## Background
BACKGROUND
As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.
Near field communication (NFC) is a form of short-range wireless communication where an antenna that is smaller than a wavelength of the carrier signal may be used to transmit the carrier signal. In the near-field (approximately one quarter of a wavelength), the antenna may produce an electric field, a magnetic field, etc. However, some forms of NFC may require that the transmitter and receiver be (i) in close proximity (e.g., 10 mm or less), (ii) within a line of sight, or both. Such usage restrictions may limit the applications in which NFC can be used.

DETAILED DESCRIPTION
For purposes of this disclosure, an information handling system may include any instrumentality or aggregate of instrumentalities operable to compute, calculate, determine, classify, process, transmit, receive, retrieve, originate, switch, store, display, communicate, manifest, detect, record, reproduce, handle, or utilize any form of information, intelligence, or data for business, scientific, control, or other purposes. For example, an information handling system may be a personal computer (e.g., desktop or laptop), tablet computer, mobile device (e.g., personal digital assistant (PDA) or smart phone), server (e.g., blade server or rack server), a network storage device, or any other suitable device and may vary in size, shape, performance, functionality, and price. The information handling system may include random access memory (RAM), one or more processing resources such as a central processing unit (CPU) or hardware or software control logic, ROM, and/or other types of nonvolatile memory. Additional components of the information handling system may include one or more disk drives, one or more network ports for communicating with external devices as well as various input and output (I/O) devices, such as a keyboard, a mouse, touchscreen and/or video display. The information handling system may also include one or more buses operable to transmit communications between the various hardware components.
As computing devices, such as tablets, notebooks, wireless phones, and the like continue to proliferate, many of these devices may be designed using two or more components. For example, a computing device, such as a “2-in-1” computing device, may include two components, such as a head and a base. The head component may include a touchscreen display device and may be independently usable as a computing device, such as a tablet computer or a wireless phone. In addition, attaching the head to the base may enable the head to access resources that are included in the base, such as one or more input devices (e.g., keyboard, touch pad, keypad, etc.), one or more storage devices (e.g., random access memory (RAM), read only memory (ROM), other types of memory, disk drives, other types of storage devices, etc.), one or more ports (e.g., a universal serial bus (USB) port, a serial port, a digital video interface (DVI) port, a high definition multimedia interface (HDMI) port, a card reader (e.g., for reading a compact flash card, a secure digital (SD) card, etc.), another type of resource, or any combination thereof. In this way, the 2-in-1 computing device may be used as two devices, e.g., either as a first type of computing device (e.g., such as a tablet, when using just the head) or as a second type of computing device (e.g., such as a laptop, when the head is coupled to the base).
In a conventional 2-in-1 computing device, the head may be electrically coupled to the base using electrical contacts that enable the head and base to communicate with each other (e.g., to enable the head to access the resources of the base, etc.). However, having exposed electrical contacts on the head and the base may result in the electrical contacts becoming corroded, dirty, worn, damaged, or any combination thereof. Therefore, a 2-in-1 computing device that uses near field communication (NFC) to enable the head to communicate with the base may avoid problems caused by the electrical contacts becoming corroded, dirty, worn, damaged, etc.
A 2-in-1 computing device may be designed such that when the head is coupled to the base, the head may rotate relative to the base. For example, the head of the 2-in-1 computing device may rotate relative to the base to enable a user to position the screen at a particular viewing angle, similar to the way the user may position a screen of a laptop. When NFC is used to enable communications between the head and the base, a first transmitter/receiver (referred to hereinafter as a “transceiver”) may be included in the head and a second transceiver may be included in the base. The NFC may work when the first transceiver and the second transceiver are (i) in close proximity (e.g., 10 mm or less) and (ii) within a line of sight but may not work if they are greater than 10 mm apart or not within a line of sight.
To enable NFC-based communications between a head and a base in a 2-in-1 computing device where the head is capable of rotating relative to the base, one or more waveguides may be used to receive a transmission from a transmitter (e.g., a first transceiver) and provide (e.g., transmit) the transmission to a receiver (e.g., a second transceiver). A waveguide is a structure that guides waves, such as electromagnetic waves, from the first transceiver to the second transceiver. For example, the waveguide may vibrate in response to receiving a signal (e.g., carrier signal) from a transmitter and transmit the vibrations to a receiver. The waveguide may be made from a material such as plastic, metal, glass, wood, another type of material, or any combination thereof.
Thus, one or more transceivers and one or more waveguides may be used to enable communications between a head and a base of a 2-in-1 computing device to enable the head to be positioned at different angles such that the transceivers in the head and base do not need to be in close proximity nor within a line of sight of each other.
In some embodiments, the waveguide may use a design that enables the head to be attached to the base in either a forward configuration or a reverse configuration. For example, the waveguide may include multiple prongs, where a first portion of the prongs are used for communications when the head is attached to the base in the forward configuration and a second portion of the prongs are used when the head is attached to the base in the reverse configuration.
FIG. 1 illustrates an example of a computing device that includes a head and a base according to some embodiments. FIG. 1 includes a computing device 102 that is comprised of a head 104 and a base 106.
The head 104 may include a display, one or more processors, and computer-readable storage media to store instructions. The one or more processors may access the computer-readable storage media to execute the instructions to perform various functions. For example, the head 104 may be detached from the base 106 for use as a tablet computing device. The head 104 may receive input via a touch screen display using a finger (or other appendage), a stylus, a keyboard superimposed on the touch screen display, another type of touch input mechanism, or any combination thereof.
The head 104 may receive input via buttons, a microphone (e.g., using voice recognition), another type of input mechanism, or any combination thereof.
The base 106 may include resources, such as one or more input devices (e.g., a keyboard, a touch pad, etc.), one or more storage devices (e.g., random access memory (RAM), disk drives, etc.), one or more input/output (I/O) ports (e.g., a universal serial bus (USB) port, a high definition multimedia interface (HDMI) port, a card reader (e.g., for reading a compact flash card, a secure digital (SD) card, etc.), another type of computing resource, or any combination thereof. When the head 104 is coupled to the base 106, the head 104 and the base 106 may be capable of contactless communication with each other. When coupled to the base 106, the head 104 may access one or more of the resources of the base 106. For example, the head 104 may receive input from the input devices of the base 106. The head 104 may display the input received from the base on the touchscreen display device of the head 104. The head 104 may store data on a storage device of the base 106. The head 104 may retrieve data stored on a storage device of the base 106 (or connected to the base 106 using an I/O port) and display at least part of the data on the touchscreen display device of the head 104. Of course, other examples of a head and a base may have other I/O devices and components.
The head 104 may be capable of being physically coupled to the base 106 and later de-coupled from the base 106. The base 104 includes a head transceiver 108 and a head waveguide 110. The base 106 includes a base waveguide 112 and a base transceiver 114. In some embodiments, the head waveguide 110 may be mounted off-center in such a way that the head waveguide 110 is in close proximity to a first portion of the base waveguide 112 in a forward orientation and, when the head 104 is reversed relative to the base 106, the head waveguide 110 is in close proximity to a second portion of the base waveguide 112 in a reverse orientation.
The transceivers 108, 114 and waveguides 110, 112 may operate at radio frequencies in the extremely high frequency (EHF) band, e.g., between 30 Gigahertz (GHz) and 300 GHz. For example, in a particular embodiment, the transceivers 108, 114 may communicate at approximately 60 GHz. In some embodiments, the transceivers 108, 114 may be implemented using a technology such as complementary metal oxide semiconductor (CMOS). The transceivers 108, 114 may be capable of transmitting and receiving signals with a bandwidth of 5 Gigabits per second (Gbps) or more. The transceivers 108, 114 and waveguides 110, 112 do not make contact each other. The transmitter component of the transceivers 108, 114 is used to transmit signals and the receiver component of the transceivers 108, 114 is used to receive signals.
When transmitting from the head 104 to the base 106, the head transceiver 108 may receive data from a component of the head 104, encode the data into a signal (e.g., carrier signal), and transmit the signal. The head waveguide 110 may conduct (e.g., guide) the signal to the base waveguide 112. The base waveguide 112 may conduct the signal to the base transceiver 114. The base transceiver 114 may receive the signal, decode the data from the signal, and send the data to one or more of the components (e.g., resources) of the base 106.
When transmitting from the base 106 to the head 104, the base transceiver 114 may receive data from a component of the base 106 and encode the data into the a signal. The base waveguide 112 may conduct (e.g., guide) the signal to the head waveguide 110. The head waveguide 110 may conduct the signal to the head transceiver 108. The head transceiver 108 may receive the signal, extract (e.g., decode) the data from the signal, and send the to one or more of the components of the head 104.
Thus, a computing device 102 may include a head 104 and a base 106 that uses contactless communication to communicate with each other when the head 104 is physically coupled to the base 106. The contactless communication may be achieved using a first transceiver that receives data and transmits the data using an EHF signal as the carrier. A first waveguide may transmit the EHF signal to a second waveguide. The second waveguide may receive the EHF signal and guide the signal to a second transceiver that extracts the data from the signal and sends the data to a destination. The waveguides 110, 112 and transceivers 108, 114 may be positioned to enable the head to rotate relative to the base. For example, a user may place the head 104 in different orientations (e.g., a forward orientation or a reverse orientation) and at different angles relative to the base 106 without affecting the ability of the head 104 and the base 106 to communicate with each other.
FIG. 2 illustrates an example of a head of a computing device coupling to a base according to some embodiments. FIG. 2 shows how the head 104 may physically couple to the base 106. For example, the head 104 may include a cylindrical protrusion that may be placed into a semi-circular groove in the base 106 to couple the head 104 to the base 106.
After the head 104 is coupled to the base 106, the head 104 may be placed at various angles relative to the base 106, while the distance between a tip 202 of the head waveguide 110 and the base waveguide 112 is relatively constant (e.g., does not change significantly), as shown in FIG. 2. The tip 202 of the head waveguide 110 is a portion of the head waveguide 110 that is located at an opposite end from the head transceiver 108. Thus, the distance between the tip 202 of the head waveguide 110 and the base waveguide 112 may remain relatively constant, thereby enabling contactless communication between the head 104 and the base 106 regardless of the angle between the head 104 and the base 106.
FIG. 3 illustrates an example of a head waveguide and a base waveguide according to some embodiments. FIG. 3 illustrates how the distance between the head waveguide 110 and the base waveguide 112 remains relatively constant regardless of the angle between the head 104 and the base 106, thereby enabling contactless communication between the head 104 and the base 106.
The head waveguide 110 includes at least one prong 302. Purely for illustration purposes, the head waveguide 110 is illustrated in FIG. 2 as including seven prongs. Of course, depending on the embodiment, the head waveguide 110 may have more than seven prongs or few than seven prongs. The base waveguide 112 includes at least one prong 304. For example, in embodiments where the head 104 may be coupled to the base 106 in both a forward orientation and a reverse orientation, the base waveguide 112 may include at least one prong in a center location.
As illustrated in FIG. 3, when transmitting from the head 104 to the base 106, the head transceiver 108 may receive data 306 from a component of the head 104 and encode the data 306 into a signal 308. The head waveguide 110 may conduct (e.g., guide) the signal 308 to the base waveguide 112. The base waveguide 112 may conduct the signal 308 to the base transceiver 114. The base transceiver 114 may receive the signal 308, extract the data 306 from the signal 308, and send the data 306 to one or more of the components (e.g., resources) of the base 106.
When transmitting from the base 106 to the head 104, the base transceiver 114 may receive data 306 from a component of the base 106 and encode the data 306 into a signal 308. The base waveguide 112 may conduct (e.g., guide) the signal 308 to the head waveguide 110. The head waveguide 110 may conduct the signal 308 to the head transceiver 108. The head transceiver 108 may receive the signal 308, extract the data 306 from the signal 308, and send the data 306 to one or more of the components (e.g., the touchscreen display) of the head 104.
Thus, the waveguides 110, 112 may include one or more prongs 302, 304 that are used to guide a signal from one waveguide to another waveguide. The transceivers 108, 114 may encode the data 302 into the signal 304 for transmission via the waveguides 110, 112 and decode the data 302 from the signal 304.
FIG. 4A illustrates an example of a forward orientation of a head and a base according to some embodiments. In the forward orientation 502, the head 104 may be attached to the base 106 in such a way that a touchscreen display of the head 104 may face forward, e.g., towards a user. In the forward orientation 502, the prongs of the head waveguide 110 may be positioned in close proximity to (e.g., over) a first portion of the prongs of the base waveguide 112. For example, the prongs of the head waveguide 110 may be positioned in close proximity to the middle prong and the prongs to the right of the middle prong of the base waveguide 112.
FIG. 4B illustrates an example of a reverse orientation of a head and a base according to some embodiments. In the reverse orientation 504, the head 104 may be attached to the base 106 in such a way that a touchscreen display of the head 104 may face back, e.g., away from a user. For example, a user may use the reverse orientation 504 to display something to another person or the user may position the head over the base to enable the computing device 102 to be used as a tablet computer. In the reverse orientation 504, the prongs of the head waveguide 110 may be positioned in close proximity to (e.g., over) a portion of the prongs of the base waveguide 112. For example, the prongs of the head waveguide 110 may be positioned in close proximity to the middle prong and the prongs to the left of the middle prong of the base waveguide 112.
While the base waveguide 112 is illustrated as including U-shaped prongs, in some embodiments, different shaped prongs may be used to enable multiple orientations. In embodiments that enable the head 104 to attach to the base 106 in more than one orientation, the prongs of the base waveguide 112 may be arranged symmetrically to enable the forward orientation 502 and the reverse orientation 504.
FIG. 5 illustrates examples of different placements of a head relative to a base according to some embodiments. The head 104 may be attached to the base 106 in a forward orientation 502 or in a reverse orientation 504. For example, the head 104 may be attached to the base 106 by placing a cylindrically shaped end 506 of the head 104 in a groove 508 (e.g., semi-circular shaped groove) of the base 106. In the forward orientation 502, the head 104 may be attached to the base 106 such that the touchscreen display is facing a user of the computing device 102. In the reverse orientation 504, the head 104 may be attached to the base 106 such that the touchscreen display is facing away from the user of the computing device 102.
As illustrated in FIG. 5, in both the forward orientation 502 and the reverse orientation 504, the head 104 may be placed at different angles relative to the base 106. The waveguides 110, 112 may provide a contactless connection between the head 104 and the base 106 to enable the head 104 to communicate with the base 106 regardless of the position of the head 104 relative to the base 106.
FIG. 7 illustrates examples of waveguide shapes according to some embodiments. For example, 702 illustrates an implementation of the base waveguide 112 that includes U-shaped prongs. 704 illustrates an implementation of the base waveguide 112 that includes rectangular-shaped prongs. 706 illustrates an implementation of the base waveguide 112 that includes prongs that incorporate a geometric shape (e.g., three sides of a square). Of course, in keeping with the techniques and systems described herein, any type of shape may be used for the base waveguide 112 such that the shape enables two or more components (e.g., the head 104 and base 106) of a computing device to be placed at different positions relative to each other while enabling near field communication between the two or more components. As illustrated in 702, 704, 706, some implementations of the base waveguide 112 may include a center prong, such that there are an odd number of prongs. However, other implementations of the base waveguide 112 may include an even number of prongs, e.g., by using two center prongs or by excluding the center prong.
