The invention provides progress over prior art shown for example in U.S. Pat. No. 5,912,700 by Honey 15 Jun. 1999, U.S. Pat. No. 4,998,441 by Stuart 12 Mar. 1991, U.S. Pat. No. 4,099,050 by Sauermann 04 Jul. 1978, and U.S. Pat. No. 4,053,233 by Bein 11 Oct. 1977.
The product is depicted schematically in the figure.
The data input product—which works with an information system 91—comprises a first coded data source, a first imager, and a computer-readable signal-bearing medium 11.
A first coded data source—41 for example—represents first data. A first imager which is signal connected with the information system has a first field of view extending along a first triad of orthogonal axes. The first field of view overlaps the first coded data source.
When the first imager is from a plurality of imagers 31, all signal connected 92 with the information system, the first field of view is in a collective field of view 33 of the plurality of imagers. The collective field of view can have parts which overlap other parts, can have parts which do not overlap other parts but meet other parts, and can have parts which do not overlap any other parts and do not meet any other parts. The collective field of view and parts of the collective field of view can change over time.
A first signal is caused by the first imager when the first imager detects first light from the first coded data source. The first light represents the first data. The first signal is input to the information system. The first signal represents the first light and thus represents the first data. When the first imager is from a plurality of imagers, the first light is part of collective light 32 detected by the plurality of imagers.
When the first coded data source is from a plurality of coded data sources, a second coded data source—51 for example—from the plurality of coded data sources source in the first field of view can specify second data. The first imager can detect first light from the first coded data source and second light from second coded data source concurrently and the first signal can represent the first light and the second light.
“Detect light” here and throughout means not only detecting the presence of light but also means detecting the specific properties of the light which represent first data so that the imager can cause a signal which represents the first data. Detecting light concurrently from several spatially separated coded data sources distinguishes the imager from a bar code reader which can not concurrently detect light from several spatially separated bar codes with the meaning of “detect” here.
The computer-readable signal-bearing medium is signal connected 93 with the information system. The medium has components which cause various actions by causing the information system to cause the actions. The medium has a use component 12 which causes at least part of the first data to be made available to a first application operated by the information system, when the first data specifies the first application.
When the imager detects the first light and can resolve the first light the first signal represents the first data. When the imager detects the first light but can not resolve the first light sufficiently for the first signal to represent the first data the medium can cause actions described below.
The medium can also have an output component 21 which is adapted to cause output of first output data calculated by the first application using the first data, when the use data specifies output. For example, the first data can represent a query and the first output data can represent an answer.
When the first coded data source is from a plurality of coded data sources, and the first application is from a plurality of applications operated by the information system, a second coded data source from the plurality of coded data sources can specify a second application from the plurality of coded data sources. The medium can cause at least part of the second data to be made available to the second application.
The medium can have a record component 13 which causes at least part of the first data to be recorded by the information system as part of use data available to the information system, when the first data allows recording. In a form of the product all coded data sources from a plurality of coded data sources can allow recording. In a form of the product only several coded data sources from the plurality of coded data sources can allow recording.
The medium can have an identity component 14 which causes an identity of the first coded data source to be recorded by the information system as part of the use data, when the first data allows recording of the identity. In one form of the product all coded data sources from a plurality of coded data sources can allow recording of the identity. In a form of the invention only several coded data sources from the plurality of coded data sources can allow recording of the identity.
The medium can have a region component 15 which is adapted to cause an imager from the plurality of imagers to image a region of space specified by the use data. In one form of the product any first coded data source from a plurality of coded data sources can specify a first region of space to be imaged. For example, there could be use data needed by an application in the first region. In this example the use data could be analog use data, digital use data, and combinations if these.
In a form of the product the medium can cause the imager to image a region of space which is not specified by any coded data source but is caused to be specified by the region component and the use data. For example, if the light from a coded data source detected by a first imager is not sufficient to represent the first data, then the medium can cause various actions such as zooming the first imager in on the region of space containing the coded data source, moving the first imager to better view the region of space, assigning another imager from a plurality of imagers to view the region of space, and combinations of these and other view improving actions.
The medium can have an orient component 16 which is adapted to cause the spatial location of a first coded data source to be recorded by the information system as part of the use data as a reference point. In a form of the product the causation here can occur when a coded data source specifies orienting. For example several coded data sources from a plurality of coded data sources can be dedicated reference points and located strategically in an environment.
In a form of the product the causation here can occur via interaction between the medium and the use data even though no coded data source specifies orienting. For example, the medium can cause coded data sources in an environment which the use data show to be stable to be recorded as reference points.
The medium can have a view component 23 which is adapted to cause a change in the collective field of view. In a form of the product a coded data source can specify a change in the collective field of view. In a form of the product the medium using the use data can specify a change in the field of view without any coded data source specifying the change.
The medium can have a locate component 17 which is adapted to cause location of the first coded data source relative to at least one reference point. In a form of the product the first coded data source can specify the locating. In a form of the product the medium using the use data can cause the locating without any coded data source specifying the locating.
The medium can have a track component 22 which is adapted to cause a tracking time series of locations of the first coded data source to be recorded by the information system as part of the use data. In a form of the product the first coded data source can specify the tracking.
In an example, a person can change the position of the first coded data source in the first field of view. The first data can be the position of the first coded data source. The first output data can be a display of a cursor tracking the positions of the code region. In another example where a person changes the position of the first coded data source in the first field of view, the first output data can control a process. The process can be motions of a device.
In a form of the product the medium using the use data can specify the tracking. For example, if a coded data source is located near a sensitive part of an environment at a time, then the medium can cause the later locations of that coded data source to be tracked at later times.
The medium can have a confirm component 18 which is adapted to cause determination that the tracking time series and the first data are consistent.
The medium can have a coordinate component 24 which causes the information system to use the use data to cause coordination of at least some imagers from the plurality of imagers. The view component and the confirm component can be components of the coordinate component.
The coordinate component can cause analysis of use data to oversee the actions of imagers and medium components. The coordinate component can cause management of the actions of the imagers via the output component and can cause management of actions of the medium components.
The coordinate component can cause variation of all of the variable elements of the imagers. For example the coordinate component can cause adjustment of the focus of an imager to optimize resolution.
The coordinate component can cause changes in the field of view of an imager and changes in the collective field of view. The coordinate component can cause at least a first imager to scan over a first field of view.
The coordinate component can cause assignment of a specific imager to specific coded data source. The coordinate component can cause passing on of the assignment from a first imager to a second imager when the second imager can better detect light from the coded data source. The coordinate component can cause use of extrapolation to assign an imager to pick up a coded data source as it returns from being out of sight of the imagers.
The coordinate component can cause changes in illumination of coded data sources. The coordinate component can cause modulation of the illumination to help resolve coded data sources over background light.
The medium can have an optimize component 25 which causes generation of an optimum path from the first coded data source to a target location, when the use data specifies optimizing.
The medium can have a vary component 26 which causes variable data to be recorded as part of the use data, when the first data specifies variation. The variable data can be part of the first data. The variable data can be caused by the region component of the medium to be imaged from a region of space specified by the first data. The first data can specify that a time series of values of the variable data be recorded as part of the use data.
The medium can have a control component 27 which causes generation of a control signal, when first data specifies control. The control signal can interact with an agent associated with the first data. An agent associated with the first data can be a being or a device. An agent can be identified by the first data. An agent can change the first data. The control signal can be electrical, photonic, visual, audible, tactile, and any other form useful to the being or device comprising the agent.
In an example, variable data can indicate the value of a property (temperature for example) of a process. The control signal can be input to a control device controlling the process. The control device can use the control signal to change the process accordingly.
Light from any first coded data source can represent first data by means of various physical properties of light in fixed, variable, and modulated modes. These physical properties of light comprise intensities, frequencies, phases, polarizations, entanglements, blink rates, decay times, external shapes, internal shapes, linear motions, rotational motions, strain motions, distances from at least one reference point, and combinations of two and more physical properties such as these. First data can be represented by a pattern comprising these physical properties in fixed, variable, and modulated modes.
Light from any first coded data source can have various origins such as light reflected from ambient sources, a light source at the coded data source, light emitted after energizing by suitable radiation, light with a characteristic decay time emitted after energizing by suitable radiation, a light source adjacent to the imager illuminating the coded data source, and combinations of these.
Light from any first coded data source is not limited to visible light. For example, infrared can be used, and millimeter and longer wavelengths can be used. Light can be radiating energy from any portion of the electromagnetic spectrum which can provide the functions required here. Other forms of radiating energy—such as acoustic energy—which can provide the functions required here are included in the meaning of “light” here.
The imager can be the dual mode imager of patent application PCTUS/01/13742 filed 30 Apr. 2001 and published as WO 01/84475 A1 08 Nov. 2001. Coded data sources 41, 51 which work well with the dual mode imager have retro-reflecting regions 42, 44, 52, 54 which are detected by the locate mode of the imager and have color regions 43, 53 which represent data and are detected by the react mode of the imager. A size differential between the retro-reflecting bands defines a direction 45, 55. Other imagers and other forms of coded data sources can be used.
The coordinate component of the medium can cause a coded data source to be illuminated by light with specific properties, and this light can comprise the locate light for a dual mode imager. The coordinate component can cause this light to follow a moving coded data source.
The imager can have several elements which selectively detect portions of a range of values of a physical property of light from a coded data source, with the several portions detected by the several imager elements being combined to detect the full range of the physical property of light without forming an image of the coded data source.
At least some imagers from the plurality of imagers can be incorporated in a flexible sheet. At least part of the medium can be incorporated in a flexible sheet. At least part of the information system can be incorporated in the flexible sheet. At least some coded data sources from the plurality of coded data sources can be incorporated in the flexible sheet. Various combinations of these elements can be incorporated together in a flexible sheet. Power sources can also be incorporated in the flexible sheet.
A “signal” from a first product part to a second product part and a first product part being “signal connected” with a second product part here, and throughout, mean that a first physical state of the first product part causes a second physical state of the second product part. This can occur by various direct causal means and can occur by any of various transmission means. Transmitted signals can be any of various point-to-point and broadcast forms of energy transmission such as wireless and via wires, cables, and fibers. Parts of transmitted signals can reside with one form of the transmitted signal, parts can reside with a second form of transmitted signal, and parts can reside with various combinations of transmitted signals.
The several causes here can act via any of various processing modes. The processing can utilize configured processing elements such as fixed circuits, can utilize configurable processing elements such as field programmable gate arrays and neural networks, can utilize instructions in a data-bearing medium, and can utilize combinations of these. The processing can be stand alone, can act via a local information system, can act via a networked information system, and can act via combinations of these.
This application claims benefit of U.S. provisional application 60/256,086 filed 15 Dec. 2000.
