Filed:

Mar 3, 2000

Appl. No.:

09/519380

Michael E. Shepperd - Lebanon IN

Assignee:

Electra Corporation - Indianapolis IN

International Classification:

H04B 116

US Classification:

455334, 455343, 455572, 455130

Abstract:

A radio includes a receiver circuit, a microprocessor, an input/output (I/O) port, at least one switch for configuring the I/O port, an audio amplifier coupled to the receiver circuit and to the I/O port, an audio frequency transducer coupled to the I/O port, and a power supply coupled to the I/O port, the receiver, the microprocessor, the at least one switch, and the audio amplifier. The at least one switch is coupled to the microprocessor. The audio frequency transducer is selectively coupled to the audio amplifier through the I/O port and the power supply is selectively coupled to the I/O port to permit activation of the audio frequency transducer by a signal coupled from the audio amplifier through the I/O port and to provide access to the power supply through the I/O port.

International Classification:

B66F001/00

US Classification:

414592000

Abstract:

A high lift material handling attachment for vehicles such as tractors, riding mowers, garden tractors, golf carts all terrain vehicles etc. wherein the material handling attachment may be front or rear mounted and vertical lifting power provided by a self contained power source or powered from the tractor etcs. own power source. A frame supports the vertical lift post and drive assembly that powers a movable trolley, which maybe fitted with a pitchfork assembly, flat platform, bucket, or other implement. The trolley attachment points allows variations such as rotating the forks 180 degrees, and lock their positions to about vertical. The fork can now be raised or lowered, by the operating persons control, and then used as a “rake” to move materials such as hay and straw away from walls etc., raked into a pile and ready to lift and transport. A flat platform may also be easily attached to transport and lower loads—such as sliding a bag of animal feed from a truck bed onto the platform and then transported where the load can be raised or lowered to a storage area.

Assignee:

General Aviation Electronics, Inc. - Indianapolis IN

International Classification:

H04B 138

US Classification:

455 89

Abstract:

A portable transceiver includes a two-piece transceiver housing which encloses a double-sided printed circuit board. The transceiver housing includes a front surface portion and a control panel portion which is integral with, but recessed below, the front surface portion. Within the control panel portion are four clearance apertures which provide operator access to the operator controls of the printed circuit board. The width and depth of the housing are suitably sized to enable the portable transceiver to be hand held in one hand while the thumb of that same hand is able to manipulate the various operator controls. These controls protrude through the various clearance apertures yet the outermost portions of the controls remain flush with to recessed below the front surface portion. The printed circuit board is a self-contained transceiver such that all wiring is completed prior to installing the printed circuit board into the transceiver housing.

International Classification:

H04B 140

US Classification:

325 21

Abstract:

A network for connecting a receiver and a transmitter to a common antenna to utilize the antenna for both transmit and receive modes of operation is disclosed, which network is suitable for either relay antenna switching or solid state antenna switching. The network includes a band pass filter coupling the transmitter output to the antenna at least during the transmit mode of operation and first and second filter junction points for coupling the antenna to the receiver. One of the first and second junction points is coupled to the receiver at least during the receive mode of operation, and includes means for inhibiting the application of the transmitter output signal to the receiver during the transmit mode of operation. When the circuit employs an antenna switching relay, this relay, typically a single pole double-throw relay, has normally closed contacts coupling the second filter junction point to the receiver, and normally open contacts closable to complete the coupling of the transmitter output to the antenna only in the transmit mode of operation. When the network is employed for solid state antenna switching, the band pass filter continuously couples the transmitter output to the antenna and the first filter junction point includes a further filtering arrangement, the frequency characteristics of which are variable with the mode of operation to allow receipt of incoming signals in the receive mode, while inhibiting the application of transmitted signals to the receiver in the transmit mode.
