Abstract: A vented combustion chamber for an insect attractant engine is provided for a flying insect trapping device of the type that relies upon combustion of a fuel to generate a flow of carbon dioxide to attract flying insects. The combustion chamber, which is generally tubular and horizontally oriented in operation, is vented through a hole formed in one side of the chamber wall that extends from the outer surface of the chamber into the interior thereof. During operation of the device, this through-hole allows gas inside the chamber to be vented to the outside, changing the effective length of the combustion chamber for the purposes of wave generation is changed so that creation of a resonance cycle or standing wave, and the resulting acoustic phenomenon of howling, is prevented.

Abstract: A remotely activated door-opening mechanism is provided for a cage trap having an animal enclosure, preferably a cage trap as disclosed in U.S. Publ. No. US2008/0115405. The mechanism is mounted outside the enclosure of the trap and is preferably remotely activated by an IR or RF transmitter to open a door of the trap and release a trapped animal when the operator is at a safe distance away. The mechanism may also be manually set with a time delay and may be associated with either a main entry door to the trap or with a secondary escape door located at an opposite end of the trap.

Abstract: A custom-shaped wireless fence system is provided that contains one or more dogs in a user-defined containment area without the need for a physical fence or underground wire. The system, which is easy to set up and use, includes at least three base units and at least one collar and, preferably, a remote controller. A virtual fence is defined around the containment area, as well as around optional exclusion zones within the containment area, during system set up through communication between the base units and a trackable device as the user walks around the desired border. Visualization software enables the user to verify that the location of the fence is as desired and that the system is operating properly using a computing device having a display screen. In use, the system employs improved filtering of consecutive distance measurement values taken between the base units and the collar to discount errant measurement values in terms of their contribution to the current calculation of the dog's location.

Abstract: A single use, hermetically sealing mousetrap has a housing defining an enclosure that contains a killing mechanism which is accessible through a rotatably mounted door controlled by a spring-loaded door opening gear mechanism. Mounted to the bottom of the housing inside the enclosure is a spring-actuated setting axle and setting bar combination that is movable between a tripped position and a set position by manipulation of a setting handle positioned outside the enclosure. When the setting axle is moved to the set position, the door opening gear mechanism causes the door to open while tensioning a torsional door spring. A trip latch and bait pedal are configured to operate together to secure the setting bar in the set position, with subsequent movement of the bait pedal by a mouse serving to release the trip latch. When the trap is thereby triggered, the setting bar moves to the tripped position where it both activates the killing mechanism and releases the door opening gear mechanism.
