Abstract: Techniques that relate to selecting content for playback are disclosed in various implementations. The techniques may include receiving, at a computing device and from a primary electronic content source, a first input signal for playback by a presentation device. The techniques may also include analyzing information that is indicative of content represented by the first input signal to determine whether the first input signal is intended for playback by the presentation device. The techniques may also include causing the presentation device to play back a second input signal from a backup electronic content source in response to determining that the first input signal is not intended for playback by the presentation device.

Abstract: Error detection systems and methods are provided. An error detection system (100) can include a plurality of networked output devices (110) and a processor (130) coupled via a network (120) to the plurality of output devices. The processor can be configured to aggregate output data (135) from at least a portion of a plurality of parallel, networked, output devices. The processor can be further configured to compare (140) the aggregated output data with an output data sample selected from one of the plurality of output devices and detect (145) a discrepancy between the output data sample and the aggregated output data. The processor can also be configured to compare (150) the detected discrepancy to a predetermined threshold and signal (155) when the detected discrepancy exceeds the predetermined threshold.

Abstract: Digital signage transaction systems and methods are therefore provided. An illustrative transaction method can include accessing, via a computing device, a plurality of digital sign files disposed within a repository. The transaction method can further include communicating at least one external selection criterion to the computing device. Responsive to the at least one external selection criterion, selecting at least a portion of the digital sign data files and communicating at least one of the portion of selected digital sign files from the repository to a display device.

Abstract: Systems, methods, and other embodiments associated with providing uninterrupted electrical power and data communications are described. One example method includes detecting primary electrical power loss to a network switch, and/or a loss of wired Internet connectivity to the network switch. The example method may also include controlling a backup power source to provide secondary electrical power to the network switch, and controlling a wireless access point to provide wireless Internet connectivity to the network switch.

Abstract: A file management system (22) and method intercept a request to access a main memory to run a file and redirect the request to a memory location other than the main memory.

Abstract: Disclosed embodiments relate to a method for opening a cash safe secured with a circuit. For example, the method may comprise receiving a key by a circuit connected to a locking mechanism for securing a cash safe closed and retrieving, by the circuit, a stored key. The method may further comprise comparing, by the circuit, the received key to the stored key, determining, by the circuit, whether to release the cash safe based on the comparison, and sending, by the circuit, a signal to release the locking mechanism securing the cash safe closed if determined to release the cash safe.

Abstract: A method including transferring a device ID through a first communication channel between a device and a transaction device, configuring the device to send secured information in response to receiving a transaction request and sending user information to a service provider through a second communication channel in response to receiving a request to authenticate the secured information.

Abstract: A system and method for enhancing operability of client-server computing system is herein disclosed. A system includes a first computing device. The first computing device includes a file type association module. The file type association module determines, as part of a remote computing session, whether to associate a file type with an application program on the first computing device or an application program on a second computing device. The file type association module causes the file type to associate with the application program on one of the first and second computing devices.

Abstract: In one embodiment, a computer system comprises a multicast node to receive a multicast signal indicating a multicast content, in response to the multicast signal, apply a multicast notification signal to at least one remote client managed by the remote computing server, receive, from the at least one remote client, a subscription signal indicating that the at least one remote client subscribes to the multicast content, and in response to the subscription signal, connect the at least one remote client to the multicast node on the remote computing server, whereby the at least one remote client accesses the multicast content.

Abstract: A computer system having first and second low power states includes a controller (such as a BIOS routine) that can generate a request to transition to the first low power state (e.g., Suspend state defined in the Advanced Power Management or APM. Standard) in response to activation of predefined events (e.g., a time-out event or a user-initiated event). A program receiving the request can deny the request and instead causes the system to transition to a second low power state (e.g., the APM Standby state).

Abstract: A method for aiding use of a computer includes receiving a home base signal, and in response to the home base signal, transferring control of the computer to a user home base application.

Abstract: The invention is a computer interface with a hardwired button array on the computer chassis for simulating the apparatus of common consumer electronic devices. Each button of the array of buttons is connected to at least two wires, with the depression of a button causing an electrical connection between the corresponding two wires. The voltage on one of these wires is forced to a steady-state logic low, while the voltage on the other wire is allowed to float electrically free. Nonetheless, the second wire is at a steady-state high voltage due to that wire's connection through a pull-up resistor to a voltage source. Upon electrical connection, the wire that is floating free acquires a logic low voltage. In response, a line state detector sends an interrupt signal to a microprocessor, which transitions the voltage on the wires forced to a steady-state logic low from a logic low to a free floating state.

Abstract: The invention is a computer system with a button array on the computer chassis for simulating the operation of common consumer electronic devices. Each button of the array of buttons is hardwired to the system processor. Upon activation of one of these buttons, an interrupt signal is sent to the system processor. The system processor halts whatever it is doing, and subsequently identifies the activated button. A signal generator attached to the buttons then sends the system processor a second interrupt signal, such that upon exiting the handling of the first interrupt, the system processor is presented with a second interrupt. The system processor then handles the second interrupt. While handling this second interrupt, the system processor executes whatever function corresponds to the activated button. The system processor then exits the handling of the second interrupt and resumes whatever activity it was engaged in before the activation of the button.
