Abstract: A measuring device capable of being used by physicians, veterinarians, and surgeons either pre-operatively, intraoperatively, or post-operatively to determine the actual size of objects shown in images made by x-rays (and other imaging techniques). The measuring device is electronic and can also be used to measure the angle between two objects whose images are shown. The measuring device can also be used to determine the proper size and shape of implants to be surgically implanted in a living body. The device can also be used to determine the proper size and shape for templates to be used to select an implant to be surgically implanted in a living body.

Abstract: A sprinkler valve suitable for flows from about one (1) to two (2) gallons per hour to thirty (30) to forty (40) gallons per minute. A double diaphragm utilizes a principle of differential areas to create force for any non-zero pressure through the valve. This feature, in conjunction with momentary fluid flow in the solenoid circuit, is responsible for complete regulation of the flow characteristics of the valve. The requirement for large shut-off springs and flow control adjustment screws has been eliminated. The flow may be determined by the size of the valve. The need for solenoid springs has been eliminated. In one embodiment two (2) separate diaphragms utilize a principle of differential areas to create force for any non-zero pressure through the valve. This feature, in conjunction with momentary fluid flow in the solenoid circuit, is responsible for complete control of the flow characteristics of the valve.

Abstract: A telescoping stand combining mechanical memory with integrated internal electrical wiring with plug-in connectors. The stand is equally suitable for mounting various electro-mechanical devices including, but not limited to, musical drums (electric or acoustic), lighting fixtures, displays, consoles, keyboards, and other items or devices where repetitious precise mechanical positioning with integral internal electrical connections is required. Once initially set up, the stand can be locked for height and rotation (vertical and horizontal, or radial, angular, and polar) and is then ready for disassembly and subsequent re-assembly and connection to external electrical circuits after which re-assembly the precise mechanical positioning of the mounted devices will be restored.
