In reality, Americans seem to be pretty OK with drones. A poll conducted by Pew in March found that 65 percent of the country supported drone strikes of non-U. That number certainly skyrockets when the drones are used in search-and-rescue missions, to check out the damage of natural disasters, or to, say, deliver pizzas. His belief: Unmanned aircraft is the harbinger of great changes in the near future. Give it five to 10 years. And yet, it's hard for these drones not to just seem kind of nefarious.
Located near the center of the convention hall, not far from a netted off area replete with a flying drone obstacle course, is the Dreamhammer booth. With its chic white walls and tall beautiful women dressed in black, it has the look of an evil Apple store. Nelson Paez, the CEO of the company, fits the dress code perfectly. He towers over everyone else, his hair gelled, his goatee groomed, and his black pants tight.
His company makes operating software for drones, and his main client is the government. I ask if he ever loses sleep at night when he hears of drone strikes. You can use that to look at a porn site or a national security site. It's not up to Windows how it's used. Krot told the man. Angela Simmons caught fans by surprise on Jan.

In cases where the payload is not located at the desired center of gravity, the requirement to decrease its weight becomes more critical as it may affect the balance of the vehicle. Accordingly, it is desirable to mitigate the weight of an embedded camera and an associated camera assembly without affecting the quality of camera images. In addition to the weight consideration, there is a need for a UAV embedded camera to rotate and spin with a high degree of flexibility.
Prior art cameras employed with UAVs have limitations pertaining to spin and rotation. These limitations reduce the functionality of the camera. The limitations associated with cameras in UAVs, as described above, extends to all forms of vehicles, including, land, and air and sea vehicles.
The mounting assembly for an embedded camera should be configured to support a lightweight camera with full viewing across all viewing angles while mitigating exposure to external elements of the camera and its associated assembly. In one aspect of the invention, a camera mount is provided with a housing having two portions, a camera lens mounted to an external surface of both portions, and a camera body mounted within the housing. A yoke is located within the housing. The yoke is comprised of a stem connected to both a first leg and a second leg.
A tilt feedback device is mounted adjacent to one of the legs, and a tilt assembly is provided in communication with one of the legs of the yoke. The tilt assembly is in communication with a tilt feedback device. In addition, a pan assembly is provided external to the housing and in communication with a pan feedback device, and in communication with the stem of the yoke.
The combination of the pan and tilt devices in communication with the camera mount enable controlled movement of the camera about the respective axis. In another aspect of the invention, a camera mount is provided with a monocoque housing comprised of two portions.
A camera lens is mounted to an external surface of both portions. The camera lens is in communication with a camera body that is mounted within the housing. The camera body is in communication with a yoke, which is located within the housing.
The yoke has a stem that is connected to both a first leg and a second leg, and a tilt feedback device that is mounted adjacent to one of the legs. Each leg is pivotally attached to a corresponding portion of the housing.
A tilt assembly is provided within the housing in communication with one of the legs of the yoke and in communication with the tilt feedback device. In addition, a pan assembly is mounted external to the housing and in communication with a pan feedback device, and in communication with the stem of the yoke.
Other features and advantages of this invention will become apparent from the following detailed description of the presently preferred embodiment of the invention, taken in conjunction with the accompanying drawings.
A turret assembly is provided to accommodate a small and lightweight camera. The assembly is configured to be mounted on a vehicle, including, but not limited to a land based vehicle, a water based vehicle, or an aerial vehicle.
The features of the turret assembly include remote-feedback, a pan function, and a tilt function. In one embodiment, the pan function is servo-operated. The combination of the pan and tilt functions support both tilt and pan movement of the camera embedded within the turret assembly.
In one embodiment, the pan function includes a rotating vertically oriented camera yoke driven by a servomechanism via a chain or other positive drive means, such as a belt. To allow continuous rotation of the servo motor and permit the servo drive train to be geared up or down, including at least degrees of pan movement, without changing the desired camera rotation, the servo drive train is configured without a mechanical stop.
The servomechanism employed in the turret assembly is in communication with a positive tilt feedback device connected to the yoke in a manner that permits the positive tilt feedback device to communicate the tilt position of the camera. In one embodiment, the rotation configuration may be modified by including a gear or lever arm between the yoke and the potentiometer to change the feedback ratio or gear ratio, of the position feedback device, e.
In a further embodiment of the turret assembly, a tilt function to the camera is provided to rotate the camera with respect to a horizontal axis defined by connection points of a U-shaped yoke to the turret. In one embodiment, a control cable is employed to support the tilt function.
The control cable, or an alternate tilt function supporting element, is routed to the camera turret through a sheath which passes through the center of rotation of the yoke, thus permitting the yoke to turn, i. The driving end of the tilt function supporting element is attached to the inside of the turret shell offset from a vertical axis of the yoke.
A pull or push on the cable will result in a rotational displacement of the camera about the horizontal axis defined by connection points of a U-shaped yoke to the turret. In one embodiment, a drive end of the control cable may be attached directly to either a servo-driven crank handle, or to a bell crank mechanism.
For example, the attachment to the servo-driven crank handle may be desirable for a short stroke application, and the attachment to a bell crank mechanism may be desirable for a long stroke application.
The turret mounted camera assembly further comprises a camera connection harness having electrical wiring to provide power to the camera, as well as cable connection for signal transmission to and from the camera. In one embodiment, the camera may support wireless communication. Such an embodiment would accommodate removal of the requirement for the signal cable. The camera mount assembly has two primary components.
A first component is employed for controlling tilt movement of a camera mounted in the assembly, and a second component is employed for controlling pan movement of the camera assembly. The components that control tilt movement are local to the camera and are mounted in spherical monocoque housing.
The components that control pan movement are housed in an assembly external to the monocoque housing, and are in direct communication with the housing. As shown the spherical portion is comprised of two halves and , also known as hemispheres.
A camera is mounted to both halves and of the sphere. More specifically, as shown from outside the housing, the camera lens is mounted to the spherical portions and with a set of attachment elements and on the first half , and attachments elements and on the second half The invention should not be limited to four attachment elements, as in one embodiment, there may be a reduced or increased quantity of attachments elements.
An opening to the interior of the housing is provided in the form of a brushed opening This opening is coaxial with the mid-section of the camera. In one embodiment, the brushed opening may be replaced with a water-tight seal, such as a silicone cuff seal, or an alternative element for enclosing the opening of the housing. In addition to the opening , each half and of the housing is provided with a bearing to pivotally attach a yoke to each hemisphere.
On the exterior side of each hemisphere a pivot shoulder is provided. In one embodiment, the pivot shoulder is in the form of a bolt. More specifically, pivot shoulder is provided on spherical portion , and a second pivot shoulder not shown is provided on spherical portion In one embodiment, each of the pivot shoulders is on diametrically opposite sides of the spherical portion Accordingly, a sphere comprised of two attached hemispheres and is provided to house the camera and an associated camera tilt mechanism.
As shown, a bearing is provided in communication with the associated pivot shoulder not show. A pin extends from the bearing toward a center of the sphere.
The pin is provided to engage with a tilt assembly. More specifically, the tilt assembly employs a yoke, and the pin is provided to engage a fork coupling mechanism that rotates a tilt potentiometer local to the yoke.
In one embodiment, a second bearing and an associated pin are provided on the second hemisphere to secure an opposite leg of the yoke to the second hemisphere. As shown, a yoke is provided with a central shaft and two legs and extending from the central shaft Each of the two legs and is provided with an opening to receive a securing element. More specifically, the securing element attaches each leg to the respective hemisphere. As shown, a first enclosure with a gear train and motor is in communication with one of the legs of the yoke through a sprocket in communication with a gear and associated drive train In one embodiment, the first enclosure houses the servo motor that provides tilt to the assembly.
