DETAILED DESCRIPTION
Description
Embodiments of a novel media gate are described that not only adapt to different lane widths, but also extend and retract in a manner that maintains a horizontal attitude of an attached media display throughout the extension/retraction process. This maximizes exposure of media to people at or near the gate.
In some embodiments, a gate extension and retraction apparatus may include a housing, a digital display device, at least one extension arm coupled to the housing and to the digital display device, an analytical unit, the analytical unit, and/or the analytical unit. The analytical unit may include a controller, the analytical until coupled to the digital display device and the controller coupled to the extension arm.
In some embodiments, the apparatus may include logic to operate environmental sensors to identify demographic attributes of a proximate person to the digital display device and to locate digital content associated with the demographic attributes and to cause display of the digital content on the digital display device. The apparatus may include logic to operate the controller to operate the extension arm to lift the digital display device from a first gate position blocking a retail lane to a second gate position permitting egress by the proximate person to the digital display device from the retail lane upon receiving a purchase confirmation from a point of sale device. The apparatus may include a camera that is one of the environmental sensors operated by the analytical unit, and/or a motion detector that is one of the environmental sensors operated by the analytical unit. The motion detector may be configured to signal to the analytical unit that the proximate person to the digital display device is passing underneath the digital display device and/or the analytical unit, and logic to generate an alarm in response thereto.
In some embodiments, the digital display device may include two opposing digital display surfaces. The apparatus may include a speaker operable by the analytical unit.
In some embodiments, may include an active actuator and a passive actuator are each pivotally coupled to the extension arm. An electromagnetic toggle may be configured to secure the extension arm to an active actuator while electrical power is available to the active actuator and/or the electromagnetic toggle configured to release the extension arm from the active actuator when the electrical power is not available to the active actuator.
In some embodiments, such a extension and retraction apparatus may further include a near field wireless communicator. In some embodiments, such a extension and retraction apparatus may further include a fire panel interface.
The orientation of the display may remain constant either in landscape or portrait orientation. Whether the display orientation is portrait or landscape is configurable according to the lane width.
Generally, a plurality of mechanical supports and actuators are employed to support and move the gate. These arms are configured to move at different speeds and angles, maintaining a supported media gate in a horizontal attitude relative to the floor. In one embodiment, the mechanical supports and actuators comprise two telescoping tubes where the telescoping of each tube is driven by linear actuators that operate to telescope one tube at a different rate than the other.
The media gate may comprise a camera to capture video of people waiting behind (e.g., near) the gate. System logic may analyze video or images from the camera to ascertain attributes of the people for purposes of targeted advertising. Attributes may include the person's gender, approximate age, clothing, and whether they are accompanied by children or infants, for example.
The media gate may comprise a Wi-Fi access point which may communicate with mobile devices of people near the gate, for example to suggest promotions and coupon deals relevant to the detected attributes of those people.
DRAWINGS
FIG. 1 illustrates an embodiment of a digital media gate 100. The digital media gate 100 comprises a display screen 120, tapered corner 102, upper support actuator 104, lower support 106, upper support 108, lower support actuator 110, top edge 112, housing 122, and inner edge 114. The digital media gate 100 may also include other features not necessary to this description.
The display screen 120 is retractable into and extendable from a housing 122. During extension and retraction, the display screen 120 remains horizontal to a floor below the display screen 120. An upper support actuator 104 controls an upper support 108 of the display screen 120, and a lower support actuator 110 controls a lower support 106 of the display screen 120. The lower support actuator 110 and the lower support 106 are configured such that the upper support actuator 104 extends away from an inner edge 114 of the housing 122 and the lower support actuator 110 extends toward the inner edge 114, forming a crossover configuration of the upper support actuator 104 and the lower support actuator 110.
The display screen 120 is adapted with pivots 118 that enable the lower support actuator 110 and the upper support actuator 104 to maintain the display screen 120 horizontal to the floor during extension from and retraction into the housing 122. The upper support actuator 104 and the lower support actuator 110 are operated at different extension rates to maintain the horizontal aspect of the display screen 120.
The display screen 120 may be fixed in a landscape orientation (illustrated) or a portrait orientation, depending on the width of a retail lane that the display screen 120 blocks when extended. In one embodiment, a tapered corner 102 is formed between the inner edge 114 and the top edge 112. In the retracted position the display screen 120 fills the tapered corner 102 so that the right angle removed from the housing 122 by the tapered corner 102 is replaced by the upper right corner of the display screen 120.
In one embodiment the digital media gate 100 comprises logic to implement a learn and jog function. Upon installation of the digital media gate 100, the installer “jogs” both the rotational (angular) actuator (which orients the display screen 120) and the linear actuators (that raise or lower the display screen 120) to the “down” (blocking the retail lane) position. The installer then activates the learning function of the digital media gate 100. The installer then jogs both the rotational actuator and the linear actuators to the screen up (retracted from blocking the retail lane) position. The installer then ends learning mode. The digital media gate 100 may then autonomously transition between the up and down positions in normal operation.
FIG. 2 illustrates an embodiment of a digital media gate 200 comprising an environmental response system. The display screen 120 comprises a camera 208, microphone 210, and wireless communication logic 212. Each of these elements coupled to an analytic system 206, which may be housed in the housing 122 or external to the housing 122.
A mobile device 202 carried by a shopper 204 (not to scale) may communicate with the wireless communication logic 212 and in this manner receive and display to the shopper 204 coupons, promotions, advertisements, and other types of media from the analytic system 206. The analytic system 206 comprises a controller 216 for controlling extension and retraction of the display screen 120. The analytic system 206 may also communicate media to the speaker 214. A selection process by the analytic system 206 for the media may be influenced by environmental inputs from the camera 208 and microphone 210 (one or both). Some embodiments of the digital media gate 200 may utilize other sensors as well, such as near field scanners (e.g., RFID readers).
The media may be communicated to the shopper 204 in a number of ways, including but not limited to Wi-Fi, NFC (near field communication), QR codes, and beacon technology.
Although illustrated as elements of the display screen 120, in some embodiments of the digital media gate 200 any or all of the camera 208, microphone 210, and wireless communication logic 212 may be included on, within, or with the housing 122. The speaker 214 may in some embodiments be included in the display screen 120.
A signal from the point of sale device 218 indicating purchase confirmation by the shopper 204 may cause the analytic system 206 to operate the controller 216 to operate the media gate extension and retraction assembly 518 to lift the display screen 102 from blocking egress from the retail lane by the shopper 204. Logic of the analytic system 206 may cause the controller 216 to operate the media gate extension and retraction assembly 518 such that the display screen 102 is retracted (lifted) while maintaining a horizontal aspect, i.e., the display screen 102 stays horizontal with respect to a floor of the retail lane.
FIG. 3 illustrates an embodiment of a digital media gate 300 comprising an environmental response system. The digital media gate 300 is configured for manual override in the event of a power failure. When the display screen 120 is in the down position (obstructing the retail lane) and there is a power failure, a shopper 204 or other party may pick up the screen with (for example) less than 25 LBS force. One or more passive gas actuator 502 will assist to position the display screen 120 in the up (retracted) position.
The analytic system 206 may interface to a fire panel. There is a choice of normally open or normally closed contacts between the analytic system 206 and the fire panel 304. The selection depends on the specific make and model of the fire panel 304. When the controller 216 receives a signal from the fire panel 304, the controller 216 automatically opens (lifts) the display screen 120. It will not respond to any user request unit the signal from the fire panel 304 is neutralized. An audible message may be played by the analytic system 206 through the speaker 214 enunciating for example “emergency exit here”, repeatedly until the fire panel 304 signal is neutralized.
The display screen 120 may be be double sided, i.e. one display area facing toward and away from shoppers in the retail lane.
When the display screen 120 is in the down (extended) position, a motion sensor 302 (e.g., an acoustic sensor) may monitor an area under the display screen 120. If the shopper 204 tries to pass under the display screen 120, the digital media gate 300 may generate an alarm, e.g., via the speaker 214 or via an electronic message to staff of the store.
When the display screen 120 is in the up (retracted) position, the motion sensor 302 monitors an area (e.g., 24′′) in front (toward the shopper 204) of the display screen 120 and an area (e.g., 24′′) behind the display screen 120. If the motion sensor 302 senses the presents of an object in either area, any extension of the display screen 120 that is under way is suspended or prevented until the area is cleared. An audible alert may sound via the speaker 214 as well.
FIG. 4 illustrates an embodiment of a media selection process 400 carried out by the analytic system 206. An image or video of the retail lane controlled by the digital media gate 200 is recorded (block 402). The analytic system 206 analyzes the image for the presence of one or more shopper 204 (opening loop block 404).
There are various ways that recording of the image may be triggered. Proximity sensors that detect motion, pressure, or presence are one example. Another way is continuously record and analyze video or photos.
A z-order is assigned to the detected shopper 204 (block 406). The z-order identifies the shopper's order in line based on their depth in the recorded image. The analytic system 206 also roughly classifies the shopper from their representation in the image (block 408). Example rough classifications are gender, age, and whether they are accompanied by children or infants.
When the analytic system 206 can no longer identify additional shoppers, it selects best-fit media to communicate to the display screen 120 and to the speaker 214.
In some embodiments, the video media that is selected for communication to the display screen 120 is media deemed most relevant to the shopper 204 having the lowest assigned z-order, based on that shopper's rough characteristics (block 410). In another embodiment, the shopper 204 can speak to the microphone 210 to identify products or services, and the analytic system 206 will select media for the display screen 120 accordingly. In some embodiments, the video media that is selected for communication to the display screen 120, and/or to the speaker 214, is media deemed most relevant to the a set of N shoppers having the lowest assigned z-orders, based on that shopper's rough characteristics. The video media selected by the analytic system 206 for the display screen 120 may be silent video associated with the characteristics of the lowest z-order shopper, while the audio media selected for the speaker 214 may be associated with group characteristics of a set of N>1 shoppers having the lowest z-orders. In some cases the audio media may be generic, meaning not based on characteristics of the shoppers in the image, while the video media selected is associated with characteristics of the lowest value z-order shopper, or a set of N>1 lowest value z-order shoppers.
FIG. 5 illustrates an embodiment of a media gate extension and retraction assembly 518.
The media gate extension and retraction assembly 518 comprises a passive gas actuator 502, a powered linear actuator 504, a linear actuator chassis pivot 506, a linear actuator arm pivot 508, an electromagnet 510, an electromagnet toggle 512, a gas actuator chassis pivot 514, and a gas actuator arm pivot 516.
The passive gas actuator 502 is a passive device, e.g., a gas spring, and the powered linear actuator 504 is an active device. The powered linear actuator 504 receives control signals from the controller 216 of the analytic system 206 and as well as provides feedback as to its position to the controller 216. Both the passive gas actuator 502 and the powered linear actuator 504 are fixed to the housing 122 and are permitted to pivot, as well as pivot with respect to the lower support 106 and upper support 108 as they both extend or retract. The passive gas actuator 502 pivots at the housing 122 at gas actuator chassis pivot 514, and at the support at gas actuator arm pivot 516. The powered linear actuator 504 pivots at the housing 122 at linear actuator chassis pivot 506 and at the support at linear actuator arm pivot 508.
The passive gas actuator 502 serves to offset the load of the display screen 120 that the powered linear actuator 504 is required to lift to extend the display screen 120. Similarly the passive gas actuator 502 offsets the force exerted by the display screen 120 on the powered linear actuator 504 as the display screen 120 is retracted.
Another mechanism involved in extending and retracting the display screen 120 is the electromagnet 510 and the electromagnet toggle 512. These serve as a failsafe mechanism in the event of a power failure. Specifically, if the display screen 120 is extended and there is a power failure the electromagnet 510 will release the electromagnet toggle 512. The electromagnet toggle 512 by distribution of its center of gravity rotates away from being engaged to the lifting mechanism (passive gas actuator 502 and powered linear actuator 504). This allows the display screen 120 to be lifted (retracted) manually, clearing the retail lane for emergency egress—with a lifting force of approximately (for some embodiments) 25 lbs. Once the power is restored, the controller 216 initiates a routine to identify the position of the display screen 120 and re-engage the electromagnet 510 and the electromagnet toggle 512.
FIG. 6 illustrates an embodiment of an analytic system 206 for a digital media gate.
Input devices 604 comprise transducers that convert physical phenomenon into machine internal signals, typically electrical, optical or magnetic signals. Signals may also be wireless in the form of electromagnetic radiation in the radio frequency (RF) range but also potentially in the infrared or optical range. Examples of input devices 604 are keyboards which respond to touch or physical pressure from an object or proximity of an object to a surface, mice which respond to motion through space or across a plane, microphones which convert vibrations in the medium (typically air) into device signals, scanners which convert optical patterns on two or three dimensional objects into device signals. The signals from the input devices 604 are provided via various machine signal conductors (e.g., busses or network interfaces) and circuits to memory 606.
The memory 606 is typically what is known as a first or second level memory device, providing for storage (via configuration of matter or states of matter) of signals received from the input devices 604, instructions and information for controlling operation of the CPU 602, and signals from storage devices 610.
Information stored in the memory 606 is typically directly accessible to the CPU 602 of the device. Signals input to the device cause the reconfiguration of the internal material/energy state of the memory 606, creating in essence a new machine configuration, influencing the behavior of the analytic system 206 by affecting the behavior of the CPU 602 with control signals (instructions) and data provided in conjunction with the control signals.
Second or third level storage devices 610 may provide a slower but higher capacity machine memory capability. Examples of storage devices 610 are hard disks, optical disks, large capacity flash memories or other non-volatile memory technologies, and magnetic memories.
The CPU 602 may cause the configuration of the memory 606 to be altered by signals in storage devices 610. In other words, the CPU 602 may cause data and instructions to be read from storage devices 610 in the memory 606 from which may then influence the operations of CPU 602 as instructions and data signals, and from which it may also be provided to the output devices 608. The CPU 602 may alter the content of the memory 606 by signaling to a machine interface of memory 606 to alter the internal configuration, and then converted signals to the storage devices 610 to alter its material internal configuration. In other words, data and instructions may be backed up from memory 606, which is often volatile, to storage devices 610, which are often non-volatile.
Output devices 608 are transducers which convert signals received from the memory 606 into physical phenomenon such as vibrations in the air, or patterns of light on a machine display, or vibrations (i.e., haptic devices) or patterns of ink or other materials (i.e., printers and 3-D printers).
The network interface 612 receives signals from the memory 606 and converts them into electrical, optical, or wireless signals to other machines, typically via a machine network. The network interface 612 also receives signals from the machine network and converts them into electrical, optical, or wireless signals to the memory 606.

Unless the context clearly requires otherwise, throughout the description and the claims, the words “comprise,” “comprising,” and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in the sense of “including, but not limited to.” Words using the singular or plural number also include the plural or singular number respectively, unless expressly limited to a single one or multiple ones. Additionally, the words “herein,” “above,” “below” and words of similar import, when used in this application, refer to this application as a whole and not to any particular portions of this application. When the claims use the word “or” in reference to a list of two or more items, that word covers all of the following interpretations of the word: any of the items in the list, all of the items in the list and any combination of the items in the list, unless expressly limited to one or the other.
“Logic” refers to machine memory circuits, non transitory machine readable media, and/or circuitry which by way of its material and/or material-energy configuration comprises control and/or procedural signals, and/or settings and values (such as resistance, impedance, capacitance, inductance, current/voltage ratings, etc.), that may be applied to influence the operation of a device. Magnetic media, electronic circuits, electrical and optical memory (both volatile and nonvolatile), and firmware are examples of logic. Logic specifically excludes pure signals or software per se (however does not exclude machine memories comprising software and thereby forming configurations of matter).
Those skilled in the art will appreciate that logic may be distributed throughout one or more devices, and/or may be comprised of combinations memory, media, processing circuits and controllers, other circuits, and so on. Therefore, in the interest of clarity and correctness logic may not always be distinctly illustrated in drawings of devices and systems, although it is inherently present therein.
The techniques and procedures described herein may be implemented via logic distributed in one or more computing devices. The particular distribution and choice of logic will vary according to implementation.

Hardware refers to logic embodied as analog and/or digital circuits. If an implementer determines that speed and accuracy are paramount, the implementer may opt for a hardware and/or firmware vehicle; alternatively, if flexibility is paramount, the implementer may opt for a solely software implementation; or, yet again alternatively, the implementer may opt for some combination of hardware, software, and/or firmware. Hence, there are several possible vehicles by which the processes described herein may be effected, none of which is inherently superior to the other in that any vehicle to be utilized is a choice dependent upon the context in which the vehicle will be deployed and the specific concerns (e.g., speed, flexibility, or predictability) of the implementer, any of which may vary.
