Abstract:
A modular digital presentation switcher is a device that can convert different kinds of incoming multimedia signals into an outgoing signal in an analog and digital format. The device retrieves the incoming multimedia signals through input modules. Each of the input modules is capable of retrieving a unique signal such as composite video or S-video, VGA, and DVI-D. The device sends the outgoing signal through output modules, which are connected to the display device and the audio amplifier. A communication bus allows the input modules and the output modules to communicate with each other so that the device can cater and format the outgoing signal for the display device and the audio amplifier. An HDMI digital signal bus allows the input modules to send the outgoing signal in HDMI digital format to the output modules. A user interface module allows the user to access the functions of the device.

Abstract:
A retractable cord reel houses contacts that connect autonomously when the user aligns the spool to lock it from retracting. The spool and housing contains high quality, sensitive contacts for high speed data and other critical signals that engage when indexed by the user. The design is flexible for adaptation to a variety of applications and scalable based on cable type and length as well as the number of contacts required. The contacts are engaged when the user allows an indexing dog to engage a spool indexing housing causing the dog to shift and force a mating lever to make the electrical connection. Decoupling occurs instantly when the spool is slightly rotated by the user. The user's only action throughout the process is to pull the cable. Without this intentional action of the user, the spool, rotates freely and the contacts are not engaged.
