  • Patent number: 8828346
    Abstract: The present invention is directed to methods comprising adding NH3 to a SO2F2 solution to directly form a FSO2NH2 and/or a salt of [FSO2NH]?, optionally quenching any unreacted NH3 present in the resulting mixture, and isolating the product from the resulting mixture.

  • Publication number: 20140142338
    Abstract: The present invention is directed to methods comprising adding ammonia, either as an ammonium salt or as a gas at pressures below 0.01 MPa, to a sulfuryl fluoride solution to form the anion of bis(fluorosulfonyl)amine under conditions well suited for large-scale production. The bis(fluorosulfonyl)amine so produced can be isolated by methods described in the prior art, or isolated as an organic ion pair, such as an alkylammonium solid salt, or as an ionic liquid.

  • Patent number: 8653939
    Abstract: A coded wireless sensor unit has a slot sized to receive a key card. When a key card is inserted into the slot, the act of insertion generates a energy-harvested power pulse, which powers circuitry that reads electrical device control information coded on the key card and creates a first information packet signal that is transmitted by an on-board transmitter. The signal can be read by a receiver and relayed to a control unit which controls certain electrical devices which consume line power in response to received information packet signals. The control unit decodes received information packet signals and either turns on or activates the electrical devices in accordance with the decoded device control information. Removal of a key card can also be used to generate a power pulse, which creates a second information packet signal that is used to turn off or deactivate the electrical devices.

  • Patent number: 8592703
    Abstract: Tamper-resistant, longer-lasting energy-harvesting switch assemblies that can accommodate longer antennas required for operation in the 315 MHz radio frequency band are provided. In order to accommodate longer antenna that will not fit within the energy-harvesting module, the front major face of the back plate is equipped with a perimetric channel or trough into which a wire antenna can be installed. The problem of rocker wear in prior-art devices caused by abrasive action of the bows is rectified by a redesign of the rocker and the manufacture of a wear-resistant insert that snaps into place at the rear of the rocker. The potential theft problem associated with prior-art devices has been resolved by redesigning the back plate and the retainer clip that engages latches on the redesigned back plate. Non-destructive removal of the retainer clip can be effected only with a special tool.

  • Patent number: 7877073
    Abstract: A multi-channel superheterodyne receiver employs a low intermediate frequency (IF) and both high-side injection and low-side injection of a selected local oscillator (LO) signal into the mixer in order to position image frequencies outside the passband of a single image reject filter. Any channel that falls within a used portion of the image reject filter passband can be downconverted with image rejection if the utilized bandwidth portion is no greater than about 4 times the IF minus the bandwidth of a channel in the filter passband. Low side injection is used for channels falling within the lower half of the passband of the image reject filter, while high-side injection is used for channels falling within the upper half thereof. The image always remains outside the passband and the receiver can accommodate a greatly increased number of channels.

  • Publication number: 20100070100
    Abstract: A wireless control system includes at least one remote actuator unit (RAU) and at least one local sensor units (LSU) or self-powered, wireless sensor (SPWS), and may further include a wireless commissioning system (WCS), which enables associations between devices to be established from a single location. The LSUs, RAUs, and SPWSs are each programmed to operate in harmony with one another by creating associations between each other, each being identifiable by the others using a unique identification number. This association can be accomplished using programming buttons on each type of unit. Alternatively, the associations between devices within a wireless controlled system can be greatly simplified using the WCS. Establishing associations between the various devices permits the devices to interact with each other. The absence of an association between devices prevents the devices from interacting with one another. Each device can be associated with zero, one, or multiple other devices.

  • Patent number: 7554508
    Abstract: A universal frequency translation module (UFT) frequency translates an electromagnetic (EM) input signal by sampling the EM input signal according to a periodic control signal (also called an aliasing signal). By controlling the relative sampling time, the UFT module implements a relative phase shift during frequency translation. In other words, a relative phase shift can be introduced in the output signal by sampling the input signal at one point in time relative to another point in time. As such, the UFT module can be configured as an integrated frequency translator and phase-shifter. This includes the UFT module as an integrated down-converter and phase shifter, and the UFT module as an integrated up-converter and phase shifter. Applications of universal frequency translation and phase shifting include phased array antennas that utilize integrated frequency translation and phase shifting technology to steer the one or more main beams of the phased array antenna.
