242 results about "Trim tab" patented technology

Trim tabs are small surfaces connected to the trailing edge of a larger control surface on a boat or aircraft, used to control the trim of the controls, i.e. to counteract hydro- or aerodynamic forces and stabilise the boat or aircraft in a particular desired attitude without the need for the operator to constantly apply a control force. This is done by adjusting the angle of the tab relative to the larger surface.

Automated trim tab adjustment system method and apparatus

A trim tab control system adapted to adjust trim tabs to optimize the velocity of a water vessel. The trim tab control system is adapted to have a tilt sensor and a velocity sensor in communication with the microcontroller where the microcontroller records the position of the trim tabs based on trim tab adjustments that the trim tab control system initiates, as well as trim tab adjustments initiated by the helmsman of the water vessel.

Auto tab control system

A boat trim tab system having an automatic controller for positioning trim tabs to perform user selected preset functions or maintain previously used positions in response to real time operating conditions. The system is intended to be a stand alone system that is installed on a boat using a master control module to operate the trim tabs and a manual keypad to provide a user interface to the master control module. The system gathers real time data from a variety of onboard sources and uses the data to determine the optimal position of the trim tabs to enhance boat performance.

Trolling motor system with auto retract

A boat control system includes trim tabs mounted on the lower transom of a boat, with an electric trolling motor attached to each tab. The control system controls positioning of the trim tabs within a trim range and within a troll range. If a main engine ignition switch changes from off to on while the trim tabs are within the troll range, the control system automatically moves trim tabs positions out of the troll range, and disables the trolling motors.

Automatic trim for power boats

A trim tab (18, 204) hinged (19) at the bottom edge of a boat transom (12, 179) is rotated into a position below the boat when the drive (58, 186) is in a lowest-most trim position, and is raised up, when the drive is above a selected pickup trim position. A push tube (58) connected to the motor (16) operates a push rod (49) and a trim tab (18). A push bar (96, 97) is moved by the drive, causing pieces (104, 105) to rotate trim tabs (18a). A fluidic slave cylinder (142) is operated by a master cylinder (134) or by a pump (148) responding to a position detector (150). Levers (164, 167) may be connected by a cable (155). A hydraulic master cylinder (195) is disposed on a part (186) of an outdrive that rotates for trim, its cylinder rod (200) contacting a fixed part (184), driving fluid to a slave cylinder (201) mounted on a fixed part (183) with its piston rod (202) moving a trim tab (204).

Trim tab control

A trim tab control system determines current tab position based upon a feedback signal that represents incremental motion of the actuator drive motor. Prior to power down, the current tab position is stored in non-volatile memory, and is retrieved on power up. The control system characterizes the actuator during a learning function by driving the actuator between the upper and lower limit positions and counting the number of increments. The display of tab position is based upon the current tab position count and the number of increments in a full range of motion. Automatic up and down commands cause the actuator to be driven up or down until a stop command is received or a limit position is reached.

Illuminated trim panels

A vehicle trim panel is illuminated from behind to create an illuminated design (e.g., logo and / or lettering) includes a transparent layer and an opaque layer with an opening(s) in the shape of the design. An opaque or partially opaque design piece may be placed over the opening(s) in the opaque layer and be lit around its edges. The vehicle trim panel may be formed by forming a panel with a transparent layer and an opaque layer. An opening in the opaque layer may be formed by removing opaque material (e.g., by machining or laser etching) or by masking (the mask is placed between the opaque layer and transparent layer and removed taking a portion of the opaque layer with it). A design piece may be placed over the location of the opening in the opaque layer.

Trim tabs and surface drive propeller bite control

A trim tab of resilient material affixed in a cantilever fashion at the stern of a boat and of a regressive flexural stiffness such that when deflected, the undersurface of the trim tab assumes the shape of a progressive curve in the direction of water flow. A trim tab of a progressive curve which has gas or liquid ejection to the undersurface to control the boundary layer. A trim tab located under a surface drive whereby the bite of the propeller is controlled relative to the trim tab and the trim tab is controlled to optimize the boat hull.

Trim tab position monitor

A trim tab monitoring circuit is provided which receives a signal that is representative of a voltage potential across a stator winding of a motor which is attached to the trim tab. This signal is passed through a high pass filter to remove the DC component of the signal, amplified, and passed through a low pass filter to remove certain high frequencies components of the signal. A zero crossing detector is used to discern individual pulses which are then received by a counter that provides a single output pulse for a predetermined number of input pulses. The series of output pulses from the counter are conditioned and, in conjunction with a direction sensor, provided to an up / down counter controller that provides digital signals to a signal output circuit. The signal output circuit provides a DC voltage output to a display and the DC output voltage is representative of the position of the trim tab.

Methods and arrangements for rapid trim adjustment

Methods and arrangements to rapidly adjust the trim of a watercraft are disclosed. More specifically, embodiments comprise a sensor to quickly detect changes in the trim angle of a watercraft and a driver adapted to effect rapid changes in the trim angle. For example, many embodiments include large hydraulic pumps and hydraulic connections to adjust the angle of a trim adjuster such as the angle of trim tabs, an outboard motor, or a stern drive. Some embodiments implement high torque electric motors or high capacity pneumatic systems. The drivers may, for example, effect changes in the angle of the trim adjuster within two seconds. In one embodiment, the driver may effect a change in the trim angle within one second or less.

Pivotal trim tab hull

A boat hull configured to create a desired wake shape through a combination of two distinct hull types that interact with the water flow at specified moments. Controlled shaping of the wake shape is achieved through redirection of water flowing across the transom of the main hull, onto a secondary transom of a secondary “diffuser” suction hull that creates a negative pressure that sucks the aft portion of the boat hull into the water, thereby immersing the secondary transom into the water where it can effectively interact with the water and “carve” the desired wake shape desirable for wake surfing.

Jack plate operated trim for power boats

A jack plate (9) moveable upwardly and downwardly between various positions has a trim tab (28) disposed on a fixed portion (10) of the jack plate near the base of the transom (11) of a boat. The moveable portion (12) of the jack plate has a push cap (44) that, at a pickup position of the jack plate, pushes a rod (43) which rotates a lever (38) to move an arm (33) to push the trim tab (28) into an operative position aft of and below the hull of the boat. Above the pickup position, the push cap does not contact the rod; a return spring (50) causes the trim tab (28) to rotate upwardly, into a position where it is ineffective.
