Abstract: An integrated apparatus and method is provided for a collar that is configured to operate as part of a wireless fence system that contains and monitors the location of a dog within containment area defined by the wireless fence system and further configured to provide GPS tracking capability when the dog has escaped from the containment area. As long as the dog remains in the area defined by the wireless fence, the collar operates solely in a wireless fence mode, communicating with the transmitters used as part of the wireless fence system. The GPS tracking function remains “asleep” and is not activated unless and until the dog escapes. Once GPS mode is activated, fence mode is shut down and operation of the GPS enables the dog owner or other individual to receive SMS messages and/or email with information on the dog's location on a smart-phone, tablet or PC.

Abstract: A motion activated water repellant sprinkler device for repelling animals that can be remotely controlled is provided. When the device is in on mode, the user can remotely adjust the sensitivity setting of the motion detector, set a time period for which the sprinkler will continually spray, and turn off the device so that the user can approach the device without being sprayed. The ability to set a particular time period for continuous sprinkler activity allows the motion activated water repellant sprinkler device to be used not only as an animal deterring device but also as a watering device for grass and other plants.

Abstract: Polarization preserving projection screens provide optimum polarization preservation for 3D viewing. The projection screens additionally provide improved light control for enhanced brightness, uniformity, and contrast for both 2D and 3D systems. Generally, the disclosed method for providing a projection screen comprises stripping an optically functional material from a carrier substrate, thus creating engineered particles from the optically functional material. The engineered particles may then be deposited on a second substrate to create a substantially homogeneous optical appearance of the projection screen.

Abstract: A remote notification electronic rodent trapping system and method is provided having a plurality of electronic rodent trapping devices configured to wirelessly communicate trap information to each other and to a PC or wireless device. According to one embodiment, each trap is equipped with an RF transceiver and the rodent trapping devices form a mesh network with one another in which the trapping devices act as repeaters so that if one trap loses connectivity with the PC, information from that trap can be transmitted to the PC via another trap. According to an alternative embodiment, the traps individually report directly to the base station or to the base station via one or more repeaters, the repeaters enabling the range of the direct individual reporting configuration to be greatly increased.

The web server hosting the website can also provide trap status data directly to a smartphone app on a user's smartphone. In addition, the website can send email and text notification to any remote device capable of receiving email or text messages.

Abstract: A vibrating oral care device for cleaning interdental spaces includes a housing which can be gripped by human fingers. A battery is located within the housing. An electric vibrator is also located within the housing. A switch on the housing is used to electrically connect the battery to the vibrator. A rigid element extends from one end of the housing. When the switch is operated to connect the battery to the vibrator, the vibrator vibrates and causes the rigid element to vibrate.

Abstract: An electronic animal trap with a CPU-controlled, rearming, three-killing-plate configuration and extended killing cycle for trapping and exterminating larger rodents such as rats. The high-voltage output circuit is connected to a pair of killing plates which are activated with a high-voltage pulse train for a killing cycle when a pest of known impedance is sensed across said pair of plates. A third killing plate, electrically coupled to a first plate of said pair of plates, is brought to the voltage level of the first plate within approximately 1 msec of circuit activation for increased kill and escape-prevention capabilities.

Abstract: A flexible optical marker is applied to an optical scale substrate to make an optical scale assembly for an optical position encoder. The marker may be a limit marker, index marker, or other type of marker. The marker substrate may be a plastic film such as polyester, singulated from a “recombine” roll created by a web process. The marker has a microstructured pattern on one surface that is covered with a reflective metal coating. The marker also has an adhesive layer and is affixed to the optical scale substrate by a process of aligning the marker to an edge of the scale and then applying pressure to the upper surface of the marker. The marker may be applied with a handle portion that is separated from the marker after the marker is affixed. The marker may be especially useful with a flexible scale substrate such as a metal tape substrate.
