Abstract: An encoder/decoder for an emergency alert system to enable broadcasters to receive, store, re-broadcast and originate emergency alert messages. Multiple emergency alert signals are received by the encoder/decoder. A digital signal processor of the encoder/decoder scans the reception of the multiple emergency alert messages to determine the presence of an incoming emergency alert signal. The digital signal processor provides digital implementation of a frequency shift key modulation and a frequency shift key demodulation to encode and decode emergency alert messages. Additionally, the digital signal processor functions as a central processing unit to control input/output ports over a digital signal processor bus for performing all encoding and decoding functions and to control all encoding and decoding functions.

The tray has a receptacle and contained within the receptacle of the tray is a layer of liquid adhesive. Disposed on the layer of liquid adhesive within the receptacle is a layer of bait material which adheres to the layer of liquid adhesive. Vessel walls are cut away to form ramps and openings for pests to travel over the ramps through the openings and into the bait chamber. The tray containing the bait and liquid adhesive is packaged for placement in the bait chamber with a thin film disposed over the tray. Before the tray with the bait and liquid adhesive is placed in the bait chamber, the thin film is removed from the tray.
Abstract: An emergency alert communication system comprising a radio frequency receiver. The radio frequency receiver decodes incoming emergency alert signals and demodulates data header signals and emergency alert voice message signals of the emergency alert signals. Included in the data header signals are event and location code signals, which are followed by the emergency alert voice message signals. The demodulated data header signals in the form of digital data header signals are applied to a microcontroller. A telephone keypad of a telephone device is actuated to enter into the microcontroller event and location code signals. Should the event and location code signals demodulated by the receiver and applied to the microcontroller match the event and location code signals entered into the microcontroller by the telephone keypad, the microcontroller routes through an audio switching circuit the emergency alert voice message signals to a speaker, a recording device and a telephone handset of a telephone device.

Abstract: A multiple address radio network in which there is a central station and remote radio sites. The central station transmits control and data acquisition signals to the radios at the remote radio sites and the radios at the remote radio sites transmit to the central station acquired data. Each remote radio has an automatic frequency calibration circuit for adjusting its associated remote radio to reduce frequency offset between the radio frequency carrier transmitted by the remote radio and the radio frequency carrier transmitted by the central station by adjusting the temperature compensated crystal oscillator of the automatic frequency calibration circuit. Toward this end, a microprocessor of the frequency calibration circuit detects and measures the offset frequency and controls a digital potentiometer for adjusting the temperature compensated crystal oscillator.
Abstract: A bulk material container comprises a discharge opening defined by a discharge assembly. A sliding gate overlays the discharge opening for preventing bulk material to advance through the discharge assembly. The sliding gate is withdrawn from the position overlaying the discharge opening to discharge material from the bulk material container through the discharge assembly into a hopper. A closure seal surrounds the discharge opening. When the sliding gate is disposed over the discharge opening, cam assemblies raise the sliding gate into compressive sealing engagement with the closure seal. When the cam assemblies lower the sliding gate, the sliding gate is withdrawn from the discharge assembly. Wipers mounted on the discharge assembly remain in contact with the sliding gate to remove bulk material that may remain on the sliding gate while the sliding gate is withdrawn from the discharge assembly.
Abstract: A snail bait holder and snail trap comprising a vessel and a cover which form a snail bait holding chamber. Disposed within the vessel is a laminated disc for supporting the snail bait. An upper layer of the laminated disc is made of a liquid absorbent material on which is deposited a slurry of snail bait. A lower layer of the laminated disc is made of a non-absorbent, flexible material so that mounds of snail bait are disposed on the upper layer. The vessel has an upwardly directed wall which is cut out to form openings. The cut out sections of the wall are bent outwardly and downwardly to form ramp over which a snail travels to enter the snail bait holding chamber.
Abstract: A portable, thermally insulated container having an isothermal chamber for storing temperature sensitive material. An electronic circuit activates a heater when the temperature in the chamber is below a preselected magnitude and activates a Peltier heat pump to cool the chamber when the temperature in the chamber is above a preselected magnitude. The electronic circuit operates a fan for the intake of air into the chamber while the Peltier heat pump is operating and discontinues the operation of the fan while the heater is operating. Included in the electronic circuit are two sets of dual operational amplifiers. A temperature sensor responsive to the temperature in the chamber controls the operation of one set of dual operational amplifiers for operating the Peltier heat pump to cool the chamber and controls the operation of the other set of dual operational amplifiers to heat the chamber.
