20120176249
The use of docking stations and other accessory devices in connection with mobile computing devices (e.g. smart phones, media players etc.) is well known. Traditionally, docking stations are used to (i) recharge or supply power to the mobile computing device, (ii) enable the computing device to communicate with other devices connected to the docking station (e.g. synchronization with a personal computer), or (iii) use additional resources provided with the docking station (e.g. speakers for audio output).
In a traditional scheme, docking stations and mobile computing devices connect using insertive male/female connectors. Numerous factors come into consideration when mobile devices are designed with connectors for use with docking stations. For example, such connectors typically take into account the ease by which users may establish the connection (e.g. can the user simply drop the device into the cradle), as well as the mechanical reliability of the connectors. When users repeatedly mate devices with docking stations, both the mating action and the removal of the device from the docking station can strain the connector structure and its elements.
Some embodiments of the invention are described, by way of example, with respect to the following figures:
Figure (FIG.) 1a illustrates one example embodiment of a mobile computing device that is placed proximate to a docking station.
b illustrates one example embodiment of a mobile computing device that is placed proximate to a docking station.
a is a diagram of a system, according to an example embodiment, illustrating the placement of the mobile computing device 110 to be proximate to a docketing station 201.
b is a diagram of a system, according to an example embodiment, illustrating the example placement of the mobile computing device proximate to the docketing station.
c is a diagram of the system, according to an example embodiment, illustrating an case where the mobile computing device is no longer proximate to the docketing station resulting in the activation of the alarm.
Illustrated is a system and method to activate an alarm where a mobile computing device is no longer proximate to a docking station that provides inductive charging and data transfer capabilities for the mobile computing device. An alarm, as used herein, is visual and/or audible indicia of an event. Example visual indicia are an illuminated Light Emitting Diode (LED). An example of audible indicia is a human detectable sound (e.g., a sound between 20 Hz and 20,000 Hz). This human detectable sound may be constant, intermittent, and may vary in terms of pitch and tone. An example of an event is the removal of a mobile computing device from a docking station that provides inductive charging and/or data transfer capabilities. An example of a docking station that provides inductive charging and data transfer capabilities (referenced herein as a “docking station”) for the mobile computing device is provide in U.S. patent application Ser. No. 12/239,656 titled “Orientation and Presence Detection For Use in Configuring Operations of Computing Devices In Docked Environments.”
In one example embodiment, a mobile computing device is determined to be no longer proximate to a docking station such that an alarm is activated. Specifically, in cases where a mobile computing device is determined to be no longer proximate to a docking station, the alarm logic is executed to activate an alarm. In some example embodiments, the alarm is activated where the mobile computing device is no longer proximate to another computer system, smart phone, slate computer, printer, display or other suitable device. The proximity sensor determines that the mobile computing device is proximate to the docketing station, and where such a determination is made the alarm is set. The proximity sensor may use one or more of the following method to set the alarm: a magnetically based proximity switch, a mechanical switch, an acoustic sensor, a Hall-Effect Sensor, an IR Sensor, or some other suitable sensor. To set, as used herein, may include closing or opening an electrical circuit, initializing a numeric or Boolean value in a memory, or some other suitable process. When the mobile computing device is removed from the docking station (i.e., the mobile computing device is no longer proximate to the docking station), the proximity sensor is de-activated and the alarm is activated. The alarm may be activated by the closing or opening of an electrical circuit, initializing a numeric or Boolean value in a memory, or some other suitable process. The aforementioned visual or audible indicia may emanate from the docketing station, the mobile computing device or both the docketing station and mobile computing device. In some example embodiments, the determination of mobile computing device proximity is carried out by a docking station processor executing logic stored in memory on the docking station.
a and 1b illustrate one embodiment of a mobile computing device 110 that is placed proximate to a docking station.
It is noted that for ease of understanding the principles disclosed herein are in an example context of a mobile computing device 110 with telephonic functionality operating in a mobile telecommunications network. However, the principles disclosed herein may be applied in other duplex (or multiplex) telephonic contexts such as devices with telephonic functionality configured to directly interface with Public Switched Telephone Networks (PSTN) and/or data networks having Voice over Internet Protocol (VoIP) functionality. Likewise, the mobile computing device 110 is only by way of example, and the principles of its functionality apply to other computing devices, e.g., desktop computers, slate devices, server computers and the like.
The mobile computing device 110 includes a first portion 110a and a second portion 110b. The first portion 110a comprises a screen for display of information (or data) and may include navigational mechanisms. These aspects of the first portion 110a are further described below. The second portion 110b comprises a keyboard and also is further described below. The first positional state of the mobile computing device 110 may be referred to as an “open” position, in which the first portion 110a of the mobile computing device slides in a first direction exposing the second portion 110b of the mobile computing device 110 (or vice versa in terms of movement). The mobile computing device 110 remains operational in either the first positional state or the second positional state.
The mobile computing device 110 is configured to be of a form factor that is convenient to hold in a user's hand, for example, a Personal Digital Assistant (PDA) or a smart phone form factor. For example, the mobile computing device 110 can have dimensions ranging from 7.5 to 15.5 centimeters in length, 5 to 15 centimeters in width, 0.5 to 2.5 centimeters in thickness and weigh between 50 and 250 grams.
The mobile computing device 110 includes a speaker 120, a screen 130, and an optional navigation area 140 as shown in the first positional state. The mobile computing device 110 also includes a keypad 150, which is exposed in the second positional state. The mobile computing device also includes a microphone (not shown). The mobile computing device 110 also may include one or more switches (not shown). The one or more switches may be buttons, sliders, or rocker switches and can be mechanical or solid state (e.g., touch sensitive solid state switch). The aforementioned alarm may emanate from the speaker 120.
The screen 130 of the mobile computing device 110 is, for example, a 240×240, a 320×320, a 320×480, or a 640×480 touch sensitive (including gestures) display screen. The screen 130 can be structured from, for example, such as glass, plastic, thin-film or composite material. In one embodiment the screen may be 1.5 inches to 5.5 inches (or 4 centimeters to 14 centimeters) diagonally. The touch sensitive screen may be a transflective liquid crystal display (LCD) screen. In alternative embodiments, the aspect ratios and resolution may be different without departing from the principles of the inventive features disclosed within the description. By way of example, embodiments of the screen 130 comprises an active matrix liquid crystal display (AMLCD), a thin-film transistor liquid crystal display (TFT-LCD), an organic light emitting diode (OLED), an Active-matrix OLED (AMOLED), an interferometric modulator display (IMOD), a liquid crystal display (LCD), or other suitable display device. In an embodiment, the display displays color images. In another embodiment, the screen 130 further comprises a touch-sensitive display (e.g., pressure-sensitive (resistive), electrically sensitive (capacitive), acoustically sensitive (SAW or surface acoustic wave), photo-sensitive (infra-red)) including a digitizer for receiving input data, commands or information from a user. The user may use a stylus, a finger or another suitable input device for data entry, such as selecting from a menu or entering text data.
The optional navigation area 140 is configured to control functions of an application executing in the mobile computing device 110 and visible through the screen 130. For example, the navigation area includes an x-way (x is a numerical integer, e.g., 5) navigation ring that provides cursor control, selection, and similar functionality. In addition, the navigation area may include selection buttons to select functions displayed through a user interface on the screen 130. In addition, the navigation area also may include dedicated function buttons for functions such as, for example, a calendar, a web browser, an e-mail client or a home screen. In this example, the navigation ring may be implemented through mechanical, solid state switches, dials, or a combination thereof. In an alternate embodiment, the navigation area 140 may be configured as a dedicated gesture area, which allows for gesture interaction and control of functions and operations shown through a user interface displayed on the screen 130.
The keypad area 150 may be a numeric keypad (e.g., a dialpad) or a numeric keypad integrated with an alpha or alphanumeric keypad or character keypad 150 (e.g., a keyboard with consecutive keys of Q-W-E-R-T-Y, A-Z-E-R-T-Y, or other equivalent set of keys on a keyboard such as a DVORAK keyboard or a double-byte character keyboard).
Although not illustrated, it is noted that the mobile computing device 110 also may include an expansion slot. The expansion slot is configured to receive and support expansion cards (or media cards). Examples of memory or media card form factors include COMPACT FLASH, SD CARD, XD CARD, MEMORY STICK, MULTIMEDIA CARD, SDIO, and the like.
a is a diagram of a system 200 illustrating the example placement of the mobile computing device 110 to be proximate to a docketing station 201. Shown is the mobile computing device 110 that is placed to reside on the docketing station 201. This placement is illustrated at 208. The docking station 201 includes a number of components including a plurality of proximity sensors 202. While a plurality of sensors is illustrated, one sensor may be used in lieu of a plurality of proximity sensors 202. The proximity sensors 202 are operatively connected to a processor 206. Operatively connected, as used herein, includes a logical or physical connected. The processor 206 is operatively connected to a speaker 205 and an alarm logic module 207. The speaker 205 is used to generate an audible indicia of an event such as the removal of the mobile computing device 110 from the docking station 201. The alarm logic module may be memory upon which logic or instructions executable by the processor 206 reside.
b is a diagram of the system 200 illustrating the example placement of the mobile computing device 110 proximate to the docketing station 201. In cases where the mobile computing device 110 is proximate to the docking station 201, an alarm may be set. To set, as used herein, may include closing or opening an electrical circuit, initializing a numeric or Boolean value in a memory, or some other suitable process. The proximate nature of the mobile computing device 110 and the docking station 201 is reflected at 209. An example of proximate is between 0-2 mm distance between the mobile computing device 110 and the docking station 201.
c is a diagram of the system 200 illustrating an example case where the mobile computing device 110 is no longer proximate to the docketing station 201 resulting in the activation of the alarm. Illustrated at 210 is the removal of the mobile computing device 110 from the docking station 201. This removal results in the mobile computing device 110 no longer being proximate to the docketing station 201. As will be discussed in more detail below, one or more of the sensors 202 detect that the mobile computing device 110 is no longer proximate to the docking station 201. The event of the removal of the mobile computing device, triggers an audible or visual indicia in the form of an alarm. The alarm itself may be activated by the closing or opening of an electrical circuit, initializing a numeric or Boolean value in a memory, or some other suitable process. An audible indicia in the form of a sound generated by the speaker 205 is shown at 211. An additional audible indicia in the form of sound generated by the mobile computing device 110, and a speaker 120 associated therewith, is shown at 212. The audible indicia illustrated at 211 and 212 may be generated separately or in combination.

The central processor 820 is configured for operation with a computer operating system 820a. The operating system 820a is an interface between hardware and an application, with which a user typically interfaces. The operating system 820a is responsible for the management and coordination of activities and the sharing of resources of the mobile computing device 110. The operating system 820a provides a host environment for applications that are run on the mobile computing device 110. As a host, one of the purposes of an operating system is to handle the details of the operation of the mobile computing device 110. Examples of an operating system include PALM OS and WEBOS, MICROSOFT WINDOWS (including WINDOWS 7, WINDOWS CE, and WINDOWS MOBILE), SYMBIAN OS, RIM BLACKBERRY OS, APPLE OS (including MAC OS and IPHONE OS), GOOGLE ANDROID, and LINUX.
The central processor 820 communicates with an audio system 810, an image capture subsystem (e.g., camera, video or scanner) 812, flash memory 814, RAM memory 816, and a short range radio module 818 (e.g., Bluetooth, Wireless Fidelity (WiFi) component (e.g., IEEE 802.11, 802.20, 802.15, 802.16)). The central processor 820 communicatively couples these various components or modules through a data line (or bus) 878. The power supply 840 powers the central processor 820, the radio subsystem 850 and a display driver 830 (which may be contact- or inductive-sensitive). The power supply 840 may correspond to a direct current source (e.g., a battery pack, including rechargeable) or an alternating current (AC) source. The power supply 840 powers the various components through a power line (or bus) 879.
The central processor communicates with applications executing within the mobile computing device 110 through the operating system 820a. In addition, intermediary components, for example, a charging detection logic 822 and data detection logic 826, provide additional communication channels between the central processor 820 and operating system 820 and system components, for example, the display driver 830.
It is noted that in one embodiment, central processor 820 executes logic (e.g., by way of programming, code, or instructions) corresponding to executing applications interfaced through, for example, the navigation area 140 or switches. It is noted that numerous other components and variations are possible to the hardware architecture of the computing device 800, thus an embodiment such as shown by
In one example embodiment, the charging detection logic 822 and data detection logic 826 is used to determine whether the mobile computing device 110 is being charged and/or is receiving or transmitting data. In cases where the mobile computing device 110 is no longer being charged or is no longer receiving or transmitting data the alarm logic 828 is executed and a visual or audible indicia is executed. As discussed above, the audible indicia may be generated using the speaker 120 that is operatively connected to the audio system 810 and alarm logic 828. Further, the visual indicia may be generated using an LED 880 that is operatively connected to the display driver 830 and alarm logic 828. The charging detection logic 822, data detection logic 826, and alarm logic 828 may reside as part of a module 899.
The radio subsystem 850 includes a radio processor 860, a radio memory 862, and a transceiver 864. The transceiver 864 may be two separate components for transmitting and receiving signals or a single component for both transmitting and receiving signals. In either instance, it is referenced as a transceiver 864. The receiver portion of the transceiver 864 communicatively couples with a radio signal input of the device 110, e.g., an antenna, where communication signals are received from an established call (e.g., a connected or on-going call). The received communication signals include voice (or other sound signals) received from the call and processed by the radio processor 860 for output through the speaker 120. The transmitter portion of the transceiver 864 communicatively couples a radio signal output of the device 110, e.g., the antenna, where communication signals are transmitted to an established (e.g., a connected (or coupled) or active) call. The communication signals for transmission include voice, e.g., received through the microphone of the device 110, (or other sound signals) that is processed by the radio processor 860 for transmission through the transmitter of the transceiver 864 to the established call.
In one embodiment, communications using the described radio communications may be over a voice or data network. Examples of voice networks include Global System of Mobile (GSM) communication system, a Code Division, Multiple Access (CDMA system), and a Universal Mobile Telecommunications System (UMTS). Examples of data networks include General Packet Radio Service (GPRS), third-generation (3G) mobile (or greater), High Speed Download Packet Access (HSDPA), High Speed Uplink Packet Access (HSUPA), and Worldwide Interoperability for Microwave Access (WiMAX).
While other components may be provided with the radio subsystem 850, the basic components shown provide the ability for the mobile computing device to perform radio-frequency communications, including telephonic communications. In an embodiment, many, if not all, of the components under the control of the central processor 820 are not required by the radio subsystem 850 when a telephone call is established, e.g., connected or ongoing. The radio processor 860 may communicate with central processor 820 using the data line (or bus) 878.
The card interface 824 is adapted to communicate, wirelessly or wired, with external accessories (or peripherals), for example, media cards inserted into the expansion slot (not shown). The card interface 824 transmits data and/or instructions between the central processor and an accessory, e.g., an expansion card or media card, coupled within the expansion slot. The card interface 824 also transmits control signals from the central processor 820 to the expansion slot to configure the accessory. It is noted that the card interface 824 is described with respect to an expansion card or media card; it also may be structurally configured to couple with other types of external devices for the device 110, for example, an inductive charging station (i.e., a docking station 201) for the power supply 840 or a printing device.
In the foregoing description, numerous details are set forth to provide an understanding of the present invention. However, it will be understood by those skilled in the art that the present invention may be practiced without these details. While the invention has been disclosed with respect to a limited number of embodiments, those skilled in the art will appreciate numerous modifications and variations therefrom. It is intended that the appended claims cover such modifications and variations as fall within the “true” spirit and scope of the invention.
