as 3D displays and analytical information relating to the 3D swing plane of the hands and handheld object (e.g., golf club) can be provided. Data collected from one or more sensor(s), such as gyroscope(s), can be analyzed and provide information relating to hand and object orientation prior to, during and following movement of the handheld object for monitoring orientation prior to, during and following a user's putting motion, swinging motion, racket stroke, and the like. The use of audio sensor(s) (e.g., a microphone) provided in a sensing system as described herein, or provided in another user device (e.g., smartphone, computing device, camera, etc.) may provide a reference time point for when the ball is hit and may be integrated with other sensed signals to provide a high level of analytical feedback relating to the user's hand position, grip pressure, hand and object motion, and the like, prior to, during and following motion, activity, etc.
For some applications, server software components that apply crowdsourcing logic and/or machine learning technologies may be implemented to identify, profile, and cluster user data. The data may be stored in a database and may be continuously or intermittently updated with incoming user supplied and/or sensor supplied data. An optional software component that provides image and pattern recognition capabilities may also be implemented. This feature may allow a user to input data (e.g. images, external data accessed from databases, etc.) without entering any text input.
Sensor-enabled gloves and related electronics (e.g., DED) and analytical tools (apps, phones, computing and display devices, etc.), as described herein, may be beneficially used in a wide range of applications. Sensor-enabled gloves and related electronics may be advantageously used, for example, in sports applications, including gloves for racket sports (e.g., tennis, badminton, squash, racketball, etc.) and handball, gloves for baseball, and particularly batting gloves, gloves for lacrosse, soccer goalies, boxing and other types of martial arts, weightlifting, cycling, football, skiing, and the like. Sensor-enabled gloves may also be adapted for use as driving gloves, motorcycle gloves, gloves for occupational activities, such as safety work gloves, work gloves, construction gloves, landscaping gloves, factory and transport workers' gloves, mechanic's gloves, and the like. Sensor-enabled gloves as described herein may also be designed for use in electronic gaming applications, and for sensing hand position, grip pressure, hand orientation and/or motion, or the like, during electronic game playing. Military applications for sensor-enabled gloves as described herein are also contemplated. It will be appreciated that the configurations, orientations and types of sensors, and the analytical feedback provided, may differ in these different applications.
In the description provided herein, the term “about” means+/−20% of the indicated value or range unless otherwise indicated. The terms “a” and “an,” as used herein, refer to one or more of the enumerated components or items. The use of alternative language (e.g., “or”) will be understood to mean either one, both or any combination of the alternatives, unless otherwise expressly indicated. The terms “include” and “comprise” are used interchangeably and both of those terms, and variants thereof, are intended to be construed as being non-limiting.
Although specific embodiments have been illustrated and described with reference to the sensors, leads, traces and terminals, described herein, as well as different types of DEDs, data collection, processing and analysis techniques, it will be appreciated that the same or similar types of sensing systems may be adapted for use in other types of applications, in connection with other types of garments, and in non-garment applications. Similar types of pliable e-textile sensors having resistive and/or conductive properties may be applied to or associated with a wide variety of non-conductive underlying flexible substrate materials, including woven and non-woven materials, and incorporated in a variety of sensor systems. Additional exemplary systems are described below, and are non-limiting.
While the present invention has been described above with reference to the accompanying drawings in which particular embodiments are shown and explained, it is to be understood that persons skilled in the art may modify the embodiments described herein without departing from the spirit and broad scope of the invention. Accordingly, the descriptions provided above are considered as being illustrative and exemplary of specific structures, aspects and features within the broad scope of the present invention and not as limiting the scope of the invention.
