The present invention relates generally to an electrode assembly having at least two snap portions. More particularly, embodiments of the present electrode assembly are particularly well suited for receiving, holding and enabling an electrical connection with male ends of a telemetric device. Examples of the present electrode assemblies are integrated within a heart rate monitor belt or garment.
Currently, there are heart rate monitor belts which people can wear underneath their clothing in order to monitor their heart rate. Such belts are typically designed such that a telemetric transmitter is detachably connected to a belt having two electrodes which are in contact with the user's skin in the chest region of the user's torso. The electrodes identify an electric ECG pulse caused by the heart and then the detachable telemetric transmitter transmits data indicative of the user's heart beat with the use of wireless magnetic near field communication or a radio signal to a remote receiver provided with a display. In many instances the remote receiver is provided in the form of a wrist watch, wrist top computer or other similar display carried by a user, typically on the user's wrist.
Since various acceleration and magnetic sensors can be integrated in small and lightweight devices, the telemetric data to be transferred may, instead of or in addition to the heart rate, comprise a plurality of measured variable data, such as working frequency, pedaling rate and pedaling frequency, travel speed, etc. The data to be transferred may additionally comprise data required for the identification of the user and/or the transmitter device.
U.S. application Ser. No. 11/808,391 filed Jun. 8, 2007 and published as US 2007/0285868 which is herein incorporated by reference in its entirety, for instance, discloses a heart rate monitor belt which comprises a plurality of electrodes and a detachable telemetric transmitter.
It is preferably to have a telemetric transmitter which is detachable from a heart rate monitor belt for several reasons. From a consumer point of view, a user is typically sweating while using a heart rate monitor belt and it is therefore advantageous to be able to separate the electronic telemetric transmitter from the belt so that the belt can be washed. From a manufacturing point of view, the process for manufacturing the belt is substantially different from that of manufacturing the transceiver and therefore it is beneficial to be able to manufacture the components separately. Additionally, it is beneficial for one telemetric transmitter to be interchangeable with a plurality of belts.
Though there are several alternative methods for detachably connecting a telemetric transmitter to a heart rate monitor belt, the industry has almost entirely adopted the use of a pair of standard garment snaps. These standard garment snaps typically are mounted on the material of a heart rate monitor belt and virtually their entire thickness of around 4 mm protrudes from the outer surface of the belt.
Due to the existing technology and methods for detachably connecting telemetric transmitters it has not been realistic to incorporate heart rate monitor electrodes in to typical garments. In fact, the primary road block to such incorporation has been the size and bulkiness of the standard garment snaps. No clothing manufacture, nor consumer, has wanted 4 mm protrusions from their garments such as tops, shirts and sports bras.
Therefore, the garment industry has incurred a long felt need for an improved method of detachably connecting a telemetric transmitter to an article of clothing which does not compromise the integrity and utility of the underlying garment. However, the telemetric transmitter manufacturing industry has already adopted certain standards which relate to the use of a pair of male studs on a telemetric transmitter to be detachably snapped in to a pair of snaps on a heart rate monitor belt. As such, it would not be economical to wholly redesign the male portions of telemetric transmitters and the method in which they connect to an object having the necessary electrodes for measuring a user's heart rate.
Thus, there exists a need for a snap which fulfils the requirements of the garment industry but which fits in at least partially with the existing standards of the telemetric transmitter manufacturing industry. However, several critical issues arise when attempting to merely minimize the existing standardized snap. The main issue is the integrity of the connection between the male stud and the snap. Any amount over movement of the male stud within the snap will create electrical noise which makes difficult to impossible to accurately measure parameters such as a user's heart beat. Additionally, as a user is typically involved in strenuous activity while utilizing the product, the connection needs to withstand, and support the telemetric transmitter during such activity. As the depth of the snap decreases, the forces required to insure a reliably stable connection significantly increase.
Further yet, users typically sweat while undergoing strenuous activity wearing the product. As a reliable electrical connection is necessary between the telemetric transmitter and the electrode on the user's skin, it is important to keep the connection moisture free to reduce the likelihood of any shorts. Similarly, the problem is compounded for users who wish to utilize a heart rate monitor under water, for example while swimming or diving.
Therefore, there exist numerous challenges in the art to the development of a means of detachably connecting a telemetric transmitter to a garment having electrodes for monitoring a user's heart beat which aims to satisfy user's need, the garment manufacturer's needs and the needs of telemetric transmitter manufactures.
It is an object of the present invention to provide an electrode assembly.
Electrode assemblies according to the present invention are particularly useful as being integrated in to garments. Electrode assemblies described herein may come in a kit form with a plurality of pieces or in a single, assembled form.
According to certain embodiments, an electrode assembly includes a first electrode having an upper cap portion of a snap on one side, a second electrode having an upper cap portion of a snap on one side, and a linking member having a first base portion of a snap and a second base portion of a snap separated by a non-stretchable material portion, wherein the first electrode and the second electrode are coupleable to their respective first and second base portions of the linking member.
The upper cap portion and base portions form a snap. Snaps according to aspects of certain embodiments of the present invention are extremely thin compared to traditional snaps used with electrodes, for example in typical heart rate monitor belts. The thin size of the snaps lend themselves well to integration into garments so that when the snap is not connected, for example to a telemetric device, e.g. a heart rate monitor device and/or an EMG muscle measurement device, the snaps do not impact the wearability of the garment itself.
It is another object of the present invention to provide a garment with at least one electrode assembly integrated therewith.
Still yet, it is a further object of the present invention to provide a linking member which has at least two portions which form base portions for snaps and which have a higher degree of rigidity compared to a non-stretchable material portion connecting said at least two base portions. The linking member of the present invention allows for easy and reliable integration of multiple electrodes and snaps in to a garment with consistent spacing between the snaps. Additionally, the flexible nature of the non-stretchable material portion according to certain embodiments increases the wearability of a garment having one or more of the electrode assemblies.
A snap 10 in accordance with an embodiment of the present invention is shown in
As discussed herein, a heart rate monitor belt is the combination of electrodes and snaps in such an arrangement that they can be used to determine, measure and/or monitor the heart beat of an individual or animal wearing the belt. A heart rate monitor belt may be a standalone article in the form of, for example, a belt having a plurality of electrodes connected to a pair of snaps which can be worn, for example around the torso of a user. Additionally, a heart rate monitor belt can be integrated within a garment, for example a top or sports bra. As such, a garment having the components necessary for use in monitoring the heart rate of a user similar to a standalone heart rate monitor belt will likewise herein be referred to as a heart rate monitor belt.
A snap 10 in accordance with certain embodiments of the present invention should be integratable within an article. Additionally, the snap 10 should be capable of receiving, holding and enabling an electrical connection with a male end of a telemetric device. A more detailed description of telemetric devices follows below. The snap 10 generally comprises an upper cap portion 12, a base portion 14 and a conductive wire spring 16 as can be seen in
The upper cap portion 12 includes a recess forming at least a portion of the sides 30 of a socket region 20 of the snap. The socket region 20 is for receiving a male end of a telemetric device. The upper cap portion 12 is more clearly seen in
The amount of depression of the flange 26 compared to the top portion can be equal to or approximately equal to the thickness of material 18 which the snap is to be integrated with. Additionally, the amount of depression can be a standard amount which is selected in order to work best with a wide variety of material thicknesses. However, as can be seen in
The recess in the upper cap portion 12 forms a socket region 20. The sides 30 of the recess generally form the sides of the socket region 20. While the sides 30 of the recess can have a plurality of geometries from generally vertical to something more complex, it is advantageous for the side wall geometry to be complementary to the male end of a telemetric transmitter to be detachable connected to the snap 10. Such geometries will be discussed in more detail below.
The socket region is generally formed by the sides 30 of the recess of the upper cap portion 12 and by a bottom, as seen in
In accordance with the present example, the upper cap portion 12 comprises an opening at the bottom of the recess. The upper cap portion 12 is coupled to a separate base portion 14 which forms the bottom of the socket region 20. The upper cap portion 12 and the base portion 14 are coupled in such a manner so that at least the interface at the bottom of the socket region 20 is water tight.
The sides 30 of the recess of the upper cap portion are additionally shown with two openings 32. Openings 32 are arranged at a height in between the top portion and the bottom of the socket region 20 such that a portion of a conductive wire spring 16 can at least partially extend through the opening 32. The conductive wire spring 16 is for releasably holding the male end of a telemetric device within the socket region of the snap. Additionally, the conductive wire spring 16 make, or at least partially makes, the electrical connection between at least one electrode 24 in a garment or heart rate monitor belt and the male end of a telemetric device.
The conductive wire spring 16 is house at least partially within a gap which is formed between the upper cap portion 12 and the base portion 14. More specifically, according to the present example, the gap is formed between the top portion of the upper cap portion 12 and a portion of the base portion 14. The conductive wire spring 16, according to the present example, is mechanically coupled to the upper cap portion 12 by a lip 34 of the upper cap portion 12. The lip 34 may be within the gap formed between the top portion of the upper cap portion 12 and the base portion 14 or the lip 34 may be located in another region of the snap 10. The conductive wire spring 16 may simply rest on the lip 34, there may be a friction fit between the conductive wire spring 16 and the lip 34 and/or other portion of the upper cap portion 12, there may be an additional mechanical means for holding the conductive wire spring 16, there may be a separate, or additional chemical means, such as an adhesive, for holding the conductive wire spring 16 or there may be some combination of the above. According to certain examples, the wire spring 16 is not rigidly affixed to the upper cap portion 12 but is allowed a small degree of movement due to the mechanical fit of the lip 34 arrangement.
According to certain embodiments, as can be seen for example in
An example of conductive wire springs 16 can be a wire springs with a double ‘S’ shape. The wire spring 16 may have a diameter of between, for example, 0.6 to 0.8 mm. Examples of suitable materials are stainless steels, e.g. AISI 304 or 316. Additionally, the conductive wire spring 16 may be an integral component of either the upper cap portion 12 or the base portion 14.
An example of the conductive wire spring 16 is a double ‘S’ shape which takes the general shape of a horseshoe. In an example in accordance with
The base portion 14 of the snap 10 is shown for example in
According to the present example, the bottom of the recess of the base portion 14 forms the bottom of the socket region 20. However, as described above, at least a portion of the bottom of the socket region 20 may be formed by the upper cap portion 12.
A guiding stud 22 may be provided at the bottom of the socket region. A guiding stud 22 may be added in order to increase the stability of the connection. In the present example the guiding stud 22 is provided on the bottom surface of the recess of the base portion 14. However, the snap of the present example may not have a guiding pin 22 but be otherwise the same as disclosed herein.
The guiding stud 22 acts to center and stabilize the male end of a telemetric device which has a recess compatible with the geometry and dimensions of the guiding stud. In
According to the present example, the guiding stud 22 is an integral portion of the base portion 14. The base portion 14 can be made of a non-conductive material such as a plastic or rubber based material. The guiding stud can be rigid or it may have some, preferably a slight, degree of flexibility. According to certain examples, the guiding stud 22 can be a separate piece which is attached or affixed to the bottom of the socket region. For example, the guiding stud 22 can be a stud or screw which is attached to the bottom of a recess in a base portion during manufacturing. Similarly, if the bottom of the socket region is formed partially or entirely by the upper cap portion 12, the guiding stud may be an integral part, or an additional piece added to the upper cap portion 12. Still yet, the guiding stud may be an integral part, or an additional piece added to a base plate or mat which covers and/or forms the bottom of the socket region. Such a base plate or mat may be, for example a sticker or a piece with an adhesive which is added to the base portion 14 and/or the upper cap portion 12 at the bottom of the socket region 20.
According to certain examples of the present invention the guiding stud 22 can take the geometry of a standard cylinder. Additionally, it can be advantageous for the guiding stud 22 to have a conical geometry, for example as shown in
According to the present examples, the thickest portion of the snap 10 is between the top portion of the upper cap portion 12 and the bottom of the base portion 14 directly underneath the socket region 20. In order to produce a snap which has the least adverse effect on the garment which it is being integrated within, and therefore on the user wearing the garment, it is advantageous to keep this maximum thickness as small as possible. Currently, the standard snap thickness in the industry is around or above 4 mm. With the design of the present snap 10, the maximum thickness of the snap between the top of the upper cap portion 12 and the bottom of the base portion 14 can be between about or even less than 1 to 3 mm or, for example between 1.5 to 2.5 mm. According to certain examples, utilizing the present design can reduce the overall size of the snap portion within a garment by 50-70% or more. This reduction in size is almost solely responsible for the success of integrating heart rate monitors in to garments.
As the snap 10 is, or is to be integrated within a material 18, the overall thickness of the snap 10 can gradually be reduced and/or tapered towards the outer edges, as is seen in the figures. The flange 26 of the upper cap portion 12 is depressed in order to reduce the overall thickness of the snap 10 as well as to allow for better integration with a material layer 18 of a garment. Similarly, as can be seen for example in
As discussed with regards to the embodiments and examples herein, both the upper cap portion 12 and the base portion 14 are generally circular in shape. However, one of ordinary skill in the art will recognize that the geometry of one or both of the upper cap portion 12 and the base portion 14 can be freely selected without departing from the scope of the present invention.
While it is advantageous to minimize the maximum thickness of the snap 10, at the same time it is advantageous to maximize the depth of the socket region of the snap 10 within the overall maximum thickness of the snap 10. According to examples of the present invention the depth of the socket region of the snap between the top of the upper cap portion 12 and the bottom of the socket region is between 1 to 2.5 mm, preferably between 1.5 to 2.5 mm. Similarly, according to examples of the present invention, the depth of the socket region of the snap is between 80 to 98%, preferably between 85 to 97%, still more preferably between 90 to 95% of the maximum thickness of the snap 10.
Within the socket region 20 of the snap 10, according to the present examples and embodiments, it is advantageous for the height of the guiding stud to be at least 0.9 mm from the base of the socket region 20. However, according to certain embodiments and examples, it is advantageous for the height of the guiding stud to be between 0.5 mm to 2 mm, preferably between 0.8 mm to 1.5 mm. Similarly, according to examples of the present invention, the height of the guiding stud is between 20 to 80%, preferably between 30-50% of the depth of the socket region 20.
Additionally, the conductive wire spring 16 can be one of the bulkiest items within the snap. When the conductive wire spring 16 is at least partially housed within a gap created between the upper cap portion 12 and the base portion 14 around the side walls 30 of the socket region 20, it is advantageous to minimize the gap. According to certain embodiments and examples, it is advantageous for the maximum height of the gap to be between 0.5 to 2 mm, preferably between 0.5 to 1 mm.
Although the upper cap portion 12 and base portion 14 are described herein as being separate portions, they may be a single integral piece. However, for manufacturing purposes it is typically advantageous for the upper cap portion 12 and base portion 14 to be separate pieces. According to an example of the present invention, the upper cap portion 12 is a conductive material, e.g. a metal such as stainless steel, and the base portion 14 is a non-conductive material, e.g. a plastic or polymer based material. Similarly, the upper cap portion 12 can be made partially or wholly of a non-conductive material and/or the base portion 14 can be made partially or wholly of a conductive material. As such, it is significantly easier to manufacture the two pieces separately.
When separate pieces, the upper cap portion 12 and the base portion 14 can be coupled in a variety of non-exclusive ways. As discussed above, if the base portion 14 has a recess which corresponds to the recess of the upper cap portion 12, then the upper cap portion 12 and the base portion 14 can be coupled within the recess of the socket region by a mechanical and/or a chemical/adhesive means. Additionally, as shown for example in
A further example of a mechanical connection means 28 is that the base portion 14 comprises a plurality of integral extensions 28 which align with the openings in the upper cap portion 12, and optionally with openings in any electrode and/or other material between the upper cap portion 12 and the base portion 14. The extensions 28 will pass through the openings in the flange 26 and then heat, for example in the form of an ultrasonic or laser application, essentially melts the top portion of the extension such that it forms the cap seen in
In order for a garment to provide the necessary data to a telemetric transmitter, the garment should be provided with at least one, and typically at least two electrodes 24. Several methods for attaching and integrating an electrode 24 with a material 18 are known, for example as presented in U.S. application Ser. No. 11/808,391 filed Jun. 8, 2007 and published as US 2007/0285868 which has been incorporated by reference in its entirety. Additionally, the electrode 24 should make an electrical connection with a stud 38 of a telemetric transmitter through the snap 10.
As such, as can be seen for example in
According to an embodiment of the present invention a snap is manufactured and subsequently integrated within a garment. In such embodiments the snap may be manufactured in one or more pieces which may or may not correspond to the discrete portions described herein. According to another embodiment, the snap is manufactured in a plurality of pieces and is manufactured along with and integral with a garment or heart rate monitor belt.
As described herein, a garment can be any article which is wearable by a human or animal. Examples of garments which are particularly well suited for use with and incorporation with the present example are tops, shirts, sports bras, bras, undergarments, workout apparel, compression sports t-shirts, shorts, bands and belts. With regards to the remainder of the description, heart rate monitor belts and other specialty articles which one of ordinary skill in the art will recognize can implement the description of the present invention and be worn by a human or animal will be encapsulated in the term garment for simplicity. Furthermore, the garments discussed herein may be made of any suitable material including fabrics, cloths, and other such materials of natural or synthetic origin.
A benefit to the present snap is the flush integration of a snap in to a garment such that a garment having a snap in accordance with aspects of the present invention has minimal if any drawback compared to a garment not having a snap, when no measurement is to be taken by the garment.
Examples of heart rate monitor belts using elastomer or rubber electrodes can be found, for example, in WO 2005/032366. Furthermore, examples of textile electrodes can be found, for example, in WO 2002/071935. In addition to monitoring heart rate, the embodiments and examples herein may also be used for EMG monitoring or measurement. Examples of such measurement devices can be found, for example, in WO 2004/002311 and WO 2005/032365. All of the above mentioned references are herein incorporated by reference in their entirety.
According to certain embodiments wherein the snap is an integral portion of a garment and/or the manufacture of the garment, an electrode 24 can be sandwiched between at least the flange 26 of the upper cap portion 12 and at least a portion of the base 14. Additionally, at least one material layer 18 can be disposed on a top portion of the electrode 24 and may, or may not, extend to cover a portion of the flange 26 or even the top portion of the upper cap portion 12. Furthermore, one or more additional material layers 18 may be disposed on at least a portion of a bottom side of the electrode 24 and/or the bottom portion of the base portion 14 in order to more wholly integrate the snap in to the garment.
A non-conductive, preferably water-proof material 64 can be added on top of at least a portion of one or both snaps. As shown in
An example of a telemetric device 50 which is compatible with the garment 60 is shown in
As referenced above, it is advantageous for the side walls 30 of the socket region 20 to correspond with the geometry of the male end of the stud 38 of a telemetric device. As can be seen, for example in
The snap 10 can be arranged at any point and having any orientation with respect to the electrode 24. Additionally, the electrode 24 may take the shape of something other than a strip, as shown in the present example. However, it can be advantageous to integrate the snap 10 at or towards one end of a strip like electrode 24 as shown in
According to the present example, the snap 10 is arranged near a terminal end of the electrode 24. The wire spring 16 is held within the snap 10 by three lips 34. The three lips 34, and consequently the three corresponding notches 35 are arranged in such a way that no notch opens towards the length of the strip electrode 24. This adds a degree of rigidity and support to the assembly.
Additionally, the openings 32 in the side of the socket region 20 of the snap 10 are arranged to be parallel with the length of the electrode 24. In other words, the openings 32 are arranged to be parallel with the sides of the electrode 24 as seen in
According to certain embodiments, when assembling the snap and electrode assembly an upper cap portion 12 can be affixed to an electrode 24 by means of, for example, a conductive tape 29. The conductive tape 29 can be seen in
The flange 26 of the upper cap portion 12 may have one or more openings preformed therein. Similarly, the electrode 24 may have one or more opening preformed therein which correspond to openings in the flange 26 or are otherwise for allowing one or more extensions from the base portion to pass there through. Additionally, one or more openings may be formed through the flange of the upper cap portion 12 and/or electrode 24. The base portion 14 is then affixed to the assembly by extensions 28 which pass through the openings in the electrode and flange 26. The extensions 28 are then deformed, for example by means of an ultrasonic, laser or other heating means, in order to form caps and effectively sandwich the electrode between the upper cap portion 12 and the base portion 14.
The snap 10 of the snap and electrode assembly may be in accordance with any of the examples and embodiments of snaps described herein.
At least a portion of the male head portion is capable of fitting within a socket region of a snap. According to preferred embodiments of the present invention, the male head portion of the stud 38 is configured to fit within a socket region 20 of a snap 10 as described above. As such, at least a portion of the male head portion is disposed outside of the housing 51 of an electronic device. According to certain examples the entire head portion is located outside of the housing 51. Furthermore, according to certain examples, only the head portion is located outside of the housing 51.
In terms of the present disclosure, the male head portion has a terminal end which is the terminal end of the stud 38. The male head portion extends between said terminal end and a second end which separates the male head portion from a mid-portion. The length of the male head portion of the stud 80 is the length between the terminal end and the second end.
According to certain examples, the male head portion comprises a chamfered 40 terminal end which is chamfered from a maximum diameter 82 of the male head portion near the terminal end. The chamfer is added to guide a wire spring snap open, for example to guide the conductive wire springs 16 in the socket region 20 of the snap 10 open as the male head portion is inserted in to the snap. If the chamfers are too small then they are not efficiently capable of guising the male head portion of the stud 38 in to a snap. The amount of chamfer is the difference between the maximum diameter 82 of the male head portion and the diameter 84 at the terminal end of the stud.
Additionally, beyond the maximum diameter 82 of the male head portion, towards the mid-portion, is a concave arced recess. The concave arced recess can be seen, for example, in
Beyond the concave arched recess, towards the mid portion, is the second end of the male head portion. The second end may be an imaginary break between the male head portion and the mid-portion. However, according to certain examples, the second end may have a diameter 96 slightly larger than the end of the concave arched recess, and/or a shim, which can act as a stopper during the screwing process of inserting the stud 38 in to an opening of an electronic device. While in most examples the diameter 96 of the shim and/or second end of the male head portion is less than or equal to the maximum diameter 82 of the male head portion, the diameter 96 of the shim and/or second end of the male head portion may be larger than the maximum diameter 82 of the male head portion.
The end portion 72 of the stud is opposite the male head portion. The end portion has a terminal end which is the second terminal end of the stud, opposite the terminal end of the male head portion of the stud 38. The end portion extends a distance from the second terminal end of the stud to the mid-portion of the stud which is the length 92 of the end portion 72 of the stud 38. The division between the mid-portion of the stud and the end portion may be an imaginary break. However, the division between the mid-portion of the stud and the end portion may be a change in diameter and/or the break between the threaded portion and non-threaded portion at the opposite end of the stud from the male head portion.
According to certain examples, the end portion 72 of the stud is characterized in that it is non-threaded. Additionally, the terminal end of the end portion 72 can be chamfered inwards from the diameter 94 of the end portion 72. The end portion 72 of the stud is for making an electromechancial connection between the stud 38 and a component of the electrical device.
In between the male head portion and the end portion 72 is the mid-portion 88. According to certain examples, the mid-portion is characterized in that it is at least partially threaded. Additionally, according to certain examples the entire mid-portion 88 of the stud is threaded. The threads of the mid-portion 88 are a means of securing the stud 38 in an opening of an electronics device. An example of the threading for the mid-portion is Remform F 2.5 mm.
According to certain examples, the mid-portion 88 of the stud 38 has a constant diameter. Additionally, according to certain examples, the diameter of the mid-portion 88 is less than the diameter 96 at the second end of the male head portion. Furthermore, according to certain examples, the diameter of the mid-portion 88 is greater than the diameter 94 of the end portion 72 of the stud 38.
According to certain embodiments of the present invention, the male head portion has a centered cavity 42 which is open at the terminal end of the male head portion. An example of such a cavity 42 is shown in the cutaway
Additionally, the cavity can be utilized as a recess for a Torx or other tool during the screwing process during manufacturing when the stud 38 is inserted in to an opening of an electronics device. As such, the cavity can have a variety of dimensions and geometries including, for example, a cylindrical cavity, a conical cavity, a TORX PLUS, e.g. 10IP, 8IP or 6IP, geometry, cubic cavity and/or similar geometry or combination of thereof. The cavity may correspond directly to a guiding stud 22 of a snap 10 to which the stud 38 is to be inserted. Additionally, the cavity may have a different geometry which is merely compatible with the geometry of the guiding stud 22. For example, the cavity may have a TORX PLUS IP6 geometry which has a diameter of 1.75 mm and the guiding stud may be cylindrical or conical having a maximum diameter of 1.75 mm or slightly less.
According to certain examples, the depth 86 of the cavity 42 should be at least 0.9 mm. According to other examples, the depth can be between 0.5 to 1.5 mm.
According to one example of a stud in accordance with the present invention, the length 80 of the male portion of the head is 2.1 mm, the maximum width 82 of the male portion of the head is 4.1 mm, the diameter 84 of the terminal end of the male head portion is 3 mm, the depth 86 of the cavity is 1.5 mm, the length of the mid-portion is 5 mm, the length 92 of the end portion is 2 mm, the diameter 96 of the second end of the male head portion is 3.6 mm, the threading of the mid-portion is Remform F 2.5 mm and the diameter 94 of the end portion is 1.5 mm.
More generally, the length 80 of the male portion of the head can be between 1 to 3 mm, the maximum width 82 of the male portion of the head can be between 3.9 to 4.3 mm, the diameter 84 of the terminal end of the male head portion can be between 2.8 to 3.6 mm, the depth 86 of the cavity can be between 0.8 to 1.5 mm, the length of the mid-portion can be between 3 to 5 mm, the length 92 of the end portion can be between 0 to 3 mm, the diameter 96 of the second end of the male head portion can be between 3 to 4 mm and the diameter 94 of the end portion can be between 1 to 2 mm.
Additionally, there is disclosed herein an electronic device 50 having a housing 51 and at least one male connection portion as shown for example in
As shown, for example in
As described above, the stud 38 is threaded and is screwed in to an opening of the housing 51 of an electronic device during manufacturing. During or prior to the stud 38 being inserted and/or screwed in, at least a portion of the threads of the mid-portion of the screw are covered in and/or in contact with an adhesive. An example of an adhesive is Spedcaps Orange. The adhesive not only secures the stud 38 within the housing of the electronics device but it also helps form a water tight barrier between the environment and the electronic component 76.
During manufacturing, an opening can be formed or manufactured in the housing 51 and/or internal cavity of an electronics device 50. The opening can be threaded or unthreaded. In examples where the opening is unthreaded the material can be such that a threading is formed within the opening while the stud 38 is being screwed and/or inserted in to the opening. Additionally, while the present description describes an opening being pre-formed within a housing and/or cavity of an electronics device, one of ordinary skill will recognize embodiments in which a stud 38 can partially or wholly create its own opening in a housing and/or cavity of an electronics device, said embodiments which would not otherwise depart from the scope of the present invention.
At or towards the end of the opening in the electronics device is a component in which the end portion of the stud 38 is to be in electromechanical connection. The component may be an electronics component of the electronics device 50. Additionally, for example in order to account for variations in the manufacturing process, at the end or towards the end of the opening may be a spring contact 70 which the stud is electromechanically connected to once screwed/inserted in to the opening. The spring contact 70 can then be electrically connected to an electronic component 76 such as a printed circuit board. The electric component 76 can be accessible by a cover 74 on top of the electronics device 50.
Additionally, the housing 51 of the electronics device 50 may include a protrusion 68 at the male connection portion. The male head portion of the stud 38 may be partially or entirely outside of the housing and protrusion 68 of the electronics device 50. The protrusion 68 can extend from the second end of the male head portion of the stud, e.g. the shim, at least partially along the mid-portion of the stud 38. The protrusion 68 may extend, for example, between 0 to 2 mm from the base of the electronics device. Additionally, the protrusion 68 may have a diameter greater than the maximum diameter 82 of the male head portion of the stud.
According to an example of a system having an electronics device 50 and at least one snap 10 in accordance with the present description, the snap 10 can have a sealer 64, for example as shown in
Described herein, the electronic device 50 can be a telemetric transmitter and/or telemetric transceiver. Examples of telemetric transmitters and transceivers modules used with heart rate monitor belts to transmit information relating to the heart beat of a user to a remote receiver. One of ordinary skill in the art will recognize countless electronic devices and telemetric devices which can be used within the scope of the present invention. Such electronic devices may or may not comprise a display and may or may not be capable of wirelessly transmitting information. Additionally, they may be capable of sending a wide variety of data not limited to heart rate to a remote receiver.
Furthermore, disclosed herein is a system comprising one or more snaps 10 as described herein in combination with an electronic device having one or more studs 38 as described herein. Such a system can take the form of, for example, a heart rate monitor belt and a telemetric device for transmitting heart rate data from the heart rate monitor belt.
As discussed above, the snaps as described herein are particularly well suited for integration in to garments. However, the spacing between the snaps when integrated in to a garment should be within a small tolerance of the spacing of the telemetric device. While current manufacturers of heart rate monitor belts have the equipment and experience to achieve this degree of installation, the garment industry en mass does not. Therefore, there is provided herein an electrode assembly 120 as shown in
As is shown in
According to certain embodiments, the base portions 14 are made separately and then combined with the non-stretchable material portion 102. In some examples, the base portions 14 are made of a first material and the non-stretchable material portions 102 are made of a second material. The base portions 14 may be premade and then heat molded with the second material to form the linking member 110. The base portion 14 may have one or more portions of its perimeter geometry 104a-c which are complemented by one or more portions of the perimeter geometry 106a-c of the non-stretchable material portion 102. These complementary perimeter geometry portions can help with the chemimechanical bonding in the heat molding. These complementary perimeter geometry portions may also be sufficient to provide a mechanical coupling between the base portions 14 and the non-stretchable material portion 102 on their own. Adhesives or other coupling methods may also be employed. Examples of the non-stretchable material are flexible polymers and plastics as well as non-stretchable technical fabrics.
The linking member 110 can an integral member. The linking member 110 can be formed of a single material. When the linking member 110 is formed of a single material, the material forming the base portions and sections I and III should be of a sufficient rigidity to act as the base portion of the snap. In order to make the non-stretchable material portion flexible, or more flexible, regardless of the composition of the linking member 110, the non-stretchable material portion can have structural elements which reduce its rigidity compared to the first and second base portions. Examples of such structural elements are: slits, gaps in the material, valleys in the material, holes in the material and areas with material of less thickness than other areas.
As described above, the electrode assembly 120 can be a kit and at least one of the following pieces may not be coupled to its respective portion: the first electrode, the upper cap portion of the first electrode, the second electrode, the upper cap portion of the second electrode and the linking member. The base portions may also come separate from the linking member, particularly in embodiments where the base portions are merely mechanically coupled to the non-stretchable material portion. As such, first electrode 24 and the second electrode 24 can be coupled or coupleable to their respective first and second base portions 14 of the linking member 102.
Additionally, the upper cap portions 12 can be located, coupled, coupleable and/or affixed to one side of the electrode 24. Where each upper cap portion 12 has a flange 26 then each flange can comprise a plurality of openings for securing the upper cap portion to the respective electrode and base portion. Each electrode can then have a complementary set of openings and each base portion can have a complementary set of extensions for fitting through the openings in the upper cap portions and the respective electrodes for securing the assembly.
Any of the electrode assemblies 120 discussed above can easily be integrated in to a garment. Electrode assemblies can be integrated in to a garment, for example, by being sewn onto or between a layer of material. Other methods of integration including lamination, being actually built in to the garment or having the material wholly or partially manufactured around the assembly are possible.
When integrated in to a garment, at least a portion of both the first and second electrodes can be arranged such that they are capable of being in direct contact with the skin of a user during normal use of the garment, e.g. on the inside of a garment. Additionally, when integrated in to a garment, at least a portion of each of the upper cap portions can be directly accessible on a side of the garment to be worn away from the wearer such that the snaps are accessible when the garment is being worn. An example of which is shown in
Electrode strips may also have longer conductive path sections. For example, the electrodes 24 can have a first portion which is to be arranged such that it will be against the skin of a wearer and a second portion which is a conductive path portion which is to be isolated from the skin. The electrode 24, or only a portion thereof such as the conductive portion, can be made with a conductive textile material in place of a standard conductive elastomer. These types of constructions can enable longer paths for lower voltage EMG signals.
A garment is essentially anything that can be worn. Examples of such garments are sports shirt, sports bra, technical shirt, underwear, compression garment, heart rate monitor belt, elastic band and athletic pants. The electrode assemblies can be integrated in any portion of the garments. For example, in sports bras the electrode assembly can be located essentially in the middle of the sports bra and can be easily used with a telemetric device for monitoring heart rate information. Another example is in shirts, one electrode assembly can be located near the chest of the garment for monitoring heart rate information and one or more additional electrode assemblies can be located on or near the arms for muscle measurement, e.g. EMG. Similarly, a pair of pants or shorts can have multiple electrode assemblies integrated in areas around muscle groups to be monitored.
