Abstract: A variable load circuit for adjusting a phase of a differential signal including a first transistor having a first terminal adapted to receive a first component of the differential signal, a second transistor having a first terminal adapted to receive a second component of the differential signal and a second terminal coupled to a second terminal of the first transistor, and a variable current source coupled to a third terminal of both the first and second transistors. The variable current source generates a bias current based on a control signal. For each of the first and second transistors, a first capacitance is created between the first and second terminals, and a second capacitance is created between the first and third terminals. The first and second capacitances are each a function of the bias current and thus the control signal and operate to adjust the phase of the differential signal.

Abstract: The present invention is a differential transconductance amplifier circuit that includes matched cross-coupled transconductance elements connected such that the differential gain of the amplifier is determined by only passive elements. By virtually eliminating the effects of active elements on the amplifier gain, the amplifier operates in a very linear manner over its entire operating range. Power consumption, amplifier noise level, and dynamic range can be optimized with appropriate selection of the passive elements that determine amplifier gain.

The gateway includes a wired communication network interface structured to communicate with at least one of the network protectors, the sensors or the devices, a first wireless communication network interface structured to wirelessly communicate with at least one of the network protectors, the sensors or the devices, and a plurality of second wireless communication network interfaces structured to wirelessly communicate with the wirelessly communicating user interfaces. A processor is operatively associated with the wired communication network interface, the first wireless communication network interface and the second wireless communication network interfaces, and is structured to pass data, information and commands between the various interfaces.

Abstract: A dampening apparatus has a housing with a plurality of first guide members and a plurality of second guide members coupled together. A first biasing member is located in an area proximate to the first guide members and within the housing. A first planar member is provided having a plurality of first apertures with the first guide members or the second guide members passing through the first apertures. A plurality of second planar members is provided having a plurality of second apertures with the second guide members passing through the second apertures. A plurality of second biasing members is located in an area proximate to the second guide members. An elongated shaft is coupled to the first planar member. The dampening apparatus could be included in a circuit interrupter.

Abstract: A digital storage memory module (200) comprises a housing (201) having a first memory (202) and a second memory (205) disposed therein. In one embodiment the first memory comprises, for example, a hot-swappable cinematic media content disk drive and the second memory comprises, for example, a flash memory. In one embodiment these two memories, though sharing a common housing, are communicatively isolated from one another. In one embodiment this digital storage memory module further comprises a first and second memory interface (203 and 209) that couple, respectively, to the first and second memory and that are accessible external to the housing such that cinematic media content can be uploaded to and downloaded from the first memory and performance information regarding the first memory can be uploaded to and downloaded from the second memory.

Abstract: A power distribution monitoring system includes a wireless gateway/controller, a network protector subnetwork including a plurality of network protectors and a portable electronic device having wireless communication functionality. Each of the network protectors is in electronic communication with the wireless gateway/controller. The wireless gateway/controller receives data from one or more of the network protectors, and wirelessly transmits at least a portion of the data to the portable electronic device. Also, a method of monitoring a power distribution system including receiving data at a first location from a network protector subnetwork that includes a plurality of network protectors, wirelessly transmitting at least a portion of the data from the first location, and wirelessly receiving the at least a portion of the data at a second location separate from the first location.

Abstract: A network protector that includes an enclosure, a frame assembly, a plurality of electrical components, including a circuit breaker, and an arc path assembly. The frame assembly is disposed within said enclosure. The plurality of electrical components is coupled to the frame assembly. The circuit breaker has at least one set of main contacts and at least one are chute associated with set of main contacts. The arc path assembly has a hollow member having at least one open end. The hollow member in fluid communication with the arc chute and the hollow member open end extends beyond said frame assembly. Thus, arc gasses traveling from the arc chute through the hollow member are exhausted into said enclosure.

Abstract: An elegantly simple bicycle storage rack that can be mounted or demounted quickly and easily from the cargo area of pick-up trucks. The rack is comprised of a lower tubular base and an upper tubular member joined by a plurality of upright posts spaced by slots for bicycle wheels. The lower tubular base fits comfortably in the foremost corner of the cargo area of the pick-up truck. The upper tubular member is secured to the sides of the pick-up truck with straps, cords or wires. A bicycle is held securely in the rack by a c-shaped hook or clamp that fits around the steering neck, frame of bicycle frame mounting and is secured with a specially designed locknut. No additional, straps, nuts, locks or other devices are needed to securely hold the bicycle in the rack. The bicycle storage rack is also constructed to be easily mounted on a surface platform when not in use in the back of a pick-up truck.
