DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIG. 1, a diagram is shown illustrating a suction cup camera 100 in accordance with an embodiment of the present invention. In one example, the suction cup camera 100 may be implemented as a small, compact camera that may be easily attached in any location. In one example, the suction camera 100 may be small enough to fit in the palm of a hand. The suction cup camera 100 may comprise a suction cup 102 with an aperture 104, a housing 106, and a camera 108. The aperture 104 generally passes completely through the back of the suction cup 102. The housing 106 may be attached at a rear side of the suction cup 102. The camera 108 may be disposed within the housing 106. The camera 108 may be attached to the suction cup 102 such that images may be captured through the aperture 104 and a surface to which the suction cup 102 is attached. The housing 106 is structured to allow pressure to be applied for attaching the suction cup 102 to a surface without affecting the camera 108.
The camera 108 generally comprises a body 110 and a lens assembly 112. The body 110 generally comprises electronic and/or mechanical parts (e.g., circuit boards, shutter, actuators, etc.) of the camera 108. The lens assembly 112 generally comprises the optical components (e.g., lens, iris diaphragm, etc.) of the camera. In one example, the lens assembly 112 may be configured to be mounted within the aperture 104 of the suction cup 102 such that camera 108 does not interfere with the suction cup 102 forming a vacuum with the surface to which the suction cup 102 is attached. In general, the suction cup 102 attaches the camera 108 to the surface when a user presses the suction cup 102 against the surface.
The camera 108 may be battery powered and include support for wireless communication by one or more wireless protocols such as Bluetooth, ZigBee, IEEE 802.11, IEEE 802.15, IEEE 802.15.1, IEEE 802.15.2, IEEE 802.15.3, IEEE 802.15.4, IEEE 802.15.5, and IEEE 802.20. The camera 108 may also include support for communicating using one or more of the universal serial bus protocols (e.g., USB 1.0, 2.0, 3.0, etc.). The camera 108 may also be configured to be powered via the USB connection. However, other communication and/or power interfaces may be implemented accordingly to meet the design criteria of a particular implementation.
Referring to FIG. 2, a diagram is shown illustrating a suction cup camera 200 in accordance with another embodiment of the present invention. In one example, the suction cup camera 200 may comprise a larger, more robust suction cup camera. For example, the suction cup camera 200 may be utilized in commercial and/or industrial environments. The suction cup camera 200 may comprise a housing 202, a pad 204, and a pump 206. The pad 204 may be formed, in one example, using a rubber material. However, other materials may be used to form the pad 204 to meet the design criteria of a particular implementation. The pump 206 generally includes a plunger 208. The pump 206 may also have a vacuum release valve (not shown). The pump 206 is generally configured to allow a person to attach the suction cup 200 to a surface by holding the pump 206 as a handle and pressing the plunger 208 to create a vacuum between the pad 204 and the surface to which the suction cup camera 200 is to be attached.
The pad 204 generally includes a first aperture 210 and a second aperture 212. The first aperture 210 may be used as an inlet port for the pump 206. The second aperture 212 may be configured to allow attachment of a camera 220 to a rear side of the pad 204 within the housing 202. When the camera 220 is mounted to the pad 204, a lens assembly 222 and the aperture 212 are generally aligned. The camera 220 may be attached such that the camera 220 may capture still and/or video images through the surface to which the suction cup camera 200 is attached.
The camera 220 further includes a body 224 that may comprise a circuit board with the electronics and mechanical components of the camera 220. The camera 220 may be battery powered and include support for wireless communication by one or more wireless protocols such as Bluetooth, ZigBee, IEEE 802.11, IEEE 802.15, IEEE 802.15.1, IEEE 802.15.2, IEEE 802.15.3, IEEE 802.15.4, IEEE 802.15.5, and IEEE 802.20. The camera 220 may also include support for communicating using one or more of the universal serial bus protocols (e.g., USB 1.0, 2.0, 3.0, etc.). The camera 220 may also be configured to be powered via the USB connection. However, other communication and/or power interfaces may be implemented accordingly to meet the design criteria of a particular implementation. In one example, connections to the camera 220 may be made using connectors mounted in the housing 202.
Referring to FIG. 3, a diagram is shown illustrating a suction cup camera 300 in accordance with yet another embodiment of the present invention. In one example, the suction cup camera 300 may comprise a housing 302, a pad 304, an actuator 306, and a lever 308. The pad 304 may be formed, in one example, using a rubber material. However, other materials may be used to implement the pad 304 to meet the design criteria of a particular implementation. The lever 308 generally includes a cam surface 310. The cam surface 310 may be configured to press against a raised structure 312 on a side surface of the housing 302.
As the lever 308 is rotated from being perpendicular to a front edge of the suction cup camera 300 to being parallel to the front edge of the suction cup camera 300, the cam surface 310 and raised structure 312 cause a pivot of the lever 308 to move away from the front surface of the suction cup camera 300. The pivot of the lever 308 is attached to the actuator 306 and the actuator 306 is attached to the pad 304. As the pivot moves away from the front edge of the suction cup camera 300, the actuator 306 and, consequently, the pad 304 are also moved away from the front edge of the suction cup camera 300. With the suction cup camera 300 held against a surface, the movement of the pad 304 away from the front edge of the suction cup camera 300 generally creates a vacuum between the pad 304 and the surface to which the suction cup camera 300 is to be attached. In one example, the lever 308 and the raised structure 312 are duplicated on opposite sides of the housing 302 such that the actuator 306 may move smoothly back and forth to attach and release the suction cup camera 300 from the surface. The two levers 308 may be coupled to one another for ease of use.
The pad 304 may include an aperture 314. The aperture 314 is generally aligned with a passage through the actuator 306. A camera 320 may be attached to a rear portion of the actuator 306 such that a lens assembly of the camera 320 is disposed within the passage through the actuator 306 and aligned with the aperture 314. The camera 320 may be attached such that the camera 320 may capture still and/or video images through a surface to which the suction cup camera 300 is attached. A body 322 of the camera 320 may include a circuit board with the electronics and mechanical components of the camera 320. The camera 320 may be battery powered and include support for wireless communication by one or more wireless protocols such as Bluetooth, ZigBee, IEEE 802.11, IEEE 802.15, IEEE 802.15.1, IEEE 802.15.2, IEEE 802.15.3, IEEE 802.15.4, IEEE 802.15.5, and IEEE 802.20. The camera 320 may also include support for communicating using one or more of the universal serial bus protocols (e.g., USB 1.0, 2.0, 3.0, etc.). The camera 320 may also be configured to be powered via the USB connection. However, other communication and/or power interfaces may be implemented accordingly to meet the design criteria of a particular implementation.
Referring to FIG. 4, a diagram is shown illustrating a suction cup camera 400 in accordance with still another embodiment of the present invention. In one example, the suction cup camera 400 may comprise a housing 402, a pad 404, an actuator 406, and a knob 408. In one example, the pad 404 may be made of rubber. However, other materials may be used to form the pad 404 accordingly to meet the design criteria of a particular implementation.
In one example, the suction cup camera 400 may be configured to attach to a surface when the knob 408 is turned in either a clockwise or counter-clockwise direction. The suction cup camera 400 may be further configured to be easily removed from the surface after rotating the knob 408 in the opposite (e.g., counter-clockwise or clockwise) direction. For example, the knob 408 may be engaged with the actuator 406 via a number of threads such that as the knob 408 is rotated in one direction the actuator 406 is moved away from the front edge of the suction cup camera 400 and when the knob 408 is rotated in the opposite direction the actuator 406 is moved toward the front edge of the suction cup camera 400. In one example, the size and number of the threads may be selected to allow attachment of the suction cup camera 400 with less than a full turn (e.g., 30°, 45°, 60°, 90°, etc.) of the knob 408.
The actuator 406 may be attached to the pad 404 such that as the actuator 406 is moved away from the front edge of the suction cup camera 400, the pad 404 is also moved away from the front edge of the suction cup camera 400 and, consequently, away from the surface to which the suction cup camera 400 is to be attached. With the suction cup camera 400 held against the surface, the movement of the pad 404 away from the front edge of the suction cup camera 400 generally creates a vacuum between the pad 404 and the surface to which the suction cup camera 400 is to be attached.
The pad 404 may include an aperture 410. The aperture 410 is generally aligned with a passage 412 through the actuator 406. A camera 420 may be attached to a rear portion of the actuator 406 such that a lens assembly 422 of the camera 420 is disposed within the passage 412 of the actuator 406 and aligned with the aperture 410. The camera 420 may be attached such that the camera 420 may capture still and/or video images through a surface to which the suction cup camera 400 is attached. A body 424 of the camera 420 may include one or more circuit boards with the electronics and mechanical components of the camera 420. The camera 420 may be battery powered and include support for wireless communication by one or more wireless protocols such as Bluetooth, ZigBee, IEEE 802.11, IEEE 802.15, IEEE 802.15.1, IEEE 802.15.2, IEEE 802.15.3, IEEE 802.15.4, IEEE 802.15.5, and IEEE 802.20. The camera 420 may also include support for communicating using one or more of the universal serial bus protocols (e.g., USB 1.0, 2.0, 3.0, etc.). The camera 420 may also be configured to be powered via the USB connection. However, other communication and/or power interfaces may be implemented accordingly to meet the design criteria of a particular implementation. In one example, connections to the camera 420 may be made using connectors that may be accessed through openings in the knob 408.
Embodiments of the present invention may also be configured to determined when a device implemented in accordance with the present invention is attached to a surface. For example, with reference to FIG. 4, a sensor 430 may be implemented to detect when a suction cup camera in accordance with the present invention is attached to a surface. In one example, the sensor 430 may be configured to provide a signal or actuate a switch when the associated suction cup camera is attached to the surface. In one example, the signal or switch may be configured to control power to the associated suction cup camera. For example, battery life may be extended by controlling power such that the camera is energized only when attached to a surface. In another example, the signal or switch may be configured to produce a warning or alarm indicating that the associated suction cup camera is no longer attached to the surface. In yet another example, the signal or switch could be configured to switch the associated suction cup camera between an unattended (or automatic) mode and an attended (or user controlled) mode. The sensor 430 may be implemented using, for example, a switch, a mechanical linkage, a proximity detector, a pressure sensor, a sensor configured to detect a change in refractive index, a photovoltaic sensor, or any other appropriate device. Although the sensor 430 is shown in the context of the embodiment illustrated in FIG. 4, it will be apparent to those of ordinary skill in the art that embodiments of the sensor 430 may be implemented for use with the embodiments illustrated in FIGS. 1-3.
Referring to FIG. 5, a diagram is shown illustrating a camera 500 that may be used to implement a suction cup camera in accordance with an embodiment of the present invention. In one example, the camera 500 may be slightly larger than a U.S. quarter dollar coin. The camera 500 may comprise a circuit board 502, a circuit board 504 and a lens assembly 506. The circuit boards 502 and 504 may contain the camera electronics (e.g., embedded processor, digital signal processor(s), memory, communication interfaces (e.g., wired, wireless, etc.), and image sensor (e.g., CCD)). In one example, the lens assembly 506 may implement a pan/tilt/zoom lens. The circuit boards 502 and 504 may contain the features needed to control the pan/tilt/zoom lens. The lens assembly 506 may be mounted to the circuit board 504 in such a manner as to allow the lens assembly 506 to support the weight of the circuit boards when mounted by a suction cup to a surface. In one example, the circuit board 504 may also include a button (or switch) 508 and a connector 510. The button 508 may be configured for taking pictures manually. The connector 510 may be configured to connect the camera 500 to other devices (e.g., a USB connector). However, other camera configurations may be implemented to meet the design criteria of a particular implementation.
Referring to FIG. 6, a block diagram is shown illustrating an example implementation of a camera system 600. In one example, the electronics of the camera system 600 may be implement as one or more integrated circuits. For example, an application specific integrated circuit (ASIC) or system on chip (SOC) may be used to implement the camera system 60. In one example, the camera system 600 may comprise a camera chip (or circuit) 602, a lens assembly 604, an image sensor 606, an audio codec 608, dynamic random access memory (DRAM) 610, FLASH memory 612, one or more serial interfaces 614, an interface 616 for connecting to or acting as a USB host, a wireless interface 618, an interface for connecting to a removable media (e.g., SD, SDXC, etc.) 620, an interface for communicating with portable touchscreen device 622, and an interface for communicating with a television 624. The main camera circuit 602 may include a number of modules including a pulse width modulation (PWM) module, a real time clock and watch dog timer (RTC/WDT), a direct memory access (DMA) engine, a high-definition multimedia interface (HDMI), an LCD/TV/Parallel interface, a general purpose input/output (GPIO) and analog-to-digital converter (ADC) module, an infra-red (IR) remote interface, a secure digital input output (SDIO) interface module, an SD card interface, an audio I2S interface, an image sensor interface, and a synchronous data communications interface (e.g., IDC SPI/SSI). The circuit 602 may also include an embedded processor (e.g., ARM, etc.), an image digital signal processor (DSP) and a video DSP. The circuit 602 may be configured (programmed) to control the lens assembly 604 and receive image data from the sensor 606.
Embodiments of the present invention generally provide a digital camera that may be attached simply to any surface and capture images through the surface to which the camera is attached. In general, the surfaces to which the camera is attached may be transparent or translucent. The transmission characteristics of the particular surface to which the camera may be attached may be determined by the spectral sensitivity of the particular image sensor implemented. For example, a camera with an infra-red (IR) sensitive sensor may capture images through a surface that is transparent to IR wavelengths, but appears opaque in the visible light spectrum. A suction cup camera in accordance with embodiments of the present invention may (i) be removably attached to any smooth surface, (ii) allow placing a camera on any window, (iii) allow viewing through a hotel room door peep sight without standing near the door, (iv) allow moving a dash cam between multiple cars, (v) alert a user if the device falls off a surface to which the device is attached, and/or (vi) allow images to be captured through the surface to which the suction cup camera is attached.
