Abstract: 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.

The diving computer also has a number of pre-programmed displays that may be selected, each of which present different layouts and organizations of diving related information.

Abstract: An internal support structure for a tent having a shell is disclosed. The internal support structure comprises at least one internal support structure configured to provide structural support to the shell, the internal support structure having a pair of gussets each having a member extending from the gussets. The members are configured to engage the shell and provide structural support to the shell. The internal support structure is disposed adjacent to the shell without occupying space in the middle portion of an internal space defined by the shell.

Abstract: 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.

Abstract: A dive computer that includes heart rate monitoring capability is provided. The heart rate monitoring is accomplished by a belt that fits around the diver's chest, and the information is wirelessly transmitted to the dive computer. The heart rate information may be displayed during and after a dive, and the dive computer may selectively utilize the monitored heart rate information to compensate the decompression algorithm based on workload during the dive. The dive computer can also utilize the monitored heart rate information to compensate the decompression algorithm based on workload on the surface before and/or after the dive for no fly and repetitive dive calculations.

Abstract: An inflatable air beam having a laceloop assembly affixed thereto, a structure utilizing same and a method of constructing a structure is provided. In the structure, the fabric is laced to a structural support, typically, an air beam to position and properly tension the fabric thereon. The laceloop assembly includes spaced apart adjacent laceloops that are interconnected to secure the fabric panel to the structural support. In practicing the method, the laceloops are passed through fabric panels and through adjacent laceloops to interconnect the adjacent laceloops and secure the fabric panels to the structural support.

Abstract: A wired camping tent providing electric power at a number of electrical receptacles installed therein is provided. The wiring harness delivering the electric power to the receptacles is held within sleeves that are affixed to the main tent covering or fabric. Electric power is provided by a rechargeable battery system, and control of the electric power distribution to the individual outlets is provided by a switch control box. The wired tent includes an accessory support structure at an overhead electrical receptacle installation point, as well as accessory shelves provided in proximity to the other electrical receptacles. An overhead electric fan and light combination accessory may be provided.

Abstract: A tent that includes a swivel portion is disclosed. The tent includes a canopy, a plurality of tent frame components and a swivel portion coupled to at least one of the tent frame components and the canopy. The swivel portion pivots between a relaxed position in which the canopy is in a relaxed state and a tensioned position in which the canopy is in a tensioned state.

Abstract: An internal support structure for a tent having a shell is disclosed. The internal support structure comprises at least one internal support structure configured to provide structural support to the shell, the internal support structure having a pair of gussets each having a member extending from the gussets. The members are configured to engage the shell and provide structural support to the shell. The internal support structure is disposed adjacent to the shell without occupying space in the middle portion of an internal space defined by the shell.

Abstract: A liquid crystal display (LCD) for a sonar depth-finding device includes a matrix of pixels, each pixel having a first dimension and a second dimension greater than the first dimension such that a ratio of the second dimension to the first dimension is approximately an integer value greater than one. Pixels in the matrix are configured to be operatively associated by the sonar depth-finding device to define a substantially square combined pixel.

Abstract: A trolling motor for use with a watercraft is disclosed. The trolling motor comprises a head portion, a propulsion unit, a shaft coupling the propulsion unit to the head portion, and a mounting system configured to secure the trolling motor to the watercraft and to pivot the trolling motor between a deployed position and a stowed position. The mount system comprises a base having a first portion adapted to be mounted to the watercraft and a second portion adapted to receive the trolling motor, a pivot member coupled to the base and configured to pivot between the deployed position and the stowed position, and a damper mechanism coupled to the pivot member and configured to impede the movement of the member as the pivot member is being moved between the deployed position and the stowed position.

Abstract: A valve assembly and a regulator for use therein are disclosed. The valve assembly includes a valve poppet having a first end having a first face and a second end having a second face.
