摘要: A controller for a camera crane has a rocker button pivotally supported in or on a controller housing about a first pivot axis. A shaft of an electrical component, such as a variable resistor, is on a second pivot axis spaced apart from the first pivot axis. An arm is attached to the shaft. A spring urges the arm to a center position. Movement of the rocker button moves the arm. Due to the offset of the first and second pivot axes, movement of the rocker button results in proportionally reduced movement of the shaft of the electronic component. Smooth crane arm movements are readily achieved as the controller is less sensitive to the operators hand or finger movements.

摘要: An accessory for use on a camera crane has a first plate attachable to an end of the camera crane arm. A second plate is pivotally attached to the first plate and moveable into a first position and into a second position perpendicular to the first position. First and second latches secure the second plate into the first and second positions, respectively. The accessory allows a camera head on a camera crane arm to be quickly and easily reoriented.

摘要: A method for stabilizing a camera platform includes generating a first signal from a platform sensor, such as a gyro sensor, on the camera platform indicative of a change in angular position of the camera platform. The first signal is added to a control signal provided from a camera platform position controller, typically operated by the camera operator. A first correction value based on the sum of the first signal and the control signal is calculated. A second correction value is calculated based on a signal from an encoder associated with a motor linked to the camera platform. Adding the first correction value and the second correction value provides a motor control signal which is amplified and used to control the motor.

摘要: A flashlight includes a first or top section attached to a second or base section. The top section has one or more elements that are axially moveable relative to the base section, for focusing light. This movement may be achieved, for example, by having the top and base sections joined via screw threads, and by rotating one section relative to the other. One or more lenses are supported in the top section. An LED or other light source is supported on a base or heat sink on the base section. As the sections move relative to each other, a switch is actuated turning the LED on, and the lens moves relative to the LED, focusing light from the LED. The base section has a housing forming a battery compartment. Electronic components are encapsulated in a potting compound, such as thermally conductive epoxy, to improve heat transfer from the components, and to better resist environmental affects.

摘要: A shock and vibration isolator for a movie or video camera has a vertical axis system including a base, an arm pivotably attached to the base, and at least one spring connected to the base and to the arm. One or more dampeners are connected to the base and to the arm. A horizontal axis system is supported by the vertical axis system. A leveling linkage connects the vertical and horizontal axis systems. The leveling linkage has adjustment features that allow for compensation of camera lens angulation caused by movement of the camera supported on a vehicle rolling over rough or uneven ground.

摘要: A flashlight has a lens or lenses moveable relative to one or more LED or other light source. The beam of light provided by the LED can be focused and provides a uniform light pattern across the range of focus. The lenses are supported on a front housing section and the LED is supported on a back housing section threaded onto the front housing section. Twisting the front housing section closes a switch providing power to the LED, to turn the flashlight on. One or more circuit modules within the flashlight provides various operating modes including an automatic shut-off timer, to preserve battery life, a dimmer controlled by turning an end cap, a blinking function, a momentary bright function, and/or a current control function to provide maximum brightness regardless of battery condition.

摘要: An improved hydraulic valve for a camera dolly includes Teflon inserts around a valve pin to reduce vibration and noise. The ratio of movement between the boom control, which controls the up and down movement of the arm on the camera dolly, and opening and closing of the hydraulic valve, is increased to reduce the sensitivity of the valve to boom control movement. The boom control includes ready up and ready down detents which provide the user a tactile indication of where to position the boom control for immediate up or down movement.
