Abstract: The present invention relates to vibration analysis and in particular, but not limited to, the derivation of multiple types of vibration signals from one vibration signal for vibration analysis. In the preferred method of the invention the vibrations of an object are measured using at least one vibration sensor, wherein the vibration sensor converts vibrations into an electrical vibration signal. The electrical vibration signal is digitized based on a first frequency, wherein the first frequency is selected from a plurality of possible frequency values. A first type of vibration signal is derived from the digitized vibration signal. A second type of vibration signal is then derived from the digitized vibration signal based on a second frequency. The second frequency is rationally determined from, and lower than, the value selected for the first frequency. The invention also provides apparatus for deriving multiple types of vibration signals from one measured vibration signal for vibration analysis.

Abstract: Described is an electronic pet door for automatically granting a selected animal access to a through-way defined by the electronic pet door and denying a non-selected animal access to the through-way. The selected animal carries a transmitter. The electronic pet door includes a corresponding receiver and a frame that defines the through-way, which has a tapered contour. A flap, which has a tapered contour corresponding to the through-way, is disposed within the through-way and is capable of a locked position and an unlocked position. When in the locked position, the flap denies access to the through-way. When unlocked, the flap grants an animal access to the through-way. The flap is locked and unlocked by way of a locking mechanism that shifts the flap longitudinally between the less tapered and most tapered portions of the through-way. The locking mechanism shifts the flap in response to the receiver.

Abstract: A flexible locking dipstick module useful with a motor vehicle including an oil reservoir. A dipstick is disposed within a housing which has one end thereof affixed to the oil reservoir and extends therefrom to a location within the engine compartment of a motor vehicle. The end of the module disposed within the engine compartment includes a quick disconnect locking coupling providing for ready installation and removal of the dipstick. The coupling further provides protection against blow out of the dipstick in the event of inordinate build up of pressure within the oil reservoir. Further, one portion of the outboard coupling may be employed as a liquid-tight closure for a dipstick entry opening in the oil reservoir during removal and/or storage of the engine.

Abstract: A receiver for an animal training system which includes a stimulation unit for providing at least one stimulus having a quantity of energy pulses and a stimulus pulse width; and a controller connected to the stimulation unit. The controller receives at least one transmitted signal and assigns amplitude information and rate information to at least one correction signal. The stimulation unit receives the at least one correction signal and outputs a corresponding stimulus having the quantity of energy pulses corresponding to the rate information. The stimulus has the stimulus pulse width corresponding to the amplitude information.

Abstract: Described is an animal training device for delivering a response signal in response to receiving an audible signal. The animal training device is adapted to be carried by an animal and delivers the response signal, which includes a stimulus to the animal and an animal location indicator, in response to receiving the audible signal, which includes a voice command and other distinguishable sounds. The animal training device allows an animal handler to deliver a stimulus to the animal and generate a location indicator without using an additional device, such as a handheld transmitter.

Abstract: An apparatus and method of identifying an unknown word based on a known meaning, or word identification system. The word identification system allows a user that knows the meaning of a word but cannot recall the word that corresponds to the known meaning to identify the word through a series of simple questions. Each of the questions elicits information known about the unknown word through the knowledge of the meaning of the word and its use in language. With each response, the number of words matching the definitional characteristics is reduced until a set of one or more probable words and definitions for the unknown word is finally presented to the user.

Abstract: A concrete rebound shield and method of use is disclosed. The concrete rebound shield includes a bell defining an opening adapted to receive a feed hose. A collar nests within the opening of the bell and attaches to the feed hose such as to retain the bell onto the feed hose. The bell is adapted to substantially surround the feed hose and direct hydrated concrete toward a selected area.

Abstract: A patient transport apparatus. The patient transport apparatus of the present invention is articulated and sized to fit between the body and the open door of virtually all vehicles. Further, the patient transport apparatus uses a height-adjustable seat that is aligned with the vehicle seat to allow for simplified extraction of the patient from the vehicle. The height-adjustable seat lowers to just above ground height making the recovery of a fallen patient easier. A set of casters allows omni-directional travel of the patient transport apparatus for precise placement and a pair of primary motion wheels makes linear travel easier while providing a turning radius substantially approaching zero.

Abstract: A pet escape notification system for notifying a pet owner when a pet has escaped from a predefined boundary. The escape notification system is used in association with an electronic animal containment system for maintaining a pet within the predefined boundary. A pet unit transmitter is provided for delivering a proximity alert signal to a base unit when the pet unit receives a transmitting antenna signal. After receiving the proximity alert signal, the base unit begins sending a location inquiry signal to the pet unit. Upon receipt of the location inquiry signal, the pet unit broadcasts a location inquiry response signal. If the location inquiry response signal is received by the base unit receiver, the base unit processing unit determines that the pet is still within or close to the boundary. Otherwise the base unit controller activates a communication network to notify the pet owner that the pet has escaped.

Abstract: A housing forming a portion of an animal training device having a framing wall adapted to frame an LCD disposed internally of the housing.
