DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] FIG. 1 shows the elements of an embodiment of cable mounted transport mechanism 100. The main components of this embodiment of transport mechanism 100 include, for example, main housing 102, sensor housing 104, food storage container 106, dispenser assembly 108, gear assembly 110, locomotion motor 112, transmitter/receiver 114, power source 116, cable grip rollers 118, camera system 120, and processing 122.

[0016] FIG. 2 shows the elements of an embodiment of food storage container 200, along with dispenser 202. These particular embodiments of food storage container 200 and dispenser 202 are similar to but shown in more detail than food storage container 106 and dispenser assembly 108, respectively, of FIG. 1. The main components of the embodiments of food storage container 200 and dispenser 202 include, for example, bracket 204 (which connects food storage container 200 to the applicable structure of the driving portion of the transport mechanism), spreader motor assembly 206, shaft 208 (the lower portion of which is connected to dispenser 202), spreader wheel 210, feed supply regulator paddle 212, feed supply regulator motor 214, feed supply cutoff 216, and feed supply cutoff motor 218.

[0017] FIG. 3 shows a schematic of various sensors that can be used in a preferred embodiment of the present invention. The sensors are chosen to, for example, monitor (a) the health of the system, (b) the reaction and status of the spreading activity, and (c) the status of material spread. The sensors of FIG. 3 would be situated, in one embodiment of the present invention, in and in proximity to the equivalent to sensor housing in FIG. 1. In the schematic, each of the sensors are connected to the equivalent of power source 116 in FIG. 1. Additionally, each of the sensors is directly connected electronically to CPU 300. Sensor 302 assists in the movement of the transport mechanism, thus the readings from sensor 302 are transmitted to CPU 300. Sensor 304 monitors the dispensing of food by the dispenser by reading the amount of food in the equivalent of food storage container 106, thus the readings from sensor 304 are transmitted to CPU 300. Sensor 306 monitors environmental considerations to be considered in the movement of the transport mechanism and/or the dispensing of the food. Accordingly, the readings from sensor 302, sensor 304 and sensor 306 are considered together in the activation and controlling of, among other components, the equivalents of dispenser 108 and motor 112 to control the positioning of system 298 and the distribution of food.

[0018] FIG. 4 shows an example of network of cables positioned over a series of ponds containing fish. One embodiment of the inventive system transport mechanism 400 is configured to ride along cables with segments 402-408 suspended over and along the sides of ponds 410-416. In another embodiment of the inventive system, transport mechanism 400 is anchored and attached to a movable length of cable upon which the dispensing mechanism 436 is attached, allowing the dispensing mechanism and associated sensors to move along the series of ponds. The 360-degree dispensing spread areas are shown as 418-432. Structure 434 is the housing and food filling station. When the dispensing is completed in a specific dispensing position (like dispensing spread area 418), transport mechanism 400 can move the dispensing mechanism 436 to the next dispensing position (like dispensing spread are 420) and repeats the dispensing process. When the storage container attached to transport mechanism 400 is out of food or the dispensing session is completed, transport mechanism 400 returns to structure 434 for system storage (when not deployed) and/or refilling, the latter of which removes the need to bring food distinctly to each dispensing position. When the present invention is used to feed, for example, pigs or chickens, it may be preferrable for the results of the dispensing to be spread food in a line, as opposed to spread over an area.

[0019] As shown in the flow chart in FIG. 5, a preferred embodiment of the inventive method includes the steps of (A) receiving, in a cable mounted transport mechanism, information regarding the timing for dispensing, (B) detecting and monitoring the amount of food in the food storage container attached to the transport mechanism, (C) accessing information about the position(s) from which food should be dispensed, (D) moving the cable mounted transport mechanism to the position(s) prescribed by the information accessed, and (E) dispensing food from the food storage container at the desired position(s) based upon the information regarding the timing for dispensing, the position(s) for dispensing and amount of food then in the food storage container,

[0020] The flow chart shown in FIG. 6 shows the general steps of the method expressed in FIG. 5 with additional steps and with a focus on the feeding of fish. The operator enters preferred dispensing times as part of receiving step (A). The current time is tracked against desired dispensing times and/or conditions (e.g., a specific time or dusk/dawn). When dispensing time has arrived, and if weather conditions are favorable, then the system executes a dispensing cycle. Otherwise, it can inform the operators that current conditions are not favorable for dispensing of food, medication, or other material.

[0021] In step (B), the system determines the amount of food, medicine or other material available in the storage mechanism to check against the amount required to perform the dispensing activity, as well as environmental conditions which could have an adverse effect on the material to be distributed. The required amount can be pre-determined by the operator or could be based upon historic dispensing data from prior dispensing. If there are insufficient material, the system can either alert personnel and request additional materials/supplies, or it may be able to automatically fill the storage mechanism itself (e.g., as part of a docking station). If the conditions are unsuitable for dispensing based upon the expected payload requirements, the system can inform the operators accordingly.

[0022] In step (C), the system is supplied information about the location to position the dispensing location, based upon the distance along the cable, a GPS position, a position relative to the geometry of, for example, the feeding pond/pen and surrounding area, or some combination of these.

[0023] In step (D), the system moves to the desired location to initiate dispensing.

[0024] In step (E), the system begins distributing the applicable material (e.g., feed or medicine) according to the information supplied by the operator about the activity. The material might be spread out radially or in a line and will be spread until such time as target conditions for stopping the operation are met. These conditions can be based upon, for example, the amount distributed, the area covered, the reaction of the animals being fed or some other metric determined by the operators.

[0025] The distribution of material can vary based upon the material being distributed and, for example, the animals and/or areas being serviced. In the case of highly competitive animals, such as fish, the food can be distributed radially all around the dispenser. Other animals which are less competitive, such as pigs, sheep, cattle, chickens, etc. can have food distributed in piles or lines.

[0026] The dispenser can be moved about the area using multiple methods of cable mechanisms. For example, the preferred dispenser and cable transport mechanism can be a combined unit that is attached to a cable of convenience and moves along the cable. In another embodiment of the system, the transport mechanism is anchored in one location and the cable is passed through the transport mechanism with the dispenser affixed to the cable. The transport mechanism thereby moves the dispenser by moving pulling the cable in one direction of another, much like a cable car is moved in one direction or another by a mechanism located in the base station. In yet another embodiment of the system, the dispenser can be attached to multiple cables at the same time, with transport mechanisms attached to each cable. The dispenser is then moved via coordinated activity of the transport mechanisms, much like the control of a camera suspended over a sports stadium.

[0027] Between missions and/or when weather or a system error requires, the mechanism returns the dispenser to a launch point or shelter point for servicing, storage, or reloading.

[0028] Because the transport mechanism can be centered over, for example, a pond to spread food, it can reach a larger number of eaters at one time. This breadth has a significant benefit over the conventional fling style dispenser, which sits on the shore or otherwise in a on the side fixed location spreading food in a narrow path, in that the transport mechanism, with the attached components, removes the geometric bias of food distribution from one side or one end of the dispensing area. Accordingly, the eaters (e.g., fish) are not forced to crowd together to compete for food. By spreading the food out more evenly, the eaters can access it more efficiently. This efficiency reduces food going unnoticed by the eaters due to them begin crowded together.

[0029] In a preferred embodiment, the sensing system tracks the activity of the eaters during dispensing. This monitoring can be accomplished by vision (e.g., watching the fish eaters), audio (e.g., listening to the activity of the fish while feeding), radar (e.g., monitoring the disturbance in the water due to fish feeding activities) or any other sensing mechanism that monitors the dispensing activity. When, for example, activity slows down due to the eaters becoming sated, the dispenser automatically stops distributing food. This type of curtailing prevents the waste of food, which otherwise might have gone uneaten and results in a significant cost savings due to feed being a sizable portion of an operation's expenses.
