Filed:

Jan 21, 2005

Appl. No.:

11/040960

Inventors:

Samuel L Landsberger - Rancho Palos Verdes CA, US

International Classification:

A61F 2/66

US Classification:

623 57, 623 64, 294 991

Abstract:

An artificial hand includes a finger group which is pivotally connected to a thumb. The finger group and thumb are resiliently biased toward one another. The finger group and thumb have hooked articulated distal ends. When the artificial hand and the object are brought together, the finger-group and the thumb part to allow the object to pass into a capture zone. The articulated distal ends bend inwardly to assist in the passage of the object. Once in the capture zone the finger group and thumb close about the object thereby holding it is place. The hooked distal ends also serve to retain the object within the capture zone. In another aspect of the invention the finger group includes two finger subgroups which are also resiliently biased together to hold objects.

International Classification:

A61F 5/00

US Classification:

602 23, 602 27

Abstract:

An ankle-foot orthosis for aiding or enhancing a user's foot and ankle movement, wherein the orthosis comprises at least one strut member, a calf shell, a foot shell, and a plurality of segments. Gaps formed between adjacent segments, an uppermost segment and the calf shell, and a lowermost segment and the foot shell have gap widths, wherein gaps at a higher location have larger gap widths than those at a lower location. Therefore, in dorsiflexion, the gaps close in series from bottom to top, gradually increasing the orthosis stiffness, creating a progressive dorsiflexion stop, and decreasing the magnitude of loads transferred into the user. In plantar flexion, the gaps similarly decrease in series from bottom to top, gradually increasing the orthosis stiffness, creating a progressive plantar flexion stop, and decreasing the magnitude of loads transferred into the user.

US Classification:

602023000, 602026000

Abstract:

A knee orthosis comprising of at least one deflection limiter () separated by gaps () on one or more struts (), which are attached to a thigh shell () and a calf shell (). The stiffness of the brace can easily be controlled in sagittal, transverse, and coronal planes whereby a person may obtain improved gait.

Kalpa Engineering, Inc. - Redondo Beach CA

International Classification:

A61B 1756

US Classification:

606 60

Abstract:

Devices for lengthening bone, particularly the mandible and other small bones, by distraction osteogenesis are presented. The devices are implantable in an appropriate surgical procedure, and provide for an optional flexible drive shaft, used to transmit controlled torque for elongation of the devices thereby effecting distraction osteogenesis, which optional flexible drive shaft may conveniently terminate within the oral or buccal cavity. In one embodiment, the devices provide a telescoping screw assembly and drive means, which drive means may be an angled gear drive. In another embodiment, a threaded flexible drive shaft is provided which provides for elongation of the devices thereby effecting distraction osteogenesis.

US Classification:

405191

Abstract:

An underwater robot is employed to clean and/or inspect the inner surfaces of high flow rate water inlet pipes for various facilities, such as power plants, water treatment plants, etc. The robot crawls along a cable positioned within a pipe to be inspected or cleaned, and in one embodiment, includes a plurality of guidance fins which rely upon the flow of water through the pipe to position the robot therein as desired. Retractable legs can also be provided to fix the robot at a location within the pipe when it is employed to clean the pipe using a water jet or similar system. The robot can also include a water driven turbine for generating electricity for the various motors, servos and other actuators contained on board the robot. Also, the robot preferably includes wheel or pulley arrangements which further help the robot to negotiate sharp corners or other obstructions within the pipe to be inspected or cleaned.

International Classification:

US Classification:

405127

Abstract:

A method and apparatus for eliminating zebra mussel colonizations from fresh water intake pipes for facilities, such as power plants and water treatment plants, are disclosed. One or more small diameter alternate intake pipes are disposed within a main intake pipe, and the pipes are connected by means of individually controllable valves to a pump for supplying water to the facility. Zebra mussel build up along the interior walls of any of the pipes is eliminated by shutting off flow in any mussel infested pipes with the valves, which causes starvation of the mussels due to suffocation. When water flow is resumed, the dead mussels are easily washed out of the pipes. The alternate intake pipes can be made of inexpensive flexible material, such as rubber, since they are not exposed to the environment external to the main intake pipe. In addition, a non-stick coating, such as silicone, can be disposed on the interior walls of the alternate pipes to further prevent mussel build up. A number of techniques for installing the one or more alternate pipes within an existing pipe are also disclosed.
