Abstract:
A pulse activated magnetic trip/reset mechanism for a ground fault circuit interrupter, comprising: (i) a body, (ii) a ferrite core, (iii) a plunger, (iv) a ferrite surrounding, (v) a permanent magnet, (vi) a trip/reset coil, (vii) a reset spring positioned between a plunger block and the body, (viii) a first fixed contact holder having a first fixed contact point, and (ix) a first movable contact holder having a first movable contact point, wherein the first movable contact holder is attached to the body of the plunger such that when the plunger is in its first position (trip position), the first movable contact point is not in contact with the first fixed contact point, and when the plunger is in its second position (reset position), the first movable contact point is in contact with the first fixed contact point.
Abstract:
A universal smart interface and peripheral management system for portable devices such as mobile phones. The smart system includes a connector interface that connects peripherals to a phone and/or personal digital assistant (PDA), through the smart system. The smart system includes a cradle for receiving a cell phone and interfacing the phone to external systems such as peripherals, networks and other systems through a USB hub and other suitable connector interfaces. The peripheral devices to which the smart system can interface include, but are not limited to, large displays (e.g., television), external monitors, input devices such as mice and keyboards, external storage devices, and networks (wired and/or wireless). The smart system also facilitates connectivity to large display systems such as TVs, computer displays and monitors.

Abstract:
A communications receiver architecture characterized by a relatively low intermediate frequency (IF) and a polyphase filter. The receiver includes an input amplifier coupled to a carrier signal. Respective I and Q demodulators are coupled to the output of the input amplifier. A quadrature local oscillator (LO) generator provides respective LO_I and LO_Q inputs to the I demodulator and LO_Q inputs to the I demodulator and to the Q demodulator. The quadrature LO generator is driven by a phase-locked LO, and the LO frequency is such that an IF of, in one embodiment, approximately 1 MHz results. The I demodulator and Q demodulator outputs are applied through respective AID converters to a polyphase filter. The polyphase filter outputs are then processed by a digital I/Q demodulator. Although a low IF is not generally understood to promote the image rejection performance of a receiver, substantial image rejection is afforded by the polyphase filter, thereby enabling the receiver to be realized almost entirely as a monolithic integrated semiconductor device.
Abstract:
In certain aspects, the present invention provides methods for increasing the replication capacity of influenza viruses in hens' eggs and/or cell culture, recombinant and/or reassortant influenza viruses with increased replication capacity, and immunogenic and vaccine compositions comprising such recombinant and/or reassortant influenza viruses. In other aspects, the invention further provides nucleic acids encoding influenza genes associated with increased replication capacity, expression vectors comprising the nucleic acids of the invention, methods for making influenza viruses with increased replication capacity, and kits useful for practice of the methods.
Abstract:
A method of communicating with a transceiver (120). In one arrangement, the method of communicating with the transceiver can be performed in a systemless group environment. Synchronization information (150) can be received from a mobile transceiver (110) and used to synchronize to the mobile transceiver. The synchronization information can include a timing offset and a frequency offset. Synchronization can be maintained until a predetermined condition is met, for example, a predetermined amount of group inactivity.
Abstract:
Half duplex, Frequency Hopped-Spread Spectrum wireless transceivers (102), operating without a central controller, maintain time synchronization with the frequency hopping sequence for a period after transmission of a half duplex signal ceases. The wireless transceiver (102) operates their receivers (308) according to the RF frequency hopping sequence and schedule (200). The wireless transceiver (102) is then able to send a short transmission request to signal that it will start transmitting on the Frequency Hopping schedule (200) of the previously ceased transmission. A wireless transceiver (102) that was either the original transmitter or the original receiver is able to transmit this transmission request. A subset of time slots within the hopping schedule (200) can be optionally assigned to the original transmitter and original receiver to obviate collisions of the transmit request transmissions from both device at the same time.
Abstract:
Methods, compositions and articles of manufacture involving cationic conjugated conformationally flexible polymers are provided. A method for the synthesis of cationic water-soluble polymers with linkages along the polymer main chain structure which disrupt the ability of the polymers to form extended-rod structures is provided. Such polymers may serve in the fabrication of novel optoelectronic devices and in the development of highly efficient biosensors. The invention further relates to the application of these polymers in assay methods.
