Title: Computer controlled hydraulic resistance device for a prosthesis and other apparatus
Inventor: PETROFSKY STEVEN H
IPC: A61F2/70
Filed: 1998-03-18
Abstract: A computer controlled hydraulic resistance device for apparatus such as a prosthetic knee for above knee amputees, includes a solenoid actuated valve connected to control the flow of hydraulic fluid to and from a hydraulic actuator which applies resistance to the prosthetic knee or other apparatus through a coupling.   Hydraulic pressure is sensed on the high and low side of the actuator and is used by a micro-controller  in a closed-loop manner to compensate automatically for variations in the device and in the hydraulic fluid viscosity.  The device also senses the position of the apparatus and feedsback to the micro-controller for applying a predetermined resistance profile to the apparatus.

Title: Camera/lens calibration apparatus and method
Inventor: MATHISEN ALLEN E
IPC: G06T13/00
Filed: 1998-03-31
Abstract: A method and apparatus for generating a viewport definition for a computer generated image using sensor information relating to a video camera's pan, tilt, zoom, and focus controls. The method generally comprises the steps of: (a) establishing reference points within an enclosed space which is to be used for recording images with the camera: (b) positioning the camera within the enclosed space relative to the reference points such that the camera position can be determined through triangulation with respect to the reference points: (c) developing position data through triangulation which identifies the camera position in a coordinate system relative to the reference points; (d) recording camera orientation data from sensors disposed to detect camera parameters defining the camera's pan, tilt, zoom, and focus settings; and (e) developing a database defining a viewport for the camera defined from a combination of the position data and the camera orientation data. Calculating the viewport (i.e., a nodal point or eyepoint, an orientation, a field of view, a focal plane distance, and a focus of expansion) as the camera moves is the ultimate goal of the camera tracking device.

Title: Information adding/extracting method, information adding/extracting system, information signal processor and information signal recording medium
Inventor: OGINO AKIRA
IPC: G10L25/00
Filed: 1998-05-19
Abstract: A summing section adds, by summing process, additional information corresponding to the least significant bit of the digital video signal S1 to the digital video signal S1 and records the video signal S2 to which the additional information is added to a recording medium with a writing section.  When the video signal, being recorded on a recording medium, to which the additional information is added is duplicated to the other recording medium, the additional information is extracted for utilization by subtracting the original video signal to which the additional information is not added from the duplicated video signal to which the additional information is added.
Patent CA-2242183-A1 (CA)
Inventor: SANTORO RALPH JR
IPC: B60T13/66
Filed: 1998-07-03
Abstract: A brake pipe control apparatus of the type that defines primary and control passage networks has been improved. The primary passage network interconnects the brake pipe to at least one pneumatic valve in the apparatus. The control passage network interconnects a source of control pressure to at least one magnet valve used to cause operation of the pneumatic valve(s). The improvement includes first and second check valves and a passageway added between the two passage networks. The first check valve is incorporated into the control passage network between an inlet channel thereof that connects to the source and a branched channel thereof that connects to the magnet valve(s). The first check valve is situated to prevent air from flowing to the source from the branched channel when pressure in the source is low relative to pressure in the branched channel. The passageway interconnects the branched channel and the primary passage network. Placed into the passageway, the second check valve is situated to allow air to flow from the primary passage network to the branched channel when pressure in the source is low relative to pressure in the brake pipe. Pressure is thus maintained in the branched channel thereby allowing the magnet valve(s) during operation thereof to cause proper operation of the pneumatic valve(s) of the apparatus even if the source fails to provide air at the control pressure ordinarily expected.

IPC: F16B15/00
Filed: 1998-11-18
Abstract: As formed from a predetermined length of carbon steel wire, such as AISI C 1062 steel wire or high-manganese carbon steel wire, in sequential forming, rolling, and austempering steps, a pin for axial, non-rotational penetration into a steel, concrete, or masonry substrate has a head, a tapered shank, a point having a tip, and a transition zone between the tapered shank and the head. The head has an outer diameter at least about 2.6 times greater than the initial diameter of the wire predetermined length. The smaller end of the tapered shank has a diameter about 0.6 times the initial diameter thereof. The larger end of the tapered shank has a diameter about 0.7 times the initial diameter thereof. The point is joinedunitarily to the smaller end of the tapered shank and conforms except at the tip, which is rounded, substantially to a tangent ogive, which is tangent to the tapered shank. The transition zone has a tapered portion with a smaller end joined unitarily to the larger end of the tapered shank and a with larger end joined unitarily to the head at a circumferential fillet. The larger end of the taperedportion of the transition zone has a diameter about 1.1 times greater than the initial diameter of the wire predetermined length. The axial length of the transition zone is less than about one half of the axial length of the tapered shank. The austempering step provides the pin with a surface hardness not greater than about Rockwell C 48 and with a core hardness in a range from about Rockwell C 48 to about Rockwell C 58.
