DETAILED DESCRIPTION
Some aspects of some embodiments according to the present disclosure may relate, for example, to systems and methods that provide an active cover for an electronic device or equipment.
Some embodiments according to the present disclosure provide that the active cover can sense when the electronic device is generating an alert or an indicator and can provide an enhanced alert or indicator instead of or in addition to the generated alert or indicator of the electronic device.
Some embodiments according to the present disclosure contemplate that the active cover includes a mobile phone cover for use with a mobile phone (e.g., a cellular handset, a cellular device, a wireless phone, a wireless handset, a multimode phone, a mobile phone compliant with multiple wireless communication standards, a mobile phone equipped with global positioning, a multiple-input-multiple-output phone, a wireless communication device, a two-way radio, communication devices with one or more antennas, etc.) The device and methods disclosed can also be used with tablets, tablet computers, and other devices as well.
Some embodiments according to the present disclosure contemplate that, during a mobile phone alert or event, an active mobile phone cover according to the sound or alert data generated by the mobile phone. The device may also illuminate in a distinct or random pattern, for example, according to the sound or alert data generated by the mobile phone. A distinct pattern can be assigned to associated sounds or alerts. For example, a distinct pattern can be assigned to a particular ring tone of the mobile phone. The active mobile phone can enhance the look and feel of the outside of the mobile phone cover, provide the user with superior sensory input over the mobile phone alone, and/or protect the mobile phone from drops, scratches, etc.
Some embodiments according to the present disclosure provide a mobile phone cover with light emitting diodes (LEDs) that are positioned at and/or near the edges and/or sides of a mobile phone. The mobile phone cover can use waveguides, for example, to bring light from the LEDs to illuminate a distinct pattern. The distinct pattern can be facilitated by, for example, diffusers and/or prisms (e.g., microprisms) that are optically coupled to the LEDs, for example, via the waveguides. The diffusers and/or prisms can enhance and/or influence the light generated by the LEDs.
Some embodiments according to the present disclosure provide a mobile phone cover with LEDs that are disposed in one or more bumper bands (e.g., a series of bumper bands) that are disposed, for example, around the mobile phone. The LEDs can facilitate, for example, edge lighting around one or more of the edges of a mobile phone.
Some embodiments according to the present disclosure provide, for example, suitable logic, circuitry, code or combinations thereof that may be adapted to perform the functions or acts described herein.
FIG. 1 illustrates an embodiment of a mobile phone cover according to some aspects of the present disclosure. A mobile phone cover 100 (e.g., a cover, a case, a shell, a protector, etc.) surrounds a mobile phone 110. In some embodiments according to the present disclosure, the mobile phone 110 may be slipped inside the mobile phone cover 100 and/or the mobile phone cover 100 can be snapped on or stretched around the mobile phone 110. The mobile phone cover 100 can be, for example, an accessory to and/or separate from the mobile phone 110. The mobile phone cover 100 can be adapted, for example, to provide physical vias (e.g., access openings and/or windows) through which various input interfaces and/or output interfaces can be accessed without removing the mobile phone cover 100 from the mobile phone 110. In some embodiments according to the present disclosure, the mobile phone cover 100 may provide a physical opening to access a display, a camera, a button, a control, other output interfaces, and/or other input interfaces of the mobile phone 110. In other embodiments, the mobile phone cover 100 may provide a transparent cover portion, for example, over a display or other portions of the mobile phone 110. The transparent cover portion can be made of materials that, for example, do not interfere with the operation of any of the touch screens of the mobile phone 110. The transparent cover portion may also protect areas of the mobile phone 110 such as touch screens from scratching or other damage.
Some embodiments according to the present disclosure may provide that the mobile phone cover 100 is made of one or more of the following: silicone, rubber, metal, plastic, polymers, composites, cloth, and/or other materials. The cover material may be, at least in part, opaque or transparent. The cover material may assist a user in gripping the mobile phone 110 and/or may protect the mobile phone 110, for example. The cover material may be, for example, shock resistant and/or shatter proof.
Some embodiments according to the present disclosure may provide that the mobile phone 110 include, for example, an audio port 120 (e.g., an audio and/or visual port, an earphone port, a headphone port, etc.), a speaker 130 and a docking port 140 (e.g., a data port, a recharging port, etc.) as illustrated in FIG. 1. Other components and ports of the mobile phone 110 might be not illustrated in the present application, but one of ordinary skill in the art would appreciate the various components and ports that are or can be part of a conventional mobile phone.
The mobile phone cover 100 is illustrated in FIG. 1 to include, for example, circuitry 150 and light emitting diodes (LEDs) 160. The circuitry 150 can be connected, for example, to the LEDs 150.
The mobile phone cover 100 can also include, for example, a battery 170 (e.g., a rechargeable battery, a watch battery, etc.) that can be used to power, for example, the circuitry 150 and/or the LEDs 160. Some embodiments according to the present disclosure provide that the battery 170 can be rechargeable or not rechargeable. If not rechargeable, the battery 170 can be replaced. Some embodiments of the battery 170 include, for example, a lithium battery, an alkaline battery, a silver-oxide battery, etc. If rechargeable, then the battery 170 can be recharged, for example, by drawing energy from the mobile phone 110 through the audio port 120, the docking port 140 and/or some other connection to the mobile phone 110. The battery 170 of the mobile phone cover 100 can be charged by a piezoelectric battery charger, for example. In some embodiments, the piezoelectric battery charger can convert force (e.g., caused by pressure, movements, mechanical forces, etc.) into electrical energy for use by the battery 170. Some embodiments contemplate converting other types of energy (e.g., sound, light, electromagnetic, magnetic, thermal, moving air, etc.) into electrical energy to charge the battery 170. The battery 170 of the mobile phone cover 100 can also be recharged when the mobile phone 110 is connected to a wall outlet, for example, such as when the docking port 140 is connected to a wall outlet. The battery 170 may receive energy directly from the wall outlet (e.g., via connecting the mobile phone cover 100 directly to the wall outlet) or through the mobile phone 110. In addition, the battery 170 may receive energy when the docking port 140 is connected to a computer, for example, and/or when the mobile phone 110 or mobile phone cover 110 is being synchronized. Some embodiments according to the present disclosure contemplate that the circuitry 150 receives power from the mobile phone 110 without using the battery 170. Thus, some embodiments according to the present disclosure might not have a dedicated battery as part of the mobile phone cover 100, or might use the battery 170 as a back-up power source.
The circuitry 150 may be, for example, embedded in the mobile phone cover 100. The circuitry 150 may include, for example, one or more circuit boards 150a including, for example, an integrated circuit. The circuitry 150 may also include, for example, one or more sensors 150b (e.g., an audio sensor, a signal sensor, an optical sensor, a wireless signal sensor, etc.) Components 150a and 150b can be part of the same circuit board or can be part of separate circuit boards, for example. A sensor can be part of components 150a and/or 150b. 
Some embodiments according to the present disclosure provide that at least some of the LEDs 160 are covered by at least partially transparent beads 180 (e.g., LED covers). Some embodiments according to the present disclosure provide that the beads 180 extend outwardly and/or inwardly from a surface of the mobile phone cover 100 to provide texture (e.g., a three dimensional texture) and design to the mobile phone cover 100. The beads 180 can be adapted to be or look like, for example, one or more of the following: jewels, crystals, rhinestones, glass, plastic, diamonds, bling, stones, pearls, logos (e.g., school logos, business logos, sports logos, etc.), mascots, artistic shapes, and whimsical shapes. FIG. 1A illustrates an embodiment of the mobile phone cover 100 with different types of beads and/or shapes. The mobile phone cover 100 can include, for example, other beads 190 that may or may not be similar to the beads 180, and that do not cover LEDs 160. The beads 180 and/or the beads 190 may be disposed on the front side, the back side, the inside, the outside, or any side of the mobile phone cover 100 and/or may receive illumination (e.g., scatter illumination) from other beads (e.g., adjacent beads 180 and 190). Adjacent bead lighting may be enhanced by, for example, maintaining a space from the back of the mobile phone 110 to the interior side of the mobile phone cover 100. This may allow stray light, for example, to shine from one bead to another.
Some embodiments according to the present disclosure may provide that the beads 180 and 190 may be made of or made to resemble, for example, one or more of the following: glass, rhinestones, stones, mineral, crystals, diamonds, logos (e.g., school logos, business logos, sports logos, etc.), mascots, artistic shapes, whimsical shapes, silicone, rubber, metals, plastic, polymers, composites, cloth, and/or other materials. The beads 180 and 190 may assist a user in gripping the mobile phone 110 and/or may protect the mobile phone 110, for example. The beads 180 and 190 may be of one or more materials that provide, for example, shock resistance and/or shatter protection. In addition, the beads 180 and 190 may be adapted to enhance the look or design of the mobile phone cover 100.
Some embodiments according to the present disclosure provide that the beads 180 and 190 can be colored or uncolored. Some embodiments according to the present disclosure provide that the LEDs 160 provide one or more colors. For example, FIG. 2 illustrates a colored or uncolored bead 180 covering a red LED 160a, a green LED 160b, and a blue LED 160c. Circuitry 150 or other circuitry may be used to drive the red LED 160a, the green LED 160b, and the blue LED 160c to generate any color with any intensity. Some embodiments provide that the beads 180 provide one or more colors when light from one or more LEDs are shown through the one or more colored beads 180, or the one or more colored beads 190 receives light scattered by beads 180 (e.g., adjacent beads).
In operation, some embodiments according to the present disclosure provide that the circuitry 150 enhances indications of a mobile phone alert or event such as, for example, a low battery indication, a roaming indication, an incoming call, a calendar alert, a caller identification, or an incoming/pending message (e.g., text message, video message, voicemail message, missed call message, etc.) by driving the LEDs 150 to light up in a particular manner. For example, when the battery in the mobile phone 110 is getting low, a red bead 180 may become illuminated or may flash on and off at intervals.
Some embodiments according to the present disclosure provide that, when the mobile phone 110 receives an incoming call or message, the mobile phone 110 may generate a particular indicator (e.g., a particular ring, a particular audible indicator, a particular visual indicator, etc.) Some embodiments provide that the circuitry 150 can receive or detect a particular audible indicator from the speaker 130 and/or the audio port 120 (e.g., an earphone/headphone jack) using a sensor in the circuitry 150. Some embodiments provide that the circuitry 150 can receive or detect electrical signals from the audio port 120 and/or the docking port 140 that are indicative of, for example, an incoming call or incoming/pending message.
The circuitry 150 receives or detects the particular indicator and generates a corresponding indicator to enhance the mobile phone's particular indicator. Some embodiments according to the present disclosure provide that the circuitry 150 will light up the LEDs 160 in a particular sequence, pattern, color, and/or intensity based on, for example, the particular indicator that is received or detected from the mobile phone 110. The beads 180 that cover the LEDs 160 can further enhance the indication generated by the mobile phone cover 100 by providing, for example, different shapes and/or colors.
Some embodiments according to the present disclosure contemplate that the mobile phone 110 uses different indicators for different callers, for different types of messages and/or for different senders of messages, for example. The different indicators (e.g., different audio indicators, different electrical signal indicators, etc.) that are received or detected by the circuitry 150 cause the mobile phone cover 100 to generate correspondingly different responses by lighting up the LEDs 160 or the LEDs 160 and the beads 180 in a respective sequence, pattern, color, shape and/or intensity. Thus, for example, an incoming phone call from a first person would cause a first pattern of LEDs 160 to light up on the mobile phone cover 100; an incoming phone call from a second person would cause a second pattern of LEDs 160 to light up on the mobile phone cover 100; an incoming text message from a particular person would cause a third pattern of LEDs 160 to light up depending on the particular person, for example; and an incoming communication from an unknown caller, perhaps indicated by a particular caller or ring tone, for example, would cause a fourth pattern of LEDs 160 to light up. These patterns can be hardwired and/or programmed in the mobile phone cover 100 and/or the mobile phone 110. Some embodiments provide that the mobile phone cover 100 and/or the mobile phone 110 are programmed with the patterns when the mobile phone cover 100 and the mobile phone 110 are connected, or when the mobile phone cover 100 and/or the mobile phone 110 are connected to a computer. Individual patterns or sets of patterns and their correspondence to various events can be set by a user and/or software and/or firmware, or can be set automatically due to default settings stored on the mobile phone cover 100 and/or the mobile phone 100.
Some embodiments according to the present disclosure contemplate that the LEDs 160 or subsets of the LEDs 160 correspond to different frequencies (e.g., different LEDs 160 correspond to different musical notes such as A, B, C sharp, D flat, etc.) and that the ring tone indicative of a particular caller or a particular type of message is played out by the different LEDs 160. The circuitry could also control particular LED intensities and duration, for example, to correspond to different types of musical notes (e.g., quarter note, eighth note, etc.) and different musical dynamics (e.g., loud, soft).
FIG. 3 illustrates an embodiment of a circuit arrangement according to the present disclosure. The circuitry 150 may include, for example, a processor 200, a memory 210 and/or a sensor 220 as illustrated in FIG. 3. The processor 200, the memory 210 and/or the sensor 220 are connected to a bus 230. The LEDs 160 are also connected to the bus 230. Although illustrated as three LEDs 160, some embodiments according to the present disclosure contemplate using more or less than three LEDs 160. In addition, some embodiments according to the present disclosure contemplate using more or less than one sensor, one processor or one memory.
The processor 200 may include, for example, one or more of the following: a general processor, a central processing unit, a digital filter, a microprocessor, a digital processor, a microcontroller, a programmable array logic device, a complex programmable logic device, a field-programmable gate array and an application specific integrated circuit, and a memory. Code, instructions, software, firmware and/or data may be stored in the processor 200 and/or the memory 210.
The memory 210 may include, for example, one or more of the following: a non-transitory memory, a non-transitory processor readable medium, a non-transitory computer readable medium, a read only memory (ROM), a random access memory (RAM), a cache, a semiconductor memory, a magnetic memory, an optical memory, a flash memory, a flash card, a compact flash card, memory cards, secure digital memory cards, a microcard, a minicard, an expansion card, a smart card, a memory stick, a multimedia card, a picture card, flash storage, a subscriber identity module (SIM) card, etc. The memory 210 may be configured to store code, instructions, software, firmware and/or data for use by the processor 200 and may be external and/or internal to the processor 200.
Some of the code, instructions, software, firmware and/or data may be hardwired (e.g., hardware implementations, hardwired into registers, etc.) and/or may be programmable according to some embodiments of the present disclosure. In some embodiments, the ringtones and lighting patterns can be controlled by an interface with the mobile phone 110 and/or the circuitry 150, or can be controlled by software stored on, for example, the mobile phone 110 and/or the memory 210. In some embodiments, the mobile phone 110 and/or the mobile phone cover 100 can be programmed when the mobile phone 110 and/or the mobile phone cover 100 are synched and/or linked with a computing device (e.g., a computer).
In operation in accordance with some embodiments, the mobile phone 110 receives an incoming call or message. The mobile phone 110 may generate a particular audio indicator (e.g., a particular ring tone) that is received by the sensor 220. The sensor 220 senses (e.g., detects and/or processes) the particular ring tone and sends one or more signals to the processor 200 based on the sensed ring tone. The processor 200 determines which of the LEDs 160 to light based on the one or more sent signals. The processor 200 may have its own LED driver circuitry, for example, with which to drive the LEDs 160.
The processor 200 may determine which LEDs 160 to light based on the one or more sent signals by accessing the memory 210. The memory 210 may include, for example, a table or other memory arrangement that stores a correspondence between the one or more sent signals (or one or more values based on the one or more sent signals) and the respective sequences, patterns, colors, and/or intensities of one or more selected LEDs 160. The processor 200 can then execute the respective sequence, patterns, colors, and/or intensities of selected LEDs 160 as set forth in memory 210.
In some embodiments, the one or more sent signals represent one or more musical notes. The memory 210 may include, for example, a table or other memory arrangement that stores a correspondence between the one or more musical notes and the respective sequence, patterns, colors, and/or intensities of one or more selected LEDs 160.
Some embodiments according to the present disclosure contemplate lighting the LEDs 160 and the beads 180 into alphanumeric patterns that convey an indicator (e.g., one or more initials of the caller) or a message.
The table or other memory arrangement can be manually programmed by a user or can be programmed automatically by the processor 200. For example, a user can manually program processor 200 and the memory 210 such that all of the LEDs 160 blink red when a particular caller calls; or the processor 200 can automatically select a preset display of LEDs 160 when a different caller calls or texts.
Some embodiments according to the present disclosure provide that mobile phone circuitry 240 is connected to the bus 230. The connection can be wired via the audio port 120 and/or the docking port 140, or the connection can be wireless from one or more antennas of the mobile phone 110, for example. The mobile phone 110 may generate a signal (e.g., electrical signal, digital signal, analog signal, data signal, wireless signal, etc.) that is an indicator (e.g., a particular ring tone) that is received by either by the sensor 220 or by the processor 200. The processor 200 can include, for example, an analog-to-digital converter. In some embodiments, the signal generated by the mobile phone 110 is received by the processor 200 which then determines in which manner to light one or more selected LEDs 160 to light based on the received signals.
FIG. 6 illustrates an embodiment according to the present disclosure in which a digital signal processor 270 is used with an analog-to-digital converter 290 and one or more LED drivers 280. Similar in some aspects to FIG. 3, FIG. 6 shows an analog-to-digital converter 290 that converts the analog input signals from the sensor 220 or the mobile phone circuitry 240 to digital input signals. The digital signal processor 270 processes the digital input signals in a similar manner as the processor 200. The digital signal processor 270 then sends out signals to the LED driver 280 which, in turn, drives the LEDs 160. There may be multiple LED drivers 280 for multiple sets of LEDs. For example, one or more LED drivers 280 can drive a set including the red LED 160a, the green LED 160b, and the blue LED 160c as illustrated in FIG. 2.
As with the processor 200, the digital signal processor 270 may include, for example, one or more of the following: a general processor, a central processing unit, a digital filter, a microprocessor, a digital processor, a microcontroller, a programmable array logic device, a complex programmable logic device, a field-programmable gate array and an application specific integrated circuit, and a memory.
FIG. 4 illustrates an embodiment of a portion of the mobile phone cover 100 according to the present disclosure. The mobile phone cover 100 includes circuitry 150 that may be, for example, embedded, at least in part, in the mobile phone cover 100. Some embodiments according to the present disclosure also contemplate that the circuitry 150 can be partially on the inside or the outside of the mobile phone cover 100. The circuitry 150 includes a circuit board, for example, that is disposed above the audio port 120. The circuit board may include, for example, a physical via through which an audio connector 250 (e.g., an earphone connector, a headphone connector, a speaker connector, a headset connector, etc.) passes to connect to the audio port 120 and the other circuitry of the mobile phone 110. The circuitry 150 is connected to the audio connector 250 and/or the audio port 120.
Some embodiments according to the present disclosure provide that, when the mobile phone 110 receives an incoming call or message, the mobile phone 110 generates an audio signal through the audio port 120 and the audio connector 250. The audio signal may represent, for example, a particular ringtone or other type of audio indicator. The audio signal may be, for example, an electrical signal, a data signal, a digital signal, an analog signal, or an audio output. The circuitry 150 can be connected to the audio port 120 and/or the audio connector 250, and can receive and/or sense the audio signal. As described above, the circuitry 150 then determines the manner in which to light one or more selected LEDs 160 based on the audio signals.
FIG. 5 illustrates an embodiment of a portion of the mobile phone cover 100 according to the present disclosure. The mobile phone cover 100 includes circuitry 150 that may be, for example, embedded, at least in part, in the mobile phone cover 100. Some embodiments according to the present disclosure also contemplate that he circuitry 150 can be partially on the inside or the outside of the mobile phone cover 100. The circuitry 150 illustrated in FIG. 5 may be in addition to or instead of the circuitry illustrated in FIG. 4. The circuitry 150 includes a circuit board, for example, that is disposed under the docking port 140. Some embodiments according to the present disclosure provide for a docking connector 260 extending from the circuit board 150 to the docking port 140. The circuit 150 is connected to the docking port 140 and/or the docking connector 260. The docking connector 260 can be attached to the circuitry 150 or can be part of the circuitry 150. In addition, the docking connector 140 can be part of a docking cable (e.g., a USB cable) that, similar to the audio connector 250 in FIG. 4, passes through a via (e.g., a physical window) in the circuit board of the circuitry 150 to connect to the docking port 140 and the circuitry of the mobile phone 110.
FIG. 7 illustrates an embodiment of a mobile phone cover 100 according to the present disclosure. The mobile phone cover 100 can use LEDs 160 for edge lighting and/or signaling. Referring to FIG. 7, the mobile phone cover 100 can be configured with a window 300 that includes LEDs 160 along the edge of the window 300. The window 300 can be a physical opening and/or a transparent portion of the mobile phone cover 100. The window 300 provides visual access to a logo 310 of the mobile phone 110. The logo 310 can be printed or attached to the mobile phone 110 or the mobile phone cover 100. The LEDs 160 are disposed in the edge of the window 300 so that, when the LEDs 160 light up, the logo 310 is illuminated. The LEDs 160 can be lit up according to different patterns, intensities, colors, etc. as is disclosed herein. In some embodiments, the edge lit LEDs 160 can point outward or inward with respect to the mobile phone 110. The edge lit LEDs 160 can be slightly raised above the surface of the mobile phone 110 and can point in a direction along an adjacent surface of the mobile phone 110.
Some embodiments provide that the LEDs 160 can be located along the edge of the mobile phone cover 100 to provide edge illumination. The LEDs 160 can be disposed in a bumper portion (e.g., a bumper band 320) of the mobile phone cover 100. The bumper band 320 can be raised on a back side and/or a front side, for example, so that the LEDs 160 are exposed. The bumper band 320 can be edge lit by the LEDs 160, for example. The number of LEDs 160 illustrated in FIG. 7 is merely exemplary. There can be more or less that the illustrated LEDs 160. For example, the LEDs 160 can be located around the periphery of the bumper band 320, or can be arranged in groups according to different lighting configurations.
In one embodiment, the LEDs 160 illustrated in FIG. 7 can direct lighting substantially in the x-direction. In another embodiment, the LEDs 160 illustrated in FIG. 6 can direct lighting substantially in the y-direction. In yet another embodiment, the LEDs 160 illustrated in FIG. 6 can direct lighting substantially in the z-direction. In some embodiments, the LEDs 160 can direct lighting substantially along the x-, y-, and/or z-direction. The direction of the lighting from the LEDs 160 can be influenced, for example, by the location and direction of the LEDs 160 as well as other influencers such as waveguides, lenses, diffusers, reflectors, prisms, and/or other optical influencers. The LEDs 160 can be lit up according to different patterns, intensities, colors, etc. as is disclosed herein.
FIG. 8 shows a cross-section of an embodiment of a mobile phone cover 100 according to the present disclosure. In this configuration, the LEDs 160 can be disposed on the front portion (illustrated) and/or the back portion (not illustrated) of the bumper band 320 disposed along the edge of the mobile phone cover 100. The LEDs 160 can be facing, for example, the y-direction using the direction convention illustrated in FIG. 7. Thus, the LEDs 160 on the front side of the bumper band 320 and the logo 310 would both face the same direction, for example.
