Abstract: A hitch-mountable, collapsible stair assembly is disclosed for use in assisting mounting into a raised vehicle bed. The steps rotate between a generally vertical stowed position and a generally horizontal in-use position. The height of the steps above the ground is adjustable. The lower step can also be extended for ease of use.

Abstract: A communication channel between a first processor of a receiver and a second processor of a battery assembly is provided. The battery assembly requests a public key from the receiver. The receiver combines the public key with a private key stored in memory to form a first combined public key, applies a first hash function to the first combined public key, stores the resulting first hash value in memory and transmits the public key to the battery assembly. The battery assembly combines the public key with a corresponding private key to form a second combined public key, applies a corresponding hash function to the second combined public key and transmits the resulting second hash value to the receiver. The receiver compares the first hash value to the second hash value and enables operations of the receiver when the first hash value equals the second hash value.

Abstract: Described is a mechanically compliant stimulus delivery probe for delivering an electrical stimulus to an animal. The stimulus delivery probe is mechanically secured to an animal training device that is adapted to be carried by the animal and to generate the electrical stimulus. When the animal training device is carried by the animal, the stimulus delivery probe is positioned in physical contact with the animal such that the stimulus delivery probe delivers the electrical stimulus to the animal. The stimulus delivery probe is also mechanically compliant to the extent that the force applied by the animal training device against the stimulus delivery probe is substantially absorbed by the stimulus delivery probe, reducing the localized force realized by the animal. The reduction of the force realized by the animal promotes safety and comfort for the animal.

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 system is described that includes devices detecting and periodically transmitting data of events and conditions within an environment. The devices are communicatively coupled with applications running on processors of a remote server. The devices periodically request a connection with the applications, wherein the applications monitor a range of port numbers for receiving the devices' connection requests. The devices request connections at corresponding port numbers among the monitored range of port numbers. The applications accept the connection requests from the devices at the corresponding port numbers, wherein the devices transmit the data to the one or more applications during corresponding communication sessions. The applications evaluate attributes of the devices' connection requests and communication sessions and manage assignment of the devices to port numbers using information of the evaluating.

Abstract: A housebreaking reward system. The housebreaking reward system includes a moisture sensitive pad, a moisture detector, a reward dispenser, and an optional handheld transmitter. The moisture sensitive pad is constructed to contain and hold fluids (e.g., urine) deposited by an animal and is laid down at location where it is acceptable for an animal to eliminate. The moisture detector is selectively connectable to sensing elements on the moisture sensitive pad to detect when fluid is deposited. If fluid is detected, the moisture sensitive detector signals the reward dispenser to reward the animal for appropriate elimination. At least a portion the moisture sensitive pad is disposable to facilitate easy cleanup of the appropriate elimination area. After one or more fluid deposits, the moisture detector is disconnected from the sensing elements, and the used moisture sensitive pad is discarded.

Abstract: An animal containment system is described that comprises a transmitter unit and a receiver, the transmitter unit comprising a transmitter coil and signal generator. The signal generator transmits a modulated activation signal through the coil and generates a uniform magnetic field within a region around the coil. A receiver travels through a portion of the uniform magnetic field and uses information of periodically emphasized positively directed portions of the signal to detect a first polarity of the magnetic field in a first detection area and a second reversed polarity of the magnetic field in the second detection area. A detected reversal of polarity indicates a boundary crossing event including the receiver transitioning across the boundary.

Abstract: A laser pet toy including a light source with a focused beam of light of a predetermined shape and programmable random travel across an opaque surface such as a floor or wall to create an engaging image for a pet to play with the image for entertainment or exercise.

Abstract: A ball launching apparatus is provided. The apparatus includes a funnel residing at an upper end of a housing. The funnel includes a channel for gravitationally directing a ball into a launch point within an interior compartment of the housing. The apparatus includes a hammer that strikes a ball through a chute, thereby releasing the ball from the housing. Both the distance at which the ball travels and the angle at which the ball leaves the chute may be adjusted by the operator. A method of exercising a dog is also provided herein.

Abstract: Systems and methods of desensitizing an animal to an anxiety inducing event, including an output unit to communicate with a media player to output a conditioning media signal and an anxiety inducing media signal, a conditioning element dispenser to dispense a conditioning element, a detector to determine when an animal has taken the conditioning element, and a control module to selectively control operation of the output unit and the conditioning element dispenser to cause the conditioning element dispenser to dispense a first conditioning element in association with the media player outputting the conditioning media signal. The output unit can cause the media player to output the anxiety inducing media signal in association with the conditioning media signal, and the control unit can cause the conditioning element dispenser to dispense a second conditioning element from the conditioning element dispenser in association with the anxiety inducing media signal.
