DETAILED DESCRIPTION OF THE EMBODIMENT(S)

[0032] The invention is explained in greater detail below with reference to embodiments of a laser soldering system. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and still fully convey the scope of the invention to those skilled in the art. It is to be understood that the embodiments described herein are disclosed by way of illustration only. It is not intended that the invention be limited in its scope to the details of construction and arrangement of components set forth in the following description or illustrated in the drawings. Also, in describing the preferred embodiments, specific terminology will be resorted to for the sake of clarity. It is to be understood that each specific term includes all technical equivalents which operate in a similar manner to accomplish a similar purpose.

[0033] As shown in FIG. 1, the present invention is directed to a live catch trap generally designated by reference numeral 10 having a trap body 12 with a lid 13 and at least one entrance 11 through which a rodent enters the trap body 12. A light-based sensor 115 is mounted on an inner surface of the trap above the floor 36 of the trap. The floor 36 of the trap 10 preferably includes a glue board 14 (see FIG. 2).

[0034] According to a first embodiment shown in FIG. 2, the trap 50 includes a microprocessor 16 in communication with a visual image device such as a CMOS or CCD camera 18. The camera 18 evaluates the status of the trap interior, either periodically or in response to an event indicating rodent or insect activity as detected by a detector 20 and provides data to the microprocessor 16. The detector 20 may be a motion detector/accelerometer or a pressure and/or temperature sensor. The microprocessor 16 evaluates the data received from the camera 18 and determines the type of activity that has been detected which is then transmitted via a communication transmitter 34 to the smartphone, PC or like device of a remote user 32, preferably via the cloud 30. The user may thus be apprised of the trap condition and status without having to physically access the trap for hands-on evaluation.

[0035] A second embodiment of a live catch trap 100 according to the present invention is shown in FIG. 3. As in the first embodiment, the trap 100 includes a trap body 12 that preferably includes a glue board 14 although, as in the first embodiment, inclusion of a glue board is not necessary. However, instead of a camera, the trap 100 includes a light detecting sensor embodied as a reflectivity sensor 118 comprised of a light transmitter 22 and a receiver 24 in communication with the microprocessor 16. The microprocessor 16 uses data from the reflectivity sensor 118 to evaluate the amount of light transmitted by the transmitter 22 that is reflected off an inner surface of the trap, such as the floor surface 36, and received by the receiver 24, as depicted in FIG. 4A, to determine the presence and extent of foreign bodies including debris, insects and/or rodents on the floor 36 of the trap. While the reflectivity sensor 118 is shown as being mounted on the upper surface of the trap, the sensor could alternatively be mounted on a side surface of the trap with another side surface and/or the floor of the trap serving as the reflective surface(s) to be evaluated. The reflectivity sensor may be any sensor for detecting light including visual light, IR light, UV light, and the like, alone or in combination. Whatever wavelength of light is being detected, the associated light or reflectivity sensor may be operated periodically, such as at set or variable intervals, or continuously to monitor trap status. In addition, the light or reflectivity sensor may be used in conjunction with an activity sensor like detector 20. When combined with an activity sensor, the trap may be configured to activate the light or reflectivity sensor in response to an activity sensor or detector input indicating the presence of a rodent or the occurrence of other activity of potential interest within or adjacent the trap.

[0036] If a glue board 14 is included, it may be positioned on the floor 36 as shown in FIG. 4B and serve as the surface being evaluated by the reflectivity sensor. As would be understood by persons of skill in the art, if a glue board is the surface being evaluated, the baseline used for the light that is reflected back would be different as compared to the light reflection baseline of the trap floor itself, i.e., the trap floor without a glue board. In either case, the condition of the trap in terms of cleanliness and/or pest presence is reported to the microprocessor 16 which evaluates the data and, using the communications transmitter 34, transmits the type of activity detected to the user 32, preferably via the cloud 30. The user may thus be apprised of the trap condition and status without having to physically access the trap for hands-on evaluation.

[0037] A third embodiment of a live catch trap 150, also using a light detecting sensor according to the present invention, is shown in FIGS. 5, 5A and 5B. As in the first and second embodiments, the trap 150 includes a trap body 12 that preferably includes a glue board 14 although, as in the previous embodiments, inclusion of a glue board is not necessary.

[0038] The light detecting sensor used to monitor rodent activity or presence in the trap 150 is a photo sensor 218 that includes an LED array 152 and a photodiode array 154 in communication with the microprocessor 16. As shown in FIG. 5A, the photo sensor 218 preferably includes at least one amplifier 156 and at least one high pass filter 158. If a glue board 14 is included, it may be advantageously positioned between the LED array 152 and the photodiode array 154 to substantially correspond with the likely position of a rodent 15 as shown in FIG. 5B.

[0039] The light emitting diodes of the LED array 152 are configured to generate an output periodically and/or in response to an activity sensor. Preferably, the LEDs are pulsed with a waveform that has frequency components above 1 kilohertz, which is above frequencies commonly found in light sources such as LED or fluorescent fixtures. The light output 153 of the LED array stimulates the photodiode array 154 when no rodent 15 is present to block the light emitted by the LED array 152. Outputs from the photodiode array 154 are passed through the amplifier(s) 156 and conditioned via the high pass filter(s) 158 for ambient light elimination before being passed to the microprocessor 16. The high pass filter 158 preferably has a corner frequency of approximately 400 Hertz and a gain of 25×. A representative schematic of a photodiode amplifier and high pass filter circuit is shown in FIG. 6. A representative schematic of an LED array is shown in FIG. 7.

[0040] As rodents have a predictable profile, the microprocessor 16 is programmed with pattern recognition capability which is applied to the output of the high pass filter 158. When a rodent 15 is not present, the light from the LED array 152 stimulates the photodiode array 154 on the other side of the trap body 12 along most or all of its extent. Blockage of the light, as evaluated with pattern recognition software such as by using an internal processing algorithm or the like, however, is interpreted by the microprocessor 16 as indicating the presence of a rodent which may then be reported to the user 32, preferably via the cloud 30. Hence, as with the first two embodiments, the user may be apprised of trap condition and status without having to physically access the trap for hands-on evaluation.

[0041] To reduce the risk of false indications of rodent presence, the photodiode and LED arrays are preferably spaced vertically above the floor of the trap at a sufficient height to prevent the light beams from being interrupted by low-lying contamination such as insects or dust in the trap body. The number of LEDs and photodiodes in each array may be varied as would be understood by persons of skill in the art.

[0042] The present invention is further directed to a method of monitoring rodent and/or insect activity in live catch traps, and/or trap cleanliness, and for transmitting trap status information to a remote user via cloud computing as summarized in the flowchart of FIG. 8. According to the method, a trap having a light-based or visual sensor and transmission capabilities is placed in a trap location, step 200. If the trap is equipped with an activity sensor, step 202, upon detection of activity, step 204, the visual sensor is activated to monitor the trap interior, step 206. The trap activity and trap interior status data is provided to the microprocessor, step 208, which evaluates the type of activity, step 210. The trap status and activity data is then transmitted to a remote user, step 212.

[0043] If the trap does not have an activity sensor, step 202, or if the trap does have an activity sensor, step 202, but no activity is detected for a predetermined length of time, step 204, the visual sensor may be activated periodically, for example several times each hour, at least once a day, or at any determined interval, to monitor the status of the trap interior, step 220. The trap interior status data is provided to the microprocessor, step 222, which evaluates the status data, step 224. The status data is then transmitted to the remote user, step 212.

[0044] In the case of a visual image device such as a CMOS or CCD camera, evaluation of the status data, step 224, includes the microprocessor evaluating a picture taken by the camera to determine the type of trap activity shown in the picture, including whether a rodent is present, which may then be reported to the remote user.

[0045] In the case of a light reflectivity sensor, evaluation of the status data, step 224, includes the microprocessor evaluating the amount of light received by the receiver, after being transmitted by the light transmitter and reflected off an inner surface of the trap, to determine the presence of foreign bodies and/or a rodent in the trap for reporting to the remote user.

[0046] In the case of a photo sensor, evaluation of the status data, step 224, includes the microprocessor determining that a light pattern in the output received from the photodiode array indicates that at least part of the light emitted by the LED array was not received by the photodiode array. The microprocessor then uses pattern recognition to determine whether the light pattern of the photodiodes corresponds with a predicted pattern for a rodent.

[0047] With the live catch traps and method as described herein, unnecessary checking of traps that have not undergone any activity is avoided. When rodent activity has occurred, however, the trap both detects and evaluates the activity to provide the remote user with a report on the nature of the activity as well as the functional status of the trap in terms of its content which may include cleanliness. In addition, the ability to perform trap status checks at predetermined time intervals regardless of the presence or absence of activity, typically at least once a day but with variable time interval checking capability, and to transmit this information to a remote user, helps to ensure that the trap's functional readiness is efficiently maintained. The trap may also be configured to enable the remote user to request trap status information independently of trap activity.

[0048] The foregoing descriptions and drawings should be considered as illustrative only of the principles of the invention. The invention may be configured in a variety of shapes and sizes and numerous applications of the present invention will readily occur to those skilled in the art. Therefore, it is not desired to limit the invention to the specific examples disclosed or the exact construction and operation shown and described. Rather, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
