Filed:

Nov 17, 2000

Appl. No.:

09/715432

Inventors:

David Levy - San Diego CA 92109

International Classification:

G09B 2328

US Classification:

434262, 434267, 434268

Abstract:

A medical simulation apparatus may include a housing, a vessel simulating tube carried by the housing, a liquid reservoir carried by the housing, a pump carried by the housing for circulating the liquid from the liquid reservoir through the vessel simulating tube, and an access port in fluid connection with the vessel simulating tube for receiving an instrument therein. The pump may be a pulsatile pump for providing a pulsed liquid circulation simulating blood flow. Also, the vessel simulating tube may include an elastic material (e. g. , silicone) expandable with the pulsed liquid circulation. Furthermore, the vessel simulating tube may include a portion having an enlarged diameter simulating an aneurysm, or it may include a portion having a restriction simulating a stenosis. Alternately, the vessel simulating tube may include a portion simulating an arteriovenous malformation or tumor.

US Classification:

700284, 13762411, 239 69, 307 66

Abstract:

The invention comprises devices and methods for providing operational power to a solar-powered irrigation control system. In one aspect, a method includes producing electrical energy from light, storing the electrical energy in a capacitive module, and operating an irrigation controller using the stored electrical energy independent of another power source. In another aspect, a device includes a control system comprising a computer having a programmed irrigation schedule which operates at least one irrigation device, a photovoltaic power module, and a capacitive module connected to said photovoltaic power module to store the electrical energy provided by the photovoltaic power module, where the capacitive module provides power for the control system to operate the at least one irrigation device independent of another power source.

Assignee:

Pet Product Innovations, LLC - Des Plaines IL

International Classification:

A01K 17/00
A01K 13/00
A45D 29/02

Abstract:

A claw shearing device including a pair of shearing elements having cutting edges that face one another, a fastener configured to pivotably attach the shearing elements, and an adjustable limiting mechanism connected to the pair of shearing elements. The cutting edges form an orifice for the insertion of a claw of an animal or a pet therebetween, where the maximum size of the orifice is limited by the adjustable limiting mechanism. The device is configured to bring together the shearing elements to cut the claw or nail of the animal or pet at a predetermined length.
