The present disclosure relates to portable electronic devices, and in particular to portable electronic devices having a slidable upper housing and lower housing movable between an open position and a closed position, and including a plurality of position sensors for detecting the position of the portable electronic device and whether the portable electronic device is in a holster.
Electronic devices, including portable electronic devices, have gained widespread use and may provide a variety of functions including, for example, telephonic, electronic text messaging and other personal information manager (PIM) application functions. Portable electronic devices can include several types of devices including mobile stations such as simple cellular phones, smart phones, Personal Digital Assistants (PDAs), tablets and laptop computers.
Devices such as PDAs or smart phones are generally intended for handheld use and ease of portability. Smaller devices are generally desirable for portability. In some cases, such devices may be touch sensitive devices. For example, touch-sensitive devices constructed of a display, such as a liquid crystal display (LCD), with a touch-sensitive overlay may be useful on some handheld devices as such handheld devices tend to be small and are therefore limited in space available for user input and output devices. Further, in some cases the screen content on the touch-sensitive devices can be modified depending on the functions and operations being performed. In other examples, some personal electronic devices may not have touch sensitive displays.
Embodiments of the present disclosure will now be described, by way of example only, with reference to the attached Figures, wherein:
In some embodiments, described herein is an electronic device that includes a housing, a touch-sensitive display exposed by a front of the housing, and functional components comprising a memory and a processor coupled to the memory and the touch-sensitive display.
It will be appreciated that for simplicity and clarity of illustration, where considered appropriate, reference numerals may be repeated among the figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein may be practiced without these specific details. In other instances, well-known methods, procedures and components have not been described in detail so as not to obscure the example embodiments described herein. The description is not to be considered as limited to the scope of the example embodiments described herein.
The portable electronic device 100 includes multiple components such as a processor 102 that controls the operations of the portable electronic device 100. Communication functions, including data communications, voice communications, or both, may be performed through a communication subsystem 104. Data received by the portable electronic device 100 may be decompressed and decrypted by a decoder 106. The communication subsystem 104 may receives messages from and send messages to a wireless network 150.
Generally, the wireless network 150 may be any type of wireless network, including, but not limited to, data-centric wireless networks, voice-centric wireless networks, and dual-mode networks that support both voice and data communications over the same physical base stations.
The portable electronic device 100 may be a battery-powered device and as shown may include a battery interface 142 for receiving one or more rechargeable batteries 144.
The processor 102 may also interact with additional subsystems such as a Random Access Memory (RAM) 108, a flash memory 110, a display 112 with a touch-sensitive overlay 114 connected to an electronic controller 116 that together may comprise a touch-sensitive display 118, an actuator assembly 120, one or more optional force sensors 122, an auxiliary input/output (I/O) subsystem 124, a data port 126, a speaker 128, a microphone 130, a short-range communications subsystem 132 and other device subsystems 134.
In some embodiments, user-interaction with the graphical user interface may be performed through the touch-sensitive overlay 114. The processor 102 may interact with the touch-sensitive overlay 114 via the electronic controller 116. Information, such as text, characters, symbols, images, icons, and other items that may be displayed or rendered on a portable electronic device, may be displayed on the touch-sensitive display 118 via the processor 102.
The processor 102 may also interact with an accelerometer 136 as shown in
To identify a subscriber for network access according to the present embodiment, the portable electronic device 100 may use a Subscriber Identity Module or a Removable User Identity Module (SIM/RUIM) card 138 inserted into a SIM/RUIM interface 140 for communication with a network (such as the wireless network 150). Alternatively, user identification information may be programmed into the flash memory 110.
The portable electronic device 100 may also include an operating system 146 and software components 148 that may be executed by the processor 102 and which may be stored in a persistent store such as the flash memory 110. Additional applications may be loaded onto the portable electronic device 100 through the wireless network 150, the auxiliary I/O subsystem 124, the data port 126, the short-range communications subsystem 132, or any other suitable device subsystem 134.
In use, a received signal such as a text message, an e-mail message, or web page download may be processed by the communication subsystem 104 and input to the processor 102. The processor 102 then processes the received signal for output to the display 112 or alternatively to the auxiliary I/O subsystem 124. A subscriber may also compose data items, such as e-mail messages, for example, which may be transmitted over the wireless network 150 through the communication subsystem 104.
For voice communications, the overall operation of the portable electronic device 100 may be similar. For example, the speaker 128 may output audible information converted from electrical signals, and the microphone 130 may convert audible information into electrical signals for processing.
Turning now to
As shown, one or both of the upper housing 202 and lower housing 204 may include one or more input apparatus, such as navigation keys or buttons, a physical or virtual keyboard, a trackpad, trackball, multimedia keys, etc. For example, the upper housing 202 as shown includes an auxiliary input device 212. The auxiliary input device may be an optical navigation module (e.g. a trackpad) that responds to user interaction, and which may be used for navigating around the display screen 206, to select objects on the display screen, or for other purposes. In some other embodiments, the auxiliary input device 212 may be a mechanical device that responds to user interaction (e.g. a trackball).
The display 206 and the auxiliary input device 212 may be generally disposed on a front of the upper housing 202 and exposed for user accessibility when the portable electronic device 200 is in either of the open or closed positions.
The upper housing 202 may also include other input devices, such as a dedicated phone application button, a dedicated “disconnect call” button, a home screen button, etc. In various embodiments, one or more of these input devices may include optical sensors, mechanical buttons, or both.
Turning now to the lower housing 204, the lower housing 204 may include various buttons and other controls, such as buttons 208 and 210, and which could be used for navigation, to control volume or for other purposes.
The lower housing 204 could also include one or more application buttons 211 that can be used to automatically launch a particular application on the portable electronic device (e.g. a camera application, a phone application, etc.). In some embodiments, the button 211 may be configurable by a user (e.g. the user may be able to select the particular application or function that is launched by the button 211).
As shown in
As shown, the lower housing 204 may also include a battery cover 216 for covering the battery. In some embodiments, the battery cover 216 may be removable. In other embodiments, the battery cover 216 may be permanently fixed to the device.
In some embodiments, the lower housing 204 may also include an audio jack 217. The audio jack 217 may be used to couple the portable electronic device 200 to an accessory such as a speaker, a microphone, or both, for example for use in voice communication.
Turning now to
As shown in
Alternatively, when the portable electronic device 200 is in the open position (as shown in
In some embodiments, the display 206 may be a touch-sensitive display. The touch-sensitive display may be a capacitive touch-sensitive display, for example, and a user's touch on the touch-sensitive display may be determined by determining an X and Y location of the touch, with the X location determined by a signal generated as a result of capacitive coupling with a touch sensor layer and the Y location determined by the signal generated as a result of capacitive coupling with another touch sensor layer. Each of the touch-sensor layers may provide a signal to a controller that represents the respective X and Y touch location values. Thus a feature such as a virtual button or other feature displayed on the touch-sensitive display may be selected by a mapping of the touch location to a feature on the touch-sensitive display.
In some embodiments, the portable electronic device 200 is generally taller than it is wide. In such embodiments, as the portable electronic device 200 moves between the open position and the closed position, the upper housing 202 and lower housing 204 move along a longitudinal axis of the portable electronic device 200.
In some embodiments, the portable electronic device 200 is provided with a holster 234 (see
Portable electronic devices that are movable between multiple positions (i.e. an open position and a closed position, such as portable electronic device 200) typically include at least one sensor to detect the position of the portable electronic device. This tends to allow for enabling or disabling of certain features based on the position of the portable electronic device 200. For example, power may be supplied to some or all the input devices (i.e. display screen 206, auxiliary input device 212, buttons 208 and 210, application button 211 and the keypad 220) when the portable electronic device 200 is in the open position, and power may be cut-off to some or all of the input devices (i.e. keypad 220) when the portable electronic device 200 is in the closed position.
It is also typically beneficial to know when the portable electronic device 200 is in the holster 234. In some embodiments, for example, this may allow for configurable notification settings. For example, in one configuration the portable electronic device 200 may use a vibration alert for an incoming call when the portable electronic device 200 is in the holster 234, and a ring alert for an incoming call when the portable electronic device 200 is out of the holster 234. Other notification settings may also be selected and be dependent on whether the portable electronic device 200 is in the holster 234 or out of the holster 234.
Furthermore, in some embodiments various features may be disabled when the portable electronic device 200 is in the holster 234. This may be beneficial as it may aid in reducing power consumption.
In some embodiments, the portable electronic device 200 includes two position sensors for detecting when the portable electronic device 200 is in one of three positions: (1) open position (i.e. the keypad 220 is exposed); (2) closed position (i.e. the keypad 220 is covered); and (3) holster position (i.e. when the portable electronic device 200 is in the holster 234).
Reference is now made to
The two position sensors 230 and 232 are typically situated on opposite housing modules (e.g. one position sensor is situated on the upper housing 202, and one position sensor is situated on the lower housing 204). For example, in the embodiment shown in
The first position sensor 230 and the second position sensor 232 cooperate together to detect whether the portable electronic device 200 is in the open position, the closed position or the holster position (i.e. the portable electronic device 200 is in the holster 234). Specifically, in some embodiments each position sensor 230 and 232 may be operable detect the presence of one or more corresponding objects or fields (i.e. magnetic field) and output a sensor output signal indicating the presence or absence of the corresponding objects or fields.
The position sensors 230 and 232 are positioned sufficiently far apart on the upper and lower housings 202 and 204 respectively so that regardless of the position (open/closed/holster) of the portable electronic device 200 both sensors 230 and 232 normally cannot be triggered by the same object or field simultaneously. Specifically, the position sensors 230 and 232 may be positioned sufficiently far apart so that the objects or fields used to trigger the first position sensor 230 will not simultaneously trigger the second position sensor 232, and the objects or fields used to trigger the second position sensor 232 will not simultaneously trigger the first position sensor 230.
In some embodiments, the sensor output signal produced by the position sensors 230 and 232 is a binary signal (i.e. High/Low, On/Off, 1/0, etc.) that indicates either (i) the presence of a corresponding object or field; or (ii) the absence of a corresponding object or field. In these embodiments, the positions sensors 230 and 232 can be thought of as either “ON” (presence of a corresponding object or field), or “OFF” (absence of a corresponding object or field).
In some embodiments the position sensors 230 and 232 are magnetic sensors, such as Hall Effect Sensors, that detect the presence of a magnetic field. As is known to those of skill in the art, a Hall Effect Sensor is a transducer that varies its output voltage in response to changes in magnetic field. In the embodiment shown in
The first magnet 236 may be positioned in an upper portion 242 of the lower housing 204 so that when the portable electronic device 200 is in the open position the first magnet 236 aligns with the first position sensor 230 (see
In one embodiment, the first magnet 236 is the magnet inherent in the speaker of the portable electronic device 200 (i.e. speaker 128). Accordingly, in this embodiment, a separate magnet is not required to detect whether the portable electronic device 200 is in the open position. This may reduce the cost of the portable electronic device 200. This may also reduce the size of the portable electronic device 200.
In some embodiments, the third magnet 240 is positioned in a lower portion 244 of the upper housing 202 so that when the portable electronic device 200 is in the closed position the third magnet 240 aligns with the second position sensor 232 (see
The first magnet 236 may be positioned on the upper portion 242 of the lower housing 204 so that when the portable electronic device 200 is in the closed position there is sufficient distance between the first magnet 236 and the first position sensor 230 so that the first position sensor 230 will not detect the magnetic field produced by the first magnet 236. Accordingly, when the portable electronic device 200 is in the closed position, the first position sensor 230 will be “OFF” and the second position sensor 232 will be “ON”.
As shown in
In some embodiments, since generally the portable electronic device 200 can typically only be put in the holster 234 when in the closed position, when the portable electronic device 200 is in the holster position, typically both the first position sensor 230 and the second position sensor 232 will be “ON”.
In some embodiments, the first position sensor 230 produces a single sensor output signal that indicates the presence or absence of a magnetic field irrespective of which magnet (i.e. the first magnet 236 or the second magnet 238) produced the magnetic field. In other embodiments, the first position sensor 230 may produce multiple sensor output signals, each signal indicating the presence or absence of a specific magnetic field. For example, the first position sensor 230 may produce a first sensor output signal that indicates the presence or absence of the magnetic field produced by the first magnet 236, and a second sensor output signal that indicates the presence or absence of the magnetic field produced by the second magnet 238.
In one embodiment, the first position sensor 230 is a polarity-dependent magnetic sensor that produces two sensor output signals. The first sensor output signal indicates the presence or absence of an N-pole magnetic field, and the second sensor output signal indicates the presence or absence of an S-pole magnetic field. In this embodiment, the first position sensor 230 is capable of distinguishing an N-pole magnetic field produced by one magnet (i.e. the first magnet 236) from an S-pole magnetic field produced by another magnet (i.e. the second magnet 238). Accordingly, if one of the first and second magnets 236 and 238 produces an N-pole magnetic field and the other produces an S-pole magnetic field, the first position sensor 230 can distinguish between the magnetic field produced by the first magnet 236 and the magnetic field produced by the second magnet 238.
In another embodiment, the first position sensor 230 may include a plurality of dies with different magnetic field strength triggering points in a single package. For example, if the first magnet 236 produces a magnetic field of strength A, and the second magnet 238 produces a magnetic field of strength B, the first position sensor 230 may be provided with two dies. The first die may trigger above magnetic field strength A, and the second die may trigger above magnetic field strength B. It may then be possible to determine which of the two magnets (the first magnet 236 or the second magnet 238) triggered the first position sensor 230 based on which of the two dies was triggered.
Although the position sensors 230 and 232 have been described above as being magnetic sensors, it will be evident to a person of skill in the art that other types of sensors may be used. For example, in other embodiments, the positions sensors 230 and 232 may be proximity sensors. However, if proximity sensors are used, objects, such as a user's hand, may interfere with the proximity sensor's ability to accurately detect the position of the portable electronic device.
In other embodiments the position sensors 230 and 232 may be mechanical sensors, such as a mechanical switch.
In some embodiments, the portable electronic device 200 may also include a state determiner (not shown) that receives the sensor output signals from the position sensors 230 and 232 and determines the position of the portable electronic device 200 based on the sensor outputs signals. For example, in the embodiment shown in
The state determiner may be implemented in software, hardware, firmware or any appropriate combination thereof. In one embodiment, the state determiner is implemented in software that is executed on the processor (i.e. processor 102) of the portable electronic device 200. In other embodiments, the state determiner is separate and distinct from the processor (i.e. processor 102).
In some embodiments, the processor (i.e. processor 102) may execute one or more actions based on the position of the portable electronic device 200. For example, the processor (i.e. processor 102) may provide power to one or more input devices (i.e. display screen 206, auxiliary input device 212, buttons 208 and 210, application button 211 and the keypad 220) when the portable electronic device 200 is in the open position, and disable or turn off power to at least one of the input devices (i.e. keypad 220) when the portable electronic device 200 is in the closed position. In some embodiments, all input devices (i.e. display screen 206, auxiliary input device 212, buttons 208 and 210, application button 211 and the keypad 220) may be disabled when the portable electronic device 200 is in the holster position.
In a further example, the processor (i.e. processor 102) may provide visual notification of an incoming call using the display screen 206 when the portable electronic device 200 is in the open position or the closed position, and an audio notification of an incoming call when the portable electronic device 200 is in the holster position. It will be evident to a person of skill in the art that these are exemplary actions only and the processor (i.e. processor 102) may be configured to execute other actions based on the position of the portable electronic device 200.
While the above description provides examples of one or more processes or apparatuses, it will be appreciated that other processes or apparatuses may be within the scope of the accompanying claims.
