Abstract:
The present disclosure provides techniques for an improved switching module for voltage regulators or transformers with voltage regulating taps. The switching module disclosed herein includes a first bypass switch and a second bypass switch coupled to the first bypass switch, at least one prime mover coupled to and configured to actuate at least one of the first bypass switch and the second bypass switch, and at least one load breaking switch coupled between the first and second bypass switches. In certain example embodiments, a separate prime move is configured to actuate each of the bypass switches and the load breaking switch. In certain other example embodiments, one or more of the bypass switches and the load breaking switch is actuated by a shared prime mover.
Abstract:
An electrical system that includes an enclosure and a power source located outside the enclosure and generating a first current. The electrical system can also include a transmitting inductor located within the enclosure and electrically connected to the power source, where the first current generated by the power source flows through the transmitting inductor. The electrical system can further include a receiving inductor positioned proximate to the transmitting inductor within the enclosure, where the first current flowing through the transmitting inductor induces a second current to flow through the receiving inductor. The electrical system can also include a device located within the enclosure and electrically connected to the receiving inductor, wherein the second current induced in the receiving conductor powers the device.
Abstract:
A cable management device is disclosed. The cable management device includes a first component and a second component, each component having a spooling portion to receive a cable, a flange extending from the spooling portion to maintain the cable on the spooling portion, and a coupling feature operable to facilitate coupling of the first component and the second component. The first component and the second component are configured to interface with one another such that the respective spooling portions mate to form a spool for the cable.
Abstract:
A lighting system can comprise an array of domed light emitting diodes covering a surface area of a substrate and two optics for processing emitted light. The first optic can comprise an inner surface facing the array and an exterior surface facing away from the array. The second optic can comprise grooves extending away from the array. The inner surface of the first optic can form a cavity that is large relative to the array. For example, the cavity can have a volume exceeding the volume of a cube, where each side of the cube has the surface area of the array.
Abstract:
An electrical system includes an enclosure having at least one enclosure wall forming a cavity that is environmentally sealed. The electrical system can also include a capacitor bank having at least one capacitor and at least one fuse positioned within the cavity of the enclosure. The electrical system can further include an insulating medium disposed within the cavity and in contact with at least a portion of the capacitor bank.
Abstract:
Propagation of software updates in a wireless mesh network is handled according to an "informed push" model. Nodes are given the software update that they need, but this is done in response to a sequence of propagating reports on the need for the upgrade ( i.e. , that node devices have old versions). Each node device executes a reporting cycle in which a report is sent to its neighbors that indicates the types and versions of software items that reside on the device; and for non-resident software items, the lowest versions of which the node device received knowledge from its neighbors. If a node device determines that its reporting neighbor has an old version of a software item and the node device contains a newer version of that software type residing locally, then it sends its neighbor the upgrade. Otherwise, the node "gossips" about the old version to its own neighbors.
Abstract:
An enclosure system that can include a hazardous location, enclosure having at least one wall forming a cavity. The enclosure system can also include a temperature- sensitive component, positioned within the cavity. The enclosure system can further include a measuring device configured to measure a temperature within the cavity of the hazardous location enclosure. 'The enclosure system can also include a climate control device configured to change the temperature within the cavity. The enclosure system can further include a controller operatively coupled to the climate control device and the measuring device,, where the controller controls the climate control device to change the temperature within the cavity of the hazardous location enclosure.
Abstract:
Communication apparatus and associated method for sending messages while concealing the messages among chaff data. In sending outgoing communications to and from a remote device, a stream of chaffing data is generated. A message to be communicated is inserted into the stream of chaffing data such that the beginning and ending boundaries of the first message are concealed by the chaffing data. A matching pair of deterministic number generators, one at the sending end and one at the remote device, are initialized using a common initialization value to cause generation of a common sequence of numbers with the remote device. The stream of chaffing data, or data associated with the first message, or both, are encoded with the common sequence of numbers.
Abstract:
A squid connector is described herein and can include a top portion and a bottom portion. The top portion can include a top housing having a top aperture and a top wall defining a top cavity. The top portion can also include a number of conductor receivers mechanically coupled to the top wall, and a top coupling feature disposed on the top housing. The bottom portion can include a bottom housing having a bottom aperture and a bottom wall defining a bottom cavity. The bottom portion can also include a number of fuse holders positioned within the bottom cavity, and a number of fuses remove-ably coupled to the fuse holders and a collector electrically coupled to the bottom end of the fuses. The bottom portion can also include a connector pin electrically coupled to the collector and a bottom coupling feature disposed on the bottom housing.
Abstract:
A conductor receiver is described herein for engaging a conductor. The conductor receiver can include a stationary portion for receiving and securing a bottom portion of die conductor. The conductor receiver can also include a movable portion that is coupled to the stationary portion and has an open position and a closed position. When the movable portion is in the closed position, the movable portion secures a top portion of the conductor. The conductor receiver can also have a channel with a number of rows positioned width-wise within the channel. Each row has at least one member made of conductive material, where each member has a normal position and a retracted position. When the conductor is positioned within the channel, each.member is in the retracted position.
