## Background
FIELD OF DISCLOSURE
The present disclosure relates to universal integrated circuit cards, including but not limited to, universal integrated circuit card apparatus and related methods.
BACKGROUND
Electronic devices, including portable electronic devices, have gained widespread use and may provide a variety of functions including, for example, telephonic, electronic messaging, and other personal information manager (PIM) application functions. Portable electronic devices include, for example, several types of mobile stations such as simple cellular telephones, smart telephones, tablet computers, wireless personal digital assistants (PDAs), and laptop computers with wireless 802.11 or Bluetooth capabilities.
Electronic devices such as, for example, portable electronic devices often connect to a network (e.g., a mobile network). These devices often employ a Universal Integrated Circuit Card (hereinafter UICC) to identify a subscriber for network access. For example, the UICC can store a Subscriber Identity Module (e.g., a SIM card, USIM card, RUIM, CSIM, etc.) that authenticates a subscriber to a network such as a mobile network. The UICC may also store other subscriber-related information for non-telecom applications. For example, the UICC can enable contactless data flow for identity, security, banking, payment applications and/or any other application associated with transmitting and securing personal data of a user.

DETAILED DESCRIPTION
Universal integrated circuit cards (UICCs) are often used as a Subscriber Identity Module (e.g., SIM card, USIM card, RUIM card or CSIM card) in a portable electronic device such as a mobile device. A Subscriber Identity Module is a network access application that is stored in the UICC to authenticate a subscriber to a network. In some examples, a UICC enables contactless communication (Near Field Communication) with a host (e.g., a remote terminal) based on proximity of the UICC relative to the host.
Typically, a UICC includes a body to support an integrated circuit or microprocessor and a plurality of electrical contacts to enable communication between the microprocessor and a host (e.g., a computer, a mobile device, a non-mobile device, a remote terminal, etc.). The host typically employs an input device (e.g., a card reader) to accept the body and complete a circuit with the electrical contacts to enable communication (e.g., transfer data) between the UICC and the host.
Currently, physical characteristics or parameters of UICCs are governed by certain international standards provided by, for example, the European Telecommunications Standards Institute (ETSI) and the International Standard Organization (ISO). In particular, physical characteristics or parameters of an UICC are provided by certain form factor standards (e.g., ID-1, plug-in UICC, a mini-UICC) defined by International Standard Organization ISO/IEC 7816-2 and 7816-3 and/or Technical Specification of the European Telecommunications Standards Institute ETSI TS 102 221.
For example, ISO/IEC 7816-2 and/or ETSI TS 102 221 standards define an overall dimensional envelope of conforming UICCs. For example, mini-UICC form factor standards define an overall dimensional envelope of a UICC as 15 millimeters by 12 millimeters, which provides a surface area of 180 millimeters squared. Further, the current standards define a layout of electrical contacts on the UICC as a grid pattern (e.g., 4 by 2 grid pattern) that provides a surface area greater than 1 centimeter squared.
Further, an order or arrangement in which electrical contacts are to be positioned on the UICC is also defined by the standards. For example, the standards specify that a first row of electrical contacts should include a voltage supply, a reset, a clock and an optional first auxiliary, and a second row of electrical contacts should include a ground, a single-wire protocol, an input/output and an optional second auxiliary. However, by providing such an arrangement, the first row of electrical contacts typically pass across electrical contacts of an input device associated with the second row of electrical contacts when the UICC is inserted into the input device, which may cause the circuit card to become electrically damaged (e.g., short circuit). Further, the supply voltage (e.g., the first contact in the first row) is disposed adjacent the ground (e.g., the first contact in the second row), which may increase and/or cause a greater amount of electromagnetic interference (EMI).
While the current specifications ISO/IEC 7816-2 and 7816-3 and ETSI TS 102 221 define standards of a UICC, such standards also influence the design (e.g., the size, shape or footprint) of an input device or card reader, which can also significantly increase a dimensional envelope of a portable electronic device. In some example electronic devices, an input device or card reader covers the greatest amount of surface area of an electronic board of an electronic device (e.g., a mobile phone) compared to other electronic components of the electronic device. For example, by specifying the electrical contacts or pads disposed across an (x) by (y) surface area, an input device having a minimum surface area specified by the (x) by (y) surface area of the electrical contacts is required to properly couple to the electrical contacts of the circuit card. However, smaller electronic devices are generally desirable for portability. As a result, current standards may not be sufficient to reduce the size and/or an overall footprint of a mobile device.
Some known input devices often employ a push-push mechanism to insert/remove a UICC from an input device. A push-push mechanism requires a user to slide the card inside a slot of the input device. To remove the card, a user pushes the card further into the slot and a spring-loaded mechanism ejects the card from the slot. However, push-push card readers often require a door or other holding element to prevent the UICC from sliding out of the card reader (e.g., prevent unintended removal of the card). However, the door and/or holding element may damage easily and/or are relatively more expensive to manufacture.
Another example input device or card reader employs a push-pull configuration. In such example, a UICC is pulled from a slot of the card reader. However, UICCs typically have relatively flat and/or smooth surfaces that make it difficult for the user to grip and pull the card from the card reader. As a result, some example electronic devices employ a tray-style input device or card reader. However, tray-style card-readers typically increase the overall costs and dimensional envelope of an electronic device and/or require a unique tool (e.g., a pin) to remove the tray-style card reader from an electronic device.
In general, example UICCs disclosed herein modify or deviate from the standards provided by ISO/IEC 7816-2 and 7816-3 and/or ETSI TS 102 221 to define another UICC form factor standard. In particular, UICCs disclosed herein provide significantly smaller overall footprints compared to UICCs manufactured per the current specifications and/or standards provided by ISO/IEC 7816-2 and 7816-3 and/or ETSI TS 102 221. In addition, the UICCs disclosed herein also reduce the overall space requirements of an input device or card reader coupled to an electronic device.
In one example, the overall dimensional envelope of the UICC disclosed herein may have a height of between about 10.9 and 11.1 millimeters and a width of between approximately 8.9 and 9.1 millimeters. As a result, a UICC disclosed herein may have a surface area of approximately 99 millimeters squared, thereby significantly reducing the overall dimensional footprint or size of a UICC compared to known UICCs.
In another example, a layout scheme of electrical contacts or electrical pads may differ from a layout provided by, for example, the current ISO/IEC 7816-2 and 7816-3 and/or the ETSI TS 102 221 standards. For example, the electrical contacts disclosed herein may be disposed or coupled to the UICC in a single-row orientation or configuration. As a result, an electronic device may employ a header-style input device or card reader, which uses significantly less surface area of a circuit board (e.g., a logic board) of the electronic device compared to, for example, a multi-dimensional input device (e.g., a multi-row card reader).
Further, unlike known UICC having multi-dimensional electrical contacts, aligning the electrical contacts in a single-row configuration makes the UICC less prone to electrical damage (e.g., short circuit) that may otherwise occur when the circuit card is inserted into an input device as noted above. Additionally or alternatively, in contrast to the current standards provided by ISO/IEC 7816-2 and 7816-3 and/or ETSI TS 102 221, a supply voltage contact and a ground contact of the UICC disclosed herein can be spaced apart from each other to significantly reduce electrical damage (e.g., short circuit) and/or EMI.
Additionally or alternatively, example UICCs disclosed herein may employ a locking mechanism to retain the circuit card in the input device without the use of doors. The locking feature also substantially prevents improper orientation of the circuit card relative to the input device and substantially prevents movement of the circuit card relative to the input device when an electronic device experiences sudden shock or vibration (e.g., if the electronic device is dropped). Also, to facilitate insertion of the circuit card relative to the input device, example UICCs disclosed herein may employ a lead-in feature (e.g., a chamfer). Further, to facilitate removal of the circuit card relative to the input device, example UICCs disclosed herein may employ a pick-out feature (e.g., a ridge, an opening, etc.).
FIG. 1A illustrates an example UICC 100 disclosed herein (hereinafter referred to as “UICC”). FIG. 1B is a side view of the example UICC 100 of FIG. 1A. Referring to FIGS. 1A and 1B, the UICC 100 comprises a body 102 defining a first or front side 104 and a second or rear side 106 opposite the first side 104. The first and second sides 104 and 106 of the illustrated example are spaced apart by a thickness 108 (FIG. 1B). In this example, the thickness 108 is between approximately 0.69 and 0.81 millimeters. Further, in the illustrated example, a height 110 of the body 102 may be between approximately 10.9 millimeters and 11.1 millimeters and a width 112 of the body 102 may be between approximately 8.9 millimeters and 9.1 millimeters. In particular, the height 110 of the body 102 is approximately 11 millimeters and the width 112 of the body 102 is approximately 9 millimeters.
As shown in FIG. 1A, the body 102 of the illustrated example includes a generally rectangular shape defining a first surface 114. More specifically, the first surface 114 has a surface area of approximately 99 millimeters squared. As shown in the illustrated example of FIG. 1A, the first surface 114 of the body 102 is defined by peripheral edges 116. In particular, the first surface 114 is defined by a first edge 118a (e.g., a left edge), a second edge 118b (e.g., an upper edge), a third edge 118c (e.g., a right edge), and a fourth edge 118d (e.g., a bottom edge). The second edge 118b is positioned opposite the fourth edge 118d relative to the body 102 and the first edge 118a is positioned opposite the third edge 118c relative to the body 102. The second and fourth edges 118b and 118d are disposed between the first and third edges 118a and 118c, and the second and fourth edges 118b and 118d are substantially perpendicular to the first and third edges 118a and 118c. As shown, the first and third edges 118a and 118c are substantially parallel relative to each other and the second and fourth edges 118b and 118d are substantially parallel relative to each other.
As shown in FIGS. 1A and 1B, to facilitate insertion of the UICC 100 in an input device or terminal (e.g., a card reader), each of the peripheral edges 116 may include a lead-in feature 120. As shown in FIGS. 1A and 1B, the lead-in feature 120 includes rounded corners each having a radius R1. For example, the radius R1 of the illustrated example may be less than or equal to 0.80 millimeters.
To communicate with a host, the UICC 100 includes an integrated circuit 122 (e.g., an IC). For example, the UICC 100 may include a microprocessor to communicate with a host via, for example, an input device or terminal. To communicatively couple the integrated circuit 122 of the UICC to an electronic device, the UICC of the illustrated example includes a plurality of electrical contacts or contact areas 124. The electrical contacts 124 are disposed on the first surface 114 adjacent the second edge 118b and between the first and third edges 118a and 118c. More specifically, in this example, the electrical contacts 124 are substantially aligned relative to each other in a single row orientation or configuration 126.
In this manner, an electronic device may employ an input device such as, for example, a header-style card reader having a significantly smaller dimensional envelope to significantly reduce an overall dimensional footprint of the electronic device. Additionally or alternatively, providing the electrical contacts 124 in the single row orientation 126 prevents the electrical contacts 124 from passing over other electrical connectors of an input device as the UICC 100 is inserted into the input device, which significantly prevents electrical damage to the UICC 100. However, in other examples, the plurality of electrical contacts 124 may be disposed on the first surface 114 in a staggered pattern, an offset pattern, and/or any other suitable pattern(s). For example, as described below, example UICC apparatus disclosed herein may include multiple rows of electrical contacts 124. In some examples, the electrical contacts 124 may be disposed about a perimeter of the UICC 100 relative to the peripheral edges 116 in, for example, a square pattern, a rectangular pattern, etc.
As shown in FIG. 1A, a classification of the electrical contacts 124 are in accordance with the classification of electrical contacts provided by standards ISO/IEC 7816-2 and 7816-3 and/or ETSI TS 102 221. For example, the electrical contacts 124 of the illustrated example include a supply voltage contact C1, a reset contact C2, a clock contact C3, a first auxiliary contact C4, a ground contact C5, a single-wire protocol contact C6 (e.g., (SWP) for Near-Field Communication (NFC) or proximity transactions), an input/output contact C7, and a second auxiliary contact C8. In some examples, the electrical contacts C4 and C8 can implement a high speed USB interface between the UICC and the host or terminal. The single-wire protocol contact C6 and/or the first and second auxiliary contacts C4 and C8 are optional and may be omitted. In other examples, the UICC 100 may employ any other type of electrical contacts other than those described or represented by electrical contacts C1-C8.
As shown in FIG. 1A, the plurality of contacts 124 are electrically coupled to the integrated circuit 122 via a plurality of wires, traces and/or a bus 128. The integrated circuit 122 may provide a central processor unit (CPU), volatile memory (RAM), non-volatile memory (ROM), etc. The supply voltage contact C1 supplies the integrated circuit 122 with electricity, the ground contact C5 grounds the integrated circuit 122, the reset contact C2 resets the integrated circuit 122, the clock contact C3 provides a clock signal or time reference, and the input/output contact C7 enables performance of data input and output. The optional single-wire protocol contact C6 enables contactless or wireless communication with a remote terminal or host in proximity with the UICC 100. The optional auxiliary contacts C4 and C8 enable the UICC 100 to be coupled to, for example, Universal Serial Bus (USB) interfaces.
In addition to the single row orientation 126 to reduce the overall footprint of an input device and/or significantly reduce the likelihood of electrical damage to the UICC 100, the electrical contacts 124 are arranged on the first surface 114 in a certain order to significantly reduce EMI. For example, the ground contact C5 is spaced apart from the supply voltage contact C1. In other words, at least one other electrical contact C2-C4 and/or C6-C8 (or other electrical contacts) is disposed between the ground contact C5 and the supply voltage contact C1. As shown in FIG. 1A, the ground contact C5 is disposed adjacent the first edge 118a and the supply voltage contact C1 is disposed adjacent the third edge 118c. More specifically, in the illustrated example, the ground contact C5 is spaced from the supply voltage contact C1 by a maximum distance. Further, the clock contact C3, which has the highest frequency, is disposed adjacent the ground contact C5. In this manner, separating the supply voltage contact C1 and the ground contact C5 and/or positioning the clock contact C3 adjacent the ground contact C5 significantly reduces EMI.
Further, in the illustrated example, the second auxiliary contact C8 is positioned adjacent the clock contact C3, the input/output contact C7 is positioned adjacent the second auxiliary contact C8, the single wire protocol contact C6 is positioned adjacent the second auxiliary contact C8, the first auxiliary contact C4 is positioned adjacent the single-wire protocol contact C6, and the reset contact C2 is positioned adjacent the first auxiliary contact C4. Additionally or alternatively, the positions of each of the electrical contacts C1-C8 comply and/or are within the specification or standards provided by ISO/IEC 7816-2 and 7816-3 and/or the ETSI TS 102 221. For example, the following table illustrates the distance of the respective electronic contacts relative to the first edge 118a as shown in FIG. 1A.

For example, the ground contact C5 is positioned at a distance D1 of approximately 0.3 millimeters from the first edge 118a, the clock contact C3 is positioned at a distance D2 of approximately 1.4 millimeters from first edge 118a, the second auxiliary contact C8 is positioned at a distance D3 of approximately 2.5 millimeters from the first edge 118a, the single-wire protocol contact C6 is positioned at a distance D4 of approximately 3.6 millimeters from the first edge 118a, the input/output contact C7 is positioned at a distance D5 of approximately 4.7 millimeters from the first edge 118a, the first auxiliary contact C4 is positioned at a distance D6 of approximately 5.8 millimeters from the first edge 118a, the reset contact C2 is positioned at a distance D7 of approximately 6.9 millimeters from the first edge 118a, and the supply voltage contact C1 is positioned at a distance D8 of approximately 8.0 millimeters from the first edge 118a. 
Each of the electrical contacts 124 of the illustrated example has a rectangular shape. As shown in FIG. 1A, each of the electrical contacts 124 has a width W1 and a height H1. In this example, the width W1 is approximately 0.7 millimeters and the height H1 is approximately 3.0 millimeters. However, in other examples, each of the electrical contacts 124 may have a different sized height H1, width W1 and/or may have a square shape, rounded corners and/or any other suitable shape or configuration or any combination thereof. In addition, the electrical contacts 124 are equally spaced apart by a distance W2. In the illustrated example, the distance W2 is approximately 0.40 millimeters. Further, both the ground contact C5 and the supply voltage contact C1 are spaced from the respective first and third edges 118a and 118c by a distance of approximately 0.3 millimeters.
Although not shown, in other examples, the electrical contacts 124 illustrated in FIG. 1A can be disposed in any order. For example, the electrical contacts 124 may be disposed sequentially C1-C8 and/or in any other suitable order. In some examples, the first auxiliary input C4 may be disposed adjacent the first edge 118a of the body 102 instead of the ground contact C5 and/or the second auxiliary input C8 may be disposed adjacent the third edge 118c. In this example, the overall width 112 of the UICC 100 can be further reduced in examples in which the auxiliary contacts C4 and C8 are omitted. Additionally or alternatively, the electrical contacts 124 may include different contacts other than the electrical contacts associated with the classifications C1-C8 as described in FIG. 1A. Further, in some examples, any one of the electrical contacts C1-C8 may be omitted or replaced with another electrical contact.
To prevent a metal housing portion of an input device from electrically damaging (e.g., shorting) the electrical contacts 124 when the UICC 100 is inserted into the input device, the example UICC 100 includes a buffer area 130 between the second edge 118b and an upper edge 132 of each of the electrical contacts 124. In other words, the electrical contacts 124 are offset relative to the second edge 118b by an offset distance V1. For example, the offset distance V1 may be between approximately 0.1 millimeters and 0.50 millimeters. Further, in this example, the rounded corners of the body 102 help maintain a substantially consistent or relatively even buffer area 130 adjacent the corners of the body 102.
To facilitate handling and/or insertion/removal of the UICC 100 from an input device or card reader, the UICC 100 of the illustrated example employs a grip or pick-out feature 134. In this example, the pick-out feature 134 is disposed adjacent the fourth edge 118d between the first and third edges 118a and 118c. As shown in FIG. 1A, the pick-out feature 134 is a slot or opening. The slot shown in FIG. 1A is defined by a rectangular portion 136 disposed between first and second arcuate or circular ends 136a and 136b. A first portion of the rectangular portion is positioned at a distance V4 relative to the second edge 118b and a second portion of the rectangular portion 136 is positioned at a distance V5 from the second edge 118b. In this example, the distance V4 may be between approximately 9.69 and 9.71 millimeters and the distance V5 may be between approximately 10.39 and 10.41 millimeters such that the slot defines an opening sized between approximately 0.68 and 0.72 millimeters. In other examples, the pick-out feature 134 may be omitted.
Additionally, a first center 138a of the first arcuate end 136a is positioned at a distance P1 from the first edge 118a and a second center 138b of the second arcuate end 136b is positioned at a distance P2 from the first edge 118a. In the illustrated example, the first distance P1 is between approximately 1.9 and 2.1 millimeters and the second distance P2 is between approximately 6.9 and 7.1 millimeters from the first edge 118a. In other examples, the pick-out feature 134 may be a slot having an opening that is recessed in the first surface 114. In other words, a slot forms a recessed opening that does not pass through the entire thickness 108 of the body 102. In other examples, the pick-out feature 134 may be a raised lip portion, an aperture and/or any other surface or feature to enable or facilitate handling the UICC 100.
To secure the UICC 100 in a cavity of an input device, the example UICC 100 includes a notch or locking feature 140. More specifically, the notch 140 retains the UICC 100 within an input device and prevents the UICC from moving (e.g., bouncing) or dislodging from the input device when, for example, the electronic device experiences a sudden shock (e.g., the device is dropped). Additionally or alternatively, the notch 140 significantly reduces or prevents misalignment and facilitates proper orientation of the UICC 100 relative to the input device when the UICC 100 is coupled to the input device as described in greater detail below in connection with FIG. 3A.
The notch 140 of the illustrated example is disposed along the third edge 118c of the body 102. In particular, the notch 140 forms a recessed edge 142 spaced away from the third edge 118c and toward the first edge 118a. As shown in the example of FIG. 1A, the recessed edge 142 is positioned at a distance of P3 relative to the first edge 118a. In this example, the distance P3 is between approximately 8.29 and 8.31 millimeters. The notch 140 of the illustrated example forms a recessed opening 144 having a shoulder or catch feature 146 between a first portion 148a of the third edge 118c and a first end 142a of the recessed edge 142 and a substantially tapered edge 150 between a second portion 148b of the third edge 118c and a second end 142b of the recessed edge 142. The shoulder 146 is substantially parallel relative to the second edge 118b and substantially perpendicular relative to the first portion 148a of the third edge 118c. 
Additionally, the shoulder 146 is positioned at a distance V2 from the second edge 118b of the body 102. In this example, the distance V2 is between approximately 4.49 and 4.51 millimeters. Also, the tapered edge 150 intersects the second portion 148b of the third edge 118c at a position V3 relative to the second edge 118b of the body 102. In this example, the distance V3 is between approximately 6.68 and 6.7 millimeters. Further, the example body 102 includes a radius R2 between the shoulder 146 and the recessed edge 142 and a radius R3 between the tapered edge 150 and the recessed edge 142. In this example, the radius R2 is less than or equal to 0.3 millimeters and the radius R3 is less than or equal to 0.7 millimeters. In other examples, the notch 140 may be omitted. In other examples, the notch 140 may have any other shape or profile such as described in FIGS. 11 and 12.
The example UICC 100 of FIGS. 1A and 1B may be formed via, for example, a punch-out flat sheet manufacturing process(es). The body 102 may be composed of, for example, a plastic material and the pick-out feature 134 and/or the notch 140 are formed via, for example, a punching process(es). The electrical contacts 124 may comprise a unitary sheet composed of electrically conductive material (e.g., copper, etc.) having divided contacts C1-C8 that may be coupled to the first surface 114 of the body 102 via, for example, glue, solder, or any other suitable fastener(s). The integrated circuit 122 may be positioned or coupled to the body via, for example, a pick and place robot or other manufacturing equipment. For example, the integrated circuit may be soldered onto the first surface 114 of the body 102. The wires or traces 128 may be coupled to the body 102 via wire bonding manufacturing techniques or process(es).
Alternatively, as described in greater detail below, the body 102 of the example UICC 100 may be composed of a plastic material formed via, for example, injection molding. In this manner, the body 102 and/or the UICC 100 can be manufactured with more precise tolerances (e.g., relatively tighter tolerances) compared to the flat sheet manufacturing process as described above. For example, the UICC 100 can be manufactured such that the dimensions D1-D8, P1-P3, V1-V5, R1-R3, H1, W1, W2, the height 110 and/or the width 112 can be within a tolerance value of approximately 0.1 millimeters.
FIG. 2A illustrates the example UICC 100 of FIGS. 1A and 1B being inserted in an example input device or card reader 200 in a first orientation 202. Generally, the input device 200 enables communication between the UICC 100 and a host such as, for example, a computer, a point of sale terminal, a remote terminal, a mobile device, etc. In addition, the input device 200 provides power to the UICC 100 or the integrated circuit 122 and also performs protocol conversation and/or reformats data for use by the UICC 100.
In particular, the UICC 100 is inserted in an opening or cavity 204 of the input device 200 with a leading edge 206 (e.g., the second edge 118b) of the body 102 oriented in a direction represented by arrow 208. Further, due to the single row configuration 126 of the electrical contacts 124, the electrical contacts 124 do not pass over or across other electrical contacts or connectors of the input device 200 when the UICC 100 is inserted in the opening 204. Additionally or alternatively, the supply voltage contact C1 is adjacent the third edge 118c and electrically couples to the input device 200 only when the UICC 100 is fully inserted in the opening 204. In other words, the electrical contacts 124 simultaneously engage their respective electrical contacts (e.g., not shown) of the input device 200 when the UICC 100 is inserted in the input device 200. Thus, the UICC 100 receives power only after the UICC 100 is fully inserted and properly oriented relative to the opening 204 of the input device 200. Such a configuration prevents electrical damage to the electrical contacts 124, the UICC 100 and/or the input device 200. In addition, placement of the clock electrical contact C3, which has the highest frequency, adjacent the ground electrical contact C5 significantly reduces EMI.
Further, when the UICC 100 is inserted into the input device 200, the notch 140 can engage a lock or catch feature 210 of the input device 200 to secure the UICC 100 in the opening 204 of the input device 200. As a result, the UICC 100 remains secured within the input device 200. To remove the UICC 100 from the input device 100, the UICC 100 is moved in the direction of arrow 208 when the UICC 100 is in the opening 204 such that the tapered surface 150 releases the lock or catch feature 210 from the shoulder 142 of the notch 140 (e.g., the tapered surface 150 biases the catch feature 210 away from the notch 140). A spring-loaded ejection mechanism (not shown) can then eject the UICC 100 from the opening 204 and the pick-out feature 134 enables a user to firmly grasp the UICC 100 and pull it away from the opening 204 in a direction opposite of the direction indicated by the arrow 208.
Further, providing the height 110 with a dimensional value that is different than the dimensional value of the width 112 significantly prevents erroneous insertion into the opening 204 of the input device 200.
FIG. 2B illustrates the example UICC 100 of FIGS. 1A and 1B being inserted in another example input device or card reader 201 in the first orientation 202. In contrast with the input device 200 of FIG. 2A, the example input device 201 of FIG. 2B does not include the locking feature 210 as shown in FIG. 2A. Nonetheless, the UICC 100 properly fits within an opening 205 of the input device 201.
FIG. 3A illustrates the example UICC 100 of FIGS. 1A and 1B being inserted in another example input device or card reader 300 in a second orientation 302. Unlike the example of FIG. 2A, the UICC 100 shown in FIG. 3A is inserted in an opening 304 of the input device 300 with the third edge 118c of the body 102 as a leading edge 306 oriented in a direction represented by arrow 308. As noted above, the orientation of the electrical contacts 124 as shown in FIGS. 1A and 1B prevent electrical damage when the UICC 100 is inserted into the input device 300. Further, in this example, because the supply voltage contact C1 is adjacent the third edge 118c or the leading edge 306, the supply voltage contact C1 is the last electrical contact 124 to couple to a respective electrical contact or connector (not shown) of the input device 300 and does not drag the other electrical contacts 124 across power. As a result, the UICC 100 is not powered during insertion of the UICC 100 into the input device 300, thereby significantly reducing potential short circuits and/or electrical damage to the UICC 100. The UICC 100 receives power only after the UICC 100 is fully inserted into the opening 204 of the input device 300.
Additionally or alternatively, the notch 140 as shown in FIG. 3A facilitates or enables proper orientation of the UICC 100 relative to the opening 304 of the input device 300. More specifically, when the UICC 100 is properly oriented relative the input device 300, a guide feature 310 (e.g., a protrusion) of the input device 300 nests within the recessed opening 144 formed or defined by the notch 140. In this manner, the UICC 100 can only be properly inserted within the opening 304 of the input device 300 when the leading edge 306 of the UICC 100 is inserted within the opening 304 and the second edge 118b of the UICC 100 is adjacent a first side 312 of the input device 300. For example, the UICC 100 may not properly fit within the opening 304 if the second edge 118b is adjacent a second side 314 of the input device 300 even if the leading edge 306 is properly oriented relative to the opening 304 due to interference between the guide feature 310 and the edge 118c adjacent the notch 140. Likewise, if the UICC 300 is inserted in the input device 300 with the first edge 118a as the leading edge, the guide feature 310 interferes with the first edge 118a to prevent the UICC 300 from properly fitting within the opening 304. In some examples, the UICC 100 properly fits within the opening 304 when the first edge 118a of the UICC 100 substantially aligns with an end 316 of the opening 304 and/or the input device 300. For example, improper orientation may cause the first edge 118a of the UICC 100 to project away from the opening 304 relative to the end 316.
FIG. 3B illustrates the example UICC 100 of FIGS. 1A and 1B being inserted in another example input device or card reader 301 in the second orientation 302. In contrast with the input device 300 of FIG. 3A, the example input device 301 of FIG. 3B does not include the guide feature 310 shown in FIG. 3A. Nonetheless, the UICC 100 properly fits within an opening 303 of the input device 301.
FIG. 4A is a plan view of another example UICC 400 disclosed herein. The example UICC 400 of FIG. 4A includes a body 402 defining a first side or surface 404 and a second surface or surface 406 opposite the first surface 404. The first and second surfaces 404 and 406 of the illustrated example are spaced apart to define a body thickness 408. To facilitate insertion of the UICC 400 into an input device or card reader, the example UICC 400 of FIG. 4A employs a lead-in feature 410. As shown in FIG. 4A, the lead-in feature 410 is disposed on a leading end 412 of the UICC 400. Additionally, in the illustrated example, each of the first and second surfaces 404 and 406 includes the lead-in feature 410. However, in other examples, only the first surface 404 or the second surface 406 includes the lead-in feature 410. As most clearly shown in FIG. 4B, the lead-in feature 410 of the illustrated example includes tapered edges 414a and 414b adjacent the leading edge 412. In other examples the lead-in feature 410 may be chamfered edges, angled edges, rounded edges, or any other shaped-edge to facilitate insertion of the UICC 400 in an input device such as the input device 200 of FIG. 2. The lead-in feature 410 may be formed via secondary manufacturing process(es) such as, for example, machining (e.g., chamfer milling) and/or other suitable manufacturing process(es). In some examples, the lead-in feature 410 may be formed via injection molding to eliminate a secondary manufacturing process as described in greater detail below in connection with FIG. 9A, FIG. 9B and FIG. 9C.
FIG. 5 illustrates another example UICC 500 disclosed herein. The UICC 500 of FIG. 5 is implemented with a plurality of electrical contacts 502 (e.g., six electrical contacts). In the illustrated example, the electrical contacts 502 may include, for example, the ground contact C5, the clock contact C3, the single-wire protocol contact C6, the input/output contact C7, the reset contact C2 and the supply voltage contact C1. For example, the first and second auxiliary electrical contacts C4 and C8 of FIGS. 1A and 1B may be omitted. In other examples, the UICC 500 may include only one of the auxiliary electrical contacts C4 or C8 of FIG. 1A.
FIG. 6A illustrates another example UICC 600 disclosed herein. FIG. 6B is a side view of another example UICC 600 disclosed herein. Referring to FIGS. 6A and 6B, the UICC 600 of FIG. 6A and FIG. 6B is a dual-sided UICC. The UICC 600 of FIG. 6A includes a body 602 defining a first side or surface 604 (FIG. 6B) and a second side or surface 606 opposite the first surface 604. In particular, the first surface 604 of the UICC 600 includes one or more electrical contacts 608 and the second surface 606 of the UICC 600 includes one or more electrical contacts 610. For example, the electrical contacts 608 disposed on the first surface 604 of the UICC 600 may include the electrical contacts C1-C3, C5-C7 as shown, for example, in FIG. 5, and the electrical contacts 610 disposed on the second surface 606 may include, for example, the first and second auxiliary contacts C4 and C8 of FIG. 1A. A dual-sided header-style input device or card reader may be employed to communicatively couple the electrical contacts on both surfaces 604 and 606 of the UICC 600 to a host (e.g., an electrical device).
FIG. 7 illustrates another example UICC 700 disclosed herein. As shown in FIG. 7, the UICC 700 includes a body 702 defining a first side or surface 704 that includes a plurality of electrical contacts 706. In particular, as shown in FIG. 7, an electrical contact 708 of the plurality of electrical contacts 706 has a different size and/or shape than the other ones of the electrical contacts 710. More specifically, the electrical contact 708 expands or covers a greater surface area 712 of the first surface 704 relative to the other electrical contacts 710. For example, as shown, the electrical contact 708 may be a ground electrical contact C5. Increasing a surface area of the ground electrical contact C5 may significantly reduce EMI.
FIG. 8 illustrates another example UICC 800 disclosed herein. More specifically, the UICC 800 of FIG. 8 illustrates another example electrical contact configuration 802 expanding across a surface area 804 of a first side or surface 806 of a body 808 of the UICC 800. As shown, the UICC 800 includes a first plurality of electrical contacts 810 and a second plurality of electrical contacts 812. In particular, the first plurality of electrical contacts 810 are interconnected or electrically coupled via a coupling portion 814 to cover a greater amount of the surface area 804 of the first surface 806 than for example the electrical contacts 810 or the electrical contacts 124 of FIG. 1A. For example, the first plurality of electrical contacts 810 and the coupling portion 814 may be the ground electrical contact C5. As noted above, configuring the ground contact C5 to cover or expand across a greater amount of surface area on the first surface 806 may significantly reduce EMI. In other examples, an electrical contact and/or the coupling portion 814 may span across substantially the entire surface area 804 of the first surface 806 between peripheral edges 816a-d of the UICC 800.
FIG. 9A illustrates a perspective view of another example UICC 900 disclosed herein. FIG. 9B is a plan view of the example UICC 900 of FIG. 9B. FIG. 9C is an exploded view of the example UICC 900 of FIGS. 9B and 9C.
The UICC 900 of FIGS. 9A-9C includes a body 902 defining a first side or surface 904 and a second side or surface 906 opposite the first surface 904. In the illustrated example, the body 902 or the first surface 904 is approximately 9 millimeters by 11 millimeters and defines a surface area 904a of approximately 99 millimeters squared. The body 902 of the illustrated example is composed of a plastic material (e.g., a Laser Direct Structuring (LDS) resin) and is formed via, for example, injection molding. As shown, because the body 902 may be formed via injection molding, the example body 902 may include a recessed cavity 912 to receive an integrated circuit or microprocessor 914. Also, forming the body 902 via, for example, injection molding enables the body 902 to be formed with relatively more precise and/or tighter tolerances compared to other manufacturing process(es) such as, the flat sheet manufacturing process(es) described above. In addition, forming the body 902 via injection molding provides a relatively smoother surface finish to the first surface 904 and/or the second surface 906 and provides relatively smoother corners 908a-d or edges 910a-d compared to other manufacturing process(es) such as the flat-sheet manufacturing process. Providing relatively smoother surface finishes, corners and/or edges facilitates insertion and/or an interaction between the UICC 900 and an input device or card reader.
In the illustrated example, after the body 902 is formed via an injection molding process, one or more electrical contacts 916 and/or one or more electrical traces or connectors 918 electrically coupling the electrical contacts 916 to the integrated circuit 914 may be formed or etched in the body 902 via, for example, LDS manufacturing process. Such a process enables injection molded plastic parts to be selectively plated with discrete circuit pathways (i.e., the traces 918). To this end, a laser basically etches, writes or prints a conductive pattern corresponding to the position of the electrical contacts 916 and/or the electrical connectors 918 onto the first surface 904 of the body 902 after the body 902 is formed via injection molding. The body 902 is then immersed within a copper bath to provide the conductive electrical contacts 916 and/or traces 918. For example, the electrical contacts 916 may include the electrical contacts C1-C8 described in FIG. 1A and may include the electrical contact orientation or layout provided by the example UICC 100 of FIG. 1A.
The integrated circuit or microprocessor 914 may then be disposed in the cavity 912 of the body 902 via, for example, a pick and place robot and the integrated circuit or microprocessor 914 may be coupled to the body 902 via, for example, soldering. A cover or screen 920 such as a laminate cover may be coupled to the body 902 and disposed over the integrated circuit 914 to protect the integrated circuit from debris and/or other contaminates.
To facilitate insertion in an input device, the example UICC 900 of the illustrated example includes a lead-in feature 922 adjacent a leading edge 924. In this example, the lead-in feature 922 may be the rounded corners 908b and 908c and/or may include an arcuate or curved shaped profile. In other examples, the lead-in feature 922 may be a tapered or chamfered edge adjacent the leading edge 924 such as, for example, the tapered or chamfered edge 410 illustrated in FIG. 4A. The lead-in feature 922 may be formed during the injection molding process. Thus, unlike the flat-sheet punch out manufacturing process, the example lead-in feature 922 may be formed with the body 902, thereby eliminating secondary manufacturing process(es) and/or significantly reducing costs.
The example UICC of FIGS. 9A-9C also includes a pick-out feature 926 to facilitate removal of the UICC 900 from an input device. In the illustrated example, the pick-out feature 926 comprises a raised lip or molded ridge 928 protruding away from the first surface 904 adjacent the edge 910d of the first surface 904. As shown in FIGS. 9A-9C, the raised lip 928 has an arcuate profile, edge or shape. In other examples, the second surface 906 opposite the first surface 904 may also include a raised lip or molded ridge (e.g., similar to the raised lip 928) protruding away from the second surface 906. In some examples, the raised lip or molded ridge 928 may be disposed on the second surface 906 instead of the first surface 904.
The body 902 of the illustrated example also includes a notch 930. The notch 930 is formed on the edge 910c of the body 902 between the electrical contacts 916 and the raised lip 928 and provides a catch or locking feature similar to the locking feature described in connection with FIGS. 1A and 1B.
FIG. 10A is a perspective view of another example UICC 1000 disclosed herein. FIG. 10B is a plan view of the example UICC 1000 of FIG. 10A. Referring to FIGS. 10A and 10B, the UICC 1000 comprises a body 1002 defining a first or front surface or side 1004 and a second or rear surface or side 1006 opposite the first surface 1004. The body 1002 of the illustrated example includes a plurality of electrical contacts 1008 positioned or arranged in a plurality of rows 1008a and 1008b. For example, a first row 1008a of electrical contacts 1008 may include the supply voltage contact C1 adjacent a first edge 1010, the reset contact C2 adjacent the supply voltage contact C1, the clock contact C3 adjacent the reset contact C2, and the first auxiliary contact C4 adjacent the clock contact C3 and/or a second edge 1012. Additionally, a second row 1008b of electrical contacts 1008 may include the ground contact C5 adjacent the first edge 1010 and below the supply voltage contact C1, the single-wire protocol contact C6 adjacent the ground contact C5, the input/output contact C7 adjacent the single-wire protocol contact C6, and the second auxiliary contact C8 adjacent the input/output contact C7.
In the illustrated example, the supply voltage contact C1 and the ground contact C5 may be disposed a distance of approximately 0.45 millimeters from the first edge 1010, the reset contact C2 and the single-wire protocol electrical contact C6 may be disposed a distance of approximately 2.65 millimeters from the first edge 1010, the clock contact C3 and the input/output contact C7 may be disposed a distance of approximately 4.85 millimeters from the first edge 1010, and the first and second auxiliary contacts C4 and C8 may be positioned at a distance of approximately 7.05 millimeters from the first edge 1010.
In addition, the first row 1008a of electrical contacts 1008 may be positioned at a distance of approximately 0.5 millimeters from a third edge 1014 and the second row 1008b of electrical contacts 1008 may be positioned at a distance of approximately 5.80 millimeters from the third edge 1014. A spacing or area S1 between each of the electrical contacts 1008 may be, for example, 0.75 millimeters. The supply voltage contact C1 and the ground contact C5 may be positioned from the first edge 1010 at a distance of approximately 0.45 millimeters and the each of the first and second auxiliary contacts C4 and C8 may be positioned from the second edge 1012 at a distance of approximately 0.45 millimeters.
Each of the electrical contacts 1008 of the illustrated example has a substantially square shape or profile. As shown in FIG. 10B, a width W1 of each of the electrical contacts 1008 is approximately 1.5 millimeters and a height H1 of each of the electrical contacts 1008 is approximately 1.5 millimeters. However, in other examples, each of the electrical contacts 1008 may have a rectangular shape and/or any other suitable shape or configuration and/or a combination thereof.
Each of the electrical contacts 1008 is electrically coupled to an integrated circuit or microprocessor 1018 via respective traces or wires 1020. The electrical contacts 1008 may be coupled to the body 1002 (e.g., via a glue, solder, etc.) and the traces or wires 1020 may be coupled to the body 1002 via, for example, wire bonding manufacturing process. In other examples, the body 1002 may be formed via injection molding and the electrical contacts 1008 and/or the traces or wires 1020 may be formed on the body 1002 via, for example, LDS manufacturing process.
The example UICC 1000 of the illustrated example also includes a pick-out feature 1022. In the illustrated example, the pick-out feature 1022 is an aperture or hole 1024 disposed adjacent a fourth edge 1026. In particular, the aperture 1024 is formed adjacent a corner 1028 defined by the first edge 1010 and the fourth edge 1026. However, in other examples, the pick-out feature 1022 may be disposed between the first and third edges 1010 and 1014 or adjacent a corner formed by the third 1014 and a fourth edge 1026.
The example UICC 1000 of the illustrated example also employs a notch 1030 to secure the UICC 100 in a card reader. As shown, the notch 1030 is formed along the third edge 1014 between the second row of electrical contacts 1008b and the fourth edge 1026. Because the UICC 1000 includes the first and second rows 1008a and 1008b of electrical contacts 1008 disposed over a greater amount of surface area of the first surface 1004 of the body 1002, the notch 1030 is formed adjacent the fourth edge 1026. The notch 1030 includes a shoulder 1032 to provide a stop or engage a catch feature of an input device and a tapered surface 1034 to release the catch feature when the UICC 1000 is removed from the input device. The input device may be a card reader such as a two-row, header-style card reader. Additionally, to protect the electrical contacts 1008 and/or the integrated circuit 1018 from contaminates and/or to provide electrical insulation, the UICC 100 may include a cover or laminate 1036. The cover 1036 of the illustrated example is coupled to the first surface 1004 and disposed over the electrical contacts 1024 and the integrated circuit 1018.
FIG. 11 illustrates another example UICC 1100 having another example locking feature or notch 1102 described herein. In this example, the notch 1102 has a substantially arcuate profile or shape 1104 forming a cavity 1106 to engage, accept, release and/or interact with a locking mechanism (e.g. a biasing element or spring) of an input device. In particular, the arcuate profile 1104 of the illustrated example has a semi-circular or circular shape or profile 1108. In another example, the arcuate shape 1104 may have an oval shape, an elliptical shape, and/or may employ any other suitable shape or profile to engage a locking mechanism of, for example, an input device.
FIG. 12 illustrates another example UICC 1200 having another example locking feature or notch 1202 described herein. In this example, the notch 1202 has a substantially arcuate profile or shape 1204 forming a cavity 1206 to engage, accept, release and/or interact with a locking mechanism (e.g. a biasing element or spring) of an input device. In particular, the arcuate profile 1204 of the illustrated example has an oval or elliptical profile 1208. In another example, the arcuate shape 1204 may have a circular shape or profile and/or may employ any other suitable shape or profile to engage a locking mechanism of, for example, an input device.
The present disclosure may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the disclosure is, therefore, indicated by the appended claims rather than by the foregoing description. All changes that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
