Abstract: Disclosed are various embodiments of an input signal combiner. In one embodiment, a receive stage receives a multi-phase waveform and separates the multi-phase waveform into a plurality of waveforms. Analog-to-digital converters convert the plurality of analog waveforms into at least one digital signal. At least one gain stage adjusts an amplitude of each of the digital signals and combines the amplitude adjusted digital signals into at least one gain adjusted combined signal. A signal extraction stage extracts an inbound signal from the at least one gain adjusted combined signal according to a demodulation scheme.

Abstract: Disclosed are various embodiments of systems and methods for relative phase shift keying. In one embodiment, an analog waveform is converted to digital signals. A specified frequency range is isolated and the magnitudes of tones corresponding to a channel are measured. The relative phase of a subset of the tones having the greatest magnitude is measured and a relative phase component is generated. At least one symbol is associated with the subset of tones and the relative phase component.

Abstract: Disclosed are various embodiments of a programmable slicer in a digital signal processing system and/or software radio system. In one embodiment, a plurality of demodulation schemes and a plurality of channel definitions are stored in a channel allocation table. An analog waveform is received and converted into at least one digital waveform. A specified frequency range is isolated from the at least one digital waveform. The magnitude of tones within the specified frequency range is measured and stored in a signal magnitude table. Symbols and/or bits are decoded from the signal magnitude table by applying a demodulation schemes and channel definitions to the magnitudes stored in the signal magnitude table.

Abstract: A system for controlling remotely located electrically-powered systems in an electrical network includes a first transceiver. The first transceiver has an identifier in memory and wirelessly communicates bidirectionally with a control center via a plurality of additional wireless birdirectional transceivers. At least one of the plurality of additional wireless bidirectional transceivers is a site controller coupled to a wide area network. At least another of the additional wireless bidirectional transceivers is coupled to a meter. A microcontroller is coupled to the first transceiver and to a remotely located electrically-powered system. The microcontroller controls operation of the electrically-powered device from at least a state of powered on to a state of powered off when a signal associated with actuating the power state of the remotely located electrically-powered system is received. A keypad containing user selectable buttons is coupled to the microcontroller for receiving user input.

Abstract: An animal call rotating device that allows the user hands free manipulation of the calling device, thereby allowing the user to use both hands to hold and operate a weapon, camera, or other device. The holder can be secured to any part of a hunting stand, frame, shelter, or device.

Abstract: A system for providing remote monitoring of electricity consumption is provided. In one embodiment the system may comprise electric meters, communication devices having a unique address and defining a wireless communication network, and a site controller. Each electric meter may be configured to measure electricity consumption of a load. Each communication device may be associated with one of the electric meters and configured to receive electricity consumption data and generate a transmit message using a predefined communication protocol being implemented by the wireless communication network. The transmit message may comprise the unique identifier and electricity consumption data.

Abstract: A portable hunting device for elevating a hunter wherein the device can be transported to and from a hunting site on a transport vehicle. When fully assembled, the hunting platform is supported by a ladder and at least two support legs. During transport the hunting platform is lowered, the ladder is folded and the support legs are removed and stored in a storage position so that the device is compact for safe transportation. Upon arrival at the desired location, the ladder is extended from a folded position to an extended position and the legs are removed from the storage position and are inserted into the leg guides where the legs are locked into position to prevent separation. A cable is connected from a hand-operated winch to the ladder so that as the winch is rotated, the ladder is rotated and the platform is raised from the transport position to the hunting position.
