Abstract: A fruit harvesting apparatus is provided which includes a vehicle, a mechanism for moving the vehicle along the ground; a tray, coupled to the vehicle, for receiving picked fruit; a pivotable hopper, mounted to the vehicle, for temporarily storing the picked fruit; and a transfer system for transferring the picked fruit from the tray to the hopper. The apparatus further includes an elevator for selectively elevating the device and/or a titling device for selectively tilting the device.

Abstract: A harvesting apparatus and method includes a vehicle designed for operation along aisles between rows of low density young citrus trees for collecting, storing and transporting citrus fruit harvested by multiple workers moving along in front of the vehicle. The apparatus and method is more efficient and cost effective for harvesting citrus fruit from low density young citrus trees and eliminates pallet tubs and the vehicle boom required to empty and replace the tubs as used in the "conventional harvesting method". The machine and method includes a large semi-circular tray preferably mounted at a level about two feet above the ground on the front of a self-propelled vehicle carrying a hopper. The tray is selectively removable to allow a tray of different size to be mounted on the vehicle to meet the harvesting conditions involved at given citrus groves.

Abstract: A removable alternating current measuring circuit provides for measuring radio frequency currents produced in an AM transmitter-antenna system without draining any power from the system. A transformer couples the transmitter-antenna system with the current measuring circuit, which includes a first and second half wave circuits for operation during the positive and negative half cycles of alternating current. During the positive half cycle, a first diode directs current through a first load resistor and through a series combination including a second load resistor and a direct current meter. During the negative half cycle, a second diode in opposition to the first diode directs current through the second load resistor and through a series combination including the first load resistor and the current meter. Current always flows through the meter in the same direction.

Abstract: Digital apparatus for generating a continuous signal waveform of a given carrier frequency fc. The apparatus comprises address circuit for generating repetitively a set of Z address signals and a memory in the form of a ROM for storing a set of Z digital values. The Z digital values define M number of cycles of the signal waveform, where M is a whole number. Each cycle of the signal waveform is defined by at least Y digital values, where Y is greater than 2. The carrier frequency fc is equal to the product of Y and M. The ROM is responsive to the address signals for repetitively reading out frm the ROM the Z digital values, whereby the continuous signal waveform is generated without discontinuity.

Abstract: A stereophonic transmitting system is disclosed for transmitting in quadrature a single carrier signal carrying first and second signals. The transmitting system comprises a phase shifter or modulator for phase shifting a carrier signal of a frequency fc in accordance with a feedback signal to provide a phase shifted carrier signal. A first detector operates to detect a component of the phase modulated carrier signal in phase with the carrier signal to provide an in-phase signal and a second detector to detect a component of the phase modulated carrier signal out-of-phase with the carrier signal to provide a quadrature signal. A first multiplier multiplies the in-phase signal by the first signal to provide a first multiplied signal and a second multiplier multiplies the quadrature signal by the second signal to provide a second multiplied signal. A difference circuit is provided for obtaining the difference between the first and second multiplied signals to provide the feedback signal to the phase shifter.

Abstract: A method and apparatus is disclosed for the remote display of percentage modulation data obtained at a transmitter site. A modulation monitor at the transmitter site produces a positive excursion of the audio wave modulation of a carrier wave proportional to percentage modulation of a carrier wave. A special rectifier circuit having the "semi-peak" response characteristics specified by the FCC for the indicating meter of the modulation monitor is used to measure the excursions of the audio wave. The DC output of the rectifier circuit is sampled periodically and converted to parallel digital data by a standard analog to digital converter. This data is converted into a serial data stream by a parallel to serial converter for transmission through a conductor to the remote site. The serial data received at the remote site is reconverted to parallel data which is fed to a down counter.
