Abstract: A switching apparatus provides switching modules, each of which can switch a voltage from an independent power source. Additionally, the switching apparatus provides a single output for independent sources, with the single output providing a power source for a load (e.g., server). In order to dissipate thermal energy, the switching apparatus includes a heatsink that is directly coupled to the switching modules. As a result of the connection between the heatsink and the switching modules, the switching apparatus can reduce the size of the heatsink as well the number of heatsinks. In this manner, the size, footprint, and amount of material of the switching apparatus is reduced, thus reducing the cost of the switching apparatus as well as increasing the ability to provide additional switching apparatuses in a volume, such as a cabinet.

Abstract: A stringed musical instrument comprises a neck, a body and a neck joint. The neck has a heel comprising at least a wedge. Correspondingly, the body has a heel slot at a neck joint location along an upper bout of the body. The heel slot is complementary to the heel of the neck and includes a shaped pocket that corresponds with the wedge of the neck. The neck is attached to the body such that the wedge engages the shaped pocket of the heel slot and the neck is fixed to the body, e.g., using an adhesive.

Abstract: The present disclosure provides a method and system for mounting a current transformer in proximity to a circuit breaker of an electrical system. Generally, a plurality of current transformers (CTs) are provided to measure a plurality of branches from a main power supply and are accumulated on a sensor module. In at least one embodiment, the sensor module includes a molded polymer mounting support that can support the CTs. The polymer molded mounting support departs from the standard circuit board and is substantially less fragile. A wiring channel is provided within the sensor module so that CT output wiring can be safely routed to the output connector using as few as two soldered connections, rather than the typical six soldered connections required in existing branch monitoring systems. Multiple sensor modules can be stacked to allow continued alignment with the CTs and software/firmware/hardware can allow for any current polarity changes.

Abstract: The present disclosure provides a method and system for mounting a current transformer in proximity to a circuit breaker of an electrical system. Generally, a sensor assembly contains a plurality of current transformers (CTs) for measuring power wires from a main power supply. To accommodate measuring a greater number of wires than one sensor assembly can service, a plurality of sensor assemblies can be mounted end-to-end. The sensor assemblies can have symmetrical recessed portions that laterally align when mounted end-to-end by inverting one of the sensor assemblies. The lateral alignment allows CTs mounted lateral to the recessed portions to be aligned with corresponding circuit breakers, so that wires passing from the circuit breakers are aligned with the CTs, reducing bending stresses on the CTs in contrast to prior efforts. Changes in polarity caused by the inversion can be adjusted by software, firmware, hardware or a combination thereof.

Abstract: An organization system according to the present invention generally includes a plurality of reconfigurable carts that can be positioned in the storage site in a generally side-by-side configuration. At least one of the carts can be movable from the storage site to the remote location independent of the other cart. The carts can include one or more selectively positionable partitions, such that the storage space is adjustably dividable into a number of defined reconfigurable modules for separable storage of the equipment.

The carts further include wheel assemblies and a track follower mechanism. The modular storage system further includes a track positioned on the floor, the track follower being engageable with the track. The end panels have a plurality of apertures to allow air movement in the storage space allowing contents positioned in the storage space to dry when the plurality of carts are in the abutting side-by-side position.

Abstract: A modular storage system utilizes a plurality of carts. Each cart has a base with a platform, ends, sides, and end panels attached to and extending upwardly from the ends. The end panels and platform define a storage space that is accessible through one of the sides. The carts also have a truss between the end panels for hanging articles. The carts have wheel assemblies attached to and extending below the base to provide a rolling surface adapted to roll on the floor and a track follower mechanism for engaging a track in the storage facility housing the modular storage system. In one embodiment, the truss height is large enough such that when a hanger is hung from the truss, the truss height prevents the hanger from swinging through an arc greater than about twenty degrees when the modular storage unit is moved in a direction parallel to the track.

The modular storage system includes plurality of carts, each cart having a track follower mechanism that preferably is movable between a retained position and an engaged position and at least three wheels that are operably attached to and support the cart relative to the floor. The cart is retained by the track and manually movable on the wheels along the track path when the at least one track follower is selectively engaged with the track.

Abstract: An oscillator circuit includes an oscillation circuit producing a RAMP signal and at least two control signals STATE2 and STATE3, and a comparator comparing an externally produced error signal ERR with the RAMP signal. When the ERR signal is between minimum and maximum levels of the RAMP signal, the duty cycle of a PWMOUT signal of the oscillator circuit varies as a function of the difference between the ERR and RAMP signals, and preferably accounts for approximately 85% of the total period. When the ERR signal is less than or equal to the minimum level of the RAMP signal, the duty cycle of the PWMOUT signal is fixed at a first value which is preferably approximately 5% of the total duty cycle. When the ERR signal is greater than or equal to the maximum level of the RAMP signal, the duty cycle of the PWMOUT signal is fixed at a second value which is preferably approximately 90% of the total period.

Abstract: The ignition coil driver module of the present invention includes a control integrated circuit, formed of a low voltage semiconductor material, and a high current load driver integrated circuit, formed of a high voltage integrated circuit, housed within a common package. The high current load driver integrated circuit is responsive to a low voltage drive signal provided by the control integrated circuit to permit a load current to flow unrestricted through the load driver integrated circuit and an inductive load connected thereto. The control integrated circuit includes a sense resistor which receives the load current from the high current load driver integrated circuit, converts this current to a sense voltage, compares the sense voltage to a reference voltage generated within the control integrated circuit, and forces the low voltage drive signal to drop to a level which will limit the load current to a predetermined current value.
