An ergonomic stringed instrument is described, presenting a novel ergonomic design incorporating one or more of an angled waist, provided as part of the waist portion of the stringed instrument bowl or body, and a contoured ridge, provided along at least a portion of the back of the stringed instrument bowl or body. The angled waist is provided on the treble side of the stringed instrument, which side may rest on the leg of a performer, and is configured with an angled contour towards the back of the stringed instrument. The contoured ridge runs along at least a portion of the bass side of the stringed instrument back and defines at least a slightly concave portion on the treble side of the contoured ridge.

Enclosed re-programmable non-volatile memory cards include at least two sets of electrical contacts to which the internal memory is connected. The two sets of contacts have different patterns, preferably in accordance with two different contact standards such as a memory card standard and that of the Universal Serial Bus (USB). One memory card standard that can be followed is that of the Secure Digital (SD) card. The cards can thus be used with different hosts that are compatible with one set of contacts but not the other. A sleeve that is moveable by hand may be included to expose the set of contacts being used.

A method and system are described for distributing at least one clock signal between shelves in a multi-shelf modular computing system includes a clock signal generator for generating a first clock signal, an inter-shelf bus for carrying the first clock signal to a second shelf, and a first shelf manager module, associated with the second shelf, for receiving and regenerating the first clock signal and providing the regenerated first clock signal to at least one module within the second shelf. A system and method for detecting a location of a fault in an inter-shelf bus in a multi-shelf modular computing system is also disclosed. A power source applies a bias between at least two conductors of the inter-shelf bus. At least one module detects the applied bias to determine if a fault is located between the at least one shelf and the power source.

A programmable logic device (PLD) in a microprocessor system is programmed with minimal load on system resources. A microprocessor reads programming data from a first memory using a parallel bussed interface and writes the programming data to a programming hardware assist engine using the parallel bussed interface. The programming hardware assist engine directs a portion of the programming data to a specified serial interface signal, and outputs a serial bit stream from the programming hardware assist engine to a serial programming interface of the PLD using the specified serial interface signal.

A system and method for configuring a software defined radio is disclosed. In an embodiment, a smart card and smart card reader are used to access layered information pre-programmed into a software defined radio. The smartcard reader extracts configuration information from the smart card and the configuration information is used to configure the software defined radio. The configuration may include, communication protocols, modulation/demodulation techniques, digital processing protocols, coding/decoding techniques, security authorization; operational protocols, and other information. Individual users may be given different levels of access depending on, among other things, the user's service requirements, mission requirements, security clearance, and/or authorization level. The disclosed systems and methods significantly reduce the amount of time and training required for personnel to establish communications using a software defined radio.

In a digital video system, high availability distribution is provided using spare modules such as an integrated receiver decoder, multimedia transcoder and streaming module in support of the primary modules. The primary modules multicast status messages which are monitored by the spare modules. When failure of a primary module is detected, the spare module takes over the role of the failed module, for example by joining the same multicast groups as the failed module and taking over processing of the streams of the failed module. Multiple redundancy schemes are described.

Methods and systems for distributing messages of a ring-topology-based link level communications protocol over a star-topology using a star-topology-based link level communications protocol are disclosed. According to one method, when a packet of the ring-topology-based link level communications protocol is received, it is determined whether the packet is to be sent to a number of destinations and returned to a sender. If the packet is intended for distribution to a number of destinations and return to the sender, the packet is encapsulated in a frame of the star-topology-based link level communications protocol, the destination address in the frame is set to a next destination address in a virtual ring topology, the frame is forwarded to a switch. The switch forwards the packet to the next destination in the virtual ring based on the input port and the destination address of the star-topology-based link level communications protocol. The process continues until the packet reaches the last destination in the virtual ring where the packet is encapsulated in a frame of the star-topology-based link level communications protocol and returned to the sender.

Methods for a multiple die package for integrated circuits are disclosed. An insulator layer is provided and one or more vias are formed within it. The insulator may be provided without vias, and vias formed later. At least one integrated circuit is provided and electrically coupled to at least one lead of a first leadframe overlying one surface of the insulator. At least one second integrated circuit is provided and electrically coupled to a second leadframe overlying a second surface of the insulator. Electrical connections between the two leadframes and the first and second integrated circuits are made through the insulator at selected locations, by coupling at least one lead of the first and second leadframes one to another. The leads of the first and second leadframe may be physically coupled by a welding process within vias in the insulator. A method for a removable storage card is also described.
