Abstract: A system 100 for tracking the movement of multiple objects within a predefined area using a continuation of overhead X-Y tracking cameras 24 with attached frequency selective filter 24f. Also employed are perspective Z filming cameras sets 30. Objects to be tracked, such as player 17, have been marked to include some form of frequency selective reflective material such as an ink. Typical markers include patches 7r and 7l, sticker 9 and tape 4a as well as additional body joint markers 17af through 17l. System 100 radiates selected energy 23a throughout the predefined area of tracking that is specifically chosen to reflect off said reflective materials used to mark for instance player 17. The reflected energy is then received by tracking cameras 24 while all other ambient light is blocked by filter 24f. Local Computer System 60 continuously captures images from said tracking cameras 24 which include only the minimum information created by said reflected energy.

Abstract: A system 100 for tracking the movement of multiple objects within a predefined area using a combination of overhead X-Y filming cameras 25 and tracking cameras 24 with attached frequency selective filter 24f. Also employed are perspective Z filming cameras 25 and tracking 24 cameras with filter 24f. Objects to be tracked have been marked to include some form of frequency selective reflective material, such as an ink. Marked objects such as patches 7r and 7l, sticker 9 and tape 4a have been specified and are attachable to said multiple objects. System 100 radiates selected energy 23a throughout the predefined area of tracking that is specifically chosen to reflect off said reflective materials used to mark said objects. Reflected energy such as 7m, 9a and 4b is then received by tracking cameras 24 while all other ambient light is blocked by filter 24f. Local Computer System 60 continuously captures images from said tracking cameras 24 which include only the minimum information created by said reflected energy.

Abstract: A system 200 for tracking the movement of multiple objects within a predefined area using a combination of overhead X-Y filming cameras 125 and tracking cameras 124 with attached frequency selective filter 124f. Also employed is perspective Z filming cameras 125 and tracking cameras 124 with filter 124f The preferred energy source is existing rink lamp 10 that emits electromagnetic by-product radiation in either the UV range for typical Metal Halide lamps or the IR range for typical Xenon Arc lamps. Foreground objects to be tracked such as player 110, jersey 105, stick 104 and puck 103 have been marked to include some form of frequency selective reflective material, such reflective material 20a, retroreflective material 20b or fluorescent material 20c. Prior to marking, foreground objects such as jersey 105 and stick 104 have first been treated with either a UV or IR absorbent compound such as 24 that absorbs incident tracking energy rays.

Abstract: An automatic labeler system for demarcating objects is disclosed. The system includes a device, such as for dispersing an optically responsive material onto the surface of each object. The material changes color in response to focused energy. The focused energy is provided by a device for optically demarcating the material by controllably directing focused energy, such as a laser, onto the optically responsive material. The system also includes a scanning device for scanning the surfaces of the objects with energy to determine the topology of the surfaces. The automatic labeler system is particularly useful in labeling stacked materials, such as individual boards in bundled lumber.

Abstract: An automatic means for labeling includes means for scanning a group of objects to determine the coordinates of an object in the group of objects, means for storing data representative of the determined coordinates of the object and means responsive to the data storage means for spraying self adhering materials in separate geometric areas with varying reflective properties to create an identifying pattern on the object.

Abstract: A conventionally constructed baby walker 5 having a lower support member 6 to which are attached front wheels 10 and 11 (not shown) and rear wheels and 12 and 13 (not shown) in contact with floor surface 14 has further magnetically activated brake assembly 21 moveably attached to support member 6, the bottom surface of which is also in contact with floor surface 14. Brake assembly 21 further contains a permanent magnet disposed above surface 14 and attached to an internal latching mechanism. A magnetically permeable arc shaped strip 15 is further attached to floor surface 14 using conventional screws 19. Preferably strip 15 is placed in front of staircase 20 or other level drop such as may be encountered with a patio or porch. As walker 5 is propelled across surface 14 and over strip 15, the permanent magnet is downwardly attracted to the permeable strip releasing the latching mechanism and engaging brake assembly 21.

Abstract: A conventionally constructed baby walker 5 having a lower support member 6 to which are attached front wheels 10 and rear wheels 12 in contact with floor surface 14 has further optically activated brake assemblies 21a and 21b both moveably attached to support member 6, the bottom surface of each is rollably in contact with floor surface 14. Brake assemblies 21a and 21b each contain an infrared emitter and photodiode disposed above surface 14 and connected to a control circuit. An optically encoded arc shaped strip 15 having a pattern of alternating reflective and non reflective bands is further attached to floor surface 14 using conventional screws 19. Preferably strip 15 is placed in front of a descending staircase 20 or other level drop such as may be encountered with a patio or porch. As walker 5 is propelled across surface 14 and over strip 15, the optically encoded pattern is detected by the infrared emitter--photodiode combination of braking assembly 21a.

Abstract: On Fork Lift 100, Load Cell Assemblies 40a and 40b are affixed to Fork Arms 32a and 32b and as such are capable of determining the weight of any object lifted by Fork Arm Lift Assembly 30. Continuous weight information is transmitted from Assemblies 40a and 40b to Fork Lift Computer 52 via wires and IR Transmitter 44 and Receiver 48. Changes in weight information are interpreted as load engagement and disengagement by Computer 52, which then responds by receiving the current relative vertical height of Fork Arm Lift Assembly 30 from Ultrasonic Distance Measuring Unit 56. The Computer 52 then transmits, via Telescoping Antenna 70, an uniquely encoded signal with both weight and height information to Stationary Elevated Locating Modules such as 74a and 74b, which have been strategically placed throughout the operating range of Fork Lift 100. This signal is then transmitted to Unit Tracking Computer System 80 by Locating Modules such as 74a and 74b.

Abstract: The invention provides an inexpensive and electrically isolated remote monitoring apparatus for monitoring the operational status of any oxygen concentrator by specifically monitoring the standard set of high and low pressure diagnostic light emitting diodes provided with most concentrators. Flexible boots enclose the respective optodetectors and are forceably pushed over the diagnostic diodes of the oxygen concentrator so that any light emitted by either diode is detected by the respective optodetector. The optodetectors are further connected to a microcontroller. A telephone line interface port connects to the microcontroller and provides for a telephonic communication link between the microcontroller and a remote computer. When a malfunction is detected and analyzed by the microcontroller, both the type of malfunction and a location code is transmitted to the remote computer.

Abstract: Either a focused beam (22) or a spatial (42) movable scanning unit which is attached to a moveable horizontal arm (27) which is attached to a stand (26) such that the scanning unit can be controllably directed throughout a prescribed vertical-horizontal plane which is parallel to one end of a unit of lumber (10). Separate stands (26) are placed at either end of the unit (10). Throughout the automatic directed movement, the scanning unit either emits focused beam (38) and/or receives reflected energy beams (38 and 48) which have reflected off the end of unit (10). These reflected beams are in accordance with the surface pattern of unit (10) and are input to a topological processor (22b or 42b) which translates this information into the geometric attributes of thickness, width and length. The exact count of distinct pieces of lumber of distinct geometric attributes is then transmitted to computer (28) as the unit's end tally.
