Abstract:
Methods and products for activating a backpack audio-visual system are generally described. In an example, a module in the backpack may detect a presence of a device in a first compartment that may be defined by a first set of walls. In response to the detection, the module may determine a status of a first speaker and a second speaker. The first and second speakers may be inside of a second compartment and a third compartment, respectively. The second and third compartments may be defined by a second and a third set of walls, respectively. Based on the presence of the device in the first compartment and the status of the first and second speakers, the module may establish a wireless communication link between the device and the first and second speakers. The backpack audio-visual system may be activated in response to the establishment of the wireless communication link.

In some examples, wire  202  may be a bus such as a universal serial bus (USB) configured to facilitate transmission of data and/or signals between module  124  and device  140 . 
         [0025]    In the example, when device  140  is inside of pocket  120 , user  150  may view device  140  through window  122  of pocket  120 . Control unit  230  may detect whether device  140  is inside of pocket  120  such as by determining whether power is being output by power unit  232  to wire  202 . In response to a presence of device  140  in pocket  120 , control unit  230  may determine a status of a communication unit, such as a BLUETOOTH module, of device  140 . If the communication unit of  140  is activated, control unit  230  may further determine a status of speaker  130 . Control unit  230  may determine whether power is being output by power unit  232  to wire  200 . Control unit  230  may send an instruction  300  to power unit  232  to activate speaker  130  if a status of speaker  130  shows that speaker  130  is deactivated. When speaker  130  is activated, communication unit  220  may be activated and speaker  130  may be in a discoverable mode. When both the communication unit of device  140  and communication unit  220  of speaker  130  are activated, a communication link  310  may be established. When both the communication unit of device  140  and communication unit  220  of speaker  130  are BLUETOOTH modules, communication link  310  may be a wireless communication link based on the BLUETOOTH communication protocol. In response to the establishment of communication link  310 , an audio-visual system comprising device  140 , module  124 , speaker  130 , and/or speaker  131  may be activated. In some examples, product  100  may use BLUETOOTH communication to communicate with a nearby phone. With use of the BLUETOOTH communication, a user may be able to handle a telephone call such as through a microphone and speaker  130 . A user may be able to use user interface  240  to skip music tracks such as utilizing fast forward and rewind features. 
         [0026]    In an example, in response to the determination of status communication unit  220  of speaker  130 , control unit  230  may send a signal  302  to indictor unit  236 . Signal  302  may be signal effective to indicate the status communication unit  220  of speaker  130 . Indicator unit  236  may be configured to be in communication with at least an indicator  320  and an indicator  322  on a surface of product  100 , such as front surface  101 , or a surface of a compartment such as compartment  112 . Indicators  320 ,  322  may be light emitting diodes (LEDs). In an example, control unit  230  may send signal  302  to indicator unit  236  to indicate that communication unit  220  of speaker  130  is activated. In response to receipt of signal  302 , indicator unit  236  may instruct an indicator among indicators  320 ,  322  to show the status indicated by signal  302  such as by issuing a binary signal to the indicator. 
         [0027]    In some examples, product  100  may further include more than one LED on at least a surface of product  100 . User  150  may instruct module  124 , such as by providing input  250  to module  124 , to activate the LEDs in order to enhance visibility on product  100  in a situation with low visibility such as night time. 
         [0028]    In some examples, compartment  110  and/or compartment  116  may include materials effective to add and/or modify functionality of product  100 . For example, compartment  116  may include insulated materials effective to regulate temperature within compartment  116 . User  150  may insert temperature sensitive objects, such as food or medication, in compartment  116  to avoid disintegration of the temperature sensitive objects. 
         [0029]    Among other possible benefits, the product in accordance with the disclosure may benefit a user by providing a computing device traveling kit product which includes numerous functions. The user may use the product to charge a computing device while the user is traveling. The user may use the product to listen to music by the computing device through wireless speakers of the product. The wireless speakers of the product may provide a convenient method to connect the computing device with the speakers when the user desires to listen to music or hear audio of a movie when the device is inside of the traveling kit product.
